One Piece: This Era Is Called Red Nose

[One Piece fanfiction] + [The mighty Buggy] + [Plot-focused] + [System-driven]

(This is a slow-burn story. If you want to save Ace and Whitebeard, start from the beginning. If you don't like the pirate side of the story, start at Chapter 14. The turning point is Chapter 18, where the novel's central theme takes shape.)

Zhang Wenjun transmigrates to the One Piece world and becomes the mighty Buggy. Using the System, he appears at the Paramount War from the start, and his actions leave everyone stunned.

He gathers his underlings and establishes the New World Company. As the world's fourth major power, he overthrows the Celestial Dragons and builds a world centered on socialism.

Neither pirates nor the Marines stand for true justice. The New World Company does!
