A few long hairs were picked up at the pork shop and have been sent for inspection.Zhu Qingyue told Han Feng that nearby villagers said that an unregistered wild theater crew had filmed here, and the puppets were all props that were not taken away. Based on the photos sent by the crew, Qi Sizhe discovered that the crew used ordinary spider webs, but the murderer changed them into the unique funnel-shaped spider webs of the funnel spider in the drama. He suspected that the murderer was imitating the funnel spider to hunt and kill.Although the victim was injected with spider poison and strong hydrochloric acid, the real cause of death was that the murderer injected an air injection behind the victim's ear.

At the case analysis meeting, based on all known clues, the police speculated that the kidnapped girl and the doll were not the same person. The kidnapped girl should have been imprisoned in the cave first, then broke the rope and ran out to the pork shop to seek help. Later, she was discovered by the murderer, who killed the boss and abducted the girl.As for the deceased, her name is Ye Yingying, 25 years old, a public relations officer for a marketing company. She has been missing for almost a month. During this period, there were no blackmail calls and no money was lost.Qi Sizhe determined that the internal organs inside the doll were from cattle, and the murderer most likely had a medical background.Zhu Qingyue profiled the murderer as having psychological problems and a certain sense of ritual, and the puppet should be the murderer's practice.

Based on the traces of the body being tied up and the calendar found in the cave, Qi Sizhe speculated that if the murderer was really imitating spiders to kill, then his imprisonment logic and crime cycle should have a fixed pattern.There are less than three days left and time is very tight.Han Feng ordered to go down, Li Xiaoxi went to investigate nearby surveillance videos, Wan Guoxin went to visit witnesses, and Su Huaining went to investigate Ye Yingying's colleagues and family members.There were no clues in the surveillance. Su Huaining found out that Ye Yingying liked medical beauty. Qi Sizhe determined that the internal organs in the doll were the internal organs of a sick cow suspected of bovine tuberculosis.Wan Guoxin received news that someone had reported missing, and according to the description, he matched the victim in the case.

Han Feng and Su Huaining went to the police station, and the reporter provided the WeChat records of them and their daughter Xie Yaoqi.According to the investigation, only the Agricultural University was doing research on bovine tuberculosis, so Qi Sizhe and Zhu Qingyue went to the school.Professor Wang told them that they had indeed conducted an experiment a month and a half ago, but the samples had been treated harmlessly. Qi Sizhe took tissue slices to Professor Wang, and Zhu Qingyue asked him to provide a list of students who participated in the experiment.

The reporter said that Xie Yaoqi was afraid of spiders. Han Feng met Xie Yaoqi's colleague Li Shuting in the courtyard of the police station. Li Shuting said that Xie Yaoqi had been fired. She worked part-time in a medical aesthetics clinic and used all the money she earned to do medical aesthetics.Professor Wang's comparison results showed that the internal organs inside the doll came from their experiment. Li Xiaoxi gathered all the students who participated in the experiment to the police station, and everyone conducted inquiries one by one.

Han Feng and Su Huaining went to the black clinic that Xie Yaoqi mentioned. The clinic was a masseur but secretly did medical beauty.Han Feng took out a photo of Xie Yaoqi. The boss, Liao Dong, said that she worked part-time as a nurse here. Han Feng also took out a photo of Ye Yingying. Liao Dong said that she was allergic to drugs when she came for medical beauty treatment, so he called his nephew, who was studying veterinary medicine at the Agricultural University, to help.Zhu Qingyue checked that there was indeed a student named Liao, and Han Feng asked her to arrest him immediately.There is a funnel-shaped spider web in Liao Yunsheng's residence, with many spiders hanging there, but no funnel spiders.

There were many portraits at the scene, including those of Ye Yingying, Xie Yaoqi, and one of an unknown girl. Han Feng saw that it looked like Li Shuting, so he called Li Shuting, and Li Shuting's phone rang on the spider web.
