Episode 2 recap: Cheng Bing returned without achieving anything.

To evade the police pursuit, Wang Da Yong continued to flee with his younger brother, Wang Er Yong. They took advantage of the nighttime and ran to their brother's house, hoping for assistance. During the day, police cars were patrolling the streets, and Pan Da Hai continued his investigation with Cheng Bing to track down the murderer. Pan Da Hai was deeply concerned about the situation and spoke with eyewitnesses. After hearing their accounts, they quickly determined that Wang Da Yong had been in the car with his younger brother.

After observing from the sidelines for a while, Cheng Bing began using unconventional methods to analyze the case. He started to believe that the killer had no intention of fleeing and was still hiding in the city. This meant there was still a chance to apprehend them. At this point, Cheng Bing was ready to help his good friend remove the burden from his heart. However, Pan Da Hai couldn't let go of his pride and continued to argue with Cheng Bing.

Meanwhile, Wang Da Yong and his younger brother had no plans to escape. They sought refuge in an old friend's house. During the daytime, Wang Da Yong's brother expressed concerns about betrayal, but Wang Da Yong firmly believed that his friend wouldn't dare to do so because of the seven murder cases he had been involved in.

After finishing the inspections on the streets, Cheng Bing didn't forget to conduct door-to-door interviews with others, not letting go of any suspects. Finally, in the internet cafe's surveillance footage, he spotted two figures. Based on these clues, Cheng Bing confirmed that Wang Da Yong and his companions were still in the city.

Taking advantage of everyone being asleep, Xiao Liu silently placed a blanket over Wang Da Yong and started questioning his intentions. Wang Da Yong realized that Xiao Liu was worried about him leaking information, so he assured him that he would keep everything a secret. Then, without hesitation, Wang Da Yong took out a gold chain and sought Xiao Liu's help.

After leaving, Xiao Liu took the gold chain that Wang Da Yong had given him and planned to exchange it for money. Wang Da Yong understood that Xiao Liu urgently needed money, so he reluctantly agreed to accept it. On the other hand, Cheng Bing concluded that the perpetrator had left all the cash at the crime scene, and the only valuable item they had was the gold chain around their neck. Without wasting time, Cheng Bing instructed others to prepare for investigations at various stores.

After successfully exchanging the money, Xiao Liu counted it several times and brought it back. Wang Da Yong, sitting beside him, understood the hardships his old friend had been through. He generously gave him a significant portion of the money and agreed to let him see the real gun he had. Meanwhile, Cheng Bing made a special trip back home. Quietly going upstairs, he took the initiative to check on his daughter, who was lying in bed. When his daughter saw him return, she excitedly grabbed his hand and they went to eat cake together. Cheng Bing saw his daughter's concern about him and his wife, and he solemnly vowed that he would never divorce. However, his wife quickly emerged and took their daughter inside to sleep, completely ignoring her husband.

Having been rejected, Cheng Bing had to sleep on the couch that night. The next day, he woke up early and went to buy food for his family. While in the kitchen, his wife suddenly brought up their conversation from before. Cheng Bing immediately disagreed and, after finishing the call, prepared to resume his investigation.

Upon meeting someone, Cheng Bing realized that they had melted the gold chain into gold bars. He interrogated them for a while until they confessed to the situation with the gold chain, providing a detailed description of the seller. After gathering this information, Cheng Bing discovered that the person depicted in the portrait was Wang Da Yong's friend. He immediately drove to the vicinity of his friend's house to prepare for an arrest. Meanwhile, Xiao Liu remained unaware of the situation and, when he was apprehended, he intended to continue protecting his accomplice. Cheng Bing confronted him directly, and in order to reduce his own culpability, Xiao Liu revealed his old friend's identity. However, when the police went to apprehend him, they found that he had already fled. At this point, Cheng Bing received a message from Pan Da Hai, which provided information about the murderer. But when they arrived at the location, they realized they had captured the wrong person, leaving them dejected and disheartened.

While sitting down to eat with Pan Da Hai, Cheng Bing suddenly felt that something was amiss about the events of the previous night. He began to ponder where the problem might lie when news arrived that the suspect had fled the neighborhood unexpectedly.
