Shen Wei, a delivery boy in Licheng, accidentally inherited a Buddhist amulet and was dragged into the "dark gap", a forbidden area under the city. His new job: within the first seven to forty-nine days of the death, deliver the underworld express with obsessions to the designated living person. If it times out, the Head-Down Plague will break out. Every time he sends an order, he can temporarily change his identity - pretending to be a relative of the deceased, pretending to be a police investigator, or even becoming the person who owes the most to the other party. However, if your identity is revealed, it will trigger an inspection by Heaven, and you will encounter a fatal accident with a small probability. What's even more outrageous is that the more hated he is by living people, the stronger his ability to travel through space becomes. In the beginning, Shen Wei just wanted to save his life by sending cheating orders. Until he broke into the largest Buddhist amulet smuggling network underground in Li City and found that all the hidden cracks pointed to the same manipulator behind the scenes. The recipient on the latest delivery note was actually himself.
