My phone rang at midnight.
After the call was connected, there was only silence on the other side. Three seconds later, a line of red words appeared on the wall: "Those who have answered the call need to answer three questions. If you answer incorrectly, the phone line will crawl out of the screen to find you."
I am a graduate student in psychology, and I am best at finding logical flaws in irrational behavior. But I soon discovered that this "midnight phone call realm" was just the tip of the iceberg - there are countless dead spaces called "uncanny realms" in the world, and each space has a set of absolute rules: you can't look in the mirror after midnight, you can't knock on the door for the third time, and you can't be alone for more than ten minutes...
If you break the rules, you will die.
If you follow the rules, you may not survive.
What's even scarier is that I found that I could see the hidden information behind the rules. Thirteen years ago, my parents died in an S-level mysterious realm. The only clue they left pointed to a village that was wiped off the map - Fengmen Village.
Now, the people from the Trick Door have found me. They said: Your parents are not dead. They're waiting for you behind that door.
Then I can only knock on the door.
After all, the rules say it can't be opened. But the rules don't say, you can't knock it.
