In the Naruto world, Jiang Chen obtained the apprenticeship ten thousand times return system, as long as he taught his apprentices, he could get a correspondingly high return reward.

Everyone: “You call your brother on the lips, but you actually kill him. This girl is too scary!”

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.

An ancient proverb from the Homo sapiens era once stated, “Light and darkness can never be united because they are natural enemies arranged since the creation of the universe.”The statement seems plausible, yet it may contain inaccuracies...——————————————Leon Kruger, a 22-year-old man counted among the three of humanity's heroes, is dispatched by the Holy Empire of Mankind to invade the territory of the Demon Empire—an enduring adversary of humanity for over 7000 years.Wielding the Great Holy Sword Zenith and commanding a legion of thousands of holy troops, he leads the raid on the Desert of Chaos, facing the elite armies of the Demon Race with unwavering valor.Even, he engaged in direct combat against the Demon Emperor, who was actively leading the war on behalf of the Demon Race!Unfortunately, he never foresaw that his offensive was a cunning scheme orchestrated by the Emperor of the Holy Empire.The emperor aimed to eliminate Leon, perceiving him as a threat to his position as the ruler.Furthermore, unbeknownst to him, he had been poisoned before setting out for war, leading to a catastrophic defeat at the hands of the Demon Emperor and resulting in his capture as a prisoner of the Demon Emperor.Envisaging torment at the hands of the notorious Demon Emperor after his capture, he was surprised to find that this foreseen ordeal did not come to pass!The Demon Emperor, unveiled as a remarkably beautiful woman, unexpectedly and without apparent cause, asked him to be responsible for abandoning their triplet daughters?!“Nani!
