If I ask you to set up a stall, why do you always run to deserted places?

"It must be because I ate Chef Su's cooking!"

That's why my mind is so clear.

Lin Yue couldn't think of any other reason besides this.

But then again...

Is Chef Su's food really that outrageous?

Can it even improve IQ?

"Yutong, have you noticed that your brain works better after lunch?"

Lin Yue lowered her voice and spoke to Zhou Yutong beside her.

"Yes! Yes, yes, yes!"

Zhou Yutong suddenly raised her head.

"You think so too?"

"certainly!"

Lin Yue quickly handed over her test paper.

"Look, this is the derivative problem I just solved. I figured it out entirely on my own; I didn't copy the answer!"

"what?"

Zhou Yutong was startled.

She knows her best friend's capabilities better than anyone else.

How could one person possibly solve a derivative problem?

She quickly found the answer key and compared it with the answer key.

"Wow!"

"The answers are exactly the same!"

"Full throes!!"

Zhou Yutong was dumbfounded.

"Did you eat more than me at lunch? Why did you cook so fast?"

"I don't know either!"

Lin Yue scratched her head in disbelief.

"I think I ate a little more than you at lunch, but what does it matter?"

Can eating a meal really increase our IQ?

"No, no, no, it's unlikely to increase IQ."

Li Xiaoxiao, who was standing next to her, also came over.

She tilted her head and thought for a moment.

"But I feel like my thinking has become clearer!"

"Things that used to seem vague are now crystal clear!"

"Don't tell anyone!"

Lin Yue nodded in agreement.

"That's exactly how I feel, like I've suddenly had an epiphany!"

"You're all like this!"

Zhou Yutong's eyes were filled with shock.

How could all three of them have this feeling at the same time?

This can't be a coincidence, can it?

The group looked at each other.

Eyes wide open.

"I don't think that's scientifically sound!"

Zhou Yutong said softly.

"Don't we have any idea what our usual skill level is?"

"How could you possibly solve a math problem just by having a meal?"

"that is!"

Lin Yue nodded vigorously in agreement.

"Are you sure Chef Su didn't add anything to the rice?"

"Adding anything wouldn't cause this!"

Li Xiaoxiao rubbed her temples.

I feel like my worldview is crumbling little by little.

"Seriously! I don't think anyone would believe me if I told them!"

"Absolutely!"

"..."

They discussed it in hushed tones for a long time.

In the end, no one could provide a reasonable explanation.

"Never mind that for now!"

Lin Yue picked up her pen and took a deep breath.

"I'll try a few more questions; what if it's just a coincidence?"

"That's right!"

Li Xiaoxiao and Zhou Yutong also turned back.

"Maybe it's just a coincidence!"

No matter how delicious Chef Su's food is.

It's impossible to raise someone's IQ for no reason, right?

The three of them are notorious idiots.

I don't think I'll become smarter after eating a meal.

It's very likely that he fell ill from missing her so much these past few days.

And then, after finally getting what I wanted...

My mind suddenly clicked!

Ah!

That must be it!

Maybe it will be reduced to its original form in a little while!

The three of them didn't dare to be arrogant at all, and just continued to bury themselves in their problems.

at this time.

The classroom was quiet, with only the scratching sound of pens slicing across paper.

A little while later.

Lin Yue's ears twitched as she suddenly heard a noise behind her.

Zhao Ziliang lowered his voice and said, "Lin Yue."

Lin Yue turned her head.

What are you doing?

"you...."

Zhao Ziliang leaned closer, his nose twitched, and his expression was subtle. "You...you smell so good."

"???"

Lin Yue was stunned for a moment, then her face turned bright red.

"Are you fucking a pervert?!"

She grabbed an eraser from the table and threw it at Zhao Ziliang.

"no!"

Zhao Ziliang quickly dodged to the side.

The eraser smacked him on the forehead with a loud crack.

"Damn it! That's not what I meant! Don't talk nonsense!"

Zhao Ziliang rubbed his face and waved his hand with a wronged expression.

"What I wanted to ask was, what did you have for lunch?"

"Why does it smell so good?"

"what?"

Lin Yue paused for a moment, then looked down and smelled the sleeve of her school uniform.

Don't tell!

Sure enough, a faint smell lingered on it.

It smells like garlic pork ribs!

Lin Yue took a sip.

"Hmm!"

I feel much clearer-headed now.

