Ordinary young man Xia Bo is unexpectedly swept into the death game "Highway Survival." From the start, all he gets is a wrecked car and a wooden club. Amid extreme heat and scarce resources, he awakens the [Infinite Resource Upgrade System], which can multiply the quality and quantity of basic supplies. By searching hidden supply crates along the highway, he obtains water, food, and fuel, and discovers that killing grassland monsters can make equipment drop. Thanks to a combat skill book and attribute points awarded for his first kill, Xia Bo enhances his physical abilities and unlocks fighting techniques, gradually adapting to the perilous rules of survival. As night approaches, he realizes he must use the System to stockpile resources and upgrade his vehicle, searching for a way to survive in a highway world overrun by monsters.
