Bai Jiuci is an immortal in the immortal world. He committed a crime and was demoted to the mortal world. His memory was erased and he became the direct disciple of Immortal Zhen He on Qiyuan Mountain. The younger brother of Immortal Zhen He, Master Zhu She, was Gu Bei's master.
Bai Jiuci and Gu Bei got engaged out of anger and decided to get engaged three weeks later. However, after solving various problems in Pujia Village, he lost his memory when he came back. He was captured by the fox demon and controlled by the fox demon. Gu Bei found him. Under the control of the fox demon, Bai Jiuci returned to Qiyuan Mountain and killed his relatives with his own hands.
Gu Bei found Fairy Jiuqing at Xuanyue Peak, and with Jiuqing's help, he recovered all of Bai Jiuci's memories. Bai Jiuci returned to the fairy world after his ordeal.
Eighteen years later, Gu Bei ascended, and the two met at a banquet in the fairy world.
