Under One Person: The Sea Emperor Who Shattered Heaven and Earth

Under One Person: The Sea Emperor Who Shattered Heaven and Earth

Author: Forever Loves Ryougi Shiki

Synopsis: Jiang Zhen transmigrates into the world of "Under One Person" and awakens the "Tremor Fruit," emerging from the Shiliupu Wharf in Shanghai.

That year, Zhang Zhiwei had not yet reached the pinnacle of his career, while Wugensheng was enjoying life to the fullest.

Jiang Zhen, however, had already shattered the air with a single punch on the shores of Shanghai, establishing a rule: "Where I stand is justice; the sea I demarcate is a forbidden zone!"

Golden Light Mantra? Thunder Magic? Divine Spirit?

All is in vain before the tremors powerful enough to shatter space itself.

He once killed the Higa ninja with a single punch during the war of resistance against Japan, and he also forcibly banned the Demon City during the chaos of the Jia Shen year.

When he crossed the ocean and was crowned emperor on Nathan Island, the world's aircraft carrier fleets would tremble under the aftershocks of his fist.

From a lowly soldier in the Grand Canal to a world-renowned maritime emperor, Jiang Zhen tells the world: This era belongs to Jiang.

Chapter 1 What are you doing here?

Shanghai, 1935.

When Jiang Zhen opened his eyes, he was lying on the deck, which was covered in oil stains and smelled of salted fish.

"Where did I come from?" Jiang Zhen vaguely remembered working overtime when he suddenly felt sleepy and dozed off. When he opened his eyes again, he found his surroundings were wrong. "Did my bastard boss sell me out while I was sleeping?"

While Jiang Zhen was still in a daze, he happened to see a strangely shaped fruit next to him. The more he looked at it, the more familiar it seemed. "The Zhenzhen Fruit?"

"Could it be that...!"

Jiang Zhen picked it up; it didn't look like a plastic model. The thought that had been swirling in his mind made him unable to resist taking a bite.

"It smells like shit, but that's what makes it authentic! That's what makes it genuine!"

Jiang Zhen then felt the change in his body, that power.

"Hiss—it's genuine!"

Jiang Zhen tried to make a move, lightly touching the stone next to him with his fingertips.

hum!

The small stone emitted a piercing wail, and a crack appeared instantly. Jiang Zhen's index finger also felt a sharp pain, and fine beads of blood seeped from under his fingernail.

"No... this body is too weak, it's numb, what kind of ancient setting is this..."

Jiang Zhen gasped and quickly withdrew his hand.

It is indeed the Tremor-Tremor Fruit, but the Tremor-Tremor Fruit, no, almost all Devil Fruits, have requirements for physique. The higher the physique, the stronger the ability. Not to mention the Tremor-Tremor Fruit. Ignoring the injuries on the old Whitebeard, he is not one of those tanky characters in One Piece who can do sit-ups. With his weak body, he simply cannot withstand even a "full-force punch".

And now, most importantly, he is hungry, and the feeling of hunger is getting stronger and stronger, to the point that his vision is starting to go black.

"Oh no, my ambition for conquest..."

When Jiang Zhen woke up again, he found himself lying on a small bed, with a faint salty taste still lingering in his mouth.

"Young man, you're awake?" An old man walked in.

“I saw you collapsed by the riverbank, and your stomach was rumbling, so I picked you up and fed you some fish soup.”

Jiang Zhen quickly sat up and said, "Thank you, sir. I was so hungry that I fainted."

"That's perfect. The fish stew is ready too. Have some first. Everything will pass."

……

During the ensuing conversation, Jiang Zhen learned that he had indeed time-traveled to a world during the Republic of China era, specifically to Shanghai. He briefly told the old man that he and his family had come to Shanghai to beg for food, but they had encountered a shipwreck and were now all alone.

But ultimately lacking any acting talent, Jiang Zhen couldn't squeeze out a single tear for a long time.

The old man paused for a moment, then asked curiously, "Do all of you out-of-towners have the same story? I've heard this excuse at least ten times. The other day, Old Zhang next door brought back that from the sea, and last month too..."

Jiang Zhen sensed something was wrong. According to the normal procedure, the old man should have believed it by now and expressed deep sympathy. Most importantly, there should have been a beautiful granddaughter nearby who could also feel sorry for him and allow him to stay there for the time being.

But what the old man meant was, "I've saved you, and you've done a good deed. After this meal, you can go wherever you want. We don't have enough food to feed you. If you become successful in the future, just pay for today's meal."

Having understood what he meant, Jiang Zhen could only laugh awkwardly. After eating and drinking his fill, he thanked the old man again for his rescue and promised to repay the kindness in the future.

Jiang Zhen didn't rush off to explore the world. Instead, he wandered around until he arrived at a dock. Looking at the laborers around him, their backs tanned dark, silently carrying loads in the heavy rain, he resolutely walked towards the dock's recruitment office.

I was looking for a clerical job, but it turned out he couldn't write traditional Chinese characters, which was quite embarrassing.

"Name?" The foreman glanced at him sideways, a pipe dangling from his hand.

"Jiang Zhen".

Have you ever done manual labor?

"Capable," Jiang Zhen said succinctly. His height, which was significantly taller than others, did indeed give him the appearance of a northern man, although his complexion was somewhat sickly pale.

"Have you thought it through? Hard labor can kill people." The foreman sneered.

"I've thought it through. Just give me some food."

The days become blurred in the mechanical labor.

