Thousands of years ago, after Sun Xiaotian (Xie Miao) created a miracle of saving the world, he was impersonated by a nine-way monkey. He suffered severe blows and lost his supernatural power. Relying on his mortal body, with the help of Di Ting (Yi Zhengfu), Dongfang Mo (Lin Yu), the young master of Wanzong Villa, and Sang Huai (Jin Yana), the Saint Girl of the Nine Heavens, he saved the people. In the process, he accidentally met and fell in love with Yu Bingxin (Nan Sheng), the princess of the Wan Yao Cave, the supreme ruler of the demon world... After going through thousands of dangers, he collected the three magical weapons, defeated the four demon kings, fought against the nine-way monkey, passed five levels and killed six generals, and finally gained great love and his "true self".
