Everyone's Survival in the Wasteland: My Shelter Has Unlimited Entries

When they woke up, tens of billions of people around the world, together with their homes, were transported to the dangerous underground cyber wasteland world! Schools, hospitals, and communities each form underground settlements. The only exit is the "death elevator" leading to the ruins on the surface. While everyone was still fighting for a spot in the elevator, risking their lives to plunder some parts and getting beaten to death, Si Ming discovered that his home had acquired unique characteristics. Others' safety boxes are only one cubic decimeter, while his safety box is the entire house! This house can even be summoned! Not only that, he also awakened the [Shelter Unlimited Entries] system. [Window] + [Analysis entry] = Window of omniscience! Scan everything, and see all supplies, monsters, and enemy weaknesses! [Shelter] + [Teleportation Entry] = Unlimited teleportation! Ignore the elevator and land anywhere on the earth in one second! [Wall] + [Isolation Entry] = Invincible Domain! Radiation, virus, mental pollution? Doesn't exist! While the top players were still fighting for a can of Coke, Si Ming was already lying in the living room with a constant temperature of 26 degrees, eating hot pot and admiring the raging mechanical beasts on the surface through the panoramic floor-to-ceiling windows. "The legs of that eight-claw mecha are pretty good. Take them off and install an automatic walking system for my house."
