Chapter 293: Chapter 293: Slapping Fu Chen’s Face, Sending Him Offline! (1)
Lu Sheng’s proof process, casually written on the blackboard, directly shocked everyone else in the class, including Zhou Wu.
This method was indeed much simpler and more sophisticated than the one provided in the reference answer.
Even compared with it, the whole page of proof process in the reference answer seemed superfluous.
The question Lu Sheng asked, although in a cool and indifferent tone, carried the oppressive aura of a top-tier student.
It was as if she was saying, "Do you think I, who can think of a simpler solution, would be dumb enough to spend twice the time writing so much?"
But it wasn’t over yet.
The other students below the stage didn’t expect the girl on the stage to continue, "But in fact, I thought of an even simpler proof method than trigonometric substitution during the exam."
Saying this, she picked up the chalk without caring about people’s reactions, turned around, and started writing and drawing on the blackboard again.
This time, the proof process she wrote was only seven or eight lines long, plus a graph of a function.
Despite the few words and a straightforward graph.
But if they could somehow understand the trigonometric substitution method with some effort, this time, they couldn’t comprehend the proof process at all.
After Lu Sheng finished, she put the chalk on the lecturer’s desk and looked up at everyone.
"Using the extremum of multivariate functions to prove this question is a bit like using a sledgehammer to crack a nut."
"This method is the simplest in terms of the proof process, but the hardest to understand. I was afraid that the examiner might not understand it at a glance, so I didn’t write it like this at the time."
——I was afraid that the examiner might not understand it.
Could she possibly be more arrogant?
But at that moment, no one was contradicting Lu Sheng, as they realized that not only did they not understand, but Zhou Wu standing beside the lectern also showed a puzzled look.
Probably thinking the same thing.
Holy crap, besides that method, there’s also this way of solving it?
Using the extremum of multivariate functions... Oh, that’s how it is!
A few seconds later, Zhou Wu, who was staring at the blackboard, couldn’t help nodding, with an expression like he’d learned something new as well.
Whether it was Lu Sheng being able to easily write out the complete process, or her calm and composed demeanor while explaining, it was clear evidence that these ideas were all in her head.
If she hadn’t really thought about it before and had simply copied the answers during the exam, how could she now glance at the question and directly write two advanced solutions they had never even thought of?
However, before Zhou Wu could speak, Fu Chen saw the rest of the class beginning to study Lu Sheng’s proof process and couldn’t keep his calm any longer, standing up abruptly.
"What are you pretending for, Lu Sheng?!" Fu Chen spoke righteously.
"The exam ended several days ago; you could have thought about other methods for this question afterward, or you could have taken the question and asked someone for a more sophisticated solution."
"You don’t think that by writing a different proof method here, you can prove that you didn’t cheat or copy answers, do you?"
As soon as Fu Chen said this, the classroom, previously engrossed in discussing solutions, was once again drawn back to the allegations against Lu Sheng of cheating and copying answers.
Lu Sheng looked at Fu Chen coldly.
Admittedly, what Fu Chen said made sense.
The exam had indeed passed several days ago, and no matter how many simpler and more sophisticated solutions she provided now, they could all be thoughts she had afterward or learned from asking others.
There was simply no way to prove her innocence.
But Lu Sheng hadn’t been counting on proving her innocence just by writing these two proofs on the blackboard.
She was just buying time.
Buying time... for Huo Yu to find evidence for her.
At that moment, Lu Sheng’s gaze moved past Fu Chen and landed on Huo Yu at the back of the classroom.
As she looked towards Huo Yu, Huo Yu also happened to look up and their eyes met.
In the instant of their gaze meeting, Lu Sheng saw a hint of confidence and certainty in the boy’s eyes.
And she felt relieved.
So the next second, Lu Sheng did not argue with Fu Chen; instead, it was Huo Yu, at the back of the classroom, who suddenly spoke up.
"Indeed—no matter what Lu Sheng says now, she can’t prove her innocence."
"I think this is the effect that the person who framed her wants to achieve."
The cool voice of the teenager rang out in the classroom, attracting everyone’s attention. 𝖓𝔬𝔳𝖕𝖚𝖇.𝖈𝔬𝔪
If Lu Youming in the school and classroom was aloof, and had the halo of a superior-looking, handsome and privileged student that nobody dared to approach,
Then Huo Yu was purely silent.
As the only top student in the class, sitting alone in the corner of the classroom, he usually kept his head down and did his own things, with very low presence and completely ignored by the class.
This sudden act of speaking out in the classroom and drawing everyone’s attention was the first of its kind for Huo Yu.
His sudden speech made many people even ignore what he said; their first reaction was—
Holy crap, who’s this guy, his voice is so good!
Many in the class were seeing Huo Yu fully lift his head in front of everyone for the first time.
He was slender. His slightly loose uniform jacket matched with a meticulously tied shirt and tie. His skin was pale from lack of sunlight exposure, and his facial features were sharp and distinct.
The soft hair in front of his forehead slightly covering his brow and eyes, with long black eyelashes almost casting a shadow. With straight nose and thin lips, the cold look in his eyes gave a sense of clarity and toughness, and his demeanor carried a silent resilience.
Many girls in the class were spellbound, all thinking:
Holy crap, was Huo Yu always this handsome? How could we have never noticed before?!
He totally qualifies to be part of the selection for the school’s most handsome guys! How could this gem have slipped through the net?!
Huo Yu was unaware of what others were thinking.
Zhou Wu, after hearing what he had just said, paused for a moment and asked, "...Huo Yu, what did you just say?"
"Did you just say someone framed Lu Sheng?"
Huo Yu lifted his gaze, his eyes unwavering, and answered, "Yes."
"Lu Sheng’s paper has indeed been switched. If evidence is needed, everyone just look at the big screen."
As his words fell, the big screen in the classroom, which had previously displayed the exam paper comparisons, suddenly flickered and turned into a completely new interface.
Upon discerning the text on the screen, everyone in the class widened their eyes—if they weren’t seeing things wrong, what was now before them... was the internal system of the Beijing University and Qing University admissions office??
