I! Zu'an Native, Insult People to Get Stronger!

A weak transmigrator awakens the Emotion Value System in the One Piece world—every insult makes him stronger. Watch as his toxic words pit Kaido against Akainu, Doflamingo against Blackbeard, and even summon two Whitebeards to tear Marineford apart. Born without monstrous strength, Li Fan turns verbal warfare into his ultimate weapon. When his childhood sweetheart faces danger, rage unlocks his power: manipulate emotions, transfer anger, and orchestrate legendary battles while he claims his place atop Onigashima.
