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

"Nana, are you smoking meat?" The boy stepped forward and observed the pink-haired girl squatting beside the smoky fire.

"No, cough cough... Shen Xi asked me to make this." Nagasaki Asuna turned around, her eyes watering from the smoke, and carefully handed him a dark object.

Cheng Fei took it and found that it was a piece of glass, the surface of which was covered with a uniform black ash due to smoke.

A cool, aloof girl with long silver hair walked out of the house. "You vixen, are you done yet?"

"That's about it. Is the last piece in Cheng Fei's hands?" Nagasaki Asuna looked at Shen Xi.

"Teacher Shen, isn't it a bit too much to treat Nana like a laborer?" The boy turned around.

The aloof girl glared at him without any politeness, snatched the smoky glass away, and said, "Give it to me and shut up. Scientific research always requires someone to sacrifice. When you go out to fool around, of course your vixen will have to take your place."

"First of all, everyone said they weren't fooling around anymore, and secondly, the so-called 'there always has to be someone' actually meant specifically the two of us?" the boy asked in surprise.

“This is the work that servants should do. If the servants don’t do it, then the servants’ servants should do it. What’s the problem?” Shen Xi checked the condition of the glass and walked into the house.

"Teacher Shen, even if I am your servant, Nana is not. Please don't misunderstand this." Cheng Fei followed her with his hands in his pockets.

“Yes, yes, I’m a pet, not a servant.” Nagasaki Asuna followed the boy with her hands behind her back, nodding quickly.

Shen Xi glanced at the two people behind her out of the corner of her eye, pinched the bridge of her nose and sighed with a sense of pity for their misfortune, without offering any opinion.

"Has Professor Shen found a way to indirectly observe the sun? Or is he planning to rely on a stand-in's retina to withstand ultraviolet radiation?" Cheng Fei asked with great interest.

"So it's the brainless Cheng Feiyu. There's no reason to keep you in suspense about a problem that could be solved with a little thought." Shen Xi scoffed.

"Well, it seems that Teacher Shen's clever little brain has already found a solution. You're truly amazing." The boy smacked his lips.

The three went up to the attic, where Rose was adjusting her binoculars.

Compared to Cheng Fei's last visit, this original telescope has undergone some modifications. The main changes are that a groove for mounting glass plates has been added in front of the objective lens at the head, and a whiteboard for adjusting the distance has been added under the eyepiece at the tail.

Shen Xi climbed onto the shelf, inserted the last piece of frosted glass into the groove, dusted off her hands, and looked at Luo Xi, "Now point the telescope at the sun."

"Right away." Losi immediately adjusted the angle of the telescope's base.

Cheng Fei guessed what the two had talked about while he was away, and now it seemed that Luo Xi was Shen Xi's assistant.

The Celestial Queen possesses a hidden ability that allows her to manipulate others into becoming her subordinates, no matter where she goes, and he is now beginning to doubt this possibility.

"Aimed correctly? Will this really work?" The stargazing girl wearing an oversized wizard's hat looked skeptical.

With the help of the telescope, a blurry bright spot was projected onto the cardboard.

"No doubt about it." Shen Xi began adjusting the distance between the whiteboard and the eyepiece, her small face focused.

Cheng Fei and Nagasaki Asuna watched from the sidelines.

"Is this the projection of the sun?" Nagasaki Asuna blinked, curious.

Cheng Fei nodded seriously, "By projecting sunlight onto a whiteboard through a telescope, as long as the distance is right, you can get a clear, inverted real image of the sun without hurting your eyes. This is the telescope projection method. Astronomers in the Renaissance used this method to observe sunspots."

"The Renaissance... period?" Rose, standing beside him, looked puzzled.

"Don't mind it." The boy glanced at her, remaining expressionless.

"It's one thing to flaunt some well-known nonsense," Shen Xi said with a cold laugh, making no attempt to hide her contempt.

"Did Teacher Shen get it sorted out?" Cheng Fei peeked out to observe.

As expected, the sun's projection appeared on the whiteboard as a bright, well-defined circular spot.

“Now all we need to do is observe and record.” Shen Xi nodded slightly with satisfaction, staring at the projection on the whiteboard, then suddenly frowned slightly, “What’s going on…”

"What's wrong?" Cheng Fei asked, looking at her delicate face, which seemed to be deep in thought.

“The sunspots on this sun are so strange,” Shen Xi said, rubbing her chin.

Nagasaki Asuna leaned forward, her upper body close to hers, "Feels much better?"

In the sun projection on the whiteboard, numerous dark spots are randomly scattered, as if a handful of black sesame seeds have been sprinkled on the surface of a perfect omelet.

