Zhu Yuanzhang Was Mad at the Beginning, but He Backhandedly Saved Queen Ma

Ma Zhengchun traveled through the first year of Hongwu and became Queen Ma's long-lost brother. Zhu Yuanzhang: "We will grant you the title of First Marquis of the founding of the country, with a settlement of 3,000 households!" Ma Zhengchun: "No interest. I want to open a medical clinic, build a laboratory, and repair sewers." Zhu Yuanzhang was furious, thinking that his brother-in-law had something in his head. But when Ma Zhengchun took out penicillin with his backhand, he changed his life and saved Queen Ma; a piece of "Epidemic Prevention Law" made the plague disappear; granules of gunpowder were sent to Chang Yuchun to become a god... Lao Zhu's defense was completely broken: "We just want to make him a marquis, but he teaches us how to make the Ming Dynasty immortal?" Ma Zhengchun: "Brother-in-law, the map is too small. The world is so big, don't you want to see it?"
