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

"You're playing tricks on me again. Do you think I'd believe you, you fickle Cheng Feiyu?" Shen Xi glanced at the boy nervously playing with his hair, then continued to glare at him. "And even if you really like me, it doesn't change the fact that you're always trying to disgust me."

"You're just being stubborn, cutie. You clearly enjoyed our date, but you're pretending to be reluctant. That's so tsundere."

"I can't take it anymore, I want to go back, Cheng Fei, let me go!" The girl took a deep breath, her pure eyes became empty, and she broke free from his embrace.

336. Cheng Fei was just explaining.

The boy quickly pulled her back into his arms. "I was wrong, Ms. Shen. Forget what I said. Please, even if you feel like throwing up, please bear with it and go on a date with me. I really feel that my life is bleak and meaningless if I can't have you."

"You piece of trash, then stop spouting your absurd fantasies at me. I've already barely tolerated you, Cheng Feiyu, who has touched me countless times, hugging me as you please. Don't push your luck and continue to verbally harass me." Shen Xi was so angry that she kicked him twice.

"Okay, don't be angry, let's keep going." The boy put his arm around her slender body and led her forward. "But we should talk about something along the way."

"Is there nothing else in the brains of aquatic mammals besides endless filthy thoughts? Please at least talk to me about something serious to distract me, that would make me feel better." The girl glared at him.

“Okay, then let me tell you about the dexterity hand solution that Xiao Yi and I designed.” The boy said seriously, then looked at her. “Teacher Shen, could you please not be so tense? If you can, relax a little and lean against me, like that girl over there?”

Following his finger, not far away, a college couple was being very intimate. The way the girl was clinging softly to her boyfriend was reminiscent of Asuna Nagasaki.

"I'm sorry, I can't be that shameless." Shen Xi said coldly, and with a feeling of extreme reluctance, she relaxed her body slightly and leaned into the boy's arms, transforming from a "sulking girlfriend" into a "cold girlfriend".

"Okay, this is cute too." Cheng Fei nodded, pulling her closer to make them even more intimate. "What were we talking about earlier? Oh right, dexterous hands. Teacher Shen, do you know what dexterous hands are?"

"It's just a hand?" The girl frowned.

"It's definitely a hand. Can I borrow your cute little hand for a moment, please?" The boy opened his palm to her.

The girl stared at his face, her delicate brows furrowing slightly.

"Teacher Shen, what's with that expression? First of all, your hand is mine today. Secondly, I'm doing this to make it easier to explain. This is important, so please cooperate." The boy said earnestly.

"I hope he's not trying to trick me again to satisfy his own dirty desires that can't be seen in the light of day." Shen Xi placed her cool, soft little hand in the boy's palm without expression, and then it was held. Feeling the heat transmitted from his body, her eyes flickered.

"Why would I lie to you? Listen to me. As we all know, most bodily functions are in the upper body, and most of the functions of the upper body are in the hands." The boy took the girl's small hand and kneaded the soft pink pads of her palm and the base of her fingers.

Shen Xi narrowed her eyes as she watched the boy's actions towards her.

The boy flipped her delicate little hand over. "Look, apart from the thumb, each finger has two joints, each of which counts as one degree of freedom. The base of the fingers can move forward and backward and left and right, which is two degrees of freedom. Add the thumb and wrist, and a human hand has twenty-three degrees of freedom."

"If the birth of human intelligence relies on the brain, then its realization relies on the hands. It can be said that the human hand is the most exquisite tool in the history of the earth, the pinnacle of natural evolution. And the bionic mechanical hand made by imitating such a human hand is the so-called dexterous hand. Do you understand, little cutie?"

Shen Xi squinted and remained silent for a second, then looked up with a chill, "So why did you keep squeezing my hand while you were talking? Especially touching between my fingers, it felt so disgusting."

"I'm sorry, little cutie, I've actually wanted to do this for a long time. I finally found the opportunity. Your hands are indeed small and soft, and feel wonderful." The young man sighed softly, as if some wish had been fulfilled.

"As expected, trash!" The girl slapped him with her uniform shoe and tucked her hand into her sleeve.

"Teacher Shen, you can only blame yourself for being too good-looking. You're attractive from head to toe."

"Starting to talk about disgusting topics again?" The girl's eyes narrowed.

"Sorry, but please keep giving me your hand. Please bear with it, as this is part of the agreement. Let's continue."

The boy opened his palm.

The girl took a deep breath, frowned, and put her small hand back.

“Okay, so in order to achieve such dexterity under Earth’s technological conditions, Xiao Yi and I have prepared the following plan.” Cheng Fei said, holding the girl’s fair and slender wrist with one hand and unbuttoning her cuffs with the other.

"Cheng Fei! What do you want now?" Shen Xi's expression changed.

