The webtoon adapatation of it is really good and so I checked its LN right away after I saw the artist's note on this. It's manwha's title is The Lone Necromancer and so it took me quite long to realize that this is its own novel ? Though there is a difference on some plots between the novel and the manwha, I can say it has a pretty good story that fairly gives a proper setting for a character with a necromancer skill., even giving an in-depth and wider scope of possibilities and growth for a profession that is more likely limited only to necromancy.
