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

Cheng Fei looked at the refreshed text in front of him.

[Nana S Nagasaki Asuna: Check-in duration → 0 days]

As long as Shen Xi doesn't discover Nagasaki Asuna's affair, Cheng Fei can steadily earn points by juggling two relationships.

Although there was a slight mishap with Asuna Nagasaki, Cheng Fei was confident that he could maintain an appropriate distance from her.

Just in case, it's best to make her back down after three months to avoid really hurting her feelings.

Just before going to sleep, Cheng Fei received a message on WeChat.

My friend's nickname is "Tea Ceremony Teacher".

"If Cheng Fei is interested, you can check out my work, but remember to keep it confidential~"

A link to a certain danmaku (bullet screen) website is attached below.

Cheng Fei opened it and glanced at it casually.

"Asuna_Official"

"Japanese singers and voice actors who love Chinese culture~ For business collaborations, please contact..."

She is depicted as a two-dimensional character with long pink hair, and her videos mostly consist of covers of various Chinese songs. She has 43.8 followers.

I randomly clicked on a song, and it was Jay Chou's "Sea of ​​Flowers." The voice was sweet and clear; it was definitely Asuna Nagasaki's voice.

"So that's what you do."

Cheng Fei tossed his phone aside and closed his eyes.

……

On Thursday morning, Cheng Fei was concentrating on doing his homework in the back row of the classroom, the tip of his pen making a soft scratching sound as it slid across the paper.

Chen Hao walked over, full of energy. "I never thought that the second-ranked student in the grade would have to rush to finish homework so early in the morning. Although there was a lot of homework yesterday, how about it, do you want me to lend it to you to copy? Just say the word."

"I'm working on the math problems for the next unit. Have you done them too?" Cheng Fei asked.

"..." Chen Hao froze for a second. "Why did you do this?"

"Preparing for the monthly exam." Cheng Fei looked up and said, emphasizing each word, "I want to get first place in the grade."

"You're despicable."

"I have a reason why I have to win."

"really?"

"real."

"I wish you success." Meeting the boy's resolute gaze, Chen Hao felt a deep respect.

"Thank you."

Yawning, Du Xinhua walked into the classroom, put down her schoolbag, and strolled over to the two of them. "I'm so sleepy, what are you doing?"

Chen Hao glanced at him and said, "We were talking about preparing for the monthly exam."

"Preparing for the exam now is too extreme. The last monthly exam was still the last one." Du Xinhua yawned again.

"Hey, how late are you going to finish applying the glue?" Chen Hao asked, looking at him.

"No, I'm just playing a new visual novel."

"They even said they weren't applying glue."

"Does playing visual novels require using glue? That's prejudiced."

"Hypocrisy, isn't it better to be honest like me?"

"So you did hit him."

“That’s right, I saw it yesterday—never mind, we can talk about it later.” Chen Hao’s voice was quite loud, but he stopped abruptly when two girls walked in through the back door and sat down.

Cheng Fei put down his pen and looked at the two of them. "By the way, do you know how the speed of light was measured in history?"

The two looked at each other in bewilderment.

"I don't know, how was it measured?" Du Xinhua said.

"Initially, astronomer Romer used the disappearance and reappearance phenomenon of Io to calculate the order of magnitude of the speed of light. Later, Fizeau designed an experiment that used a high-speed rotating gear, a set of mirrors, and a light source to measure the speed of light. Later still, Michelson improved this experiment..."

Ten minutes later, a young English teacher strode into the classroom, interrupting the three's discussion on the history of physics.

……

In the afternoon, Cheng Fei walked out of the classroom through the back door, intending to go to the club activity room, and immediately spotted Shen Xi looking at the scenery in the corridor.

A beautiful girl with long, dark hair and a slender figure captivated all eyes.

"You came all this way just to wait for me, are you that afraid I'll abandon you?" Cheng Fei said.

"I just happened to need to talk to the teacher." Shen Xi turned and left.

The teachers' office is indeed next to Cheng Fei's class.

Cheng Fei caught up with her, "You weren't studying hard enough, and the teacher warned you?"

"Paranoia? For the sake of being in the same club, I can accompany you to the psychiatrist this weekend."

"You're the one who needs to see a psychiatrist, Shen Xi, who suffers from severe internet addiction and chuunibyou (middle school syndrome)."

"Does he want to question me but is powerless to refute me, so he attacks me in this way? This may also be accompanied by a personality disorder."

"You're hopeless."

Shen Xi suddenly quickened her pace, as if she wanted to shake off Cheng Fei.

Without saying a word, the two walked one after the other through the long corridor covered with wisteria and entered the club activity building.

In the hallway, a figure with a coat half off leaned against the wall, watching the two approach.

Shen Xi completely ignored Nagasaki Asuna.

The Japanese exchange student then turned her gaze to Cheng Fei. When their eyes met, she tilted her head, blinked, and revealed her signature gentle smile, which was so healing that it made anyone who saw it feel healed.

Who would have thought that someone like her could make such a blatantly manipulative statement? You really can't judge a book by its cover.

