Daming: I Turned Things Around in the Hongwu Dynasty

Zhu Xuan, a modern librarian, accidentally traveled to the Hongwu decade of the Ming Dynasty and possessed a poor boy who died of starvation. He originally wanted to live a peaceful life in the countryside, but due to his "theory on the rise and fall of dynasties", he was caught by Zhu Yuanzhang who was visiting privately incognito. What's even more bizarre is that Zhu Yuanzhang was shocked to find that according to the genealogy, this boy was actually his legal uncle!
