Episode 4 recap: Wang Ping issued a warning.

Yang Si was brought here, and Yang Si claimed that after he killed someone, he threw the gun somewhere in this area. However, it was dark at that time, and he himself didn't know exactly where he threw it. Guan Yu instructed people to search inside in groups, but they only found a piece of clothing and couldn't find the gun.

Yang Si insisted that he indeed threw the gun here, but as for the specific location, they would have to find it themselves. Yang Si wanted to smoke, but Guan Yu had quit smoking. Still, he took a cigarette from someone else and gave it to Yang Si. Guan Yu mentioned that Yang Xue Song was just Yang Si's stepson, so would Yang Si really seek revenge for him just because he was beaten?

Yang Si stated that whether or not Yang Xue Song was his own son, hitting Yang Xue Song was like hitting his own face. Moreover, that bastard Feng Gen burned his own house. Guan Yu asked if Yang Si knew what it meant for him to take action this time. Yang Si replied that he heard they use needles now, so it shouldn't hurt much. He couldn't swallow this anger, and since they didn't want him alive, then nobody should live.

Guan Yu instructed Zhou Qi to carefully review Yang Si's file from childhood to the present, take Yang Si to retrace the route he took, and asked Zhong Yi to check the surveillance footage. Yang Si explained that when he came out and went to the Hongqiao Group to find Feng Gen, there was a security guard at the door who initially didn't want to let him in. However, he killed that security guard, went upstairs, and met Yang Hongqiao, who said that Feng Gen wasn't there.

During their dispute, Yang Hongqiao even pulled out a gun.

However, Yang Si quickly took away the gun, and he fired two shots, killing Yan Hongqiao. Guan Yu asked Yang Si why he spared Chen Xiaoming. Yang Si explained that he didn't intend to spare Chen Xiaoming; he actually wanted to kill him. Unexpectedly, Chen Xiaoming couldn't handle the pressure and jumped off the building, ending his own life. Zhong Yi and the others found surveillance footage near a shop entrance and checked it. They discovered that Yang Xue Song did indeed have a conflict with Feng Gen and his group at that time.

Later, Guan Yu asked the taxi drivers in the area about the situation. They mentioned that Yan Hongqiao and Feng Gen had a conflict, and Yan Hongqiao dealt with Feng Gen quite harshly. Feng Gen used to manage the taxi company and took more commission than he should have, so Yan Hongqiao beat him up. Yan Hongqiao stated that the Hongqiao Group was a legitimate company, and they should only collect the appropriate amount of commission. Feng Gen dared to ask for more, disrespecting Yan Hongqiao. As a result, Yan Hongqiao handed over the management of the taxi company to Ma Xiao Jing.

Wang Ping received a call from the county mayor, who assured her that there were no issues on her side. However, the mayor wanted her to handle the case herself because it would be difficult to explain if the case was taken to the new district. Wang Ping summoned several executives and gave them a bank card, explaining that Yan Hongqiao had been making money with them, but the development of the new district was the Hongqiao Group's affair and had nothing to do with them. The card contained 1 million yuan, and she asked them to withdraw from the project.

The executives responded rudely, suggesting that Wang Ping, being a woman, should find a man to stay at home and take care of children instead of getting involved in so many matters. However, Wang Ping had already obtained evidence against them and had her assistant present it to them. She clarified that this matter originally concerned the Hongqiao Group and had nothing to do with them. Previously, Yan Hongqiao was willing to make money with them, but now she asked if they still wanted to be involved in these matters.

These individuals were aware that Wang Ping held leverage over them, so they dared not speak further.
