One Piece: Starting with Sharingan, First Mate Uchiha

As Caesar pressed a button, the massive ventilation system surrounding the research institute suddenly emitted a piercing grinding sound, and then began to run wildly in reverse.

The purple "slime" gas, which had been kept out by the heavy alloy door, finally found an outlet.

It rushed wildly into the various passages of the research institute through the thick ventilation ducts and the gaps damaged by the battle.

The piercing red highest-level alarm instantly resounded throughout the entire massive underground facility.

The constantly flashing red light made the cold metal walls look like a hellish landscape.

Sanji, Nami, Franky, and the others, who were in the maze-like corridor of Building B, looked in horror at the deathly poison fog that was rapidly approaching from behind like a purple tsunami.

The purple gas churned and hissed as it passed over the steel floor.

"Run, everyone! Don't stop!"

Sanji roared, standing protectively on the outermost edge of the group.

They had no choice but to urge and lead the still-terrified giant children as they raced with all their might deeper into the research institute.

Meanwhile, in another intricate network of steel passageways.

Zoro, Robin, and Kin'emon, a samurai from Wano Country, are anxiously searching for a way to escape.

Behind them, the hissing sound of poison gas spreading could also be heard.

Suddenly, the temperature in the passage ahead plummeted, and tiny ice crystals formed in the air.

Accompanied by a biting gust of cold wind, an exceptionally thick and massive ice wall rose from the ground without warning, instantly sealing off the entire wide passage and completely cutting off their way out.

A strange figure slowly descended atop the icy wall, where the air was thick with cold.

She was a beautiful green-haired woman with pure white wings and legs that had transformed into sharp bird claws—Monet, the Snow Maiden.

A strange and chilling smile curled at the corners of her lips as she looked down at the three people below.

"This road is blocked, everyone."

"Stay here obediently, be consumed by the poison gas, and become the stepping stone for the young master's hegemony."

As he heard the hissing sound of poison gas getting closer and closer from behind, Zoro's eyes suddenly turned cold.

Without uttering a single word, he drew the famous sword from his waist with a backhand motion, a chilling glint flashing across its dark blade.

He stepped forward, blocking the crowd, and without turning his head, he hissed at Robin and Kin'emon behind him:

"Leave this to me, you guys don't need to worry about me, just go!"

Robin took a deep look at Zoro's reliable back. Knowing her companion's strength, she decisively activated the Flower Flower Fruit's power, and together with Kin'emon's slash, directly tore a large hole in the steel wall on the side.

The two quickly passed through the hole in the wall and continued their escape, leaving this cold, deserted battlefield to the great swordsman of the Straw Hat Pirates.

……

The scene cuts back to the central control room at the deepest part of the research institute.

Caesar was sweating profusely, staring intently at the monitor screen in front of him.

He discovered with despair that his prized deadly gas was ultimately unable to stop the two men's advance.

Just as he was preparing to activate the backup defense mechanism.

A muffled metallic wail suddenly came from the superalloy blast-proof wall beside him, which was said to be impenetrable even by heavy artillery.

Immediately afterwards, a huge fist-shaped mark suddenly bulged out on the smooth wall surface.

The next second, "BOOM—!!"

With a deafening roar, the expensive superalloy wall was shattered like a fragile paper toy by an extremely brute force, turning into countless flying metal fragments!

Amidst the billowing smoke and dust, Luffy's fist, still wreathed in white steam from intense friction, stood out starkly through the hole.

He raised his hand and casually patted the dust off his straw hat, his once clear eyes now turning icy cold.

He stared intently at Caesar, who was slumped to the floor in terror inside the control room:

"finally found you!

"You're that perverted scumbag who likes to poison innocent children, Caesar!"

"I'm going to beat you to a pulp today!"

As soon as Luffy finished speaking, Victor walked in through the large hole that had been smashed open, hands in his pockets, looking completely relaxed.

He thoughtfully took the broken door debris with him and used his ability to seal the gaps, keeping out the poisonous gas that was trying to rush in.

Faced with Luffy's murderous aura and relentless advance, Caesar experienced a brief moment of panic before suddenly remembering his absolute home-field advantage as a Logia-type Devil Fruit user.

He floated up from the ground, turning into a cloud of gas, and let out a nauseating, maniacal laugh:

"Whoosh whoosh whoosh whoosh!"

"Don't be so arrogant, you mere pirate!"

"Do you think you can defeat me with just brute force?"

"In this room, I am the absolute god!"

Luffy roared, not wanting to listen to his nonsense, and suddenly pushed off with his feet, preparing to charge forward and finish the fight with one punch.

However, as soon as he took a step, his body suddenly stiffened.

A strong wave of dizziness struck his brain like a hammer blow.

Luffy opened his mouth wide, clutching his throat tightly with both hands, desperately trying to breathe, but it felt as if the surroundings had become an absolute vacuum, and he couldn't breathe in even a single drop of air.

His legs buckled, and he collapsed onto the cold floor with a thud, writhing in pain as his face quickly turned bluish-purple.

Caesar, transformed into a cloud of purple gas, floated in mid-air, looking down at Luffy struggling on the ground, smugly showing off his trump card:

"Whoosh! Feeling the pain?"

"My Gas-Gas Fruit ability can instantly drain all the oxygen within a certain range around me!"

"For you creatures who need to breathe, there is no air."

"No matter how powerful the Haki or how formidable the Devil Fruit ability, it only leads to death!"

Having said that, Caesar took a lighter out of the pocket of his white coat and held it high.

A cruel glint flashed in his eyes as he prepared to detonate the high concentration of gas he had already released, burning the suffocating straw-hatted boy to a crisp.

"Farewell, Straw Hat Boy!"

Caesar laughed wildly and lit the lighter in his hand with a "click".

However, the smile on his face suddenly froze the moment the flame lit up.

Out of the corner of his eye, he suddenly noticed that the man with one red and one purple eye was standing quietly in the same spot.

Viktor crossed his arms and looked at him with a mocking gaze, as if he were an idiot.

Moreover, Viktor's complexion remained normal, showing no signs of oxygen deprivation or suffocation whatsoever.

Caesar's eyes nearly popped out of their sockets, his face filled with disbelief.

He was of course unaware that Viktor's abundant chakra could circulate internally in such extreme conditions to temporarily maintain his life.

Victor glanced at the smug Caesar, a hint of undisguised mockery flashing in his eyes:

"Drain the oxygen? Is this the only trick you can pull?"

"When it comes to playing with gas tricks, it seems you've chosen the wrong opponent to show off to."

Before he finished speaking, Viktor's hands moved in a blur in front of his chest, rapidly forming hand seals.

"Wind Release: Great Breakthrough!"

Viktor took a deep breath and exhaled sharply forward.

A violent gust of air, like a Category 12 hurricane, exploded in the relatively enclosed control room!

This incredibly powerful wind-style ninjutsu not only instantly shattered Caesar's prized high concentration of gas, but also...

Furthermore, the violent wind pressure forced fresh air from the external passage back in, completely breaking the oxygen-free predicament.

As fresh oxygen rushed in, Luffy, who had been struggling in pain on the ground, suddenly took a deep breath.

"call--!"

As the lungs were instantly filled with oxygen, Luffy's eyes, which had been glazed over from suffocation, lit up again in an instant.

"You bastard!!!"

With a deafening roar, Luffy stomped his legs hard on the ground.

He was like a cannonball fired from a gun, his right fist instantly enveloped in dark, cold Armament Haki.

His gaze was fixed on Caesar, who was being blown about by the gale in mid-air, his face filled with terror!
