Wu Zhe, a double major in modern history and engineering, was accidentally electrocuted and traveled to the Dayin Dynasty, where he became the ninth prince who was despised by his father and despised by the court officials. At that time, Dayin was experiencing internal and external troubles: the court was controlled by powerful ministers, the princes were fighting for the throne and there was a bloody storm; local famines continued, and refugees were everywhere; the barbarians in the north were eyeing him, and the vassal kings in the south were separatist and independent. Wu Zhe, who had accumulated knowledge for two generations, started from a barren border land and used modern thinking to break the situation: improving agricultural tools to alleviate the food shortage, firing cement to build infrastructure, forging firearms to strengthen the armament, and innovating official governance to win over the people. He worked step by step, counterattacked from an abandoned son on the border to become a new noble in the court, fought his way out of the chaos of seizing the rightful son, and finally ascended the throne as emperor. Then he rectified the mountains and rivers, drove away the barbarians from the outside, and pacified the common people inside, creating a "Great Age" that incorporated ancient and modern wisdom, economic prosperity, and military power, and wrote a legend of "a modern academic tyrant turned into an emperor for the ages."
