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

"I was worried you weren't feeling well just now. I'll definitely hold you tighter next time." The boy let go of her and looked at her expressionless face.

"So Cheng Feiyu is always so brainless. Does one-sided hugging make you feel good?" The girl glanced at him and then turned her face away, her eyebrows furrowed slightly. Suddenly, she got a little annoyed and, feeling resentful, attacked him again with her uniform shoes, this time with more force.

Seeing her displeased expression, the young man couldn't help but laugh, and lowered his head. "I'm sorry, I was out of my mind and didn't understand how hard it was for Your Highness to hug me. I'll respond promptly next time."

The girl's eyes flickered, and she walked forward at a slow and steady pace, her stubborn lips tightly closed.

The boy followed her steps and quietly took her cool, soft little hand.

The girl kept her eyes straight ahead, seemingly oblivious.

The boy then intertwined his fingers with hers.

The girl's face was indifferent, and the movement of her slender legs under her skirt became synchronized with his.

The planetarium is much busier than usual during the summer vacation and weekends, with many children accompanied by their parents or in summer camp groups, their chattering making you feel a real sense of life.

After passing through security and entering the hall, the first thing that caught their eye was a huge glass sphere with a dynamic display of slowly churning flames and sunspots on its surface. According to the description next to it, it was a model of the sun.

"Has Professor Shen ever been to the planetarium before?" Cheng Fei asked casually.

Shen Xi shook her head expressionlessly, her gaze darting around before glancing at him out of the corner of her eye. She raised her chin and said coldly and nonchalantly, "You've been here?"

"No, you know my family's financial situation." The boy shook his head and sighed.

"Then let's watch it together." The girl's tone carried an indescribable undertone.

836. Two people visiting the planetarium

"Teacher Shen, wouldn't it be wonderful if we had known each other since we were little?" The boy said, watching a little boy and girl holding hands walk by.

"Cheng Feiyu's shady criminal fantasies have started again." The girl narrowed her eyes, not without disgust.

"I'm serious, this way we'll definitely be good friends since childhood." The boy looked at her seriously.

The girl glanced at him, still expressionless. "That's true. If you had been disciplined by your parents from a young age, you wouldn't have gone astray like you have now."

"You want to discipline me like a parent from a young age? You really have a strong desire to control me. When I learn about physiology and health in the first year of junior high, will Teacher Shen also personally..." The boy looked at the girl's cold profile.

"Sure enough, I knew the rats in the sewers would only ever think about these filthy things." The girl gritted her teeth and kicked him without any politeness to interrupt him.

The little boy and girl walking in front suddenly turned around and stared intently at the two of them.

After a second of staring at each other, the two children ran away hand in hand.

"Teacher Shen, if you were my childhood sweetheart, I can't even imagine how smoothly our relationship would go," Cheng Fei said, smacking his lips.

Shen Xi narrowed her eyes and sneered, "If you can be so fickle now that you've suddenly appeared out of nowhere, you'd probably be even more likely to abandon your childhood sweetheart after seducing her."

"Teacher Shen, you usually act so serious, how come you actually know your role is that of a newcomer?" The boy asked in surprise and doubt.

"Shut up. Learning this kind of meaningless knowledge was purely accidental." The girl glared at him.

"Are you really planning to cheat and not use your own name?" The boy looked at her with a helpless expression.

"Let's go over there first." The girl ignored him and walked towards a certain area on her own.

The boy had no choice but to follow.

The theme displayed here seemed to be stars. As the two approached, a group of children were gathered around someone who appeared to be a teacher or a tour guide, craning their necks to listen to the explanation.

"Children, there are many types of stars in the universe, some of which are completely different from our Sun. For example, blue giant stars can have masses tens of times that of the Sun and luminosities millions of times greater. This means terrifying electromagnetic radiation. Carbon-based life simply cannot exist in such star systems. However, this also means a much greater energy output than ordinary stars. What do you think would happen if we used solar energy to generate electricity in such star systems...?"

Cheng Fei and Shen Xi stood casually to the side, observing the scale models of different stars. Their outstanding appearance attracted the constant stares of the children who kept turning around to look at them.

The two were used to this situation. After they had seen enough, they continued to walk hand in hand and stopped in front of a starry sky sand table. One of the stars was twinkling regularly, like a lighthouse standing in the night.

“Variable stars are an extremely large family in astronomy, with many different types. Their light variation principles, periods, and amplitudes are all different. There are pulsating variable stars, explosive variable stars, and irregular variable stars, which are intrinsic variable stars, and there are also…” Cheng Fei read the explanatory text on the sign next to him and looked at his side, “Professor Shen, do you think the sun in the binary world might be an intrinsic variable star?”

“Even the most extreme internal variable star wouldn’t extinguish instantly.” Shen Xi shook his head without hesitation, probably having considered this possibility long ago.

"There are also exovariant stars, such as self-variant stars with huge sunspots or bright spots on their surface, or occultations that are obscured by some celestial body." Cheng Fei looked again. "This seems to be something we've been considering?"

The girl touched her chin thoughtfully, then nodded slightly.

The two continued walking forward.

