Tang Xiaoya was aggressive.

"You're that skilled?"

Liu Sen couldn't tell.

"If you want to misunderstand, you can misunderstand, anyway, I can swear you're the first girl I've detained. ”

I swore that this kind of thing would really work for girls, and she actually believed it for eight points.

Liu Sen quickly stretched out his hand.

She let out a scream.

"I swear you're still the first girl I've ever unraveled. ”

"You go die. ”

Tang Xiaoya had no choice but to drag one hand behind her back, and one long leg was eager to kick Liu Sen to death.

He buttoned her up again.

"The second girl I buttoned up was you. ”

Along the way, she was all tiger-faced, until she reached the door of the girl's apartment, she didn't speak, she was angry, Liu Sen said: "This is all sent to the door, I can rest assured when you go back, what, remember to buy a new size early." ”

"You stinking shameless thing, shut up. ”

"Actually, I had a question, and I held it all the way. ”

"What?"

Girls' curiosity is important.

"You are wearing 81C now, you bought it during the winter vacation, it has only been more than four months, you have grown to 83D, you may have eaten a lot of chickens with hormones, and you will have to eat less in the future. ”

"You die. Tang Xiaoya was ashamed and embarrassed, and she didn't know why she was getting bigger again, glaring at Liu Sen, "You're not a good thing." ”

"Hi, Xiaoya. ”

A girl with long hair came over, holding a boy in her hand, very elegant and full of bookish atmosphere, and when she saw the two of them slightly embarrassed, she also said hello.

"Hi, Xiaoya. ”

The girl smiled sweetly and looked cute, "You are our Xiaoya's little boyfriend Liu Sen." ”

Liu Sen touched his chin and said very smugly: "Tsk, am I so famous now?

The girl giggled, "I am in the same dormitory as Xiaoya, the best friend, my name is Zhu Zhu, this is my boyfriend Xu Zhu, the pronunciation of our names is the same, it's very fateful, right?"

"That's not just fate, the two of you go to this station, it's just a pair made in heaven, a pair set on the ground, even I look at it and envy Senior Xu Zhu. ”

Liu Senle said that since the arrival of the two, Xu Zhu has been providing jealousy energy, reaching 300 in a few minutes, his emotions are quite abundant, and the balance of spiritual power has exceeded 22,000 points, and his inner sense of security has suddenly increased.

Zhu Zhuzhi grinned and praised: "The little boyfriend's mouth is too sweet, no wonder he can catch up with our Xiaoya." ”

"Where, I think it is Senior Xu Zhu who chases you is a great skill, which makes the younger brother envious. ”

Zhu Zhu laughed, covered his mouth and smiled, "Liu Sen, I think Xu Zhu envies you, he chased our Xiaoya before, Xiaoya didn't look down on him, so he was cut off by me." ”

And then there's this triangle.

Tang Xiaoya didn't like to talk about this, and scolded: "Go back." ”

Liu Sen said: "Xiaoya, how can you be so fierce to me, outside, you have to give me some face, hehe, but I don't care, I like you like everything." ”

As he spoke, he put one hand around her shoulder, and his hand was just in the place where she buckled, and the threat was obvious, Little Pepper, if you are disobedient, my brother can untie it.

Tang Xiaoya was furious, hating to kick this nasty guy to death.

Sure enough, Xu Zhu provided another 200 points, I wiped it, and he was another emotional guy, and he was still worried about his girlfriend.

Zhu Zhu proposed to meet on the weekend to watch the dragon boat race together, and went out by the way.

Tang Xiaoya wanted to refuse, but Liu Sen agreed with a smile.

After the two left, Tang Xiaoya glared at him fiercely, "You still need training, what do you promise?"

"You can't learn all the time, your brain is stupid, don't worry, I will deal with it properly from Mr. Li. ”

"That's not going to work either. ”

"Then you can explain to Zhu Zhu. ”

Tang Xiaoya snorted, Zhu Zhu is a member of the student union organization committee, and it is difficult to shirk to her not to participate in the event, and she has no idea for a while.

