Zhou Dachuan, who has been driving long-distance for more than ten years, has eight months of salary delayed by his boss Sun Wanjin, and his mother's medicine is about to be cut off. On the day he goes to claim his unpaid wages, he only gets a truckload of unsellable rotten sweet potatoes in return, but accidentally drives through a thick fog and arrives at Heishi City, where grain routes are completely cut off. A truck driver whom no one in modern society thinks much of becomes a lifesaver in ancient times: swapping sweet potatoes for gold, coal to save a freezing city, a truck to transport military rations, and a semi-trailer to block a gorge. From an old truck to a cross-border transport fleet, Zhou Dachuan relies neither on martial arts nor on power, but on the true skills honed from over a decade of driving. He will make his wage-defaulting boss bow his head, and even more so, use a modern logistics line to support four cities.
