Answering Questions in Chapter 3
"Su Hao!"
The last rays of the setting sun slanted into the classroom, and the air was filled with a slightly murky smell of chalk dust and sweat.
After school, Su Hao, who was frantically stuffing his books into his schoolbag and thinking only of going home, suddenly stopped when he heard this call.
He turned around, flashed a bright smile, and came running over with his short legs.
"Yes, teacher!"
Gu Jin stood beside the podium, looking at the little guy running around on the floor, feeling helpless.
"Do children this age simply lack the genetic option of 'walking properly'? Do they have to run instead?"
This kind of excess energy unique to young children is truly enviable, yet also makes one feel somewhat overwhelmed.
By all accounts, he's just an ordinary country elementary school student...
On Su Hao's youthful face, there was not a trace of the gloomy, lifeless look typical of abused children.
They also lack the repulsive arrogance and slickness characteristic of children who are forced into advanced, cramming-style learning by their parents.
Even in the most basic addition and subtraction lessons, he was just like any other clueless child, enthusiastically raising his hand and doing even the tedious dictation meticulously.
Of course, Gu Jin had no way of knowing that all this obedience...
Actually, it was all thanks to Lin Wan and Su Zhe at home who repeatedly and sternly instructed Su Hao, pulling his ear at every turn.
"You must listen carefully to the teacher in class!"
"Did you bring any difficult books in your bag today?" Gu Jin asked softly.
Upon hearing the teacher's question, Su Hao's clear eyes widened slightly, and he nodded like a chick pecking at rice.
"Hmm. I plan to watch it during break. It's been too hot lately, so nobody goes to the field to play soccer anymore..."
As he spoke, he unconsciously rubbed his two little hands together, his eyes constantly drifting towards the classroom door.
That burning desire to return home was impossible to hide.
"Is there something urgent that you need to rush back?"
Having his thoughts read, Su Hao blushed slightly, a rare occurrence for him, and scratched his head somewhat embarrassedly.
"No...no. It's not like that. Su Hui is waiting for me."
Su Hui is my younger sister, she's super cute!
Besides, Mom needs to wait for me to get back before she can clean and cook dinner. I need to go back and help!
Thinking of the adorable baby she had seen before, gently held in her mother's arms, Gu Jin felt a pang of tenderness in her heart.
That was indeed a lovely baby.
"Ugh! What am I even nervously anticipating?"
Gu Jin shook his head inwardly. The string that had been taut deep in his mind finally relaxed completely, accompanied by a faint sigh.
The Su Hao in front of us is just a kind and simple elementary school student who cares about his mother and misses his younger sister.
Gu Jin decided not to delay any longer and quickly let the well-behaved little guy go home.
"Well...would you mind doing these questions? There aren't many, and you can leave as soon as you're done."
"Really?"
Su Hao, who had apparently thought he would be kept after school for a long time, immediately showed joy on his face upon hearing this.
"Of course! If you find something difficult, just leave it blank, it won't hurt."
This is undoubtedly an extremely intelligent child.
Gu Jin couldn't help but recall those days.
In the top classes of key middle schools, there are a very few one or two prodigies who, from a very young age, casually and self-study middle school mathematics.
One of them, a pervert she once looked up to, is now pursuing a PhD at UCLA, and presumably his hair is almost completely gone by now.
Although Gu Jin didn't believe that Su Hao could reach that superhuman level, if he could really perfectly solve middle school level math problems...
As a teacher, she had to start seriously considering how to provide him with better educational resources.
In the half-second she was pondering, Su Hao had already taken out a cartoon pencil with a little yellow duck on it from the slightly worn pencil case, and started writing the answer directly on his desk.
The first question covers basic knowledge points, specifically ratios.
If 5cm on a map actually represents 2km, then how many kilometers does 8cm represent?
rustling.
That was the soft sound of a pencil tip rubbing against the paper.
"3.2km"
Su Hao's pen fell almost the instant his gaze swept over the question, without even a blink of an eye.
Gu Jin frowned slightly.
Mental arithmetic? Glancing at the answer once, without even thinking, and then writing it down?
She composed herself, her gaze sharpening as she carefully examined Su Hao's profile.
The child's blinking frequency suddenly decreased, and his previously rapid breathing became long and shallow.
His lips were half-closed, slightly pursed inward, and his eyes were fixed on the exam paper, like those of a hawk.
It is clear.
Perhaps because he was so eager to get home, Su Hao went straight into a state of complete focus and full power!
rustling.
The second question is an advanced application of the Pythagorean theorem.
[Given a right triangle with two legs of length 8 cm and 6 cm.]
There is a square with a side length of 8 cm. One side of the square coincides with the right-angled side of a triangle, and the square is located outside the triangle.
