The Knockout

The Special Investigation Unit overseeing the rectification of sex education commences its work to establish discipline among civil servants in Jinghai City, including Xu Zhong and Ji Zhe.

Even after their meeting, Shizhong and Jizhe remain distrustful of An Xin, while Gao Qichang endeavours to project a favourable image to the special investigation team.

An Xin, Xu Zhong, and Ji Zhe visit the house where Gao Qichang once lived. Xu Zhong asks An Xin how he would act if he could return to the past.

The Major Crimes Unit devise a plan to wipe out Feng Lutz's gang, while Feng Lutz proposes to An Xin that they go into hiding together. Feng Lutz seizes An Xin's camera, which contains incriminating photographs.

After Xulei died from electrocution, Gao Qichang and the Tang brothers flee the scene, while An Xin witnessed Xulei's father confirming his son's death at the scene.

Bai Zhangbo reveals the identity of the murderer who killed his son to Xu Zhang, who then seeks revenge against Bai Zhangbo and sets his sights on the Tang brothers next.