The Shiliupu Wharf is the lifeline of Shanghai, where countless raw silk, tea, and porcelain flow through every day. Jiang Zhen's daily task is to carry a 200-pound sack back and forth hundreds of times between the swaying gangplank and the steep embankment.

This kind of life would be torture for ordinary people, but for Jiang Zhen, it was the best. He could exercise his body and make money at the same time, which was a win-win situation.

He soon discovered that the power of the Tremor-Tremor Fruit wasn't just destructive. When he lowered the frequency to match the rhythm of his muscles, the slight vibrations could accelerate blood circulation, relieving lactic acid in his muscles like a top-of-the-line deep tissue therapy device.

Great. If things turn out to be really complicated in the future, and I can't make it in the world one day, I can always open a massage parlor.

Then, in the shadows of the dock, a strange man appeared.

While other laborers were exhausted and collapsed like mud after moving the goods, Jiang Zhen would always stay up late at night guarding those heavy iron mooring posts, or staring blankly at the rolling Huangpu River.

In fact, he was taking every opportunity to cultivate himself.

When the night is still and quiet, Jiang Zhen would strip shirtless and place his palms against the cast iron pillar by the river. He would carefully control the slightest vibration, letting it flow from his fingertips throughout his body.

"Squeak... squeak..."

That was the sound of bones being compressed. He was using the vibrations, like forging steel, to gradually solidify the density of his body.

During the first week, his palms were covered in blisters, a truly pitiful sight.

In the first month, a bluish-gray sheen appeared faintly beneath his skin, a sign of highly compressed muscle fibers.

By the third month, Jiang Zhen was already able to carry a 400-pound cargo box on the gangplank with ease and without any difficulty in breathing.

"Is Jiang Erlengzi some kind of naturally strong kid?" the foreman muttered to himself.

Until one late night, Jiang Zhen encountered some "abnormal" people at the entrance of the alley.

Two men in black short jackets were attacking an old man. The two men moved with incredible speed, and their palms seemed to glow with a faint green light.

"A martial arts master?"

"I knew it! If they can give me cheat codes, this definitely isn't some normal Republic of China era!"

Jiang Zhen, hiding behind a pile of firewood in the shadows, was somewhat surprised. He saw one of the men slam his palm against the wall, and the wall rapidly corroded and crumbled as if it had been splashed with sulfuric acid.

This completely defies common sense in physics.

"The 'martial arts' of this world seem a bit outrageous; they even have special effects," Jiang Zhen thought to himself. But he didn't dwell on it. After all, he already possessed the Tremor-Tremor Fruit, so it seemed plausible that others would practice some strange chemical poison techniques.

But he discovered that the moment the other party unleashed that "light," a clear "fluctuation" appeared in his perception.

From his "vibration perspective," that so-called extraordinary power was nothing more than energy of a specific frequency. If he wanted, he could easily disrupt the frequency of that energy with a single punch.

Jiang Zhen watched silently as the two men finished fighting and left. From beginning to end, neither of them noticed that there was a person crouching in the shadows a hundred paces away.

"Not enough. I don't know how deep the waters of this world are. I need to step up my physical fitness and develop my abilities," Jiang Zhen murmured, looking down at his arms.

He was still waiting, waiting for his body to become strong enough to withstand that real punch.

Half a year has passed in the blink of an eye.

In the autumn of 1935, the shadow of the Japanese army loomed over Shanghai. Some ronin, using the name of the Japanese Chamber of Commerce, began to run rampant at the Shiliupu Wharf.

That day, a merchant ship flying the Rising Sun flag docked.

Dozens of ronin with samurai swords at their waists rushed off the gangplank, driving away the dockworkers. One of them, the leader, had a cold look in his eyes and walked with his toes barely touching the ground; he was clearly a trained fighter.

"Go away!"

The leader of the ronin kicked over the rice bowl of an old laborer, which was the lifeblood of Old Wang, who had worked for Jiang Zhen at the dock.

Jiang Zhen was carrying a box of raw silk when he paused slightly.

"Damn it, if it were just ordinary thugs, I could put up with it, but not this kind of beast."

"After so much time and effort, it's time to take the first step."

"Pay up!" Jiang Zhen stopped and walked up to the ronin, his voice sounding particularly calm in the noisy dock.

"Huh?" The ronin leader seemed to have heard a joke, and slapped him across the face with his backhand, a cold force gathering in his palm. "You lowly laborer, die!"

The palm struck Jiang Zhen's chest. Amidst the terrified screams of those around him, Jiang Zhen did not dodge. He also wanted to test the extent of his hard training over the past six months.

He did a move he had practiced countless times—he gently shrugged his shoulders.

Om-!

It is a pure, extremely high-frequency vibration.

The moment the ronin's palm touched Jiang Zhen's shoulder, a frequency powerful enough to shatter steel rebounded instantly from the point of contact.

Click!

A crisp cracking sound.

The ronin leader's entire right arm, from his fingertips to his shoulder blade, was shattered into dozens of pieces in less than a second. He didn't even feel the pain; he just watched helplessly as his hand hung down like a sack full of pebbles.

"you……"

Just as the leader of the ronin was about to scream, Jiang Zhen took a step forward and kicked him into the river.

Clenching his right fist, he used the brute force he had honed over the past six months, combined with a low-frequency vibration, to smash it down on the solid bluestone embankment beneath his feet.

Boom! ...

The entire wooden gangway of the dock collapsed instantly, and the heavy ground undulated violently like waves. A dozen or so ronin were thrown into the air by this invisible shockwave and fell into the Huangpu River, where they were swept away by the surging water in the blink of an eye.
