Well versed in criminal law and skilled at distinguishing truth from falsehood, he sees through the treachery of human nature. He has no wish to be drawn into courtly conflicts again, but a strange case on a rainy night forces him back into the heart of the mystery.
The female lead, Zhang Lingwei, knows folk customs and strange tales. Careful and resolute, she dares to enter abandoned shrines and ancient post stations, and to investigate whether rumors are true. She believes in neither gods nor ghosts, only in human nature.
The two meet through a case. Guided by a single night lantern, they join forces to explore narrow alleys, deserted houses, old post stations, and forgotten shrines.

As their lantern light flickers, they must unravel baffling murders and face the forces laying a web of traps in the shadows.
