Logistics manager Chen Xiao was hit by a truck and plunged into the troubled times of the late Qin Dynasty, and was forced to bind the "Tianji System" - a devilish platform that can purchase modern supplies online but forcefully promotes KPIs. The first task: to deliver antibiotics to Xiang Liang to save his life. When he used drones to help Xiang Yu win the Battle of Julu and used big data to predict Liu Bang's escape route, he thought he had grasped the logistics chain that would rewrite history. The blood-stained jade jue was thrown into Chen Xiao's hand, and Xiang Yu tore up the express delivery form and laughed: "This is a human head, and it will be delivered by myself!" Chen Xiao returned to modern times and found a negative review engraved on the bamboo slips of Chu Tomb: "The deliveryman's attitude is acceptable, but the boss refused to sign." In the museum glass cabinet, the blood-stained jade jue suddenly vibrated, reflecting the face of a young delivery boy with double eyes.