As Shen Xi and Cheng Fei passed by, Nagasaki Asuna's eyes flickered, and she smiled as she spoke, "Shen Xi, classmate."

Shen Xi, who was walking in front, didn't even stop for a moment.

"Can I go sit in the research department in the corridor? I'm free in the game department."

"Do as you please." Shen Xi said without turning her head.

Cheng Fei had no idea what Nagasaki Asuna was thinking. They had agreed not to let Shen Xi find out, but now she was taking the initiative to come closer to him.

Nagasaki Asuna walked briskly alongside Cheng Fei, a secret smile playing on her lips.

Then, the girl suddenly and openly took Cheng Fei's arm.

At that moment, there were only three people in the corridor: Shen Xi in front and two others behind.

Cheng Fei was both shocked and furious. He tried to pull his arm out, but instead it sank even deeper.

Shen Xi, who was walking quickly forward, was completely unaware of what was happening.

Cheng Fei glared at Nagasaki Asuna.

Nagasaki Asuna puffed out one cheek at him provocatively.

Cheng Fei did not enjoy it; in fact, he was worried.

Cheng Fei mouthed to Nagasaki Asuna, "What do you want to do?"

The girl first tilted her head in feigned confusion, tapped her chin with her index finger, and then, after Cheng Fei repeated himself, she revealed a mischievous smile and playfully stuck out her little tongue, showing no intention of letting go.

While keeping an eye out for Shen Xi turning around suddenly, Cheng Fei pointed at Nagasaki Asuna's face as a warning.

Unexpectedly, she opened her mouth and was about to bite Cheng Fei's finger.

Cheng Fei quickly withdrew his hand.

What a shameless woman!

Shen Xi's icy voice suddenly rang out, "Cheng Fei..."

15. Notice: Today's club activities will be conducted online.

Cheng Fei felt heavy-hearted, thinking it was all over, but when he turned around, he found that Shen Xi was still walking forward, as if she hadn't looked back at all.

"What is it, Minister?" Cheng Fei used his superb acting skills to make himself sound nonchalant.

Do you have an answer regarding how to measure the speed of light using an electric fan?

Perhaps because she didn't want to see Nagasaki Asuna, Shen Xi didn't turn her head back.

"There's a glimmer of hope..."

"tell me the story."

Nagasaki Asuna gently rested her head on Cheng Fei's shoulder.

Cheng Fei's expression was as if he were carrying a huge boulder.

"Fizeau's experiment used a high-speed rotating gear to measure the speed of light, right? If we modified an electric fan, it might be able to replace the function of a gear..."

Suddenly, a soft, smooth little hand reached into Cheng Fei's hand, their fingers interlocked, the warm touch leaving no gaps.

Cheng Fei shivered.

"And then? Continue," Shen Xi urged.

"Well, using an electric fan instead of gears and finding a laser source, theoretically we could recreate that experiment, but there are a few problems..."

Cheng Fei tried desperately to shake off Nagasaki Asuna, because the stairwell was just ahead, and Shen Xi's direction of travel would turn ninety degrees. If she weren't blind, she could see that the two were holding hands.

"What's the problem?"

"First, the fan speed must be fast enough, at least tens of thousands of RPM, otherwise the optical path will have to be lengthened, and the reflector may have to be placed tens of kilometers away."

Just before Shen Xi stepped onto the stairs, Nagasaki Asuna let go of his hand, pulled away from Cheng Fei, hid her hands behind her back, and struck a harmless pose.

Shen Xi glanced at the two of them sideways. "Anything else?"

Cheng Fei breathed a sigh of relief. "Secondly, the fan speed must be precisely adjustable. The speed must be gradually increased during the experiment until the light path is completely blocked, and then the speed of light can be determined by the fan speed."

Shen Xi climbed a few steps and nodded in approval, "Not bad."

"Yes, yes, it can't compare to your extraordinary brain." Cheng Fei curled his lips. "So why bother researching this? The theory is feasible, but the practicality is practically zero. Just the precise speed adjustment alone is too troublesome. It's not as good as the original gears."

As soon as she finished speaking, Shen Xi suddenly stopped, turned around, and looked down at the two people behind her with a blank expression.

Nagasaki Asuna met her gaze nonchalantly.

"What's wrong?" Cheng Fei asked, feeling a little guilty.

"Today's club activities will be held online. We're dismissed now and going home. So, you, what's your name? Please go back to your game club."

Cheng Fei had reason to suspect that Shen Xi was unhappy that Nagasaki Asuna had gone to the club activity room. "I won't participate in the game. Or we can part ways here. You go play and I'll do my homework."

“No way.” Shen Xi sneered, “You have to come with me to find a high-speed fan with precise speed control.”

"That kind of thing exists, but it's not in the game."

"I heard that there's a limited-edition collectible item from the boss on the fourth floor, which happens to be called the Infinite Electric Fan."

"Game items aside, do you even know what the fourth floor is? It's an unlocked area. Going there is like smuggling yourself in, and the penalty for death is losing all your equipment!"

"So what? Who was it that bragged to me last time that he could walk around the fourth floor like a tyrant?" Shen Xi stared at Cheng Fei. "Or... is my boyfriend just bragging?"
