People have long anticipated the decline of earth's civilization, but no one seems to have imagined that the earth would become like this: towering trees, giant mushrooms with a faint blue light, and the elusive "black mist." No one knows where he comes from, and no one knows where he will go if he is swallowed by it. The only place not invaded by the black fog is occupied by rich and powerful people. It has high-tech equipment and a paradise-like life, but alone... There is no most natural wind. Will God help them return to the beginning? A post-apocalyptic story with two male protagonists, Blue Star x Feng Yue, will the person who has been protecting others in the shelter also be protected? Can androids really understand human emotions? Bionic Man 1, don't enter if you don't like it.
