The three of them walked around the department store for a while before they finished buying things and left, this one in and one out, Wu Guixiang used some of the money he carried, and a lot of various cloth tickets and industrial tickets.

Li Xiulian looked at the things in her hand, and suddenly felt a little guilty, "Mother, did we buy a little too much?" ”

If the second daughter-in-law is watching here, she may have to explode again.

"Not much." Wu Guixiang said indifferently, "If you buy it, you can buy it, don't think so much, you can earn it again when the money is gone." ”

"That's right, auntie, it's all for the good of the child, it's nothing expensive." Su Qingyun also said.

Li Xiulian was a little determined in her heart, although she said that she was buying things for the small family in the army, she was also afraid that it would be too much and cause the rest of the family to be dissatisfied.

"Milk, auntie, then you go to the eldest brother, I'll go to the library to find the teacher." Su Qingyun said.

Wu Guixiang nodded, "Okay, I'll see you at the station later." ”

"Uh-huh."

Su Qingyun walked to the county library alone, since she was busy with the seeder, she hadn't been to the county to find Chu Xianming for a long time, and she smiled when she saw her coming to Chu Xianming.

"Is it all done?" He asked.

"Hmm." Su Qingyun smiled and nodded, "I have to thank you for the inspiration you gave me, teacher." ”

"I just said casually, you have your own ideas, the teacher believes in you, and you will definitely have a good result in the finals."

"Thank you, teacher."

Chu Xianming took out the simple textbook he had compiled and opened it, "I haven't come to study for so long, let me see if your level has regressed?" ”

"Feel free to check." Su Qingyun's tone was confident.

Although she didn't attend classes for a while, she didn't abandon it, and she was still studying when she was at home.

"So confident?" Chu Xianming smiled.

"Of course you have to be confident as your student." Su Qingyun smiled slyly.

"Not bad."

Chu Xianming began to ask questions, Su Qingyun answered fluently, the teacher and student went back and forth, full of tacit understanding, and before he knew it, time passed minute by minute, and the smile on Chu Xianming's face became more and more obvious and satisfied.

"Very good, it seems that I am indeed learning." Chu Xianming is very satisfied, learning must not only have talent, but also have attitude, this student of his, has both, so she will inevitably go far in the future.

Thinking of this, Chu Xianming's eyes moved.

"Your Senior Brother Chen has written to me." Chu Xianming said.

"Really?" Su Qingyun's eyes widened, a little surprised, in the past, the teacher told her that those of his students felt ashamed of his teaching, and they had not heard from him in the past few years, and they didn't even dare to write a letter.

But now, Chen Zheyu's letter to the teacher shows that he has let go of the knot in his heart and dares to face himself.

"Your brother said that he recently joined a mathematics talent group, will conduct some academic research in the field of mathematics, and will not be in the school soon." Chu Xianming's tone was relieved, "He finally found what he wanted to do." ”

For this student, he can also rest assured.

"Math Talent Group?" Su Qingyun was a little curious.

"Yes, it is a group set up above to gather mathematical talents and let them shine and contribute in the field of mathematics." Chu Xianming paused when he said this, "I told your senior brother about your situation. ”

"Huh?" Su Qingyun didn't understand what the teacher meant.

Immediately after, Su Qingyun saw Chu Xianming take out a ...... from the drawer Paper?

"This is ......," Su Qingyun had a faint guess in his heart.

"Qingyun, your mathematical talent is very high, you shouldn't be buried in such a small place." Chu Xianming pointed to the test paper, "This is the test paper for the recruitment of their mathematics talent group sent by my senior brother, you do it, and send the test paper over when you are done." ”

"I hope that you can also join this math talent group, this is a great opportunity to exercise."

"Teacher, this ......" Su Qingyun frowned slightly, a little hesitant.

"What? Think you can't do it? Chu Xianming said deliberately, "Wasn't you so confident just now?" ”

"Of course not." Su Qingyun said, "I just don't want to leave here for the time being." "This level of mathematics talent group will definitely focus on studying and researching, then she will definitely leave here, for the time being, she doesn't want to.

Chu Xianming was stunned for a moment and smiled, "Qingyun, are you thinking too far?" I'm just going to let you do these questions first, so that you can see where you are in the gap with this group of math talents? Not to mention that you haven't been recruited by this talent group, even if you are, you have a choice. ”

"Don't think too much about it, just treat it as if it were a simple exam to complete."

After Su Qingyun listened, she was a little stunned, she seemed to be really used to seeing one thing and seeing the end, but she forgot that the person who decided whether to take this road or not was herself, and there were many opportunities to stop in the middle.

"Teacher, it's me thinking too much." Su Qingyun was a little ashamed.

"Let's do the question." Chu Xianming didn't continue, he glanced at the time, "I'll time you." ”

Since it is said that this is an exam, then it must be timed.

