Simultaneous Transmigration: Why is it all One Piece world?

Anorectal space.

In the void of darkness and white, three figures sat cross-legged.

Navy Nock still carried the fatigue of training; life in the elite training camp was far from easy. Every day involved running laps with weights, swimming in the waves, practicing the Six Styles, and real combat simulations. That old man Zephyr never held back. But at this moment, his aura was much calmer than before. Shave, Moonwalk, and Storm Kick had become second nature to him. He had mastered Armament Haki thanks to Nock's sharing, and his Observation Haki was beginning to take shape.

Fishman Nok sat cross-legged on the other side, his arms crossed. Beneath his blue skin, his muscles were smooth and powerful. During the days he had been training in Fishman Karate with Jinbe, his understanding of "the breath of the ocean" had deepened. The feeling of being one with the seawater had also deepened his understanding of Haki.

Swordsman Nock, meanwhile, was examining the knife in his hand.

Four months have passed since he killed Fukurokuju. His injuries have long since healed, and he has been busy clipping Orochi's wings. Orochi's control over the Flower Capital has weakened to the extreme. Soon, he will be sidelined, and then it will be time for reckoning.

The reason the three of them are gathered here today is that the energy generated by their growing reputation over this period has caused another Noc to be anchored in the space.

Navy Nock spoke first, his tone tinged with emotion: "Half a year has passed, and finally another one has arrived."

Fishman Nok crossed his arms and grinned, "It hasn't been easy. I've been training like a dead fish with Jinbe every day, and I still don't have enough energy?"

"That's called training, how can it increase prestige? I killed Fukurokuju and countless of Orochi's men to raise enough prestige."

"I also fight those fishmongers to increase my reputation on Fishman Island, you know!"

Navy Knock nodded: "Me too. I'm now a genius in the training camp, second only to those two monsters, Kizaru and Akainu. My reputation should have increased a lot because of that."

They were talking, and soon all three of them turned their heads at the same time.

In the depths of darkness, fog churns.

It was more intense than ever before.

"Here they come." Navy Nock stood up.

Fishman Nok and Swordsman Nok also stood up, their gazes fixed on the churning fog.

The fog dissipated.

A figure emerged from the darkness.

He was a young man wearing a white lab coat, with glasses perched on his nose. He held a strange little device in his hand, which was flashing with blue lights. His hair was messy, as if he hadn't taken care of it in a long time, but his eyes shone with a look that was completely different from the combat-type Nocs.

People generally prefer to call it clear.

He stepped out of the fog and stared blankly at the three faces in front of him that looked exactly like his own.

Then he pushed up his glasses.

"So..." he began, his voice tinged with uncertainty, "you are all me? Fellow transmigrators?"

Navy Knok nodded, looking him up and down, his gaze landing on the white lab coat, which had an unfamiliar logo embroidered on the chest, resembling a combination of an open book and gears.

"You are..." He paused, "a researcher?"

Researcher Nock nodded, looked down at the device in his hand, and smiled.

"To be precise, I was a researcher at 'Science Future Island,'" he said. "I was doing research on Devil Fruits there, and then today I took a nap, and when I woke up..."

He looked around.

"...We've arrived here."

Nok the fishman stepped forward, circled him once, and suddenly grinned.

"Interesting, this time it's a smart Nocturne?"

Researcher Nock adjusted his glasses and looked back at him.

"We complement each other, by the way, I've transmigrated to the One Piece world, what about you?"

"Me too!"

Navy Nok grinned, but his words stunned Researcher Nok, who then focused his attention on Fishman Nok.

"You...are all?"

"Let's cut the chit-chat and just share, it'll save us a lot of trouble!"

As he spoke, swordsman Nok stepped forward and slapped researcher Nok on the body.

The next moment, memories began to be shared.

The next moment, the memory sharing was complete.

Researcher Nock took a step back in surprise, but swordsman Nock was even more surprised than him.

"You're not just a researcher, you're... Nok from the future!"

Upon hearing this, both Navy Nok and Fishman Nok were taken aback and stepped forward to share their memories.

It turns out that this researcher, Nock, comes from 500 years in the One Piece world.

...

2026 in the Haiyuan calendar.

Five hundred years after Luffy set sail.

The man in the straw hat and his companions have long become legends. They overthrew the tyrannical world government of Im, ending eight hundred years of dark rule and allowing the sun to shine into this sea once more.

The world experienced a brief period of peace.

Twenty years, thirty years, fifty years...

however--

What has been will be again, what has been done will be done again.

Once a new world government is established, once a new center of power is formed, once the boulder of desire begins to roll down the mountain—it will be impossible to stop it.

The dragon slayer of yesteryear has become the new dragon.

A new world government, new Celestial Dragons, a new system of slavery, except this time, it's a different group of people being trampled underfoot.

Conflict has resurfaced.

The war reignited.

Five hundred years later, the world has split into countless separatist forces, fighting each other endlessly.

Noc was born in one of these factions—the Dawn District.

Nok, a medium-sized technological separatist force, was selected to join the research institute as a researcher because of his time travel. He displayed extraordinary intelligence and keen perception of mechanics and energy from a young age.

His research focuses on Devil Fruits.

To be precise, it's about the energy conversion mechanism of Devil Fruits, and how to eat multiple Devil Fruits at the same time without them exploding.

Memories flow to this point.

The four looked at each other, speechless for a long time.

After a long silence, the fishman Nok spoke, his voice tinged with helplessness: "Five hundred years later, it's still the same."

Future Knok pushed up his glasses and gave a wry smile.

"There's nothing new under the sun," he said. "Power corrupts everyone, including former rebels. Nika and Luffy's generation were alright, but after they died, those who succeeded them... ha."

He didn't finish his sentence, but his meaning was clear.

Navy Nock was silent for a moment, then suddenly asked, "What about technology? Five hundred years have passed, how far has technology progressed?"

Actually, these questions are already in my memories, but the vast amount of memory requires searching through, so it's better to just ask directly.

Future Nock's eyes lit up.

"There has been progress, but also losses due to the war."

He raised the device in his hand, the small instrument that flashed blue light.

"Many of Vegapunk's technologies have been lost. Artificial Devil Fruits, Fallen Angels, the Mother Spark... In those years of war, knowledge died faster than people."

He paused.

"But there have also been new breakthroughs."
