Being with you is like being with a tiger. He is the most trusted son-in-law of Zhu Yuanzhang. Why was he killed after Judy usurped power?
When Judy launched the war of Jingnan, Main was transferred to Huainan, which was the only way for Judy's army. Judy can't move as long as Main stays there. Later, Judy's army really suffered a big loss in Huai 'an. Judy hates Main, but he has no choice but to make a detour and find another way to go to Nanjing. Although Maine knew Judy was going around, he didn't send troops to intercept or support the emperor. The final result was surprising, because Judy succeeded in usurping power. He drove out Zhu Yunwen and became emperor himself.
Although Judy became emperor, many people were dissatisfied with him, but he could only obey, and the beauty was different. Main not only complained a lot about Judy, but also refuted Judy many times, which made Judy very angry. However, in order to show his generosity of loving the people and caring for people, he did not suppress Mei Yin too much on the surface, but still hired Mei Yin. In the eyes of many people, this seems to be harmonious on the surface, but everyone knows that it is already very rough in the back.
With a king like a tiger, the emperor's heart is hard to guess, rain or shine. If he is not careful, he will anger the feast and get himself killed. Main's behavior has long made Judy want to destroy him, just looking for opportunities. During his first visit to the DPRK, Maine was pushed into the water by the emperor's cronies and drowned. No one could have imagined that an important official should have suffered such a disaster, and the final outcome was extremely tragic. In the eyes of many people, Judy killed Main, which is unkind. However, put yourself in others' shoes. If you were the emperor, would you tolerate such courtiers? I think everyone is unwilling. Judy actually did something meaningful in order to stabilize her position.