Su Qingyun nodded, picked up the test paper, abandoned the distractions in his heart, and began to concentrate on reading the questions and answering.

At a glance, Su Qingyun couldn't help but be shocked, sure enough, it was the mathematics talent group above, although there were only three questions in the entire test paper, but the difficulty of these three questions was not an order of magnitude compared to the questions assigned to her by Chu Xianming before, and the knowledge of mathematical principles contained in them was even more all-encompassing.

This test paper requires the respondent to have a deep mathematical literacy and strong mathematical ability, and it is by no means an easy task to solve these questions.

Su Qingyun cheered up the spirit of 120,000 points and began to calculate the problem.

Chu Xianming had been observing her expression, and when he saw that she had finally begun to get serious, he nodded in his heart, he was a good student, but he was a little stuck here, he had to push her, let her go out, and show her strength in a place that suited her.

It's not that he doesn't want to keep her, but in today's society, the situation is changing rapidly, next year, she will graduate from high school, and he, as a teacher, must find a good way out for her.

He definitely didn't want to see Su Qingyun's talent buried.

Su Qingyun, who was concentrating on arithmetic, naturally didn't know her teacher's love and foresight, she only felt that the passion all over her body had been ignited, she hadn't had this feeling of being challenged for a long time, and it was worthy of a national-level selection.

Her eyes lit up amazingly, and she was immersed in the world of mathematics and couldn't extricate herself.

Chu Xianming saw that she had completed the first question, and a trace of satisfaction flashed in his eyes, and he knew that with Qingyun's ability, he could solve these questions.

He didn't bother Su Qingyun and let her concentrate on the problem.

The library was extremely quiet, and time passed minute by minute, until more than an hour later, Su Qingyun finally put down the pen and said with a radiant look: "Teacher, I'm done." ”

"Hmm." Chu Xianming took her test paper, didn't look at it, folded it directly, "I will send this test paper back for your senior brother to see, I don't judge right or wrong." ”

Su Qingyun blinked, "Okay, I'll listen to the teacher." ”

"That's all for today." Chu Xianming said kindly, "Aren't the family still waiting for you?" Let's go back. ”

Su Qingyun looked at the time and was startled, it was all at this point, and the grandmother and aunt didn't know how long they had been waiting.

She picked up the homework assigned by Chu Xianming for her, and ran away, "Teacher, I'll go first." The voices were scattered all over the place, and everyone ran out, as if there was still a remnant of the voice.

Chu Xianming smiled, no matter how powerful he was, he was still just a child.

He looked at the folded test paper in his hand, his smile deepened, and he didn't delay, and soon, he sent the test paper back to Chen Zheyu, the provincial capital, along with a letter that had been written a long time ago.

Chen Zheyu, who received the letter and the test paper, was stunned, at first, the teacher asked him to send a copy of the test paper for his selection exam, he thought that the teacher wanted to take a look at these questions by himself, but who can tell him, why did the letter sent back by the teacher say that his little sister had completed the test paper and let him show it?

His little sister? Chen Zheyu subconsciously recalled Su Qingyun's face, after a brief meeting that day, in his heart, his impression of Su Qingyun was just a junior sister with a beautiful appearance and a good personality.

Although she knows that since the teacher accepts her as a student, she must have something special, but this does not mean that she can make this question?

How old is that girl? Didn't you say you're still in high school?

Was it the teacher who underestimated the difficulty of these questions, or was his little sister really amazingly talented? Chen Zheyu thought about it and shook his head, no matter how amazing his talent was, it should be impossible to complete this test paper.

However, Chen Zheyu still opened Su Qingyun's test paper, since it was something entrusted by the teacher, he definitely had to do it.

When his eyes came into contact with Juanxiu's handwriting on the test paper, Chen Zheyu, who only wanted to take a cursory look, instantly froze his gaze, his eyes widened in disbelief.

"What's wrong with you?" The colleagues around him looked at him strangely, "I have entered the math talent group, are you happy and stupid?" ”

"Don't talk!" Chen Zheyu snorted, and his eyes were still glued to the test paper like glue.

The colleague was startled and shut his mouth.

How can it be? How can it be? Chen Zheyu watched all of Su Qingyun's problem-solving processes, and his hands holding the test papers were shaking, how could they all be correct? Moreover, the method she used was very novel and simple, and it can almost be said that she solved these three problems in the most perfect way.

How the hell did she do it? Chen Zheyu's mind was blank, did she answer these three questions with the help of her teacher, or did such a genius really exist in this world?

Chen Zheyu suddenly pulled out the teacher's letter again, and his eyes were fixed on a certain sentence inside.

"All the test papers were completed by Su Qingyun independently in an hour and a half." After he finished reading this sentence, the whole person was already breathing heavily, and his face was swollen red.

He understands the teacher, no matter which student he likes, it is impossible to cheat, which shows that this test paper was really completed by his little sister alone, and it was still in an hour and a half!
