Gu Changtian accidentally travels to the world of One Piece and is bound to the One-Punch Man Summoning System. In the One Piece world, he establishes the First Legion and continuously accumulates shock points.

Such a terrifying demon has crossed over into the world of One Piece. What will become of the One Piece world...?

"The Warring States period was terrifying; the First Legion members were all like monsters..."

Whitebeard: "Giants are the strongest men in the world..."

Redhead: "Oh no, my pride isn't working anymore..."

Garp: "Even my iron fist can't beat the First Legion..."

Kizaru: "No matter how much money you offer me, I won't fight the First Army..."

Kyle's third time traveling through time brings him to a world far more bizarre and dangerous than those of One Piece and Naruto. The painful experiences of his first two journeys, where he died in swords and kunai upon inheriting his memories, taught him this: if you're not strong enough, you die! Awakening his Nen ability at the age of seven, he possesses the power to turn everything around—the Book of the Unique World Resonance! When Gon needs strength to challenge Hisoka, Kyle extends an invitation: "Sign a contract. I'll grant you the opportunity to train in another world, and you'll grant me the power to reflect back." Thus, the Hunter world's strongest pirate group sets sail, and an organization more powerful than the Akatsuki in the Ninja World is born. But Kyle harbors a deepest secret: does this seemingly fair contract reflect the fruits of training, or does it reflect the fate of the contracted... themselves? As the bonds of the powerful from three worlds intertwine, what awaits them is the path to the highest...

When Kaido merged with the soul of an unlucky transmigrator, he learned that the world he was in was a manga, and that he was merely a stepping stone for Luffy, the so-called chosen one of destiny, to defeat him.

"What kind of bullshit is Wang Luffy, Chosen One, Joy Boy? I'm going to smash you all to pieces..."

'Ding, system loading...'

Kaido: "So this is the cheat code of that unfortunate transmigrator? It seems that after merging with that guy's memories, I not only know the direction of the plot, but I also have a cheat code to use..."

'Ding, system loading complete. You are not the host of this system. The system will automatically unbind you. Goodbye...'

Kaido: "Damn it..."

(Cheerful, cold-blooded, ruthless, bloodthirsty, ambitious. Kaido is the Kaido from the original work, but one who knows the plot; his personality won't change much.) (Completed novel: "One Piece, Me, Marco, Starting with the Marineford War")

[Change to single order + follow-up shipment + no system]

Starting from the East Blue Saga, the story will still follow the original plot after the main characters join the group. The main plot will not be changed, but each sub-saga will be appropriately changed according to the butterfly effect brought about by the main characters joining (most of the dialogues are written by myself and will not follow the original work).

Gan Yu's strength wasn't invincible at first; it gradually recovered later. However, she was always the strongest on the ship, but she wouldn't take action very often.

This story is lighthearted and tries to stay true to the style of the original work, with a fast pace that combines battles with everyday conversations.

P.S.: Two to three updates a day, the exact time is uncertain.

"Only domineering power can rise above everything else."

This is a famous saying by Kaido, the gold-medal lecturer of the Grand Line, known as "King of Beasts," and is regarded as a guiding principle by countless people.

But Roy did not agree with this.

"Then let me ask you—if there were a user who could analyze and collect all the Devil Fruit abilities, and was unaffected by Seastone and seawater, could he reach the pinnacle of this ocean with his Devil Fruit abilities?"

To prove his point, Roy took action.

...

Many years later.

On the Red Line, the sacred site of Mary Geoise is ablaze.

At the top of Pangu City, the instigator stands in the sky.

The pristine white navy cloak fluttered in the wind.

"Do you want to be at odds with the world?"

When confronted with questions from the world's nobles, Roy simply grinned.

"Haven't I already been at odds with the world all along?"

He smiled.

Those who followed him emerged from behind him.

The figures leading the group silenced the entire scene.

Everyone recognized them.

They are all powerful figures who have suddenly risen to fame on the high seas in recent years.

Among them were assassins, revolutionaries, pirates, merchants, doctors...

Without exception, they were all extremely powerful ability users, and they all belonged to the same organization.

Legend has it that the organization has a mysterious leader who is now the most dangerous criminal in the sea.

Now, the facts speak for themselves.

"You, you are..."

A new generation of legends in the Navy.

The most dangerous criminal in the ocean.

They were the same person from the very beginning.

His name is...Loy Amos.

Traveling through the pirate world, he was swallowed by the King of the Sea at the beginning, and then awakened the god-level [Cube Fruit]!

Everything in the world can be decomposed and reassembled! Others work hard to develop fruits, I directly read the data and synthesize it with one click!

While the navy was still showing off their pacifism, my 100-meter Diamond Gundam had already been assembled.

Everyone thought I was adventuring on the Grand Line...

They don’t know that every time I arrive at an island, I copy the data of the entire island!

The Battle of Marineford breaks out, and the eyes of the world are focused on the execution platform...

I printed a "Sky Island" directly above the Navy Headquarters! ?

He traveled through the world of One Piece and awakened the divine skill of manifesting fantasy characters and items.

Kamen Rider Kuuga storms Enies Lobby alone!

Digimon Agumon encounters a young Princess Vivi!

Spirit Detective Yusuke Urameshi (replaced by Raizen) transforms into a demon and confronts Aokiji head-on.

The omniscient and omnipotent Quincy King has descended upon Skypiea!

Multiple sun gods appeared in this world

Nico Robin, who became a Quincy, and Usopp, who gained Nen abilities, had their fates rewritten.

When fantastical characters from all over the world descend upon the world of One Piece, what kind of storm will this sea face?

At the beginning, he became Luffy's brother, went to sea with Luffy, became the vice-captain of the Straw Hat Pirates, and after leaving Luffy, he became the admiral of the navy. Let's wait and see what kind of actions he will make in the headquarters of the navy. ... Kizaru: Oh my, this generation of supernovas is too scary. Hawkeye: My position as the world's greatest swordsman is no longer secure. Sengoku: Garp, look, your grandson is causing trouble again. Liu Luo: Let me see which pirate is causing trouble again.

"Is there something wrong with the story of an ordinary person like me being reborn as a character in One Piece, only to be born on a ship and shipwrecked, ending up on Elbaf Island?" "What?! I transmigrated too early!?" — (Multiple female leads, no system, single world, multiple transmigrations)
