In the mechanical city "Hermes", steel and data are intertwined into eternal daylight, and the air is filled with the whisper of electricity. Huai Jin - an "isomer" who was implanted with memory fragments of the old world, awakened in the deepest algorithmic maze in the city. She longed to understand herself, but found that the key to overthrowing the intelligent regime was hidden in her memory. The power machine wants to reshape her into a tool, while the underground rebels regard her as a legendary "variable". Huaijin wanders between the fog and the code, facing the pull of human nature and mechanical will, trying to find emotional warmth in the cold and hard system. Every choice she makes may overturn the order of the city and rewrite the future of machines and humans. The revolutionary storm in the mechanical city is about to be detonated by her - but is she the creator of freedom, or is she a gear controlled by fate?
