I really don't want to date a girl addicted to the internet!

The boy remained motionless, as if he couldn't hear him.

"I'll count to three." A cold glint flashed in Lin Xuanqi's eyes.

"one."

"two."

"three……"

The boy suddenly looked up and blocked her countdown.

Lin Xuanqi stiffened for a moment, then squinted and relaxed, the coldness fading away.

A few minutes later, the boy rubbed his waist and grimaced, "Xuanqi, you were too rough."

"Cheng Fei, I've noticed you're getting bolder and bolder?" the girl said, pinching his cheek.

“Xuanqi, you’re older.” The boy glanced down casually.

"Alright, behave yourself during work hours." The girl rolled her eyes at him, straightened her disheveled collar, and said, "Tell me about your scallops."

"Didn't you give me this ticket, Xuanqi? I think the technical chart looks good, and the fundamentals are fine too." The boy frowned when he mentioned this.

Lin Xuanqi opened the trading software on her phone, squinted as she switched between different candlestick charts and indicators, and then asked someone to bring her a research report to read carefully.

"It was purely an accident; no one could have predicted something like this." The girl shook her head, like a forensic doctor announcing the cause of death.

"Could scallops really run away?" Cheng Fei asked incredulously.

"Who knew that this kind of seafood business is difficult to regulate? He suddenly said that all the scallops died. Are you going to personally dive into his underwater ranch to investigate? The key question is, has your money been stolen?"

Two thin, long green bars suddenly appeared at the far right of the stock's candlestick chart, resembling a bottomless abyss.

"I've sold them all, but I still haven't sold half," Cheng Fei said.

"Keep the price at the daily limit down during the opening auction. Don't hold onto any illusions. Anyone who hesitates at this point is just a sucker." Lin Xuanqi said expressionlessly.

"Understood." The boy's expression was grave.

Looking at his expression, Lin Xuanqi revealed a malicious smile and reached out to pinch his cheek. "What, you can't even handle this little accident? You still want to make investments?"

"It's not that I can't stand it, it's just that I seem to be a bit unlucky." The boy sighed, quite seriously.

"That's pretty unlucky. There's a fund manager next door who was bullish on this stock, and now they're all dumbfounded." Lin Xuanqi stared at him with interest, her tone not without malice.

The boy pondered, "Xuanqi, do you think I should buy industry funds or index funds? I feel that with my luck, buying individual stocks will only lead to continuous losses."

"If you're afraid to touch individual stocks, then don't bother learning about investing; you'll be an amateur your whole life." The girl made no attempt to hide her disdain.

"Okay." The boy nodded honestly.

“However, if you really don’t trust yourself, you can try another approach,” Lin Xuanqi said, changing the subject.

"What approach?"

"Do quantitative investing."

What does quantitative investing mean?

"Simply put, it's about turning your investment strategy into a mathematical model. Nowadays, deep learning is often used to train AI for trading. AI stock selection is absolutely objective and can be very large, so you don't have to feel like you're just unlucky."

"Then isn't that much better than others? Why didn't you say so sooner?" the boy exclaimed in delight.

"You're dreaming." Lin Xuanqi laughed. "It's just a trading method with relatively stable risks and rewards. You can do it, but you can't neglect this part. Market sense is something you develop through practice. You only learn from your mistakes. I already told you to consider the 100,000 as tuition."

The boy thought for a moment, "Then how exactly do you do quantitative investing? Can you teach me?"

"You really want to do it?" The girl raised an eyebrow.

"Yes." The boy nodded emphatically.

"Come with me to Yushui Garden tonight, and I'll find someone to teach you. How about it?" Lin Xuanqi's lips curled into a malicious smile.

The boy glanced at the depths of her thighs, which were encased in semi-transparent pantyhose, and said calmly, "Okay."

"Good boy." The girl patted his face with satisfaction.

……

148. Cheng Fei threw himself into new studies.

Lin Xuanqi made a phone call using the landline on her desk, "Have Liu Tao from the technical department come to my office."

Not long after, the young, fat man he had seen before appeared in front of Cheng Fei.

"I'm giving you a task this week: mentor him in quantitative investment," Lin Xuanqi ordered casually.

"Huh?" Liu Tao was stunned.

"Is there a problem?"

"I... I've never mentored a new person before."

“This isn’t formal training. He’s interested in this, so you can teach him when you have time, understand?” Lin Xuanqi said expressionlessly.

"I understand, I understand." Liu Tao nodded quickly, secretly sizing up the young man and woman in front of him.

So Cheng Fei left Lin Xuanqi's office for the time being and went to the technical department with Liu Tao.

Upon arriving at his workstation, Liu Tao pushed a chair over to Cheng Fei, saying, "Come on, Brother Cheng, have a seat."

“You’re older than me, I should call you Brother Liu.” Cheng Fei was sweating a little.

"Age doesn't matter, ability is the most important thing. Just call me Xiao Liu." Liu Tao pressed him into a chair.

"Brother Liu, let's get down to business."

"Okay, Brother Cheng, let me ask you something first: do you know Python?"

"will not."

"What about C?"

"No, not at all."

“You have great potential.” Liu Tao gave a thumbs up. “So, do you want to do the quantitative model yourself, or do you mainly hope that I can assist you?” He was very careful with his words.

"I want to learn to the point where I can complete tasks independently," Cheng Fei said earnestly.

"I'll teach you, and then we'll do it together?" Liu Tao said tentatively.

"You just need to teach me, I learn things very quickly," Cheng Fei said seriously.

Liu Tao wiped his brow. "Alright, let's start from the basics. Let's figure out how to set up the environment first. Also, you'll need to read some books later. I'll recommend two..."

"Ok."

