One morning, Lu Xingzhi suddenly remembered an article his father once mentioned, and asked Yang Man to translate it in order to find ideas for solving the case.Later, Wei Zhengrong received a message. Lu Xingzhi guessed that the message came from a public phone outside the police station, so he and Wei Zhengrong rushed out together, but they met Zhang Sicheng, so they guessed that the message was from a public phone outside the police station.He came from Zhang Sicheng and did not pursue it any further.Lu Xingzhi mentioned that his father invited them to dinner and hoped that Wei Zhengrong must attend.

During the meal, Lu Xingzhi talked about serial murder cases in foreign countries and tried to look at the pencil murder case from a different perspective.However, Wei Zhengrong believed that these foreign cases were not applicable in China, and accused Lu Xingzhi of seeing these things as useless.Father Lu smiled awkwardly because he had suggested that his son watch these contents.But Lu Xingzhi continued to express his opinion. He believed that the Liu Meng case might not be the first time the murderer committed a crime.Although Wei Zhengrong did not object to his investigation, the premise was that his work could not be delayed.So Lu Xingzhi immediately stood up and returned to the police station to check the file.Both Wei Zhengrong and Lu's father had served in the military and were police officers, so they had many topics to talk about.Wei Zhengrong was filled with emotion and felt that he should have been like Lu's father and joined the army after getting married.

In 2010, Lu Xingzhi issued a military order to Bureau Huo, hoping to solve the case within a month. If he failed, he would resign.Bureau Huo scolded him, pointing out that if the case was not solved, the victims would not get justice and the police would be held accountable.These words made Lu Xingzhi strengthen his determination, and he also hoped that Huo Ju could encourage him.Later, they got information about a new deceased person.This woman named Xue Hong is an employee of Rourou Hair Salon on Jiangyin South Road.Since this hair salon had a criminal record, the deceased's information was found relatively quickly.The deceased had been severely beaten before his death, which was different from previous victims.In addition to the deceased's DNA, Lu Anning's DNA was also found on the strawberry doll.

During this period, Yang Man noticed that An Ning sprayed her own perfume, dressed up carefully, and left the house.Worried about An Ning's safety, she followed him.Lao Du returned to the police station and joined the investigation team. The manpower was increased and the investigation progressed faster.At the same time, Lao Zhu and Lao Du went to Xue Hong's home to inquire, while Lu Xingzhi and Wei Zhengrong went to Rourou Hairdressing Shop.This store was rented by a 19-year-old girl and Xue Hong, who planned to sell a Taobao store. After the news of Xue Hong's death, the girl kept crying.She provided a useful clue: Xue Hong had received many different people, including middle-aged and young people.Lu Xingzhi showed her a photo of Qu Zhenxiang, but she denied knowing him.

In view of the many homicides that have occurred in Nandu, Wei Zhengrong is very worried about this and hopes to catch the murderer as soon as possible to help the victims.Therefore, he took Lu Xingzhi to the scene of a murder on the south bank and discovered the hidden compartment of a cabinet.He handed Lu Xingzhi a clothes drying pole and found an oil painting of a human body in the grid.This painting is exactly the same as Liu Meng's posture when he died, so the two believed that this was a case committed by the same murderer.
