MTL - Harry Potter’s Book of Sin - Chapter 237 "Peak July, Audiovisual Feast"

As a virtuous wife, does it include tolerating his cousin, enduring his concubines, bearing his mother?

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.

“Waking up from sleep, Ye Feng realized that he had transmigrated to a world where the cities had awakened and the whole world lived in symbiotic relations.

Every young person of age would choose a symbiote that was compatible with them.

Some people built a symbiotic relationship with the Ancient Great Dragon of the Origins. After they matured, they could shatter the earth with their dragon breaths.

Some people built a symbiotic relationship with the Twelve Winged Flaming Angel. After they matured, their sacred light shone upon the world.

Some people built a root-level symbiotic relationship with Succubuses. After they matured, they became insanely attractive and charmed the world.

However, Ye Feng’s symbiote was the most unremarkable creature, a Slime?!

Fortunately, he activated the system and awakened the six great sequences at the beginning!

[Perception]: Your ability to sense danger and opportunities is amplified significantly.

[Devour]: You can devour any living being that is smaller than yourself to increase the size of your own body.

[Split]: You can split your body into smaller parts. Each part will retain part of the initial body’s abilities.

[Regenerate]: The recovery capabilities of your various stats are amplified significantly, at the same time your adaptability is increased rapidly as well.

[Mimic]: Your symbiote will evolve at an accelerated pace. Every time it evolves, there is a chance that it can awaken a new ability.

Watch how Ye Feng’s Slime grows to rule the world in the end…
