Tonight, the Demon King Will Melt the Demon-Binding Chains for Me

Lin Wan, a hospice volunteer, encounters Shen Cangming, a silver-eyed man with the power to heal himself, at the hospital. By chance, she awakens the dormant Demon-Locking Chain mark inside her. It turns out she is the bloodline heir of the Celestial Master Qing Li, and the vessel of the chain that sealed Shen Cangming for a thousand years.

As the mark awakens, Lin Wan becomes a target coveted by evil spirits and malevolent entities. Shen Cangming proposes a pact: he will protect her life, and she will help him melt the chain. Together, they face man-eating evil spirits, eerie corpse puppets, and manipulated bridal ghosts, gradually uncovering the dark truth behind the Tianshu Bureau's human experiments.

Fragments of a thousand years of memories keep surfacing. The secret behind Qing Li's sealing of Shen Cangming, the truth about her mother's death, and the marriage bond ordained by Heaven all slowly come to light. From terror at the hospital to hunts in the demon market, from a blood stele in a dry well to the secrets of Huaiyin Village, their bond across a thousand years deepens as they face pursuit and uncover the truth.

When all the Demon-Locking Chain fragments have been gathered, the Tianshu Bureau's ultimate conspiracy comes to light. Can Lin Wan and Shen Cangming break free of their fate, melt the chain, and end this thousand-year feud and hunt?
