"Dude, have you heard the screaming in the dormitory?"
That night, my roommate and I were playing games when a scream suddenly exploded.
The next second, a group message popped up on the phone: "Don't open the door, don't look out the window, don't make a sound."
But under the crack of the door, blood had already flowed in.
Now, the knocking sound of "dong, dong, dong" sounded outside the door, unhurried and slow, each knocking on the apex of people's hearts.
What was even more terrifying was that when they looked out of the peephole, there was no one outside at all.
But the knocking continued.
Only then did we discover that this school hides countless deadly rules——
Want to live! Follow the rules first!
