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

"Go on," Tang Yu said, gazing intently at him.

"Therefore, I don't think this is a natural phenomenon at all. Since the abnormal sun is man-made, the normal sun may have been tampered with as well. Suppose we wrap the entire star in a giant structure like a Dyson sphere. This Dyson sphere is made up of a large number of small, sheet-like units. As long as we control the opening and closing of these units in sync, we can instantly turn the sun on and off, just like a Venetian blind." The boy gestured.

"That's impossible. Did you observe the so-called Venetian blinds?" Tang Yu narrowed his eyes.

Cheng Fei shook his head, his tone resolute, "No, but not because they don't exist. It's because those units are too small. Even if each solar panel is tens of meters in diameter and the size of a football field, at such a great distance between the Earth and the Sun, the resolution of this world's telescope is still insufficient to see them."

"Even so, that only explains the extinction of a normal sun. What about an abnormal sun?" Tang Yu remained noncommittal.

“It’s even simpler. The surface of the anomalous sun is covered with a large number of light-emitting units. Just switch these units on and off synchronously.” Cheng Fei shrugged.

"What makes you so sure? Even if the so-called blinds on a star are unobservable due to distance, do you think these luminous units on a satellite are also invisible? They should be very obvious at close range, right?" Tang Yu spoke quickly.

“Actually, I’ve already observed them.” The boy said casually, “They are those randomly distributed patchy black dots. I guess they are all broken light-emitting units that have been neglected for a long time. As for other facilities, since those black dots don’t move, it is clear that the satellites of the binary star are tidally locked, and there are more things that can be hidden on the back of the satellites.”

Tang Yu did not speak immediately, but stared at him expressionlessly, as if making a silent question.

"The sun of the binary star is a massive blue giant with a considerable energy output. Transforming the satellite into an artificial sun might be a way to compensate for the impact of mining stellar energy on the binary star, after all, this is a planet where civilization exists." The boy softened his tone. "In addition, under normal circumstances, to avoid the binary star being scorched by two suns simultaneously, the opening windows of the artificial sun and the Dyson sphere are staggered, so normally only one sun is visible. However, this system is malfunctioning now, causing the binary star to frequently fall into a polar night without a sun."

After he finished speaking, the air in the wasteland became quiet, and even the sound of the wind blowing across the earth became unusually clear.

Cheng Fei breathed a sigh of relief and looked at Tang Yu with a relaxed expression. "This is the only explanation I can come up with based on the phenomena I've observed. I think even if there are some errors, it shouldn't be too far from the truth, right?"

Tang Yu's gaze turned serious as she looked at him, and she opened her mouth as if she wanted to say something.

At this moment, the world, which had been shrouded in twilight, brightened at a visible speed, and unprecedentedly intense sunlight poured down from the sky, flooding the earth like a torrent.

The two of them simultaneously noticed something was amiss and shaded their eyes with their hands, looking up at the sky.

Suddenly, two blinding suns appeared in the sky, and the weather became even more terrifying than scorching daytime.

Under the scorching heat of two suns, everything heated up rapidly, as if being put into an oven. Just being exposed to the sunlight gave one a suffocating dizziness, and an unsettling buzzing sound came from the ears.

In the distance, in the town of Radiant Light, one can vaguely see figures fleeing.

Cold sweat broke out on both of their foreheads at the same time, and they exchanged a glance.

Before the intense heat of the two days could fully descend, the two disappeared from the teleportation platform.

……

The 36th floor of a high-end apartment building on Guang'an Street.

After solving the mystery, Cheng Fei, Shen Xi, and Nagasaki Asuna sat down for breakfast together. This was the first time the three of them had met after several busy days.

"Mr. Cheng, I must admit that your conclusion is brilliant, even closer to the truth than most people. Congratulations on opening the door to Deep Blue. Someone will assist you in completing the necessary procedures to join the foundation."

The boy received this message on WeChat.

"So Cheng Fei succeeded? Congratulations~" Nagasaki Asuna clapped her hands slightly.

"Probably, though I don't know what will happen next." The boy shrugged, pressing the cut fried dough sticks into the soy milk to soak until they absorbed the soy milk and softened, then he lowered his head and put them in his mouth.

"He actually joined Deep Blue. Cheng Feiyu can finally betray us as he wished." Shen Xi, who was blowing on the eight-treasure porridge to cool it down, sneered, while glancing at the boy's fried dough sticks.

"Not at all. I have always been loyal to Her Majesty the Empress. Although I am indeed very curious whether there is an Empress or something on the other side. If possible, it would be nice to get an official position. After all, I have a year of experience as a regent." The young man stroked his chin seriously.

As soon as she finished speaking, she was mercilessly struck under the table by a soft, delicate foot in a slipper.

“Cheng Feiyu, go if you want. That’s right, maybe other empresses will treat you better, and I can change my governor!” Shen Xi looked away from his fried dough stick and glared at him fiercely.

