"Dragon Slayer's Secret Art: Crimson Lotus Exploding Flame Blade!"

"Dragon Slayer's Secret Art: Karma Demon Iron God Sword!"

"Dragon Slayer's Secret Art: Shattering Light - Sky Drill!"

Natsu, Gajeel, and Wendy unleashed their respective Dragon Slayer Secret Arts, their attacks striking the meteor. The meteor exploded in the sky like a firework.

"What? The meteor was destroyed!"

Natsu, Gajeel, and Wendy landed back on the ground, surrounding Irene, who was in her dragon form, from four directions.

It might have seemed ridiculous for four humans to surround a dragon, but that was the reality of the situation. Irene, her voice harsh, said, "Don't think that destroying the meteor means you've won!"

"You are merely humans, after all!"

Erza looked at Irene. "Aren't you human as well? And you hate your dragon form. Why don't you turn back into a human..."

Irene was momentarily speechless, cut off by Erza's words.

...

"Acnologia is here. Have those five dragons already lost?" The Magic Council's chairman, Hyberion, said.

Councilman Wolfheim shook his head. "They must have been injured."

Wolfheim was one of the four strongest mages on the continent, also known as the Four Gods of Ishgar.

Acnologia and the dragons' battle was witnessed by everyone. In their hearts, they all believed Acnologia was stronger.

"He's injured, and he still dares to come here? He doesn't take us seriously!" said Org, another member of the Four Gods of Ishgar. He was ranked third and was known for his bad temper.

"Let us meet the Black Dragon of the Apocalypse."

Acnologia's roar reached their ears, and soon, they saw his figure.

The Magic Council's Rune Knights attacked Acnologia. He roared, flapping his wings. The resulting wind was like sharp blades, destroying the surrounding buildings and sending the knights flying.

"Don't be reckless!"

Wolfheim transformed into a large beast-man and charged at Acnologia. Acnologia swatted him away as if he were a mosquito.

Councilman Warrod quickly used his plant magic to catch Wolfheim.

Wolfheim coughed up blood, staring at Acnologia in disbelief. "He's so powerful.."

"My Bloodsucking Magic is useless, too!"

Hyberion, who had transformed into a form similar to that of the vampire from the pirate world, said with a grim expression.

Jura summoned countless vines and rocks, but they were instantly shattered by Acnologia.

Unless it was Dragon Slayer Magic or an extremely powerful, high-level magic, Acnologia was practically immune to other types of magic.

Acnologia roared, "I need magic power..."

He opened his mouth, sucking in the magical power of those around him. To mages, it was as if their life force was being drained. The feeling was similar to when a Devil Fruit user fell into the sea.

Even after devouring the souls of the Nine Demon Gates, Acnologia was still close to losing control.

He didn't even know if anyone had tried to stop him. The current Wizard Saints might have been strong, but compared to Acnologia, they were several levels weaker than even the weakest of the Spriggan 12 and Zeref.

To him, they were like ants. The Wizard Saints were helplessly and ignominiously defeated.

The current chairman of the Magic Council, Hyberion, lay on the ground, in disbelief. "Is this Acnologia? How can we defeat such a monster? Is this the end of humanity?"

"Roar!"

The terrifying roar shook the very earth. Although he was just one individual, he was the strongest force in this world.

"The Black Dragon... Acnologia..."

"So big!"

Many of those present had never seen Acnologia before. They had only heard of him. And the reason was simple: most of those who had seen him were dead.

Acnologia looked at Irene, who had transformed into a dragon. He sensed the presence of Dragon Slayer Magic on her, and also on Natsu, Wendy...

"I didn't expect to find Dragon Slayers here. You should all die!" Acnologia hated dragons the most. His family and people had been destroyed by dragons. Dragon Slayers would eventually become dragons, and he was the Dragon King, destined to eliminate all dragons.

"So, it's you. I didn't expect you to still be alive. The one who gave humans the power of Dragon Slaying, the Creator of Dragon Slayer Magic, the Dragon Queen..."

Irene was the creator of Dragon Slayer Magic. Acnologia had also been a Dragon Slayer once. They were from the same era, so it was natural that he knew Irene.

Both were legendary figures among Dragon Slayers. Now, they faced each other in their dragon forms. The two dragons clashed.

Towns were completely destroyed by the shockwaves of their battle. Fortunately, Fairy Tail was located in a remote area of Magnolia. Only their guild members and the client were present.

After just a few exchanges, Irene was already struggling. Acnologia's attacks left her scales torn, and dragon blood rained down.

Although they were both Dragon Slayers who had transformed into dragons, her strength was still far inferior to Acnologia's.

Especially now that Acnologia had absorbed a large amount of magical power, his strength had increased significantly.

However, to ensure that he could kill Ian, Acnologia decided to absorb even more magical power.

"Pa!"

In mid-air, Acnologia seized an opportunity and kicked Irene.

Boom!

Irene plummeted from the sky.

"Ugh... Aaaahhh!"

Irene spat out a mouthful of dragon blood. Before she could even get up, Acnologia landed, stomping on her.

"You are too weak. Become my power!" Acnologia opened his mouth wide, beginning to devour Irene's dragon power.

Although it wouldn't significantly increase Acnologia's power, he needed a large quantity.

Dragon power was a great supplement to Acnologia, especially the dragon power of Irene, who could already transform into a dragon. If he absorbed Irene's dragon power and Zeref's soul, he could then go and settle the score with that damn demon.

