Remos traveled to the world of pirates and activated the destiny simulation system.

As long as you follow the concept of destiny, the degree of fit will continue to improve, and you will walk on it and become a destiny traveler.

"My first destiny is hunting? Very good. From today on, I'm a sea ranger... Hey, that title is quite fitting."

Remos blew on the muzzle of his gun, threw the bounty order on the pirate's body, and said with a smile.

"I got to this point without making any effort; it's all thanks to my talent and ability."

He was Cavendish, the sole heir to the Kingdom of Brugesia, but because he was too handsome, women in the kingdom were unwilling to marry him, so the king exiled him for the crime of being "too popular."

Even on the high seas, he remained just as popular.

By a twist of fate, he found the legendary Flame-Flame Fruit, which even dogs wouldn't eat, but he discovered that the fruit wasn't as bad as the rumors suggested.

Where does the mysterious alternate personality come from? What does the blue Sharingan really mean? What secrets does the Flame-Flame Fruit hold?

(Everything Cavendish does is based on reasonable reasoning from the original work, ensuring it's not offensive.)

Wayne, who transmigrated into the body of a pirate, awakened the Good Citizen System.

Living in the world of One Piece, he must strictly adhere to the labor laws of his previous life, arriving at work and leaving on time.

As long as he strictly follows the rules, he will reap a bountiful harvest every day.

Physical fitness, swordsmanship, martial arts, and domineering presence.

Everything you could want!

And so began his unique path of law-abiding piracy and robbery.

...

Nine o'clock in the morning, starting a beautiful day.

Burn! Kill! Loot! (Omitted)

At 5 p.m., a busy day came to an end.

His brothers, looking at the city they had finally managed to conquer, were unwilling to give up and wanted to break the rules.

But after being educated on the law by law-abiding citizen Wayne, they could only follow him back with their faces full of embarrassment.

Before leaving, Wayne shouted to the townspeople, "Wait! I'll come back to rob you again at nine o'clock tomorrow!"

...

As time went on, Wayne's strength began to become unfathomable.

Due to his eccentric behavior, the Navy paid close attention to him but did not take him seriously.

Until the Marineford War many years later.

Seeing Wayne slice the entire Marine Headquarters in two with a single stroke, the Marines finally realized what was happening.

This little pirate they didn't pay any attention to seems to be a tiny bit stronger than they thought...

Whitebeard: "This is it!"

Ace: "Uncle Vegeta, save me!"

Warring States Period: "This is it, we're doomed."

Just when everyone thought the outcome of this battle was sealed...

Wayne: "I won't bother you anymore, I'm leaving now. It's time for me to go home."

Whitebeard: ? ? ?

Ace: ? ?

"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)

Fisherman Jerry inexplicably traveled to the world of One Piece, and happened to be pulled onto the boat by Ace. After witnessing Ace's journey to find his father. He traveled around the world with his friends, all the way back to the Four Seas on the Grand Line, and then from the Four Seas to the Grand Line, hammering back and forth for three days and three nights, his hands and feet moved, he never blinked, and his eyes were not dry. "Why are your eyes not dry?" "Because I'm not like you who want to be dry all day long!"