"Eh, are you angry?" Nagasaki Asuna tilted her head and blinked, not without curiosity.

"You're exaggerating, cutie. I was just saying. I would never do a part-time job outside." The boy tried to reach across the table to touch the cool girl's head, but she nimbly dodged and gave him a warning look.

"You hypocrite, Cheng Feiyu, don't touch me!" The girl became even more ferocious.

"Here'll make it up to you. You've been watching me the whole time, haven't you? Here." The boy picked up a piece of the soaked fried dough stick and put it into the girl's eight-treasure porridge.

The soy milk seeped out naturally and mixed with the eight-treasure porridge.

"You filthy, disgusting trash! What are you doing?!" The girl's pure, ink-black eyes widened slightly, her pupils contracting as if she had seen something outrageous, or as if her purity had been defiled. She gritted her teeth in fury.

"That's quite an exaggerated reaction. Is it really nothing? If you really don't like it, you can scoop it back for me." The boy looked her up and down, his expression one of surprise and uncertainty.

“Shen Xi has OCD, she can’t accept this.” Nagasaki Asuna shook her head with certainty from the side.

"Disgusting aquatic mammals..." Shen Xi looked at the mixture of soy milk and eight-treasure porridge, narrowed her eyes and frowned, as if witnessing some irreversible tragedy. She was silent for a moment, then lowered her head with extreme reluctance, scooped up as much of the fried dough stick and soy milk as possible, and put it in with her small, pink lips slightly parted. Her snow-white cheeks bulged slightly with each chew, and the hatred on her face was so real that it felt like she was sacrificing herself to save everything.

"It's like I poisoned you, but you still ate it, didn't you? You're just so cute." Cheng Fei looked at her, shook his head and sighed.

As a result, he was subjected to a series of chilling kicks under the table, while being pierced by the piercing gaze of someone with something in their mouth.

Nagasaki Asuna tilted her head casually beside her, her bright eyes innocent and naive. "Um, doesn't Nana-chan have one?"

"Of course." The boy immediately picked up a piece of fried dough stick soaked in soy milk and put it directly into the mung bean porridge in front of her.

"Hehehe~" The sweet girl became happy, stirring the two foods together, scooping them up with a spoon to taste, as if it were some kind of delicious food, without any sense of problem.

Shen Xi caught a glimpse of this scene out of the corner of her eye, shivered, her brows furrowed, and her gaze toward the two men grew increasingly disgusted. She silently moved her chair back a little.

"Teacher Shen, stop being so cute over there. By the way, how would you rate my effortless completion of the puzzle of the dual-body world?" the boy said with no small amount of pride.

"It's just a lucky guess, a matter of chance. Anyway, it's just a matter of guessing when the time limit is up." The aloof girl made no attempt to hide her disdain.

"Sigh, fine, I'll let it go if you're deliberately belittling me, but I have all the reasons and evidence."

"I think Cheng Fei's reasoning is pretty impressive. I certainly wouldn't have thought of that much if it were me." Nagasaki Asuna smiled as she looked at the boy.

"A fox spirit with low intelligence can shut up." Shen Xi glared at her, then looked at Cheng Fei. "Besides, your theory further confirms the legend of the Moon Princess. How do you argue now?"

"Teacher Shen, do you really want the title of Moon Princess? It's okay if you don't care. In my heart, you've always been the Moon Princess." The boy looked at her with affection.

Shen Xi's expression changed, and she covered her mouth with a serious expression, "Please stop with your sweet talk. It's even more disgusting than the fried dough sticks from before. If you keep this up, I'm really going to throw up."

866. The endless August has come to an end.

"By the way, Professor Cheng Fei, I have another question." Nagasaki Asuna raised her hand like a student.

"Please speak, Nana," the boy said, looking at her.

“We didn’t notice the moon’s existence before. Since there’s a moon in the dual-body world, why can’t we see it?” The sweet girl tilted her head.

“I guess the light-emitting units covering the surface absorb light when they are turned off, making it difficult to observe,” Cheng Fei said, rubbing his chin. “This also corresponds to the legend.”

"So after all that, we're still just getting closer to that legend." Shen Xi sneered.

"Teacher Shen, I was just about to ask you, the Twin World becoming like this must be the work of the Protoss. What's the point of you pretending not to know all this time?" The boy turned his head.

"Nonsense, how would I know that?" The aloof girl glared at him, and kicked him under the table as she did so.

“I know from the depths of your memories of awakening as the Protoss Queen,” the boy said with certainty.

"That's ridiculous. I haven't had any memories awakened from beginning to end." The girl continued kicking him.

"What exactly is the Protoss's purpose in mining energy in the binary system?" The boy stared intently at her, as if interrogating a suspect.

"I said I didn't know! Cheng Feiyu, dare to question me again?" The girl gritted her teeth, a little annoyed.

"Sigh, if you won't tell me, then so be it."