Irene's dragon power was visibly being absorbed by Acnologia. Nearby, August, who was fighting Gildarts, suddenly warned, "It's not good! We can't let her dragon power be absorbed. Otherwise, no one will be able to stop Acnologia. Your Majesty did this to obtain Fairy Heart and have an endless supply of magical power!"

"Only then would we have a chance to defeat Acnologia. This was the purpose behind the founding of the Alvarez Empire. In other words, we don't need to fight now. Gildarts, stop this!"

Everyone's expression changed. But there was nothing they could do. Suddenly, golden lightning fell from the sky, striking Acnologia. He stumbled, and his absorption of Irene's dragon power was interrupted. A voice called out.

"Yo, we haven't been gone that long, and the guild's already been destroyed."

"Fire Dragon's Brilliant Flame!"

While Acnologia was staggered, Natsu appeared behind him, above his head. He combined the flames in his left and right hands, creating a massive, burning fireball that he hurled at Acnologia. The explosion sent Acnologia tumbling forward, and Irene was freed.

"Laxus!"

Natsu was also surprised. Golden hair, a lightning bolt scar over his left eye, the guild mark on his left chest, and earphones. It was Laxus, the strongest mage in Fairy Tail after Gildarts and Makarov.

"I discovered the five dragons fighting Acnologia by the sea. I knew something was wrong with the guild... They're all dead, Natsu..."

"Iron Dragon's Club!"

Gajeel formed a massive iron club, dozens of meters long, and swung it at Acnologia. He had just been sent rolling by Natsu's attack and hadn't regained his balance. He was struck by the club and sent flying like a baseball.

"It's okay. Igneel and the others told us. Even without Acnologia, they would have disappeared... They just wanted to buy us some time."

Natsu said with a smile, but everyone knew that he, Gajeel, and even Wendy were deeply saddened.

"We're useless..." Gajeel said.

"Grandeeney wouldn't want to see us cry. We can only defeat Acnologia..." Wendy wiped her tears.

Acnologia, enraged, said, "Did you think that just because of this level of magic, you could limit my actions? Magic is useless against me!"

"Dragon Slayer's Secret Art: Crimson Phoenix Blade!"

Natsu, using his strongest attack, shrouded his entire body in compressed flames, transforming himself into a blade as he charged towards Acnologia.

Boom!

"Aaaahhh!"

Acnologia screamed in pain. Natsu's attack had caused him minor injury. Acnologia, furious, shouted at Natsu.

"Dragon Slayer's Secret Art: Thunder Dragon's Firing Hammer!"

Laxus transformed his body into lightning, appearing behind Acnologia in an instant.

He gathered a large amount of golden lightning in his fist and struck Acnologia, sending him crashing to the ground and creating a large crater.

"Amazing! Are Fairy Tail mages really this strong?" August was shocked as he watched Natsu and the others.

The mages of the Alvarez Empire generally looked down on the mages of Ishgar.

But now, it seemed that the mages of Ishgar were not as weak as they had thought. However, he then realized that they were Dragon Slayers who had traveled through time, as well as Irene's daughter and his own uncle.

"Laxus, welcome home!"

The demonized Mirajane also came to Laxus's side.

As one of the guild's strongest S-Class mages, there were rumors of a relationship between them. Others were afraid of Laxus.

But the demonized Mirajane looked at him with a strange, almost admiring look. If Lucy were here, with her imagination, she would probably say, "There's something going on between them."

"Mm, I'm back..." Laxus replied softly. Then he looked at Erza. "Erza, there's someone else... We met on the way."

...

"It really hurts, you little bugs!"

Acnologia stood up again, his aura growing even stronger. Everyone could sense his anger.

Time and time again, he had been knocked down by those he considered Ants. It was humiliating. He hadn't wanted to waste energy or let these Dragon Slayers escape.

That's why he hadn't been serious at first. But now, these little bugs had actually managed to injure him.

Seeing Acnologia, who had suffered so many powerful magical attacks yet was still unharmed, everyone's expression changed.

Acnologia's body was surrounded by dense, dark orbs of light.

These dark orbs transformed into beams of light, indiscriminately covering an area of thousands of meters.

Boom! Boom! Boom!

Each dark orb that exploded was comparable to a powerful spell. Acnologia's magical power was too strong. His powerful dragon power, when used to cast magic, made it impossible to resist.

"Seven Stars Sword..."

Seven beams of light shot towards them, but they were blocked by seven other shooting star-like beams. A figure wearing a mask and a cloak appeared before them.

Everyone cried out, "Mystogan!"

"No, isn't Mystogan in that world? Then he's... Jellal..."

"Erza!" Jellal looked at the stunned Erza, who tearfully nodded. "Jellal..."

"That's great, Miss Erza..."

Wendy said softly.

Laxus, displaying a rare passion, roared, "Let's save the reunion for later. Dragon Slayers, let's slay some dragons..."

"Ooooohhh!"

Gajeel and Natsu shouted like monkeys, jumping up and down. Erza and Mirajane spoke, "Let him see the power of Fairy Tail..."

"Iron Dragon's Club!"

"Fire Dragon's Iron Fist!"

The Dragon Slayers attacked with all their might, not giving Acnologia a chance to react. Although their attacks were practically useless against him, Natsu roared, his fist burning with flames.

He punched Acnologia hard. Although their power was decent, to Acnologia, with his near-immunity to magic and powerful body, it was like being slapped.

"Iron Dragon's Sword!"

