"Poof, so you want to cheat......" Yang Ying laughed when she heard this.

Yang Ying's voice was a little louder, and the other students in the same examination room looked at the two of them, and the beautiful woman from Yinghao High School sitting by the window also glanced at Duan Yun and Yang Ying with beautiful eyes, and a touch of disdain flashed on her face.

"Be a little ......" Duan Yun squeezed his eyes at Yang Ying, and then said: "Actually, I really learned too much mathematics, and I will be teased by a few of my buddies if I take a single-digit test, if you can let me copy to a passing grade this time, please eat!"

"Giggles, you're pretty honest. Yang Ying chuckled twice, and then replied very dryly: "Deal!"

"Hehe, that's it. After Duan Yun finished speaking, he found his place and sat down, and put the stationery box he was carrying in his trouser pocket on the table.

At this time, there were more and more people entering the fifth examination room, and after almost everyone sat down, they shifted their eyes to the girl in Yinghao High School, and there were several students who knew each other, and even pointed at the girl and talked about each other.

A few minutes later, the teacher in charge of the invigilator walked into the classroom, holding a stack of thick exam papers in his hand, and everyone took their eyes back from the short-haired beauty.

With a whistle in the corridor, the Olympiad exam officially began, and the teacher in charge of the invigilator briefly explained the discipline of the examination room, and then sent the exam papers.

The moment almost all the students who participated in the competition saw the exam papers, the confidence on their faces disappeared instantly, and the whole classroom became dead silent, and no sound could be heard.

Olympiad mathematics has a certain effect on the mental exercise of teenagers, and can exercise thinking and logic through Olympiad mathematics, which does not only play a role in mathematics for students, but is usually more esoteric than ordinary mathematics.

Therefore, even if the participants are the top students of various schools, the Olympiad questions will definitely not be easy, and even in this kind of exam, it is normal for a large number of top students to not even touch the passing line!

However, for Duan Yun, who has mastered mathematics, this kind of competition is still not much challenging.

After briefly reading the test papers, Duan Yun took out a carbon pen and wrote his name neatly.

After all, there is a bonus for this city's middle school Olympiad competition, and Duan Yun naturally has to treat it strictly.

Duan Yun's pen tip quickly crossed the exam paper, and he wrote the numbers and formulas as neatly as possible to avoid unnecessary deductions.

The previous questions were all done smoothly, and when the others were still meditating and thinking about it, and half of the paper was not finished, Duan Yun had already finished answering three exam papers in a row, and only the last question remained.

The last question of this Olympiad test paper was an additional question, and when Duan Yun looked at my question carefully, his brows suddenly furrowed.

"This question...... It should be beyond the scope of high school students' questions. Although Duan Yun quickly had the idea of solving this question in his mind, he was still surprised that this Olympiad would have such a difficult test question.

Judging from Duan Yun's master-level math mastery comprehension, this additional question obviously should not appear on the exam papers of the high school math olympiad competition, and some of the mathematical knowledge involved in it cannot be accessed until college, and even this question is still extremely difficult for ordinary college students!

"Interesting!"

At this time, the corners of Duan Yun's mouth hooked a curvature, and he took out a piece of white paper for calculation from the bottom of the exam paper, and began to list the formulas on it.

After more than ten minutes, Duan Yun used two full blank sheets of paper to completely answer the entire question, and after he checked it carefully, he would breathe a sigh of relief.

Looking up and looking around, Duan Yun found that the other candidates around him were all lost in thought, and some of them hadn't even finished writing the first paper.

And when Duan Yun saw Yang Ying sitting in front of him, the corners of his mouth couldn't help but hook up a touch.

It turned out that at this time, Yang Ying really deliberately pushed part of the exam papers she had answered to the direction where Duan Yun was, obviously not forgetting to take care of Duan Yun.

"This girl is quite righteous. Duan Yun couldn't help but pouted and chuckled.

Duan Yun said to Yang Ying before that he wanted to copy the paper, but he actually wanted to compare the answer with her, but when Duan Yun found that this exam paper was far simpler than he imagined, he naturally forgot about Yang Ying for the time being.

In fact, this exam paper is said to be simple, but in fact...... The last question is still a bit difficult.

Suddenly, a thought flashed through Duan Yun's mind, so he beckoned to the invigilator and asked for a few pieces of scratch paper for the calculation.

There should be a more optimized solution to this last problem!

Duan Yun picked up the pen again and listed the equation on it.

For the first time, Duan Yun used thirteen steps to solve this question.

The second time, Duan Yun used eleven steps.

The third time, nine times!

In the end, when Duan Yun simplified this question to six steps, it seemed that his mental power was too concentrated and his brain was overused, so that his eyes began to become slightly blurry.

However, Duan Yun still insisted on writing the optimal steps and answers to the last additional question neatly, and then he fell to the desk groggily.

After a while, there was a sudden sound of snoring in the originally silent Olympiad examination room, followed by laughter.

Even the beautiful woman from Yinghao High School who was sitting in front of the window couldn't help but shake her head after glancing at Duan Yun in the 'sleeping', with a somewhat contemptuous look on her face.

In the end, Duan Yun was woken up by Yang Ying with his fingers, and then he handed in the exam paper in a daze.

"You're amazing, it's the first time I've seen someone fall asleep in the exam room. After Duan Yun walked out of the examination room, Yang Ying, who was following him, covered his mouth and giggled and said to him.

"That's because you just met me, and if you had known me earlier, you would have seen it a long time ago. Duan Yun pursed his lips and replied.

"But my plan to rub the rice has failed, I guess you didn't copy it just now, right?"

"Okay, no matter how many points you score this time, I owe you a meal, so it's okay. Duan Yun spread his hands, and then said: "But first of all, I am very poor, and I can't afford to go to high-end places." ”

Duan Yun is actually not worried about not having money to invite guests to dinner now, after all, there is a prize money in this Olympiad competition, and he is still very confident in winning the ranking.

"That's pretty much it. When Yang Ying heard this, she chuckled twice, and then said, "But don't worry, I'm not a picky eater." ”

Duan Yun glanced at Yang Ying, who was smiling, and frowned slightly.

It was the first time he had met such an active and enthusiastic girl, it seemed that she was born with a talent of 'self-familiarity', and she was just chatting a few words just now, but now, this girl has successfully let herself pay for a meal out of her pocket.
