Lin Chufeng, a retired underground boxer, turned to be a courier due to an injury. He relied on his strong force and observation skills to solve strange and dangerous orders such as severed fingers in refrigerators, fraudulent recovery, and stolen documents during the express delivery process. Every order was solved with the obsession of "must be delivered", and he gradually became a "hard-core responsibility" in the express delivery industry. At the same time, he exposed the criminal group behind it and gained the love of metaphysics master Su Muxue.
