Apparently somewhat inspired by the Romance of the Three Kingdoms, and that might account for some of the unusual stylistic aspects, including a willingness to introduce characters on the fly and do away with them - including quite significant ones - with very little build-up or post-mortem lingering, as well as the handling of its characters more generally in a way that is slightly at arm's length. It's well written, if at times a touch simplistic in its treatment of character motivations and plot moves, and reasonably immersive - not to mention winning points for doing something a bit different, with its Asian-inflected but not reductionist setting - once it gets going without ever feeling all-enveloping in the way that the very best of this genre manages.
