Doomsday Fortress Convoy

After half a month of torrential rain, the apocalypse came without warning. An unknown gas erupted from the Antarctic ice, causing plants and animals to mutate. Only ten percent of humanity worldwide remained uninfected. By a stroke of luck, Wei Dayun hijacked a truck on his way to work and fought to survive on the road. Later, he happened to help rescue a military commander's convoy. Wei Dayun declined the military's offer to stay and chose to keep wandering and saving people. The military refitted his truck into a high-tech, double-decker mobile fortress. Along the way, he rescued an auntie, a young girl, and a mature beauty.

The four of them searched for supplies and weapons as they traveled, while also modifying the truck. Using the supplies Wei Dayun found along the way, he prepared a truck for each of the women. Linking the vehicles end to end, they formed a magnificent convoy. The four wandered from place to place, saving people along the way.

The four of them stayed together for twenty years, fending off countless attacks by mutants during that time.