"What does Teacher Shen think?" Cheng Fei rubbed his chin, the scene before him was quite different from the sunspots he remembered.

"I don't know, maybe this is just how the sun is." Shen Xi frowned and shook her head.

"Is there a problem?" Luo Xi looked at the three of them, looking bewildered.

"It's nothing, it's just that it's not quite the normal sun we're used to," Cheng Fei shrugged at her.

“What should a normal sun look like?” Rose was even more confused.

"Let's observe for a while and see." Shen Xi shook her head.

So the four of them began to observe the sun's projection.

In theory, they can use Isena to capture video signals without having to painstakingly hand-draw them like ancient astronomers. They only need to manually calibrate the telescope angle, a task that is currently being handled by Roche.

The stargazing girl sat obediently on the bench, carefully recording the appearance of the sun on her manuscript. This was her first time doing this, so she was very engrossed.

"Teacher Shen, since there's nothing urgent, how about we stop here? After all, we can't go without rest. We can come back tomorrow for our shift observations." Cheng Fei thought for a moment and then said seriously.

"Trash, come out with me tomorrow morning." Shen Xi didn't object, but kicked him.

"Does this mean you want to go on a date? Teacher Shen, it's only been a few days, and you're already being too clingy?" The boy asked, puzzled.

“Cheng Feiyu is just a dreamer. Nobody here wants to go on a date with you. Tomorrow you’re going to buy a telescope.” Shen Xi said with a look of disgust.

Why buy a telescope?

The girl's disgust intensified. "You didn't even think of that? Of course, we should observe the sun using the same method on Earth. After all, seeing is believing. Maybe we'll discover something by looking at a normal projection of the sun."

"I see, as expected of Professor Shen, always so meticulous in your research." Cheng Fei nodded in understanding. "But this doesn't conflict with going on a date..."

"Shut up. I told you no one wants to go on a date with you, even if it's a vixen." Shen Xi kicked him to interrupt, then raised her chin to look to the side.

"Huh?" Nagasaki Asuna paused for a moment, then smiled and nodded. "Okay~"

"I see, it was a three-person date." Cheng Fei breathed a sigh of relief.

Shen Xi slapped her forehead, biting her lip, feeling annoyed but unable to vent her frustration.

Luo Xi sat on the bench watching the three of them, hesitated for a moment but still didn't comment.

……

The next morning, Cheng Fei went to the garage across the street and drove the GLS to the downstairs of the upscale apartment building.

Soon, Shen Xi and Nagasaki Asuna, dressed casually, appeared and got into the back seat one after the other.

"Good morning, you two." The boy glanced at them through the rearview mirror.

"Good morning, Cheng Fei~" Nagasaki Asuna responded sweetly.

Shen Xi took a deep breath, her eyes narrowed slightly, and her tone was icy, "You vixen, if you don't let go, don't blame me for being impolite."

"He's really fierce, alright." Nagasaki Asuna puffed out one cheek and obediently let go of the arm she had taken when getting on the bus.

Cheng Fei started the engine and said casually, "Why does it feel like the two of you have gotten along better?"

"Your imagination." Shen Xi's face was cold, and she said without hesitation.

"It means my favorability rating has increased." Nagasaki Asuna nodded vigorously with a happy expression, looking very confident.

This made the young man driving raise an eyebrow.

The three set off as planned to buy a telescope, but instead of a proper optical equipment store, they went to the antique district of Academy City under Shen Xi's direction.

"To best reflect the situation there, the worse the image quality, the better," was my explanation.

The three of them visited several antique shops before finally choosing an old-fashioned telescope that was said to be over a hundred years old. Apart from its poor performance, it was in perfect working order. After Nagasaki Asuna confirmed that the shop owner was not lying, Cheng Fei spent some time negotiating and managed to get the price down to 88,000 yen.

Although for them now, a few tens of thousands more or less doesn't seem to matter much.

After loading the antiques they had found into the trunk, the three of them purchased the remaining tools needed for observation and returned the way they came.

Back on the 36th floor of the upscale apartment, Shen Xi set up the telescope on the balcony, pointed it at the sun, and attached a modern filter to weaken the sunlight.

The aloof girl stared at the projection on the whiteboard, rubbing her chin thoughtfully. "Sure enough, a normal sun wouldn't have so many sunspots at the same time."

"So what does having too many sunspots mean, my Moon Princess?" the boy asked, looking at her.

“I don’t know, that’s why I’m going to investigate. Cheng Feiyu will stay here to observe, and the fox spirit will go to the dual-body world to observe.” Shen Xi gave the order with an air of absolute authority.

"Huh? Me?" The boy was stunned.

"Otherwise?" The aloof girl stared at him, her face turning displeased. "Or are you going off somewhere to fool around again?"

