"All of this seems reasonable at first glance, but you don't have concrete evidence on either the first supervisor or the North vanquishing Prince.
"The North-guarding King has been guarding the border all year round. I don't know him well, and neither do you. It was a little arbitrary to judge him with ill intentions.
besides, North vanquishing Prince is a third-rank martial artist. It's not impossible for him to reach second-rank in the future. It's hard to say if he's willing to be the Emperor. Hehe, of course, since ancient times, power has always moved people. If I say that he won't rebel, it would be arbitrary." Daoist priest Golden Lotus analyzed.
