After the High School Entrance Examination, I Made Rules at Elite College

Beichen College never explains the rules. The world is dark and yellow, there are four classes. You will know where you are on the first day of school, that's all. The last one in the yellow class, ten people leave every semester, no exceptions. Everyone's first reaction when they got the envelope was to go up. Lu Tingbai glanced at it and put it back in his pocket. He has only one purpose here - Find the designer of this system.
