What if the author suddenly decides not to finish the series? Reading the historical spoilers here and there, the events ahead seem to be "painful" to imagine.
For example, the whole Ei Sei turning insane, Shin having conflict with Ei Sei, Ou Hon sinking capital, Mouten being executed, etc.
So far for the series, it seems like, no matter how hard the enemies were, either it is Riboku and Houken, or Coalition Army, or internal conflict with Chancellor Ryofui and Queen Mother; so far all the good guys are going united and going together hands in hands. But the events ahead, seems the "good guys" will conflict with each other. Some faces will turn heels. So I can imagine it is very hard thing to do for the author to continue the series. To make fans' beloved characters turning into bad guys, to shatter the yearly friendship of Sei and Shin. It will be hard to draw compared to usual story.

Mangaka frequently do this type of thing where they flip an established story on its head, and Sei becoming evil is clearly where Hara has wanted to go with things from the start. I wonder if he knew how popular Kingdom would become, but Hara certainly knew evil Sei was going to be a thing. Lol
