After Xu Wenguo fled, there has been no news. Du Xiangdong was implicated by Xu Wenguo and was isolated and censored for a while. The director asked Du Xiangdong to live in a single room in the guest house, and specially asked people to take care of him, and he was not allowed to go there.

After Liu Fenfang, Du Xiangdong's object, learned the news, he drove the delivery truck of the meat factory to take Du Xiangdong out of the isolation room.

Zhang Xiangyang thought that Xu Wenguo killed Chen Su'e, and Xu Wenguo's fingerprints were extracted at the scene. Du Xiangdong thinks that Xu Wenguo only went to the scene, and it does not mean that Chen Su'e was killed by him. However, the director thought that the criminal police team was in charge of solving the case, and he was not allowed to take care of it.

Du Xiangdong wanted the director to help him transfer him to the criminal police team to solve the case, but the director only wanted him to be a stable correctional officer and didn't want him to go to the criminal police team. But Du Xiangdong's future is still influenced by Xu Wenguo, and the evaluation of the title basically has nothing to do with him.

但杜湘东一直没有放弃徐文国的案子。他经常买东西去看崔丽珍，向她打听徐文国回家的动向。有一天杜湘东收到一张汇款单，汇款金额是三千元，杜湘东感到是徐文国汇来的钱。

He felt that there was news from Xu Wenguo, so he went to inform Zhang Xiangyang and asked him to find out Xu Wenguo's whereabouts. Zhang Xiangyang didn't want Du Xiangdong to meddle in his affairs, and told him that the case of the Sixth Machine Factory had been closed, and he still reported to the captain of the criminal police that he was going to arrest Xu Wenguo.

Although Du Xiangdong didn't believe that Xu Wenguo killed Chen Su'e, he wanted to investigate the truth of the case, but as soon as he had clues, he still informed Zhang Xiangdong as soon as possible and asked him to send someone to arrest Xu Wenguo. He said that Wang Hongbing was Xu Wenguo, and he wanted Zhang Xiangyang to trust his judgment.

Du Xiangdong had been to the Sixth Machinery Factory, but his investigation was complained by Liu Guangcai, the head of the security section there, who had to rely on his classmate Zhang Xiangyang to investigate Xu Wenguo's killing of Chen Su'e. Therefore, he often went to Xu Wen's country to find out his movements. Although Cui Lizhen would not tell him where Xu Wenguo was, he noticed that Wang Hongbing was Xu Wenguo from a remittance slip sent to Cui Lizhen.

Du Xiangdong has always wanted to investigate who killed Chen Su'e, but Zhang Xiangyang could not solve this case, because this case was obviously related to Liu Guangcai, the head of the security section of the Sixth Machinery Factory. On the day of Yao Binbin's cremation, Liu Guangcai heard the news of Xu Wenguo's return, and estimated that Xu Wenguo would go to Guancheng to find Chen Su'e for revenge, so he arranged for someone to kill Chen Su'e in advance, which not only played a role in extinguishing the mouth, but also blamed Xu Wenguo.

Chen Su'e died, Xu Wenguo was wanted as a suspect, and Tang Yaoxin could marry Sun Yonghong justifiably.

In order to achieve his goal, Tang Yaoxin laid off Sun Yonghong's family, and also canceled Sun Yonghong's qualification to participate in the dance team.

Sun Yonghong's family was laid off, and Tang Yaoxin used all the means to achieve his goal.

Tang Yaoxin bribed Liu Guangcai, the chief of the security section, and asked him to do bad things for him, first killing the workshop director Li Chao and blaming Yao Binbin, and then killing the witness Chen Su'e and blaming Xu Wenguo. After he got rid of Xu Wenguo, he forced Sun Yonghong to marry him, Sun Yonghong wanted to commit suicide, but because his family was laid off, he had to compromise with Tang Yaoxin and marry him.

Du Xiangdong couldn't get in touch with the inside story of the Sixth Machine Factory, and he couldn't investigate the truth when he went to the Sixth Machine Factory. In order to solve the case, he begged the director to transfer him to the criminal investigation team, but the director didn't want him to leave at all. He asked Zhang Xiangyang for help, but Zhang Xiangyang heard one side of the case, and based on Chen Su'e's testimony, he hastily determined that Yao Binbin killed Li Chao, and according to Xu Wenguo's fingerprints at the scene, he also judged that Xu Wenguo killed Chen Su'e.

Sun Yonghong was forced by Tang Yaoxin to compromise and marry him. And Tang Yaoxin, in order to chase Sun Yonghong into his hands, did not hesitate to kill people and create unjust cases. For Du Xiangdong, this fact is completely in the dark, no one will tell him, even if he knows, no one will believe him, because he is just a discipline and has no right to solve the case.

He launched a follow-up investigation into Xu Wenbin, and he found Xu Wenguo's traces from a remittance slip. But in order to find out the real culprit who blamed him and Yao Binbin, Xu Wenguo would not be caught so easily. Zhang Xiangyang was simple-minded in handling the case and careless about human life, Du Xiangdong only sympathized with Xu Wenguo and Yao Binbin, and could not do anything about the investigation of the case, but only listened to Zhang Xiangyang's conclusion and allowed the unjust case to happen again.

Perhaps, after Sun Yonghong marries Tang Yaoxin, he will find out the truth about the two murders from Tang Yaoxin's mouth, and find out how Tang Yaoxin conspired with Liu Guangcai to get rid of Xu Wenguo and achieve the goal of dominating her.
