He Yong, the leader of the task force played by Liu Yijun, and Li Chengyang, played by Sun, were classmates of the police academy, and they had a very good relationship at the police academy. Everyone knows that Li Chengyang looks like a villain. In fact, he is also a policeman at heart. He left the police force after being framed.
And Liu Yijun is the leader of the planning team, so far, it's ok. However, the editor's brain circuit always surprises us, and the choice of the villain is unexpected. The reason why audiences like watching anti-corruption drama and crime-solving dramas is that they have one common feature, that is, they guess while watching the dramas.
As soon as He Yong arrived at Lv Tengcheng, he met an old acquaintance Li Chengyang, who was the opposite of him. He started all kinds of private investigations, first looking for the police, and then dug up Li Chengyang's basketball photos in Xinshuai Group, the company that He Yong investigated. So he began to compare Xing Fei, Li Chengyang's friend and their mutual friend in the film, and met privately to inquire about Li Chengyang's situation.
When Xing Fei affirmed that Cheng Chengyang had no problem, He Yong asked him whether he was familiar with Brother Chengyang or with him. According to normal people's thinking, we should choose to believe, because Xing Fei, He Yong and Li Chengyang are friends. He Yong was not happy for his former good brother when he heard that there was no problem. Instead, he questioned Xing Fei and asked Xing Fei to choose between the two. It is doubtful whether He Yong has any other purpose and wants to know the situation through Xing Fei.
The ending song also has a list of actors. Li Chengyang and He Yong are both at the top of the list. Generally, important people and TV protagonists will be in front. According to the current plot, we might as well boldly guess that he may be a villain.
