Unemployed young man Chen Ye mistakenly touches the ancestral compass and suddenly sees monsters wandering in the neon lights of the city - "data gluttons" eating mobile phone signals on subway platforms, and "reflective spiders" climbing on the glass walls of office buildings. He started a late-night live broadcast of "Monster Catching Record", and when he used the golden light of the compass to seal the monster, the screen barrage suddenly exploded: "Is the female ghost in red behind the anchor a special effect?" When his partner Lin Wei debugged the equipment, he discovered that the "demon crystal" rewarded in the live broadcast room could actually materialize. Every time the top brother "Xuandu Guanzhu" rewarded Chen Ye, a mysterious man in a Taoist robe chased Chen Ye. When they solved the mystery of the "Phantom Taxi" during the live broadcast, the compass suddenly projected a map of the city from a hundred years ago. Under the old alleys covered by high-rise buildings, there were "Internet Demon Mothers" fed by live broadcast traffic. When Chen Ye pointed his cell phone at the monster, he was shocked to realize: this live broadcast of monster hunting watched by the whole people has long been a hunting ground for the monster world to select "spiritual medium sacrifices".
