Post-Apocalyptic North America: My Vehicle Can Be Upgraded Infinitely

[The end of the world is coming + urban superpowers + vehicle upgrades + no heroine + group portraits + full text without swords] I was in North America. I had just bought a second-hand car when the apocalypse came. Zombies were coming. Tao Li stepped on the accelerator... Huh? This second-hand car that is older than him can automatically upgrade? Navigation Tips: When the mileage reaches 100/100 miles, the RV mode will be automatically upgraded. Tao Li: RVs are useless. How can we survive in the last days without weapons? Navigation Tips: With mileage of 200/200 miles, weapon mode is automatically unlocked. Tao Li: Really? How about some supplies? Navigation tip: Mileage 500/500 miles, airdrop supplies are in place. From Nevada to New York, vehicles can be upgraded as long as the mileage reaches the standard. A few months later, everyone in the first team of the Apocalypse Security Committee in North America looked up at the behemoth flying in the sky, a floating mobile combat platform comparable to an aerospace mothership. Everyone said in unison: "You call this thing a vehicle?" Yu, a black-haired woman with an aura as cold as a knife, Chang Hu, a medical student who is separated from her mentor and stranded in North America, Eli, the ultimate academic master on the world's hacker rankings, and... Kevin, whose visa has expired and is working in a convenience store and eating instant noodles. Five people with different identities came together by chance, awakened their powers, and wrote their own legendary story in this apocalyptic world where zombies are breaking out.
