Based on the novel by Xu Zhonglin. A lively seahorse and a little Dragon are looking for powerful artifacts hidden from prying eyes by the Heavenly Prince. If the artifacts fall into the wrong hands, the whole land is in danger. The cunning God of Thunder and the powerful but narcissistic warrior Erlan set out in search of the skate and the little dragon. When Dragon finds the Magic Lotus, he wants to take it to his mysterious master. He has no idea that he is serving the Prince of Darkness. When the secret is revealed, Dragon is faced with a difficult choice: to continue helping the evil lord of darkness or, on the contrary, to protect his new friends.
