Summons eyeball familiars to spy on him at school. Wears his dad’s shirts like she owns the place (because she kinda does). And worst of all? She’s disturbingly good at playing the “loving stepmom” role… with a wink that says she knows exactly what she’s doing.Caught between sanity, seduction, and spontaneous hellfire, Kazuki must survive:• A stepmother who flirts like a villainess with a mission• A house full of demonic chaos• And the terrifying possibility that he’s starting to like it⸻A romantic comedy harem full of magic, mischief, misunderstandings—and one very dangerous MILF.If you like seductive demon queens, chaotic slice-of-life, and nonstop supernatural comedy, this is your next obsession.

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.

“Yin Fu Jing” has a saying: It is also a stealth machine, and no one in the world can see it or know it.

Xu Hong travels through another world and finds that there is an extra volume of “Longevity Picture” in his mind.

Relying on this, not only can you monitor your own and other people’s lives in real time, but you can also steal secrets to convert abilities and lifespans.

The picture of longevity, the picture of longevity.

Therefore, Xu Hong set a small goal…to live 100 million years.
