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

"Eh, have the two of you gotten this close?" Nagasaki Asuna's surprise seemed genuine.

Shen Xi's face was indifferent.

"To be honest, I've been to her house several times already," Cheng Fei nodded.

“I see.” Nagasaki Asuna’s dejection seemed genuine.

Shen Xi stared at the book, her face expressionless.

……

154. Cheng Fei is a teacher.

In the quiet room, a cool and aloof girl with long, dark hair sat at the table reading a book, while Cheng Fei chatted with Nagasaki Asuna via video call next to her.

"Um, Mr. Cheng Fei, I have a few questions." The girl in pajamas on the other end of the camera raised her hand with a playful smile.

"Please speak." Cheng Fei glanced at Shen Xi beside him.

Shen Xi seemed very engrossed in watching, not raising her head and not blinking.

"So now that I've set up the environment, what else is there to do besides getting familiar with the code?" Nagasaki Asuna poked her fair cheek with a water-based pen.

“While you’re familiarizing yourself with the code, I suggest you start developing a task plan.” Cheng Fei thought for a moment. “The first step is to define your goal; in short, what kind of AI do you need?”

Nagasaki Asuna pondered, "If we send it a screenshot of the constellations in the corridor, it can instantly calculate the latitude and longitude of the AI?"

“That’s an AI for image recognition,” Cheng Fei said.

“Okay, I’ll write this down.” Nagasaki Asuna said like an obedient schoolchild, “Teacher Cheng Fei, what’s next?”

"The next step is data collection and processing."

"What specific data is it?" the girl asked, tilting her head.

"For you, it's just different constellations and their corresponding latitudes and longitudes. You need to find a way to collect a lot of data and put it into the neural network for training." Cheng Fei shrugged.

"Let me think, are the data we calculated by hand enough?" Nagasaki Asuna blinked.

“That’s far from enough. You’d better find some astrology-related software to batch output star images and their corresponding latitude and longitude.” Cheng Fei paused. “The ones we calculate by hand can be used for subsequent optimization. Professor Shen, you didn’t lose the previous drafts, did you?” He turned his head.

"Still here." Shen Xi said expressionlessly.

"Then please hand everything over to Nana later."

"Okay," Shen Xi said, looking annoyed.

"Shen Xi, thank you for your help," Nagasaki Asuna greeted from the other end.

Shen Xi remained indifferent and did not respond to her.

Nagasaki Asuna didn't mind and continued, "Teacher Cheng Fei, what's the next step?"

"Nana, this kind of thing was actually mentioned in the materials I sent you, right?" Cheng Fei looked at her helplessly.

"Nana is a bit slow, so I'll have to trouble Teacher Cheng Fei to take good care of her, hehe~" Nagasaki Asuna clenched her fist and tapped her head, winking playfully.

Shen Xi, standing beside her, took a deep breath.

Cheng Fei remained expressionless. "The next step is to select a model and begin training."

"Which model should I choose? There seem to be many kinds of neural networks." Nagasaki Asuna flipped through the information.

“For image recognition, a convolutional neural network will suffice,” Cheng Fei replied immediately.

"Wow, as expected of Teacher Cheng Fei, so amazing~" The girl clapped lightly with a serious expression.

Shen Xi took another deep breath.

Cheng Fei said expressionlessly, "Because I use a different neural network for quantitative investment, you'll have to figure out the parameters yourself."

"Understood." Nagasaki Asuna gave a crooked salute, then thought for a moment, "Teacher Cheng Fei, do we need a high-performance computer for training?"

That's right.

"Will my laptop be okay?"

"Show me a screenshot of your configuration first."

"Okay." Nagasaki Asuna licked her lips with her little tongue and clicked the mouse rapidly.

A moment later, the girl sent a screenshot of the Task Manager.

"No, the RAM and video memory are too little." Cheng Fei shook his head.

"So you need to buy a new computer?" Asuna Nagasaki rested her chin on her hand.

"correct."

How much will it cost?

"If you don't want your training speed to be too slow, assembling it yourself would probably cost ten or twenty thousand."

"Wow, it's quite expensive. Did Teacher Cheng Fei buy it himself?"

“I’ll use Lin Xuanqi’s company’s equipment to run it.” Cheng Fei glanced at Shen Xi.

Shen Xi's face was indifferent.

"It's so nice to have a rich girlfriend," Nagasaki Asuna exclaimed.

Cheng Fei thought for a moment, then turned his head without saying a word, "Teacher Shen, to be honest, shouldn't you split this cost with Nana?"

Shen Xi sneered, "You really care about her? Why don't you just pay for it for her?"

“Not at all, Professor Shen. As the department head, it’s not appropriate for you to let your members pay so much money out of their own pockets to complete your research project, is it?” Cheng Fei said, then added, “Of course, as the vice department head, I can also contribute some of the money.”

Nagasaki Asuna rested her chin on her hands, her eyes fixed on the boy's profile.

“You don’t need to pay. I’ll reimburse you for the equipment. Of course, you have to return the equipment to me after you’re done using it.” Shen Xi raised her chin.

"Teacher Shen, I knew you were a good friend." Cheng Fei gave a thumbs up.

"Thank you for your hard work, Shen Xi," Nagasaki Asuna said from the other end of the line.

