Rule Horror: I Can See the Wrong Answers

On the eve of the college entrance exam, their homeroom teacher, who had been missing for three days, suddenly sent seven rules to the class group chat. 【Do not look at the proctor's face.】 【Do not write your real name on the answer sheet.】 【If the announcement calls your name, tear up your exam paper immediately.】 【There are only thirty examinees in this room. If you count a thirty-first person, pretend you didn't see them.】 The whole class thought it was a prank. Until the next day, a classmate who had gone missing really did take a seat in Exam Room Seven. Everyone was searching for the right answers. Only Shen Xu could see the red words seeping through beneath the exam paper: 【Wrong answer: Write your real name.】 【Anyone who believes a wrong answer will die.】 But Shen Xu later discovered that he could see the wrong answers not because he had been favored. It was because, from the very beginning, he had been holding the red pen that would grade this exam. And this college entrance exam was only the first question. The whole class thought it was a prank. Only Shen Xu could see another line of bloody writing beneath the rules: 【One of the seven rules is a wrong answer.】 【Anyone who believes a wrong answer will die.】
