In One Piece, the System Insists I'm in a Joyful Sect?

Luo Yu accidentally transmigrates into the world of Pirate King, only to discover that he has awakened a misfiring, stubborn System that mistakes this place for the cultivation world. From then on, Luo Yu keeps getting dragged back and forth by the stubborn System, straying further and further down the wrong path. Innate Nuwa Hancock? A reward: the Heaven-Mending Art... Isn't this just Haki's Meteor Fall? Demon Clan Saintess, Princess Shirahoshi? The Sea God's Ocean-Filling Art... Isn't this just Haki for moving the sea? Thunder Clan Saintess, Nami the Sky Thief? This Thunder God Body-Refining Art means I have to get struck by lightning? Charlotte, with the bloodline of an ancient giant? An ancient god's cultivation art... Luo Yu gave a wry smile. “System, even if it kills me, I'm not going near that one!”
