[Great Ming + rebellion + reforming Great Ming institutions + ruling the world]
The protagonist was a leading weapons researcher in Longguo. One night, he was assassinated by American agents and his soul transmigrated into the Great Ming dynasty, becoming Zhu Zhi, the fifteenth son of Zhu Yuanzhang and Prince of Liao, in Liaodong. He bides his time until Zhu Yuanzhang dies and the Jianwen Emperor takes the throne, then kills the Jianwen Emperor's envoy and supports the Prince of Yan's rebellion.
After the Prince of Yan's victory, he takes the soldiers from Liaodong and elsewhere back to the Central Plains.
More than two years later, the Prince of Yan regrets it and dispatches feudal princes from every region northward. In the end, they are defeated at the Liao River. The Liaodong cavalry then heads south. Zhu Di panics and orders people to breach the Yellow River dikes, causing floods and devastation for a thousand miles. The people grow resentful of Zhu Di and, together with the Liaodong cavalry, form a peasant army to fight the Yan dynasty. The Marine Corps captures Yingtian.
The Yongle era ends just like that. The Prince of Liao then ascends the throne in Beiping and begins a four-year struggle against the false Southern Ming regime, led by Zhu Zhanji, which has moved south.
Zhu Zhanji jumps into the river at Guangzhou Bay and drowns himself.
In the process, I
usher in the Age of the Seas, and the nations of Western Europe one after another submit to me.