Find the distance from the vertex of the square that is not adjacent to the shared side to the midpoint of the hypotenuse of the right triangle.
After reading the question, Su Hao thought for about two seconds and then wrote down the answer.
Gu Jin's pupils suddenly contracted.
She couldn't believe her eyes.
There is no picture for this question!
This is a type of question that requires you to instantly construct a two-dimensional coordinate system in your mind, or an extremely clear spatial geometric projection, in order to find a solution!
He didn't even draw a sketch?!
grunt.
In the quiet classroom, Gu Jin heard herself swallow.
This is a trick question disguised as a calculation problem, but in reality, it tests extreme spatial thinking.
However, Su Hao wrote the answer as if he were looking at "1+1=2", feeling that it was not worth glancing at it again. He then wrote down the answer with a slight flick of his wrist.
"Approximately 11.7 centimeters"
The third question is a quadratic equation in one variable.
[已知一元二次方程x^2+2mx+(2m-1)=0。
If the equation has two distinct real roots, and the absolute value of the difference between the two roots is 2, find the value of the real number m.
This time, Su Hao's pencil didn't pause even for a moment, and he continued to write the answer smoothly.
Gu Jin had completely forgotten to breathe. She stared intently at the piece of paper, feeling as if her worldview was being relentlessly rubbed against the ground by the little yellow duck swaying back and forth.
In an instant, the child came up with the discriminant condition and transformed it into an equation that fit the problem!
Without any pause!
Without the slightest hesitation!
This means he is 100% certain of the answer!
"m=0 or m=2"
"Ugh—!"
Gu Jin subconsciously covered his mouth with both hands, swallowing back the "Holy shit!" that was about to escape his lips.
Is this some kind of ghost story?!
It is not difficult to simply substitute the quadratic formula into the equation to solve it.
However, one must be able to see through the layers of deception in the question, directly grasp its underlying structure, and transform and connect all the conditions...
This terrifying structural thinking ability is absolutely not something a normal human child should have!
Gu Jin felt her heart pounding violently in her chest like a war drum.
Problem-solving speed?
That thing was meaningless at this moment.
What truly terrified her was this talent that could not be taught through "cramming"!
Question 4: Application of trigonometric functions.
The computation is extremely concise, but it requires an extremely ingenious reverse transformation approach.
Su Hao did not simply substitute numerical values into the problem like an ordinary person, nor did he rely on formulas.
At seven years old, an age when even basic arithmetic would be difficult, he had already internalized extremely advanced structural thinking as if it were breathing into his very bones.
The little yellow duck pencil glides across the paper, and another correct answer is revealed in an instant.
Question 5, Calculus.
【Let the function f(x) = x³ − 3ax² + 3a²x − a³ − (1/2) sin2x. Given that f(x) attains an extreme value at x = 0, and the difference between the maximum and minimum values is 1, find the value of a.】
This is a question beyond the syllabus.
The calculation process is short, but the threshold for judging the logic is extremely high.
Su Hao held the comical little yellow duck pencil, glanced at the question casually, and immediately began to calculate.
Gu Jin was practically going crazy!
Her scalp tingled, and goosebumps rose all over her body!
She was incredibly curious about how this child's brain was structured!
A seven-year-old child, faced with such obscure calculus, was not confused at all, and instantly understood the logical flow of the derivative function, the location of the extreme value, and the difference between the extreme values!
The first thing to do is to immediately connect the conditions and the function in your mind.
There wasn't even a single unnecessary step involved.
What does this mean?
This means that Su Hao already possesses perfect logic and genius-level intuition!
A sense of absurdity suddenly surged into Gu Jin's mind.
If I had to describe it, it would be like watching a snotty-nosed elementary school student, holding colorful crayons, casually draw a nuclear submarine construction blueprint on the ground with precision down to the nanometer level.
Within that innocent and naive handwriting lies an extremely rigorous mathematical logic!
This stark contrast carries a terrifying and unsettling sense of unease that sends chills down your spine!
"I'm done, teacher!"
Just as Gu Jin felt her soul was about to leave her body, a clear and childlike voice suddenly pulled her back to reality.
It only took less than two minutes!
Su Hao handed over the thin test paper with both hands.
At this moment, he transformed back into that adorable child whose only thought was to go home, radiating pure innocence.
"Okay...you got them all right. You can go home now."
Because of the extreme shock to his mind, Gu Jin's voice was dry and even had a slight, barely perceptible tremor.
She had a bad feeling, but with only Su Hao wanting to go home on her mind, she didn't notice the collapse of her teacher's worldview.
"Yay! Bye-bye, teacher!"
Su Hao grabbed his schoolbag, waved politely to himself, and then dashed out.
After casually shattering a grown-up math prodigy's understanding of the word "genius," he acted as if nothing had happened, showing absolutely no expectation of being praised.
