I Am the Dragon King in One Piece

Traveling through the world of pirates, he became a slave to the Celestial Dragons at the age of six. Forced to eat an unknown devil fruit. Ten years later, with the dragon's claws and black-gold thunder and lightning, Karl broke through the holy land of Mariejoia. The sea trembled, and a legend stood on the blue sea. Dragon Man: Spare me, I'm not a god, I'm just a piece of shit! Kaido: Boy, come to my ship, I'm very optimistic about your phantom beast species. Karl: Not interested. I am a nine-headed dragon. Why are you fighting with me? The Celestial Dragons, the Navy, the World Government, destroy them! This novel and its characters are purely fictitious.
