He's in the Navy and Has a Bounty of Tens of Billions on His Head. He's Really Not a Scumbag.

Linn travels through the world of pirates and gets a sign-in system. As long as he keeps signing in, he can continue to become stronger. So he signed in all over the world and helped and guided some people... Gradually, the style of the entire pirate world is a little different: Nami: "For Brother Linn, I can become a naval admiral or I can betray the navy!" Robin: "I am the son of the devil! From now on, let the world feel pain!" Uta: "Brother Linn! I want to create a world where there are only the two of us!" Hancock: "The king of Nine Snakes Island is none other than you, Linn!" Yamato: "Defeat my father, Kaido, just to meet brother Lin again!" Warring States: "That's enough! You come to tear down Marine Fando every few days for a scumbag. Don't bully me too much, you bastard! Damn it, Linn!" Lin En: "It's unfair. They all volunteered. I'm really not a scumbag!" This novel and its characters are purely fictitious.
