Enjoy the show, everyone, and don't forget to wire the money!-Morando na cidade pequena, você diz que sou o chefão?(Fora da floresta)

The "People with an IQ Above 150" group chat instantly erupted.

Among these individuals, "Listening to a Man Talk Nonsense" was a Ph.D. candidate at Peking University, while "Eating Seven and a Half Bowls in One Go" was a graduate student at MIT. Both possessed extremely high credentials, especially in the field of mathematical modeling. Consequently, how could they not feel infuriated when the mathematical model they had built was mercilessly mocked by an undergraduate student from a regular state university?

People immediately began shouting back in refutation. "Eating Seven and a Half Bowls in One Go" even directly tagged Fang Qingye, but unfortunately, Fang Qingye had blocked this group and could not see it at all.

At that moment, the Dongguan Girl messaged him again: "My hubby, your analysis makes a lot of sense. I think so too, but it seems none of them agree with what you said."

"Did you copy our conversation into the group?!" Fang Qingye immediately realized.

"Yeah, we were just discussing... Rest assured, I won't make our sweet talk public. That's our little secret, oh."

Sweet talk your head.

Who was talking sweet talk with you?!

Fang Qingye ignored her remark and simply replied flatly, "Whether they agree or not, what does that have to do with me?"

"My hubby, don't you want to prove that you're better than them? That your IQ is higher than theirs? To see the great you make them feel so insignificant?!"

Seeing the text sent by the Dongguan Girl, Fang Qingye smiled.

This reverse psychology...

Probably only someone with an IQ of two hundred and fifty could come up with it.

He thought for a moment and typed back:

"I can build a mathematical model, but it's going to cost extra!"

"How much?"

"At least five hundred thousand!"

The other person paused for a few seconds before replying.

"Deal, but I have conditions."

"What conditions?"

"The model has to perform better than those two, and it needs to be completed by this exact time tomorrow at the latest!"

"No problem. Just wait, I'm starting the model now," Fang Qingye replied.

"Now? How long will it take?"

"Before off-work time, I suppose." Fang Qingye checked the time on his phone; there were still two hours left until the end of the workday.

"OK! It's a deal. Burn, Pikachu!"

Fang Qingye was about to go offline when a sudden thought crossed his mind, and he typed:

"Did you copy our recent conversation into the group again?"

"Of course! I want them to witness my hubby's prowess! A falling meteorite is about to strike—brace yourselves, all of you!"

Fang Qingye gave a faint smile, said nothing more, and put down his phone.

By this time, the chat group had descended into total chaos.

"What kind of skills does he have to build a mathematical model in two hours? And make it better than ours?"

"He's just bragging! If he had that kind of skill, he wouldn't still be stuck at a state-owned bank; Citibank and Morgan Stanley in Shanghai would have already rolled out the red carpet to welcome him!"

......

Uncharacteristically, the Dongguan Girl did not defend Fang Qingye.

Perhaps she, too, felt that the guy was just blowing smoke.

Naturally, Fang Qingye could not see the messages in the group; he had already started working on the model.

He knew very well that, according to conventional logic, it was utterly impossible to build such a demanding and complex mathematical model within two hours.

However......

I am a reborn person.

What is the absolute hottest thing more than a decade from now?

AI.

Before his rebirth, Fang Qingye had already built a similar mathematical model using DeepSeek, which had been released in China just a few days prior.

Things that required humans to rack their brains over were a breeze for AI.

Following his memory, Fang Qingye typed rapidly, softly humming the most popular song of that summer:

*Writing a poem for you, stopping time for you*

*Doing the impossible for you*

*Playing every romantic verse for you*

......

Huh....

If I get rich in the future, how about we also build our own large AI model to play with?

Why build it ourselves, wouldn't it be easier to just poach Liang Wenfeng from DeepSeek directly.....

Just as Fang Qingye was typing away gleefully, a faint fragrance suddenly drifted over from beside him. Without him noticing, Cao Ting had walked up and was curiously peering at his screen.

"Xiao Fang, who are you writing poetry for?"

"No one, just building a mathematical model." Fang Qingye instinctively shifted his body to the side.

Cao Ting looked somewhat disappointed.

She had genuinely thought Fang Qingye was writing a poem for some girl.

As for things like mathematical models, she neither understood nor cared about them, but she still chimed in with a couple of casual remarks.

"Impressive, I suppose. Why are you writing this stuff?"

