This is an imaginary fantasy city. Chen Mo, a retired scout, applied to become the security guard of "the first high-end community in Luteng City". On his first day on the job, the captain handed him a copy of the "Security Code": 1. Do not open the door to a woman wearing red after three o'clock in the morning. 2. If you hear a child singing in the underground garage, please play "Unity is Strength" immediately. 3. No matter how strange the owner looks, keep smiling and checking their access card. When others screamed for their lives during the strange incident, Chen Mo just knocked on the guard box glass expressionlessly: "Comrade, please show your ID, health code, itinerary code and the history of strange contacts in the last fourteen days."
