Chapter 154: Chapter 154

Shen You’an adjusted the glasses on her nose bridge and calmly said, "When constructing the concept of derivatives, there is one very crucial question."

Shen You’an picked up a portable hard drive from the podium and showed it to the class. "Why do two hard drives with identical volume have different storage capacities?"

Someone answered, "Because the material is different."

"If a hard drive is given, how can you maximize its capacity?"

This stumped everyone.

"The capacity of a hard drive depends on tracks and sectors. The density and width of the tracks directly affect this. Efficient track width is a decisive factor in determining the storage capacity of a hard drive. Therefore, we can establish a limit model to calculate the maximum hard drive capacity. As one of you just mentioned, your focus was either on volume or material. Most often, people approach such problems from surface-level observations. But if you can rise beyond these observations and discern the mechanism behind the hard drive’s capacity formation—seeing the essence through the phenomenon—that is the foundational way of mathematical modeling."

"In constructing the concept of derivatives, extreme values are very important, and extreme values themselves are tightly linked to mathematical modeling."

Shen You’an finished speaking, looked towards Chen Zhou at the side, and nodded slightly. "I’m done."

With that said, she stepped down from the podium and headed back to her seat.

The entire class fell silent instantly.

Even Chen Zhou was momentarily speechless.

The presence or absence of mathematical modeling awareness often determines the level at which problems are solved, and it reflects a student’s true mathematical competency.

While other students were still in a hazy, unclear stage, only Shen You’an had grasped the key to the matter, using critical factors and their relationships to construct mathematical models—thus completing the analysis and solving of the problem.

This isn’t just advanced knowledge; it’s overwhelming dominance.

Shen You’an—was she really only fourteen? Such depth of thought—at fourteen, he was still in the seedling phase.

Under the gaze of countless admiring eyes, Shen You’an returned to her seat, propped her head with one hand, stretched a bit, and found herself drenched in sweat.

"Oh my god, has Shen You’an already studied advanced college-level calculus? Is she secretly a master of time management?"

Qin Xiangge tightened her grip on the pen as she listened to her deskmate’s exaggerated exclamation.

"Maybe her day has forty-eight hours instead of twenty-four."

The deskmate murmured, "I feel like her explanation was clearer and easier to understand compared to Mr. Chen’s. Should I ask her for help after class? I don’t think she’d refuse me, right?"

Chen Zhou tapped the podium. "Everyone, focus! Let’s continue with the lecture."

After that, if Shen You’an decided to nap again, no one dared to gossip anymore.

Before lunchtime, the events during Shen You’an’s math class had already spread rapidly across all the freshman classes.

Everyone unanimously marveled: this person is the real deal.

"Hey, Shen You’an, what did you do last night? Why are you sleeping all the time today?"

During lunch break, Gao Yuyue tapped on Shen You’an’s desk.

Shen You’an lay motionless.

Gao Yuyue grew fed up and stormed off in annoyance.

After napping, Shen You’an woke up and regained some energy.

Lifting her head, she saw a sandwich and a cup of fruit tea placed on her desk.

Shen You’an scanned the surroundings. It was lunchtime, and only a few students were scattered throughout the classroom.

Her gaze landed on a slender figure sitting diagonally in front of her.

She recalled the boy’s low, gentle reminder earlier and instinctively frowned.

She had never interacted with this so-called God Liu before, and he was an extremely aloof individual. Why would he bother going out of his way to remind her about formulas?

Shen You’an pursed her lips and shifted her gaze to the sandwich.

She truly had no appetite.

And food with unknown origins—she wouldn’t touch it.

Just then, the boy turned his head and glanced at her.

Shen You’an showed no awkwardness at being caught in the act. "Thanks for the reminder."

Liu Runxi replied indifferently, "I was being unnecessary."

Even without the reminder, she would answer beautifully.

She was clever by nature, wasn’t she?

Thinking of this, a faint smile tugged at the boy’s lips—a fleeting moment that quickly vanished, replaced again by his usual aloofness.

"The sandwich and fruit tea are mine. I’m not hungry, so you have them."

With that, he turned his head away, leaving only his cold back to Shen You’an.

Shen You’an furrowed her brow. This guy was really peculiar.

She wasn’t hungry but was slightly thirsty.

Shen You’an picked up the cup of fruit tea. The warmth of the cup startled her.

She inserted the straw and took a sip.

Shen You’an’s eyes flickered slightly.

It was brown sugar fruit tea.

She instinctively looked again at the boy’s back.

Could he possibly think she was on her cycle?

At this thought, Shen You’an suddenly started coughing, violently choking.

The boy’s back remained motionless.

Unbeknownst to Shen You’an, the angle she couldn’t see revealed the boy gripping his pen tightly, his knuckles white from the force. The veins on his hand bulged vividly.

Still, he did not turn his head.

Close to noon, Jiang Shengyao sauntered into the school gates.

The gatekeeper naturally didn’t dare stop him and greeted him with a smile, ushering him inside.

Especially with this young master’s rebellious demeanor, who would dare cross him?

"Mr. Jiang, you’re never late. Be honest, where did you wander off to last night? Take us along next time, will you?"

"Get lost—all of you!" Jiang Shengyao snarled, his tone furious.

The group exchanged looks and scrambled away hastily.

No one messed with Jiang Shengyao when he was in his rage-filled mode.

Jiang Shengyao ambled to the door of Class A and peeked into the classroom.

In the corner, the girl was still napping on her desk.

Jiang Shengyao let out a cold snort.

Always sleeping—how on earth did she get first place?

As Jiang Shengyao hesitated, a soft and warm voice sounded behind him.

"Ayao, are you looking for me?"

Jiang Shengyao turned his head and met Qin Xiangge’s smiling, beautiful eyes.

Passing students from Class A tossed eight curious glances toward the two.

In fact, it was a widely accepted secret that these two were considered a pair within the school.

Seeing Qin Xiangge reminded Jiang Shengyao of Lii Yinyin’s tearful, pitiful face, and his stomach churned with nausea.

"Lii Yinyin isn’t worthy of being your friend. Don’t concern yourself with her matters anymore."

After delivering this remark, Jiang Shengyao moved to leave.

Qin Xiangge froze for a moment and instinctively grabbed his arm.

"Ayao, what’s wrong? Yinyin is very pitiful—this is her entire life..."

Jiang Shengyao irritably shrugged off her hand and said coldly, "Pitiful? What a joke. Helping her makes me the biggest fool alive. I advise you to keep your distance from her. And she doesn’t have the face to come back to school either."

"Ayao, what happened? Why did you change so suddenly?"

Qin Xiangge was confused. Just a few days ago, Jiang Shengyao had been adamant about helping her. Why the sudden shift?

If that’s the case, doesn’t it mean Shen You’an is fine now?

Jiang Shengyao, annoyed, didn’t want to explain further. His anger even spilled over toward Qin Xiangge.

"Forget it—you’re better off not knowing. Just remember my words. I’m leaving now."

Leaving Qin Xiangge standing there, Jiang Shengyao walked away briskly.

Qin Xiangge was left puzzling, then took out her phone to call Lii Yinyin.

The phone was powered off.

For some reason, a sense of foreboding struck Qin Xiangge in her heart.

Accompanied by a girl’s brash tone, Qin Xiangge was suddenly bumped off-balance, staggering. Before she could fall, a pair of arms appeared and steadied her, sparing her from a disaster.

"Careful," a gentle voice sounded above her.

Qin Xiangge stared blankly at the elegant and refined face in front of her. "Gu... Gu classmate."

Gao Yuyue rolled her eyes and sneered. "What a cliché scenario, huh?"
