The world has been eroded by a catastrophe called "ashification", and life and matter are slowly turning into dead dust. The last survivors of mankind huddle in a giant city called "Ark", relying on a mysterious energy core to survive. Gu Chuanze, a low-level maintenance worker, accidentally broke into a forgotten restricted area and discovered a top-secret data from a "heretical" scientist. The data reveals that the "ashing" may not be unsolvable, and the rulers of the Ark are covering up a truth that can subvert everything. In order to survive and uncover the mystery, Gu Chuanze was forced to cooperate with black market technical experts and a guard with dissatisfied aspirations. In the cold steel jungle of Ark, he evaded the pursuit of law enforcement and walked step by step towards the center of the storm that could determine the fate of mankind.
