Chapter 2 What's the use of being good-looking? A useless person who can't even touch a si
Su Qingwan composed herself and put on a sweet smile: "Okay."
Classroom of Senior Three (7)
Lin Yu returned to his seat.
My deskmate is a fat guy, and he's taking a nap with his head on the table.
Lin Yu took out a thick notebook from the drawer.
The cover reads "Qingwan's Exclusive Score-Boosting Notes".
It contains the high school exam strategies he summarized as a scholar in his previous life. As long as you follow this logic, even a fool can improve his score.
Lin Yu did not hesitate at all.
"Sizzle."
The notebook was torn in two.
Tear it again.
A few dozen seconds later, a priceless notebook was reduced to scraps of paper, which Lin Yu threw into the trash can at his feet.
After doing all this, Lin Yu pulled a blank sheet of draft paper out of his bag.
He drew a coordinate system on the paper with a pen.
Then, a string of formula code was written down.
He began to memorize the underlying logic tree of the national exam question outlines from previous years.
Step 1: Decipher the psychological threshold of the question setter.
Step 2: Calculate the error tolerance rate for the paper-making process.
Step 3: Precisely control the final score of each subject.
"The trial period for pretending to be a bad student has expired."
Lin Yu leaned back in his chair, his slender fingers twirling the pen.
"Next, let's begin the real numbers game."
The school bell rang.
Class teacher Wang Tuzi walked onto the podium with his lesson plan in hand.
He slammed his lesson plan onto the lectern.
The entire class fell silent instantly.
Wang the Bald's gaze swept across the entire room, finally fixing on Lin Yu in the back row of the classroom.
"I'm sure everyone has seen the results of this diagnostic test."
Wang the Bald tapped the blackboard, "Some students, like Li Hao and Su Qingwan, perform consistently and are the pride of our class. But that doesn't change the fact that our class average is being severely dragged down by certain individuals!"
Baldy Wang pointed his finger directly at Lin Yu.
"Lin Yu! Stand up!"
Lin Yu stopped twirling his pen and stood up. His school uniform remained open, and his expression was completely expressionless.
"A total score of 520. Fifth from the bottom in the class. Ranked outside the top 300 in the entire school!"
Baldy Wang slammed his fist on the lectern, yelling, "Is your brain filled with water? With grades like yours, you still have the nerve to run to other classes every day? Will it give you extra points on the college entrance exam?"
All eyes in the class were on Lin Yu.
Mockery, sympathy, and schadenfreude were intertwined.
Everyone understood that Baldy Wang was mocking Lin Yu for pursuing the school beauty.
"Teacher Wang."
Lin Yu spoke. His voice wasn't loud, but it was extremely clear.
"The test paper for this diagnostic test was completely illogical, and it wasn't challenging to get all the questions right. So I deliberately left some questions blank."
The whole class erupted in uproar.
The fat classmate tugged at Lin Yu's trouser leg in alarm and whispered, "Brother Yu, are you crazy? Talking back to the bald guy?"
Wang the Bald was so angry he laughed.
"Fine, fine. You deliberately left some questions blank. Who do you think you are? An expert from the national exam question-setting team?"
Wang the Bald turned around, grabbed a piece of chalk, and quickly copied down an extremely complex and challenging math problem on the blackboard.
That was an extra question that no one in the entire school could answer during this diagnostic test.
"Since you're so capable..."
Baldy Wang threw half a piece of chalk at Lin Yu. "Come up here! Solve this problem. If you can't, you'll be standing in my math classes from now on!"
The chalk traced a parabola in the air.
Lin Yu raised his right hand and steadily caught the flying chalk between two fingers.
He looked up at the question on the blackboard.
A comprehensive problem involving finding the derivatives of extrema of multiple variables.
In the eyes of ordinary high school students, this is an insurmountable barrier of knowledge.
But in Lin Yu's eyes...
This doesn't even qualify for the basic prerequisites of calculus.
Lin Yu pushed back his chair and strode toward the podium.
The afternoon sunlight pierced through the glass of the corridor, cutting obliquely into the passageway of Class 7.
Lin Yu held the broken piece of chalk, pushed back his chair, and walked from the last row to the front.
He passed by Su Qingwan's seat, bringing with him a very faint scent of mint soap. Su Qingwan instinctively looked up, her gaze fixed on Lin Yu, and she suddenly froze.
Not only her, but several other girls in the class who were originally waiting to see her make a fool of herself also held their breath for a moment.
Lin Yu used to habitually hunch his back a little. That was a habit he developed to accommodate Su Qingwan's height of 1.65 meters, making it easier for him to bend down and explain problems to her.
His hair was always messy, making him look listless, and he exuded a sense of inferiority due to a people-pleasing personality.
But now, he stood up straight.
His height of 1.85 meters was fully revealed. His back was straight, and the zipper of his large school uniform was completely open, revealing the pure white T-shirt underneath that outlined the boy's slender yet powerful muscle lines.
The wisps of hair on her forehead were lifted by the autumn wind outside the window, revealing a pair of narrow eyes that showed no emotion whatsoever.
His pace was neither hurried nor slow, exuding an air of nonchalance as if he didn't care about the whole world.
From a timid, submissive underachiever to a cool, aloof, and handsome guy with an aura of confidence, this contrast instantly captivated the entire class.
Su Qingwan gripped her pen tightly. She suddenly felt that Lin Yu was utterly unfamiliar. So unfamiliar that a strange unease rose within her.
"What's the use of being good-looking? You're a useless piece of trash who can't even get close to the first-tier university entrance exam."
Li Hao sat in the first row, twirling the pen in his hand, and sneered in a low voice.
Lin Yu ignored the gazes around him. He walked straight to the front of the podium and stood there.
On the blackboard were Wang the Bald's flamboyant handwriting:
Given the function f(x, y) = x² + y² - 2x - 4y + 5, and satisfying the condition x² + y² ≤ 4, find the maximum and minimum values of the function f(x, y), and derive their geometric meaning.
This is a classic multivariable conditional extremum problem. According to the high school mathematics syllabus, solving this problem requires using trigonometric substitution, letting x = 2cosθ and y = 2sinθ, then substituting them into the function expression, simplifying using the auxiliary angle formula, and then combining this with the boundedness of trigonometric functions for a lengthy and tedious classification discussion that takes up an entire page.
Wang the Bald stood to the side, arms crossed, a stern smirk on his lips. He wanted to use this question to publicly strip away Lin Yu's pride, to make this arrogant and ignorant student understand the price of arguing with a teacher.
Did you understand the question?
Baldy Wang tapped on the lectern, "If you don't understand, get down and stand there."
Lin Yu didn't speak. He didn't even pick up the draft paper on the lectern.
He simply raised his right hand.
"Yes."
The chalk landed on the blackboard with a crisp, clear sound.
Immediately afterwards, the chalk moved rapidly across the blackboard. The scratching sound was continuous and rhythmic, without the slightest pause or hesitation.
The students below, who were expecting a good show, widened their eyes in surprise. They noticed that Lin Yu's handwriting had changed.
No longer the scribbled mess of old notebooks, done to save time, but the sharp, elegant strokes of the "Slender Gold" calligraphy style. Every number, every letter exudes absolute confidence.
