Chen Wen, an urban planner, thought he would live an ordinary life. But after his great-grandfather sends him a message in a dream from the underworld, he is forced into a storm sweeping across both realms. His great-grandfather, a highly respected yin-yang master, is in grave danger, his soul trapped in a sinister, mysterious formation deep in the Underworld.
A sealed family journal gradually reveals that the Underworld is undergoing a transfer of power brought on by old grievances. A mysterious faction that opposes the old rules is stirring up a massive upheaval, intent on reshaping the realm of the dead and placing the delicate balance between the human world and the underworld in peril.

From warnings and guidance offered by his relatives in southern Anhui to exploring the secluded valleys of Mount Qingcheng in Shu, every step brings the unknown and danger, and every clue points to a deeper mystery.

A contest between mortals and spirits, tradition and change, is quietly unfolding...
