Chen Mo is a former police academy student who just wants to deliver express delivery safely. His biggest worries are traffic jams and overtime complaints. Until he discovered that his neighbor Professor Wang had been missing for many days, and the milk bottles piled up at the door became a silent alarm. I wanted to give him a simple reminder, but instead I was treated as a pervert by my neighbor Lin Xiao, a lively but bold illustrator. In desperation, he could only carry out investigations on his own, relying on the observation skills honed in the police academy and the courier's unique understanding of the city.
