After a catastrophe known as the "Rust Catastrophe", world civilization fell apart. A microorganism that eats metal and replicates itself turns the steel city into a tomb. The surviving humans huddled in scattered settlements and relied on searching for non-metallic materials to survive.
Scavenger Lingxu has an unusually high resistance to deadly rust dust, and can even vaguely sense its concentration. When his beloved sister Ling Yao contracted a strange disease related to a new type of rust, Ling Xu's world completely collapsed. In order to save his sister, he must break into the dead city that was completely engulfed by rust, "Jingbei City", and look for the legendary bunker No. 734, Which is the only one that may contain the antidote.
In this journey of a narrow escape, you not only have to face mutated monsters spawned by rust, but you also have to be wary of other survivors who have long since lost their humanity and are struggling to survive in the wasteland. Lingxu's innate special ability is not only his sister's only hope for survival, but it may also make him the prey coveted by everyone. How can he find a way out among the ruins and rusty dust of human nature?
