As the last descendant of the unique skill of Faqiu, Su Li is forced to partner with Lu Jinxing, an archeology professor who hates all tomb robbing, to explore the dangerous royal tombs in order to break the family curse. She is proficient in agency feng shui and walks in gray areas; he adheres to the scientific bottom line and is determined to bring her to justice.

This is a fierce collision between Jianghu occultism and orthodox archaeology, and it is also a fateful journey of seeing each other and two-way redemption in a decadent legend.
