Lin Han was killed by Gao Mingyuan because he knew Gao was not dead. Mai Gigi Lai met Gao He who was sentenced to death in the street. He told his classmates about it, and Lin Han went to the hospital to check it out. Gao Mingyuan found Lin Han after knowing it, and wanted to block Lin Han's mouth with 300,000 yuan, but Lin Han refused, and Gao Mingyuan killed his heart.

Gao He is Sun Xing before plastic surgery and identity change. He killed someone. Gao Mingyuan and He Yun struggled to save him, but Mai saw Gao He in the street and Gao He got into Gao Mingyuan's car. He was surprised, and then he met his classmate Lin Han and told him about it. As a policeman, Lin Han was keenly aware of this wrong thing, so he went to the hospital to investigate the matter, and the result was known by Gao Mingyuan.

Gao Ming went to find Lin Han and brought 300 thousand. He hoped that Lin Han would leave this matter alone after receiving the money, but Lin Han was a just policeman and would not be bought by Gao Mingyuan's money, so Gao Mingyuan sent someone to kill Lin Han, then pretended to be drunk and accidentally fell into the river, and put 300,000 cash in the trunk of his car to slander him.
