To escape the suddenly appearing monsters and deadly poisonous gas, humanity built underground shelters and numbered them in the order they were completed.
After ten years of recovery, humans discovered that the poisonous fog had cleared from some parts of the surface, and certain areas had once again become suitable for life.
So humanity decided to return to the surface.
The young Yang An earned the top score on the new-recruit test and joined the legendary Vulture Squad of the Seventh Marine Division.
But the squad was attacked during an exploration mission.
In the end, every member except Yang An was killed. The incident also led Yang An to uncover an astonishing secret.
A boy with the ability to transform into beasts, and an ancient book that writes its own stories.
A tangled web of factions, and all kinds of strange beasts roaming the wasteland.
Everything is within The Creed of the Light Chaser.