"So, I don't know how Teacher Shen's research has been going these past two days. Has Xiao Yi already compiled a lot of data?" The boy looked at her with a smile.

The girl narrowed her eyes, her face turning displeased, but she still spoke in a cold voice, "We tried many analytical methods on the frequency and length of the sun's extinction in the observation records. It's possible that the records of the two suns were confused, causing interference. We didn't get any particularly significant findings, but there are some details about the changes in brightness that are worth noting."

"Oh? Tell me about it." The boy nodded.

The young girl frowned slightly as she glanced at him, but remained silent.

"Teacher Shen, what kind of expression is that?" The boy leaned forward slightly, getting closer.

"Did this flying fish never ask Isena for a conclusion even once?" the girl asked, seemingly displeased.

"I did ask." The boy nodded frankly. "I just wanted to see Teacher Shen's cute little face and hear her cool voice as she explained it to me personally."

"Cheng Feiyu is so incredibly boring." The girl lowered her head, pinched her brow, and sighed with a sense of pity for his misfortune. "Fine, let me just repeat the conclusion for you again. Through mathematical analysis, we can believe that there is a certain correlation between cold days, warm days, and scorching days. In short, scorching days tend to appear in short bursts, followed by relatively long periods of random cold and warm days. Overall, the frequency of warm days will decrease until the next scorching day bursts, at which point the frequency of warm days will increase significantly and then slowly decrease again, repeating the cycle."

The boy nodded to indicate that he understood. "What is your opinion on this, Teacher Shen?"

"What's Cheng Feiyu's opinion? Are you perhaps thinking of asking first because you're not thinking straight?" The girl's sarcastic words abruptly stopped mid-sentence. She opened her mouth, her brows furrowing in a troubled expression, as if desperately trying to avoid using self-reference. Ultimately, she was powerless to resist. Her eyes flickered, and she turned her face away, her strained voice becoming barely audible, "Ask the little cutie for her thought process before copying it..."

The boy smiled at her, but after being glared at with murderous eyes, he quickly straightened up and coughed. "Alright, I'll go first. Based on this discovery, it seems more likely to be some kind of external variable star. Consider the so-called eclipsing binary, which is two stars eclipsing each other. In some extreme cases, it might cause this delicate result of a binary world."

The girl stared at the science exhibit not far away and said coldly, "Cheng Feiyu is somewhat intelligent, but even if the brightness changes, the existing theories still have a hard time explaining the situation of it completely going out."

“That’s right.” The boy smacked his lips.

The two, their fingers intertwined, chatted and strolled through the planetarium, appearing on the surface no different from an intimate couple.

Around noon, Cheng Fei lazily yawned, "Teacher Shen, how about we stop here? There's an astronaut experience restaurant here, it looks pretty interesting..."

"Shut up, you're always just a lazy, gluttonous aquatic mammal." Shen Xi interrupted him without any politeness, raising her chin and looking straight ahead, her tone leaving no room for argument, "The last area is just ahead."

"Yes, it's always Teacher Shen, who has a strong thirst for knowledge." The boy pursed his lips and lowered his head obediently.

The last area of ​​the planetarium is themed around scientific imagination, or science fiction, showcasing things like space elevators and photon sail spaceships.

“Dyson sphere…” Cheng Fei stopped in front of a model of the sun encased in a sphere and rubbed his chin.

Shen Xi glanced at him, puzzled, "What's wrong?"

"Teacher Shen, do you Protoss build Dyson spheres?" the boy asked her.

The girl hesitated for a moment, then her expression turned serious. "Using stars as a long-term, stable energy source is indeed a good choice. Do you think the dual-body world is related to Dyson spheres?"

"Just kidding. But if you really think about it, if there were Dyson sphere twins, they wouldn't even be able to see the sun, right? Let alone two of them." The boy shrugged.

The girl touched her chin, lost in thought, then shook her head. "We can't rule out that possibility, but the binary system is an unstable factor. Star Spirits travel through different dimensions and have countless stars to choose from. Unless the binary world has some unique advantage, it's unlikely to be chosen."

"How about this reasoning: if two suns are built together as a Dyson sphere, they can share the associated power transmission facilities?" The boy snapped his fingers.

"Do you think a civilization capable of building Dyson spheres across dimensions would care about something like this?" The girl was looking up at him, but her eyes held a strange, condescending pity.

“That makes sense.” The boy nodded nonchalantly, then paused. “Actually, rather than a Dyson sphere that makes the sun disappear, I’d like to ask you Protoss people if you ever get bored and build a shield to cover other people’s suns, and then turn it on and off occasionally.”

As Cheng Fei spoke, he released Shen Xi's small hand and began to gesture with great interest.

The girl looked at him speechlessly. "What's the point?"

"Of course it's fun, like a person teasing an ant." The boy said seriously, his hands in his pockets.

"The only person in the entire universe who knows Cheng Feiyu has such lowbrow tastes is Cheng Feiyu." The girl said with disdain, glancing at his arm without making it obvious.

"Just kidding, but I think if we really can't find the operating rules of the dual-body world, we can indeed consider human factors. Maybe it was an avalanche that caused it all. What do you think, Teacher Shen?" The boy seemed oblivious to her gaze, keeping his hands in his pockets.