It was probably a little oil stain that got splashed on during lunch.

It hasn't completely dissipated yet.

"It's that newly opened window."

Lin Yue asked, "Didn't you go eat?"

"What new window?"

Zhao Ziliang's expression changed instantly, as if he had missed something.

"Have any new food stalls opened in the cafeteria?"

"I didn't have an appetite at noon today, so I went to the convenience store, bought a bottle of water, and came back."

"Wow, you only drank water for lunch? Are you trying to lose weight?"

Li Xiaoxiao, who was standing next to her, turned her head, a hint of schadenfreude in her eyes.

"You really got ripped off!"

"A huge loss? What do you mean?"

Zhao Ziliang was taken aback.

"That window was opened by Master Su."

"???"

Zhao Ziliang almost jumped up.

He blinked and then blinked again.

"No! How could that be!"

"You're lying to me, right?"

"Did Master Su come to our school?"

Why would we lie to you? Master Su really is at our school!

Lin Yue nodded.

"No, how is that possible?"

Zhao Ziliang refused to believe it no matter what.

Master Su is a man who appears and disappears like a ghost.

How could they possibly travel all that way to set up a stall in their cafeteria?

Don't you have anything better to do?

Believe it or not, it's up to you.

Lin Yue proudly raised her chin.

Anyway, that's all I have to say.

"Holy crap!"

Zhao Ziliang couldn't hold back any longer. "Lin Yue, you can't lie to me like a puppy!"

"Who has time to lie to you?"

Li Xiaoxiao rolled her eyes at him.

The two of them turned around and went back to doing their homework.

Zhao Ziliang felt completely unwell.

What exactly did he miss?

Seeing him standing there in a daze, Zhou Yutong turned to him and said something.

"They weren't lying to you, we really did go and eat there."

"We had garlic ribs, steamed fish, golden broth beef noodles, and all sorts of rice bowls with toppings."

"The menu is so extensive it's impossible to count them all."

"Waaaaah!"

Zhao Ziliang was now completely convinced.

He let out a wail and leaned back.

He leaned back in his chair in despair, feeling more and more regretful the more he thought about it.

"How come I didn't know?"

Why didn't I go to the cafeteria?

"Why would I only drink a bottle of water at noon?"

His voice was so loud that several classmates around him turned to look at him.

"Zhao Ziliang, what are you howling about?"

"Yeah, what's with all this madness in broad daylight?"

"The academic pressure is too much, isn't it?"

"You guys! You don't know!"

Zhao Ziliang pointed at Lin Yue's retreating figure, heartbroken and filled with remorse.

"Master Su is here at our school! He's in the cafeteria!"

"They went to eat lunch today, but I didn't!"

"what?"

The students looked at each other in bewilderment.

"Master Su?"

"Are you talking about Master Su, the steamed bun seller in the air-raid shelter?"

"Of course! Who else could it be but him?"

"Holy crap! Really?"

"Really!"

"Damn it! I didn't go to the cafeteria today either!"

"I can't stand it anymore, I won't go for a long time!"

"Sixth Brother, why did you guys go to eat at Chef Su's restaurant behind my back?!"

"Exactly! Why didn't you say anything!"

"Are we still classmates?"

"..."

At this point, all the students couldn't hold back anymore and started shouting.

I wish I could slap myself across the face.

"Ugh, it's so hard to lose weight!"

Zhao Ziliang's face was filled with remorse, and he clutched his hair with both hands.

If God gave him another chance, he would definitely go to the cafeteria for lunch today!

Just then.

A loud shout came from the podium.

"Zhao Ziliang!"

Math teacher Liu Xiang walked in at some point.

He was staring wide-eyed at the complete chaos.

What are you all whispering about for?

"And Li Xiaoxiao, what are you three doing?"

All three of them shrank back simultaneously.

No, they didn't shout!

This math teacher's bias is way too extreme!

"I've been lecturing until my throat is dry, and you're all having a tea party in the back?!"

Liu Xiang threw the chalk onto the podium, his expression quite gloomy.

"Alright, since you're all so energetic, come up and do some practice questions!"

"Zhao Ziliang!"

"Come up here and solve this problem for me!!"

Liu Xiang immediately turned around and wrote a series of questions on the blackboard.

It is a derivative problem of medium difficulty.

"Teacher, it's me!"

Zhao Ziliang almost burst into tears.