It was as if he had simply brushed a speck of dust off his clothes.
Gu Jin stood there like a statue, staring blankly at Su Hao's short legs as he ran away.
The wind from outside the corridor swept through the hall, making the curtains flutter.
She was lost in thought.
"What... should I do with you?"
Gu Jin lowered her head, her gaze fixed on the answer sheet for a full ten minutes.
This is a scene that even the most absurd dreams wouldn't dare to depict.
The unfathomable chasm between reality and common sense left her mind a deafening blank.
After a long time, she stretched out her slightly trembling hands and carefully and slowly tucked the answer sheet into a hard-shell folder, so as not to wrinkle even a single corner.
The movements were extremely cautious and devout, as if afraid that even the slightest bit of extra force would crush a priceless treasure.
She's only in first grade.
Without a doubt, this is the age when they are most vulnerable and most easily destroyed by the outside world.
Even if he acts like a god now, he might encounter a mediocre teacher one day and completely lose interest in mathematics.
In this meat grinder-like exam-oriented education system, Gu Jin has seen too many people who were labeled "child prodigies" but ultimately faded into obscurity.
"If he's just an ordinary math prodigy, that's manageable..." Gu Jin muttered to himself.
But Su Hao is not.
Su Hao is an extraordinary individual whose existence is so exceptional that even the conventional term "genius" seems pale and powerless to describe him!
In an instant, Gu Jin hugged her arms tightly, feeling the hairs on the back of her head stand on end.
She suddenly realized a heavy, suffocating sense of fate.
Perhaps, at this very moment, sitting in this dilapidated classroom in a small town...
He happened to be standing at a crossroads that could directly influence the course of history and determine the fate of a future great man who would be remembered in history!
hiss!
She took a deep breath, and a sense of reality finally began to return to her body.
The fingertips resting on the table were still trembling slightly, uncontrollably.
Gu Jin sat there alone for a long time, mentally going through all the possible solutions he could come up with.
But no path made her feel completely safe.
Why?
The reason is obvious.
Because she herself was never a genius.
How can a sparrow know the flight path of a swan?
She simply lacks the foundation and vision to judge which path is the optimal solution.
"It's decided."
Since it's a matter for geniuses, then we should ask geniuses.
Or, ask someone who once stood at a similar height and looked down upon all living beings.
This burden, which could potentially determine the course of human history, is far too heavy for a mere mortal to bear.
Beep, beep, beep...
A long waiting tone came from the phone.
A voice finally came from the other end of the phone just as the ringing was about to end due to timeout.
What brings you here? You actually... called me on your own initiative.
The owner of the voice seemed to be trying his best to cover it up, but his tone still revealed an extremely strong sense of embarrassment and discomfort.
There's something I want to ask you.
Gu Jin didn't waste any words and went straight to the point.
A suffocatingly long silence fell on the other side.
Then, accompanied by a sigh that seemed to be a helpless resignation to fate, the voice replied:
【Hold on……】
......
"drop--"
A first-tier city thousands of miles away.
Shen Yuxuan quickly stopped the expensive video recorder in front of him.
The blackboard behind him was densely covered with charts and formulas that would make an ordinary person dizzy at a glance.
He frowned.
My ex-girlfriend, whom I haven't contacted in ages, suddenly called me today. What's gotten into her?
Hearing the other person's unusually serious tone say "I have something to ask," Shen Yuxuan casually ripped off his tie, strode out of the recording studio, opened the freezer in the lounge, and took out a can of black coffee.
Click—pull the ring open.
"Speak, what is it?" He tilted his head back and took a swig.
Among my students, there emerged an extremely brilliant genius.
Upon hearing this, Shen Yuxuan scoffed.
"What kind of genius nonsense is this? We haven't spoken on the phone in years, and you called me specifically just to say this?"
I'm tired of hearing it.
He was sick of hearing such cheap vocabulary.
Back when he was selected for the national training team, he received a plethora of praise.
But after witnessing those real monsters in that world, he realized that none of it mattered.
The true title of "genius" belongs only to a very few people chosen by the gods.
The geniuses in the eyes of ordinary people are not even worthy of carrying his shoes.
I know what you're thinking, but this time it's really different. You have no idea, this child...
However, Gu Jin didn't finish her sentence.
"That's enough! If you don't have something serious to say, I'm hanging up!"
A suffocating silence fell over the other end of the receiver.
A pang of regret welled up in Shen Yuxuan's heart.
He gritted his teeth inwardly, wondering if he had been too rude.
They were people I once confided in...
But why did that woman have to be so reckless as to poke at his sore spot?
She knew better than anyone that the thing he hated most in his life was hearing such cheap praise!
Just as Shen Yuxuan was frowning, his mind racing as he tried to figure out how to back down gracefully...
