In the world of cultivation where immortals and demons intertwine, Luo Wuchen (an outstanding disciple of Kunlun) and Li Xiyao (a genius girl from Penglai) met for the first time due to a trial, and they experienced life and death together and developed a secret love. They reunited at the Dao Da Ceremony, but they were entangled in love but were forced to alienate due to sect disputes, and they insisted on staying together because of their sincerity.
During the confrontation between immortals and demons, Xiyao was seriously injured and on the verge of death while protecting Wuchen, and her spiritual veins were destroyed; Wuchen violated the family rules for her and did not hesitate to harm himself, but it was still difficult to change his destiny. In desperation, Xiyao ventured into the Netherworld alone for a chance to survive, but found herself in a desperate situation.
In the end, on the bank of the River Styx, fate cannot be violated, Xiyao's soul disappears, and she protects Wuchen for the rest of her life with her destiny talisman. Since then, Kunlun has a crazy disciple who wanders around with his bones wrapped around his sword, guarding his lover who will never come back after the fairy road is destroyed, and fulfills the sadomasochistic fate of "love is hard to burn".
