As soon as Qin Dong's words fell, no one dared to squeak.

Duan Yun also sat back in his place.

"Alright, take your exam papers and answer the questions carefully. Qin Dong looked at the plum blossom mechanical watch on his wrist and said, "Give you an hour, hand in the paper first and answer all the questions correctly to win!"

As soon as Qin Dong's words fell, the five people in the Olympiad group quickly took the carbon pen in their hands and officially began to answer the questionnaire.

For a while, the eyes of more than a dozen math teachers in the entire conference room were staring at these five students.

This is definitely the strictest invigilation exam since the establishment of Yinghao Middle School, plus the principal Qin Dong and the director of academic affairs Qi Pengfei, it is basically three or four people staring at a student, even the candidates of the college entrance examination definitely do not have this treatment!

At this time, Qin Dong and Qi Pengfei's eyes were all fixed on Duan Yun's body, especially Qi Pengfei, who looked at Duan Yun with a bit of anxiety and worry in his eyes.

Although it sounds a little ridiculous, there is no doubt that at this moment, Qi Pengfei's reputation and future prospects are completely dependent on Duan Yun's exam results, once Duan Yun fails the exam, he will basically be convicted of 'taking bribes to help students cheat', even if he can stay in school, this stigma may not be completely cleared for a long time!

So compared to Duan Yun in the exam, he was more nervous and anxious.

At this time, Duan Yun was not in a hurry to write the answer, but picked up the exam paper and carefully reviewed the question from beginning to end.

Seeing that Duan Yun was still unhurried and unhurried, Qi Pengfei's face became more and more gloomy.

As for the principal Qin Dong, he was just sitting upright in his chair at the moment, his eyes narrowed slightly, his face was calm, and he seemed to be leisurely raising his spirits.

"All students should hurry up. After a full three minutes passed, seeing that Duan Yun still hadn't started writing, Qi Pengfei, who was sitting diagonally opposite, was obviously a little uncontrollable, and reminded him.

"Uh. After Duan Yun heard this, he answered softly without raising his head, and then spread the exam paper on the table and picked up the carbon pen.

At the same time, except for Duan Yun, the other four people in the Olympiad group have all answered the first question, and it is obvious that the difficulty of this paper is not high, and it should be that a few of them can answer it.

However, Duan Yun suddenly frowned at this time, his eyes staring at the last question of this exam paper, and his brows squeezed into a Sichuan character.

Because in his opinion, this exam paper is not too challenging, and the difficulty is basically the same level as the B paper he took before, except for the last self-choice question, which is a little troublesome.

In fact, this last question can also be solved, but the process of solving the problem is very cumbersome, and if you list all the steps, it will take at least more than 20 steps!

It can be said that this is the most cumbersome problem solving step that Duan Yun has been exposed to so far, and it is even more cumbersome than the final question he got in the city's Olympiad before!

It's hard to imagine that more than 10 years ago, there would be such a difficult test in the Olympiad exam paper, and even now, it is definitely not easy for the best students to solve this question completely!

Considering the importance of today's exam, Duan Yun did not challenge to simplify the steps of this question, but decided to solve all the steps on scratch paper.

And just when Duan Yun was about to write the answer to the last question on scratch paper, the other four people in the Olympiad group had basically all answered the second question, and Liu Linna was even about to finish the third question!

You must know that there are only twelve questions in this exam paper, and in less than ten minutes now, Liu Linna has almost finished answering a quarter of the exam questions, and such a high efficiency is really staggering.

After seeing this scene, the math teachers present focused their eyes on Liu Linna's exam papers, and their faces showed surprised eyes.

Although the other two boys were not as fast as Liu Linna, they were about to finish the second question, and when they looked up and saw Duan Yun, who was sitting opposite, had just started to write, their eyes showed a look of pride.

As for Qi Pengfei, after seeing that Duan Yun had just put pen to paper on scratch paper, he was already disappointed.

"Rustle~" The atmosphere in the conference room was extremely solemn at this moment, only the sound of the tip of the pen rubbing against the paper.

And Liu Linna became the protagonist of this exam without any suspense, when the other people except Duan Yun were just about to solve the third question, she had already solved the fifth question, and she instantly distanced herself from the others.

Yang Ying's answering speed was not slow, her expression was quite focused, and she did not let Liu Linna open up too much gap with her.

Only Duan Yun is still just writing and drawing on scratch paper, and he has not finished answering a single question on the exam paper!

Seeing this scene, the math teachers present all peeked at Qi Pengfei, who was slumped in the chair at this time, with a little sympathy in their eyes, although the exam had only lasted for more than 20 minutes, but the current situation was clear at a glance, Duan Yun, who had not finished answering the previous questions on the exam paper, was obviously at the bottom, and as other students answered more and more questions, Duan Yun's chances of 'turning the tables' were getting slimmer and slimmer!

However, Qin Dong, who had been squinting at this time, glanced at Duan Yun, and then sat up straight, his expression revealing a little surprise.

Then, Qin Dong simply stood up and walked behind Duan Yun, when he saw Duan Yun's dense answer steps written on the scratch paper, his expression was stunned at first, and then his eyes became more and more solemn!

The clock is still ticking.

At this point, the exam had been going on for nearly forty minutes.

Forty minutes is not a short time for an ordinary exam, but it is obviously not enough for a standard Olympiad exam.

International math Olympiads are generally more than six hours long, and although the difficulty of this exam paper has been reduced, it is still too urgent.

Liu Linna has already solved the ninth question at this time! There are only three questions left before they are all completed!

When Liu Linna wrote the answer to the ninth question, the teachers who had been paying attention to her answer all the time let out a soft exclamation in unison!

There is no comparison and there is no advantage or disadvantage, among the other people, Yang Ying is solving the eighth question, while the other two boys have not finished writing the sixth question!

"Jingle bell!" At this time, a sharp bell came to mind in the school building, which was the sound of the end of the first class in the morning, that is, the exam had been going on for a full forty-five minutes!

"Smack!" When Duan Yun finished writing the last step on the draft, he finally breathed a sigh of relief, threw the carbon pen in his hand on the table, and pressed his temples with his two thumbs to soothe his nerves a little.

And the principal Qin Dong, who had been standing behind him just now, also slowly walked away from him at this time, and a flash of surprise flashed in his eyes......
