In ancient times, the demon god Jiuyou was a disaster for the people. Fortunately, Yi shot him dead in Yunmengze. However, the demon god died but his soul remained immortal. Later, the ancestral witch Zhu Jiuyin suppressed it in Yunmeng Canyon. The descendants of the witch clan guarded it for generations, and made a prophecy that only the goddess of the witch clan could kill the Jiuyou Yuanshen.
Twenty years ago, Qin Tianzong, a genius disciple of the Xuantian Sect, was bewitched by a demon girl. He fell in love with the demon girl and gave birth to a son named Qin Yunhai.
Nine years ago, Yunmeng Canyon was suddenly attacked. Someone broke the demon's seal and stole the Golden Silkworm Gu and Heartless Gu. The saint Liyue disappeared mysteriously, and the tribe wanted to extract her daughter Shen Xing and Shen Yuanshen to seal the demon. At the critical moment, Qin Yunhai traveled from the future, changed his name to Ayun, and used his immortal cultivation to save Xingchen and seal the demon.
Nine years later, Shen Xingyao came out of Yunmeng Canyon and searched for Ayun for thousands of miles, but found that the person he was looking for had completely forgotten what happened back then. After going through many hardships, the two of them discovered the truth about the eminent monk's demonization and the theft of the golden silkworm Gu. Later, when he met Ling Heng, he discovered that Qin Yunhai had already been poisoned by the heartless poison...
