Sign-In at Marineford from the Start

Gu Chen transmigrates into the world of One Piece, becoming a lowly Marine at Marineford and awakening a sign-in System.

The Six Powers, three types of Haki, powerful Devil Fruits...

As long as Gu Chen keeps signing in every day, he can claim all kinds of rewards.

With the mindset of a mere passerby, and knowing nothing about One Piece's plot, Gu Chen decides to keep his head down at Marineford. Nowhere is safer than Marine Headquarters.

He never expected the Summit War to arrive.

He has never once made a move, but a single basic attack leaves Mihawk stunned and throws Blackbeard's plans into disarray.

Because of him, this world is completely thrown into chaos!
