In order to investigate the truth behind the death of the madman, Wang Fudo and others conducted an autopsy and found numerous wounds on his body. They found clues through his clothes and suspected that the murderer was a premeditated murder.

Yan Qi, Guo Dalu, Lin Taiping and Wang Fudo returned to Fugui Villa to analyze the case. Yan Qi wondered whether the recent serial murders in Ping An Town might be a murderer, but Wang Fudo believed that because of the cause of death of the three peopleIt's different from the modus operandi. It was completely done by three people. It doesn't look like it was done by one person. There are only two possibilities. One is the murderer who deliberately hides his method. The other is that there are really two people.

While the four people were discussing the case, Chao San suddenly came to Fugui Villa and told the four people that Xiao Yulang had been killed at home again.Moreover, because there have been a series of killings in the recent period, Chao San has not caught the murderer and has no clues at all. People in Ping'an Town think that Chao San has no ability and cannot maintain the peace of the party, which makes Chao San very angry.Now that we have come to Xiao Yulang's home to investigate the cause of Xiao Yulang's death, the cause of Xiao Yulang's death is also very strange. It doesn't look like he actually died from a knife attack, because he died from a knife attack and should have suffered from excessive blood loss.After everyone searched and investigated, Yan Qi saw footprints outside. According to the footprints, Yan Qi found a pair of embroidered shoes in the grass, which happened to be the same as the footprints.

Wang Fudo and Guo Dalu were planning to investigate the surrounding neighbors to see if they could find any useful clues. However, the neighbor's daughter-in-law was very happy after hearing that Xiao Yulang was dead, and even cursed Guo Dalu for thinking that he was a human being.They are all dead and shouldn't do this, but the neighbor's wife claims that Xiao Yulang is a pervert and they can be cleaner if they die.

Mao Xixi said that she was not afraid of the perverted murderer. Guo Dalu was a little worried, but Mao Xixi repeatedly insisted that if this man was not caught, the whole town would be panicked. Even if something happened to him, he was not afraid of a weak woman.It will encourage the whole town.Guo Dalu decided to stay at Mao Xixi's door to protect him. Sure enough, a masked man came at night. Guo Dalu fought with the masked man and beat him away. The other party left a jade seal. Guo Dalu took the seal.They were given to Yan Qilin, Lin Taiping and Wang Fudang to watch and look for clues together.

Yan Qi claimed that he had clues, and also called Chao San, and asked Guo Dalu to find Mao Xixi as well, preparing to announce his results in front of everyone. When everyone arrived, Yan Qi said based on the clues he had investigated that Mao Xixi wasThe murderer, and Yan Qi also told Mao Xixi’s motive for the murder. Everyone here was related to Mao Xixi, and the motive for the murder was also very sufficient. After hearing this, Mao Xixi cried aggrievedly, while Guo Dalu kept defending on the side..

Yan Qi Guo Dalu had a conflict over Mao Xixi and almost started a fight. At this time, Wang Fudo made a new discovery.Wang Fudang saw two stilts and demonstrated how Xiao Yulang spied on the neighbor's woman. It turned out that the pair of embroidered shoes in the corner were used by Xiao Yulang to step on the stilts. They could stabilize the stilts and had nothing to do with the case.Yan Qi also deduced that Mao Xixi was the murderer based on the embroidered shoes. Now that the embroidered shoes were not inside the buttons, the guess was naturally wrong. Mao Xixi also kept crying aggrievedly and persuaded Guo Dalu not to quarrel with Yan Qi anymore. Yan QiAlso because of the case, Yan Qi was very unconvinced but still apologized to Mao Xixi.Yan Qi used a magnet to suck out the mosquito bites from the deceased, proving that the real cause of death of these people was the whisker needles, and that the knife was just a way to cover up the murder.Guo Dalu suddenly remembered that the masked man he met was very similar to Mr. Huang.
