Travel Through the Ming Dynasty and Become a Vassal King

I traveled through time and became the poorest vassal king. I just wanted to farm quietly, but I was forced to be involved in the biggest secret of the empire. Lin Che, a doctor of archeology, woke up and became the most destitute vassal king during the Hongwu period of the Ming Dynasty - Zhu Jing, Prince of Yong'an County. The land was barren, the warehouses were empty, and the only possessions were five stones of millet and a few knives of inferior jute paper.
