Ringing ring~~ The teaching assistant's mobile phone rang, Lu Qiujian frowned and raised his head, it was a very angry thing to be interrupted when she was thinking! Since she is working in the university, she shouldn't know this, why don't she even turn off her mobile phone when she invigilates the exam?

The teaching assistant didn't have an apologetic expression at all, picked up the phone and shook it at Lu Qiujian, "I'm sorry, it's time for the exam, I'm afraid I'm going to take away your test papers!"

"Can't you wait any longer, I've just found the idea for a third question from Professor Thurston's method of geometry!", Lu Qiujian exclaimed irritably.

"Sorry!", the teaching assistant was indifferent, "this is not homework, since it is stipulated that these questions must be completed within two hours, then there are only two hours, now please stand up and put the paper down!"

This kind of student teaching assistant who is still trying to procrastinate at the end of the exam has seen a lot, so naturally she will not give Lu Qiujian a chance, she decisively got up and walked in front of Lu Qiujian, and slowly but firmly pulled the test paper and answer sheet over.

She glanced at Lu Qiujian's answer sheet, there were about two and a half pages of answer sheets full of various mathematical symbols, but unfortunately, these were only the process of solving a question, and he had not completely completed it.

The teaching assistant shrugged, "Ah Ou, it seems that you are in trouble, seven questions, two hours, but you only solved half of them." ”

"If you don't have any of the math students, even if you find a person in the whole of Princeton who can complete any of these seven problems in two hours, I'll give you a million dollars!", Lu Qiujian said angrily, he vaguely remembered that several problems he had seen many times in various magazines and professional books before, and it seemed that Professor Nan had specially collected these problems this time to make him succumb.

"It's a shame that Princeton forbids staff to participate in any gambling activities, otherwise I'd really like to find someone to try!", the teaching assistant took Lu Qiujian's words as a vent for his emotions to lose control after being hit.

"Isn't it worth quitting for a million dollars?", Lu Qiujian said angrily, "How much is your annual salary at Princeton? This is at least your salary income for more than ten years, why don't you try?"

"It's a pity that my work ethic doesn't allow me to do this!", the teaching assistant slowly sorted out the test papers and answer sheets and put them in the file bag, "Now you can go back, I will send you an email to notify you when the results are out!"

"I will also protest to the school about Professor Nan's deliberate difficulty for students!", if it is only beyond the difficulty of the exam questions of his classmates, Lu Qiujian can still accept it, but he believes that even Professor Nan can't solve this kind of question, "I believe that Principal Shirley Tillman will not sit idly by!"

Shirley Tillman, a world-renowned molecular biologist who has participated in the development of the blueprint for human genetic engineering in the United States, participated in the world's first mammalian gene cloning experiment, has worked at Princeton for 15 years, and only became the 19th president of this Ivy League school last year.

President Tillman is known for his passion for creating opportunities for young scientists, and he must have known that Lu Qiujian would not fail to interfere with the injustices he suffered.

"It's your right!", the teaching assistant replied in formulaic language, "But now, I'm going to hand over your exam paper to Professor Nan, you can leave!"

Lu Qiujian snorted and left the office, thinking about the next countermeasures while walking towards the dormitory, if Professor Nan wants to use these problems to sharpen his sharpness a little, then it's okay, he can't deal with it by saying some soft words, presumably he won't take this exam seriously, right?

If you really want to use this exam as the basis for your grades in this course, then you will definitely hang up this course, not only will you waste time to retake it, but you will not be able to continue to participate in the NCAA competition, which is unacceptable to Lu Qiujian no matter what!

If that's the case, I'm afraid I have to go to Professor Wiles, or even President Tillman, to administer justice for myself, but if I get to that point, I will completely tear my face with Professor Nan, and no matter what the result is, one of him and Professor Nan will definitely leave Princeton with an indisputable reputation.

I hope things don't come to this point, Lu Qiujian also felt very puzzled, judging from his usual contact, Professor Nan has no other problems except for being extremely strict with his own study because he is also Chinese?

Anyway, let's wait for the news? In terms of time, he will probably be able to see his test paper tonight, and send an email tomorrow to ask him to make a decision.

Just when Lu Qiujian was entangled, Professor Nan also said goodbye to Dyson and Witten, returned to the office building of the Department of Mathematics, and just walked to the door of his office, the teaching assistant greeted him, "Hello Professor Nan, this is Lu Qiujian's test paper!"

"Oh, let me guess first, how long did it take him to finish the test????

Well, it took him two hours to finish a single question, and he only finished half of the question until the end of the exam. The teaching assistant looked at Professor Nan a little strangely, how could your own students, your own test questions, have such a big misunderstanding of the students' abilities?

"What? I didn't do a single question for two hours?" Professor Nan's face suddenly fell, this is simply impossible! Judging from his usual homework, this student's level has far surpassed that of his classmates, and although the questions he came up with are a little more difficult, they are not like this!

Could it be that his usual homework is done by others, but where can I find a student in the whole class who can reach the same level? Professor Nan frowned and opened the file bag.

I want to take a good look at what you have written, if I find out that you are cheating in your usual homework, Professor Nan picked up Lu Qiujian's answer sheet without looking at the test questions.

When Professor Nan saw Lu Qiujian's problem-solving process, he found that something seemed to be wrong, and he glanced at the teaching assistant with a strange expression, and then looked at Lu Qiujian's problem-solving process carefully.

There is a shift at nine o'clock.
