Originally, Liu Yun'er didn't have hope, after all, this was beyond the scope that she and Lin Fan could understand, both of them were engaged in physics... For pure mathematics, it should not be studied very deeply, as long as it can solve problems.

outcome

At this time, I heard a sentence from the big fool... Baby, do you want to win?

Liu Yun'er looked at Lin Fan in surprise, her eyes flashed with anticipation, and an expression of disbelief, and even she was a little overwhelmed at the moment.

Similar to Tong Lingling is Tong Lingling, who also looked at her brother-in-law with a shocked face.

At this time,

Liu Yun'er didn't know how to speak, so she could only nod her head to express her emotions and thoughts.

"Just want to win. Lin Fan said with a smile.

“...”

"Brother-in-law?"

"You... Are you in... Are you kidding?" Tong Lingling asked cautiously: "It's not my sister-in-law, I look down on you, your girlfriend is a well-known physicist, and at the same time very accomplished in mathematics, but she can't do it... You're a library administrator, just... Don't join in the fun. ”

Lin Fan looked at Tong Lingling, still smiling, and said, "I just took a look, I think... The difficulty is not bad, there should be no problem. ”

"I..."

"This..."Tong Lingling said with a depressed face: "Brother-in-law... This is a grudge between me and my sister for more than ten years... Don't meddle, I'm a little embarrassed if I hurt you. ”

"It's okay, it's okay. ”

"Your brother-in-law, I... Won the first place in the Mathematics Olympiad since he was a child. Lin Fan smiled and waved his hand.

Tong Lingling was speechless, this is a pure mathematical problem, can Olympiad mathematics be compared?

"Okay, okay..."

"But don't be embarrassed to cry, and don't blame your sister-in-law for being ruthless. Tong Lingling sighed and said to her sister, "Sister... So, as long as my brother-in-law makes a question, I'll count you as a winner?"

however

Before Liu Yun'er could speak, Lin Fan asked with a confused expression, "What are you doing?"

“...”

"It's easier for you, brother-in-law!" Tong Lingling explained.

"Is there any mistake?"

"I used to be a top student, and I was the first in the math exam since I was a child... If my former classmates knew about this, they would laugh at me for being a scumbag. Lin Fan said angrily.

Tong Lingling was speechless for a while, and said in a squeaky voice: "Oops... Brother-in-law, that's not what I meant. ”

"Then what do you mean?" Lin Fan suddenly put on a posture and said seriously: "As long as I get a question wrong, even if I lose with your sister." ”

In a flash

The two sisters were stunned.

Liu Yun'er felt that Lin Fan was not lightly drunk, and when he had dinner, he didn't drink any wine, why did he start talking drunk now, and admit defeat if he made a mistake, what if he really made a mistake?

Compared with

Tong Lingling thinks her brother-in-law is crazy? Or is it... Is he too self-righteous? This is a question given by the world's top mathematics experts, and the difficulty far exceeds the highest level of the Putnam Mathematics Competition and the International Collegiate Mathematics Competition.

Outcome?

What did he say... Lose as long as you get one question wrong?

"Baby, give way. ”

"I'm going to start working on the questions. Lin Fan said to Liu Yun'er, who had a dull expression.

Hear Lin Fan's words? Liu Yun'er reacted at this time, and hurriedly pushed Lingling? Then sat to the side, and at this time... Tong Lingling also came back to her senses? Staring seriously at this 'self-righteous' brother-in-law of yours? Look how desperate he is.

When Lin Fan sat on the sofa and gently held the pen, instantly... It's like going back to the past, back to the time when I was chasing the wind.

Once?

Lin Fan as a college entrance examination candidate? I studied in the physics department of a university, and then as a physics student, I crushed a group of geniuses selected from math competitions, that is, since then... Lin Fan's supergod path calculation formula has officially started.

"Ahh

"That's how it feels!"

"It's back!"

Lin Fan held the pen and had no motivation? Instead, he raised his head slightly, closed his eyes and sighed? His face was full of emotion about life.

“...”

"Sister?"

"Is my brother-in-law crazy?" Tong Lingling leaned into Liu Yun'er's ear and asked in a low voice.

But facing the problem of your own little sister? Liu Yun'er didn't know how to answer, anyway... Does she feel like her man seems to be awake? Just don't know what time the awakening is? Historically? This so-called awakening is just a return to the light.

The next second,

Lin Fan is starting to write, and the first question is not difficult... Group Theory.

But soon he encountered the same situation as Liu Yun'er, he could only start writing a few steps, and then fell into a confused stage, because it was too abstract.

Wrong!

According to the author of the question, this should not be the case.

Lin Fan decided to start reverse thinking and find the answer to the question from the perspective of the questioner, and soon... He realized that he had been wrong from the start, and that he had been quite wrong, and that it was indeed a matter of group theory, but if you look closely... It's an exchangeable group, but it's a lot deeper.

Interesting!

It's so much fun!

The first question is so difficult, so what is the situation of the next three questions?

Lin Fan didn't dare to imagine the difficulty of the next question, anyway, he would say it to him... The king is fearless.

