Episode 23 recap: Wang Da Yong was arrested.

Cheng Bing saw a person carrying a package that looked exactly like the thief's bag when they came to send a package and informed the police. They managed to dismantle a gang that stole electric bikes. The police were grateful to Cheng Bing and were surprised by his alertness. The police called a woman and told her that her electric bike had been recovered and asked her to come and claim it.

Ango asked the woman to go and send the package. When Cheng Bing returned to the delivery station, he found a package addressed to Huang Liping. He checked the surveillance footage and saw the electric bike. The boss told Cheng Bing not to get involved as they were just a delivery service. Cheng Bing quickly went to find the electric bike.

What Cheng Bing didn't notice was that behind him, Ango drove with the woman into the residential area. Cheng Bing arrived at the delivery station and found everyone there. The boss told Cheng Bing to leave quickly. Cheng Bing then realized that they were being retaliated against, and they were too afraid to get involved or report to the police.

Cheng Bing resigned and his colleague followed him out, saying that the boss had printed out a photo of the woman and asked everyone to help find her. They believed Cheng Bing was a good person, and there would surely be a good outcome. Cai Bin's son got into a fight with a classmate, and Cai Bin and Wang Miao Miao rushed over.

The classmate's mother spoke very harshly and believed that Cai Bin's son would grow up to be a murderer. Wang Miao Miao rushed forward and hit her. Cai Bin called Cheng Bing and told him about the situation. Now Wang Miao Miao locked herself in her room and refused to eat, feeling that they shouldn't help pay compensation.

Cai Bin said that Wang Miao Miao listens to Cheng Bing, so he asked Cheng Bing to persuade her. Cheng Bing talked to Wang Miao Miao about the incident, expressing that it was wrong for her to hit someone and asked her to go outside and see for herself. Cai Bin and his wife were still waiting for her to have dinner.

Wang Miao Miao opened the door and realized that it was indeed the case. She didn't expect them to treat her so well and admitted that she was truly in the wrong. Cheng Bing told Pan Da Hai about the current lead and said he would continue investigating.

Cheng Bing accidentally discovered that water delivery workers were allowed to enter people's homes, so he found a job as a water delivery person. Cheng Bing also organized a promotional activity, going door to door to distribute water vouchers, and finally found the place where the woman lived. However, Ango wouldn't let Cheng Bing in and he had to wait outside the building. Finally, when Cheng Bing saw Ango coming out, he quickly followed him. Ango entered a pipe shop, and Cheng Bing went inside to make a purchase, coming face to face with Ango.

Cheng Bing pretended to buy a faucet, and Ango kept holding onto a screwdriver. Cheng Bing called Pan Da Hai and told him that even though he didn't look like it, he knew at a glance that it was Wang Da Yong. He managed to get Ango's fingerprints and asked Pan Da Hai to decide whether to test them or not.

Unexpectedly, the test results only showed Cheng Bing's fingerprints. Cheng Bing remembered that Ango had an injured finger and didn't have any fingerprints. After Ango returned home, he checked the news and found out that Cheng Bing had been imprisoned. Cheng Bing went to Ango's doorstep, took their trash, and found some hair, which he sent to Pan Da Hai.

Cheng Bing was supposed to go for a water delivery job, and the boss said someone specifically requested Cheng Bing to deliver to Ango's address. Cheng Bing noticed that Ango was following him. Pan Da Hai realized the danger in this and advised Cheng Bing to be cautious, but Cheng Bing felt that he couldn't hide either.

Pan Da Hai told Cheng Bing to be careful as they were on their way. Cheng Bing returned home and noticed that Ango was following him from behind. Cheng Bing took out a knife behind the door, and Ango knocked on a door, but it turned out that Cheng Bing wasn't inside. After Ango went downstairs, he saw that the police had surrounded the area and took him away. Ango denied being Wang Da Yong, and Pan Da Hai was anxious. Fortunately, at the last moment, Lin Ying arrived with the test report confirming that the person was indeed Wang Da Yong, and everyone breathed a sigh of relief.

Cheng Bing sent a message to everyone, asking them to come over. The members of the Third Unit were all very excited.
