The protagonist, Qin Mo, was a graduate student in the history department of the 985 University in his previous life. He is proficient in the rise and fall of Chinese dynasties and military strategy. After traveling through time, he became the last prince of the Great Xia Dynasty. He had a calm and decisive character, combining the rationality of a scholar with the decisiveness of an emperor. The initial situation was extremely difficult: his father died suddenly, powerful ministers usurped the government, and foreign tribes invaded the border. He fled to the border with only a dilapidated palace and three hundred old and weak soldiers. The growth arc goes from "survivor" to "hero in troubled times" to "destined emperor", tempering the emperor's mind in blood and fire, and finally establishing an eternal dynasty spanning three realms. The core contradiction is: he always remembers the law "all dynasties will eventually fall" in the history textbook, but wants to break this law in the fantasy world
