Lin Yue, a doctor from the Department of Modern History and Department of Engineering, accidentally traveled to the body of a scholar who had been in trouble for three years in Hongwu. At this time, the Ming Dynasty was facing internal and external troubles. Lin Yue relied on his advanced knowledge and accurate historical predictions to quickly seize the opportunity and win the appreciation of Zhu Yuanzhang. He counterattacked and advanced all the way, promoted reforms and revitalized the economy internally, mobilized troops externally, opened up territories, and assisted the rapid rise of the Ming Dynasty, laying a foundation that is far stronger than history.
