The year is 1484 by the Sea Calendar, the year of the God Valley War.
The New World.
Under a clear blue sky, a merchant ship sailed across the calm sea.
In a cramped crew cabin on the middle deck, Raiver Sky woke up in his bunk.
This was his third day since transmigrating into the world of One Piece.
To survive, he had no choice but to do odd jobs aboard the merchant ship.
In this perilous world, without talent, without a cheat system, and without a Devil Fruit, becoming stronger was easier said than done.
Just as Raiver was staring at the ceiling in despair, a mechanical voice echoed in his mind:
"Ding! System loading... Loading complete!"
"You have received a Newbie Gift Pack. Would you like to open it?"
This notification was like a beacon of hope, instantly lifting Raiver's spirits.
Without hesitation, he mentally shouted: "Open!"
"Congratulations! You have obtained the Space Fruit and a Body Enhancement Card!"
Along with the prompt, two streams of information flooded his consciousness.
[Space Fruit] A Paramecia-type Devil Fruit. The user can perceive and manipulate forces and space!
[Body Enhancement Card] Upon use, the body will receive a hundredfold enhancement (including but not limited to: organs, tissues, cells, etc.)!
"Excellent!" Raiver's heart raced. Without a moment's delay, he mentally commanded:
"Use the Body Enhancement Card!"
The next instant, a surge of energy, like a wave of heat, erupted from the deepest parts of his body, coursing through his limbs and entire being!
"Crack... Pop..."
His bones crackled and popped, muscle fibers bulged and restructured.
His physique visibly grew taller and more muscular, his once well-fitting coarse clothes instantly tearing apart, reduced to shreds hanging from his body.
In the blink of an eye, Raiver's height skyrocketed to 305 centimeters. (As tall as Doflamingo)
But this was merely the external change.
A more profound transformation occurred internally.
Raiver felt an unprecedented vitality surging through him, as if he had boundless strength.
He subconsciously clenched his fist, the air compressing with a faint whimper.
He sensed that he could effortlessly lift hundreds of tons, sprint at supersonic speeds at full power, and that the density of his skin and bones had increased dramatically, their hardness comparable to steel.
However, the most extraordinary aspect of this hundredfold enhancement was the exponential qualitative change at the cellular level!
His cell division and regeneration capabilities were enhanced to the extreme.
Even severed limbs could regenerate within seconds, and vital organs like the brain and heart could rapidly reassemble if destroyed.
Theoretically, as long as a single cell survived and absorbed sufficient energy, his body could fully regenerate from it!
This was, in biological terms, a near-conceptual "immortal body"!
Simultaneously, his cellular repair abilities reached their peak.
Not only could they precisely repair daily damage and aging cells, but they could even reverse the shortening of telomeres, eradicating aging at its root, achieving true immortality and eternal youth!
"This... this is just too overpowered!" Feeling the earth-shattering changes within him, Raiver was both shocked and ecstatic, unable to hold back a soft exclamation of awe.
Suppressing his excitement, he focused his mind, and a strange fruit appeared in his hand—deep azure in color, covered in spiral patterns, and shaped remarkably like a dragon fruit.
It was the [Space Fruit].
Recalling the descriptions of how unpalatable Devil Fruits were, he frowned, steeled himself, and took a bite—
Huh?
Instead of the nauseating taste he had expected, a burst of refreshing sweetness and fragrance exploded in his mouth, transforming into a peculiar warm current that flowed down his throat.
Youth has no price; the fruit melted in his mouth!
At the same time, he felt a miraculous ability resonating with space awaken within him.
"I need to find a place to test this fruit's ability…" Raiver Sky was eager to try.
Whoosh—BOOM!!!
Just then, an ear-splitting roar erupted from outside the ship, accompanied by the sound of splintering wood.
The entire merchant vessel lurched violently and tilted!
On the deck, objects clattered and people screamed in terror.
"Trouble! Pirates are attacking!"
"Look at that flag! It's… it's the Rocks Pirates!"
"Rocks?! That monster pirate crew, the strongest in the New World? We're done for! We're dead!"
"Run! Get out of here!"
The deck descended into chaos as crew members scrambled around like headless flies.
The merchant ship captain stared in despair at the pirate vessel blocking their path and the flag fluttering above it.
On the pirate ship, a group of ferocious-looking, menacing pirates brandished swords and flintlocks, roaring with bloodthirsty laughter.
"Hahaha! Another fat sheep!"
"Brothers, strip them clean!"
"Hehehe… let me take the lead!"
A burly pirate grinned viciously, raised his broadsword, and leaped from the pirate ship, slashing down toward the panicked crew on the merchant vessel's deck.
Even the lowest-ranking member of the Rocks Pirates was no ordinary foe—this single strike was enough to send several people flying.
At the critical moment!
Hum—!!!
A strange, soft sound echoed, as if space itself had been plucked.
An invisible yet powerful repulsive force field erupted out of nowhere, slamming into the pirate still mid-air like an unseen wall.
"Thud—"
Amid the sound of cracking bones, the pirate, without even understanding what had happened, was sent flying backward as if hit by a high-speed train.
