In the afternoon, Duan Yun went very smoothly in the club competition, and he was red all the way and successfully advanced.

After a week of various competitions, Duan Yun has not only adapted to this rhythm of life, but also gradually began to enjoy it.

The last game of the afternoon was Go, facing an opponent whose strength was obviously inferior to his own, Duan Yun was in an unusually relaxed mood, and chatted with the female president of the Go club for most of the day, and drank five cups of tea, and then ended the game with satisfaction.

After dinner, as usual, Duan Yun still came to the library, preparing for evening self-study.

Since the other two boys were eliminated, only Duan Yun and Liu Linna and Yang Ying were training together today.

However, after Duan Yun sat opposite the two of them today, he quickly felt that the atmosphere was a little weird.

After the three of them greeted each other, no one spoke, and Duan Yun continued to tutor his English and Chinese.

Although these two courses are no longer Duan Yun's 'shortcomings', he obviously needs to continue to work hard compared to his math scores.

It's just that when they are immersed in studying, whether it is Yang Ying or Liu Linna, they always look up at themselves from time to time, sometimes for dozens of seconds, and their eyes seem to be thoughtful.

If it was only an occasional thing, Duan Yun could still accept it, but after more times, Duan Yun also began to feel a little inexplicably hairy.

"Is there something wrong?" Finally, when Duan Yun saw Liu Linna's gaze looking at him again, he immediately looked at her and asked with a smile.

"Uh...... That's the case, I have a question I want to ask Duan Yun, I don't know if it's okay?" Liu Linna smiled slightly and said to Duan Yun.

"Of course there's no problem, we're all in a training group, don't you need to be so polite?" Duan Yun nodded and said.

"That's good. Liu Linna bit her lip lightly, and then handed a piece of A4 paper with test questions that had been prepared in front of Duan Yun, and said: "I have never been able to answer these three questions, maybe I am not capable enough, I don't know if Duan Yun can help me take a look." ”

"Well said. After Duan Yun took the exam paper, he was stunned after taking a look.

It turned out that among the three questions given to him by Liu Linna, two of them were almost the same as the last questions of the two CD papers he took yesterday, but the conditional numbers in them were slightly changed.

The last question is more difficult, in Duan Yun's opinion, the difficulty of the last question given to him by Liu Linna is obviously beyond the scope of the first year of high school, and if you want to solve it perfectly, you even need to use some university mathematics knowledge.

"This ......" Duan Yun shook his head with a smile when he saw this, and said, "These three questions are a bit difficult......

"Well, these questions are really difficult, I haven't found a suitable idea after thinking about it all afternoon this afternoon, and it's normal that you can't do it. After Liu Linna finished speaking, a strange color flashed in her eyes, and she was about to withdraw the exam paper from Duan Yun's hand.

At this time, Yang Ying also glanced up at Duan Yun, and a touch of disappointment flashed in her clear eyes.

"Wait!" Seeing this, Duan Yun didn't return the exam paper to Liu Linna, and then said, "Although it's a little difficult, it can still be done!"

In fact, Duan Yun had already seen that Liu Linna was preparing this exam paper for herself, and nine times out of ten she wanted to test herself, although Duan Yun didn't know her purpose for doing this, he didn't want his teammates who would participate in the Olympiad together in the future to despise him.

Then, Duan Yun picked up his carbon pen and quickly started answering his own questions.

For a while, Yang Ying and Liu Linna's eyes focused on the A4 paper at the same time, and their faces showed a dignified look.

"Rustle. ”

This time, Duan Yun did not deliberately streamline the steps of answering the questions, but quickly wrote down the answers that had already appeared in his mind.

Three minutes later, after Duan Yun finished writing this volume, he put the pen in his hand down to the side, and said with a smile to Liu Linna:

"It's done, I just don't know if it's right. ”

"Well, so fast...... Let me see. Seeing this, Liu Linna's face suddenly showed surprise, and then she took the exam paper from Duan Yun's hand.

And Yang Ying was also next to Liu Linna at this time, and their eyes fell on the exam paper at the same time.

At first, the faces of the two were still a little suspicious, but after a few minutes, Yang Ying and Liu Linna's faces showed surprised looks.

"This question is really ingenious...... After reading the last question, Liu Linna shook her head with a complicated expression, then raised her head and smiled and said to Duan Yun: "It seems that I shouldn't doubt you, you are indeed a real genius." ”

"Hehe, thanks for the compliment. Duan Yun smiled, and then said: "I also have outstanding math scores, and other homework is very average, which can be regarded as a serious deviation." ”

"Wait, why haven't I learned this formula for you to solve the last question before?Where did you learn this?" At this time, Yang Ying picked up the exam paper, pointed to the last question and asked Duan Yun with a puzzled expression.

"That's actually a sophomore math Olympiad question, and it's normal that you haven't learned this formula in your first year of high school. Liu Linna explained to Yang Ying, and then said to Duan Yun: "Duan Yun, have you pre-studied the mathematics of the second year of high school in advance. ”

"Hmm. Duan Yun nodded and said, "I don't have much entertainment at night, I like to read math books, and I did read math textbooks in the second year of high school......

Duan Yun naturally wouldn't say that he was a master of mathematics, so in order to avoid Liu Linna and Yang Ying being suspicious, he found the whole reason to prevaricate.

"It seems that I didn't try hard enough. When Liu Linna heard this, her face seemed thoughtful, and then she said to Duan Yun with a sincere face: "Then I hope that Duan Yun can give more advice." ”

"It's easy to say, if you have any questions in the future, just ask me!" Duan Yun seemed to feel that his tone was a little loud in his words, and then added: "Although my level is also a tile, but you two Zhuge Liang plus me, a stinker, it is estimated that we can't solve any problems!"

"Hehe, you're too modest. Liu Linna smiled slightly when she heard this, and then said: "You are the real Zhuge Liang." ”

"He's a big slippery head!" Yang Ying also said with a smile at this time.

Obviously, after this morning's incident, Yang Ying and Liu Linna did suspect that Duan Yun had spent money to bribe Director Qin, although this incident did not prevent the two of them from obtaining places in the competition, but it made them somewhat despise Duan Yun's speculative personality.

And if Duan Yun's level is really not enough, when he participates in the group stage of the National Olympiad in the future, he will also drag down the team and affect the ranking of the group, which is undoubtedly something that Liu Linna is worried about.

But after passing the 'test' just now, most of the two girls' doubts about Duan Yun were immediately dispelled.

"By the way, in order to celebrate the three of us successfully qualifying for the competition today, I plan to invite the two of you to dinner, I don't know if you are willing to go?"
