I control the AI ​​empire thanks to the geniuses in my group.

Early the next morning.

The alarm clock rang, and Su Xing jumped out of bed.

She's doomed. She fell asleep after watching for only ten minutes last night. Did her brother find out?

If someone asks me about this, where will I put my face?

While washing up, Mom asked, "Xingxing, how did your reading go last night? Did you understand your brother's textbook?"

With a toothbrush in his mouth, Su Xing mumbled, "It's...it's alright."

"How much have you watched?"

"So many!" Su Xing exclaimed, swatting away the foam. "I read so many pages! It's just too late, so I'm going to sleep now!"

"Oh? You've read quite a few pages?" Su Zhou, carrying a bowl, passed by her from behind and casually asked, "What section of the chapter on rational numbers are you on?"

Su Xing suddenly got stuck.

"The...the..."

She had no idea where she was on the page, because she had already given up on the third page.

Su Zhou didn't press further, but simply smiled and placed a fried egg into her sister's bowl.

"It's okay, take your time. It's normal not to understand it yet; you're only in fifth grade."

Su Xing walked to the dining table, her ears as red as boiled shrimp.

Mom tried to smooth things over, saying, "Xingxing is still young, no rush, read as many pages as he can."

Dad also brought over a glass of soy milk and chimed in, "That's right, that's right. Your brother's situation is special, we shouldn't compare ourselves to him."

Su Xing took a big bite of the egg, secretly vowing revenge in her heart.

When she gets back tonight, she absolutely has to see page ten!

No, page 20!

She, Su Xing, the fifth-grade class monitor and a perfect scorer in Chinese, could not possibly be defeated by a lousy math book!

At 7:30 a.m., Su Zhou first took Su Xing to the entrance of the primary school.

The little girl skipped and hopped into the school gate with her schoolbag on her back. After taking a few steps, she turned back and waved to Su Zhou.

"Brother, study hard in high school and don't let anyone bully you!"

"Does your brother seem like the kind of person who would be bullied?"

"That's right!" Su Xing grinned and turned to run away.

Su Zhou watched her go inside, then turned and walked towards the school.

At 7:50, he appeared on time at the door of Teacher Zhou's office.

Teacher Zhou was preparing her lesson plan when she saw him raise his head and look her up and down.

"You're here quite early. Have you read your book yet?"

"I've seen it."

"How much did you watch?"

"I've finished watching them all."

Teacher Zhou paused for a moment.

Have you finished watching it?

He gave me eight books yesterday, including math, physics, and chemistry, and this kid read them all in one night.

Haha, kids these days really know how to brag.

Forget it, I won't call him out on it. Once he sees how capable the other classmates are, he probably won't be so arrogant anymore.

"Come on, I'll take you to your class."

Grade 3 (1) Class.

During the morning self-study period, a tense learning atmosphere permeated the classroom.

Forty-two desks were neatly arranged, each piled high with supplementary teaching materials. Some students were memorizing English words, some were doing math problems, and some were copying yesterday's notes.

This is the top class in the entire grade; everyone sitting here is a formidable individual.

The door was pushed open.

Teacher Zhou walked in front, and Su Zhou followed behind.

All eyes in the classroom turned upwards.

A boy wearing a junior high school uniform walked in slowly, his backpack strap slung over his shoulder.

"A new classmate?"

"A junior high school uniform? You've come to the wrong classroom, haven't you?"

"Who is this?"

Whispering conversations spread through the classroom.

But two people reacted completely differently.

In the third row by the window, Zhao Zixuan was playing with a pen when he saw the figure at the door. The pen flew out and bounced onto the back of the head of the person in front of him.

"Holy crap?!"

In the middle of the fourth row, Song Yuhan's eyes were wide open.

The two looked at each other, their eyes displaying the same expression.

It's a ghost!

Yesterday, the two of them were at Coach Zhang Hengyuan's testing site.

They watched as this seventh-grade boy completed six competition questions in less than an hour, and was then handpicked by Coach Zhang on the spot.

They remember it clearly; their feelings at the time were a mixture of admiration and resentment.

After they got back, the two encouraged each other, saying that losing to Su Zhou was only temporary, and maybe they would surpass him next time they met Su Zhou?

