Doomsday Disaster, My Semi Can Be Upgraded

A meteor shower brought an extraterrestrial virus. Humans and animals have become mindless monsters... The dead bodies also caused the same changes in insects... Tide-like zombies, mutated mosquitoes and flies all over the sky, primitive animals and plants crawling out of the ground, and mysterious portals that sometimes appear and sometimes disappear... When people want to look up to the sky and sigh, they see the burning flesh and blood spaceship breaking through the atmosphere... It seems as if the real natural disaster has just begun. Humanity picked up the wasteland technology that had been honed for several years, only to find an aerial fortress made of steel rushing out... The man driving it was named Su Yang. Before the end, he was just a semi-trailer driver. Fortunately, the system was bound to his car, and as long as the vehicle moved, he could get 1 survival point every second. Buy any system equipment you want! Ion cannons, Gauss rifles, drone swarms, mechanical exoskeleton armor, intelligent driving... While others were staying at home waiting for rescue due to the fog, he had almost destroyed the city. Su Yang grabbed the handle of the vehicle-mounted MI34 Vulcan minigun, and the red flames spit out thousands of projectiles per second, sweeping across the zombie swarm: "Yes, that's what it feels like, absolute firepower coverage."
