After six years working as a corpse-burier, Lu Chen wants nothing but to live cautiously. Then, on a rainy night, the woman he has been ordered to bury opens her eyes inside the coffin, even though she died three hundred and three years ago. A book called Records of Buried Immortals and a burial seal of unknown origin draw him into the secrets hidden in the past of the Qingxuan Sect. The dead may not be at rest, and the living may not be trustworthy. From a tomb without a marker to the ninth coffin, Lu Chen must discover just who he has buried.
