Simultaneous Transmigration: Why is it all One Piece world?

The year is 1509 in the Sea Calendar, 29 years before Luffy set sail, in the timeline of Navy Nok.

Naval Headquarters, Marineford.

The vast bay resembles the open mouth of a giant beast, swallowing and spitting out warships coming and going.

An intact warship escorted another battered warship slowly into the harbor. The ship still bore the marks of battle: charred planks, broken railings, and canvas riddled with bullet holes.

The warship docked.

As the gangway was lowered, squads of marines began to disembark in an orderly fashion. Stretchers carrying the wounded were carried down, and fallen heroes were draped in flags and escorted away. Survivors lined up on the dock to receive inspection.

On another warship, a middle-aged man with a mustache, a lieutenant general who had come to provide support a month earlier, strode down the gangway and walked toward them.

"You've had a good time." He nodded to the officer who greeted him, his gaze sweeping across the ranks, searching for something.

But soon he discovered that the person he was looking for was not in the queue.

"Where is Mrs. Saori?" he asked.

Just as the officer next to him was about to answer, he saw a gentle figure walk out of the cabin.

Saori, the wife of General Zephyr, is nearly forty years old but still retains the charm of her youth. She is holding the hand of an eleven or twelve-year-old girl with two braids, who is peeking out at the dock.

"Madam," the lieutenant general greeted her gently, "General Zephyr is on his way back. Please come with me."

Saori nodded, but did not take a step.

Her gaze passed over the lieutenant general and landed on the sea beside the warship.

"Please wait a moment," she said.

The lieutenant general was taken aback.

Saori didn't explain; she just quietly looked at the sea.

Some officers looked at each other, wondering what they were waiting for.

One minute.

Two minutes.

The sea was as calm as a mirror, with only ripples from a gentle breeze.

finally--

Whoosh!

A figure burst out of the water!

Nock burst out of the sea, shirtless and soaking wet, his strong, powerful muscles glistening in the sunlight.

He was panting heavily, but he was grinning.

"Cool!"

Everyone on the dock was stunned.

Is the general's wife waiting for someone?

Saori's lips curled up slightly.

The girl jumped up excitedly and waved at Nok: "Brother Nok! Over here!"

Nock looked up and was taken aback when he saw the scene on the dock.

Ever since he acquired the abilities of the fishman Nok, he has become addicted to this feeling.

Swimming in the deep sea, resisting pressure, while training and thinking about the comics from his past life. In Dragon Ball, Goku trains using gravity. Would this count as "seawater gravity training"?

I got so engrossed in practicing that I forgot the time.

I didn't expect that once I got ashore, we would already be there?

"Cough." Nock coughed lightly, swam over from the sea, and climbed onto the dock along the ship's side.

Water droplets slid off the muscles and pooled on the ground.

He walked up to Saori, scratched his head, and said, "Madam, why didn't you go first? You didn't need to wait for me."

Saori looked at him with tender eyes.

"You saved us," she said. "Wait a minute, it's nothing."

The lieutenant general with a mustache standing next to him looked Knok up and down, his gaze somewhat complicated.

"Are you Nock?" he asked.

"Yes." Nock nodded.

The lieutenant general was silent for two seconds, then suddenly laughed.

"Interesting," he said. "Let's go."

Nock paused, then glanced at Saori.

Saori nodded gently and took the girl's hand.

"Let's go."

A gentle sea breeze caressed the pier.

Nok followed behind Saori, taking steps forward.

Marineford.

He finally arrived.

......

at the same time.

In the deep sea.

In the waters Nok had just swum through, the carcass of a sea king was slowly sinking.

He took a punch head-on, and his skull shattered.

If anyone could see this, they would probably find it unbelievable.

A human fought and killed a sea king with his bare hands in the deep sea.

Unfortunately, no one saw it.

The remains continued to sink, descending into the deep abyss.

...

Office of a general from the Warring States period.

The files were piled up like a mountain.

Zhan Guo sat behind his desk, holding a list in his hand, his brows slightly furrowed.

A goat was slowly chewing on a stack of documents on the table, the crunching sound particularly clear in the quiet office.

Elite training program.

He glanced again at the first two names on the list—

Borsalino.

Sakassky.

Two monstrous newcomers.

No, to be precise, they were two "problem trainees" who were already giving the instructors a headache even before they officially joined the team. One was so lazy that people suspected he might fall asleep at any moment, and the other was so radical that people worried he might tear down the training grounds. But their strength... Sengoku had to admit that the Navy hadn't seen any candidates of this caliber in many years.

That's why this elite training program exists.

They were specially tailored for them and personally guided by the highest combat power of the headquarters, with the goal of honing them into the Navy's sharpest blade as soon as possible.

And now, another name is going to be added to the list.

Nock.

Sengoku put down the list and picked up another report.

This is a detailed record of that encounter: the Tiger Roar Pirates attacked, the escort ship was damaged, Vice Admiral Pang was ambushed and lost an arm, Major Nock single-handedly held off Tiger Roar Baccarat, was knocked into the sea but returned to the battlefield, and finally fought back and killed him.

The report concluded with a photograph of Baccarat's headless body.

Sengoku stared at that photo for a long time.

A Zoan-type Devil Fruit user with a bounty of 5360 million Berries, he has been on the Grand Line for twenty years and is already considered a well-known pirate in the current timeline. He is definitely not someone that an ordinary major can deal with.

Nock won.

Although it was tough, and I almost died, we did win.

Moreover, he saved Zephyr's wife and daughter.

Zhan Guo put down the report, leaned back in his chair, and let out a long breath.

"Lieutenant General Pang..." he murmured, "What a pity."

As for Nok, he's also a promising talent.

Sengoku's lips twitched slightly, revealing a smile that even he himself didn't realize.

It's thriving!

There was a knock on the office door.

"Report!"

Sengoku put away his smile and resumed his serious expression.

"Come in."

The adjutant pushed open the door and saluted.

"Admiral Sengoku, Saori, the wife of Admiral Zephyr, has arrived at headquarters, accompanied by Lieutenant Commander Nock, a hero of this operation."

Sengoku nodded.

"After you've settled Nock in, come see me tomorrow morning."

"yes!"

The adjutant turned and left.

...

The dormitory area on the other side of the fortress.

Nock stood in a small single dormitory room, looking around—a bed, a table, a chair, and a wardrobe.

It couldn't be simpler.

But it's still much better than the hammocks on warships.

He placed the fine, jewel-encrusted sword, Huazhi, on the table and casually pulled up a chair to sit down.

Saori was picked up by Zephyr's adjutant. Before leaving, she held his hand and said a lot of things, such as "Get some rest," "Come find me if you need anything," and "Zephyr will thank you in person when he comes back."

The girl was reluctant to leave, clinging to his clothes and refusing to let go, until Saori finally coaxed her away.

Nock leaned back in his chair and closed his eyes.

Fishman Noc has already started training with Jinbe, and Swordsman Noc is also steadily progressing in mastering Armament Haki under Kyoshiro's tutelage.

He opened his eyes and looked out the window.

Tomorrow, I will go to see the Warring States period.

Elite training camp...

He clenched his fist.

We need to step up our efforts!
