Three Years of Sign-In at Impel Down, and I Orchestrated the Paramount War

He transmigrates into the world of One Piece.

From the start, he's given hell difficulty and locked up in the pirates' nightmare, Impel Down.

Fortunately, there's always a way out. He obtains a sign-in summoning System.

Luochuan quietly signs in at Impel Down for three years.

Then, on the day of the Summit War, Luochuan leads the summoned characters and takes charge of the battle!

Magellan: "Here's a joke. I'm a Paramecia-type Venom-Venom Fruit user, the 'Poison Man,' and a guy named Jia Xu poisoned me. I'm about to be poisoned to death!"

Bullet: "Aside from Roger, the only person I admire is that guy named Li Yuanba!"

Sengoku: "I'll catch you, Zhao Yun! You fought your way through the Summit War seven times over. Do you think I've got no pride?"

Luochuan waves a hand. "The summoned characters are so strong I don't even have to fight myself!"
