OP: My Aircraft Carrier Evolves#1+2: Crushing King Wapol to Death, Kingslayer, Jin Acquires the Munch-Munch Fruit!

Sea Circle Calendar, Year 1516!

Paradise—First Half of the Grand Line.

Drum Island!

After the old king's death from illness, the Drum Kingdom—renowned throughout the world for its advanced medical expertise—welcomed its new ruler, Wapol.

The citizens, still mourning their beloved former king, would soon find their grief replaced by something far worse.

Unlike his father, Wapol had been a spoiled prince from birth, pampered beyond reason and rotten to the core.

Upon ascending the throne, he immediately enacted absurd laws to cement his power, driving the entire nation into chaos.

—————————

One year later.

Before departing for the World Government's Reverie, Wapol issued his most heinous decree yet—the "Doctor Hunt" law—determined to secure his regime once and for all.

Only the twenty doctors willing to serve him exclusively would be spared: the "Doctor-20."

Just two Doctors managed to escape this purge: Dr. Hiriluk and Dr. Kureha, who remained at large despite the manhunt.

When Wapol returned from the Reverie and learned of their survival, he spread false rumors that the Doctor-20 had fallen gravely ill.

—————————

This night.

A blizzard raged.

Despite knowing it was a trap, Dr. Hiriluk—driven by his unwavering faith in medicine—arrived at the castle to treat the supposedly dying Doctor-20.

Facing the king and his guards, weapons drawn and ready, Dr. Hiriluk calmly sat down and pulled out his sake.

"Thank goodness—there are no patients after all. I was worried something terrible had happened to our country."

"What a relief... it was just a trick to lure me out."

"You people can't kill me."

"Let me ask you—when does a person truly die? When a bullet pierces their heart?"

"WRONG."

"When they're struck by an incurable disease?"

"WRONG AGAIN."

"When they drink soup made from a poisonous mushroom?"

"OF COURSE NOT."

"It's when they're forgotten by the world..."

"Even if I disappear—"

"My dream will live on. That dream will definitely cure the sickness in this country's heart."

"What a wonderful fucking life I've had."

He raised his cup to the sky and drank the bomb-rigged sake.

BOOOOOOOOOOOOOOOOOOOOOOOM!

Cherry blossoms bloomed—pink as snow, beautiful beyond words.

The ultimate beauty.

Wapol stood over the blood-soaked ground, hands on his hips, laughing triumphantly—completely oblivious to what was happening behind him.

Through the howling blizzard, a bizarre circle materialized in the air, as if a portal had suddenly torn through space-time itself.

"DR. HIRILUK!"

A figure—human-shaped yet reindeer-like—charged across the snow, tears streaming, roaring in fury.

Wapol's men immediately raised their guns and swiveled their cannons toward the newcomer.

At that moment—

Dalton, the guard captain moved by the scene, knew the "snow monster" stood no chance against Wapol. He stepped forward to block the creature's path.

Urging him to flee immediately.

CRACK!

Thunder suddenly split the sky, shaking the entire castle. Dalton spun around to see a massive object plummeting from above, wreathed in lightning.

CRASH!

Wapol and his men had no time to dodge. The colossus crashed down on them, purple-red electricity erupting everywhere.

An blinding energy dome formed, its searing light sending both Dalton and Chopper flying.

They were stunned.

"WHAT THE FUCK IS THAT?"

"What's happening?"

After about a minute, the lightning and energy began contracting inward, gradually revealing the true form of the massive object.

"A ship??"

Dalton's first thought was that it looked like a vessel—yet completely unlike anything sailing the seas today.

Its exterior gleamed silver-white, as if forged from pure steel. The deck stretched flat for roughly twenty meters, with no towering masts in sight.

Instead, there was a bridge island.

Too bizarre.

"THE KING!"

"KING WAPOL!"

"HIS MAJESTY IS TRAPPED UNDERNEATH!"

The guards' panicked shouts snapped Dalton back to reality. He looked beneath the vessel—Wapol had vanished completely.

Could it be...?

Ignoring Chopper, Dalton rushed over and pressed both hands against one side of the behemoth, trying to rescue Wapol.

"Hey, get over here and help!"

The guards scrambled forward on hands and knees. These parasites who'd grown fat on the king's authority feared nothing more than unexpected disasters.

Chopper stood frozen. Wapol—Dr. Hiriluk's killer—had been crushed to death?

What was he supposed to do now?

He had no idea.

Just then, he saw a door open on the bridge island. A young man emerged, holding a wrench, looking utterly bewildered.

"Achoo!"

The icy wind hit Jin like a sledgehammer, making him shiver violently.

"What the hell?"

"Where am I?"

Suddenly—

He heard incomprehensible shouting. Turning, he saw a man with an afro and mustache leap onto the deck.

The mustached man wore boxing gloves, looking fierce as he bellowed a stream of words at Jin.