The selection of the provincial team is actually very intense, much more intense than the provincial mathematics league.

According to the current policy, the provincial first prize is of little use, but the members of the provincial team will inevitably be able to send them to Tsinghua University in Beijing or Jianghai University in Jianghai.

There are 9 members of the provincial team in Hui Province, the strength of the first five is too strong, and the competition for the last four places is the most fierce.

Everyone is engaged in promotion and competing for places.

Liu Sen asked Li Jie about asking for leave.

I thought that Mr. Li would definitely refuse sternly, but I thought about a lot of reasons behind it.

Li Jie turned his brain, thought for a moment, and said: "I can't control the affairs of your young people, but if you ask for leave to go out to play, other classmates will have opinions, and you must convince other classmates." ”

"How can I be convinced?"

"Fight. ”

Li Jie said the rules, Liu Sen agreed, and if he fights, he will fight, who is afraid of who.

Don't pretend to be forced, don't be in the limelight, how to earn spiritual power, this special time to travel to the magical academic world requires 10,000 spiritual power, the loss of photons gives Liu Sen a very insecure feeling, there are not a few thousand spiritual powers, and he can't sleep steadily.

In the training classroom, Li Jie walked in, the students were quietly doing questions, he explained the selection rules of the provincial team, a 7-week training, a selection exam a week, and finally a comprehensive selection of seven results.

The students became nervous.

Li Jie also said: "Liu Sen wants to ask for leave this weekend, the nature is very bad, considering that the classmates are definitely not convinced, so he is willing to fight, before this weekend, any of you can give him a question, if he can't answer by then, he will not be allowed, if he answers, he must also explain the Fa in public." ”

Only one person in Hui Province enters the national team every year, and the performance is not good, Li Jie wants to sharpen Liu Sen and focus on training, but no one in this class is his opponent, so he has to use this method to stimulate the fighting spirit of this kid.

Liu Sen stood up and arched his hand and said, "Welcome to your teachings." ”

Yu Hanming and Zhang Qian both frowned and pondered.

Yuan Bin said: "Since everyone is humble, then it is up to me to throw bricks and lead the way." ”

He went to the blackboard and wrote a problem: prove that there are two irrational numbers x,y, so that z=x^y is a rational number.

Liu Sen stepped forward and looked at it for a moment, and said: "You can use the method of counterproof, assuming that for any two irrational numbers x, y, z=x^y are irrational numbers, then √2^√2 must be irrational numbers, (√2^√2)^√2 is also an irrational number, in fact, this result is that 2 is a rational number, and the contradiction is obtained, and the result is proved." ”

Yu Hanming pushed his glasses, stood up and said: "Liu Sen, your proof method is very ingenious, but it is not clear whether √2^√2 is a rational number or an irrational number, and the basis of your proof is the law of exclusion, what if √2^√2 is reasonable? I think you should prove this problem again, so that there is no loophole in the logic." ”

In the end, he is a scholar, and the angle is tricky and weird.

Li Jie was excited and said with a smile: "That's right, Liu Sen, this is equivalent to proving that the root number of a rational number to the second power cannot be a rational number, and you can't just use an example to prove it." ”

Yuan Bin originally looked at Liu Sen from the same school, so he came up with an entry-level simple question, but he didn't expect to pull out the problems behind him, and he felt a little guilty in his heart.

The collective concept is very interesting, in Gyeongju No. 1 Middle School, the two are competing with each other, but when they get here, Yuan Bin thinks that Liu Sen is his own person.

Liu Sen stood on the podium and pondered.

Yu Hanming sat down.

Li Jie was interested, he knew the proof of this question, and said in his heart, it was best to give this kid a dismount, and put away the thoughts of going out to wave, don't think that a perfect score in the selection competition is great, and the mathematics is broad and profound.
