Hunting Calamities, Yet Becoming the Lord of Calamity?

[Urban high-level martial arts + apocalyptic calamity + dual Systems + devouring evolution + ruthless action + no female lead]

When Yan Yuran woke up, a calamity creature was on top of him, tearing into his abdomen.

The two people who had tied him up as bait were the very ones he had just saved.

They said, 'You're just an ordinary person. It's better for one of us to die than all three.'

Yan Yuran didn't argue.

He simply sent the woman back into the creature's jaws, then dealt with the man hiding in the car with his own hands.

Then two Systems awakened in his mind at the same time.

Kill the wicked and settle their karmic debts to gain karmic power; hunt calamity creatures, collect their essence, seize their abilities, and break through to new realms.

Others hunt calamity creatures to protect the human world.

Yan Yuran hunts them because they make him stronger.

Only when the nine layers of seals began to loosen and the Abyss's countless calamities bowed before him did he realize...

The Lord of Calamity, hunted by humanity for more than two thousand years, might be none other than himself.
