Weird rules invade reality, randomly blocking a convenience store, a hospital, and a school. People who break the rules disappear quietly. Chen Mo, a 24-year-old night shift clerk, was involved in the regulatory realm of the "Happy Community Convenience Store" early one morning. He has no resources, no background, and no experience in clearing levels. He only has a line of red text that occasionally pops up in front of his eyes: [You open this door, and "it" will grab you by the back of your neck in three seconds. Others relied on luck and trial and error, while he climbed forward by relying on repeated death reminders. Later, someone asked him the secret to clearing the level, and he said: "I just beat death by three seconds every time."
