Wang Zixin has not paid attention to who Xu Rui is, these days she has been immersed in hard study, love and love, she is not very good at it.

Looking at each other, Xu Rui had a gloomy face, packed his schoolbag and wanted to leave.

"Hey, Xu Rui, what are you doing, Zixin's academic performance is up now, you are her motivation for learning, besides, there is no other seat, we promise not to disturb your study."

Wang Zixin looked at Li Meng strangely.

Interesting, when did I say that Xu Rui was her role model?

Xu Rui glanced at her coldly, put on the headphones, and did not squint, as if there was no one around.

"Zixin, give it, you read a good book, I'll treat you to ramen at noon."

Li Mengsai gave her a romance, "One Child and Ten Treasures: The President's Husband's Presumptuous Pet"?

Pigs? Ten in a litter? What a mess? This kind of book is also read?

She returned it to Li Meng.

"What's wrong? Don't you really want to read this one? Li Meng asked in surprise.

"I don't want to watch it now."

Li Meng looked at her and said meaningfully, "Zixin, you have changed a lot now. ”

"People change."

Put it away, Li Meng picked up the history book absentmindedly, and his eyes peeked at Xu Rui opposite from time to time, and it took a while to calm down and study.

These all fell in Wang Zixin's eyes, and she smiled contemptuously.

Time passed quickly, and when she racked her brains to solve a math problem, the paper in front of her was suddenly withdrawn.

"Xu Rui, you can help Zixin, she was stumped."

Wang Zixin looked at Xu Rui and then at Li Meng.

Near noon, many people went out to eat, and a small number of people whispered and took the opportunity to rest.

For the sake of face, Xu Rui had no choice but to take it, and after taking a look, he took a pen and calculated on paper, and quickly threw the roll over.

"Thank you, Xu Rui."

Li Meng grabbed the straw paper first, pretended to look at it for a long time, and then said, "Xu Rui, why don't you tell Zixin about it, I didn't understand it, and I can't explain it to her." ”

What do you explain?

At this time, in Wang Zixin's heart, there were a thousand Cao Nima rushing by, this Li Meng, is there too no sense of boundary?

She looked at Xu Rui again, and had to say that he was very good-looking, he could be regarded as a colonel, he studied well, had a good family background, looked good, and his temper should be very good.

There was no way, Xu Rui had no choice but to lean over half of his body and spread the roll in front of Wang Zixin.

"Knowing ...... from known conditions"

He spoke quickly and thought clearly, and if she hadn't had a bit of a mathematical foundation, she wouldn't have been able to grasp the meaning of his words.

"Do you understand?"

Xu Rui habitually asked, and regretted it a little after speaking.

He regarded her as a student in the top class, a scumbag, even if he wanted to pick up the lost knowledge, how could he keep up with the thinking of the top students.

Wang Zixin didn't look up, she was looking at the steps Xu Rui wrote on the paper.

"Oh, I understand, Xu Rui, you're thirsty, give it, this is my own herbal tea, defeat the fire, the library is too heated, drink something to moisten your throat."

Xu Rui didn't answer, glanced at Wang Zixin, who was still reminiscing, and sat back in his seat.

Li Meng had a look on his face, and finally put the herbal tea in his schoolbag.

"Zixin, don't force yourself, it's hard to learn advanced mathematics without mathematical thinking."

"Don't make a noise!"

Wang Zixin rudely interrupted her, and her thoughts came back, and she suddenly became enlightened.

"I understand, Xu Rui, do you think I can change this formula to another one?"

In Li Meng's stunned gaze, she quickly wrote down a series of symbols and handed them to Xu Rui.

Finally seeing a hint of strangeness on Xueba's face, he glanced at Wang Zixin approvingly, and said the first sentence to her, "It's indeed simpler than my formula." ”
