Su Yuan, a master of folklore, was rejected for his thesis and has no chance to find a job.
When he was desperate, he received a strange interview notice - a unit under the Civil Affairs Bureau, a professional counterpart, a monthly salary of 8,000, including food and accommodation. The interview only asked one question: "Do you think the disaster relief ceremony is useful?" He passed it in a daze.
After joining the company, he discovered that he was not joining a "social and cultural research department" but a secret unit that specializes in dealing with "abnormal incidents."
The first task: Investigate a strange rumor about rules in an elevator. Every night from 11 o'clock to 1 o'clock in the morning, that elevator will change into another appearance. Five rules are posted on the mirror - don't press the buttons, don't look in the mirror, don't answer what's whispered in your ear, leave immediately wherever you stop, and never look back.
A programmer broke the rules and is now lying in a psychiatric ward with only one sentence left in his mouth: "There is someone in the mirror."
Su Yuan found a clue based on an unpopular symbol written in his graduation thesis.
And the thing in the mirror also discovered him.
At 11 o'clock that night, he walked into the elevator. What he doesn't know is that there are more "abnormalities" waiting for him in the city. And the paper that was killed was exactly about how to solve them.