Every bone in his body shattered under the impact, and he crashed into the distant sea like a lump of mud.
In the next instant, everyone saw ripples form in the air like water waves, followed by a tall, upright figure materializing out of thin air at the ship's bow.
It was a young man, seemingly under twenty, with black hair, crimson eyes, and a cold, stern expression.
He wore a black trench coat open at the chest, exuding an overwhelming, suffocating aura.
[Space Repulsion]—manipulating space to generate repulsive force!
"Wh-what just happened?!"
"That pirate… is he dead?"
"It's him! He saved us!"
The crew, overjoyed at their narrow escape, stared at Raiver Sky as if he were a divine savior.
Raiver Sky raised an eyebrow. "You… are from the Rocks Pirates?"
"Where did this brat come from! How dare you kill our man!" On the pirate ship's deck, the pirate leader roared with laughter and commanded:
"Brothers, open fire! Shoot this pretentious brat full of holes!"
Bang bang bang bang bang—!
A barrage of gunfire erupted as countless bullets flew toward their target.
Raiver Sky remained expressionless, neither dodging nor evading.
Just as the bullets were about to strike him, his body seemed to lose its physical form, abruptly turning transparent as if merging with space.
Whoosh whoosh whoosh—!
In the next instant, the dense volley of bullets passed through his ethereal form, all striking the deck and leaving behind a dense pattern of bullet holes.
[Voidification] – Temporarily merging the body with space, entering a transparent, ethereal state to evade all attacks!
"What?! That's impossible!"
"The bullets went right through him! What the hell?!"
"Is he... human or a ghost?!"
The pirates who witnessed this scene were dumbfounded, their eyes nearly popping out of their sockets.
Clearly, this group of pirates had unfortunately become Raiver Sky's test subjects.
Raiver Sky slowly raised his right hand, aimed it at the pirates on the ship ahead, and gently clenched his fist.
"Space Imprisonment!"
Hum—!
An invisible force field instantly expanded, locking all the pirates on the deck in place.
In the next moment, time seemed to stand still.
Every pirate was frozen where they stood.
One pirate, who had even leaped into the air with both feet off the ground, was now suspended mid-air like an insect trapped in amber.
Witnessing this, Newton's coffin lid would have been struggling to stay shut.
[Space Imprisonment] – Solidifies the space around the target, creating an absolute confinement field, rendering them unable to move or act!
Just as Raiver Sky prepared to deal with the frozen pirates, a mechanical voice echoed in his mind once more:
"Ding! Limited-time mission: Choose a faction to join—[Marine Headquarters] or [Rocks Pirates]!
Mission reward: Supreme Grade Sword - Black Dragon, Advanced Swordsman Sword Skill!"
Without the slightest hesitation, Raiver Sky made his choice immediately: "Join the Rocks Pirates!"
Since he had arrived in this sea where freedom and power were pursued, why bind himself with rules and restrictions?
Following his desires, indulging in vengeance and pleasure, seizing everything he wanted with strength—this was the path he yearned for!
"Ding! Congratulations, you have obtained the Supreme Grade Sword - Black Dragon and Advanced Swordsman Sword Skill!"
A flood of techniques and experience—covering precise sword handling, slashing, and parrying—merged into his mind.
Simultaneously, a long sword appeared at his waist, its blade entirely black and entwined with dragon patterns.
"Ding! Mission: Become an executive of the Rocks Pirates!
Mission reward: Advanced Armament Haki!"
By this time, the pirates trapped by Space Imprisonment finally snapped out of their terror.
Though their bodies remained immobilized, they could still speak.
"Damn it! What's happening? Why can't I move?!"
"It's that monster! He must be a Devil Fruit user!"
"Let us go!"
Raiver Sky's eyes narrowed.
A repulsive force emerged once more, but this time, instead of pushing away, it formed an invisible shockwave that passed through the body of every imprisoned pirate.
"Argh—!"
The repulsive force tore through the pirates' bodies, instantly shattering their bones and destroying their internal organs.
The moment Raiver Sky released the Space Imprisonment, the pirates collapsed like boneless sludge, one after another, becoming lifeless corpses.
Only the pirate captain remained on the entire ship.
Raiver Sky's gaze fixed on him as he raised his right hand, aiming it at the captain from a distance.
The next instant, an irresistible force of attraction instantly acted upon the pirate leader, lifting him into the air like a marionette and swiftly pulling him toward Raiver Sky.
[Space Attraction] Manipulating space to generate gravitational force!
"Cough... Don't kill me! I beg you! Spare my life!"
The pirate leader, his neck clamped in Raiver Sky's iron-like grip, turned red from lack of oxygen. His legs kicked helplessly in the air as he pleaded incoherently:
"I'll give you all the treasures on the ship! Everything!"
Raiver Sky sneered coldly, "Want to live? Fine. Take me to the Rocks Pirates' main base."
With that, he vanished from the spot, carrying the pirate leader like a chick.
When they reappeared, they were already on the deck of the pirate ship. He casually tossed the pirate leader at his feet.
Clutching his neck, now marked with red bruises, the pirate leader looked up, still shaken, and asked in a trembling, cautious voice:
"Who are you, really? What do you want at our main base?"
