Changle was about to cry: "No, I don't want to fail the exam! Master, please give me one more point to pass. I don't want to be without strawberry ice cream for a month!" Li Er: "Changle, why are you so careless? You may get one more point if you check it more. Okay, don't be discouraged, prepare well for the make-up exam." Han Yue: "Li Er, you have the nerve to say that Changle, someone who got 33 points in the exam, do you still have the nerve to be the emperor of the Tang Dynasty?" Li Er was shocked: "Cough cough cough... Holy Master, this is impossible, why do I get such a low score!" Han Yue: "Look for yourself. There are mistakes everywhere. You have even forgotten the basic theorem of calculus. There are so many big questions that are blank. Have you forgotten that I said that writing a solution is better than leaving a blank? If you are interested, I will give you one point if I am in a good mood!" Li Er burst into tears: "Holy Master,... This novel and its characters are purely fictitious.
