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.

A 30-year-old NEET is reincarnated into the body of an otaku that choked to death on instant noodles. As he comes to grips with his new life, he realizes that this world is subtly different from Earth. The denizens of this world are far better looking, and this new world also possesses futuristic technology as well as mysterious Yin Yang masters!

After reincarnating, he realized that he was endowed with a miraculous game-like system, which enables him to increase his own stats and transcend the limits of the human body. This system even has a game-breaking ability to save and load in real life!

In this new world that’s akin to a 2-D game, he just wants to enjoy life and head for a glorious future… However, he is quickly embroiled in a complex plot. Can he unlock his true potential and utilize his system to break the shackles that confine him and discover the truth about his previous body’s circumstances?

- Description from novelupdates

my name is Vexsus but you can just call me Vex

I was a human previously like all Isekai protaganists except this time i was reborn as a monster. Join me in my adventures as i discover and explore not only my new body but also this new world i'm thrust into.

I remember the story of a novel I had read in my previous life just before my marriage. If you don’t mess up the wedding, you’ll be poisoned by your husband! So I kissed the pastor who was in charge of the ceremony.

“Commander, are you alright?” shouted one of the holy knights as he approached the pastor who was kissed.

Huh, what?

Wait … are you the commander of the Holy Knights?

****

Rurutia, who was about to die, wanted to spend her last moment in a temple where she felt at ease the most. She started a business with her friends for the temple, and it was a big hit.

“Miss, you have the world in the palm of your hands!”

“Are you a God who has descended to Earth?”

In the midst of being embarrassed by the large crown, the commander of the holy knights himself was also acting strange.

“All I wish for is to be your husband,” he said, his eyes shining with obsession. “Take responsibility for stealing my first kiss.”

This is all so wrong.

It seems that I changed my future.
