- Description from Novelupdates

A world where the [Demon King] was defeated by a [Hero] that came from another world. People carelessly forgot about their fear of the [Demon King] and of monsters, living in peace.

In a forgotten and run-down cave in the mountains, a new monster that should not have been born was given birth.

The monster’s name was the [Black Ooze]. It was nothing exceptional other than its black color, an ordinary slime.

However, this slime had the special characteristic of being able to take the abilities of the living things it swallowed. It preyed on an insect that had paralytic poison, as well as other animals. Following that, it attacked a human, obtaining his knowledge and [Desire].

Before long, the monster established its target as the female mage that came to explore the cave.

This world still wasn’t aware.

Born without a mana circle into one of the most powerful family of hunters in the country, Luthra was the ultimate failure. Deemed trash and disowned, he was cast out with nothing but the clothes on his back and a cold, self-hating resolve.For five years, he trained his body to its breaking point, only to discover his weakness was a lie. His power wasn't absent—it was a paradox. A 'Negative' mana circle so volatile it had to be sealed by a god at his birth, lest it annihilate his very soul.Now, the seal is cracking. To prevent catastrophe and seize his own destiny, Luthra is given a key: The Negative Leveling System. In this world, power means leveling up. For Luthra, true strength is found by leveling down.Armed with a simple industrial chain and an unshakable pragmatism, he begins his hunt. Every monster core he absorbs pushes him deeper into negative levels, unlocking twisted skills and an incomprehensible strength the world has never seen.They called him a zero. But in a system where Level -10 is stronger than Level 1, Luthra is about to show them what true power looks like from the bottom.

Once all people received Souls and incredible powers. Some were lucky enough to obtain the Soul of an ancient and powerful creature, but fate was not favorable to all.

The world began to change, and creatures evolved. But, it was not the beginning of a new era. It was the end. A couple of months later, a dark mist appeared and destroyed the world. It was a dictate of destiny from which no one could escape.

Wain Norheim was the world's best assassin and the only one who didn't get a soul. However, he was destined to gain the power to confront fate.

Escaping through a portal into another world, he unknowingly began the apocalypse. Even the world failed to expel him.
