The story takes place in the modern bustling city "Binjiang City", which looks like any first-tier city, with tall buildings and busy traffic. However, under the cover of night and urban legends, an ancient "Yin Division" system is gradually losing control of the Yin and Yang realms for unknown reasons, resulting in loosening of rules, stranded souls, and the breeding of spirits. The "Yin Yang Takeaway System" accidentally bound to the protagonist Zhou Mo is one of the "backdoor programs" left over from ancient times to repair the gap between the two worlds and maintain basic order. This system settles the cause and effect by delivering takeaways containing "yin virtue" or "yang energy" to specific underworld customers (such as ghosts, ghosts, and special dead souls). The rewards can be life extension, minor magical powers, or real currency. This may seem like simple errand work, but in fact every step is walking on the edge of the rules of life and death.
