Thirteen Years of Dust 尘封十三载 Episode 17

Lu Xingzhi went to the art department to ask the teacher, and learned that the artist of this painting was an amateur because the proportions of the human body were not accurate. Wei Zhengrong went to find Bai Xiaofu, he had a great time with Zhang Shanshan's mother and son, Zhang Sicheng came to pick up Zhang Shanshan with a blank expression on his face. Zhang Sicheng is Bai Xiaofu's ex-husband, so it's normal for him to have a bad mood towards Wei Zhengrong. On the way back to the bureau, Wei Zhengrong suddenly missed his son and called his son from the public phone. When Lu Xingzhi came home from get off work, Yang Man immediately pulled him into the house and took out a pair of Yingli shoes that were popular in Nandu a few years ago. Today when Yang Man was cleaning, he took it out and tried it on, but Ning Ning cried when she saw it, she stopped crying when she took it off, she cried when she put it on.

Lu Xingzhi and Yang Man looked at each other, speculating that Ningning saw the shoes worn by the murderer at that time. In 2010, Wu Jia took An Ning to a tall building to see the scenery, making her forget the nightmare of the past and look forward. Yang Man followed An Ning, saw her with Wu Jia, and sent Wu Jia a message, not to stop them from being together, but to remind them to be safe and send An Ning home on time. An Ning listened to Wu Jia's words and played the violin. Seeing this, Yang Man drove away with confidence. Lu Xingzhi said that the shape of Qu Zhenxiang’s logo is similar to that of Yingli shoes. Although it is far-fetched, once you start to suspect a person, anything that seems unlikely may be regarded as a clue.

Wei Zhengrong mentioned an important point. The very small amount of skin tissue remaining between Moran's nails back then could not be detected with the technology at that time, but if Bai Xiaofu had frozen the skin tissue, it should be possible to detect it with the current technology . The master and apprentice went to Nandu University. After Bai Xiaofu passed away in 1998, the laboratory was taken over by Mr. Xie. Until the laboratory was separated from the public security system in 2002, only Mr. Xie knew the whereabouts of the physical evidence. Teacher Xie is not at school now, and has gone to the UK as a visiting scholar. Lu Xingzhi got Teacher Xie's email. Returning to Southern Metropolis University, Wei Zhengrong inevitably thought of Bai Xiaofu, and his face was a little dignified. He asked Lu Xingzhi to go with him to see Bai Xiaofu.

When Bai Xiaofu passed away at the beginning, Wei Zhengrong was in great pain and would always think of her. After a few years, he would think of her only once in a few days. Until now, he could not remember the specific face of Bai Xiaofu. Half of the reason Wei Zhengrong left the criminal police team was because of Bai Xiaofu. In 1997, Lu Xingzhi told Wei Zhengrong about the Yingli shoes, and Wei Zhengrong took Lu Xingzhi to Hu Haixia to learn about the Yingli shoes. The two then went to the city library to ask Moran's colleagues about Moran. Lu Xingzhi proposed to find the names of the library cards on the detective novels to sort them out one by one. The workload was heavy, but Lu Xingzhi took the initiative to find them himself. Wei Zheng In the end, Rong also searched with him.

In 2010, Director Huo told Lu Xingzhi that the physical evidence of the Moran case was not lost, and he could go to the City Bureau to find Lao Yi, a technical investigator. Lu Xingzhi received a call from the United Kingdom. The other party's surname was Gu. Du Mei, who claimed that he didn't know any rich man, hoped that Lu Xingzhi would stop harassing him. Qi Shasha provided the master and apprentice with clues about the liar Li Demin, but later found out that Li Demin owed her money and did not pay her back before lying to the police. Lu Xingzhi didn't find any physical evidence, so Lao Yi asked him to wait. In 1997, the master and the apprentice took the library card to make copies. The workload was heavy, and Lu Xingzhi recorded the shoes worn by the people who came to borrow the library. Knowing that the murderer's name was among the library card holders, but not being able to identify who it was, this feeling made Lu Xingzhi very desperate.
