In the World of One Piece: I Level Up Alone

My name is Su Chang, and I transmigrated into the world of One Piece. The story hasn't begun yet, but this is already a magnificent era.

Fortunately, I awakened a God-Rank Instance System. As long as I clear an instance, I can receive all kinds of rewards.

"Ding! Congratulations, Host, for clearing the instance with an SSS+ rating. You have received Rem, who is 100% loyal to you."

The moment an instance dropped a character for him, Su Chang knew there was more to this than met the eye.

This novel and its characters are entirely fictional. Any resemblance is purely coincidental. Do not imitate.
