Douluo: Integrate Kaido's Spirit of Beasts at the Beginning

Zhao Kai's soul traveled to Douluo Continent and lived in the same era as Tang San. Hiss~ But with your height of 185cm, strong muscles, and long black curly hair, are you really ten years old? And your Qinglong martial spirit and the mace next to it? Pirates fans, don't ask where your "much cuter" teacher is. He was punched by Tou Fai and landed on the ghost island, then traveled through Douluo and became a teenager, and was passed through my soul again! But since Kaido is the strongest man on land, sea, and air, why can't I? I, Zhao Kai, want to become the strongest Douluo in the sea, land and air!
