Zhao Xiancai was writing and talking. Before he could finish speaking, the door to the dormitory was opened, and it was his roommate from Magic City Middle School who came back.

When he passed by Song Liqun and the others, he glanced at what Zhao Xiancai was writing and asked casually: "What question are you doing here?"

"Zhao Xiancai asked the question himself." Song Liqun replied casually without raising his head, and continued to listen carefully to what Zhao Xiancai said.

Although the roommate from Modu Middle School who was originally planning to go to bed pretended to ask casually, he was actually listening carefully to what Zhao Xiancai said.

When he just got on the bed and lay down, Zhao Xiancai also finished explaining the topic.

"If you want to do it in advance so much, then solve this problem first. This problem is enough for you to spend some time."

After explaining the content of the topic, Zhao Xiancai said to Song Liqun and others.

Zhang Qiuyu, who had already gone to bed beside him, had just finished listening to the part of the topic that Zhao Xiancai said. He was also a little interested, so he came down and said to Zhao Xiancai and the others: "Can you show me the topic?"

"Give."

Seeing Zhang Qiuyu's interest, Zhao Xiancai handed it to him without saying anything.

After taking the draft paper handed over by Zhao Xiancai, Zhang Qiuyu took out his mobile phone and took a photo, then returned it to Zhao Xiancai.

Song Liqun and others began to think about how to solve this problem.

Zhao Xiancai took out a mathematical analysis textbook he brought over and began to read it carefully.

Just like that, the dormitory returned to peace.

The only sounds that can be heard are the sound of writing, turning of books, and the sound of the wind blowing outside the house.

After a while, Zhang Qiuyu, who was lying on the bed, got up from the bed again and left the dormitory.

"This is a question asked by a teammate from Wanhui Province in my dormitory. I have been thinking about it for a long time without any clue, so I came to ask you."

After Zhang Qiuyu left the dormitory where he lived, he came to another dormitory. The four people living in this dormitory were all from their Magic City Middle School, and their CMO competition results were all better than Zhang Qiuyu's, and there were even two

Got full marks on the exam.

Four teammates from Modu Middle School in this dormitory were curious and prepared to take Zhang Qiuyu's phone to see what the questions were.

However, Zhang Qiuyu did not give them his mobile phone, but said to them: "I will send this question to our group first, so you can take a look."

In this way, the silence that originally filled Zhao Xiancai's dormitory quickly spread to this dormitory.

"Tsk...I can't think of any good solution to this question right now. Where are you, Senior Ding?"

A student wearing glasses who seemed slightly younger than the others said to another student next to him who looked taller.

"Oh, I've told you several times that although I'm in a higher grade than you, you'd better not call me senior when it comes to math.

I feel ashamed even if you call me senior, you should just call me by my name.

I can't think of any good solution to this question at the moment.

What is the name of the question maker who lives in the same dormitory with you?"

The person called senior first said to the student who looked younger, and then asked Zhang Qiuyu.

"His name is Zhao Xiancai, and he comes from Chengxian No. 1 Middle School. I have never heard of this school. The other three people in the dormitory where I live are all from Wanhui Province, and the other two are from Luzhou No. 1 Middle School." Zhang Qiuyu

explained.

"Zhao Xiancai? It's actually him."

As soon as Zhang Qiuyu said Zhao Xiancai's name, Zhang Qiuyu's classmate was surprised at first, and then said with his original expression.

"Have you heard of him?" Zhang Qiuyu asked curiously.

"When I participated in the CMO competition before, I heard a classmate from the sophomore high school affiliated to East China Normal University talk about him, saying that he seemed to use two solutions to every question during the exam.

[By the way, the best app for reading and listening to books is currently Yeguo Reading, install the latest version on yeguoyuedu.]

And later, after the CMO results came out, he also got perfect scores.

As for the high school he went to, it’s normal if you haven’t heard of it. Chengxian No. 1 Middle School is an ordinary high school in a poor county in Anhui Province and is really not famous.

But I have to say that he was indeed the biggest dark horse in Anhui Province in last year's mathematics league.

I don't know much about him. You live in the same dormitory as him. If you want to know anything about him, you should ask him yourself.

You go back first, and we will tell you when we figure out the solution to this problem."

After the classmate finished speaking, Zhang Qiuyu returned to the dormitory where he lived.

After Zhang Qiuyu returned to the dormitory, he was also very interested in Zhao Xiancai, so he searched the chat records in some math competition groups he had joined to see if anyone had talked about the name Zhao Xiancai, and checked it on the Internet.

The situation of the Mathematics League in Anhui Province last year and the year before last.

Finally, he finally understood why his perfect-scoring classmate said that Zhao Xiancai was the biggest dark horse in Anhui Province.

"Um...Zhao Xiancai, can you do this question yourself?"

After getting to know Zhao Xiancai a little, Zhang Qiuyu started talking to Zhao Xiancai.

"Yes." Zhao Xiancai replied.

This conversation has a beginning, and it will be easier to talk about later, but the conversation is mainly about Zhang Qiuyu, and Zhao Xian listens.

Most of what Zhang Qiuyu said was about their Magic City Middle School.

I have to say that this city is worthy of being a strong competition city. From 2008 to 2013, every year there are people who can enter the national team and participate in IMO competitions.

Moreover, in the past few years, those who have entered the national team in Modu City are all from Modu Middle School.

"Just now I asked the two math masters in our school, even they didn't know how to solve your problem.

These two are real masters, especially Gao Peicai, who is only a freshman in high school this year, but whether it was the previous preliminary round, the first test, the second test of the league, or even the previous CMO exam, he got full marks...

"

As soon as the name Gao Peicai was mentioned, the roommate of the Magic City Middle School became extremely excited, as if it was not Gao Peicai but himself who got perfect marks in the exam.

The Gao Peicai he was talking about was the one who looked younger than the others in the dormitory he went to before.

"Only a freshman in high school?

At the end of the CMO exam, while eating, he said that there must be a lot of perfect scorers this time, was it him?"

Song Liqun and the others, who were thinking about the test question asked by Zhao Xiancai, were surprised when they heard Zhang Qiuyu say that the math master in their school was only in the first year of high school and asked him.

"Yes, that's him. It turns out you were also there last time."

Hearing that Song Liqun and the others seemed to have met Gao Peicai, Zhang Qiuyu became even more interested.

"Let me go, isn't this better than you? You are now a sophomore in high school."

Yao Ruzhou was also surprised and said to Zhao Xiancai.

"He's only a freshman in high school? It's impressive enough that he can achieve such results in his freshman year of high school. When did he start learning about mathematics competitions?"

Zhao Xiancai was obviously a little surprised after hearing Zhang Qiuyu say that Gao Peicai, the math master in their school, was only in his first year of high school.