"It's possible to break out of the existing framework. Cheng Feiyu did have some sense this time, although it's more likely that he would choose to attribute everything to some special, unrelated entity when faced with a problem and then comfortably give up thinking about it." The girl turned her face away and chuckled, then glanced at his arm out of the corner of her eye.

"Teacher Shen's mouth is still so sharp." The boy sighed, then followed her gaze and smiled with interest. "You're not wondering why I haven't held your hand yet, are you?"

The girl's face turned cold in an instant. She gritted her teeth and glared at him. "Cheng Feiyu, stop being so presumptuous. If you don't want to hold my hand, then don't."

As soon as he finished speaking, he narrowed his eyes, turned around, and walked away, his displeased expression as if there was something hateful ahead of him.

"If you like holding hands, you can be more frank about it?" The boy quickly caught up and took her soft, comfortable hand in his.

The girl didn't resist. After a second of silence, she took a deep breath, suddenly stopped, lifted her uniform shoe and struck him with an angry gesture, then continued walking forward, gritting her teeth. "Always greedy trash. I don't know how much more honest I can be now that things are like this."

While her tone was fierce, her little hands didn't move at all.

The boy tilted his head to observe her profile, smiled and nodded, "That's true, Ms. Shen is even more impressive than Dyson Sphere today."

"I don't understand, what kind of nonsensical nonsense is this?" The girl glanced at him, her brows furrowing slightly.

“I mean in terms of science fiction,” the boy continued to smile.

The girl stared ahead, took a deep breath, or rather, sighed, her stubborn lips tightly pressed together, ignoring him.

"Is Teacher Shen being silenced?" The boy peered into her line of sight.

"I'm hungry, I don't want to waste time talking." The girl walked forward expressionlessly, looking like a girlfriend pulling her boyfriend along from an observer's perspective.

"Okay, but please come this way to have your meal?" The boy pointed to the side.

The girl looked up at the hanging road sign, her expression unchanged, and walked in the right direction.

……

The two sat down in a corner of the noisy restaurant, which was filled with children.

When the so-called astronaut meal was served, they realized they had been tricked.

"Is this actually pre-prepared food in a bag?" Cheng Fei manually poured the strange, blocky food into a plate.

Shen Xi looked at it, and with a hesitant feeling, picked up the sweet and sour pork that didn't look like sweet and sour pork at all. First, she sniffed it with her small nostrils twitching, then took a small bite and chewed it, her tightly furrowed brows relaxing.

After watching her nimble, animal-like eating process, the boy also ate some, and breathed a slight sigh of relief, "Luckily, it tastes pretty good."

The girl began to eat without saying a word, her pink lips slightly parted, her soft, white cheeks bulging slightly as she chewed.

The boy watched her eat as if nothing was wrong.

"Disgusting." The girl glanced at him and gave him a symbolic blow under the table.

"It's all because Teacher Shen is so adorable." The boy said matter-of-factly, then paused, "Speaking of Teacher Shen..."

"Shut up." The girl said without hesitation.

"I haven't said anything yet?" the boy asked in surprise.

"I could tell from that tone that it's going to be another boring and disgusting topic." The girl's decisive tone was like that of a laboratory administrator who knew the habits of the white mice in the glass box like the back of his hand.

"Her Majesty's hair is incredibly intelligent." The young man looked at her thick, long hair, paused, and then said, "Actually, I wanted to remind Teacher Shen of something."

The girl paused for a second, then spoke with a forced tone, "What is it?"

"Since entering the planetarium, except at the very beginning, when Teacher Shen spoke so much, he never once used his self-reference," the boy recalled, rubbing his chin.

"If you don't need it, then you don't need it. What's the problem?" The girl lowered her head to eat, not looking at him, and spoke quickly without any fluctuation in her expression.

"That's too deliberate. You wouldn't normally go to such lengths, would you?"

“There was no need to refer to myself during this time. That’s just the way it is. What does Cheng Feiyu want?” The girl paused, looked up at him, and her small face carried an air of superiority that left no room for argument.

"I just think you're cheating," the boy said softly but firmly.

"I really don't understand why a mere self-proclaimed title would interest Cheng Feiyu to this extent?" The girl stared at him, her brows furrowed, revealing a serious expression of bewilderment.

"You can't understand it, so why are you using it against me?" the boy said calmly.

The girl subtly turned her face away, remained silent for a short while, then lowered her head to eat, refusing to look at him again.

"Are you escaping reality?" the boy observed her.

The girl stared at the food on the plate, her eyes flickering as if she were torn between two conflicting thoughts. After a moment, she let out a helpless sigh, "Never mind, never mind..."

837. A Date for Two in the Afternoon

"Forget it?" Cheng Fei looked at Shen Xi.

Under the boy's gaze, she turned her face away, her uneasy eyes scanning the surroundings. Her voice became hesitant and barely audible again, "Trash, wait until tonight... Little Cutie will satisfy you. Even if you're impatient, give it to her. Behave yourself, Little Cutie. There are so many people outside. It's already embarrassing enough that she said it once in a while..."