Gajeel joined his hands, forming a massive iron sword that he swung at Acnologia. Although he didn't take any real damage, it still stung a little.

"Bastards!"

Acnologia opened his mouth, roaring.

"Full-Body Take Over!"

"Demon: Fallen Angel Lucifer!"

Boom!

Mirajane's body radiated immense magical power, and her form slowly began to change. She spread her hands, and a dazzling purple-black light shone.

When the light faded, a fallen angel of extreme beauty, clad in a gorgeous purple-black, form-fitting battle armor and with three pairs of black wings, floated in mid-air. A golden halo adorned her head.

Black, shining feathers fell to the ground, disappearing into light. She looked absolutely stunning.

"Heavenly Armor!"

Erza also unleashed the armor she could only use after releasing her Second Origin. Because it consumed so much magical power, it was said that no one had ever been able to wield it for long. She had almost never used it.

But now was clearly not the time to hold back. This armor was her strongest, far surpassing her Lightning Empress, Sea King, Flame Empress, Adamantine, Wind God... and other armors in power, and its consumption was also the greatest.

She wore a crown-like headdress, her long hair tied back in twin ponytails. She wore a six-sided, three-dimensional lion's head pauldron on her shoulder, and a long, flowing, ankle-length sash that resembled a heavenly robe.

Her upper body, arms, and waist were covered in cloth armor, while her legs were clad in knightly greaves. She wielded a sword and a halberd. This was her most ornate armor.

"Soul Extinction!"

Mirajane joined her hands, unleashing a flash of light comparable to a dragon's roar.

If Ian were here, he would definitely recognize the similarities between her Demon and Fallen Angel forms and his own Second and Third Releases.

"Heavenly Armor, Starfall!"

Erza swung her twin swords, sending crescent moon-shaped slashes towards Acnologia. They were almost on par with the slashes of a master swordsman in the One Piece world.

"So beautiful..."

Seeing Mirajane and Erza's transformations, Laxus and Mystogan, or rather, Jellal, couldn't help but blush and compliment them.

"Lightning Dragon's Halberd!"

"Nine Heavenly Stars!"

But they couldn't fall behind. Laxus raised a halberd made of lightning and hurled it at Acnologia. Jellal summoned nine dazzling stars from the sky, which descended upon their foe.

"Absolute Zero World!"

Gray also unleashed a power comparable to Aokiji's Ice Age, freezing everything in its path.

"Karma Demon's Iron Spiral!"

"Shattering Light - Sky Drill!"

Gajeel leaped into the air, holding a gigantic black iron drill. A fierce wind gathered in the air, forming a penetrating spear.

"Evil Explosion!"

At this time, August had his hair standing on end, his skin red with white stripes. This was his strongest combat form. He raised his staff, unleashing several attacks at Acnologia.

"Enchant: Detonate!"

Irene also waved her staff, enchanting Acnologia's body with an explosive spell.

It was a pity or a blessing that her power to control dragons was useless, otherwise she wouldn't have needed to use such a method.

"Full Break!"

Gildarts shattered the ground beneath him, unleashing his ultimate Crush magic. The ground turned to dust. Even August was sweating bullets, not having used his full power.

"A Touch to Extinguish All!"

A transparent pillar of light struck Acnologia, and space itself seemed to fracture.

Boom! Boom! Boom! Boom! Boom!

Almost everyone unleashed their strongest attacks. After all, they were facing the Dragon King of the Apocalypse.

All the areas shrouded in black light were shattered. August and Irene quickly retreated. After a while, the light gradually faded, revealing a massive hole in the ground.

Acnologia stood there...

"No way..."

Everyone was dumbfounded. Igneel and the other dragons had sacrificed their lives, yet they had failed to defeat Acnologia. Now, they had unleashed their strongest attacks.

Yet, he still stood there unharmed.

Was this the power of the Dragon King of the Apocalypse?

"Nothing is impossible. He's just stronger than us." August said. He understood that such an outcome was highly unlikely.

Acnologia was too powerful. He was a being that completely surpassed them. They even doubted if Zeref, even with Fairy Heart, could defeat him.

An endless supply of magical power was simply providing Acnologia with an endless supply of food. August seemed to have made up his mind.

"Irene, I will open a path for you. You must take them and escape. After all, they are also family."

"August..." Irene was surprised, looking at him. She didn't know what August was planning. When faced with a powerful enemy, people often make certain choices.

Even if resistance was futile, it took courage to fight back. But choosing to sacrifice oneself to attack the enemy required even greater courage.

"Ever since I was born, I possessed immense magical power. Because of this, I was abandoned and shunned... When I was on the verge of death, His Majesty saved me. So, even if I have to give up my life, I will do it for His Majesty."

"Disperse, along with my life!" August began to chant. Irene's eyes widened.

"This is... the ancient magic that evaporates living beings' blood and melts the earth, Ars Magia!"

"The price of using this magic is one's own life." Irene understood. Now that she and August were facing Acnologia, they were no match for him. Continuing to fight would only lead to death.

And, recalling the story Mavis and Zeref had told, she guessed that August might be... Then, the members of Fairy Tail were their family. He had to buy Zeref time.

So, he chose to use this suicidal attack, hoping to heavily injure the enemy. Perhaps this was their only chance. Having made her decision, Irene gently touched the ground with her staff.

Gray's expression turned serious. He immediately knew what August was planning. It was similar to his master Ur's Iced Shell.

