The First Duke of the Ming Dynasty

Traveling through the Ming Dynasty, the first year of Zhengde. The border post is broken and the scholar is poor. Chen Yuan, a graduate student in the Department of History, woke up and became a down-and-out scholar in Jimingyi who couldn't even eat. What was placed in front of him was not a poem about romance, but the scimitar of the Tatar cavalry outside the city wall! Know history? Then use knowledge to change your destiny! Making firearms? Then use dimension reduction strikes to crush cold weapons! Playing Machiavellian? The Eight Tigers, the civil servants, and the vassal kings are all the stepping stones for my advancement! From the ruined temple of Jimingyi to the splendid Fengtian Temple; From a poor scholar who relied on clay pots of tung oil to defend the city, to Duke Dingguo who commanded a hundred thousand new troops! Liu Jinquan is in power? I'll cut him into pieces! Is King Ning planning a rebellion? I will destroy him in March! Tatars drink horses from the Yellow River? I told him not to dare to go south for ten years! He also lifted the sea ban, developed firearms, and reformed the military system, turning the tide from collapse, supporting the generals of the Ming Dynasty, and turning the gloomy sky of the Zhengde Dynasty into a bright and prosperous world!