……

So Cheng Fei spent the rest of his time studying.

That evening, Lin Xuanqi took the boy out for a kaiseki meal, and then they returned to her villa on the banks of the Huangpu River.

Lin Xuanqi sat on the sofa with one leg crossed, flipping through financial reports. The boy consciously finished cleaning his mouth and came to her, climbing onto her chocolate-silky black semi-transparent pantyhose.

"Xuanqi, always crossing your legs is bad for your lumbar spine," the boy said softly, tucking a cushion behind her back.

Lin Xuanqi's body slid down a little uncontrollably, but the girl remained unmoved, her gaze still fixed on the financial report. She gradually narrowed her eyes, reached down with one hand to stroke the boy's face, and her expression revealed an indescribable enjoyment and pleasure.

……

An hour later, Cheng Fei took a taxi home and, as usual, bought a bottle of soda water on the roadside to rinse his mouth.

As expected, I still couldn't stand it, I just couldn't get used to it, even though the object of my affections was a top-tier beauty like Lin Xuanqi.

But this is for the best. The more Lin Xuanqi does such things, the deeper his hatred for her will become. When the day comes for revenge, he will definitely humiliate her tenfold or a hundredfold.

Filled with intense hatred, the boy returned to the rented room, found the shampoo prop he had made last time in the corner of the kitchen cabinet, took out the pantyhose Lin Xuanqi had given him as a reward, which still retained her body heat, squeezed it a couple of times, dripped a few more drops, took a picture, and sent it to Lin Xuanqi.

"good"

A satisfactory reply came from the other side.

This woman will definitely show that sickly smile again when she sees the photo.

Cheng Fei, being a perfectly normal person, couldn't understand what was so interesting about this, but as long as she was happy, that was all that mattered.

……

Wednesday was a holiday for New Year's Day. After breakfast, Cheng Fei went to a nearby bookstore to buy books as Liu Tao had suggested.

"Python: From Beginner to Practice", "Python Programming Quick Start Guide", "Python Memorization Handbook", plus "Introduction to Deep Learning".

As he paid the bill, a cool, aloof girl with long, dark hair appeared behind him, carrying several books.

"Teacher Shen, what a coincidence!" Cheng Fei exclaimed in surprise.

"Is flying fish rampant this season? They're everywhere." The girl frowned slightly, as if she had seen cockroaches while walking by the roadside.

"Teacher Shen, you look adorable today." Cheng Fei smiled as he observed the warm, creamy-white fleece fisherman's hat on her head, marveling that he had indeed made the right choice.

"Stop giving me that disgusting look." The girl frowned, her face showing disgust.

The two walked out of the bookstore side by side, carrying bags.

"Teacher Shen, can you finish reading all these books?" the boy asked, looking her up and down.

Shen Xi bought five books, one more than Cheng Fei, and the thickness of each book was about the same.

“I can finish reading this in a day.” The girl tossed her long hair.

"What a coincidence, I also plan to finish watching it in one day."

"How arrogant! Don't try to outrun me by rushing things." The girl sneered.

"Teacher Shen, although you are very smart, don't forget that you are currently being suppressed by me."

"Goodbye." The girl's expression changed, and she turned at the intersection and walked away without looking back.

Cheng Fei watched her slender figure disappear into the distance, then turned and went back to his rented room.

The boy spent the whole day studying. In the afternoon, his laptop, which he had ordered online, arrived. After configuring the development environment, he started exploring and practicing until 2 a.m. before going to bed.

The next day, I woke up refreshed at 6:30 in the morning to my alarm clock.

His physical strength and rapid recovery have made it difficult for him to wake up on time recently, but he has saved about two hours of sleep time almost every day.

He now suspects that once his stamina reaches an extraordinary level, he will only need to sleep two or three hours a day.

Cheng Fei continued attending classes at Yinghua. He planned to accumulate some questions before seeking help from Liu Tao, which would be more efficient and reduce Liu Tao's burden. Cheng Fei didn't want to make things difficult for the working class.

The boy made the most of his breaks and lunch breaks to study, and Chen Hao and the others got used to his recent habit of reading a lot of extracurricular books. Only Zhou Han dragged Ruan Jingyi over at noon to sit in front of him and ask him for help with math problems, and they stayed on his desk for a long time.

He managed to sell the last portion of his scallop-related stock before the market closed in the afternoon, giving him a real taste of what it means to be trapped and killed.

The account's total returns hit a new low, but he's numb to it. It doesn't matter; he's going to switch to quantitative investing anyway, and it's already at rock bottom, so it's going to go up no matter what.

In the afternoon, the boy, with his hands in his pockets, climbed onto the rooftop of the club activity building and pushed open the door to room 601.

The aloof young woman with long, dark hair sat alone in the steel tube chair, reading a book, seemingly an unchanging scene from time immemorial.

"Good afternoon, Ms. Shen." Cheng Fei sat down next to her.

"Good afternoon, Cheng Fei," the girl, who seemed to be in a good mood, said expressionlessly while looking at her book.

"Teacher Shen, why aren't you wearing the hat I gave you today?" Cheng Fei asked, taking his laptop and books out.

"Does giving it to me mean I have to wear it every day? If that's the case, I'll never wear it again." Shen Xi said coldly.

"I didn't mean that. It's just that you look so cute in that hat. Your face is already small, and it looks like a little animal in the snow when it's hidden under the fluffy hat. By the way, I also really like your rebellious spirit." The boy opened his programming software and continued writing the code he hadn't finished yesterday.

"If wearing that hat caused you to have such disgusting delusions, then I'm sorry, it was my fault." Shen Xi looked disgusted.

……

149. Cheng Fei believes that safe words are necessary.
