Beneath the shadow of the Kaiyuan Golden Age, Shen Shu, a young coroner burdened with the fate of a “star of ill fortune,” is forced to team up with Li Qi, a disgraced imperial grandson with a supernatural “photographic memory” who has been framed and imprisoned. Together, they investigate one strange and baffling case after another, gradually unraveling the mystery of the “Bai Ze Diagram,” a puzzle spanning three dynasties and entangled with imperial secrets, ancient mythical beasts, and eerie occult arts. Beneath Chang'an's resplendent facade, they expose the dark heart of power, human nature, and faith.
