One Piece: Starting with Sharingan, First Mate Uchiha

In front of the cold research institute gate

Law held the long, slender nodachi "Kikoku" in one hand, his deep gaze fixed on Sanji, who was standing at the edge of the light barrier.

He slightly raised his hand, his fingertips shimmering with blue light, just about to test the true strength of this Straw Hat Pirate.

"Whoosh—!"

A sharp whooshing sound suddenly came, interrupting Luo's actions.

The heavy jitte, inlaid with seastone and imbued with powerful and sharp Armament Haki, slammed mercilessly into Law's back.

Luo reacted swiftly, swinging his "Ghost Cry" to block.

With a thunderous clang of metal clashing, Smoker transformed into billowing smoke, forcefully intervening between the two and landing steadily on the ground.

Smoker, with a burning cigar between his teeth, exhaled a thick cloud of smoke, his fierce, hawk-like eyes fixed on Law.

"Your opponent is me, Trafalgar!"

"Although I am a Marine, I am eager to capture Straw Hat Luffy and his cronies immediately."

"But now, I'm more curious about what kind of shady secret you're hiding on this sealed-off island!"

Faced with the tense standoff between the two powerful figures, Sanji stood at the edge of the light barrier and calmly took a deep drag on his cigarette.

He knew all too well that it was a very unwise choice to fight head-on in a space where others had complete control.

Moreover, his primary task now is to protect Nami and those giant children of unknown origin.

Then hurry up and meet up with your single-celled captain who's always running around.

Sanji slowly exhaled a blue smoke ring, a cold smile playing on his lips:

"It seems that there are irreconcilable internal conflicts between your Navy and the Seven Warlords of the Sea."

"In that case, I won't stay here and disturb your enjoyment any longer."

With that, Sanji suddenly exerted force with his feet and unleashed his signature move, "Sea Step".

He stepped into the air, creating a series of deafening sonic booms, as if stepping on transparent stairs, and instantly rose into the air, neatly breaking out of the blue light shield of "ROOM" and speeding away.

Law simply watched Sanji leave without making a move to stop him.

He now had to focus all his energy on dealing with this extremely difficult vice admiral.

……

Meanwhile, Sanji sped through the fog and soon reunited with Nami and the others who were retreating.

They led the group of crying, enormous children through the harsh environment of thunderstorms and toxic fog.

After a search, the group finally found an abandoned research institute branch that was half-buried underground in the desolate ruins, which they used as a temporary shelter.

However, just as everyone settled down in the ruins, a strange change occurred.

Several enormous children suddenly clutched their heads, their bodies beginning to convulse violently again.

And this time the symptoms were more severe than when they occurred at the cookie shop.

Their eyes rolled back, their faces contorted in agony, as they pounded the hard wall like mad beasts.

They cried out loudly for "candy," their huge fists swinging wildly, nearly smashing Usopp, who was trying to calm them down, into a pulp.

Upon witnessing this horrifying scene, Chopper immediately rushed forward, risking being thrown into the air, and drew blood from the sick child again for testing.

Looking at the cloudy reaction in the test tube, Chopper came to a chilling conclusion:

"These kids aren't eating candy at all!"

"It contains a potent stimulant called 'NHC10'! It also contains prohibited drugs that cause abnormally large body sizes!"

"Once the medication is stopped, they will go insane, feeling like they're living a life worse than death, and..."

"Long-term use of this poison will drastically shorten their lifespan, preventing them from reaching adulthood!"

Seeing the children suffering terribly from drugs, writhing on the ground in agony, Chopper's bottom line was completely shattered.

He shed hot tears mixed with anger and sorrow, his small body trembling violently.

"Snapped!"

Chopper smashed the glass medicine bottle in his hand to the ground with a hysterical roar:

"Unforgivable... I'm a doctor!"

"I absolutely must cure them, no matter what method I have to use!"

"I'm absolutely going to beat that bastard who used innocent children for human experiments to a pulp!"

……

An exploration team venturing through dense fog.

On the broad back of the centaurs with tea beards, Kin'emon, a samurai from Wano Country, was dressed in his finest attire.

