My disciple, whom I raised and cherished with my whole heart…That same disciple has returned and is trying to kill me.“Before you fall, before you cease to be my idol, my hero, my sun, I will kill you with my own hands. For your honor!”Just wait for a while…I’ll bring you back to your senses.

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.

Chen Rui, an otaku from earth, is reborn into a human body in another world, who falls into the legendary evil, brutal world of the devil called Mozu where humans are treated as food. He has to survive while facing horrors of the devil, violent dragons and a variety of powerful enemies by depending on a strange super system chip and his wits. Surrounded by Devil’s beauties such as black-bellied lolita princess, cold queens, violent dragons, charming poisonous devils …

Wanting to live in the Devil’s world is hard! Wanting to live in the Devil’s world as a human is harder! Wanting a human to be the devil’s son-in-law is hardest!

Let us see how a small otaku uses power and strategy step by step starting from an ordinary human to writing a legend as the devil’s greatest son-in-law.

It was in the middle of the night that the woman who would be the Duchess came to see me.

She said my father and mother died, and my kind uncle became king.

She said it’s not worth it for me, the crown prince, to be living in hiding, too.

“A while ago, Your Highness had been hiding from me. With all due respect, is that for the sake of survival? Just because your parents died doesn’t mean you have no reason to survive. Actually, that fact alone made it all the more reason why you should live. If you die now…”

If I died now?

When I asked her while looking at her eyes, the woman eventually brought out the harsh truth with empathetic eyes.

“It’s like a dog’s death.”

“That’s rude….”

It’s been a long time since I said that. In a short while, he has been treated as a madman and beaten to death just by saying similar things. She loosened her arms that held me and I suddenly stiffened up due to it. Because I thought she might have loosened her arm to hit me. But she didn’t.

She knelt down with one knee in front of me, just like a knight.

“Hastred’s Sarian raised her salutations. May you accept it gladly.”

My first knight is beautiful and kind.

“Are you on my side?”

“Yes, Your Highness.”

It was all a lie.
