Li Shumin, the son of Ningqiang Security Chief Li Tianbing, and the nephew of the "hero" He Futang. He Futang was brought up by his sister He Fuying since he was a child, so he respected his sister very much. Of course, he also loved his sister's son Li Shumin particularly, and regarded him as the "pearl in his eye". At that time, the Li family was the richest man in Guangping, so Li Shumin was a high-end and classy "rich second generation" of the Republic of China.

Li Shumin is simple and kind-hearted, without any formality. She is 70% similar to her uncle in appearance and slightly similar in character to her uncle, but she is more simple than sincere. Li Shumin is still an infatuated person, deeply in love with the cold killer Cheng Lishan, and he pursues love at all costs. He was eventually used by Wei Zhengxian and his lover Cheng Lishan as a tool to deal with their uncle He Futang and the People's Liberation Army. Although He Futang hated iron but not steel, he still regarded him as the "pearl in his hand", so he always had scruples when dealing with the people Li Shumin loved, and gave in to Li Shumin again and again.

With justice on one side and her lover on the other, Li Shumin fell into a dilemma of choice. In the end, Li Shumin finally came to his senses and used his affection to influence his lover to surrender to the People's Liberation Army.
