He who steals a hook is executed; he who steals a country becomes a prince… he who steals heaven and earth becomes a saint!

From now on, please call me the Demon Lord of the Heavenly Thief!

Bad news: I traveled through time during the duel.

Bad news: This is the world of One Piece! You can't survive without fighting.

Good news: There is a cheat code. Bad news:

The original male body has been replaced with a mouthful of teeth!

"Kaido, you will be defeated today! Phantom turns one million horses - Super Conductive Wave Thunder Cannon Muzzle!!!"

"Hehe~ Hehe~"

"Ossi, Ossi? Wake up. Captain Kaido is calling you."

In the meeting hall of Onigashima, a red-haired girl who was talking in her sleep was gently awakened.

"Ah, ah? What's wrong?" The girl looked up blankly and saw Kaido's big face. "

Woooo ...

【No Depression】【Multiple Women】【Thunder Fruit】【Being the Boss in Two Worlds】【Black Technology】

Rocky, a "three-nothing youth" with no car, no house, and no girlfriend, unexpectedly awakens the ability to travel to the world of "One Piece".

His identity in the world of "One Piece" is actually a Celestial Dragon who stands at the top of the world!

In reality, he is an unknown little man on the fringe; in the world of pirates, as soon as he opens his mouth, the admiral of the navy has to obey his orders respectfully!

I originally thought that Rocky could only enjoy glory in another world, but I didn’t expect that he could bring “wealth”, “ability” and “technology” back to the real world!

From then on, the two worlds developed on two different tracks and ran wild at the same time!

In the world of pirates, he intercepted the Thunder Fruit, commanded the navy, subdued the Empress, and trained his own armed forces with the help of modern society.

In the real world, he develops super robots, releases exoskeleton armor, controls capital, crushes the powerful, and relies on the black technology of the pirate world to build his own world empire!

And all this started on the day of the time travel, when Rocky took the spicy strips in his hand and exchanged them with the Celestial Dragons for Boa Hancock.

After traveling to the world of pirates and being bound to the most powerful bandit system, as long as he behaves like a bandit, he can get a certain degree of reward. Qi Bai had no choice but to be 'forced' to become a bandit, so... "Red Hair, your daughter Uta has been kidnapped by me! You don't want anything to happen to your daughter, do you?" "White Beard, Ace is in my hands now! What price do you think you can pay to redeem him!" "Garp, your grandson Luffy is in my hands! You don't want to send your son away when you are old, do you?" "Kaido, your daughter Yamato is in my hands! You don't want to have a grandson so soon, do you?" "Five Elder Stars, the Celestial Dragons have been kidnapped by me..." "..." On the holy land of Marijoa, Qi Bai, who had just dealt with Im, lit a cigarette for himself: "Don't worry, let me finish this last job, and then I'll go to the next world!"

Su Chen traveled to the pirate world with a magician's inheritance.

After learning most of the magic, he met Luffy who had just set sail and accepted the invitation from the future Pirate King.

What kind of collision will occur between the gorgeous and magical magic and those magical devil fruits?

Nami, come here, let me strengthen your wind-type celestial magic!

Usopp, do you know about the magic bow and various attribute ammunition?

Sanji, do you want some top-quality ingredients from around the world? And some invisibility magic?

Hey, Robin, everyone has their own meaning of existence. If you don't even have the courage to try, you don't deserve happiness at all!

After being strengthened by Su Chen, would Luffy and others still watch Ace being killed during the Battle of Marineford?

All regrets will be made up!

[Boat travel + multiple female leads + action + comedy + Momonosuke and the deserter king are destined to die]

After Etherius Thor Dragneel learned Dragon Slayer Magic, he unexpectedly ended up in Windmill Village in the East Blue, where he became sworn brothers with Luffy, Ace, and Sabo. However, he ultimately chose to set sail with Luffy and began his adventure to become the strongest person in the world.

Nami: I love Thor the most!

Robin: What a bad guy!

Hancock: This is the legendary wedding!

In the Great Age of Pirates, the strong reign supreme! I, Yeager, have been taught a harsh lesson by the world. Now, all I want is to encounter Blackbeard, possess him, become him, surpass him—and finally, make this damned world feel the pain!!!

[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.