It was a spell that sacrificed one's own life. This type of magic was often incredibly powerful. Acnologia, sensing the danger, flapped his wings and charged towards August.

"Foolish human, did you think you could kill me with a forbidden spell? Let me show you the true power of the Dragon King!" Acnologia roared, opening his jaws wide.

Everyone watched in horror. They had almost forgotten that although Acnologia was in dragon form, he was originally a Dragon Slayer. He could devour any magic, including that of other Dragon Slayers.

But they also understood that August's goal wasn't to defeat Acnologia, but to buy time for Zeref.

A terrifying explosion erupted in the clouds, creating a mushroom cloud that painted the sky a bloody red. The shockwave from the explosion destroyed the clouds.

The resulting blast swept across the land, destroying everything in its path.

The earth trembled violently, cracking under the strain. August's magic was dispelled. This was a forbidden spell of self-destruction on par with Iced Shell.

However, after sacrificing his life, August's attack was dispelled by Acnologia, and the shockwaves from the blast alone razed the town of Magnolia to the ground.

Fortunately, it was on the coast, so most of the blast went out to sea, creating a tsunami.

At this time, inside the Fairy Tail guild.

"August sacrificed himself..."

"What?" Mavis was shocked. He had just learned that August was his son, and now he was dead.

But given August's age, his lifespan was likely coming to an end anyway.

"It's almost time. It's time to absorb Fairy Heart and leave this world."

Zeref walked towards Mavis, who was sealed in the Lacrima crystal. The seal on the crystal shattered, and Mavis's body fell out.

Then, Mavis's fingers twitched. Zeref and Natsu both widened their eyes in surprise. Soon, Mavis slowly opened her eyes and stood up.

"I'm alive..."

The First Master looked at her hands, in disbelief. Zeref and Natsu were also stunned, especially Zeref. He had been the one to curse Mavis, so how could she still be alive? Mavis immediately conjured a set of clothes, covering herself.

Zeref, though shocked, quickly composed himself. "It's surprising that you're alive, even though your life was taken by the curse. Perhaps this is the power of Ankhseram, the God of Life and Death."

"Zeref..."

"Although I'm happy to see you alive after nearly a century, I still need to take Fairy Heart." Zeref said, appearing behind Mavis and embracing her, transferring Fairy Heart to himself.

"Aaaahhh!" Mavis screamed in pain, looking at Zeref with anguish.

"Don't look at me like that. And don't pity me. Pity yourself. I'm going to start over. But you will continue to struggle in this world. I will return to 400 years ago, when my parents and my cute younger brother were still alive. I will not become the Black Wizard. Nor will Acnologia appear. That way, I can save the entire world."

Zeref released Mavis, who collapsed to the ground.

But Ankhseram's curse was not so easily undone.

Otherwise, he wouldn't have spent so many years and so much effort trying to kill himself. She was only weakened from having her magical power drained.

She would recover soon enough. Zeref spread his arms, his magical power surging outwards like waves, affecting everyone. They all felt the immense power.

"!"

"This is..." Makarov's expression changed drastically. The members of Fairy Tail who had been transported to the guild also felt a sense of foreboding.

Irene, too, smiled. "Your Majesty, you've succeeded?"

...

...

"Zeref... He really did such a cruel thing to his own son. Following his father to attack his mother." Ian said, his voice calm.

Before him, in mid-air, a child of about one year old had formed, with short blond hair.

He looked somewhat similar to Mavis and Zeref. This was August as a child.

In the world of Fairy Tail, both Ain's Rewind and Bonney's Age-altering magic could turn people into children. Even Im's Time-Time Fruit could probably do the same.

This was the chance he had given August to start over. But he hadn't done it for nothing. He had used Brannish's Memory Magic to seal his memories. He would regain them as he grew older.

"Wah, wah..."

Clearly, the infant August was well-behaved, waving his little hands at Ian. But in an instant, he was held by a golden figure.

"You've finally come out, Zeref..."

Acnologia seeing this, directly opened his mouth, and his Black Dragon's Roar began to gather.

Zeref's body gathered dark magical power, revealing the horrifying power of the most violent, strongest, and most evil legendary Black Wizard in the history of the magical world.

"He's making his move..." Irene and the members of Fairy Tail knew that Zeref was about to attack.

The mages of the continent of Ishgar had only ever heard his name. They had never seen him in person. The horrifying legend of Zeref had been circulating for a full 400 years.

No one could compare to him. No, if there really was someone, it would be Ian who was now revered as a God.

The man who could defeat the Black Dragon Acnologia with his bare hands. Even Zeref, who possessed an immortal body, had never achieved such a magnificent feat, he was trying to escape desperately.

"Darkness Explosion Array"

Zeref immediately used a forbidden spell of black magic, because he knew exactly how horrifying his opponent was.

"!"

The Darkness Explosion Array, and Acnologia's Black Dragon's Roar collided, causing an extremely horrifying destructive force.

The shockwaves reached an area of thousands of meters.

Boom

Zeref's expression changed. From this exchange, it was clear who was stronger.

"What? Are you starting to fear death after living for so long?"

Zeref's changing expression was noticed by Acnologia. And during this conversation, Acnologia transformed into his human form.

He was barefoot, his ragged clothes and spiky hair fluttering in the wind. He had white dragon markings on his face, and his hands had completely transformed into claws.

Zeref snorted coldly, quickly gathering a large amount of dark energy in his hands, then attacking Acnologia, who quickly dodged.

