Reborn as a Vampire in a Dying World: Undeath with a System

Notice: Contains mature and r18 themes



I died in a library, crushed under centuries of forgotten knowledge. Fitting.

Now I’ve woken up in a coffin, starving, undead, and very much not human.



They call me a Fledgling—a bottom-feeder vampire barely above a ghoul. I’m weak, hunted, and tethered to a world straight out of a cursed tabletop campaign. It’s a classic fantasy realm—elves, knights, guilds, and dungeons—but twisted by a dark, rotting magic. The moon shines red, the gods are silent, and every town smells like fear.



To make matters worse, I’ve been bound to a LitRPG system called the Blood Codex.



Level up by draining blood.



Unlock skills by embracing your monstrous nature.



Resist Corruption... or don’t.



There's no prophecy. No chosen one nonsense. No noble title. Just fangs, rot, and whatever I can steal, trick, or kill to survive.



But the deeper I sink into this world’s underbelly, the more I realize something is watching me through the system. The rules are breaking. Dungeon bosses are going mad. Entire towns are disappearing.



And I think I’m supposed to fix it… or maybe finish the job.
