Looking for a book with a lich protagonist or something. Haven't seen that theme in very many novels. I'd like the story to have a pretty sizable series, atleast 50 chapters if it's a webnovel. If it's a translated novel I probably already read it.
Necrotourists: The Undead Living the Life Spoiler: link https://royalroadl.com/fiction/10211/necro-tourists-the-undead-living-the-life
Van from The Death Mage Who Doesn’t Want a Fourth Time Not a skeleton but a Dhampir should probably count as undead.
The Experimental Log of the Crazy Lich i second this. and "is it reincarnation if im dead" on rrl is pretty good (though he isn't op yet, just very talented)
Two Necromancers, a Bureaucrat, and an Elf. Not an undead protagonist but plenty of undead in the novel also it's a lot better than 99.9% of the translated novels. Also Johannes Cabal the Necromancer is better than everything on this website but doesn't contain many undead. Also good writing has no overpowered characters so there is that.