"I was just about to ask Cheng Feiyu if he found this Dyson sphere theory from somewhere, or if he has some shady secret?" Shen Xi's gaze sharpened, as if she could see right through him.

"Fine, you're turning the tables and questioning my quick wit. Hurry up and eat, Teacher Shen." The boy shook his head nonchalantly and began to enjoy his soy milk and fried dough sticks.

Asuna Nagasaki rested her chin on her hand, remaining silent as her gaze shifted between the two of them. A smile played on her lips as she lowered her head to drink her mung bean porridge.

Shen Xi narrowed her eyes and stared at the boy for a few seconds with displeasure before giving up on asking further questions.

……

"Trash, come online."

"Teacher Shen, the mystery of the dual-body world has only just been solved. I know you're addicted to the internet, but can't you take a break?"

"Ha, summer vacation is almost over, and all I've seen is a staff, not the full set of top-tier equipment you promised me."

"The materials are almost all brushed... Oh well, I spoil you, just a moment."

"Um, I have something to attend to, so I won't be able to keep you two company any longer?"

"It's amazing that this vixen who always treats Cheng Feiyu like the center of her universe would actually say she has something to do."

"Actually, we're preparing a surprise for Cheng Fei, but we need to keep it a secret for now?"

"Is that so? Well, I guess I'll have to wait and see, Nana."

"Hmm~ Cheng Fei will definitely be very happy then."

……

The Academy City, like an endless August, welcomed its last day amidst the incessant chirping of cicadas in the sweltering heat.

Cheng Fei opened his eyes promptly at 6:30 as usual and began his orderly daily life, opening WeChat to send messages at 8:00 sharp.

"Master Ye, I've come to pick you up?"

"No……"

"The tutoring has been cancelled?"

"I'll go there myself..."

"Okay, that's too good."

"I'm just worried that if you drive here, the lady will see you!"

"Master Ye is really cautious; he doesn't seem to care even if he finds out."

"Stop talking nonsense!"

An hour after this conversation, the door to the rented house was knocked on.

Cheng Fei opened the door and saw the familiar obedient girl standing outside, carrying a shoulder bag in both hands.

Her black hair was still tied into neat double ponytails at the back of her head. Her hair was shorter than Lin Xuanqi's, but her temperament was inexplicably more docile. This time, she wore a sailor uniform with apricot yellow as the main color, and her straight legs were still covered with white over-the-knee socks.

"Good morning, Master Ye." The young man opened his arms and smiled at her. "Why are you so late?"

"I had the taxi take a detour." Ye Shuang's gaze met his before she looked away, lowered her head, and walked into the room. She took out disposable slippers from the shoe cabinet, changed out of her spotless brown uniform shoes, and headed towards the bedroom.

"Why do you seem a little unhappy?" Cheng Fei followed her with his hands in his pockets, peering over to examine her beautiful face with its striking features.

Ye Shuang didn't reply immediately. She sat down at the desk, hugged her bag to her chest, and then said in a low voice, "Miss didn't ask me about CPR."

"You didn't ask at all?" the boy asked curiously.

"Hmm." The obedient girl buried her head and bit her lip lightly, looking downcast, lost in thought.

Cheng Fei thought for a moment, "It's better not to ask. There's nothing to be sad about, right?"

"Miss definitely doesn't trust me anymore..." Ye Shuang's voice became even softer.

"There's nothing we can do about it, don't worry about it too much." The young man gently stroked her head.

The girl didn't resist, she just lowered her head and sniffed, "You scumbag, it's all your fault..."

"But maybe she felt too embarrassed, after all, you're like sisters who grew up together, so she simply didn't ask," Cheng Fei said after a moment's thought.

Ye Shuang remained silent.

"Let's start tutoring, school starts tomorrow." The boy shrugged, deciding to skip the topic.

The obedient girl gave a soft "hmm" and opened her bag to take out her study materials.

The tutoring session between the two proceeded as usual; aside from explaining the questions, there was no further conversation, and the entire morning was spent in a quiet atmosphere.

Around noon, Cheng Fei ordered takeout on time to save time, and Ye Shuang closed her workbook and breathed a sigh of relief.

The obedient girl glanced at the boy's face, lowered her head, her eyes flickering, and twisted her small hands together.

She hesitated for a moment, then pretended to get some documents and pulled the shoulder bag next to her into her arms. She secretly took out a comic book from the bottom and looked at it carefully like a student afraid of being discovered by the teacher. Then she turned to the boy and pushed the comic book in front of him, saying, "This."

Cheng Fei caught a glimpse of her movement out of the corner of his eye, put down his phone, and picked up the comic book. "What's this?"

"I'm showing this to you..." The girl's voice sounded inexplicably strained.

"Only one book?" the boy asked, puzzled.

"One book is enough, you're not allowed to read anything else," the obedient girl emphasized quickly, as if she were worried about something.

"Okay?" The boy nodded tentatively. "Although this isn't enough to go with my meal."
