Three days ago, the Shengcheng Branch accepted a case. The victim was an old man who often scavenged around the vegetable market.According to eyewitnesses, the old man was in an unusually excited state before losing consciousness. After a hospital examination, it was confirmed that he contained methamphetamine in his body.Zheng Bei and Gu Yiran happened to be on a business trip in Shengcheng. They personally went to the old man's residence to conduct a search. Although the house was filled with towels, cans and other sundries picked up by the old man, they could not find any clues directly related to drugs.Not a drug addict.

At the same time, Lawyer Liu went to the detention center to visit Brother Er Jin. After a brief conversation, he was about to leave, but Brother Er Jin eagerly asked about the situation of his daughter Jin Fei.Lawyer Liu's subtle attitude and a daily photo he handed over made Brother Erjin suspicious, suspecting that he was here under Jiang Yingzi's instigation.

Because he was extremely worried about his daughter's safety, Brother Er Jin speculated that something might happen to Jin Fei, so he proactively asked Zheng Bei for help, hoping to confirm Jin Fei's safety.It turned out that during this period, Jin Fei frequently went out with her friends and appeared depressed. Zhang Xueyao was responsible for monitoring her and urgently notified Zheng Bei because she suspected that she was taking drugs.

That night, Jiang Xiaohai followed Jin Fei to the alley and witnessed her buying drugs. He immediately took action to take her back to her residence and tried to control her drug addiction through restraint.On the other side, Zheng Bei launched an investigation at the request of Er Jin Ge, obtained the report record from the police on duty, and learned that Jin Fei had been raped by Lin Jiang.This news made Brother Er Jin angry and blaming himself. Zheng Bei and Gu Yiran took the opportunity to guide him to confess everything and revealed the truth about Jin Fei being injected with a large amount of drugs.Driven by his father's love, in order to reduce his sentence and protect his daughter as soon as possible, Brother Erjin finally decided to tell the whole story.

According to Er Jin Ge's confession, before his arrest, he learned about a new drug transport route from Xiao Ma Ge, but the specific details were unknown. He only knew that Qin Yi carried a bag of clothes.Gu Yiran quickly conducted a chemical test on the clothes, and Zheng Bei accompanied him throughout the entire process until late at night to confirm that there were drugs hidden in the clothes.

After in-depth investigation, the police revealed “Snow Angel”'s transportation method: using towels soaked in methamphetamine as a cover, evading inspection through long-distance freight, and then distributing the poisoned towels to various places.Through order comparison, Zheng Bei discovered that before Qin Yi was arrested, the purchase of towels at the Wanhuang Hotel surged and matched the towels found by homeless people.

After further tracking, the police found clues about discarded poisoned towels at a garbage station frequented by homeless people, and locked in a suspect named Xiao Dengtou.It turned out that after extracting methamphetamine, the little lamp head did not destroy the towel as required, but directly discarded it, causing the homeless man to misuse it and die.

Later, Zheng Bei and Zhao Xiaoguang followed the truck transporting poisoned towels to the Wanhuang Hotel, and found that Li Wenlong's car was also following it.They teamed up with the Shengcheng task force to sneak into the hotel and search the linen warehouse, but unexpectedly found that there was nothing abnormal about the towels in the hotel.

Director Guan of the Shengcheng Police Department decided to investigate the two cases simultaneously and appointed Zheng Bei to take command. The task force fully cooperated.In the Shengcheng task force, Zheng Bei and Zhao Xiaoguang were surprised to find that the members here had striking similarities with their team: Pan Er, a trace expert, had a similar body shape, Zhou Xi resembled a replica of Zhao Xiaoguang, and there was also a female Sanda champion named Sister Yuan, as well as Team Wang who looks exactly like Zheng Bei, and even Wu Gang, a drug testing expert from Kundu.

On the other side, Jin Fei realized Jiang Xiaohai's affection for her. In order to obtain “Xue Angel” information, she tried to exchange her body for it, but was rejected by Jiang Xiaohai.Just when Jiang Xiaohai was about to restrain Jin Fei again, there was a sudden knock on the door.
