Zhang Xiaoquan, who has a supernatural physique, was involved in a series of absurd, terrifying and hilarious supernatural events due to the frequent occurrence of strange things in the city. He formed an alternative detective team with his partner Li Xue and Ghost King Ergou to investigate various ghost cases. As the case escalates, the hidden "spiritual ecology" of the city is revealed, and the final showdown with the evil spirit Xu Ling'er begins. The three volumes cover the detection of strange cases, the growth of friendship, the revelation of the spiritual world, and humorous battles. Each volume is independent but interlocking, with a compact main line and ups and downs of the plot. In the end, Zhang Xiaoquan used humor and wisdom to bridge the gap between humans and ghosts and protect urban peace.
