The One Piece System Forces Me to Fight

Dongxin woke up and traveled to the world of One Piece. With his heart trembling with excitement, he asked if the system had it? Yes, but my system seems to be more violent. Other people's systems can be upgraded with krypton gold. Why can't my system be upgraded? If I want to upgrade, I can only fight! I'm a good young man, okay? I just want to come here to experience the wonderful life of salted fish, and see if I can pick up Nami and Robin. I didn't want to fight with that violent maniac! However, this world is too dangerous. If you want to be salty, you have to upgrade. If you have no choice, you will kill anyone who gets in the way.
