Zhu Xiaotong said: "This time, I joined a teaching team of Beijing University and came with my classmates. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 Every year, there are community organizations in Beijing University to teach in the western region. By the way, this is my classmate Cao Lekang, do you remember? ”

"Of course I do." Lu Yang glanced at Cao Lekang, and the other party also made the same move, both of them had disgust in their eyes, and they looked down on each other.

After chatting, I found out that Lu Yang and Zhu Xiaotong are quite related, and the other party also teaches mathematics, which is from Lu Yang's next class. Hearing that Lu Yang was teaching mathematics in class 3, Zhu Xiaotong said: "You also teach mathematics, it's great, I originally wanted to teach Chinese, but there was too little math teacher here, so I was transferred to the math group." I was fine with math in middle school, but I had forgotten a lot of things for too long, and I still had to tell these children......"

At the mention of this, Zhu Xiaotong said more, listening to her meaning, it seemed that the first class did not go well.

"No problem, my math knowledge is not bad, if you don't understand it, just ask me." Lu Yang patted his chest and said.

"Bragging!"

Cao Lekang scoffed at Lu Yang's assurance, in his opinion, Lu Yang was just talking big. Especially seeing his excited appearance in front of Zhu Xiaotong, Cao Lekang couldn't help but say what was in his heart.

Lu Yang looked at him, this guy had an inexplicable hostility towards him since the first time they met, and he still did it until now. He is not a fool, how can he not see Cao Lekang's thoughts about Zhu Xiaotong, it's just that I didn't chase Zhu Xiaotong, what do you mean by blowing your beard and glaring at me? Do you think buddies are easy to bully?

"Cao Lekang, don't talk nonsense." Zhu Xiaotong reprimanded lightly, she also had a headache for this classmate, she could say whatever she wanted, and she didn't look at people and occasions. The most important thing is that Cao Lekang's personality is very screwed, and he can't pull it back if he recognizes it. It's as if he likes Zhu Xiaotong and follows him all the time, without saying anything, from the capital to the northwest.

For Cao Lekang, Zhu Xiaotong has no love between men and women, and some are just admiration among classmates. Cao Lekang is indeed a very capable person, and in the past year with him, Zhu Xiaotong found that although the other party's EQ is not high, his IQ is surprisingly high, basically, as long as he wants to do what he wants to do, he can do it well.

Zhu Xiaotong also understands Cao Lekang's intentions, but she is very serious about love. If she refuses directly, with Zhu Xiaotong's character, she can't do such a thing. From time to time, she would give Cao Lekang some hints, but Cao Lekang always turned a blind eye to these hints, which made Zhu Xiaotong a little distressed. She didn't want to hurt Cao Lekang, but she didn't want to delay him.

"It doesn't matter, Cao is a graduate student of Beijing University, and it is understandable to look down on me as a high school student." Lu Yang laughed to himself.

Cao Lekang's eyes flashed: "Listen to what you mean, you have a strong confidence in your mathematical level?" ”

Lu Yang was a little annoyed in his heart, he originally didn't want to see the other party in general, but now it seems that it was his wishful thinking.

"Fortunately, classmate Cao is going to try it with me?" Lu Yang looked at him defiantly.

Cao Lekang helped his eyes: "If you dare." ”

The two college students didn't understand what was going on, but it seemed to be fun. Lu Yang and Beijing University graduate students compare mathematics, which is a new topic. Compared with them, Zhu Xiaotong is the most embarrassing one, and she is not Cao Lekang with low emotional intelligence, how can she not see that Cao Lekang is deliberately targeting Lu Yang because of herself?

"Forget it, Cao Lekang, you are good at math, this is something that the whole school knows." Zhu Xiaotong was worried that if Cao Lekang let Lu Yang not come to power, with Lu Yang's strength, who knows if he would retaliate against him.

Cao Lekang ignored Zhu Xiaotong's persuasion: "I studied business administration as an undergraduate, philosophy as a graduate student, and never studied mathematics, so I am not a bully compared to mathematics with Lu Yang." ”

Lu Yang smiled: "I admit that this competition is fair for both of us. When it comes to systematic education, our mathematics stops at high school. In terms of age, we are also comparable, so there is no such thing as who bullies whom. ”

The two parties reached an agreement, and Zhu Xiaotong completely understood that it was no longer something she could stop. So, the math competition, with only three spectators, began in a junior high school teacher's office.

The method of the competition is very simple, the two ask each other, and the scope is not limited, but the premise is that the two have mastered the knowledge. There was no referee in this match, as none of the three spectators had the ability to decide the result.

