One Piece: Starting with Sharingan, First Mate Uchiha

On the cold, desolate land of Punk Hazard, a fierce wind carried poisonous fog that permeated the air.

Smoker led the G-5 branch of the Navy, following the obvious trail left by the Straw Hat crew, and strode towards the huge research institute deep in the island.

However, this group of menacing naval personnel did not walk far before their path was blocked by a figure at the main gate of the research institute.

Trafalgar Law, one of the current Seven Warlords of the Sea.

He casually slung his long, slender nodachi, "Onikiri," over his shoulder, his eyes coldly fixed on the group of uninvited guests.

Smoker stopped and exhaled a thick cloud of smoke.

He gripped the jitte in his hand and questioned Law sharply, asking why, as a Shichibukai, he would appear on this poisonous island that had long been sealed off by the World Government.

Faced with the vice admiral's questioning, Luo remained unfazed:

"This is my private vacation villa. I'm enjoying my leisure time here. Do I need to report to the Navy?"

Smoker frowned, clearly disbelieving.

Luo then calmly added:

"As for the Straw Hat leader, I haven't seen him since the Marineford War."

"There is no one else on this island except me."

Just as Luo was trying to brush off the navy with calm words, the scene inside the research institute was quite different.

Sanji, Usopp, Nami, Chopper, Franky, and the others, after defeating the gas masked troops, ventured deeper and successfully found a huge room called the "Biscuit Room."

Pushing open the door, the scene inside astonished everyone.

This spacious room was filled with tiny children who were enormous, like giants!

These children were experimental subjects who were secretly abducted from all over the world.

Upon seeing outsiders intrude, the children were initially taken aback, but then, sensing Nami and the others' goodwill, they immediately gathered around them as if granted a pardon.

The children's eyes were red and swollen as they surrounded Nami, crying loudly that they wanted to go home and see their parents.

Overwhelmed by maternal love, Nami gently comforted him.

But this heartwarming scene didn't last long before something unexpected happened.

Several children suddenly clutched their heads and collapsed to the ground in agony, rolling around.

Immediately afterwards, as if infected, all the children turned deathly pale, their faces contorted in extreme pain.

They cried and screamed, repeatedly demanding "candy."

"Chopper, what happened to them?!" Nami shouted anxiously.

Chopper immediately rushed forward, opened the medical kit, and quickly drew blood and performed examinations on the sick child.

A few minutes later, when the reagent changed color, Chopper's face instantly turned deathly pale:

"These children..."

"They have potent stimulants and banned substances in their bodies that cause them to grow to enormous sizes!"

"They're experiencing drug withdrawal!"

Upon hearing this cruel conclusion, Nami trembled, abruptly covered her mouth, and scalding tears streamed down her face.

She had proposed to Victor with great anticipation back on the Sky Island that she wanted to have a child that would be a result of their love.

Looking at these children who were being cruelly used as guinea pigs, Nami felt an unprecedented surge of rage and grief.

Franky was so angry he gritted his teeth. He immediately raised the heavy cannons hidden on his steel arms, his roar echoing throughout the cookie shop:

"This kind of utterly depraved laboratory, SUPER—has no reason to continue existing!"

"Children, don't be afraid, let's rush out together!"

……

Outside the main gate of the research institute.

With his privileges as a Shichibukai and his airtight lies, Luo Zheng was about to dispel Smoker's doubts and get away with dealing with this troublesome group of marines.

Suddenly, "BOOM—!!!"

A deafening roar came from behind Luo.

The incredibly sturdy steel gate of the research institute was shattered by a single, devastating "General Cannon" fired from the inside by Franky.

Thick metal fragments flew everywhere like shrapnel grenades.

Amidst a thick, acrid cloud of smoke, Sanji, Nami, Chopper, Franky, and Usopp, leading a large group of crying, gigantic children, burst out of the ruins.

"Run! Everyone stay close!" Usopp shouted from the front.

Just as they rushed out of the gate, the two groups of people bumped into each other head-on at the entrance.

The air seemed to freeze at that moment.

The fully armed G-5 marines were stunned, staring wide-eyed at the group of pirates and giant children who had suddenly appeared.

The Straw Hat crew was also stunned, staring blankly at the Navy standing guard outside the door.

Luo, who had been confidently declaring that "I'm the only one on the island," now had his lips twitching uncontrollably.

