Xu Mang has always defined himself as a profitist, everything is based on his own interests, if what he does does not get benefits, Xu Mang will never do it.

however

This time, he broke his own concept, just to vent his anger for Yang Xiaoman.

"Alas!"

"Can you borrow a pen and paper?" asked Yang Xiaoman, who was listless next to him, "I suddenly had an explosion of inspiration and wanted to make a painting." ”

Yang Xiaoman, who was angry, glanced at Xu Mang, and when he saw the serious look on his face, his anger disappeared a lot, the only good thing about this guy was that after seeing his innocent face, he would suddenly be a lot happier.

After getting the paper and pen, Xu Mang silently walked to the last row and began to solve the problem.

For Xu Mang,

Liang Feng only had a trace of illusion left, and now he just didn't make trouble.

"Since Lin Mengjie has solved this problem, then I will also talk about the difficulties of this problem. Liang Feng said: "Lin Mengjie... Listen carefully, too!"

"Got it, teacher!" Lin Mengjie nodded.

The king's bureau between women is just point-to-point, not like some popular bureaus, who come up and pull each other's hair first, and then pull each other's clothes wildly, to the point of death.

Fight but not fight, this is the king!

Lin Mengjie was very happy, she believed that after this firefight, Yang Xiaoman would give three points when she saw her, what if you are beautiful? What if you are the first in the whole grade? What if you are the first in the city?

I'm sorry!

You'll never be able to solve that question!

Although this is not done by yourself, the answer is to hand it over to Mr. Liang yourself!

"Ahem!"

The difficulty of this problem is that it is very comprehensive, and in Lin Mengjie's way of solving the problem, she uses the Hesse matrix to find the extreme value of the multivariate function, which uses linear algebra and multivariate function differentiation. ”

"Look at the blackboard!"

Liang Feng used a projector to project Lin Mengjie's answer onto the blackboard.

"Here... There... And then..."

Liang Feng began to explain.

At this point,

Xu Mang was cracking this super difficult geometry, his hand speed was still breathtaking, and he didn't calculate it at all in the process of solving the problem, and directly gave a number, without any intention of stopping in the middle.

Ten minutes later,

Liang Feng was still explaining the topic, and Xu Mang was already about to go crazy because his hand was about to break.

Oops...

How can there be?

No, no, no, my hands are so sore!

"Xu Mang?"

"What are you doing?!" Liang Feng glanced at Xu Mang, who was sitting alone, he was shaking his arms wildly at this time, and couldn't help but say, "Don't shake it off, if you throw it down, your arms will fly!"

"Oh..."

Xu Mang once again embarked on the road of solving the problem.

For forty minutes,

Liang Feng finished talking about this topic, looking at the serious looks of the four proud protégés, Liang Feng was very pleased, but... glanced at Xu Mang, who didn't know what to do in the back, this heart was cold.

"Take a five-minute break!"

Words fall,

Xu Mang also completed the last step.

Finish!

I'm so tired... Doing math problems emotionally requires physical strength.

As soon as Liang Feng left, the atmosphere in the classroom gradually condensed, and even time stopped, Li Hua and Cheng Tianjie felt the danger and consciously left the classroom.

"Yang Xiaoman?"

"Do you know that question now?" Lin Mengjie asked with a smile, "If you can't, I can teach you." ”

"You seem to be very enthusiastic... But look at you a little mean. Yang Xiaoman said expressionlessly: "Although I won't, I tell you, as long as I, Yang Xiaoman, am in school, you will never be the first!"

"Humph!"

"What about the first?" Lin Mengjie snorted coldly: "If you have the ability, you can solve that problem!"

"I'll show you!"

Yang Xiaoman is on top... Just like she does in the game, others can lose, but she has to win, otherwise she will be very unhappy!

Xu Mang sat in the back row trembling, but it was not without gain, Xu Mang realized that Yang Xiaoman was not as strong as she appeared, she also had weaknesses, her pride.

Just like a diamond, it is hard, but it is also brittle.

As long as you have any ability that surpasses Yang Xiaoman, she will explode on the spot, because her pride does not allow her to be weaker than others, even if it is just an inconspicuous ability.

Xu Mang sighed, sometimes you still need to be soft.

"I'm back!"

Xu Mang sat beside Yang Xiaoman with a smile and greeted him cordially.

"Get out!"

"The old lady is very busy now, so I didn't pay attention to you!" Yang Xiaoman lowered his head and was writing the steps to solve the problem.

Xu Mang silently handed a stack of papers in his hand to Yang Xiaoman, and said nonchalantly: "Here you are... What you want. ”

What the?

What do I want?

Could it be... Be... So what?

Yang Xiaoman suddenly blushed, not knowing how to respond to Xu Mang, and said grindingly: "You... You always surprise people like this when I'm busiest... Necrotic!"

The sound is so small, so small that only each other can hear it.

"Hey, hey!"

"You don't look at who I am!" Xu Mang suddenly became arrogant, he obviously misunderstood what Yang Xiaoman meant, "Hurry up and take a look!"

"Nasty!"

"It's... This... Go home and see it!" Yang Xiaoman glanced at him, hurriedly put the 'love letter' handed over by Xu Mang into his bag, and said with a smile: "Finally know how good the old lady is?"

Alas?

Alas?

What's the situation?

Is there a deviation in the conversation between us?

I'm supposed to be human, right?

You just said that it was human language, right?

Don't... Is Yang Xiaoman an alien?

Not to mention,

How can a normal woman have such a flat chest!

"Yang Xiaoman?"

"Huh?"

"Actually, your real identity is a shorty flat-chested star, right?" Xu Mang asked curiously, "The purpose of your coming to Earth is to change the genetic defects of your people?"

Yang Xiaoman: (* ̄〈 ̄)

The old lady can see it... It's about giving you a candy and then giving you a slap in the face!

"Did you buy the bruising medicine?"

"Bought it..."

"Good!"

"Later, if I take too heavy a shot, I will take care of you for the rest of your life, don't worry!" Yang Xiaoman said expressionlessly: "Now you can shut up, the old lady has to do the question!"

Looking at Yang Xiaoman's serious way of doing the question, Xu Mang's scalp was numb, it was obviously a very simple thing, why was it so complicated?

Then

Li Hua and Cheng Tianjie returned to the classroom, and then Liang Feng also arrived.

"Report to the teacher!"

Yang Xiaoman solved the problem yesterday, but she didn't want to take it out. Xu Mang bravely stood up and said to Liang Feng.

Yang Xiaoman was shocked!

Lin Mengjie was also shocked!

"Oh?"

"Yang Xiaoman has already made it?" Liang Feng asked with a smile: "Since it has been made, then take it out generously, and we will analyze it together." ”

"I... I..."Yang Xiaoman squeaked and couldn't say half a sentence.

"Report to the teacher!"

"It's in her bag!" Xu Mang reminded.

Yang Xiaoman was about to collapse, if anger was a bullet, Xu Mang would have been shot more than 5,000 times.

Damn it!

The old lady must kill you at night!
