After arriving in the world of One Piece, Fang Mu is accidentally captured and thrown into a rabbit pen to serve as a prisoner.

He thinks he's the unluckiest transmigrator ever, but then he awakens a sign-in System. As long as he checks in, he can keep getting stronger.

"Congratulations, Host. Your sign-in reward is Observation Haki."

"Congratulations, Host. Your sign-in reward is Armament Haki!"

"Congratulations, Host. You are now invincible."

He plans to use the System to climb step by step to the top of this world. But then, one day, a woman appears before him.

"Young man, would you like to save yourself twenty years of hard work?"

And so, while loafing around and living off the Navy, Fang Mu sets out on a path of no return!
