Since the founding of the world by Pangu, the world has been divided into three realms: heaven, earth, and man. Each realm has its own realm and is divided into three realms of heaven, earth, and man. The master of heaven is Haotian, the master of earth is Houtu, and the human realm is divided into three persons: Ji Xuanyuan, Jiang Chiyou, and Jiang Yugong. The three realms represent the most basic rules for the operation of heaven and earth. After Pangu's death, the Yuan Shen transformed into the Three Pure Ones, but a thought unexpectedly merged into the chaotic atmosphere outside the sky. He felt that the Great Dao was unfair, and transformed into the evil gods (greed, anger, ignorance, hate, resentment, jealousy, pride). Because he was transformed by Pangu, no one in the world could destroy him. Only the combination of the three can subdue him. Because Jiang Chiyou was in Huangdi and others in his previous life. He failed to compete for the position of co-master. When he was treating himself, he was accidentally caught by a trace of the evil god, which caused the three-way fusion to fail. Chiyou took the initiative to break up the army, and asked the Yellow Emperor to scatter his body around for purification, and his soul entered the cycle of reincarnation. After thousands of years, the gods worked together to send him back, but he was disrupted by the evil god and accidentally sent him to the starting point of everything.
