In the apocalyptic ruins, mechanic Lin Ye chases the mysterious black shadow to uncover the connection between his sister's disappearance and forbidden technology.
Three years after the end of the world, the once prosperous city has become a ruin of reinforced concrete. When the wind passes through the broken buildings, it will always bring out the whimper of metal friction. Lin Ye huddled in a studio that was renovated from an abandoned subway station, his hands covered in oil as he tightened the screws of an old generator. In the corner were piles of mechanical parts plucked from the ruins, each piece bearing the mark of the old era. He is a rare mechanic in this ruins. He relies on repairing equipment for scattered survivors in exchange for cans and medicines to support his belief in finding his sister Lin Xi. Before Lin Xi disappeared, he was a researcher in the "Ark Project" genetic laboratory. It was the last hope project of mankind before the end of the world, but now there are only abandoned strongholds scattered around.