The boy paused, and said in a very sincere tone, "Teacher Shen, please don't get excited. I just need to borrow your wrist and forearm to give you a signal. It's really not something strange, please don't mind."

"I can barely manage, but if you dare to do anything reckless, I'll go back immediately," the girl said coldly, her brows furrowed.

"Okay." The young man calmly untied her cuffs, rolled up her sleeves, revealing her excessively white and slender arms.

The boy grasped her arm. “There’s a fact that might seem counterintuitive: there are no muscles in a person’s fingers. The strength of the fingers actually comes from the forearm. There are flexor and extensor muscles on the front and back of the forearm. The tendons of the flexor and extensor muscles are like the string of a pull-string toy, passing through the carpal tunnel in the wrist and connecting to each fingertip, pulling the fingers to bend and open.”

As Cheng Fei spoke, he ran his fingers along Shen Xi's arm, from her wrist to her fingertips.

The subtle touch made the girl tremble almost imperceptibly. She narrowed her eyes and stared intently at the boy's movements, wary of him doing anything out of line.

"Look closely, as long as the brain sends the command to move the fingers, the muscles in the forearm will contract, pulling the fingers under the skin through these tendons." The boy even rolled up his sleeves to demonstrate to the girl.

Compared to Shen Xi's soft, delicate hands that lacked sharp edges, the boy's hands appeared stronger and more powerful, with clearly defined veins.

"Of course, there are also some muscles in the palm to assist in the movement. It is in this way that the human hand can achieve both precise control and power output in a small space." Cheng Fei helped her pull the sleeve back to its original position and button it up.

"So?" Shen Xi relaxed a little, then frowned and asked.

"So our solution is to mimic this drive system, installing servo motors inside the robot's arm to replace muscles, using tendon ligaments to connect to each finger instead of tendons, and then using flexible sensors to detect the angle, pressure, temperature, and humidity of the fingers instead of skin. By summarizing all the data and relying on the algorithm written by Xiao Yi, we can achieve a perfect replication of the human hand." The boy said, revealing a proud expression.

"Is it really possible?" Shen Xi pondered for a moment.

"It's difficult, but it's surmountable. There are other companies on Earth trying this, but we're far ahead." The young man put his arm around her shoulder, his tone full of confidence.

"Heh, anyway, it's all about relying on Isena." The girl remained motionless.

"Don't mention it. Everyone can understand these things when they're explained, but actually implementing them requires a lot of professional knowledge. I'm sick of reading these materials lately. There's no one in the entire Academy City who works harder than me." The boy shook his head and sighed.

337. Real Technology Co., Ltd. offers excellent benefits.

"I can't see where the guy who drives luxury cars and treats girls to meals is working hard. Oh right, he's working hard to date rich girls." Shen Xi sneered.

"Teacher Shen, I go to bed at 2 a.m. and get up at 6:30 a.m. every day. Interacting with girls only takes up a small part of my life. I didn't expect you to be so unaware of me." The boy shook his head and sighed.

The girl glanced at his face, then looked away, raising her chin to gaze ahead. "I hope so. So why did you bring me to the Academy of Science and Technology?"

"I got the tendon rope. Professor Ruan helped me contact the materials science department here. They have a high-performance polymer fiber. Oh, by the way, Professor Ruan is the founder of Rongchuan Electromechanical. I chose the motor he designed." The boy said seriously.

"After all that, it's just a patchwork of different things," the girl scoffed.

"Teacher Shen, don't you think that figuring out how to put these things together is a skill in itself? The era of genius inventors working alone is long gone. Modern engineering relies on the collective wisdom and efforts of technical experts."

"Maybe, as long as they don't try to take advantage of the situation." The girl said indifferently.

"Sweetie, if you keep questioning me like this, I'm going to do something really bad to you."

"Cheng Fei, I'm warning you, don't do anything reckless!"

……

As they walked and talked, they arrived at a corner of the science and engineering campus, where a tall, square-shaped building stood.

Shen Xi frowned as she looked at the plaque on the gate: "Polymer Molecular Engineering Laboratory..."

"Sweetie, stay here and don't move."

After Cheng Fei finished speaking, he strode towards a well-mannered young man in a plaid shirt with glasses and dark circles under his eyes.

"Is it Dr. Wang Yang?"

"you are?"

"Cheng Fei, Professor Ruan introduced me here." The young man extended his hand to the other party.

"President Cheng? It's a pleasure to meet you. No wonder Professor Ruan said you were so promising at such a young age." The young man named Wang Yang shook hands with Cheng Fei, curiously examining the excessively young face in front of him.

"You flatter me. Shall we look at the samples first?"

"This is all we have right now; the production is far too small." Wang Yang handed a package of white thread to Cheng Fei.

