I! the Orthodox Grandson of the Ming Dynasty

The protagonist wants the easiest way to succeed to the throne and tells Lan Yu what Zhu Yuanzhang thinks. At this time, Lan Yu will find that one of him and Zhu Yunwen must die. He represents the lineage of the Crown Princess Chang (Chang's mother is Lan Yu's sister). Zhu Yuanzhang is going to help Zhu Yunwen, so he must kill Lan Yu, an unstable factor. Lan Yu will definitely find a way to kill Zhu Yunwen if he finds out. Even if Zhu Yuanzhang knew about it later, he would not kill Lan Yu, and would at most imprison him. Because at this time the protagonist is already the first in line of the third generation, killing Lan Yu is equivalent to cutting off the protagonist's power. There was no fourth generation for Zhu Yuanzhang to establish. In addition, each of the second generations had troops. It was against the rules to establish them and could easily cause unrest.

Let me tell you something, Zhu Yunwen's mother is Lu, and brothers Zhu Xiongying and Zhu Yunxi's mother, Chang, is the Crown Princess. Later, Zhu Xiongying died. Normally, Zhu Yunxi would be the first in line, but the Crown Princess also died, and she died earlier. Zhu Yuanzhang straightened up the Lu family. Well, before Zhu Biao died, Lu family was already the second crown princess, so Zhu Yunwen was also the legitimate lineage. At this time, his grandson Zhu Xiongying had died, and Zhu Yunwen was older than Zhu Yunxi, so he was the first heir of the third generation, and it was natural to inherit the throne...
