Li Ming, a graduate student in the Department of Modern History, accidentally passed through the body of a poor official from the Dajing Dynasty. At that time, the government's policy was weak, party struggles were fierce, there were natural and man-made disasters inside, and there were powerful enemies outside. Fortunately, he found that he could clearly recall the vast amount of historical data and academic opinions in his mind. Relying on this "prophetic" advantage, Li Ming changed his name to Li Chen and stepped from the imperial examination room to the turbulent court. He used historical knowledge to predict crises, avoid traps, make friends with future famous ministers, put forward forward-looking reform suggestions, and rose up hard in the cracks between clear and turbid currents. He had to fight against the entrenched vested interest groups, balance the forces of all parties, and protect himself from the suspicion of the imperial power. In the end, he left a mark in the history of Dajing with the belief of "creating a life for the people and creating peace for all generations."
