In 2035, a large number of abnormal points appeared in the super first-tier city Hanhai City - they were disguised as ordinary urban scenes (such as abandoned subway stations, old office buildings, and internet celebrity check-in places). When humans trigger specific conditions to speak taboo words, touch certain items, or their emotions reach a threshold, they will be pulled into the abnormal space. Each space corresponds to an urban legend or unfinished event. The rules are strict. If you clear the level, you can obtain the source of essence. If you fail, you will be assimilated into the space and become a background board without independent consciousness. Hidden behind the scenes is the "Reaper" organization. They create artificial anomalies, collect the spiritual energy generated by humans in extreme environments, and attempt to use Hanhai City as a container to awaken the sleeping "Shadow of the City."
