Su Yan, an undertaker who can hear the obsessions of the dead and fulfill their final wishes, has cracked one rules-based horror after another. While investigating the cause of his master’s death, he uncovers the truth about his own origins as “No. 7” in the Register. He confronts and topples the system of “Rulekeepers,” who feed on people’s obsessions, only to discover that every wish he has investigated points to one name that is still alive: his biological father, Su Boyuan.
