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.

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

But deep down, Roderik did not want to believe it. A single human fighting against a powerful wyvern? Sure, it was possible, but such a feat was typically reserved for well-known adventurers. Damian did not seem the type.

"Why are you spouting all this nonsense? You cannot win against a wyvern, and you cannot win against us! You will die here, and your lady too. All of your belongings will be ours!" Roderik said, cruelty evident in his eyes.

Damian ignored him, turning his head to look at Morgana, who stood beside him. "Do you want me to deal with them alone, or will you assist?"

Morgana placed her hand on her cheek, considering. "Well, I wanted to practice my blood magic, but I still need to master my first attacking spell. You can handle them alone. We could use some of their bodies to practice your necromancy spells."

"Agreed," Damian replied. "Perhaps I can resurrect one of them as a mindless zombie. They are weak, so I might succeed."