"So fast"

Zeref was startled by Acnologia's speed. Perhaps the dragon form was stronger, but without a doubt, the human form was more agile.

"Roar"

Zeref spread his hands, unleashing his dark energy. Everything around him withered, and the soil seemed to die. However, it only corroded Acnologia's upper clothing.

This completely exposed the Wings of Annihilation on his chest. His magic resistance and defense were far too high.

"Ankhseram's Curse?"

Acnologia said, charging at Zeref again. He had seen Ankhseram's Curse before, but he still shouldn't touch it carelessly. He couldn't guarantee he would survive if he was careless.

"That's right. Although this thing will have a considerable impact on me, in a sense, it has also been protecting me."

Zeref's hands were wrapped in dark energy as he fought Acnologia.

"Four hundred years is a long time. I've also learned how to control my emotions" Zeref said.

Ankhseram's Curse would activate when the cursed one cherished life, and then it would indiscriminately deprive the surrounding life force.

"Immortality, huh? That's really an enviable power. Even though I became the Dragon King, my lifespan, although long, is still limited... And if I devour you, I should be able to become immortal. But if I were you, I would have used these four hundred years to become stronger, then personally defeat me. Instead, you wasted your time researching how to commit suicide and how to escape."

Zeref's face was ferocious.

"Acnologia, You're just a monster..."

"Excuses. You simply wanted to but didn't do it. The proof is your clumsy fighting technique..." Acnologia dodged Zeref's fist, then kicked him in the body, shattering his bones.

"Aaaahhh"

Zeref screamed, sent flying.

"It seems you've been quite pampered these past 400 years. But it also seems like no one has fought you..." At this time, Zeref slowly crawled up, as if the sound of bones breaking was just an illusion. Zeref looked as if he hadn't been injured at all. Acnologia frowned. "So this is immortality..."

Immortality meant that even if one was killed, they would come back to life. Zeref's face showed no sign of happiness.

"See? This is Ankhseram's Curse. As long as it exists in this world, its rules are absolute. Even you, Acnologia, can't kill me..."

Whoosh

Acnologia clenched his fist, and a vast amount of magical power surged, striking at Zeref. Cracks appeared in the space before his fist.

Zeref raised his hands, creating a dark shield.

Boom

The dark shield was struck, and his body was sent flying. He spat out a mouthful of blood, but he quickly recovered. As long as he had enough magic power, he could quickly recover from any injury.

Acnologia began to attack Zeref up close. Zeref also began to fight back.

Crack

"Aaaahhh"

Zeref's arm was shattered by Acnologia again. Zeref screamed, and his arm drooped to his side. Just as Acnologia was about to pursue and shatter Zeref's head, he activated his 'Death Predation' ability.

"My only way to truly be saved is to return to a time when my memories, my parents, and my brother are still alive. Then I will relive my life. I will no longer become immortal, and I will not let Acnologia become as powerful as he is today. I will stop him beforehand and then save the world"

...

...

"Infinite Magic"

"This is the power that transcends time and space..." Zeref's appearance had changed drastically.

His body had turned white, including his hair, clothes, and pants, as if they had all turned white.

Behind him were a pair of wings made of white, glowing magic.

The Black Wizard had become the White Wizard. Zeref's hand, which had a hole in it, quickly healed. He stared intently at Acnologia.

His eyes shone with fighting spirit.

He was still the Black Wizard, feared by the world. How could he possibly retreat now?

Boom

Zeref's body exuded powerful magic. Acnologia took a step, and his body instantly appeared before Zeref. He kicked at Zeref, who quickly raised his arm to block.

Boom

A horrifying shockwave erupted from where they collided. The ground beneath them completely shattered. Zeref's arms were broken, but they quickly healed.

Time and space were now under Zeref's control. He could return his state to a time before he was injured. But just as Zeref healed, Acnologia kicked his shoulder.

He was sent flying, and Zeref desperately tried to stabilize himself. The spot where Acnologia had kicked him, the white divine power covering it, had a hole. Zeref's face changed. He hadn't expected that even his divine power, fused with Fairy Heart, could be broken.

If his divine power, which represented a part of his consciousness, was broken, then he might truly die. To die, such a foreign word.

"No... I can't die. I want to live. I still have to save the world. I can't die here" Divine power covered Zeref's shoulder, and in an instant, Zeref healed the injury on his shoulder. Zeref waved his hand, mobilizing powerful magical energy to attack Acnologia.

Boom Boom Boom

One magic bullet after another shot towards Acnologia. Acnologia kept dodging Zeref's magic attacks.

Whoosh

Acnologia appeared before Zeref, extending his dragon claw to grab him.

"Black Shield"

Zeref shouted. A black energy shield, centered on him, spread outwards, covering everything, taking away all life. This was the side effect of Ankhseram's Curse. And the other side effect was something many people sought after: immortality.

This Ankhseram's Curse had caused Zeref great pain in the past. But he also had to admit that it was a very powerful attack. However, even in this infinite darkness, Acnologia stood tall.

The ground, as if struck by a meteor, formed a massive crater. Zeref panted, looking at Acnologia.

Boom Boom Boom Boom

Zeref's body was uncontrollably sent flying backwards, smashing through several boulders. The divine power on his abdomen had been dispersed again.

Acnologia didn't continue to attack. After a while, Zeref's divine power once again covered his body.

"No way"

Zeref looked incredulous, completely losing the imposing air he had when he first obtained divine power. He had begun to doubt his own strength and power.

He had calculated Acnologia's power.

