The Great Cataclysm Hit, but I Survive by Running a Food Cart

In a single night, the whole world is transformed. A mysterious black fog blankets both poles, and an unknown contaminant causes plants and animals to mutate on a massive scale. Seeing no way to deal with the disaster, the Alliance government gives up. It announces that it will stop providing public services everywhere except the First-Class Zones, and diverts what little energy remains back to the Capital Zone. Civilians? They're on their own. We welcome people with special abilities to join the Alliance Defense Force. Ordinary people are advised to make their own way to a survival base. If you haven't turned into a puddle of muck after being contaminated, congratulations: you may have awakened a new ability. Lin Xia: Too late. I'm already contaminated. The good news: he didn't turn into a puddle of muck. The bad news: his superpower is a mobile food cart! Lin Xia (scratching his head): Fine. It can be upgraded, and with a few repairs, I can use it as a camper van. Who could've guessed that the food cart would have side effects too! Torrential rain, thunderstorms, icy fog, extreme cold, and spore storms come one after another. He has to stockpile supplies, fend off mutated creatures, and get teleported to another dimension to sell late-night snacks. The diners at the Black Fog Farm cackle viciously: "Bad review, bad review! Give us a bad review and we get to eat the vendor!" Neon signs go dark one by one, and vendors are dragged out of their food carts to become the diners' next meal. It's a feast for the otherworldly creatures! Only Lin Xia manages to hold on. Every time he successfully opens for business, his food cart's features are upgraded. Waterproofing, insulation, temperature control, stealth. In the age of the great cataclysm, could a food cart really become a shelter?! But his companions are starting to act strangely... Chi Zheng: I'm not changing. I just can't keep pretending anymore. It's that time of year... I... I want to take Xia Xia back to my nest... and keep him there... @&$---@$*# Beep (censored) Theme: Stay steady and advance one step at a time
