(No system + ancient hot-blooded strategy)
The history professor was reborn as Li Zhongxuan, the prince of the Southern Tang Dynasty. When he opened his eyes, the city of Jinling was destroyed. History books said that he would die and the Southern Tang Dynasty would fall.
However, he abandoned the city and went south, using modern knowledge to refine gunpowder, build sea ships, reform the imperial examination, and fight his way through the cracks between Song and Liao.
From being an exiled supervisor to becoming an iron-blooded emperor, he built a cabinet, unified the north and the south, collected Youyun, and ended the troubled times with his own hands.
When the dragon flags were planted all over the Central Plains, everyone in the court asked: "How does your Majesty predict the world's affairs?"
He smiled and said nothing, looking in the direction of a thousand years later.
——This time, history is written by me.
