A Peking University doctoral student heads into the mountains in search of her father, only to uncover a Song Dynasty underground tomb hiding a thousand-year-old code!
A false tomb concealing a real one, secret words hidden in a bronze mirror, the Butterfly Army's tear-stained diaries, lost Song Dynasty originals, and the tragic remains of a tomb guardian: every discovery overturns what she thought she knew.
The villain appears, the killer is caught, and the truth about her father's death comes to light. He was both a criminal and a protector; both an undercover agent and a man seeking redemption. She is both a daughter and a guardian of civilization.
Of the 3,742 names, one is missing. Shen Yingyue carves the 3,743rd bronze mirror with her own hands, to honor the boy who guarded the tomb for fifty years.
As they refill the underground tomb, the wind passes through the bronze mirrors, carrying the sound of names being called from a thousand years ago. Three years later, a butterfly lands at a new excavation site, where a seed from seven hundred years ago lies buried in the soil.