"Can I take it out and look at it?"

"of course."

Cheng Fei opened the sample bag, pulled out a section and tugged at it. Apart from a slight elasticity, it looked no different from ordinary materials.

“I’ve included an explanation of the features inside.” Wang Yang watched his movements and adjusted his glasses.

"I've seen the electronic version." Cheng Fei paused. "Professor Ruan mentioned that there are difficulties in mass-producing this material?"

“Yes, currently, the problem with the tough fiber is that the copolymerization catalytic efficiency is too low. The stannous octoate I used is not heat-resistant. I’ve tried many other ligands, such as triphenylphosphine, but they cause some segments to crosslink prematurely…” Wang Yang said while thinking.

Cheng Fei looked at him.

"Sorry, I tend to get distracted when I talk about research," Wang Yang said, snapping back to reality.

"It's alright, so are you still planning to continue researching tough fibers? I heard you've been working on this project for several years." Cheng Fei said calmly.

"Well... to be honest, my doctoral dissertation is almost finished, and I'll graduate this year if all goes well. My supervisor has no hope for the mass production of tough fibers, so the research has stopped. Actually, I have some ideas, but without a lab and funding, I can't continue." Wang Yang sighed and then cast a subtle glance at Cheng Fei.

"Professor Ruan introduced it to you, right? I'll be frank, I'm interested in this. If you're willing to join our company, I can sponsor your continued research on tough fibers." Cheng Fei handed him his business card.

“Real Technology Co., Ltd…” Wang Yang frowned and looked at it. “What do you do?”

"Our company is still in its early stages of making humanoid robots, so you may not have heard of it. However, the benefits are excellent, and the workplace is located in Academy City," Cheng Fei said seriously.

"Well... Mr. Cheng, I'll think about it when I get back." Wang Yang stared at the business card for a moment, a hint of doubt flashing in his eyes.

“Of course, no problem.” Cheng Fei looked at his face.

"Okay, we'll keep in touch later." Wang Yang put away the business card.

"Dr. Wang," the young man said, his hands in his pockets, suddenly looking into the distance.

A cool, aloof girl with long, dark hair stood in front of the green belt, observing something; her back was slender.

"What's wrong?" Wang Yang, who was about to leave, turned around.

What is the typical annual salary for a materials science PhD graduate?

Wang Yang was taken aback. "Well, currently... it's between 400,000 and 700,000. The range in our industry is quite large, depending on the specific company."

"I'll spend one million to get the tough fiber into mass production as soon as possible."

As the boy finished speaking casually, the air fell into a deathly silence.

Wang Yang frowned and clenched his fists.

He strode forward, grabbed the boy's hand, and asked with a firm gaze, "Mr. Cheng, where will I work tomorrow?"

……

The boys and girls left the science and engineering school.

“Some people don’t value money anymore. They casually offer a million-dollar annual salary to research some random material, not even counting the cost of buying a patent.” Shen Xi let Cheng Fei put his arm around her shoulder and sneered.

"Teacher Shen, this tough fiber is no ordinary material." The boy picked up the material bag and shook it.

"Is that so?" the girl asked expressionlessly.

“Listen to me, there aren’t many materials in this world that can rival biological tendons. Let me give you a few examples: Kevlar has very high tensile strength, but it’s not flexible enough; carbon fiber is too brittle; and various metals are even worse, they’re too heavy.” The boy shook his head. “If I hadn’t happened to hear about this tough fiber, I would have been planning to study composite materials.”

"Then how will you solve the problem of mass production?" The girl frowned slightly.

"Thanks to Dr. Wang," the boy shrugged.

"He hasn't figured it out in several years, what if it's simply impossible to achieve?"

"Materials science is a kind of metaphysics. As long as there is a direction, Xiao Yi can use computing power to simulate and brute-force screen the synthesis path to quickly advance his research."

"The premise is that he himself is smart enough and has not gone in the wrong direction."

"Don't worry, I'm not wasting money. I've already looked into his resume."

"That was a very thorough and watertight explanation."

"It's watertight. Sigh, it seems only those of us with such sharp minds are a perfect match in this world." The boy shook his head and sighed.

"Here we go again. There's no one here who's a good match for you." Shen Xi glared at him.

"Teacher Shen, are you unhappy?"

"What are you trying to say?"

"Now, let's be intimate like any other couple." The boy put his arm around her shoulder and tightened it slightly.

"Nobody here is your partner. This is such a lame excuse that never ends." Shen Xi glared at him fiercely.

"That's really impeccable." The boy pouted. "But are you really not happy?"

"I'm sorry, I just feel disgusted right now. I really regret being crazy last night and agreeing to change the agreement."

Is this the second most regrettable regret in history?