At this time, Lin Fan began to solve the problem, and the two daughters were stunned.

Liu Yun'er is very, very obsessed with Lin Fan's serious appearance, whenever he holds the pen, that meticulous appearance can pluck the most fragile string in her heart, at this moment... Liu Yun'er was numb.

However, unlike Liu Yun'er's infatuated man, Tong Lingling was a little confused.

No...

Is this made?

Tong Lingling watched Lin Fan's writing process, although compared to the standard answers she got, it seemed to be a little different... But the core idea is exactly the same.

I...

OMG!

A manager of a broken library actually solved a problem proposed by an authoritative expert in the field of mathematics.

Could it be that the brother-in-law is Will in "Soul Catcher"?

Ten minutes later,

Lin Fan solved the first group theory problem, and then glanced at the second problem, which was a problem about random processes, but Lin Fan found that this was not an ordinary random process, but a very special random process.

I don't know where to write!

Lin Fan pursed his lips, he didn't know how to solve the problem in front of him, every way of cutting in was a little weird, but it was very appropriate and accurate.

Just when Lin Fan was pondering,

Tong Lingling's heart is a little complicated, in fact, according to the previous statement, her cousin and brother-in-law have already won, but her cousin-in-law temporarily modified the victory conditions, and only when she gets all the pairs can she win, I originally thought... Just kidding, but the way he looks at the moment... It's not like a joke.

The first question,

My cousin can't even think of it if she wants to, but in her cousin-in-law's hands... It is easily solved.

He's really in my mother's mouth... That cousin-in-law who eats and waits for death?

"Oh!"

"I see!" Lin Fan suddenly realized: "I've been deceived!"

As soon as the voice fell,

Tong Lingling looked at her cousin-in-law, picked up the pen and began to write the answer on the paper, instantly... His face turned white.

Feed!

Brother-in-law!

Can we respect math?

Tong Lingling didn't know how to explain the scene in front of her, and the question that her mentor had thought hard about was in the hands of her brother-in-law... It took less than five minutes to solve it.

This...

This man is the devil, right?

however

What was even more excited was Liu Yun'er, if it weren't for the fact that there was a cousin by her side, she couldn't wait to throw herself into Lin Fan's arms and let him kiss her fiercely for five minutes... Not even a second less!

unconsciously

A quarter of an hour passed.

Lin Fan solved the second problem, at this time he already felt tired, this kind of high-intensity mental concentration had not appeared in Lin Fan's body for a long, long time.

"Baby..."

"Pour me a glass of water. Lin Fan was reading the topic, and said casually to Liu Yun'er beside him.

Hearing this,

Liu Yun'er said to her cousin on the side, "Pour a glass of water for your brother-in-law." ”

"Huh?"

"It's not..."

"Why am I?" said Tong Lingling with an annoyed expression.

"Why do you still talk so much nonsense under the fence?" Liu Yun'er said angrily: "Hurry up and pour a glass of water for your brother-in-law." ”

"I..."

ultimately

Tong Lingling went to pour Lin Fan a glass of water, and then... Lin Fan drank it all in one gulp.

The next two questions,

Lin Fan thought it was ridiculously difficult, but as a result... Compared to the first question, it is slightly weaker, but it is more computationally intensive, and at the same time it is very logical.

But

At this point,

Lin Fan's speed began to slow down, and the health math started.

Of course

Lin Fan didn't have a thorough health preservation, he should be quite serious.

Even so, Liu Yun'er was fascinated by it, she really liked Lin Da's pig's trotters so seriously, and she had a special charm that could not be spoken.

Half an hour later,

Lin Fan successfully solved the remaining two problems, and so far... Tong Lingling's four questions have been completed by Lin Fan.

"Oops..."

"I'm so tired!" Lin Fan put down the force in his hand, then stretched his waist, and then collapsed directly on the sofa, his eyes were blank and said, "What... Cousin, brother-in-law has already done it, you can check it, right? ”

Then

Liu Yun'er came back to her senses, she really couldn't continue to maintain that fragile reserve, even if her cousin was by her side, the next second... The big goblin pounced on Lin Fan's body and kissed him several times on the face.

"Big fool!"

"You're great!"

Facing Liu Yun'er, who suddenly got 'crazy heart', Lin Fan was a little overwhelmed, after all, there was an outsider present.

"Don't, don't..."

"My cousin is still there..."Lin Fan said shyly.

"Leave her alone!"

"When she doesn't exist... Hurry up and kiss me!" Liu Yun'er said urgently: "Hurry up, hurry up!"

In desperation,

Lin Fan kissed Liu Yun'er's flushed cheeks.

"Not here!"

"It's here!" Liu Yun'er's index finger tapped her lips lightly, and said with a hint of shyness: "The kind that Yan Shen came in!"

meanwhile

Tong Lingling took all of Lin Fan's problem-solving processes, looked at them carefully, and couldn't help but be even more shocked in her heart, there were no mistakes... Even more standard than the standard answer you get!

"Sister..."

When Tong Lingling turned around and was about to ask Lin Fan a few questions, suddenly... She saw a scene that broke herself.

OMG!

Don't let people live?!
