In novels related to the apocalypse, there were plots that involved the infinite upgrade of the fallout shelter under the global catastrophe. For example, in some novels, when the protagonist faced global disasters such as meteorite falls, radiation surges, ice ages, terrifying rat disasters, infinite typhoons, extreme high temperatures, volcanic eruptions, etc., he would activate the fallout shelter system, gradually upgrading the fallout shelter from a rock fallout shelter to a steel fallout shelter, a tungsten fallout shelter, a vibranium fallout shelter, etc. At the same time, the internal facilities such as defensive weapons,(Machine gun turrets were gradually upgraded to heavy artillery blockhouses, light prism fortresses, etc.), manufacturing equipment (cold weapon manufacturing tables were upgraded to gun work tables, heavy artillery manufacturing rooms, mecha manufacturing halls, etc.), and transportation tools (large touring cars were upgraded to armed touring cars, heavy tanks, hyperspace vehicles, etc.) were also constantly upgraded. There were also novels where the protagonist traveled to a world facing the end of the world (the explosion of the sun, the arrival of a huge meteorite, etc.), activated the fallout shelter system to create an underground city and make it infinitely upgraded, such as the upgrade of the door (iron door to alloy door to laser tunnel, etc.), defensive weapons (crossbow to small caliber machine gun to large caliber machine gun to Thunderstorm machine gun to machine gun, etc.), protective equipment (radiation protection suit to exoskeleton armor to mechanical armor to small mecha to giant mecha, etc.). This setting was commonly seen in doomsday survival novels. Click on the link below to read the comic "The System Sent Me a Sanctuary"
