This is an underground barracks space designed in industrial style, built with heavy military green metal materials. One side of the wall is exposed rock structure, and a large number of exposed pipes are arranged on the top and walls. Bunk beds, storage racks and military storage boxes are set on both sides of the space, and electric control panels and explosion-proof sealed doors with electric hazard warning signs are installed on the walls. Cool white ceiling lights are matched with warm yellow wall lights, and the overall atmosphere is tough and cold, with the characteristics of a military base or doomsday shelter.
