Core driving force: An unthinkable disaster caused by scavenging made the grassroots Zong Linchuan hold the mysterious "express box" and become the most wanted criminal in the wasteland. Various forces (interstellar cleaners, human laboratories, armed scavengers, greedy warlords, mysterious AI) launched a crazy pursuit for him for different purposes. Relying on the wisdom of the market, the garbage he picked up, and a mutated dog that ate expired dog food, Zong Linchuan accidentally cleared away the fog of the doomsday during his desperate runs. Behind every short-term "safety", there are deeper conspiracies and foreshadowings.
