This novel was called "Hero of the Forbidden Zone." The main character was called Chen Yingxiong. He led an army of millions at the border for ten years, and his wife was framed. I would like to recommend a novel with a similar theme,"The World of Traitors." It was also a historical novel. The protagonist traveled back to the Song, Yuan, and Ming Dynasties and tried to save the people from a thousand years of decline. I hope you like this fairy's recommendation. Muah ~😗
