Apocalypse: My Shelter Can Be Infinitely Upgraded

When disaster is about to strike, a group of survivors travel to a desolate world and accept the challenge of a survival game. From horrific acid rain to endless natural disasters, the sky is burning while the earth is burning, and radiation is rampant, no one is immune to the dangers of this hellscape. The only way one can survive is to build a shelter and slowly upgrade it in the hope of surviving another day. Fortunately, Su Mo awakens a doomsday survival system that allows him to infinitely upgrade and upgrade his shelter! The main shielding wooden door can be upgraded to a metal door, which in turn can be upgraded to a composite door; the wooden spear can be upgraded to a bronze spear, and finally an electromagnetic spear... While everyone is struggling for survival, Su Mo has returned fully loaded and well-equipped to dominate the post-apocalyptic world. "He had been using the refrigerator while some of us were lighting oil lamps!" "The walls of his shelter alone are dozens of meters thick, making it the safest place on the planet." "Before I die, I hope to spend a day in his sanctuary..." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
