Episode Summary
Police identify Liao Yunsheng as the prime suspect after finding forensic evidence linking him to the crimes. Qi Sizhe profiles the killer as someone suffering from a delusion that they are a spider. The police raid a factory and rescue Li Shuting, but the attacker escapes. The team realizes the killer's pattern has shifted. They track the suspect to a new apartment, only to find Liao Yunsheng bound in a cocoon, making him a victim rather than the perpetrator.
Spoiler Alert
The Evidence Piles Up
The forensics team came through with the goods. They matched the shoe treads and mud found in Liao Yunsheng's home to the Bat Cave. Liao also has a history with bovine tuberculosis experiments. This puts him directly at the crime scene. He is officially the prime suspect.
The physical evidence connects everyone. They found Xie Yaoqi's hair at the pork shop. Li Shuting's phone rang inside Liao's apartment. Han Feng has a working theory now. He thinks Liao killed Ye Yingying first. Then he kidnapped Xie Yaoqi and Li Shuting. The lab results back this up. The syringe residue in Liao’s home is funnel-web spider toxin. It is the exact same poison found in Ye Yingying’s body.
Inside the Mind of a Spider
Han Feng splits the team to chase leads. Qi Sizhe goes to see his friend Chen Chuchuan. Chen is a psychologist. He explains a specific condition to Qi. It is called clinical lycanthropy or zoanthropy. The patient believes they are an animal or an insect. Trauma or drug abuse usually triggers it.
Qi digs through the books in Liao’s greenhouse. He reads up on funnel-web spiders. He notices a calendar marked with a thirteen-day span. That is the time between mating and egg-laying. The killer isn't just wrapping bodies. He is creating egg sacks.
The Factory Raid
The team learns more about spider behavior. If you destroy a spider's habitat, it moves. Qi shares a grim fact with Zhu Qingyue. Female spiders often kill the males after mating. The victim is an egg, not prey.
Han Feng tracks a distress call. It likely came from Li Shuting. Li Xiaoxi spots a suspicious figure on the cameras near an abandoned factory. Han Feng drives straight there.
The team sweeps the factory. A man in black attacks Qi Sizhe. Han Feng rushes to help. The attacker escapes. Han chases him but loses the trail. Instead, he finds Li Shuting. Her head is wrapped tight in plastic wrap. She is suffocating.
A Flaw in the Pattern
Li Shuting survives. She talks to the police. She reveals Xie Yaoqi was dating Liao Yunsheng. Li went to Liao’s house to find her friend. Someone drugged her and moved her to the factory. She didn't see the attacker's face. She only knows he acted like a spider.
Qi Sizhe senses a problem. The killer changed his logic. He grabbed Li Shuting differently. It feels wrong. Han Feng agrees. They go back to the factory. There are no webs there. The first two crime scenes had intricate webs. This breaks the pattern. If the killer's logic shifted, Xie Yaoqi is in immediate danger.
Chen Chuchuan calls Qi with a lead. A patient at his clinic claimed to be a spider. He left before the receptionist could get his name. The security footage is too blurry to identify him.
The Hunter Becomes the Prey
Police track the suspect’s route on CCTV. They narrow it down to a residential area near the overpass. A utility bill from the greenhouse gives them a specific address.
Han Feng and the team raid the apartment. It is empty. Books on cow pathology sit on the table. They check the back room. They find a human cocoon. They cut it open. It is Liao Yunsheng.
