Chinese Glory

In the last years of the Ming Dynasty, natural and man-made disasters continued. With the worries of peasant rebels inside and the Manchu cavalry outside, the rule of the Ming Dynasty was on the verge of collapse. By chance, a modern man comes to this era that does not belong to him. He carries neither advanced modern instruments nor sophisticated modern weapons, nor does he have any extraordinary powers. He is just an ordinary military enthusiast, and what he has is just the modern knowledge possessed by an ordinary modern person. Once here, everything is up to him! Reading history from books is one thing, but experiencing it personally is another thing. Where should he go from this familiar yet unfamiliar history? Should we follow the so-called "historical trend" and live a prosperous life, with a wife and a son? Or should we use this as an opportunity to turn the tide and revive China's glory?