"Let's choose the configuration now without delay. Since someone's going to reimburse us, let's install a few more RGB fans," Cheng Fei said enthusiastically.

Shen Xi glared at him fiercely, "I'm warning you, I will only reimburse necessary expenses. You'll be responsible for any wasted money."

"Okay, let's forget about the RGB fan." Cheng Fei immediately became honest.

Nagasaki Asuna watched him with a smile, then rested her chin on her hand and thought for a moment, "By the way, Professor Cheng Fei, what should I do if I don't know how to assemble a computer?"

“That’s easy, I can help you pack it.” Cheng Fei rolled up his sleeves.

"Oh, that's great! Cheng Fei, will you come to my house then?" Nagasaki Asuna's voice was filled with surprise.

Shen Xi abruptly raised her head, her piercing gaze fixed on Cheng Fei.

"Well, it doesn't seem appropriate for me to go, but it doesn't seem right if I don't go either." Cheng Fei casually stroked his chin in thought, then turned his head. "How about this, Teacher Shen, you can come with me."

"I refuse, it's a waste of time." The girl's face was full of reluctance.

"Don't be like that, Teacher Shen. As the one who paid for it, it's only natural for you to go and inspect it, right?" Cheng Fei winked at her.

Shen Xi stared at the persuasive boy for two seconds before reluctantly turning her gaze away. "Tsk, what a hassle."

"It's settled then." Cheng Fei punched his fist. "Nana, if you place your order now, everything should arrive by the weekend."

"Then I'll look forward to seeing you two this weekend?" Nagasaki Asuna said with a smile.

……

By the time all the necessary parts for assembling the computer were ordered from Asuna's house in Nagasaki, it was already eleven o'clock.

The girl on the other end of the camera yawned sleepily and said casually, "It seems to be getting late. Isn't Teacher Cheng Fei going home yet?"

"Looks like I have to go. I'll hang up now." Cheng Fei nodded.

“Okay~” Nagasaki Asuna responded softly.

Cheng Fei quickly ended the video call.

Shen Xi raised her head, her face cold. "Your conversation is disgusting me more and more."

"Teacher Shen, that's just how Nana is with people she knows. You've known her for a while now, so don't overthink it," Cheng Fei said seriously.

"Ha, someone familiar." The girl said with a hint of sarcasm.

……

155. Zhou Han didn't want to see Cheng Fei.

"Teacher Shen, I know your feelings for me are twisted, but does that mean I can't even have ordinary female friends?" Cheng Fei helplessly spread his hands.

"First of all, don't talk nonsense. Secondly, it's ridiculous to call someone who's desperately trying to get close to you a normal friend." Shen Xi was very unhappy.

"Teacher Shen, I think you should respect Nana a little more," Cheng Fei said sincerely.

"So you think I'm wrong now?" Shen Xi's eyes sharpened.

"That's not what I meant. It's just that she wasn't desperately trying to get close to me. There are plenty of girls in my class who are much more enthusiastic towards me than she is."

"Sorry, I almost forgot you're a notorious scumbag in Yinghua." Shen Xi sneered.

“Teacher Shen, you’re wrong. I bet there’s no man in the entire Academy City more devoted than me. You’re still so devoted to a super rich and beautiful girl like Lin Xuanqi. You should be moved.”

Shen Xi gritted his teeth, "Then just go ahead and be with your ultimate rich and beautiful girl. She'll definitely be willing to buy you a lot of RGB fans."

“You’re right about that,” Cheng Fei agreed earnestly.

Shen Xi's eyes turned cold.

"But my favorite is still my ultimate cute Moon Princess." Cheng Fei looked her up and down.

"You're starting to have those disgusting fantasies about me again." The girl looked disgusted.

"Teacher Shen, besides that, did you prepare a towel and toothbrush for me?" Cheng Fei changed the subject.

"What nonsense are you spouting now?" Shen Xi instinctively became wary.

"Or I could use yours? I don't mind, but sharing toiletries is never hygienic," Cheng Fei said seriously.

Shen Xi paused for a second, then her expression changed. "I didn't intend for you to stay overnight. Please leave immediately."

"Since we're already here, and we've slept together before, I don't know how to do anything."

"Stop acting crazy here. There were special circumstances before, don't take it for granted."

"Teacher Shen, you are too heartless."

"Who is it that is casually going to the home of a high school girl living alone and refusing to leave, and who is walking closer and closer to the edge of crime?"

That's the general way of putting it, but it makes perfect sense when we're interacting.

"Who's dating you? Enough, Cheng Fei, don't make me angry." The girl's pretty face turned cold.

"Okay, I'm leaving now. I hope you won't be tossing and turning in bed thinking about me later." Cheng Fei raised his hands in surrender. "Well then, goodnight, Teacher Shen."

He packed his things and stepped out the door as the girl watched him go, her expression unreadable.

As soon as Cheng Fei stepped out of the elevator, he received a message from his tea ceremony teacher on WeChat.

"Has Cheng Fei gone home yet?"

Cheng Fei pursed his lips and typed a reply.

"On the Road"

"Even if I wanted to keep her, you wouldn't let me. You're being way too strict."

"So sleepy, goodnight Cheng Fei."

He could almost see the girl yawning incessantly, her head tucked under the covers. After a moment's thought, he started typing.

"Oh, right, there's one more thing."
