A good read, I'm a sucker for villain type protagonist that conquer/do shit.
My only problem with it would be the pacing, she goes pretty fast in getting stuff for her or her army with almost-to no explanation. I'll try to read the LN and see if it explains more cause while I don't like exposition for many things and prefer the author to show it instead, but here it didn't show much and explained pretty much nothing, be it the points she can use to strengthen herself or her servants, or certain items she can use (the magnus opus stuff, which relate to alchemy, is it something you get when you just learn alchemy? and how much levels does she has or are levels required to craft stuff like a philosopher stone, etc. or just ingredients?).
I know her servants are pretty useful but sometimes if feels like she gets stuff a bit too fast or out of no where (or maybe that's me reading too fast).
Anyway I'll now have to wait for the fall of the capital.
