Notice: This story contains R18+ themes, including violence, sensual and sexual content, blood-related addiction, and dark psychological elements. Reader discretion advised.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.

Ever since Su Tian had transmigrated, she received a “Villain Bosses Mentoring System” that could automatically identify villainous bosses IN THE MAKING.

As for her missions, they were a little more complicated. For example:

Stopping the boy in her class from deviating onto the path of becoming a villain;

Turn the boy who was going to create a global financial crisis into Jack Ma of the new world;

Talk the strange girl working at the toy shop out of her spending habit, because she will be the cause of hyperinflation!

And the boy from the countryside that she ran into, please give up on developing bioweapons! Why don’t you focus on the Nobel Prize instead?

Just when Su Tian thought all the little villains were growing straight up into upstanding people under her “education of love”, the small villains brought about a big villain…

The young man has slender arms and legs and he cornered her into the restroom. He looked deeply into her eyes said, “I also need …”

Su Tian shuddered, “What… what do you need?”

“The education of love,” said the young man meaningfully!

Ten minute later, Su Tian… was educated.

System: This system is only responsible for identifying villains IN THE WORK. Matured villain are outside of its parameters.

Soul Piercing Konoha, born as a civilian, will go to the battlefield of the Third Ninja World War tomorrow.

Just graduated from “Ninja School”, Yangtai, who only knows three body techniques and a D-level hemostasis technique, looked at the full of energy, and finally made up his mind – “The battlefield is too dangerous, I’d better go to other worlds to hide. !”

- Description from novelbuddy

While others transmigrate into the role of a villainous young lady, I, on the other hand, became the ab*sed female lead in a sadistic novel! I’m trembling with anger, but there’s no one to seek justice from! This is a story about a girl who transmigrates into a weak, pitiful, and helpless heroine. With her natural charm, gentle demeanor, and a touch of tea-loving personality, she conquers the hearts of the villainous female leads, ultimately achieving a sweet and satisfying counterattack.
