In the fourth year of the Republic of China, Yuan Shikai intended to become emperor, and the political situation was turbulent. In the autumn of that year, Wusong Town was hit by a fire, and tens of thousands of victims were killed. The already mixed Wusong Town seemed even more turbulent. Due to the collection of local donations, Wusong Town rebuilt the residents, but an accident occurred when a house was erected. During the period, a male corpse was exposed, and its appearance was strange, which caused rumors in the town. The townspeople were panicked and raised funds to ask monks and Taoists to perform rituals to exorcise evil spirits and transcend. During this period, there were also quacks and sorcerers, which made the town a mess. Lu Yue, the head of the town defense corps, was born in the army and did not believe in ghosts. Seeing this situation, he was furious. On the one hand, he ordered the monks and sorcerers to disperse, and on the other hand, he sent people to find the town's charity cemetery coroners Wu Yungen and Liu Guiyuan, and ordered them to perform an autopsy to find out the cause of death and set the record straight. Shi Lezhi, a poor young squire in the town, had traveled a lot when he was young. When he heard about the case, he rushed to check it out. Seeing Lu Xiangyi present, he wanted to show his ability, so he just kept criticizing and commenting, and was quite disdainful of Wu Yungen and Liu Guiyuan. Wu Yungen didn't care about it, and examined the green buds on the body of the dead man. He looked quite shocked, and then made excuses as if there was something hidden, and didn't say much during the period.
