Dr. Ming Shi travels back to the end of the Ming Dynasty, and there are still 72 hours before the finale of Meishan. No system, no golden fingers, only 20 years of Ming history research.

The emperor guards the gates of the country, and the king dies in the country - but this time, I will not hang myself.