He can't even understand the question, how can he answer it?

"Stop talking nonsense and get up here!"

Liu Xiang sneered, giving him the cold shoulder.

Zhao Ziliang had no choice but to slowly walk towards the podium.

My best buddies in the front row couldn't help but laugh.

"Laughing, laughing, still laughing?"

Zhao Ziliang scoffed.

If these people knew that Master Su had already arrived...

She'll definitely yell even louder than him!

At this time.

Zhao Ziliang slowly and reluctantly stood in front of the podium.

He picked up the chalk and stared at the question for a full half minute.

The more I look at it, the more confused I get.

"No, do I know you?"

He didn't write a single word.

"What? You don't know?"

Liu Xiang stood to the side, arms crossed.

"Take your brain out of your heels and use it again!"

Zhao Ziliang's face turned green.

Several students below couldn't help but burst out laughing.

"Ziliang, are you sure you can handle this?"

"Yeah, weren't you just coaxing her quite enthusiastically?"

Zhao Ziliang looked left and right, but couldn't bring himself to do it.

He glanced back at Lin Yue, then at Li Xiaoxiao.

Finally, he simply put the chalk on the podium and gave up entirely.

"Teacher, I really don't know how."

His friends laughed even louder.

"Ugh, I knew you couldn't do it!"

Liu Xiang shook his head and sighed.

"Go down, don't disturb the other students' studying."

"Okay, teacher."

Zhao Ziliang quickly slipped away.

The other students also breathed a sigh of relief.

However, at that moment, Liu Xiang glanced around again and snorted coldly.

"Let's get someone else!"

"Lin Yue, yes, stop looking, it's you, come up here!"

His gaze swept across the classroom.

In the end, it fell on Lin Yue.

Zhao Ziliang was walking down the street when he heard this and stopped in his tracks.

The expression on his face was quite subtle.

The one who laughed the loudest just now was Lin Yue!

Sure enough, the smile didn't stop, it just moved on!

"Hahaha, are you laughing at me?"

Zhao Ziliang was secretly humming with delight.

"Even if you go up there and can't write anything, let's see if you'll still be laughing then!"

He quickly returned to his seat and sat down.

He sat up straight, ready to watch Lin Yue make a fool of herself.

Lin Yue took a deep breath, walked to the podium, picked up the chalk, and glanced at the question.

at this time.

The formulas and ideas that were previously vague in my mind suddenly became clear and distinct.

Lin Yue scratched her head.

"Lin Yue, if you don't know how to do it, hurry up and come down! Don't affect the other students' performance!"

Zhao Ziliang was stirring things up from behind!

But the next second.

He opened his mouth wide.

Lin Yue started writing on the blackboard with chalk almost without pausing.

Find the derivative and rearrange the expression.

Then construct a function, determine its monotonicity, and identify the extreme points.

Every step was clean and efficient, with terrifyingly rigorous logic!

"???"

The expressions on the faces of the surrounding students were all stunned.

Everyone was incredibly surprised.

"Um?"

Liu Xiang's expression changed.

"Holy crap!"

Zhao Ziliang's smile froze on his face.

He couldn't help but swear.

"No, you really know how?"

"..."

Liu Xiang quickly came over.

I carefully reviewed Lin Yue's solution process.

I checked it again.

Every step is correct!

Even the formatting is flawless!

"You...you really did it?"

Liu Xiang's voice carried a hint of disbelief.

He knew all too well what Lin Yue's strength was.

Let alone solving this kind of problem.

It's difficult even to write out the formula!

It's been solved perfectly now?

How is that possible?

"Hmm, it's alright."

Lin Yue nodded, her face expressionless.

Everyone felt that she exuded an air of pretentiousness.

"Holy crap! Lin Yue can even solve this problem?"

"Good heavens!"

"This is terrifying!"

"666 Lin Yue! I underestimated you!"

"We agreed to play the fool and eat feed together! How did you end up eating a tiger?!"

"Is that right!"

"Teacher Liu, I'm reporting this. Lin Yue has definitely been fired!"

"That's right, that's right!"

"....."

The students were all talking about it, unable to believe it.

We all agreed to be academic underachievers together.

And then you just pretended to be something big without saying a word!

What are you doing?!

"Alright, alright, everyone, stop arguing!"

Liu Xiang felt his head buzzing.

He glanced at Lin Yue, then looked at the surprised students around him.

