Lanling Long Song: Entering the Battle Song

[Historical conspiracy + time travel + fate change + father-son love] Gao Yuanlang, a graduate student in the Department of History, traveled through time and became the only son of King Gao Changgong of Lanling. He was familiar with history books and had only one idea: to save his father who was about to die. There is no system, no gunpowder, only the rationality of thousands of years of knowledge and the step-by-step chess game. After ten years of dormancy, he walked from the dark alleys of Yecheng to become the Lord of the World, helping his father end the troubled times and unify the north and the south. The Dragon Throne was just around the corner, but he chose to give in - rewrite history, but not become a god.