"Not at all, it's just that I think Professor Shen can observe and study at the same time, while I still have my own work to do..." the boy said seriously.

"It's fine if you're willing to let me sunbathe here, since I won't get tanned anyway. It's just that you're unwilling to share any of the workload. So this is all you mean by 'always protecting me'?" Shen Xi sneered, turned her face away, narrowed her eyes, and her pretty face became unhappy.

Cheng Fei looked at her and remained silent for a second before honestly lowering his head. "I was wrong, Your Highness. Please be sure to entrust the observation task here to me."

"Wow, she's really good at acting cute!" Nagasaki Asuna widened her eyes slightly and covered her mouth, looking surprised.

"Stop talking nonsense and hurry up." Shen Xi kicked the boy with symbolic force and walked towards the study without expression.

Cheng Fei looked at Nagasaki Asuna and shrugged.

……

As arranged by Shen Xi, the three of them split up.

Cheng Fei spent a day recording normal solar projections on the balcony, Nagasaki Asuna and Rosie did similar work online, while Shen Xi buried herself in research in the study.

In the afternoon, as the boy on the balcony sat idly by with a parasol (provided by Asuna Nagasaki) to keep the telescope pointed at the sun, Shen Xi came out of the study.

The aloof young woman stood expressionless in the living room, gazing at the balcony with her pure, dark eyes for a moment before silently changing her shoes at the entrance and leaving. The sound she made drew a puzzled look from the boy on the other side.

After a while, she reappeared, nervously arranging her canvas shoes neatly, and carrying a small bag, she walked towards the balcony.

"Here you go." The girl's emotionless voice rang in Cheng Fei's ears.

The boy looked up and saw Shen Xi eating a vanilla Cornetto ice cream by herself in one hand, and handing him the same ice cream in the other.

The aloof girl had no expression, her little tongue peeking out from between her pink lips as she licked the ice cream.

Looking at her practiced and seemingly casual manner, Cheng Fei suddenly realized something and asked, "Teacher Shen, you don't mean you're secretly buying ice cream by yourself all the time these days, do you?"

"No." Shen Xi turned her face away subtly, her eyes flickering.

"I'll ask Nana later," the boy said decisively.

"What I mean is that I didn't steal anything. It's my freedom to buy whatever I want to eat. Cheng Feiyu, stop interfering." The girl frowned slightly, kicked him without any politeness, and shook the ice cream she was handing him. Her little face was impatient. "If you don't want to eat it, you can just say so. I won't buy it for you again."

"How could that be? Of course I want to eat what my little cutie bought, and it's so hot." The boy took the item, tore open the top layer of packaging, and took a big bite like a hungry wolf, crunching and chewing, a stark contrast to the girl's slow licking.

Shen Xi stared down at his actions, her brows furrowed, revealing an expression of incomprehension and disgust, as if he were burning a zither and boiling a crane.

"Teacher Shen, what are you doing over there again?" The boy noticed her gaze, looked up, and sized her up.

"Nothing, I just find you disgusting. Goodbye." The girl shook her head and turned to leave.

"Why are you disgusting again? By the way, did you buy anything for Nana?" the boy asked, looking at her retreating figure with a puzzled expression.

"Inside the refrigerator," Shen Xi said coldly without turning her head.

851. Cheng Fei met his half-sister again.

In order to obtain enough observation records, the three of them worked on this matter for several days in a row.

Every afternoon, while Cheng Fei stood guard by the telescope under the scorching sun, Shen Xi would quietly go downstairs and bring him and Nagasaki Asuna an ice cream each, though there was reason to suspect that her motive was simply that she wanted to eat it herself.

Incidentally, she always brought matcha flavored ones for Asuna Nagasaki.

a few days later.

Cheng Fei pulled up a chair in the study and sat down, letting out an exaggerated sigh of relief. "Your Majesty, is that enough? I'm really going to die from the sun in a few more days."

Although his skin color did not change at all, it was unclear whether it was due to the effectiveness of Nagasaki Asuna's parasol or the passive skill of Extraordinary Charm.

"It wouldn't be bad if they died from sunburnt to the point of becoming dried fish that can't run away." Shen Xi stared at the sun projection photo on the screen and sneered.

"Teacher Shen, please don't do this, it's too perverted." The boy shook his head.

"So, what did you find?" Nagasaki Asuna licked a matcha-flavored Cornetto ice cream that she had just taken out of the refrigerator. The girl would occasionally take a small bite while licking, and her way of eating was somewhere between the other two.

"First, one thing is confirmed." Shen Xi stared at the large number of photos, "The dual-body world does indeed have two suns, at least."

Cheng Fei nodded seriously, "Okay, shall we tell you something else that no one knows?"
