Episode 5 recap: Huang Bing De confessed to the truth of killing Zheng Ying.

Huang Bing De confessed to the truth of killing Zheng Ying.Captain Li and Zheng Dong Yu have been investigating the case of Huang Bing De. They found a noodle shop where Huang Bing De often dined. His life was very regular, and every morning he would go to the shop to order a bottle of white wine and a bowl of noodles.

The shop owner felt that this person seemed cold. Based on the description from the shop owner and considering the local temperature and climate, Zheng Dong Yu inferred that Huang Bing De was likely from a mountainous area. Recalling the description of the shop owner, Zheng Dong Yu noticed that Huang Bing De had a foul smell on him, even the money he gave had an odor. Zheng Dong Yu believed that he was likely a worker in a cold storage facility. They went to the cold storage and learned from the manager that Huang Bing De, using the alias Shi Erjin, worked there. Captain Li and the team only knew the alias, but there was no record of this person in the household registration data, leading them to conclude that Shi Erjin used a fake identity.

After Gao Yang was released, based on the clues provided by Captain Li, he went to Shi Erjin's house. Gao Yang discovered the words "Jiangdong Province Shooting Team" on the curtains in his house. Following the clues provided by Gao Yang, Captain Li indeed found relevant information about Huang Bing De in the provincial shooting team.

However, Huang Bing De remained tight-lipped. Even when confronted with the relevant information, he only answered with three words: "I don't know." Later, Zheng Dong Yu found information about Huang Bing De's wife, Xu Mei. When Xu Mei was eight months pregnant, she had a car accident while Huang Bing De was driving her to the hospital. In order to save his wife and unborn child, he accepted Liu Qing's money for taking a life.

Captain Li publicized this information, and it finally broke Huang Bing De's silence. He admitted that he was forced to do it. Liu Qing had ordered him to kill Zheng Ying, and he followed Liu Qing's instructions. Captain Li arranged for the team members to go to Sihe County the next day but specifically instructed them not to let Zheng Dong Yu go, claiming it was his own order.

The next day, Captain Li and the others took Huang Bing De to the location where he confessed to burying the body. They indeed dug up a body that had been burned multiple times. They also found the firearms used in the crime at Huang Bing De's house. After thorough examination, it was determined that the firearm matched the one used to kill Qin Yong. However, the forensic examiner could not find any evidence from the remains that could prove Zheng Ying's identity. The body had been burned multiple times, making it impossible to extract any valuable evidence. They could only extract some components from a portion of the teeth. Due to technological limitations, the forensic examiner suggested that Captain Li send the remains to the city forensic laboratory, as there might still be a glimmer of hope.

After Gao Yang was released, he went to find Lei Nai Wu. He pretended to remind Lei Nai Wu to think carefully about who he might have offended. Lei Nai Wu was very cautious and looked at Gao Yang, asking how he knew where he was and how he could save him.

Gao Yang quickly responded, saying that Chen Guangfa had contacted him out of concern for Lei Nai Wu's safety, which was why he had come. Lei Nai Wu stared at Gao Yang for a while without saying anything. Later, he said that his life belonged to Gao Yang and that he would repay the person who saved his life in the future.

In the evening, Gao Yang went to Zheng Ying's house, where Zheng Dong Yu was also present. He performed a ritual to honor Zheng Ying. Zheng Dong Yu told Gao Yang that she didn't believe the remains they dug up in Sihe County were her father's. Gao Yang comforted Zheng Dong Yu and hoped that she could accept this reality.
