The famous Daoist Yuan Tiangang, having gathered the spiritual arts of the Maiyi and Maoshan schools, has quietly introduced the 'Seven Kill Orders of Ghosts and Deities' in the present era... In a certain alley in Beijing, there have been recent incidents of women being violently assaulted and dismembered after work. After multiple investigations, Police Officer Niu concluded that this series of cases was not perpetrated by humans. Wang Xiaoer, the heir of Daoist arts, will help the police solve various supernatural cases in order to pursue a police flower. The story appears to be a fantastical detective work centering around a lowly character, but it profoundly reveals the nature of humanity through humorous satire. It is seen as a groundbreaking classic work that subverts the common perception of comics as superficial reading material. Quan Yingsheng has also been dubbed the pioneer of 'realistic comics', and the comic includes his exclusive hand-painted contemporary ink wash series, greatly enhancing the artistic quality of the work.
