Black rain fell, and the city was cut off from power, water, food, and medicine. Others awakened to the combat profession and relied on their fists to grab resources; but Lu Chenzhou awakened to the ridiculed "Doomsday Logisticsman". In the first order, he sent antipyretic medicine. Later, he delivered water, food, electricity, medical lines, and also the order in which a city could survive. When the black business group strangled the throats of many cities by cutting off supply, they connected logistics stations, storage points, hospitals, power stations, grain depots and intercity service areas into a network. In the apocalypse, what can be delivered is not express delivery, but life.