Only one day had passed.

one day!

This person just sat down in their classroom!

Zhao Zixuan and Song Yuhan looked at each other, unsure whether to applaud or cry.

Teacher Zhou stood on the podium and tapped on the table.

"Quiet."

The buzzing in the classroom stopped.

"Let me introduce you all. This is Su Zhou. He was a first-year student at our school. Although he is relatively young, he has excellent grades. He will be joining our class starting today."

That's all.

Teacher Zhou thought about it last night. Su Zhou is too boastful, so let him prove himself.

"Su Zhou, sit in the third row, the empty seat next to Zhao Zixuan."

Su Zhou nodded and walked over amidst the surprised gazes of the other students.

Zhao Zixuan watched him walk over, his feelings were very complicated.

Yesterday, I wanted to surpass someone; today, they're my deskmate.

It was so unexpected.

"Hello." Su Zhou sat down and nodded to him.

"Hello." Zhao Zixuan forced a smile, his mind racing.

Calm down, calm down.

Although Su Zhou is good at math competitions, he jumped from the first year of junior high school, so he definitely can't keep up in other subjects. The difficulty of high school physics, chemistry, and English is completely different from that of the first year of junior high school, so it's impossible for him to excel in all of them.

Thinking about it this way, Zhao Zixuan felt much better.

Su Zhou definitely has weaknesses, so I can take the opportunity to tutor him. Before long, we'll get along well and be able to connect with him.

The surrounding classmates didn't know the details of Su Zhou skipping a grade, but when they discovered that a junior high student had become their classmate, the desire to secretly compete with him arose.

After all, a high school student's self-esteem cannot be easily crushed by a middle school student.

The first lesson was physics.

My first-year high school physics teacher's surname is Chen. He is in his early forties and his teaching style is fast-paced. He likes to ask random questions in class.

Today we're talking about Newton's Third Law.

"Last lesson we learned Newton's second law, F equals ma, which is the bridge between force and motion. Today we will look at the third law, action and reaction forces."

Teacher Chen drew a diagram on the blackboard, with a pair of arrows pointing in opposite directions between the two objects.

"What are the characteristics of this force? Students, please look at the description in the textbook first, and then I will ask you questions."

The sound of pages turning filled the air.

Zhao Zixuan glanced at Su Zhou beside him and found that he hadn't even opened the book.

It wasn't that he didn't bring his books; he had brought the textbooks that Teacher Zhou had given him last night. He just sat there, looking at the diagrams on the blackboard, squinting slightly, and then... wrote something in his notebook.

Zhao Zixuan peeked out secretly.

The notebook didn't contain textbook content, but rather a mechanics model that he didn't quite understand.

What is that?

"Okay, I'll ask my question now."

Teacher Chen glanced around the classroom: "There's a classic question: since action and reaction forces are equal in magnitude and opposite in direction, why does a cart move forward when a horse pulls it? Does the force of the horse pulling the cart cancel out the force of the cart pulling the horse?"

The classroom fell silent.

This is an old question, but few people can really explain it clearly.

Teacher Chen was about to call roll when a hand went up.

The third row, the new boy in the junior high school uniform.

Teacher Chen raised an eyebrow: "You are... Su Zhou? A new student? Tell me about it."

Su Zhou stood up.

"They do not cancel each other out, because the two forces act on different objects. The force of the horse pulling the carriage acts on the carriage, and the force of the carriage pulling the horse acts on the horse. They do not constitute the force analysis of the same object, so they cannot be directly added together to cancel each other out."

"Yes, this analysis is correct, but not comprehensive."

Su Zhou continued, "The fundamental reason why the car can move forward is that the static friction force of the horse's hooves on the ground is greater than the rolling friction force on the wheels. Newton's third law describes the symmetry of forces, but the direction of the system's motion depends on the resultant force of each object. If we analyze the two objects separately and list their respective force equations, the car's acceleration will be clear at a glance."

The classroom fell silent for a moment.

Teacher Chen's eyes lit up.

"Sit down." He nodded. "That was an excellent answer. You not only answered what it was, but also why."

Then he glanced at the whole class and added, "Some students have been studying for half a month and are still struggling with whether the forces cancel each other out. New students can break down the force analysis to the individual unit level on their first day. They should reflect on this carefully."

