This top-tier academic genius

Somewhere, behind the screen, [Half a Peach] felt a sudden unease when Lin Yan agreed so readily, her heart skipped a beat.

But the words were already spoken, so I had no choice but to bite the bullet and quickly type out a more difficult problem, then sent it to the screen: 【Given the function f(x) = x³ − 3x² + 2x, find its extreme points and extreme values, as well as its monotonic intervals! One minute, timer starts!】

This problem is much more difficult than the previous one. It involves solving derivatives and extreme points. Even a high-achieving senior high school student would need three to five minutes to solve it. It is almost impossible to finish it in one minute.

It was precisely because of this that [Half a Peach] deliberately set a one-minute deadline.

She was certain that even if Lin Yan was truly skilled, it was impossible for him to solve the problem in such a short time.

Holy crap! Half a peach is serious! This problem takes me three minutes to solve!

[Oh no, this streamer is going to mess up! One minute isn't enough!]

[Half a Peach is so cunning! He deliberately set such a difficult question!]

[@HalfPeach, are you deliberately making things difficult for me? But I still believe in the streamer!]

The comments scrolled rapidly, with some people holding their breath for Lin Yan and others waiting to see him make a fool of himself.

Meanwhile, [Half a Peach] was smug, constantly spamming the chat with urging: [Fifty seconds left! Streamer, hurry up and solve it! Apologize if you can't solve it!]

However, just as the comment "Half a Peach" was sent, Lin Yan picked up a pen and began to quickly calculate on the draft paper. The pen tip moved across the paper at an astonishing speed, and the handwriting was neat yet smooth, without the slightest pause.

The viewers in the live stream all held their breath, staring at the draft paper in the camera's view, and even the comments on the screen slowed down a bit.

In just twenty seconds, Lin Yan stopped writing, turned the draft paper towards the camera, and clearly showed the complete solution process and answer:

「解：f』(x)=3x²−6x+2，令f』(x)=0，解得x=1±√3/3；极值点为x=1−√3/3（极大值点），x=1+√3/3（极小值点）；极大值为f(1−√3/3)=2√3/9，极小值为f(1+√3/3)=−2√3/9；单调递增区间：(−∞，1−√3/3)，(1+√3/3，+∞)，单调递减区间：(1−√3/3，1+√3/3)。」

At this moment, only forty seconds had passed on the alarm clock, which was one-third faster than the one minute required by [Half a Peach]!

The live stream chat instantly went wild, with so many comments that the screen was almost completely obscured!

[Holy crap! Holy crap! Holy crap! Forty seconds! What kind of god-like speed is that?! It would take me a minute to copy that.]

[Complete solution! Absolutely perfect answer! Is the host a genius?!]

[Half a peach! Come out! Keep your promise! Ten rockets + live stream of eating shit, stop playing dead!]

[I really misunderstood the streamer before! This isn't just pretending to be a top student, this is a genuine academic genius!]

[I'm a fan now! This streamer is amazing! He's so focused on learning and still so talented. I'm a fan now!]

However, [Half a Peach] remained completely silent. No matter how many viewers tagged him, he didn't post a single comment. Clearly, he had been thoroughly humiliated by Lin Yan and was too cowardly to utter a sound.

Not long after, a viewer reported: "[Brothers, Half Peach ran away! I just saw her profile picture is grayed out, she's already left the live stream!]"

Even more resourceful viewers managed to uncover the true identity of "Half a Peach": "Haha, I found out! This 'Half a Peach' is the same person on Huibo, @LoveLuZe365Days! Turns out she's a fan of Lu Ze!"

This comment caused another surge of excitement in the live stream.

[So that's it! No wonder they're targeting the streamer so much; they probably think the streamer's past "academic genius" persona is an attempt to piggyback on her idol's fame, right?]

[Poor Lu Ze, having such a brainless fan is so embarrassing!]

[Haha, I heard Lu Ze is also a recognized academic genius in the entertainment industry. I wonder who's better, him or the streamer?]

Lu Ze, as described by the audience, is a top-tier young actor in the entertainment industry. He is not only good-looking and popular, but also has always presented himself as a "top student".

When Lin Yan was in the Time Boys group, his agency forced him to replicate Lu Ze's academic genius persona in order to quickly make him famous. Unexpectedly, a live broadcast went wrong, which completely ruined his reputation and led to his termination of the contract with the company.

Lin Yan glanced at the comments and spoke calmly, his tone still composed: "It seems some people not only freeload off others, but also break their promises. Alright, I won't take up any more of your time, I'll go back to reading."

After saying that, he ignored the noise on his phone screen and let the live stream continue, returning to his studies.

Next, he plans to do several math practice tests to reinforce his knowledge, fill in any gaps in his understanding, and strive to raise his math level to LV1 as soon as possible.

Lin Yan took out "Five Years of College Entrance Examination and Three Years of Simulation" from under the table, randomly picked out a set of senior high school math past papers, and started answering the questions directly.

The first question is about the intersection of sets, extremely basic: Let set A = {x | −1}

Lin Yan didn't even need to write anything down; a glance was enough to arrive at the answer: the answer was B{0, 1, 2}.

These basic questions are a piece of cake for him now.

Of the eight multiple-choice questions, Lin Yan only wrote down the answers for two of them; he could figure out the answers to the others in his head with a little mental calculation.

In fact, there are techniques for answering multiple-choice questions. Eliminating incorrect answers by using the options is much more time-efficient than performing a full calculation.

In less than twenty minutes, Lin Yan finished answering all the multiple-choice and fill-in-the-blank questions on the test paper, and all of them were correct.

He raised an eyebrow slightly, thinking to himself: The difficulty of this test paper is still too low; it's not enough to fill in any gaps in our knowledge.

Fortunately, Lin Yan went through three sets of past exam papers in one go, his pen never stopping, and his answering speed became faster and faster. He thoroughly enjoyed the feeling of being able to answer all the questions with ease and confidence.

You should know that doing problems used to be torture for him. He would get stuck on a single problem for half a day and couldn't even understand the question.

He nodded in satisfaction. It seemed that he had almost mastered the key points of high school mathematics. All that was left was to practice more problems, hone his skills, and improve his answering speed.

Only then did he glance at the time and realize that it was already 11 p.m.

To his surprise, there were still nearly 500 people watching the live stream.

After the initial excitement subsided, many onlookers left, but quite a few stayed.

Among the remaining viewers, a small portion were long-time fans who had been silently supporting him, some were former haters who had become fans after being won over by him, and the rest were casual viewers attracted by his focus and talent.

What made Lin Yan even more gratified was that the style of the comments in the live stream had completely changed. Instead of mockery and teasing, a group of people were discussing math problems in the comments.

Some asked about junior high school geometry, some about high school functions, and others shared their problem-solving techniques, turning it into a mini learning livestream.
