What was the name of the novel in Li Yu's era? If I transmigrated to the Southern Tang Dynasty and became Li Yu?

Southern Tang New Era. I recommend this historical fiction novel to you. The main character, Li Congjia, is a military academy student. After transmigrating to the Southern Tang Dynasty, he transformed into Li Yu. Through making up prophecies, promoting martial arts, building a new army, and building a business road to accumulate wealth, he pushed the Northern Expedition to break the unification. He drew a magnificent picturesque landscape and showed the heart of a strong and rich man. I believe you will like this novel! I hope you like this fairy's recommendation. Muah ~😗
