When weirdness comes to reality, the world is cut into countless "weird realms". Every weird story has an iron law, and anyone who violates it will be killed. Everyone is desperately trying to survive, studying the rules and looking for a way out. Until one day, Chi Yuan, an ordinary person rated F, walked into an S-class ghost story. Instead of following the rules, she whispered to the monster body: "According to the seventh article you made, your behavior just now violated the rules." The ghost story collapsed in front of her. From then on, people were horrified to discover that this girl was not "breaking through" - she was "sentencing" strange stories. When those strange and arrogant beings trembled and asked her who she was, Chi Yuan opened a black book and smiled slightly: "Don't be afraid, I'm just... Someone who specifically finds out your mistakes."
