One day, monsters spawned across the world, gateways to dungeons appeared everywhere, and the blue screens heralded the end of days. The apocalypse. The ruin of the world. Amongst the ruins of the world, they survive: the players, those granted power by the system and led by the 2nd regressor, the King of the Crows. He who mastered the system, learned the truth of the apocalypse, and seized the keys of absolute authority. But even a King cannot stop the fall of mankind.

Earth had been destroyed by Devils, and as a result, the humans who lived there were transported to Paradise, a new world far vaster than their original planet. Dragons flew across the never-ending skies, roaring toward the heavens. Elves grew trees and tended to the flowers. Dwarves crafted armor and weapons to use for battle. Demons started wars for fun. It was chaotic, yet it was still a home. Then, when things were just starting to look up, the cataclysm struck. Only one man could face the imminent disaster, but he still failed in the end.

My name is Killian Dunn. I'm eighteen, a high school senior, a gamer, and, oh yeah, the Harbinger of the Apocalypse. Not exactly what I had in mind as a career path. Reality took a nosedive when Armageddon came knocking. It brought with it classes, levels, and skills, as well as a horde of Lovecraftian abominations to use them on. I never wanted any of this, but the sick god who orchestrated this whole nightmare has my family. Their lives are forfeit if I refuse to play his game. The prize? A wish. With it, I can protect my family, fix everything that's broken, and save the world.

When the cultivators came to Earth, they destroyed our entire civilization in a matter of hours. Armies fell, cities burned, and that was before the moon turned red and filled our world with monsters. Now, over a decade later, what's left of humanity slaves under the heels of our Qi-infused masters. The luckiest of us might even become one of them, they say—if we serve the Dynasty well enough and harness the power of Qi. But I want none of that. I'm sick of serving, and I want nothing to do with their world. Instead, I want them to pay for what they did to mine.
