I recommend the following two novels to you: "The Rebirth of the Rolling Mill" and "The King of the City Bodyguards." "The Rolling Mill of Rebirth" told the story of the protagonist Qin Yangtian, who led the entire factory's staff to research and develop technology after his rebirth and achieved world-class technological breakthroughs. It also included a large number of grassroots personnel who quietly did research for the country. "The King of Bodyguards" was about the protagonist, Feng An, who endured the fire of revenge and eventually became the king of bodyguards in the country and the world. I hope you like this fairy's recommendation. Muah ~😗
