I Build a Shelter in the Wasteland

Gu Ze traveled to a post-apocalyptic wasteland world, where infectious agents, radiation, and various natural disasters were ravaging the entire world. The original person was persecuted by his enemies and forced to wander in the wilderness. Gu Ze, who traveled through time, brought the souvenir "Wasteland Lord Panel" and built a shelter of his own by building various buildings. "City Wall Lv.1: Made of 1m thick concrete, capable of withstanding blasting impact equivalent to 4 to 6 kilograms of TNT." "Watch Tower Lv.1: Obtain "True Sight Lv.1" Within 50m range" "Ammunition Factory Level 1: Able to produce bullets of most calibers" "Medical Manufacturing Laboratory Level 1: Able to manufacture simple medicines" … When the disaster intensifies and civilization is on the verge of collapse, a city that seems to come from the future rises from the ground Gu Ze said: "It's time to bring some technological shock to these infected bodies."
