"Zhu Tianyu", a top student in the history department in the 21st century, was accidentally hit and killed by a runaway truck while compiling historical materials in the library. His soul traveled to Zhongli County in Haozhou at the end of the Yuan Dynasty and became Zhu Yuanzhang's cousin Zhu Tianyu. When the Red Scarf Army uprising broke out, the Yuan Dynasty was corrupt and the people were in dire straits. The protagonist relied on modern historical knowledge and socialist thinking to try to promote social change within the framework of the feudal system and work with Zhu Yuanzhang to rewrite the historical trend of the early Ming Dynasty. (Because it is a different world, it will be different from history, so characters like Xu Da, Chang Yuchun, and Li Shanchang will appear directly, so it will look a bit abrupt. Please do not read the novel with a harsh eye on history!!!)
