Can you recommend a novel about rebirth in officialdom?

The protagonist was reborn as the third generation of the Red Army and secretly sought many benefits for the country (such as when the Soviet Union disintegrated). His credit and ability were not comparable to the other third generation children, but comparable to the second generation. There was a plot where some third-generation descendants provoked him, but he ignored them and easily defeated them with an open plot. He said that they were not qualified and directly talked to the other party's father. The big shots from all sides were secretly observing and praising him.
There was a man who had offended the main character and was used to establish his authority. He was slapped. The man's sister seemed to be called Li Mei. She led her troops out to surround the main character and even pulled out a gun. The main character caught him. In the later part of the story, the man always played dirty tricks on the protagonist

Answer 1

I recommend a historical fiction novel called "Dark Change of the Country." This novel told the story of a young and talented man who changed the world with a knife. The protagonist had the opportunity to display his talents in the officialdom and change the direction of history because of his rebirth. I hope you like my recommendation. Muah ~
