In the year 2077, the "iron fog" that lasted for a hundred years finally swallowed up the last dome city. The survivors foraged in the rusted steel forest, the tomes of the Old World were used as kindling, and the skeletons of idealists became the nests of rats. Chen Mo, a scavenger who makes a living by dismantling abandoned robots, unearthed half of a well-preserved female prosthetic body from a landslide. The holographic chip embedded in its chest was playing the same image three times per second: under the blue sky and white clouds, a group of children were running on the grass, and a female voice in the background murmured "We should have a tomorrow." This scene, which was incompatible with the reality shrouded in iron mist, was like a rusty nail wedged into his already numb heart. When people from all walks of life came to compete for this prosthetic body - a religious sect that massacred dissidents in the name of "purification", a black market businessman who made a fortune by selling human organs, and a mysterious organization that claimed to have the truth about Iron Mist - Chen Mo had to take this pile of cold parts and find a way to stand again in the ruins of humanity. This is not a story about saving the world, it's just a group of people struggling in the mud, trying to recognize the reflection of the human beings they once were in each other's eyes.
