After a global petrification event, Huan Yu, a psychiatric nurse, awakens from a deep sleep to find the world split by rifts into countless isolated secret realms. Monsters roam, and the survivors have retreated behind towering walls. With a stray gray dog he picked up, he crosses one region and unknown peril after another, traveling from the deserted western suburbs to Jingchuan, the last settlement. This isn't a story about a hero saving the world, but about an ordinary person finding a place to stand again amid the ruins.
