For Li Yifei, today's incident was definitely unexpected, but since it happened, it doesn't necessarily mean it's a bad thing. At least Brother Hao could be of use to him in the future. Mile City includes Dawa, and his desire to be the emperor there is simply out of the question.
So as long as Brother Hao stays in Dawa, even if he is not directly under Brother Hu, a word from Brother Hu would be enough for him to get things done. And as for the big boss behind the scenes—himself—he naturally wouldn't dare to offend.
These underground forces are indeed not a good source for normal people, but since ancient times, such forces have never been completely eliminated. Li Yifei does not harbor grand ambitions to eradicate these forces, so making good use of them is his best approach for now.