He knelt respectfully on horseback, solemnly thanking Luffy and the others who had saved his life, and explained with a sorrowful expression his true purpose for risking his life to land on the Navy's forbidden island:

"I've come to find my son, Momonosuke, who has strayed onto this poisonous island!"

"I would give my life for my son!"

Upon hearing that the other party had come to this dangerous island to search for their son, Luffy grinned without hesitation, patted his chest vigorously, and readily agreed to help:

Don't worry!

"Since you treated us to such a hilarious performance, we'll help you find your son while we're at it!"

Viktor, who was riding on another centaur, paused slightly when he heard the name "Momonosuke".

He looked at Robin, who was nestled in his arms as they rode together, and felt her unique elegance and gentleness.

Viktor's eyes narrowed slowly.

It's decided, Momonosuke must die!

No one can stop it!

……

Meanwhile, deep within the heavily guarded control room of Punk Hazard.

Caesar Courland was staring intently at the monitor screen on the wall.

When he saw his experimental subjects being taken away by the Straw Hat crew, he was so angry that his face twisted, and he smashed the expensive wine glass in his hand to pieces.

"Damn Navy! Damn Straw Hat Crew!"

"They actually kidnapped all my precious experimental subjects!"

Caesar was filled with panic.

He knew all too well that if the secrets of these gigantic experimental subjects were discovered and exposed by the Navy, it would be disastrous.

His backer, Doflamingo "JOKER," would definitely kill him without hesitation to silence him.

He had to kill them to silence them before things were exposed.

With trembling hands, Caesar picked up a special video Den Den Mushi and dialed a secret underground channel.

As the call connected, his twisted face was filled with murderous intent, and he issued the coldest order:

"Go, brothers of Yetikur!"

"Use your assassination skills to wipe out all those pirates, leave no one alive!"

"Get those children back to me, safe and sound!"

Upon receiving the order, two enormous, mysterious yeti-like creatures, appearing and disappearing intermittently, met at the junction of the island's perpetually shrouded poisonous fog and snow-capped mountains.

Carrying specially made sniper rifles, they lurked like ghosts in the thunder and fog, beginning their relentless hunt.

……

Outside the main gate of the research institute, the battle between Law and Smoker had entered a fierce, life-or-death struggle.

The two fought fiercely from the collapsed ground all the way up into the air.

Smoker brought the power of the Smoke-Smoke Fruit to its fullest potential, achieving incredible mobility. The billowing white smoke transformed into countless fists, constantly blocking Law's movements.

Luo's slashes were even more effective within the "ROOM" space, making them almost impossible to defend against.

The naval soldiers who couldn't retreat in time and the huge warships docked on the shore had been cut to pieces by Rona's unpredictable spatial swordsmanship, turning into countless fragments scattered haphazardly on the ground.

After a most intense clash of Armament Haki.

Ron's cold eyes precisely captured the moment Smoker reverted from elemental form to physical form.

Law's eyes suddenly turned cold. He lunged forward, his right hand's five fingers pressed together, the fingertips coated with high-frequency electromagnetic waves powerful enough to pierce the heart, and thrust it fiercely towards Smoker's unsuspecting chest:

"Mes scalpel!"

As Smoker let out a painful groan, an unbelievable scene unfolded.

A light block emitting a faint blue glow was forcibly shaken out of Smoker's chest by Luo!

And in the center of that transparent block of light, a vibrant, real heart is beating!

"Lieutenant General Smoker!"

Tashigi, standing at a distance, saw this scene and screamed in terror, drawing her famous sword and rushing forward to fight to the death.

With his heart gone, Smoker's eyes rolled back, and his tall body fell heavily onto the cold snow.

Just as Luo sneered, reached out and tightly grasped the still-beating heart, preparing to end the battle once and for all—

"Wow! It's so lively here!"

The stalemate outside the research institute's gate was instantly broken by an unusually excited and familiar shout.

Luffy, Victor, Zoro, Robin, and others, riding towering centaurs, broke through the thick fog like divine warriors descending from the heavens.
