In order to investigate the situation, Cheng Bing has been looking for electric vehicles, but has found nothing.After Cheng Bing left, the girl who lost the car and her husband appeared in the car.

When Cheng Bing returned to the inn, he found that the inn felt guilty for being retaliated against, and the boss fired Cheng Bing on the spot.When Cheng Bing left alone, he received encouragement from his colleagues and his confidence instantly doubled.

Wang Miaomiao's younger brother cracked down on fraud. After Wang Miaomiao took his younger brother back, he met the other parent who came to hold him accountable. He saw that the other party mentioned that the murderer lost control of his mood and wanted to beat him.After Cheng Bing received a call and learned about the situation, he took the initiative to contact Wang Miaomiao to give him good advice.

Late at night, Cheng Bing decided to go out to investigate the girl and did not forget to contact Pan Dahai.

In order to investigate, Cheng Bing became a water deliveryman and found the woman whose battery car was stolen by delivering water. However, due to the high vigilance in the woman's home, he was unable to enter and could only stay outside.

Cheng Bing squatted and noticed that the man in the house went downstairs and drove away. He immediately followed the man to a store. He wanted to extract fingerprints from the things the man touched, but found nothing.

Cheng Bing stayed at the case for many days, and finally found hair through the garbage at Anzi's house.

Cheng Bing was doing his daily job of delivering water. When he learned that Anzi had asked him to deliver water, he knew something was wrong. Then he noticed someone was following him while delivering water, so he secretly contacted Pan Dahai.

At night, Anzi followed Cheng Bing at work and wanted to attack him.Cheng Bing noticed that he was hiding in the door, and there were constant knocks on the door. After Cheng Bing prepared everything and went out and went downstairs, Pan Dahai led the police to arrive and arrested Anzi on the spot.

At the police station, Anzi refused to cooperate in the interrogation.It wasn't until Lin Ying got the DNA test report that she was sure that Anzi was Wang Dayong.

Cheng Bing was relieved to learn the situation and immediately sent the good news to everyone.​
