I remember that I have read a territory management novel, forgot whether the MC is actually chinese or japanese. But the world story is actually in ancient western. If I'm not wrong the MC's title is baron? Another thing that I remember that MC introduce how to process meat, create a building for slaves, introduce new crops. I don't remember whether this is actually a novel or only an arc. Oh yes, I suddenly remember that MC decided that punishment of someone wrong doing is to deal with excrement for soil, of course he does not say anything for soil..
