In a wasteland world where civilization has collapsed, order has become the price of survival. Chen Mo, a former deliveryman, was bound to a mysterious "last mile" delivery system. His mission is to deliver the "hope" they desire most - a box of medicine, a bag of seeds, and a key piece of information to the survivors scattered everywhere. The reward is not money, but random skills beyond common sense, precious materials, or secret fragments that are enough to reverse the doomsday situation. When he thought it was just a cruel trading game, he gradually discovered that every piece of cargo he transported was dragging him toward a huge conspiracy about the origin of the virus and the truth about the world.
