Chen Tiezhu, who graduated with a major in civil engineering, was challenged by a customer when delivering express delivery. He climbed to the 28th floor to deliver 50 kilograms of dog food. On the way, he received a call from HR: "It is recommended to start as a supervisor, with a monthly salary of 2,800." In desperation, a meteorite hit his tricycle, and the delivery order turned into a system interface: [Send dog food to 210 BC, recipient: Xu Fu].
From then on, he began a fantasy career in which "you can travel through time and space only when you are in a delivery state." He went to the Qin Dynasty to deliver "Eternal World Special Immortal Food" (actually dog food) to Xu Fu, and beat up Zhao Gao by the way; he went to Liangshan to optimize the delivery route, which resulted in Fang La becoming more powerful; he sent the instructions for the tightening curse to Sun Wukong, and found that the sender was actually a six-eared macaque.
As the shuttle goes deeper, he gradually discovers the truth: the future world has been swallowed by the "delivery black hole", and he encounters another self in the ruins - every time the system delivers an order, a parallel world collapses. Finally, he returned to the Qin Dynasty and opened the box at the bottom of Xu Fu's boat. Inside was himself wearing a courier suit, holding the courier note in his hand: [Sender: Chen Tiezhu, Recipient: Chen Tiezhu, Item: Space-Time Station System, Note: Do not open].