"Doing a favor for a friend, just messing around," Fang Qingye replied casually.

"Must be a guy, right? No girl likes this kind of stuff," Cao Ting remarked again.

Not necessarily.

The Dongguan Girl liked it.

By this point, Fang Qingye was certain that the Dongguan Girl was indeed a girl. As for whether she was unattractive or not, that remained up for debate.

Of course, there was no need for him to say that.

Finding it uninteresting, Cao Ting glanced at him, returned to her seat, and went back to playing with her phone, while Fang Qingye continued with his modeling.

An hour and a half later, a brand-new credit risk assessment scorecard model was completed, adopting a logistic regression model:

$$y = f(x; heta)=frac{1}{1 + e^{-( heta_0 + heta_1x_1 + heta_2x_2 +ldots + heta_nx_n)}}$$

Where $y$ represents the output result (credit risk),

$x$ represents the input features (customer information),

$ heta$ represents the model parameters, and $f$ represents the model function.

......

Fang Qingye carefully checked the formula to ensure there were no errors, and then plugged in the data provided by the Dongguan Girl for evaluation. The results were highly satisfactory; although there were minor deviations, it was far superior to the two amateur models built by those two fools.

Done!

Fang Qingye looked at his watch—it had taken exactly two hours.

Without hesitation, he immediately opened QQ and sent a message to the Dongguan Girl: "I've finished writing it. Sending it to you now."

"Really???"

Followed by a string of question marks.

Without saying much else, Fang Qingye immediately transferred the document.

"Alright, look it over slowly. Don't forget to pay up!"

With that, Fang Qingye went offline. Work was over, Cao Ting had already left, so why would he linger in the office?

He quickly tidied up his desk, locked the office door, went to the bicycle shed to fetch his little scooter, and puttered leisurely toward home.

What he did not know was that the group chat for people with an IQ above 150 had completely exploded.

As it turned out, the Dongguan Girl hadn't even looked at the file; she had directly posted the mathematical model Fang Qingye sent her into the QQ group space and tagged everyone:

"This is the mathematical model my hubby built in two hours. Everyone passing by, come take a look."

Responses poured in immediately:

"He built a mathematical model in two hours? Fair maiden, please don't insult our intelligence, including your own, okay?"

"OK! Fair maiden, please don't waste our time. Our time is very valuable."

"I suggest kicking this guy out of the group. He's directly dragging down our school's prestige and our intellectual standards!"

......

"Hey, are you lot too chicken to look? Stop flapping your jaws here and read it first before you talk to this lady!"

The Dongguan Girl flew into a rage and fired off a blunt message.

The group quickly fell silent.

10 minutes passed.

20 minutes passed.

An hour passed.

Still, no one in the group uttered a sound.

"Hey, are you all mute? I've already finished my meal, how come nobody's saying anything? Did you actually look at it or not?!" The Dongguan Girl's message appeared on the public screen once more.

Beneath it, dead silence persisted.

What she did not know was that in another chat group—a private group established by the other 13 members excluding the Dongguan Girl and Fang Qingye—messages were scrolling by incessantly.

"Seven and a Half, did you look at it? I think this mathematical model is better than yours."

"I'm studying the damn thing right now, stop nagging," the other person replied rather bluntly.

"Hey, Senior Sister, you have the highest modeling proficiency among us in this group. What do you think of it?" Someone tagged "Listening to a Man Talk Nonsense" again.

After quite a while, the other party replied: "I've finished reading it. Its level is indeed higher than the one Seven and a Half and I built. Now I have to harbor some doubts."

"Doubts about what?"

"I doubt what the fair maiden said. Is that Donghai Swordsman really just an undergraduate graduate from Shanghai University of Finance and Economics? With his modeling speed and proficiency, even I, a proud Ph.D. candidate from Peking University, cannot match him. How could he possibly be an ordinary clerk at a grassroots bank?"

As soon as "Listening to a Man Talk Nonsense" sent that line of text, a brief silence descended upon the group.

A moment later, "Handsome Enough to Slow Down the Internet" sent a reply: "The fair maiden went to the same school as me. I ran into her in the cafeteria a while ago and chatted about this. She said the Donghai Swordsman is indeed an undergraduate graduate from Shanghai University of Finance and Economics, and his transfer address is a grassroots bank in Jiangsu Province."

"What's his name?"

"Fang Qingye."
