Five hundred years ago, Chen Xun, the God of War, lost all his cultivation and fell into madness in order to protect Xuanyuan Sword and seal Xuansha. Five hundred years later, he went crazy and wandered to Xiaohe Town with his spiritual wooden sword. Because the wooden sword sensed the aura of Nuwa on Old Li Tou, he met his daughter Li Yuan - the reincarnation of Nuwa. In order to help Li Yuan recover his memory, the two went to Daotian Sect together. On the way, Chen Xun suffered a madness and got separated. Li Yuan was taken away by Daotian Sect. Chen Xun met Zhao Ting, an iron fan, and entered the Immortal Cultivation Sect together. Unexpectedly, Zhao Ting turned out to be the reincarnation of Xuansha and was possessed by a magic bead. After Li Yuan regained his memory, he needed to work with Chen Xun to help him recover. After the dual cultivation was completed, Chen Xun opened the gate of heaven with one sword in the battle between Daotian Sect and Demon Sect. In order to break the five-hundred-year curse of reincarnation, all the immortals dispersed and returned to equality. In the end, Chen Xun and Li Yuan returned to Xiaohe Town and stayed together for the rest of their lives.