Zhao Zixuan sat next to Su Zhou, and the pen in his hand kept spinning until it stopped.

Not right.

Something is very wrong.

This answer is not at the level of someone who has just read the textbook once.

Especially the last sentence, which analyzes the two objects separately and lists their respective force equations, is the core way of thinking in mechanical analysis. Many people have to do dozens of problems to truly establish this, but he can just spout it out.

Zhao Zixuan had no idea that Su Zhou had worked with Newton in the 17th century, and that Newton had personally taught him force analysis, so Su Zhou was naturally able to grasp this way of thinking.

In the following lessons, Zhao Zixuan's mentality was repeatedly tested.

In chemistry class, the teacher was explaining ionic reaction equations. Su Zhou was the first to hand in his paper during the class exercise, and he got them all right.

In English class, Ms. Qi seemed to prefer Su Zhou, and kept asking him to lead the reading.

More importantly, Su Zhou's English pronunciation seems to be even more beautiful and standard than Teacher Qi's.

By the end of the English class, he had only one thought in his mind.

This person is such a pervert!

How come I seem to know everything?

During break time.

Zhao Zixuan lay slumped on the table, staring blankly at the ceiling, questioning the meaning of life.

Beside him, Su Zhou was flipping through a book.

It's not a textbook.

Zhao Zixuan turned his head and saw the words "High School Mathematics Competition Training Course" on the cover.

and many more.

Isn't this his book?

He looked down at his desktop and, sure enough, his competition tutorial was gone.

"When did you take it?"

"Just now," Su Zhou said without looking up, "this book fell on the floor. I found it interesting, so I flipped through it. You don't mind, do you?"

Zhao Zixuan wasn't that petty. He thought to himself, "They helped me pick up the books, so what's wrong with taking a look?"

And to be honest, Zhao Zixuan was a little proud of himself. He had already read half of the book, which was a very difficult competition preparation textbook on the market. He had to work through many of the problems by himself.

Although Su Zhou has a strong competitive instinct, it's impossible for him to understand such a systematic teaching material after just a couple of glances.

When Su Zhou has questions, he can ask him, and then he can naturally demonstrate his abilities.

Thinking of this, Zhao Zixuan felt much better and settled down to rest.

Lunch break.

Most people were asleep at their desks, leaving only a few desk lamps and the occasional rustling of papers turning in the classroom.

Half-asleep, Zhao Zixuan glanced at Su Zhou.

He was still reading that book, "High School Mathematics Competition Preparation Course"!

Zhao Zixuan was a little curious about which page he was on and wanted to look up, but he was too sleepy, so he turned over and lay back down.

When lunch break ended, Zhao Zixuan groggily looked up, and Su Zhou pushed the competition tutorial book towards him.

"Here you go, I've finished reading it."

Zhao Zixuan blinked.

"……What?"

"I've finished reading it, here you go."

Zhao Zixuan glanced at the book, then at Su Zhou, thinking he was having a nightmare!

"You said you finished reading it? The whole book?"

"Um."

"This book has over three hundred pages."

"Yes, 328 pages."

Zhao Zixuan paused for two seconds, then gave what he considered the most reasonable assessment: "You're bragging."

Su Zhou didn't argue, but leaned back in his chair and casually said, "The problem about integer partitioning in Chapter 7, Section 3, the book uses the generating function method, right?"

Zhao Zixuan was taken aback.

He subconsciously flipped to Chapter 7, Section 3, which indeed showed integer partitioning and the use of a generating function.

He had just finished reading this chapter last week, and it left a deep impression on him.

"The solution in the book is fine, but it's not elegant enough."

pretty?

Why bother with making math olympiad problems pretty?

Zhao Zixuan secretly rolled his eyes.

Su Zhou said, "Although generating functions can be used in this problem, the expansion process is too cumbersome. It requires handling several layers of coefficient extraction, which consumes too much time in the actual exam."

Zhao Zixuan became serious.

He felt the process was too long when he did the problem, but he thought it was because his calculation skills were not good enough, and he did not think that it was a problem with the method itself.

"Do you have a better idea?" Zhao Zixuan asked anxiously.
