Zhou Wen, a social worker who is so cautious that he has to read ten negative reviews before ordering takeout, accidentally downloaded a mysterious APP called "Yin De Tong". From then on, he delivered express delivery during the day, caught ghosts and paid off debts at night, and relied on system tasks to survive in the supernatural world. The villains are a group of stupid thieves who think they are smart but are actually stupid. They always want to steal his golden finger but fail time and time again. From being chased by ghosts to having ghosts line up to pay protection fees, Zhou Wen used iron-blooded skills and cold humor to make a comeback in the world of Yin and Yang, starting an entrepreneurial story that is both laughable and mysterious.
