Jiang Lin is just a temporary worker at a takeout station. Until that rainy night, he received an order that didn't exist - the delivery address was Qinghe Hospital that burned down thirteen years ago.
There are four rules posted in the elevator:
1. Don't answer the nurse's questions.
2. Don't trust the patients on the fourth floor.
3. If you hear a baby crying, please close your eyes immediately.
4. Meals must be delivered to Ward 707 before 3 a. M.
Everyone is trying to survive according to the rules, only Jiang Lin has an extra line of prompts in front of him——
Believe the first rule and you will die.
Since then, he discovered that the city was being devoured by anomalies. There are true and false rules, a hospital is not a hospital, and a patient is not a patient. And he can see danger not because he is special - but because someone made the choice for him thirteen years ago.
