[No system + Rigorous + Emperor + Black-bellied + Killing + Reversal] In the twenty-fifth year of Hongwu, Zhu Yunhuan, who traveled through time, found out: Old Zhu died early? Well, it would be a waste to let Zhu Yunwen sit on the throne, so I'll take it! However, Zhu Yunhuan didn't know. Zhu Yuanzhang actually faked his death to test Zhu Yunwen. "What? Zhu Yunhuan ascended the throne!?" "Still want to reduce the power of the vassal states? Someone... wait, let's hear what he says!" "We forbade the sea but he wants to go out to sea? Come on... no, there are so many good things overseas?" "..." After waiting for a while, Zhu Yuanzhang felt that he could not wait any longer. In the morning court, seeing the "resurrected" Zhu Yuanzhang sitting on the dragon throne, Zhu Yunhuan was confused, and then a faint smile appeared on the corner of his mouth: "Grandpa Emperor, please make way, you can sit on my dragon throne."
