Harry Potter: Ero World - Chapter 132: The Core Expansion Ritual! Part-1 ~Heavy NSFW~

On a dark and windy night, the legendary military hero Qin Yu found a stunningly beautiful and drunk CEO. From then on, Qin Yu's life was completely transformed...

The day dungeons appeared on Earth, everything changed! From ordinary beasts to monstrous ones, attacks were common throughout the globe, and no one was safe.

After countless studies using these beasts as subjects, Humankind developed a serum capable of awakening incredible abilities in humans, leveling the battlefield.

With the serum came heroes and villains, those who wished to use their powers for good or bad.

The Garmony Upper School was a place for the elite with the sole purpose of creating heroes to fight the villains and explore more of the dungeons after the beast attacks increased for no apparent reason.

Damian Romero, a youth who received the serum after turning 18, yet got no unique ability. It was not uncommon for one to not receive power, but it was still a blow to one's pride.

He went rogue after the news, drinking alcohol and having a good time with women, and it was at that moment, when he was putting his toy to play, he got a surprise.

[All-in-One System Unlocked]

Damian's unique ability was a system with multiple functionalities, but after he studied it, it seemed this system worked with a different type of coin called Erotic Coins!

Improve his body? Buy any item or unique ability from his system's store? All Damian needed was Erotic Coins, and he knew how to earn them!

Vampire Slave Number 43, or the self-named, Azriel Ruinous, learned about the history between the humans and the Vampires and it filled him with rage and hatred.

Nonetheless, he was helpless to do anything.

After years and years of suppression, the Vampires have become the weakest race in the world.

However, lady luck seemed to be on his side as Azriel found an ancient jar filled with mysterious blood that will not only change his, but his race's destiny as well.

This, will be the story about the rise of the self-named, Azriel Ruinous, and the Return of the Forgotten Blood Empire.

...

“Have you heard about the rumour?”

“What rumour?”

“They say that there's a Vampire on the loose, he's out there killing humans mercilessly”

“Hahahaha! That's the funniest joke I ever heard! Vampires? Those Slaves? Hahaha!”

“Yeah, I feel the same! I think someone just started this rumour as a joke! Hahaha! How can those weaklings kill us, humans?”

“True True…”

In a bar, two middle-aged men talked and laughed as they discussed the recent rumour they heard.

Seeing those two, a drunk old man shook his head as he sighed.

“Ignorance is bliss indeed…”

“These younglings do not know what the real fear is…

The vampires may have fallen… but my old bones still remember the days when they were in their prime…”

The old man sobered up in an instant and his body shuddered in fear as the memories of the long-forgotten horror appeared in his mind.

He then took a deep breath as he patted his trembling body and muttered.

“I just hope that they are not back…”
