Ten years ago, a sudden cataclysm caused more than 500 million people around the world to vanish!
Some dropped dead where they stood in the street!
Some mysteriously disappeared in broad daylight!
Some spontaneously combusted without warning, turning to ash!
Some became dried corpses before everyone's eyes!
Some elderly people grew younger, passing through middle age, youth, adolescence, infancy, the embryonic stage, and finally vanishing as fertilized eggs!
And some babies rapidly grew in their mothers' arms within minutes, becoming adolescents, then young adults, middle-aged, and elderly, before finally turning into withered bones!
Ten years later, the truth gradually came to light!
Those who died during the cataclysm became spirits with miraculous powers, wandering the world.
They could seize human bodies and resurrect by taking their place, or be absorbed by humans and become a source of their power.
In a world where humans coexist with extraordinary undead beings, the true cause of the cataclysm and an apocalypse-level crisis are gradually coming to light!
