When You're Emperor in the Yongle Era, What Do I, Zhu Di, Do?

Yao Guangxiao: Your Majesty, Emperor Jianwen has the demeanor of a great ruler. If you don't kill him now, your throne may be unstable! Zhu Di: Wait a bit longer. The Hongwu cannon with a range of over a hundred li is about to be built. Once it's done, I'll definitely kill him! Yao Guangxiao: Your Majesty, the super Hongwu cannon has been built. Why haven't you killed Emperor Jianwen yet? Zhu Di: Haven't you seen that our Ming Dynasty's first battleship is about to launch? Once it's launched, I'll kill him immediately! Yao Guangxiao: Your Majesty, Emperor Jianwen has already sailed the battleship and doubled the territory of the Ming Dynasty. If you don't kill him now, all the civil and military officials will think this is no longer the Yongle era! Zhu Di: Nephew Yunwen, your fourth uncle begs you, please come back and be emperor. I want to go to war... A man with the same name, Zhu Yunwen, travels to the fourth year of Jianwen, the day Zhu Di seizes power. To survive, he must use the system Doubao and modern thinking to create a different Ming Dynasty golden age!
