One Piece: System User In The World Of Pirates

"Not good, Moria-sama, get out of the way!"

Absalom shouted anxiously as he saw Kaelen's thunderous attack approaching.

But Moria, who had already lost his sanity, ignored the warning as if he hadn't heard it.

In truth, even if Moriah had been fully conscious, there was no time to dodge. He could only brace for the incoming strike.

Boom!

A heavy impact landed squarely on Moriah's head, Kaelen's fist charged with the power of his Shock Fruit.

It was like a primordial sacred mountain crashing down with overwhelming force.

After receiving the blow, Moria's scarlet eyes briefly regained some light.

But in the next instant, they filled with overwhelming fear.

"No…"

With a terrified cry, Moria's massive body plunged into the sea.

Like a deflated balloon, he rapidly shrank from nearly twenty meters back to his normal size before sinking quickly to the ocean floor.

Submerged, Moria's Devil Fruit power vanished, and the bats that had carried Absalom dispersed instantly.

"No, Moria-sama…"

Before Absalom could finish, he too fell into the water, following Moria's descent.

"Though powerful, these abilities have severe weaknesses. Seawater, the ocean floor, and Haki all suppress Devil Fruit powers."

"But I'm part of the system; I don't have to be limited by such things."

With that thought, Kaelen dived after them, moving through the water like a sleek dragon in pursuit.

He first grabbed Absalom, then the sinking Moria.

"Phew…"

Caught by Kaelen, both Moria and Absalom's eyes filled with gratitude, believing they had been saved.

They opened their mouths to speak but instead swallowed seawater, choking as tears streamed down their faces.

"Looks like there's been a bit of a misunderstanding."

Kaelen's lips curled into a strange smile.

Before the two could react, Kaelen clasped Absalom's neck with one hand, and with a burst of power, crushed it.

[Ding, congratulations to the host for acquiring the Stealth Fruit ability from Abu Salom's corpse…]

Ignoring the system notification in his mind, Kaelen discarded Absalom's body and seized Moria by the neck with both hands.

Once in the sea, even the strongest become vulnerable, like helpless shrimp with no means of resistance.

Ordinary people can be easily killed in such a state.

"Goo-goo, aa, ab…"

With a crack, Moria's eyes widened, his mouth opened in shock as his slender neck twisted painfully.

For a moment, his vitality flared, and his massive body thrashed desperately.

Kaelen's arms ached from the struggle, but after several moments, Moria's resistance weakened, his limbs convulsing uncontrollably.

"These pirates are tenacious, reaching this level and still refusing to die."

There was no system prompt this time, but Kaelen tightened his grip again.

The pirate world was full of strange powers and enhanced vitality.

Even ordinary people had stronger physiques and endurance than those from the world Kaelen came from.

Monsters like Whitebeard, riddled with bullets and slashes, still held on for a while before finally dying.

Their vitality was terrifying.

[Ding, congratulations to the host for acquiring the Shadow Fruit ability from Moriah's corpse, along with the experience package for developing Little Oz's shadow…]

After a few more moments, Kaelen finally relaxed his grip and let Moriah's body sink.

Boom!

The ocean surface broke as Kaelen transformed into flames, flying back to the sailboat in an instant.

Deep below, the scent of blood from the two bodies attracted several large carnivorous fish.

They tore the bodies apart, quickly devouring them.

Meanwhile, the Great Voyage reached a deserted island.

The island was in ruins, with only the castle in the center still standing.

Suddenly, in a Gothic-style room inside the castle, a very cute pink-haired girl looked up into the void.

"Moria-sama…"

...

"If you had the Stealth Fruit, what would you want to do most?"

Kaelen gazed up at the sky, contemplating the question with a pensive expression.

He was a man of integrity, a gentleman who would never step foot in a women's bathhouse—impossible for his lifetime...

"If I combined it with the Silent Fruit, the ability to vanish completely, it would be perfect. No worries about being discovered while spying."

Unconsciously, a flawless plan formed in Kaelen's mind.

He swore it was not from his own heart.

"It must be a demon's temptation. My power is improving too fast; I need to calm my mind."

Kaelen looked like a high monk, face inscrutable, but the smile at the corner of his lips betrayed him.

The gentle sea breeze blew as the sailboat soon sailed away from the battle zone.

"Hey, don't come out yet. Stay underwater longer or risk becoming the eighth king of the millennium!"

Kaelen glanced at the sea below with a mocking laugh.

Just then, a head suddenly surfaced from the empty sea.

At first glance, it looked frightening.

"Hahaha, your perception is keen little brother. The old man just arrived and was discovered by you already."
