North America After the Apocalypse: My Vehicles Upgrade Without Limits

[Apocalypse + Urban Superpowers + Upgradable Vehicles + No Female Lead + Ensemble Cast + No Angst] He was in North America, and had just bought a used car when the apocalypse hit and zombies came calling. Tao Li floored the gas pedal... Wait, this used car was older than he was, and it could upgrade itself? Navigation: Mileage 100/100 miles. RV mode upgraded automatically. Tao Li: What good is an RV? How am I supposed to survive the apocalypse without weapons! Navigation: Mileage 200/200 miles. Weapon mode unlocked automatically. Tao Li: You can really do that? How about giving me some supplies? Navigation: Mileage 500/500 miles. A supply drop is ready. From Nevada to New York, his vehicle could upgrade as long as he reached the required mileage. Several months later, the members of the North American First Squad of the Apocalypse Safety Committee gazed up at the colossal object passing through the sky: a floating mobile battle platform comparable to an aircraft carrier in the sky. They all exclaimed, “You call that thing a vehicle?” Yu, a black-haired woman with a presence as cold as a blade; Chang Hu, a medical student stranded in North America after being separated from her mentor; the ultimate academic genius Yilai, ranked among the world's top hackers; and... Kevin, whose visa had expired, working illegally at a convenience store and living on instant noodles. The five, all from different walks of life, found themselves together by a stroke of fate, awakened their superpowers, and began writing their own legendary tale in a world overrun by zombies.