Logically speaking, after obtaining Fairy Heart, even if he wasn't much stronger, he should have been able to escape from Acnologia's hands.

But why was he being beaten from the beginning?

"An endless supply of magic? Heh. It's just more food for me."

In an instant, he saw Acnologia's appearance begin to change.

The dragon markings on his face expanded, turning into dragon scales that appeared all over his body.

Dark magic power radiated, devouring, destroying, and annihilating everything. The entire world trembled

...

Zeref unleashed a surge of powerful magic, charging towards Acnologia. Acnologia raised his hand, slashing it down towards Zeref's fist.

A shockwave erupted

Zeref gathered immense power in his hand, unleashing it towards Acnologia. The collision of their energies created a catastrophic explosion

Crack

Zeref's arm was severed, and it fell to the ground. The divine power on the severed half dissipated, restoring it to Zeref's normal arm.

"Aaaahhh"

Zeref screamed in agony, quickly using his divine power to heal his arm. Although Zeref possessed infinite magic power, he was still inferior to Acnologia in raw strength.

He was being completely outmatched. Zeref realized that Acnologia hadn't been using his full power during their previous encounters. Now that he was fighting without holding back, his combat strength had practically doubled.

It reminded Ian of his battle with Im, who also controlled the power of time and space.

Zeref might have possessed more magical power than Im, but his mastery over time and space was far inferior, almost nonexistent.

That was understandable. Im had controlled that power for 800 years.

Thud Zeref's head was suddenly seized by Acnologia, who then slammed him into the ground. Acnologia flapped his wings and sped forward, dragging Zeref along the ground, creating a deep trench. Zeref struggled in vain.

Acnologia suddenly threw Zeref into the air. Black light gathered in his mouth, condensing into a small, dark sphere.

Black Dragon's Roar

Whoosh

A wide beam of black light shot towards Zeref, exploding into a beautiful firework.

"Aaaahhh"

Zeref screamed in agony. Parts of his body lost their white glow, revealing his original form.

But soon, the white light once again covered Zeref's body, and his injuries quickly healed. The infinite magic power of Fairy Heart greatly enhanced Zeref's strength, including his regenerative abilities. He flapped his wings, hurtling towards Acnologia in the sky.

"Darkness Explosion Blast"

Zeref raised his hands, and a massive, dark fireball appeared above him, hurtling towards Acnologia like a miniature black sun.

Acnologia met it head-on, colliding with the Darkness Explosion Blast. The attack was shattered.

In an instant, Acnologia had reached Zeref. Zeref couldn't believe that his magic was unable to stop him.

Acnologia appeared before Zeref, his black dragon claw reaching towards him.

"Ugh, aaaahhh"

Zeref's body was severely wounded. Zeref immediately screamed in pain.

Acnologia's tail wrapped around Zeref's neck, cutting off his screams. He placed his index finger on Zeref's chest.

Black magic power gathered at Acnologia's fingertip. "This is the price you must pay, It's over"

A black magical blast struck Zeref's chest, tearing through the white light and revealing his original form. Zeref's chest was pierced, leaving a gaping hole.

Acnologia released his tail, and Zeref's body plummeted to the ground.

Boom

Zeref crashed to the earth.

"Ugh, aaaahh"

Zeref groaned in pain. He raised his hand, unleashing a magical shockwave that struck Acnologia, halting his pursuit.

Zeref used this opportunity to quickly heal himself.

...

The members of Fairy Tail and Irene watched in stunned silence. Even the Spriggan 12, who believed that Zeref, after obtaining Fairy Heart, could crush everything, including the Black Dragon Acnologia, They couldn't have imagined this outcome.

"It's over... Zeref"

Acnologia looked at Zeref. Zeref could be said to have run throughout the entire Fairy Tail story.

Without Zeref, perhaps there wouldn't be the current Fairy Tail. Although he seemed unwilling to kill and had a kind heart.

But he always did evil things, and very evil things at that. Perhaps Zeref himself had realized that some of the things he did were simply wrong, so he sought ways to commit suicide.

But that made the world even worse. For Zeref, the best outcome was only death.

Zeref's face was filled with terror as he watched Acnologia approach. The infinite darkness completely swallowed his white, not only his magic power but also his soul.

At the moment he was swallowed by the light, Zeref's face showed a relieved and grateful smile. The light dissipated, and where Zeref had stood was now empty. He had vanished without a trace.

...

All the members of Fairy Tail looked at the battle from afar. After devouring many people's magic power.

Acnologia's own magic power could be said to have reached a horrifying levels. Even from such a distance, they felt their bodies trembling.

If they were close, the result would be that they wouldn't even be able to stand. The Black Dragon Acnologia was the nemesis of all mages.

Acnologia's body ascended higher and higher, becoming brighter and brighter. The light of the sun was absorbed by him. It was as if two suns had appeared in the sky.

Everyone present was an elite mage, so they could naturally see what Acnologia was displaying now. It was the ability to absorb the sun's light and transform it into his own power.

...

At this moment, everyone was stunned. They didn't expect that the Dragon King, who had devoured and destroyed everything, would transform into a golden dragon after absorbing the White Wizard Zeref.

Moreover, Acnologia's every move, the light was constantly changing and transforming.

Lightning, iron, wind, ice, fire... even Zeref's Time-Space, and his own darkness

Where there is light, there is shadow, and light is made up of various elements such as lightning, iron, wind, ice, and fire...

There was no doubt that Acnologia had now become a God who controlled everything.

