[NO NTR]

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!

The MC will not start as a villain, but something will shift his mind in the future.

All-in-One System: All I Need is Erotic Coins

For a giant, it was a chalice, but for Damian? It looked like a red ocean! He used his Telekineses to stay above the water, and as he looked at it, it seemed infinite.

The feeling of being an ant compared to that filled him, but the constant pain of his broken limbs helped his mind focus on the task in hand: unlock his bloodline.

"My ancestor said I should bath on this…"

Damian was uncertain if that would work, but it was not as if he had any other options. It had to be done. Also, the feeling of having that demon near him made him uneasy, so all Damian wanted was to get over with that and leave that place.

"Let's do it, Damian. How bad can it be?"

He kept using his Telekineses, moving his body inside the blood. With his legs broken, Damian wouldn't be able to swim, so his ability maintained his safety.
