Simultaneous Transmigration: Why is it all One Piece world?

Ace looked at him with suspicion. "You have money? The money you stole from Kaido may be a lot, but compared to the Revolutionary Army's massive organization, that little bit of money wouldn't even be enough to fill a tooth gap."

Nock smiled mysteriously. "Of course, I may not have any money right now, but I know where there's plenty of money!"

"So, Sabo?" Nok extended his hand, waiting for a response. "Want to go?"

Sabo looked at his hand, then at Ace's face, which was filled with "say yes, say yes, say yes," and remained silent for a few seconds. Just as he was about to speak, a whooshing sound suddenly came from afar, as if something was tearing through the air at an extremely fast speed, getting louder and louder as it approached.

Everyone turned their heads at the same time.

A giant bear paw print appeared out of thin air on the beach not far away, and the sand was blown away by the shock wave, raising a cloud of golden dust.

As the dust settled, two figures, one large and one small, slowly stood up from the center of the palm print; they were none other than the bear father and daughter.

Bonnie peeked out from his arms, her pink hair tousled by the sea breeze, her little face still showing the excitement of being launched.

"Daddy! That was so much fun! Let's do it again!"

Big Bear glanced down at her, a slight smile playing on his lips, but didn't reply.

"Have you gathered all the medicine?"

The bear nodded.

"I've already told you how the medicine is made, all that's left is time. Now, please do me my first favor."

"What is it?"

"Infiltrate Punk Hazard, hijack Vegapunk!"

...

New World Seas, Punk Hazard, also known as the Bank Exclusion Zone.

This is the Navy's research base, and it also houses some prisoners from the World Government. In 1539, four years before the Straw Hat crew landed on the island, M. Caesar Clown, but more people prefer to call him Scum, deliberately caused an experimental accident that released a large amount of poison gas onto the island, turning the entire island into a dead island.

A year later, M. Caesar Clown returned to the island after escaping the prison ship, dispelled the toxic substances on the island, and began using the island's prisoners to conduct his heinous experiments again. Another year later, after the Marineford War, Marine Admirals Akainu and Aokiji fought a ten-day, ten-night battle in the Bank Zone for the position of Fleet Admiral. Akainu emerged victorious, causing a drastic climate change in the Bank Zone, transforming it into the terrifying Ice and Fire Island.

Now, Nok and his team are stuck at the point in time when the Caesar experiment accident occurred.

Nok wasn't in a hurry at first, and he didn't care even if Punk Hazard was blown up, because his original target wasn't Vegapunk at all, but Caesar and the artificial Blue Dragon Fruit left on the island!

Although Caesar is not as good as Vegapunk, he is still a research talent. Based on the "bloodline factor" discovered by Vegapunk, he also developed artificial Devil Fruit technology. Although it is very crude and has great side effects, the user cannot gain the power 100%. Once the user fails, he will lose all expressions except for the Nika smile.

But it is still usable.

But things are different now!

Because of Nok, I've become stronger!

They even brought in several skilled fighters. Kizaru, who was previously no match for them, now seems to be able to fight them!?

What else is there to say?

Just do it!

...

Inside the Bank Restricted Area, the air was filled with a pungent chemical odor, mixed with the salty smell of the sea, making people feel very uncomfortable.

The weather was unusually nice, but the sunlight, filtering through the gaps in the clouds, fell on the unfeeling buildings without bringing any warmth.

In the laboratory, Vegapunk stood there, his brow furrowed on his high forehead.

Before him stood a man with long, pointed, light purple hair that seemed to float in the air as gas.

Caesar sat on the lab table with his legs crossed, fiddling with a test tube in his hand, a very unsettling smile on his face.

"Caesar, I must warn you again. Your experiments have crossed the line." Even the usually amiable old man's tone became serious when facing this guy. "The Navy has halted your 'Slime' project, and you should know the reasons very well."

Caesar's smile deepened. "Afraid of harming innocent people? Whoosh, whoosh, whoosh..." He scoffed. "Those fools and idiots deserve to die. Scientific progress always requires some sacrifices; that's noble science! Vegapunk!"

Vegapunk's eyes turned cold instantly. "Science is for the benefit of humanity, not for killing! You evil bastard, what do you take life for?!"

"Different paths, same destination." Caesar floated in front of Vegapunk, spreading his hands. "Vegapunk, you're too naive. This world doesn't need kindness, it only needs power, and I am creating power!"

Vegapunk paused for a moment, then issued his ultimatum: "This is the final warning, Caesar. If you continue, I will personally petition the Navy to terminate all your experiments and have you arrested!"

Caesar's smile froze for a moment, then he shrugged. "Whoosh whoosh whoosh whoosh... whatever you want."

Vegapunk said nothing more, turned and walked out of the laboratory. Behind him, Caesar watched his retreating figure, a sinister smile slowly spreading across his face.

Stop the experiment? That's impossible!

He walked to the window, looked at the gray and black buildings outside, and was about to say something when he suddenly frowned.

fog.

Dense fog.

I don't know when it started, but thick fog began to rise from the sea, covering everything like a giant white quilt, enveloping the entire Punk Hazard.

Visibility dropped sharply, and the gray-black buildings became indistinct in the fog, like rows of silent tombstones.

"Is it foggy?" Caesar muttered, not paying much attention.

In this new world, anything can happen.

Vegapunk walked out of the laboratory and noticed the fog. He glanced up at it but didn't think much of it and continued walking towards his research area.

On the beach, a man in a yellow suit lay on a beach chair, sunglasses perched on his nose, hands behind his head, one leg crossed and the other draped over the ground. He looked languid, like an old cat that had sunbathed enough, utterly relaxed.

It's none other than Kizaru Borsalino!

Admiral of the Navy Headquarters and Commander-in-Chief of the Science Unit!

But when the thick fog rolled in, he immediately sensed that something was wrong.

Borsalino opened his eyes instantly, his previously lazy gaze turning wary.

He activated his full Observation Haki, but found nothing unusual. He frowned, and his figure transformed into a golden light, instantly disappearing from the spot.

Vegapunk was still conducting his experiment when Kizaru suddenly appeared beside him.

"What happened, Povassalino?"

Seeing that Vegapunk seemed completely unaffected, Kizaru relaxed his expression.

"No, it's nothing."
