World of Cultivation- Intro arc is how this specific xianxia world works (pretty entertaining due to good worldbuilding) and after that its wartime. Archean Eon Art - its mostly human world invaded by demon world deal and why the war goes as it does. Its IET so protag eventually carries humans hard, but he works up to that gradually like an actual cultivator instead of hitting immortality at 15 like your usual brainless webnovel author suit. Can't remember anymore at the moment.

Oh, both have been translated by Skythewood. lol I didn't realize. I prefer the Youjo Senki manga so I've never finished the novel. That's probably why. But funny coincidence.
I second World of Cultivation. World War is the theme of the entire novel, basically a band of brothers trying to survive a world where all minor sects are drafted to be used as cannon fodder by the major sects (they're part of a minor sect of course)
