They're already in university, and the primary school system is only just starting out?

Wednesday, 9:30 a.m.

In dormitory 406 of Yannan University, sunlight streamed through the gaps in the curtains, casting a bright spot on the desk.

Chen Lin opened his eyes with some difficulty; he had gone to bed a little late last night.

He grabbed his phone from the bedside table and glanced at the time, only to realize that the dormitory was unusually quiet.

He sat up in bed and looked around.

Goodness, all three of my roommates have already left.

Chen Lin smiled knowingly.

These three are such a handful; they're always having a blast in the dorm, either playing some super-intense online battles or watching short videos all night long.

But when the final exams came, their scores were higher and higher.

Everyone is working hard silently in places unseen by others.

In the past, having a roommate like Chen Lin, who was only interested in making money and had no interest in studying, and who relied entirely on cramming for his major courses, gave everyone some psychological comfort, as they felt that there was always someone helping them fall behind.

But now, things seem to have changed a bit.

Chen Lin first worked with Shen Yan from the mathematics department on some advanced modeling competition.

Then, I heard that Chen Lin was singled out and praised by Old Wang in his professional class.

It's estimated that these three brothers truly felt the pressure.

This morning I'm either going to class or to the library to study.

Chen Lin shook his head, a little amused to himself.

What he really wanted to say was, "Brothers, don't get me wrong, I'm still only focused on making money!"

It's just that because he has the system, he has changed his attitude towards life, so it looks like he is studying seriously.

He slowly got up, washed up, and began planning his morning.

I had already made an appointment with Shen Yan this afternoon to help her look at the professor's research topic that she found difficult.

Should I continue studying the book "Python Mathematical Programming" from yesterday in the morning, or catch up on the TV series I was halfway through watching yesterday?

Chen Lin doesn't actually have a habit of watching TV dramas.

Firstly, his previous part-time jobs were so full that he simply didn't have the time.

Secondly, his impression of domestic TV dramas mainly comes from those highly-viewed吐槽 videos on video websites—the five-cent special effects, the studio-style costumes and props, and the scripts typed out by monkeys on typewriters, which made him keep his distance.

But there are always exceptions.

Yesterday afternoon's elective course was "Film and Television Culture Studies." The professor for this course is a middle-aged lecturer with a strong artistic flair. He lectures in a humorous and engaging style, and he's very lenient with his grades, so it's always difficult to get a spot in his class each semester.

Yesterday, the teacher talked about "how period dramas depict the changes in society over the past few decades".

In class, the teacher showed clips from several well-regarded period dramas and assigned a major homework assignment: each student should choose one period drama to watch and write an analysis of no less than 2,000 words, to be submitted one month later.

Chen Lin immediately took a liking to a TV series called "The Long Season".

The cinematic quality of the clips, along with the color palette and soundtrack, really suited his taste.

In addition, the teacher mentioned that the drama also had a suspenseful element, which made Chen Lin very interested.

So last night, he went back to his dorm, put on his headphones, and binge-watched nine episodes in one go, only going to sleep around 1 a.m., still wanting more.

Looking back now, Chen Lin feels that choosing this elective course was incredibly wise.

Both are worth two credits, but watching TV dramas is at least more interesting than studying "Dream of the Red Chamber" or public relations writing.

However, Chen Lin ultimately decided to go to the library to continue reading "Python Mathematical Programming".

"Making money is the priority."

Chen Lin muttered to himself.

Learning programming early will allow you to better utilize your abilities as a "little mathematician".

Once he made the decision, he didn't hesitate any longer. He picked up the book "Python Mathematical Programming" from yesterday, slung his laptop over his shoulder, and headed straight to the library.

Walking along the tree-lined path leading to the library, the midday sun wasn't too harsh, casting dappled light and shadow through the dense foliage.

Chen Lin remembered that he had been watching TV dramas since he returned to his dorm after his elective class yesterday, and hadn't watched any of his favorite shows for most of the day.

As he walked, he took out his phone and skillfully opened the Xianyu app.

As soon as I opened it, a red notification dot popped up.

Chen Lin was slightly startled. Could he have really missed out on a client?

He opened the message list and found that the message was from the same customer with the ID "Phoenix Institute Kyouma" from last time.

I sent myself a string of messages.

[Yesterday 22:50]

Phoenix Inu no Kyouma: [Great God, are you asleep?]

[1:39 AM today]

Phoenix Inu no Kyouma: [Great God, please reply to this message?]

[8:46 AM today]

Phoenix Institute Kyouma: [Master, could we arrange a place to meet in person at Yannan University?]

Phoenix Institute's Kyouma: [Master, our company is interested in collaborating and would like to discuss this with you in person.]

Wow, a box?!

Chen Lin paused in his steps.

He stared at the last two messages, his mind racing, countless thoughts flashing through his mind in an instant.

What's going on?

He was a little unsure of the other party's true intentions.

Is it that they genuinely want to discuss cooperation offline, or has someone with ulterior motives seen their proposal and wants to trace them back to them?

Although the former is more likely, Chen Lin has always believed that it is better to be safe than sorry.

He decided to play it safe and play it safe.

Chen Lin stood still, pondered for a moment, typed a line of text on the screen, and clicked send.

Sorry, I only provide online services.

He had made up his mind that if the other party insisted on meeting in person, he would block them no matter what conditions they proposed.

Although you might get a complaint for "not using up your consultation time" and lose some credit points, it's nothing compared to your own safety.

Thinking about this, Chen Lin couldn't help but feel a surge of relief. Luckily, he had been careful not to add the other person as a WeChat friend directly.

With just a Xianyu account, it's unlikely that any trace of him can be found in the meeting software. It shouldn't be easy for the other party to find out his real identity.

He glanced at the chat interface and saw that his message was still marked as "unread," indicating that the other party was not online at the moment.

Chen Lin put away his phone, stopped thinking about it, and continued walking towards the library.

Just then, my phone vibrated again, and the screen lit up with a WeChat message notification.

He clicked on it and saw it was Shen Yan.

Shen Yan: [Chen, are you free at 1:30 this afternoon?]

Chen Lin: [Sure, where shall we meet?]

The message was sent out and received a reply almost instantly.

Shen Yan: [Let's go to the usual place, the study room.]

Chen Lin: [OK]

Upon arriving at the library, Chen Lin again secured a single study room, then took out his computer and the book "Python Mathematical Programming" to continue studying.

I finished reading the first two chapters yesterday. The third chapter is about the statistical characteristics of data.

The mathematical knowledge inside is actually quite basic and is used to help readers connect with the code.

Chen Lin glanced at the terms in the catalog: "mean", "median", "variance and standard deviation", "correlation coefficient", etc., and had already figured out the concepts and related formulas in his mind.

He flipped directly to the code section and began typing out the code from the book on his computer: 【def caculate_mean(numbers)】

s = sum(numbers)

N = len(numbers)

mean = s/N

return mean]
