The Steam Age of Ming Dynasty

I saved my mother first, then my father, and after I saved my grandma, I saved my grandpa. I am a researcher at the undergraduate college and reincarnated as a saintly grandson. Hongwu loves me more than treasures, and my family changes their lives and relies on me. I love inventing and creating. My grandfather loves me and lets me do it. He has established various research institutes covering all scientific and medical categories. Alcohol glass antibiotics, medical conditions are a big step forward. Sweet potatoes and corn are planted in the fields, and the people are relieved of hunger and look good. Land reform was in progress, productivity increased significantly, the Ming Dynasty had cannons and guns, and vassal kings guarded the borders overseas. From generation to generation, we have stayed in foreign lands, and in ten years and a hundred years we have become our hometown. The emperor of Ming Dynasty has steam engines, ocean-going warships bully the enemy, the products of all countries are dedicated to China, and all the people in the world are respected.