Cao Lekang looked at Lu Yang with no expression on his face, but his confident gaze revealed the thoughts in his heart. Although he majored in business administration and philosophy, Cao's attainments in mathematics are not shallow, even surpassing many graduate students in the Department of Mathematics at Beijing University. In his opinion, Lu Yang, who only has a high school degree, can't hold out for a round in his own hands.

Lu Yang is also full of confidence, he feels that he is a bit of a bully, who let him buy the knowledge of intermediate mathematics not long ago? In the division of Tiandao credit card, mathematics as a basic science is divided into five levels, from elementary mathematics, intermediate mathematics, advanced mathematics, master mathematics to grandmaster mathematics, these five levels correspond to the division of five levels of civilization. From this point of view, Lu Yang, who has intermediate mathematical knowledge, can already be regarded as the best mathematician on the planet.

A math lover and a mathematician compare math, and the results speak for themselves.

Facts have proved that miracles rarely happen, in Zhu Xiaotong's shocked gaze, in the admiring gaze of the two volunteer teachers, Lu Yang neatly defeated Cao Lekang, and then conquered the opponent with his profound knowledge. In the end, Cao Lekang bowed his head and admitted defeat, as for whether he was convinced or not, it is difficult to say.

"Is there really an omniscient genius?" Zhu Xiaotong really couldn't imagine this result.

"It's not that exaggerated, it's just that I'm usually more interested." Lu Yang said embarrassedly.

"After that, I'm going to have to trouble you a lot in math class." Zhu Xiaotong said with a smile.

"No problem." Lu Yang Road.

The two talked and laughed freely, only Cao Lekang next to him had a black face.

The life of volunteer teaching is very dull, because of the lack of teachers, all the teachers have substituted for several classes, in addition to the third class, Luyang also has one class, two classes, so calculated, an average of about five classes a day, is already very busy. Zhu Xiaotong is similar, she teaches classes 4, 5 and 6.

For the first time, Lu Yang felt this kind of busyness that was different from engaging in technical research, and he felt that his head was about to be empty. Every night, he had to prepare for class and correct homework, and rarely left school before 9 o'clock. Fortunately, he is not alone, Zhu Xiaotong's desk is next to him, and the two are often busy together until late.

"Lu Yang, how did you talk about this knowledge point?"

"Lu Yang, have you finished correcting your homework for those three classes? I still have a class here, can you help me correct it? ”

In this environment, the communication between Lu Yang and Zhu Xiaotong has increased significantly. Lu Yang found that Zhu Xiaotong was a very serious person, who usually corrected any small detail of his homework, and often asked students to come to the office to talk. She is beautiful and kind, and she quickly won the popularity of her classmates.

Lu Yang's work is also very good, mainly thanks to his knowledge. Lu Yang can talk about boring mathematics vividly and interestingly, and he can also explain those knowledge points that are not easy to understand very clearly, and his ability has also been recognized by students, and many students feel that after listening to Lu Yang's class, their interest in mathematics has increased a lot.

In addition to teaching, these young people from big cities also organize tours on weekends, which are not far from the Mogao Grottoes, and the first stop for everyone is the Mogao Grottoes. In addition, the Gobi and Huangsha in the northwest have also attracted the attention of these young people, which is a completely different scenery from the east and central part.

Lu Yang put aside other things for the time being, and devoted himself to life and work here with these young college students. After a few days of getting along, everyone was no longer in awe of Lu Yang as they were at the beginning, and they found that this young man standing at the top of the era was not as lofty as the legend, but very real and very approachable. In such a short period of time, although we did not become friends, we still got along very well.

The following weekend, Lu Yang and his family organized a camping camp in the Gobi, 30 kilometers east of the school. A hundred years ago, there used to be a river, but now it is gone, leaving only an empty beach that tells the story of history.

Lu Yang chartered a bus, which carried more than 20 young people towards the river beach. Behind the bus, four black off-road vehicles followed, this is Li Zirui and them.

It's hard to say what scenery there is in the Gobi Desert, and you can basically see it all at a glance. But that's not all, as everyone sets up their tents and takes out barbecue tools. When everything was ready, it was still early, and someone proposed to go to the river to look for stones, and everyone responded.

There are a lot of stones on the Gobi, what everyone wants to look for is the kind of "strange stones", the so-called "strange stones", refers to the natural formation, unusual stones, this is not ordinary you can define, in fact, you still have to give them human imagination.