"Did I... end up overseas?"

"What are you saying? I don't understand! Got any clothes? Let me borrow a jacket—achoo! Did I drift to the Arctic?"

The blizzard was overwhelming. Jin had to shout back, using hand gestures to communicate.

The mustached man saw him waving the wrench. Not only was the enemy refusing to surrender—he was resisting? Unforgivable. He couldn't let this stand.

He charged forward.

His gloves crackled with static electricity as he swung at Jin.

Planning to take down the king's assassin in one strike.

"Static Shock Punch!"

Starting a fight without warning??

Jin jumped back in alarm, raising his guard—thankfully, he'd trained in boxing for two years at university.

But the man's speed—it was insane!

Just as shock registered—

BAAAAAAAAAAM!!!!

A tall figure suddenly materialized before him, arms raised to block the mustached man's punch, electricity sparking off his body.

"Hey, are you okay?"

A furry, blood-stained face turned back with concern.

Jin: "Holy shit, a monster?"

"Am I dreaming? Still asleep?"

Wait a second...

He stared at the somewhat familiar face, memory gradually overlapping with recognition. Then he exclaimed: "Chopper?"

Despite the language barrier, the pronunciation of "Chopper" was remarkably similar.

Chopper's eyes widened in surprise: "Eh? You know me?"

Jin could guess his question from the expression. Even as his mind reeled with shock, he nodded.

I've been isekai'd!

Crossed into the world of One Piece??

Jin was stunned.

He'd been an aircraft carrier enthusiast who'd spent years of savings building a scale model carrier for himself.

When online critics called his carrier model just an empty shell, he'd personally sailed it downriver to the coast to prove them wrong.

Along the way, the secondhand engine had broken down. While fixing it, everything had started shaking—he'd thought it was a storm.

He never imagined he'd be cluelessly transported to another world.

—————————

"Opening!"

The mustached man spotted Chopper's distraction and grinned wickedly. He lunged forward with a devastating static uppercut, putting everything behind it.

BAAAAAAAAAAM!

Too young and inexperienced, Chopper was caught completely off-guard. The punch sent him tumbling backward seven or eight meters.

Jin's pupils contracted.

That's Chopper.

Which means this bastard is Kuromarimo?

Wapol's affairs officer, one of the Bliking Pirates' officers.

In the world of One Piece, even ordinary people possessed extraordinary physical abilities.

Though Kuromarimo was just an officer in a trash-tier pirate crew like the Bliking Pirates, he was still beyond Jin's ability to handle.

"I'VE GOT YOU NOW!"

Kuromarimo sneered, lunging forward.

Jin retreated while desperately thinking of a plan.

At the critical moment—

The deck split open into a massive mouth that swallowed Kuromarimo whole, leaving Jin drenched in cold sweat as he stumbled backward.

What was that?

A MOUTH?

<><><><><><><><>

Drum Island—a winter island locked in eternal snow, where blizzards howled like vengeful spirits.

Just outside the castle of the Drum Kingdom... Chopper gritted his teeth against the pain and rolled to his feet.

He had to save the person who'd avenged Dr. Hiriluk.

But then he saw it—

The steel ship beneath his feet suddenly split open into a massive, tooth-filled maw that swallowed the mustached man whole in one gulp.

The sight made his eyes bulge from their sockets.

"EH??"

"What the hell was that?"

He leaped back in terror.

Afraid he'd be next on the menu.

Dalton and the surviving guards heard the commotion and vaulted onto the deck, all witnessing the same impossible scene.

Everyone froze.

That was just—

The image sparked something familiar.

Dalton, ever the voice of reason, spoke first: "That's King Wapol's Paramecia Devil Fruit power—the Munch-Munch Fruit."

The Munch-Munch Fruit?

The guards erupted in celebration: "King Wapol's alive? Your Majesty, did you swallow this ship? Is that you?"

Whoooosh.

Wind whistled across the deck. No answer came.

"No. The ship itself ate the Munch-Munch Fruit."

Dalton's worldly experience kept him calm.

When he had accompanied Wapol to the Holy Land of Mary Geoise, he had seen an object infused with a Devil Fruit in the hands of Spandam.

The celebrating guards' smiles turned to ice.

King Wapol's Devil Fruit had been "eaten" by a ship?

Devil Fruits only transferred when their previous host died, reappearing randomly somewhere in the world.

Now it had transferred.

Which meant—

"KING WAPOL IS DEAD!" a guard shrieked in terror.

"His Majesty is dead."

"He killed King Wapol."

"KINGSLAYER!"

"Bastard—seize him! Avenge King Wapol!"

Panic gave way to rage. They projected their own failures onto the strange young man before them.

Capture him. Kill him. Give the citizens someone to blame.

Besides—

Whoever avenged Wapol would be a hero.

When the next king took the throne, rewards would follow.

