Guan Hongfeng went to Xiguan alone with a heavy heart, looking for Lu Mingjia and going to the morgue to check Lin Jiayin's body, feeling full of guilt and self-blame.At the same time, Guan Hongyu was busy doing housework at home. Seeing the childhood photos of the two brothers, he couldn't help but smile. Although he was still a little dissatisfied, family affection finally defeated resentment.

In the hospital ward, Guan Hongfeng and Zhou Xun carefully checked Gao Dong's mobile phone. From the chat records and photos, it was not difficult to see Gao Dong's deep feelings for his fiancée Zhang Yahong.However, such a beautiful relationship may become Gao Dong's motive for murder, because any man can't stand his brother's violation of his fiancée.

Faced with the questioning of Zhou Xun and Guan Hongfeng, Gao Dong finally broke down and cried bitterly, admitting that he had gone to Gao Lei to ask about Zhang Yahong's whereabouts, but Gao Lei remained tight-lipped.Gao Dong said that he had never thought about killing anyone, especially his brother. Even if Gao Lei did something wrong to Zhang Yahong, he had never thought about forcing Gao Lei to death because they were brothers born from the same roots.

Gao Dong's cry deeply touched Guan Hongfeng and reminded him of the brotherhood between himself and Guan Hongyu.Therefore, Guan Hongfeng believes that Gao Dong is definitely not the murderer. The truth should be that after Gao Lei killed Zhang Yahong, he chose to commit suicide because he was too embarrassed to face his biological brother.Zhou Xun agreed with Guan Hongfeng's judgment and noticed that Guan Hongfeng seemed to have changed a little, becoming less cold and the brotherhood made him softer.Zhou Xun persuaded Guan Hongfeng and Guan Hongyu to resolve their conflicts and not let the misunderstanding continue to spread.

Back home, Guan Hongfeng took out a box from the drawer containing physical evidence related to his case.He apologized tearfully to Guan Hongyu and confided his true thoughts, and the brothers finally settled their differences.The next day, Guan Hongyu bought two fish and put them in the fish tank, symbolizing his relationship with Guan Hongfeng.Guan Hongfeng handed the portrait that Han Bin gave him to Guan Hongyu, saying that the murderer of Lin Jiayin was probably this baby-faced man, who was good at using the steel string in his left cuff as a weapon.If one considers that the entire incident was controlled by a certain force within Changfeng's jurisdiction, then the car that hit Lin Jiayin was likely to be repaired or remodeled at an auto repair shop in Changfeng's jurisdiction.If we follow this clue, we may be able to find the whereabouts of Baby Face.

At the same time, when Zhou Xun checked the physical evidence retrieval record sheet, he discovered that Zhou Shutong returned Wu Zheng's physical evidence one day late.In order to prevent her from arousing in-depth investigation and suspicion by the Guan brothers, Zhou Xun found an excuse to transfer her to the Shannan Road Police Station.Guan Hongfeng expressed regret for this, because Zhou Shutong had always dreamed of becoming an excellent female detective.But Zhou Xun believed that doing more was better than doing less, and he did this to avoid further accidents.

After Guan Hongyu disguised himself, he visited a nearby auto repair shop for investigation, and cooperated with Guan Hongfeng to find information about Audi cars.Just when it was getting dark, Guan Hongyu received a call and learned that a new case had occurred, and he immediately rushed to the station.The Shi Bureau told everyone that a case of human traffickers abducting children occurred in Tianjin and Hong Kong. The superior leaders put pressure on the case to be solved within a time limit, otherwise it would affect the evaluation of civilized cities.Before the meeting ended, Director Shi said that he would be on duty 24 hours a day and urged everyone to be prepared to work continuously in order to recover the abducted children as soon as possible.
