As a front-line policeman, Li Chengyang was constantly attacked and framed by the umbrella of evil forces, and even his immediate boss, the public security bureau chief and others were imprisoned, unable to stop the investigation.

But in the end, under the command and leadership of the Central Political Commissar and the Central Supervision Team, Li Chengyang regained his freedom and joined hands with various departments of the Public Security Law. Finally, he eradicated two gangs of evil forces that had occupied Zhongjiang for more than ten years, brought the umbrella of evil forces and those corrupt officials to justice, and restored Zhongjiang with a clean political ecology and a clear social environment.

Gao mingyuan's personality analysis;

Ming-Gao Yuan is ruthless and unscrupulous. Whoever stands in his way will die. Ming was related to Ma Shuai's death, Mai's disappearance and Cai Ba's case. When Mai was killed by Dong Yao and Ma Shuai, the manipulator behind this incident was actually Ming-Gao Yuan. Chen Jianbo helped bury the body and followed Ming's instructions.

He Yun was able to sit on the position of deputy director of Lvteng City Public Security Bureau, which was operated by Gao Mingyuan, so He Yun was one of Gao Mingyuan's umbrellas. She participated in the resurrection of Gaohe and the sudden death of Ma Shuai.
