The End of the World: My Shelter Can Be Infinitely Upgraded

[Apocalypse + Rebirth + Refuge + Decisive Killing + Never the Virgin] The red moon has arrived, and the world has become a slaughterhouse of flesh and blood. In his previous life, Lin Rui kindly took in his girlfriend and neighbors, but they used them as bait to push into the zombie swarm, and ended up being eaten alive. When he opened his eyes again, Lin Rui returned to 72 hours before the apocalypse broke out! Awaken the [Dimension Shelter System] and create an absolutely safe Kingdom of Steel! When humans around the world were wailing in despair in the extreme cold and the tide of corpses, exchanging their children for food, Lin Rui was sitting in a constant-temperature shelter, eating hot pot and singing. "In this life, I will no longer save all sentient beings." "I only want to be the only sword holder in this wasteland!" Those Madonnas and thugs who attempt moral kidnapping, breaking and looting? Sorry, I only accept corpses outside my shelter, not any!
