On a night swallowed by flames, Xuan Jin died of the betrayal of his relatives, but his soul did not return to the underworld, but wandered in the gap of the netherworld for seventy-seven and forty-nine days. The gentle young man in the past is now a necromancer, reshaping himself in the shadows and ashes. Using the blue soul lamp as his eyes, he can peer into the abyss of people's hearts and summon the dead to dance with shadows. Revenge is not his only desire, he also wants to uncover the mystery of why the wronged souls in the world cannot rest in peace. Xuan Jin's enemies are not just bloodline, but also the "Black Tower" that controls the cycle of life and death - a taboo place that mortals cannot look directly into. With every step he takes, Xuan Jin is competing with his own resentment, the ghost of his beloved, and the faceless man who controls his destiny. His revenge plan is a ritual dancing on the boundary between life and death, and a silent inquiry into the truth about the world of the dead. When the last soul lamp goes out, who is the cursed living person, and who can get real salvation?