Smoker, with a cigar in his mouth, watched this absurd scene and laughed in anger.

He sneered, gripped the Sea Stone Ten Hands tightly with both hands, and stared intently at Luo:

"You just said... you're the only person on this island?!"

When his lie was ruthlessly exposed, Luo took a deep breath and suppressed his anger.

To prevent his massive plan to destroy the SAD factory and overthrow Kaido from being reported to the World Government by the Navy.

Luo had no choice but to forcibly detain all the witnesses present.

"ROOM: Slaughterhouse!"

Luo stopped talking and slightly raised one hand, spreading his five fingers.

A huge, hemispherical space radiating a ghostly blue light instantly opened up, like an inverted giant transparent bowl, instantly enveloping everyone in front of the research institute—the Marines, the Straw Hat crew, and the children.

In his own space, he is the absolute master.

Luo simply flicked his finger upwards, accompanied by a deafening roar that shook the earth.

A massive naval warship anchored in the harbor was inexplicably uprooted, defying the laws of gravity, and floated lightly in mid-air, casting a large shadow.

Immediately afterwards, Rona's cold gaze locked onto the Straw Hat crew, who were trying to escape with the children.

He twitched his fingertips, preparing to activate his spatial displacement ability to forcibly intercept them.

At this critical moment.

Standing at the back of the crowd, Sanji keenly sensed a strange power of rules surging within that blue space.

Once locked onto by this force, the consequences would be unimaginable.

Without time to explain, Sanji suddenly turned around and roared:

"Sorry, Nami! Everyone, hold on!"

Sanji exerted force with his feet, and his leather shoes created a visible sonic boom on the ground.

He transformed into a black afterimage, his legs kicking out in rapid succession like a phantom.

With precise force, he kicked Nami, Chopper, Usopp, Franky, and the other large children out of the blue glowing boundary of the "ROOM" like a football!

"Ouch!"

"It hurts, it hurts!"

Everyone flew out of the light barrier like cannonballs, landing on their backsides in the air.

However, because Sanji controlled his strength perfectly, everyone escaped Law's spatial control unharmed.

After doing all this, Sanji stood alone at the edge of the blue space, lit a cigarette, and took a deep drag.

Then, he put his hands in his pockets and stared coldly at Luo in front of him:

"Long time no see, Navy."

"And... Trafalgar Law."

It was astonishing to see such a swift reaction at the critical moment.

A clear look of shock flashed in Law's eyes at the sight of the blond chef who could safely send all his companions out of the space before he could even activate his own ability.

The Straw Hat crew's strength seems to have made a qualitative leap compared to when they were in the Sabaody Archipelago two years ago.

Smoker was enveloped in thick white smoke, his ten-handed sword pointing directly at Sanji:

"Black Leg Sanji... Where is your captain, Straw Hat Luffy?"

……

The other side of Punk Hazard.

Luffy, Zoro, Victor, and Robin were leisurely riding on the back of the centaur Teabeard.

They traversed through areas ravaged by thunderstorms and fog, arriving at a desolate ruin behind the research institute.

Here, after some searching, they finally found the upper body to which the "lower body" belonged.

With Luffy's enthusiastic help, and amidst a flurry of fumbling, the two body parts were finally joined together seamlessly.

The samurai suddenly opened his eyes, took a deep breath, and stretched his entire body.

He clasped his hands together and bowed deeply to everyone in gratitude, introducing himself as "Kin'emon the Foxfire," a samurai from Wano Country, a country that had closed itself off from the latter half of the Grand Line.

Although Kin'emon's body was pieced back together and he was successfully rescued, he still looked shaken and his forehead was covered in cold sweat.

He abruptly drew his katana from his waist, his eyes scanning the dense poisonous fog around him with the alertness of a startled bird. He then solemnly warned Luffy and the others:

"My benefactors, please be very careful!"

"On this island filled with poisonous gas, lurks an extremely terrifying Shichibukai!"

"My body was instantly cleaved apart by his bizarre, sorcerous spatial sword technique, which was like sorcery, without me even having a chance to fight back!"

Upon hearing Kin'emon's vivid and terrifying description, Luffy showed no fear or hesitation whatsoever.

Instead, he pressed down on his straw hat, his eyes shining, and grinned with an incredibly excited and radiant smile:

"Sorcery? A spatial sword technique that can slice a person in half and still not kill them?"

"Hahaha, this is interesting!"

"I really want to see it!"