...

...

They couldn't help but look at Ian beside them.

If anyone could defeat him...

"This feeling of becoming a god and controlling everything is quite good, isn't it? Now what do you want?"

Ian looked at Acnologia and asked faintly. No one knew when, not even the members of Fairy Tail noticed, but he had appeared opposite Acnologia.

"It can be seen that you still retained some humanity before. Now it has been completely restored with the improvement of your strength"

When he first watched Fairy Tail, he felt that Acnologia's actions were very confusing, including Zeref's.

Acnologia already possessed the power to rule the entire world. He didn't rule and rarely destroyed. Of course, rarely is relative to four hundred years.

If Acnologia was diligent, it wouldn't take four hundred years, maybe just one year, and the world would be destroyed. Therefore, Zeref was very puzzled by Acnologia's actions.

Now, Ian understood. Although Acnologia's body had completely turned into a dragon, he still retained a bit of humanity and rationality.

In these four hundred years, Acnologia had been suppressing his actions with humanity and rationality.

He didn't appear in front of humans for the same reason. He was afraid that he would not be able to suppress his desire to destroy.

...

"Humanity, what is humanity? I am the Dragon King, Acnologia. No... now I should be the Dragon God" Acnologia roared loudly

He gathered horrifying magic power in his mouth. It was a roar, the Black Dragon's Roar, aimed at Ian

A horrifying explosion occurred

It was like a nuclear bomb had exploded, a mushroom cloud appeared. The shock wave from the explosion spread out, destroying everything it encountered.

After a while, the smoke from the explosion slowly dissipated. A huge pit appeared on the ground, as if a meteor had crashed there. There was no sign of Ian in the center of the pit.

Acnologia frowned. He didn't believe that Ian would be wiped out by that roar. At this moment, behind Acnologia, space rippled, and a black gap appeared. Ian emerged from the black gap. He immediately turned his head

"Black Cero"

Black light. Swallowed Acnologia. In the next instant, Acnologia's figure flashed, and he suddenly rushed towards Ian

...

Acnologia's heart roared wildly, and he forcefully broke free from Ian's spatial confinement. After all, he also knew space-time magic.

"A little bit stronger..."

Ian looked at the Black Dragon Acnologia in the sky and said with a hint of disdain at the corner of his mouth.

The current Dragon God Acnologia was at most at the same level as his third-stage release.

However, one was magic power, and the other was the soul.

After all, before his third-stage release, he also had various attribute abilities such as ice, fire, iron, and wind... They were just missing a God Tree fruit that connected the world.

...

The Black Dragon hovered in the sky, staring down at Ian.

Suddenly, it roared, and a horrifying surge of magical power gathered

It wasn't just darkness, but also light, time, space, lightning, iron, fire, wind, ice... all sorts of different elements

This was the Black Dragon's full-powered roar... No, perhaps it should be called the Dragon God's Roar.

It was powerful enough to obliterate not just Tenrou Island, but an entire continent in an instant.

In the next moment, before the shocked eyes of everyone present, the Black Dragon's devastating roar, which seemed capable of shattering even space itself, was met by Ian, who simply extended a single finger, gently touching its center.

Then, the roar, like ancient, decaying wood, instantly crumbled into dust, scattering across the heavens and the earth.

A single finger had shattered the Black Dragon King's roar, an attack capable of annihilating an entire continent.

"..."

The members of Fairy Tail were stunned, murmuring to themselves as they stared at the figure in the sky, taking deep breaths, a sense of awe in their hearts.

"I suppose you've never seen my strongest form, have you? Well then, let me show you..."

"Boom"

...

"Resurrección"

As Ian's words fell, an even more horrifying black spiritual pressure erupted from his body, forming a black storm around him that shot into the sky

The entire world shook violently, as if unable to withstand this spiritual pressure.

Even the sky above him darkened. Behind him, his black wings, vast enough to blot out the sky, unfurled menacingly.

The half, horned, white, skull-like helmet on his head had become a complete, two-horned helmet, even more sinister than before.

The black claws on his hands had become long talons, and his hair seemed to have grown longer.

The tear marks under his eyes had deepened and thickened, becoming even more prominent.

"Is this your power? How weak"

Acnologia mocked him, but he felt a vague sense of unease. His aura hadn't actually increased, in fact it had slightly decreased, but it continued to erupt like a volcano, continuously rising.

The upper half of his clothes gradually disappeared. Black liquid flowed from his eyes, and the lower half of his tear marks extended into two lines.

His abdomen, legs, arms, and back were covered in black feathers. The lower half of his outfit was now split in two.

His wings fully unfurled, revealing sharp, bat-like claws. The horns on his helmet grew longer, sharper, and more menacing.

He grew a long, freely controllable tail, tipped with a sharp, bone-like object. Everyone who saw this scene was stunned, because wasn't this similar to their own demon transformations?

But the transformation continued. Black, feather-like energy scattered and danced in the air. His hair grew longer and longer, turning from black to white.

The whites of his eyes turned gold, and his pupils became vertical slits, like those of a beast.

His tail also turned white, and at the base of his tail, at his tailbone, a blue-black flame seemed to ignite.

"An angel..." Happy said, shocked.

"No, a Fallen Angel" Carla corrected. The members of Fairy Tail were speechless. This world had various beliefs in gods, and there were legends of God and angels.

...

"Humph, a fallen angel? I am now also the Dragon God!" The Black Dragon Acnologia opened his massive jaws, aiming to devour Ian.

