The original novel for this fanfic is Blood Warlock: Succubus Partner in the Apocalypse by XIETIAN, and honestly, it's one of the best novels on this app (at least for me). The story, the world-building, the power system—it all just hits different. Sadly, XIETIAN passed away before he could finish the story. May He Rest In Piece.
This fanfic is partly my way of keeping that story alive, in my own way and partly me finding this idea fun and interesting.
I'm also a huge fan of Strongest Necromancer of Heaven's Gate by Elyon. Another amazing series, I definitely recommend reading. While reading this novel I suddenly had the idea, what if there was a necromancer in the Blood Warlock world, and so here we are, some of the characters will have the same name and so will some of the skills that's why I wanted to warn people.
So if you're into necromancy, apocalypse settings, badass MCs, harems, and some good ol' chaotic power scaling, you'll probably feel right at home here.
