Thinking of this, the corners of Junxin's mouth turned up slightly, although he didn't look at these questions very much, but he hadn't been exposed to these slightly difficult test questions for so long, although it was still very low-level and easy for himself. However, it also seems to awaken the desire to solve difficult problems that has been dormant in Jun's faith.

For Junxin, in fact, the content of the whole university is not attractive to him, he has done things directly from Jiaotong University to Princeton in his previous life, whether it is a top university at home or abroad, he has stayed in a top university, and the university is actually a process for himself, and he really does not have much hope for what kind of knowledge he can learn.

Among the two top universities in China, Mizuki University and Peking University also have differences in the construction of school spirit, and the simplest one is that the style of Mizuki University is more conservative than that of Peking University. The management of students here is relatively stricter. This is also the reason why Mizuki University is more inclined to build a university as a red engineer after the adjustment of faculties. However, this has led to a conservative and strict academic style at Mizuki University.

Junxin does not want to be subject to such strict discipline, but also because of the influence of the liberal academic style of Princeton University abroad, it naturally feels uncomfortable with such an atmosphere, so it is naturally unlikely to let go of being able to do things according to his own ideas at a certain time. So after scanning the entire test paper, he focused all his attention on the question, while calculating, while filling in the answers quickly, not even interested in making a draft, completely relying on the ability of mental arithmetic, in less than five minutes, the fourteen fill-in-the-blank questions have been completed.

The next questions are all specific calculation questions, Junxin just glanced at it casually, and completely memorized the requirements of the question stem. This is also a special ability that he has after being reborn - unforgettable.

There is no pause at all, and soon inequalities, functions, and differential equations pour out in the pen. The process of proof was also completed little by little, and in less than two minutes, the first big question was completed. This is followed by the second and third questions......

After completing all the twenty questions of the previous official exam content, Junxin casually glanced at the old wall clock hanging on the wall, and the time had just passed twenty minutes.

Junxin, who casually withdrew his eyes and rubbed his sour right hand, completely unaware of his special behavior, seemed to have attracted the attention of some people in the classroom.

Sitting behind Junxin, is a slightly chubby round-faced boy (in fact, all the mathematics department is boys), is the first person to notice Junxin's speed of doing problems, the boy's name is Wei Donglai, Wei Donglai's family is a very rich kind of petty bourgeois family, in China for ten years ****, the whole family is abroad, but after the **** ends, the Wei family is also the first to return to China, and even Wei Donglai, who originally went to school abroad, also returned to China with his father.

However, Wei Donglai studied abroad when he was a child, and because he has a strong talent in mathematics, he chose the mathematics department, but Wei Donglai felt a chill in his heart after seeing Junxin's speed of doing problems.

At first, I thought that Junxin, who was sitting in front of him, was putting on a show, which is a very common and common thing in foreign schools. But immediately Wei Donglai reacted, this is in Mizuki University, China at this time, or candidates from all over the country use a test paper, and can enter Mizuki University through the college entrance examination, how can there be such a showman. Then the rest of the answer is obvious, and the person in front of you must be very familiar with these questions.

"Did he read the test papers in advance, or was he just a math genius?" In Wei Donglai's mind, there is no concept of rebirth at all, so he naturally can't think of the reason why Junxin would do these topics.

And another person who noticed Junxin's speed in doing questions was naturally the invigilator who stood on the podium and patrolled the aisle from time to time. In fact, when Junxin flipped the test paper, the invigilator had already noticed Junxin, but compared with Wei Donglai's suspicion, the invigilator was even more surprised that in such a short examination time, there were freshmen who could do these test questions that far exceeded the level of freshmen almost without thinking.

Because the test questions only come out, they are basically temporary, and the invigilator himself is a question maker, so he naturally knows the inside story of the questions, so he knows the difficulty of these questions, and he also knows the confidentiality and freshness of these test questions. After seeing Junxin's problem-solving speed, I couldn't believe my eyes.

The teachers and professors of Mizuki University are as rigorous and serious as the school spirit of Mizuki University. Therefore, the invigilator's estimation of this test paper will naturally not be wrong. After seeing the speed of Junxin's answer, the only thought in the invigilator's mind was: "It seems that there is a genius among the freshmen this time!" ”

Junxin didn't know what the two people in the examination room were thinking, and he was looking at the two additional questions at this time. Speaking of additional questions, this is also a major feature of Chinese education in this era. Because exams take care of students from all walks of life, they often lead to a lack of distinction. Therefore, for some advanced regions, additional questions will be used to maximize the differentiation of the test. Because of the requirement of discrimination, the additional questions are often very difficult.

The first question of the additional question is the knowledge of number theory, which is the most widely known in China, and the famous Goldbach conjecture is a classic conjecture in number theory, and no one has been able to completely solve this conjecture even in the future. However, the knowledge of number theory in the test paper is obviously not so profound, just the calculation and proof of number theory involved in some simple advanced mathematics. Therefore, Junxin has quickly completed the proof in this regard.

The key is that in the second question, the second additional question involves the knowledge of high-dimensional topology, but it is not so much the knowledge of high-dimensional topology as the manifold is more accurate.

Speaking of manifolds, many people may not understand what this is, but for a simple example, the circumference is the simplest manifold, and some of the more familiar manifolds such as Möbius strips, Klein bottles, etc. are some embodied manifolds. And the title of this additional question is actually the proof of a theorem of high-dimensional manifolds.

Junxin couldn't help but shake his head and smile bitterly, not that he couldn't do it himself, but he felt that such a question might be difficult to figure out for most high school students who had just entered college. But if you can't even understand the question, is there any need to answer it?

"Forget it, I've done it anyway, so it doesn't matter if I'm done with the rest of the questions!" Junxin decided not to think about these problems anymore, but settled down and began to concentrate on solving this "problem".

Although the problem was a little more difficult, it was still completely unchallenging for Junxin, and at best it only allowed him to review the content of topology in advanced mathematics. As a PhD in the mathematics department of Princeton University, and a genius PhD, it is really not difficult to study high-dimensional topology at the undergraduate level. It was still less than five minutes, and the problem was solved.

Then Junxin didn't care how shocking his performance was, and got up and handed in the papers. At this time, Wei Donglai, the invigilator, and even all the candidates in the class glanced at the clock on the wall, and the time had just passed thirty minutes.
