The celestial hound devours the sun, heralding the apocalypse. A young girl with a heart condition, Xu Zhi, is cruelly abandoned by her parents in a city of death.

Countless aberrations and monsters are born from this city. In order to resist their invasion, humanity has exhausted its efforts, sealing off the city completely and designating it as a Forbidden Zone for the Living.

No one knows that within this city—now a nest of monsters—a girl quietly sits in a wheelchair, playing a mysterious game console that appeared out of nowhere.

Every time she successfully cultivates a powerful follower in the game, the dark mist shrouding the city churns and stirs. The aberrant creatures who kneel before her in the game and call her “Mother” begin to emerge from the fog, one after another, bringing the city under their rule.

By the time the outside world finally prepares to explore this death-filled, perilous city, they remain unaware that a frail girl has already become the God of all monsters in the Forbidden Zone!
