Humans are born with a lifespan of only a hundred years.
This is not the law of nature, but a shackle deliberately placed upon us. An unknown force from antiquity has always suppressed the limits of human growth. A hundred years is the end. Is it a cage or a blessing? No one knows.
In Global Year 3500, a mysterious substance invades Earth without warning. Paranormal events erupt across the world all at once: the slit-mouthed woman knocks on doors in the dead of night in Sakura Country; the Knocking Ghost wanders in endless circles through apartment buildings in Kimchi Country; countless monsters roam the lands of the ancient Eastern nation; and across the ocean, vampires and Satan's followers return to the mortal world, while indescribable beings listen to humanity's cries...
The will of Earth is forced to awaken, opening a twenty-year "newbie period" for all humanity.
Over those twenty years, some go mad, some awaken, and some evolve.
Only after those twenty years will the true apocalypse begin.
But the most despairing thing isn't how terrifying the monsters are. It's an ironclad rule: the paranormal entities cannot be killed.
There is no cultivation and no shortcut. Only evolution can win you a sliver of hope in this collapsing world.
Will you survive, or become a new slave?
(This book features folklore and language systems from different regions, and has a vast worldbuilding scope. The pacing is slow, so enter with care. But once you're drawn in, you'll discover that true terror comes from how little we have ever understood this world.)
