Main plot (highlights):
The protagonist Ryan is a poor astrologer who accidentally activates the [All Souls Illustrated Book] that can collect and analyze ghosts. In order to survive and make money, he began to accept commissions and deal with various supernatural events. The main plot revolves around the protagonist's use of the illustrated book's abilities, starting with the lowest-level earthbound spirit, constantly solving difficult supernatural cases, quickly upgrading, and acquiring the ghost's exclusive skills (such as the "curse" of the vengeful spirit and the "illusion" of the succubus). In the process, he met the heroine, the church's relic refiner. From mutual disdain to joint cooperation, he gradually uncovered a huge conspiracy that attempted to subvert the kingdom and let the dead rule. The highlight of the plot is the fast and exciting cycle of "one case, one ghost, one skill". The protagonist uses the information gap and the endless ghost abilities to constantly slap the faces of the powerful and the church, and grows from a small person in the market to a legendary soul-suppressing master.
