I Took Doubao Through the Ming Dynasty and Created the Prosperous Age of Hongwu

Dressed as a low-level blacksmith in Hongwu, I carry an almighty AI bean bag with me! Blueprints, medical skills, and farming techniques are all available, directly erasing all historical tragedies in Hongwu. Retain Zhu Biao, protect the heroes, appease the suspicious Zhu Yuanzhang, reform the world, and voyage to expand the territory. Don't get involved in political intrigues, don't open a harem, build a strong country with infrastructure + warm daily life, and create a perfect prosperous era!
