14 years ago, Dong Yao and Ma Shuai found Mai to mix the village-to-village communication project, but Mai didn't give any face and had to be reported. Dong Yao directly killed Mai Gigi Lai, and this matter was not discussed with Ma Shuai, so he went into the water directly.
After the incident, Chen Jianbo was invited out to dispose of the body through Gao Mingyuan's relationship. Chen Jianbo dumped the body directly under Anfu Bridge. Anfu Bridge is in the project of Yihe New Village, so this is why both Gao Mingyuan and Li Chengyang want this project.
On the other hand, in order to protect his son, He Yun became the kind of person he hated most. He Yun's son is called Gao He, which is Sun Xing who appeared at the beginning of the TV series. Sun Xing was sentenced to death after killing, but He Yun used his relationship to save his son and changed his name. He is taken care of by Gao Mingyuan and continues to be at large.
When Li Chengyang was in charge of the Gaohe case, his master Lin Han took him to investigate. After Gao Mingyuan discovered this incident, he directly killed Lin Han through an accident and framed Li Chengyang, which led to Li Chengyang being expelled from the police force.
Anyone who has seen this TV series should know Lin Hao, who is Lin Han's son. In order to know how much he knew about the death of Lin Han, He Yun felt that he owed him, so He Yun recognized him as his adopted son.
Later, after being framed and suspended in a nightclub in Sun Xing, Leo joined the task force. He Yun could not monitor Leo's actions, and Leo began to investigate Sun Xing.
In the latest preview, Li Chengyang cried when drinking alone, and there were three cups in front of Li Chengyang. These three should be the most important people of Li Chengyang, and they should be Lin Han, Ma Shuai and DJI. Both Lin Han and Ma Shuai are dead, so everyone should think about who the cup is for, and the river will eventually leave everyone's field of vision. The final outcome of this TV series may also be a tragedy. In order to eradicate evil forces, he gave his life.
