The National Goddess Reborn - Chapter 221 - Reversal  

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!

Power comes with a cost... and it was something she was willing to trade her soul for.A few nights before her wedding, Lauren sought a way to break her fourth engagement. Known for her bad reputation as the rebel princess, she was the only lady who had the guts to step foot on the Everston mansion, the house of a notorious warlord, in the middle of the night.She offered him a wicked alliance that the entire kingdom did not see coming: a marriage.A vixen pretending to be a damsel in distress and a man whose crimson eyes screaming for bloodshed. Could something blossom in this treacherous dance of lies and deception?--“Are you upset?”She eyed him sharply. “Should I be honored that I got tricked by you, milord?”He drank the remaining wine in his glass with one gulp and put it on the wooden table.He stepped in front of her. His hand was on the rail on her side while his other hand grabbed her glass and finished her wine before putting it down.The way his Adam's apple moved with his every violent gulp made her feel a tickling heat around her nape.When he brought his attention back to her, he licked his lips to wipe off the trace of wine.“How shall I make it up to you then?” he asked with his deep voice, like a seductive devil asking his victim how she would like to be killed. Dangerous yet… enthralling.
