Apocalypse: My Secondhand Wuling RV Upgrades Without Limit

Other people are frantically stockpiling tens of billions' worth of supplies for the apocalypse? All I have left is a beat-up secondhand Wuling van! From the start, blood rain pours down and zombies surround me. My max-level green-tea ex-girlfriend even tries to shove me into the zombie horde! [Ding! Apocalypse Battle Vehicle Upgrade System successfully bound!] [Beginner's gift: Alloy Armor Module! Basic Power Engine!] I welded the doors shut and slammed the gas pedal to the floor! “Vroom!” The beat-up Wuling instantly transformed into an iron fortress, with its defenses maxed out! Can it automatically collect explosive cores after running over zombies? [Ding! +10 cores. Unlocked: Twin-Barreled Heavy Machine Gun Turret!] [Ding! +50 cores. Interior space tripled, with a built-in temperature-controlled bathtub!] While other survivors were still risking their lives for a mouthful of sour water... I was lounging in a spacious, hundred-square-meter apartment on wheels, drinking ice-cold cola and mowing down the zombie horde! “Want to get in my car? Sorry, the windows are welded shut!”
