Xiao Yuntian, an ordinary young man from Caojiabao, accidentally rescued Cao Xiaoxue, the daughter of the lord of Caojiabao who was being chased and fled. The two of them accidentally broke into the forbidden area, hoping to be discovered by the mythical beast in the forbidden area, and fell into the abyss. Mengyao, a saint from Miao territory, and Duan Yiyun, a disciple of Shushan, were entrusted by the head of Shushan to find the Five Spirit Pearls that had disappeared for many years. By chance, Xiao Yuntian and Cao Xiaoxue were rescued from falling into the abyss.
The four of them embarked on the road of the mortal world and became irreversible friends. Xiao Yuntian accidentally obtained the divine sword and got involved in family disputes and rivers and lakes battles in Caojiabao. During the dispute in Caojiabao, Cao Xiaoxue learned her true identity and secretly fell in love with Xiao Yuntian.
At the same time, the demon army began to move in an attempt to unify the six realms. The demon king broke into Shushan and wanted to snatch away the five spirit beads. In order to save Xiao Yuntian, Cao Xiaoxue blocked the demon king's attack, and her soul left her body and drifted into the ghost world. Cao Xiaoxue discovered in the ghost world that she and Xiao Yuntian had been destined for three generations, and their fate in this life was over. The three of them chased to the ghost world, found Cao Xiaoxue's soul, and learned about the conspiracy plan of the demon world army. With the help of her ghost mother, Cao Xiaoxue reversed her destiny and successfully returned to the human world, but she could only stay there for three months.
Back in Shushan, Mengyao told Duan Yiyun that she was a descendant of Nuwa and was destined to sacrifice for the world. Duan Yiyun heard this and decided to face it together with Mengyao and would not let her bear everything alone. The army of demons has invaded the human world. The four of them resolutely fought against the Demon Lord, but they had no choice but to find that the Demon Lord's magic power was really unfathomable.
