A graduate student in the Department of Modern History traveled through time and became a low-level county official in Qingzhou at the end of the Eastern Han Dynasty, which coincided with the outbreak of the Yellow Turban Rebellion. With his accurate prediction of the historical direction and modern governance concepts, he started from a dilapidated small county, cultivated crops, recruited talents, and organized the army. He worked step by step in troubled times, and finally embarked on a path to unification that was completely different from history.