[Petty...]
"What did you say?"
I'm telling you, you're such a petty person!
"Are you really looking for death?" Shen Yuxuan's temple veins bulged instantly.
How long are you planning to hold grudges about those petty things?
The more I listened, the angrier I became.
Everyone has wounds that cannot be touched.
And this woman is now dancing on his wound in high heels!
"What grudge do I hold?! Go ask around, among all the classmates in our graduating class, is there anyone who earns more than me?!"
Shen Yuxuan laughed in anger.
Last year, the taxes paid by his studio alone amounted to ten million.
He is now a top tutor in the entire education and training industry, revered as a god by all parents who hope their children will succeed and high school students preparing for the college entrance examination!
He is a math tutoring god with top-notch academic qualifications and competition experience!
Who gave her the right to mock him, Shen Yuxuan?!
However, Gu Jin's next casual remark was like a bucket of ice water, extinguishing all his arrogance.
[Since you, a renowned teacher, are so proud of yourself, why don't you even dare to attend a class reunion?]
"...That's all because of you. Don't you feel awkward seeing your ex-boyfriend?"
[Tch, stop talking nonsense.]
"Alright, alright, I'll listen to you. Say it again. What exactly happened to that student of yours?"
On the other end of the phone, Gu Jin let out a sigh of relief.
Then, her voice became extremely serious:
[A first-grade elementary school student can perfectly understand and solve high school competition problems and calculus problems.]
Upon hearing this, Shen Yuxuan's previously relaxed expression immediately darkened again, and a hint of mockery flashed in his eyes.
"You're still hanging around in Haidian District? Those parents are really ruthless. What kind of life are they driving a seven or eight-year-old to...?"
He'd seen this kind of trick too many times.
Every year, several of these "assembly-line prodigies" emerge, whose growth is forced and accelerated.
A little bit of good genes combined with that inhumane and inhumane cramming of advanced problems can often give birth to this kind of deformed child who can solve calculus.
Shen Yuxuan was willing to bet that in a few years, most of these poor puppets would reveal their true colors, realize that they were just ordinary people, and then go and get into a 985 or 211 university.
If parents still can't shake off that morbid fantasy, the next step will probably be to send them to a variety show like "The Brain" to show their faces and earn some tears with sentimental music.
That's ridiculous.
Who would buy that kind of thing?
No. I'm not in Haidian anymore; I've gone back to my hometown.
"In Daji County?"
Shen Yuxuan was stunned for a moment.
When they were dating, he once accompanied Gu Jin back to her obscure hometown.
【Um. 】
"How could children in such impoverished, remote areas, where educational resources are so scarce, possibly solve problems at this level?"
Don't even mention you, I couldn't believe it at first either.
I specifically called the child's mother to the school yesterday afternoon to talk to her.
Forget about tutoring classes, no one in their family has ever taught them.
All of this he achieved through reading, self-study, and self-realization!
Are you sure your parents aren't lying to you?
Do you think I, Gu Jin, am the kind of idiot who can be easily fooled by women from rural towns?
I've checked it repeatedly!
Yu Xuan, can you give me some advice?
When I saw him write down the answers with a cartoon pencil today, my hands were shaking.
I don't know what to do with this child.
Should I help him contact the University of Science and Technology of China's gifted youth program?
Or perhaps you could inquire about skipping a grade?
I even took out my phone just now, thinking of calling our former homeroom teacher...
Gu Jin's urgent words were abruptly interrupted by Shen Yuxuan.
"Give me a break! By doing that, you're ruining that child with your own hands!"
It will only taint parents with an extremely foul stench of vanity and ostentation.
That little brat who doesn't even understand how big the world is will also get carried away, turning his meager cleverness into an arrogant belief that he's the best in the world!
"So what do you suggest we do? This is truly the first time in my life I've ever seen a child like this."
"That's really rare in the country."
Shen Yuxuan's gaze became somewhat unfocused.
"But occasionally, a few will still pop up abroad."
Those... monsters who never play by the rules.
As if recalling some extremely tragic and unpleasant memory buried deep within his mind, Shen Yuxuan's originally handsome face was now twisted into an extremely ugly shape.
Am I just supposed to stand by and watch, and abandon everything?
"Of course not."
Shen Yuxuan took a deep breath, his eyes sharpening once more.
"Assuming everything you're saying is true."
So, do you know what a true genius like that little guy needs most to survive in this mundane world?
Yes, yes, yes. Because I'm not a genius, I know nothing about it.
Shen Yuxuan completely ignored Gu Jin's sarcastic tone this time.
His tone was more serious than ever before, and he gave that cold and cruel answer.
"Overwhelming results."
What?
This completely unexpected answer left Gu Jin speechless on the other end of the phone, leaving her utterly astonished.
