Lone Wolf in the End of the World: My RV Upgrade System

The end of the world is coming, and zombies are rampant. Ling Fan, an orphan who was just betrayed by his girlfriend, started with a dilapidated RV that was about to fall apart. In desperation, the [Doomsday RV Upgrade System] was forcibly bound successfully. It's just that this system is a bit venomous. At the beginning, his car was rated as a "mobile coffin", and the novice gift package was actually a rusty ax and a few toothless biscuits? But surviving is the instinct engraved in the bones of the orphan Ling Fan! Kill zombies, pick up trash, complete tasks, and earn energy! "Upgrade the tires! Upgrade the defense! Install the machine gun tower for me!" "Water purifiers, small vegetable gardens, medical beds... The quality of life in this post-apocalyptic world cannot be lost!" "What? Can you modify anti-gravity and energy shields? Let's do it!" From rusty old cars to doomsday mobile fortresses armed to the teeth. From the cute guy who gets weak at the sight of zombies, to the feared lone wolf boss. Ling Fan drove his steel home, upgrading and racing all the way through this collapsing world!
