The great master of the generation, Yan Wuxing, once accepted the young man Ling Wan as his only disciple on the top of the snow-capped mountains. He used his hair as a contract to form a bond between master and disciple who share the same path and fate. However, things are unpredictable. Yan Wuxing personally knocked Ling Wang off the Zhuxian Cliff. Since then, he has lost all his cultivation and his body has gradually decayed. For ten years, he has been trapped in the nightmare of chasing his disciples with his own hands, and he has been tortured by his inner demons day and night.
Ling Wan possesses pure demonic blood, survived after falling off the cliff, and eventually became the demon lord. When Yan Wuxing was critically ill, he reunited with Ling Wang, who had become a demon, in a dungeon dream. The old wound on Ling Wang's chest caused by Yan Wuxing had not healed for ten years and became an obsession engraved in his bones and blood.
The story is interspersed with memories of the past: the young man is arrogant, sincere and passionate, and has gone through severe tests such as losing his mind and bearing pain to become a master. Yan Wuxing's coldness and isolation hides a gentleness that is not easy to detect. Yanqing, on the other hand, is actually a puppet made by Yan Wuxing using fragments of heaven. He is ruthless and obedient, adding a sense of fate and the pull of the puppet to the story.
Now the master and disciple are facing each other, one is a dying immortal master, and the other is a paranoid demon lord. Ten years of grudges, blood fate, and unbroken love are intertwined. Ling Wang brings the comatose Yan Wuxing back to the dormitory. The past master-disciple relationship and the current love and hate are entangled in the darkness of the ghost world. An entanglement about obsession, redemption and fate begins.
Intention: obsession and redemption, love and punishment, fate and choice
