The funeral industry has an old rule: once the deceased is placed in the coffin, the living must stay away. Shen Mo has worked as an embalmer for three years. He thought it was just a superstition of the trade, until one night on duty, a corpse sat up by itself. The soul-guiding knife, ancient bronze coins, and half a handwritten notebook left behind by his master dragged him into a world invisible to the living. High Martial powerhouses hide among ordinary people, seals over the Yin Eye are quietly weakening, and practitioners of traditional folk occupations have served as guardians of the night, suppressing the forces of Yin and Yang, for generations. When embalming rituals become sealing arrays and paper effigies are used to lure enemies, Shen Mo finally understands: the morgue at the funeral home is the most dangerous place in the entire northern part of the city.
