A sudden "grey fog" has descended on modern cities, and the world has plunged into an apocalyptic crisis. Human beings may mutate into beasts, or awaken special abilities. Chen Mo, a low-level worker, awakens the "spiritual embodiment" golden finger while on the run, which can transform the concrete images in his mind into physical objects, from daggers, medicines to fortifications, and gradually develops unlimited possibilities of "spiritual creations". He started from surviving in a village in the city, formed a team of survivors, cracked the secret of "consciousness pollution" at the source of the gray fog, and fought against the mysterious organization trying to control the direction of human evolution. Finally, using spiritual power as a bridge, he led the remaining humans to rebuild civilization in the wasteland. The highlight is the application of imagination that manifests the spirit (such as using the drawings in memory to make a generator, using childhood picture books to make a protective shield) and the real game of survival in the apocalypse.