Wapol might be dead, but the old king's bloodline lived on—there was still an exiled prince out there.

Bring him back.

They'd remain the kingdom's elite.

Someone raised a rifle and fired.

BANG! BANG!

Flintlock bullets screamed through the air.

The gunfire jolted Jin from his stupor. He raised his hand instinctively, and the carrier's deck immediately erected a wall of reinforced steel plating.

DING! DING!

The bullets bounced off harmlessly, not even leaving scratches.

Others charged forward with swords.

The deck opened its mouth—they tumbled inside.

Some didn't make it two steps before collapsing, convulsing on the ground with their hair standing on end, blue static electricity crackling across their bodies.

Dalton frowned. Kuromarimo's static electricity?

The Munch-Munch Fruit absorbed whatever it consumed, making it part of the body—but it could absorb human abilities too?

Dalton had never seen Wapol demonstrate this. Was it a unique effect of combining weapons with Devil Fruits?

While the guards wailed for their mothers, Jin experienced something extraordinary—he felt his consciousness merge with the ship.

A virtual control interface materialized before his eyes.

——————

"HOLY SHIT!!"

"INFINITE EVOLUTION??"

"MY MODEL AIRCRAFT CARRIER MUTATED??"

"AND I CAN SEE THE REQUIREMENTS TO EVOLVE IT??"

"THIS IS FUCKING INCREDIBLE!"

Jin's shock transformed into wild joy after a deep breath. The world of One Piece was lethal for ordinary people.

Someone who'd crossed over like him—without some kind of cheat ability, he'd never even glimpse the Summit War, let alone participate.

But now everything was different.

Individual combat power mattered, sure—but the ability to wipe out a country with a single shot—like the Three Ancient Weapons—was a deterrent of the highest order.

He could develop quietly, then sail his personally crafted carrier across the seas of this pirate world, unstoppable.

"Gyehe... Gyehehehehe..."

Jin couldn't suppress his wicked laughter. To Chopper and Dalton's ears, it sounded absolutely diabolical.

Chopper flinched in fear, then reconsidered—how bad could someone who'd avenged the doctor really be?

"SO COOL!"

His eyes sparkled as he watched the carrier unleash its power.

Dalton's brow furrowed.

"This guy... dammit!"

He despised the king and guards' behavior, yet duty compelled him to act. He activated his Ox-Ox Fruit power.

"THAT'S ENOUGH! STAND DOWN!" He roared.

Leaping into action, he rescued several guards about to fall into the deck's gaping maw.

Jin glanced over.

Dalton??

The Zoan-type Ox-Ox Fruit: Bison Model user...

His strength was average, but like an ox, he was kind, loyal—the textbook definition of someone who'd take whatever life threw at him.

'I just got here, I don't know the lay of the land, and I can't speak the language. I could really use the help of someone like him.'

Jin's mind raced.

The carrier ceased its attack.

Dalton caught his breath and looked toward the unfamiliar young man, who smiled and nodded, gesturing peacefully.

"He's stopping?" Dalton guessed.

"EVERYONE, LOWER YOUR WEAPONS!" Dalton commanded.

The guards who'd been screaming for revenge moments ago—after getting their asses handed to them—suddenly found clarity and obediently lowered their arms.

Dalton reverted to human form.

He raised both hands to show he meant no harm, then stepped forward: "I am Dalton, Captain of the Drum Kingdom's Royal Guard."

Jin pointed to Dalton. "Dalton!"

??

Jin pointed to himself: "Jin!"

Dalton's eyes widened. "Jin?"

In the common tongue, 'Jin' sounded remarkably like 'King'. Combined with the howling wind and snow, Dalton had misheard.

Could he be the old king's illegitimate son? No, that's impossible! The language barrier was real...

But whether he was or wasn't—

This young man's confident aura...

The unknown power that had fallen from the sky to crush Wapol.

This Devil Fruit-powered ship...

All of it made Dalton wary.

He didn't want to provoke him and bring disaster to the kingdom.

Dalton noticed Jin's thin clothing and shivering. "QUICK—BRING HIM CLOTHES AND FOOD!"

Jin didn't understand but glanced at Chopper.

Chopper froze, then realized—the man trusted him, was asking if it was dangerous.

'I'm being trusted?' Chopper practically glowed with happiness. He eagerly pointed at clothes, then mimed eating.

Jin relaxed and nodded gratefully at Dalton. Now that the tension had passed, he really was freezing and starving.

—————————

Once wrapped in thick furs, with huge chunks of meat and wine spread before him, Jin still cautiously insisted Dalton eat first.

After filling his belly—

Jin yawned and signaled to Dalton that he needed rest and that they should leave and not come near.

At the same time, he put the carrier on alert: Anyone Who Approached Would Be Captured.

Dalton disembarked.

Chopper left too, carrying the hat Dr. Hiriluk had left behind, heading back to find Dr. Kureha.
