Seth Evergreen was the greatest scientist of his time. With his insatiable hunger for knowledge and groundbreaking discoveries, he had made Earth reach new heights of prosperity and scientific advancements.

But everything changed when he stumbled upon the life equation, cracking it and discovering the fabled 'healing factor.'

Seth believed he had found the key to eternal youth and announced his discovery to the world in the form of a new drug. But then the mutations began. The human body, it seemed, was not meant to be perfect.

The drug's effects began to spiral out of control, creating monsters out of those who had taken it. After spending 7 years trying to remedy his mistake, he finally gave up and pulled the trigger.

But when he opened his eyes again, he found himself in a world unlike anything he had ever seen before. The world of Gilea, where magic and mana exist, and the strong prey on the weak.

Determined to complete what he had failed to do in his last life, Seth, now known as Silas Skylark, sets out to become the strongest mage, to take Gilea out of the dark ages and into an age of prosperity and change.

Unbeknownst to him, the life equation branded itself into his soul, morphing his body and mind into a being with only one goal...

To evolve!

But as the shadow of his past looms over him and powerful forces seek to control him, Silas must overcome weaknesses and reach new heights.

Will he succeed in his quest to bring prosperity and change to this world, or will his past sins come back to haunt him once again?

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 world had changed when the System arrived, alongside the Cataclysm that filled the world with monsters. The technology was gone, replaced by classes and skills that allowed the people to fight back. When Devon ended up as a Blacksmith, a class that didn’t grant Intelligence, he had to face the reality, that his old career that he loved - mathematical sociologist - was over. Instead, he had ended up as yet another discarded member of the production class, overshadowed by the existence of the System Shops to the point of total marginalization. But, what if all he needed was to reapply his scientific thinking to the System...
