The heroine Song Ci, a modern forensic doctor, accidentally transformed into an unlucky couple whose engagement was broken off because she "examined a man's body." She believes that "the corpse is the best witness", uses modern science to defeat feudal superstition, let the corpse speak, and makes every dead person become a witness against the murderer. The behavior was considered deviant by ancient people, but it was also ridiculously accurate.