Just as Ian was about to lose his focus, Acnologia's fist, imbued with dense, dark dragon power, struck at Ian.

Black Dragon's Iron Fist

Ian also clenched his fist, gathering immense, black spiritual power, and met Acnologia's fist head-on.

Darkness vs. Darkness. Iron Fist vs. Steel Skin

Boom

A horrifying shockwave erupted from the point of impact between Ian and Acnologia's fists.

The entire world seemed to shake violently. Ian and Acnologia's fists, the space around them shattered, and the shockwaves spread outwards.

"Waaaahhhh"

The members of Fairy Tail were sent flying by the shockwave, screaming. The horrifying spiritual pressure soared into the sky.

From the moment Ian had entered his first Resurrección, the sky had been displaying strange phenomena, each one more powerful than the last, leaving everyone bewildered.

This time, Ian's form had changed slightly again. The two pairs of wings on his back had grown, becoming four pairs of black, feathered wings.

Six wings… then eight wings covered his whole body

"Four pairs of wings?"

According to the legends, the number of wings an angel possessed determined their rank and power. The highest recorded rank was the six-winged Seraphim, but this being had eight wings. Was he a god, then?

"Demon, you've angered me…"

Acnologia's was furious. He unleashed a torrent of dark energy, striking at Ian.

Then ten wings…

Ian's entire body was enveloped by the wings, a symbol of his status: a High-Ranking God.

Whoosh

Ian clasped his hands together, then slowly pulled them apart.

A Garganta appeared in his hands. Acnologia, seeing this, narrowed his eyes, but he wasn't afraid. He was a higher being than Ian, so he charged forward.

A golden light appeared. A Gran Rey Cero pierced through Acnologia's wing, then it began to shatter. The golden light shone in the sky, engulfing Acnologia's body.

"Aaaahhh"

Acnologia screamed. When the smoke cleared, his wings were in tatters, and he was covered in wounds.

He was severely injured. He glared at Ian. He was the strongest Dragon King, but now…

the sky above cleared, and a ray of sunlight shone down.

His injuries began to heal, and he even felt himself growing stronger. But he was also afraid.

Behind Ian, a twelfth wing had appeared.

"Do you understand now? You don't need to understand. When I came to this world, your fate was sealed. Let me put an end to everything" Ian placed his hands in front of him.

He struck the pose for Fairy Tail's ultimate magic, Fairy Law. This was, in the eyes of the guild members, but in reality he was compressing the entire world. Acnologia's eyes widened.

The world was shrinking, as if the entire galaxy was being compressed into Ian's hands. He knew his end had come, but if he gave up now, he wouldn't be the Dragon God Acnologia.

"I am the Black Dragon Acnologia, the the Dragon God, The Strongest being in the world Who can judge me? Who dares to make me repent?!"

"Only I can judge others. No one can judge me.. DIE!" The Black Dragon Acnologia roared, gathering horrifying dragon power and the power of the sun in his mouth.

"It's over"

Ian clasped his hands together, then slowly pulled them apart. His body emitted an even brighter golden light. A voice like a divine bell echoed in the sky.

The clouds dispersed, and a golden beam of light shot from Acnologia towards Ian.

The Black Dragon Acnologia roared, and a golden energy shockwave shot from his mouth. But the entire world seemed to expand, then contract. The golden roar returned to Acnologia's body.

The world turned white… Was the world destroyed? That was what everyone thought.

When the world regained its color, Acnologia was gone, and so was the god.

The ruined town of Magnolia was also restored to its original state.

Outside the World of Fairy Tail.

In the void, Ian, dressed in a casual black outfit, flew swiftly.

The void was like a dimensional universe that encompassed countless worlds. In a normal universe, there were countless planets.

But here, there were countless worlds.

Membranes, crystal walls, bubbles

They represented distances of near, middle, and far. In the void, they could be seen everywhere, especially the distant bubble worlds, like a misty starry sky, numbering in the billions.

Ian followed a faint connection, constantly traveling through this vast expanse of worlds, finally arriving in front of an oval-shaped world covered in black and white airflow.

The terror of the void was such that, without protection, even someone as strong as Kaido or Whitebeard would be instantly torn to pieces.

But resisting wasn't the only way through. With spatial abilities, one could use clever techniques to avoid the chaotic spatial forces and navigate through the gaps, drifting with the current.

But this was clearly unnecessary for a god like him, who could withstand space

"Is this the direction…"

Ian, following a faint connection, roughly judged the location of his destination.

In this void, Ian's figure was moving forward, impervious to the spatial forces, ignoring them.

"Here it is"

Looking at the world before him, Ian's eyes flickered. He was sure his perception was correct.

That was the membrane space of the One Piece world.

"I'm finally… back"

Standing before the world of One Piece, Ian could almost see through the world to the face of Tashigi, whom he hadn't seen in a long time.

A smile appeared on his face as he prepared to take a gentle step forward and enter.

"Oh, I almost forgot this…"

As he spoke, he opened a Garganta, and a giant, black dragon crystal appeared in his hand. He tossed it into the endless void.

Perhaps it would be swept into some world by the Turbulence of time and space, allowing the man who had helped him kill Ulquiorra to obtain it.

The magical power of Fairy Heart had already been devoured by him. What he lacked most now was physical power.

They complemented each other perfectly.

After doing this, Ian prepared to return to the world of One Piece.

...

Thank you all for sticking with me and reading this far! :)
