Gray is the main color of the world. There are tall buildings, alloy ground, vehicles, sky and three huge gray spheres hanging in the sky. A dead metal world. Is this supposed to be a ruin? Walking in the silent steel jungle, Chen Jun can’t help thinking like this. But unlike the ruins in my impression, everything here has no trace of damage. At least from the appearance, there is no trace of damage on the surface of these cold steel. It seems that they are not abandoned because of serious damage, but more like a dormant, sleeping giant beast – this is what I think of more It’s a proper title.
