913 Serious Case Chase

On a rainy night in Beijing, the body of the third female serial murderer was thrown in a flower bed in the city center. There was an evidence card from an old case ten years ago on her chest. The police officers in the scene changed their colors. The protagonist, Lin Zhengfeng, is a veteran criminal policeman who has just been transferred back to the serious crime team. This old case ten years ago was supervised by his master. The master mysteriously fell from a building and died. The case was forcibly closed, and Lin Zhengfeng was even sent to a remote police station. The identity of the deceased was revealed to be a cross-city human trafficking syndicate, and the protection behind the scenes was Gao Tianci, a newly powerful man in Beijing, who was the driving force behind the closure. Lin Zhengfeng's investigation of the case was hindered at every turn. His teammates were bribed to anonymously report him for disciplinary violations, and his daughter was kidnapped and threatened. His fiancée Su Qingyao, a prosecutor, always stood by him and secretly helped him collect evidence of crimes against powerful people. Lin Zhengfeng followed the corpse dumping route to the cross-border dock den, broke into the den alone, rescued the abducted girl, and obtained the group's core ledger. Under internal pressure, he jointly removed the protective umbrella with the Disciplinary Inspection Commission and wiped out Gao Tianci's group. Finally, it was confirmed that Gao Tianci had killed and covered up the evidence, and the master and the deceased were redressed. Lin Zhengfeng also became the leader of the serious crime team and married Su Qingyao.
