Traveling through the world of pirates, becoming Luffy, and possessing cheats in teaching space, it is natural to make changes.

When Chambord landed on the island, the pacifist, the general Huang Yuan, appeared, and all the supernovas fell into despair except the hat group.

Seeing Zoro sweeping the world with a single sword, Sanji the Demon Kazekaku, and Luffy blasting away the oracle with his four-speed karma fist gun, the supernovas were stunned.

“Is this a supernova? I’m afraid it’s not the imperial group!”

During the war on the top, the hat regiment descended with the momentum like a royal regiment.

On Ghost Island, Kaido and Big Mom satirized: “Hey, boy, what are you going to become? Say it again in front of us!”

Luffy opened five gears furiously, his fist was as huge as a ghost island! A five-speed Yehuo fist gun! Party Kaido and Big Mom!

Luffy landed, the black stand-up collar cloak fluttered, put on the helmet, and whispered domineeringly:

“I’m Monkey d Luffy, the man who wants to surpass you and become the One Piece!”
