Grandfather Emperor, Are You Trying to Kill My Whole Family?

In the twenty-fifth year of Hongwu, Crown Prince Zhu Biao dies. Zhu Yuanzhang plans to name Zhu Yunwen crown prince, but just then Zhu Yuntong transmigrates into the past and decides that he has to fight for the throne. Otherwise, after the Three Fools of the Jianwen era make a mess of everything and his fourth uncle, Zhu Di, launches the Jingnan Campaign, he won’t even get the chance to live carefree as a prince when the enemy is at the gates. So, during the investiture ceremony, Zhu Yuntong draws his sword and storms into court, demanding of Zhu Yuanzhang: “Grandfather, are you trying to have my whole family killed?”
