Zaizhi Daming: I Lead the World's Scientific and Technological Revolution

When I traveled through time and became Zhu Yuan, the third son of Zhu Yuanzhang, I was establishing a vassal state in Taiyuan under the reputation of being a "tyrannical vassal king". The prince Zhu Biao has just passed away, the emperor's grandson is young, and his father Zhu Yuanzhang is getting old. And my fourth brother, King Yan Zhu Di, was staring at me with a dead look in his eyes - in history, it was he who forced the original owner into a desperate situation and died in depression. The knife of party struggle has been placed on the neck, and the bloody edict to cut down the feudal clan may come at any time. But this time, I will not fight for the throne or the throne. I want to use another way to let Ming survive.