The monk was completely baffled!

What exactly is going on?

Could it be that Lin Yue is hiding her true strength?

Or perhaps she had done this problem before?

But this question.....

Liu Xiang remembers that he made it up on the spot, right?

He turned around and wrote another problem on the blackboard.

This is the final, most challenging question, two levels harder than the previous one.

"Please do this again."

"good!"

Lin Yue was not afraid at all.

She continued to observe the questions.

The feeling of clarity I had just experienced hadn't disappeared; in fact, it was even stronger than before.

Everyone held their breath.

Let's see if she can keep up the act one more time.

Zhao Ziliang's eyes widened, and his hand unconsciously tightened its grip on the pen.

Lin Yue didn't hesitate for long.

He picked up the chalk and started writing.

The steps were still very clean and efficient, and the thought process was also very rigorous and clear.

Three minutes later, the entire room fell silent.

The answer to the entire question appeared completely on the blackboard!

"Wow! Lin Yue's Ren and Tong meridians have really been opened!"

Below the podium.

Li Xiaoxiao and Zhou Yutong whispered to each other.

"That's outrageous!"

"In the past, none of us could understand these kinds of questions!"

"So, can you understand it now?"

"I think I can understand it!"

Li Xiaoxiao nodded seriously.

"Although my problem-solving approach may be slightly different from Lin Yue's, I can still write it myself."

"Me too, I have a few ideas too."

Zhou Yutong's tone was also very confident.

The two of them looked at each other.

It belongs to the category of "the fruit of ignorance under the tree of ignorance," and "you and me under the tree of ignorance."

On the podium.

Liu Xiang's expression was indescribable.

He looked at the blackboard full of problem-solving processes.

silent.

Really.

Having been a math teacher for over twenty years, he knew all too well the difficulty of this problem.

Let alone a student like Lin Yue who is of average or below-average ability.

Even if we take out those top students from the class...

It might not even be possible to make it within three minutes.

"Lin Yue, you."

Liu Xiang hesitated, as if he wanted to say something but then stopped.

"..."

back row.

Zhao Ziliang was completely dumbfounded.

He held his head in his hands.

I was just waiting to see Lin Yue make a fool of herself!

Instead of making a fool of himself, the other person showed off his skills to him!

"How is that possible?"

Zhao Ziliang muttered to himself.

"How did she suddenly become so smart?"

Zhao Ziliang felt abandoned.

"..."

"teacher."

Lin Yue put down the chalk, turned around and looked at all the students in the class.

She was actually a little confused too.

"I don't know how to say it."

Lin Yue thought for a moment.

"After having lunch, I felt my mind became clearer."

"Can you now recall which formulas to use to solve problems you couldn't solve before?"

"A meal?"

Liu Xiang was stunned, almost thinking he had misheard.

"What kind of food?"

"It's the food from that newly opened window in the cafeteria."

"What?"

The classroom erupted in chaos.

"The new one in the cafeteria?"

"Good heavens, could it be that window with the huge queue at noon?!"

"Damn, I wanted to go eat there too, but there were too many people so I didn't get a turn."

"Are you sure? That place is like the Spring Festival travel rush; is it really possible to snag a meal there?"

"You can make yourself smarter by eating it?"

"Really?"

"Is Lin Yue sure she's not joking?"

"....."

Liu Xiang raised his hand to signal everyone to be quiet, but the crowd simply wouldn't quiet down.

Especially after finding out that it was Master Su who opened the window.

The discussion grew even louder.

Zhao Ziliang glanced at Lin Yue on the podium.

Then he looked around at the people.

then.

He slapped his thigh hard, feeling increasingly regretful.

"Dinner, I'll definitely be there early for dinner!"

"This time, nobody's going to take it from me!"

"....."

"Alright, alright!"

Liu Xiang tapped on the podium again.

Finally, we managed to get everyone's attention back!

He stared at the solution on the blackboard, still looking somewhat dazed.

Can a single meal really make someone's brain work better?

How is that possible!

But the answer to this question.

It's clearly written on the blackboard!

Every step was impeccable!

Even a picky old teacher like him couldn't find any flaws!

"Alright, alright, stop fooling around, let's continue with the lesson."

Liu Xiang couldn't understand it and could only shake his head.

His face was expressionless.

But he was already secretly plotting it in his mind.

"I wonder if this meal will make me smarter too? I'll go check it out later!"
