Legendary FBI Detective - Chapter 21 - : Men in Black

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!

That night, the delicate purple-eyed woman in a wedding dress sat on their bed as her husband observed her with a grin.

“So,” he drawled, his voice wicked and magnetic, “I can't see my wife's face even on my wedding night?”

“My lord has promised to fulfill my one wish,” the woman commented, securing the veil that covered the lower half of her face with slightly trembling hands.

He stared into her mysterious rare purple eyes. “May I ask, why such a wish?”

She stared back at him. “My lord might not like to see ugly things.”

He smirked and stepped towards her. “I never had a liking towards pretty things.”

------

Seren, the infamous daughter of the witch, and Drayce, the ruthless and vicious son of the Devil.

No one had ever seen her face as the witches are meant to be ugly, but he was the one who never searched for beauty.

She was cursed to never fall in love, but he wished to be the only man she would ever love.

A cursed princess married off to the Devil's son to destroy his kingdom but the Devil's son had a different plan for her.

The secret of her birth will be revealed only to lead the way to unleash the hidden powers inside her which no one can control.

With the hidden dangers desiring her power, can Drayce and Seren protect one another or will the darkness swallow them whole?

A strange event happened in Blue Star, a large number of Blue Star people were affected by a mysterious force, and their souls temporarily traveled to another world.

It’s a dark, weird world

Not only are the prices extremely high, but there are also many evil spirits quietly appearing. At the same time, various forces are fighting each other, and the people of the lower classes are suffering.

Yang Fangben, the attending physician of the mental hospital, also traveled through a strange incident.

Fortunately, he found that he had awakened a proficiency panel.

As long as you keep refreshing your proficiency, you can improve your own realm.

He grew up secretly, with corpses piled up under his feet, and he unknowingly embarked on a path of sagehood.
