In the World of One Piece: I'm Really Not an Undercover Agent

He transmigrates into the pirate world forty or fifty years in the past, digs up the Golden Lion's treasure from the start, and activates the Strongest Swordsman System.

It's an era when Roger is just starting out, Edward has yet to become Whitebeard, and Kaido and Big Mom are still just crew members.

Lu Jie says he doesn't mind becoming the young shadow haunting all these legends!

Golden Lion: "If Roger was the rival I fought all my life, then Lu Jie is the shadow that's haunted me all my life!"

Roger: "The title of Pirate King? I just never cared enough to claim it, that's all."
