The heroine An Yu travels through time, and her soul travels into the body of Si Huanyu, the daughter of the Demon King. In the battle between the demon and god realms, the demon king Sinanzu sent Huanyu to fight. Unexpectedly, Huanyu was seriously injured by Bai Che, the god of the gods, with the Yunyang Sword. Si Huanyu took the Yunyang Sword and fell to the Yinyang Mountain at the junction of gods and demons. After the war, Bai Che retrieved the Yunyang Sword and found that Si Huanyu was still breathing, so he took it back to his Yichen Palace, preparing to correct Si Huanyu.
