Blue Heart's will is about to collapse, and all the young adults in the world are thrown into the wilderness by a mysterious force.
Civilization collapsed, technology became obsolete, and humans became prey here.
Savages and monsters are rampant, and there are even terrifying beasts possessed by dark consciousness, testing the verge of death at every step.
Either fight your way out in blood and fire and find the opportunity to reach the sky;
Either sink in despair and eventually become the nourishment of this land.
This is a survival game with no retreat and the ultimate gamble on redemption.
New people, new books, brothers.
