- Introduction: A graduate student in the Department of Modern History travels back in time to become Zhu Youqian, the most miserable prince of the Zhengde Dynasty. His mother and concubine are humble, and he is weak. He cannot even have enough food and clothing in the palace. In a desperate situation, he activated the "modern knowledge base", which contained countless useful information on agriculture, military, technology, etc. In order to survive, he had to save the Ming Dynasty, which was suffering from internal and external troubles - he improved the bent-wheel plow, secretly promoted corn and sweet potatoes, and alleviated the food shortage among the people; he took advantage of the border crisis to form a new army, and used improved firearms to beat the Tatars; he joined forces with Shen Qingci, the daughter of the minister who was proficient in arithmetic, to promote new agricultural policies, gather people's hearts, and build strength. Faced with the suppression of the authoritarian eunuch Liu Jin, he worked step by step, united with upright ministers to bring down the traitors, and finally impressed the playful Emperor Zhengde with admiration. He became the core pillar of the Ming Dynasty's reform, and single-handedly brought the shaky dynasty back on track.
