Looking at the stunned students and looking at the pair of hot eyes, Cheng Wanyi smiled slightly and said generously: "Hello students, I am Cheng Wanyi, your mathematics substitute teacher, and also your substitute class teacher. ”

"Wow... Really, great!" one of the male classmates couldn't help but cheer.

The others came back to their senses, and they didn't know who applauded first, and everyone applauded.

However, no one found out, what the hell is this applause?

"Welcome Teacher Cheng!" Wang Cunye shouted loudly.

"Yes, yes, welcome Mr. Cheng!" the others shouted as well.

Of course, the voice of the male classmates is especially loud.

Although students of this age are all in adolescence, most of them are still very simple.

Seeing a beautiful beautiful teacher, that is, simply liking and appreciating, beautiful things, everyone likes them.

"I'll go, if I can marry such a woman, I'm willing to live thirty years less!" Wang Cunye muttered.

Yang Xiaolei turned his head, glanced deeply at his tablemate, and said angrily: "Shameless!

"I..."

"Such a beauty should marry me, I will suffer a loss, and it is okay for young cows to eat old grass. Yang Xiaolei said to himself.

"Stinky and shameless!slut!" Wang Cunye immediately counterattacked.

"You don't understand, you look at Ouyang Chan, although she is beautiful, but she is still relatively immature, you look at Teacher Cheng, this is the perfect stunner, mature, intellectual, sexy..."

"You are cheap enough, you are very tasteful!" Wang Cunye was speechless.

Yang Xiaolei snorted and said with a smile: "That's necessary, it's much stronger than you." ”

"Your cheeks are so thick!" Wang Cunye knew very well that Yang Xiaolei would win compared to being shameless.

"What is cheekiness, is it delicious?" Yang Xiaolei narrowed his eyes and looked pleasant.

Cheng Wanyi has long been accustomed to this kind of gaze, and she has been like this since she was a child.

At this time, she looked at Zhang Wendi, then at Yang Xiaolei, and said, "Two classmates, why don't you ask me to solve the question?"

Zhang Wendi shrugged his shoulders and said, "Teacher Cheng, I don't care, I guess he can't?"

Without waiting for Cheng Wanyi to speak, Yang Xiaolei's face sank, and he said seriously: "Zhang Wendi, how many times have I told you, don't keep saying that you can't do it, pat your chest, and men should move forward bravely!

Zhang Wendi's face sank, when did I say that I can't do it, I mean you can't do it, okay.

At this time, he wanted to scold, but the new teacher had just arrived, and it was still such a beautiful woman, so he took a deep breath and endured it.

To maintain a demeanor, polite, gentlemanly man, in order to appear mature and steady, in order to leave a good impression on the other party.

This is what his father taught him, and Zhang Wendi has always kept it in his heart.

Cheng Wanyi frowned slightly, she naturally understood Yang Xiaolei's words.

It's just that her cultivation is very good, she lives in a scholarly family, she speaks and does things, and she has had a lot of rules since she was a child.

"Since you both have no opinion, then I'll give the question, this is an Olympiad math problem, listen up. ”

"Write down the 2005 natural numbers from 1 to 2005 in turn to get a multi-digit 123456789... 2005, excuse me, what is the remainder of this multi-digit number divided by 9?"

"Here are some pieces of paper and pen for you to calculate, and when you have done the math, you can write the answers on them, for the duration of one lesson, whoever answers correctly wins, and if they are all right, the person who takes the shortest time wins. ”

Cheng Wanyi put the notebook and pen in front of the two.

Yang Xiaolei smiled, took the pen and paper, and said disapprerovitically: "For such a simple question, you still use calculus, and the answer will come as soon as you open your mouth." ”

Cheng Wanyi raised her eyebrows, is this a somewhat frivolous student so powerful?

"This classmate, you already have the answer?" she couldn't help but ask, it hasn't been a minute since she came up with the question.

"Of course, it's a piece of cake. Yang Xiaolei smiled confidently.

The memory he had just gotten, when the question came out, it was automatically calculated in his mind, and it only took more than ten seconds for the result to come out.

"How is it possible? I was so confused that he didn't finish the numbers on the computer, and he figured them out?" someone held a mobile phone and couldn't help but retort.

"Silly, the calculator on the mobile phone, there are not so many bits, there are rules here, just look at it. The classmates beside him said angrily.

Cheng Wanyi looked at Yang Xiaolei quietly, she didn't know why, she had a feeling in her heart that this unattractive student might really be calculated.

But how is this possible?

The question she chose was a very difficult one in the high school math Olympiad.

Even those who participate in the Olympiad can not do it.

She also saw this problem occasionally and studied it for a long time before she solved it.

She really didn't believe that Yang Xiaolei could calculate the result.

"This classmate, self-confidence is a good thing, but you can calculate it in less than a minute, don't you think about it anymore?" Cheng Wanyi said with a smile.

Ouyang Chan next to her also frowned, Yang Xiaolei, this guy, is too arrogant!

In her mind, she was still thinking, where is the law, this guy actually said that the answer would come as soon as he opened his mouth.

Zhang Wendi lowered his head, the pen in his hand rustled and kept counting, and he devoted himself to the arithmetic without looking up.

Yang Xiaolei smiled, picked up the pen, covered it with his hand, wrote a number on the paper, and pressed it on the table with his backhand without waiting for others to look at it.

"In that case, we'll see. Yang Xiaolei sat down directly, looked at Zhang Wendi beside him, and said with a cheap smile: "Xiao Zhang, come on!"

"Don't bother me!" Zhang Wendi said without raising his head.

Yang Xiaolei folded his arms and closed his eyes.

I'm really sleepy, so I'll sleep for a while.

A few seconds later, Yang Xiaolei took a nap and snored slightly.

This scene made the other students stunned.

"Xiao Lei, even if you can't come out, you can compare it, you don't have to lose too ugly, you can't just give up!" Wang Cunye next to him suddenly became anxious.

Many of the classmates around him were also disdainful, and no one believed that Yang Xiaolei could calculate it.

Isn't it?

Zhang Wendi is the top student in the class, everyone is counting, but Yang Xiaolei is sleeping, writing an answer so that no one can see it, isn't this an obvious death?

Cheng Wanyi frowned, this guy was sleeping at this time, it was too much!

Ten minutes passed, and Zhang Wendi's forehead was sweating.

Twenty minutes passed, Zhang Wendi frowned, and still couldn't find how to disintegrate.

Half an hour passed, and Yang Xiaolei, who was napping, leaned slowly.

Suddenly, he was stunned, and the man came to his senses, almost falling to the ground.

"Hehe..."Many classmates laughed in a low voice, this guy has a really big heart.

Yang Xiaolei raised his head, looked at Cheng Wanyi and Ouyang Chan's unkind gazes, wiped away his saliva, and stretched his waist.

"I haven't figured it out yet, I've slept through. Yang Xiaolei shook his head and said with a disappointed face: "I said Zhang Shao, don't bother, I guess you can't figure it out, it's over, it's boring!"

As he spoke, Yang Xiaolei turned over the paper on the table.

On the white paper, a large circle is drawn.

"How is this possible?" Suddenly, Cheng Wanyi let out an exclamation.
