The story is set in modern society, where there are many supernatural phenomena hidden under the surface calm. Qianji Pavilion is a mysterious organization that has been passed down for thousands of years. It specializes in handling supernatural events that ordinary people cannot understand and guarding the balance of yin and yang. This organization masters the "Tian Ji Lu", which records countless ancient secrets and taboo legends. In contrast, the Blood Shadow Alliance, in pursuit of eternal life and powerful power, sacrifices innocent lives and frequently creates supernatural incidents in an attempt to break the yin and yang order. Against this background, a series of strange events occurred one after another, involving the protagonists in this undercurrent of dispute.
