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

Shen Xi casually twisted the switch, the RPM display showed 2379, a strong wind blew up, stirring the girl's long, silky silver hair.

"This thing spins even when it's not plugged in. What's your explanation, Professor Shen?" Cheng Fei asked.

"It should be some kind of wireless power supply. It is said that these collectibles will stop working on the fourth floor, obviously because they leave the game system."

Cheng Fei nodded nonchalantly, "You're right, but now that we have the goods, can you let me go?"

"Not yet, you have to continue helping me with my research project." Shen Xi glanced at him and said coldly.

"Why should I? It's so late, the club activities are long over, and I haven't even had dinner yet."

"The club activities are over, so now it's time for you to spend time with me as my lover."

"Even capitalists aren't as good at exploiting you. How about this: you hug me and act all cute, and I'll reluctantly stay with you. Otherwise, we'll part ways here."

"Stop talking nonsense, help me finish my project first, then we'll go to Wanda Plaza next to your house, and I'll treat you to dinner."

"???"

What kind of expression is that?

"You even know where I live?"

"The family information registration is written in detail."

"Does your family own Sakura?"

"Checking a student's file isn't that complicated."

"I knew you had a powerful background. Immediately give me 500,000, or I won't play with you anymore."

"Stop dreaming. If you're hungry, hurry up." Shen Xi glared at Cheng Fei and tossed him the electric fan. "You know how to measure the speed of light now. The two of us can finish it quickly."

Cheng Fei, holding the electric fan, suddenly realized, "So you wanted to measure the speed of light in the game after all that."

"Now I realize how disappointed I am in you."

"You're hopeless. What's the point of doing this kind of thing in a game?"

"Stop talking nonsense. You'll know if it's meaningful once you test it. I've already chosen the location. Let's go to Indigo Sea." The girl turned and left.

……

The Indigo Sea is located in a remote corner of a continent. It is not a sea, but a lake, and its water always appears as a deep indigo color.

Under Shen Xi's instructions, Cheng Fei rowed a small boat alone to the lighthouse on the island in the middle of the lake and placed a reflective lens there.

When Cheng Fei returned to the shore, Shen Xi had already set up the rest of the equipment, namely an infinity fan fixed to the ground and a laser rangefinder with a light path passing through the middle of the fan blades, which also seemed to be some kind of collectible.

"The scenery on the Indigo Sea is really beautiful. Let's go boating together next time," Cheng Fei said.

"Why are we rowing?" Shen Xi asked, engrossed in adjusting the equipment.

"Of course it's a date."

"Not interested."

"With your attitude, our relationship won't last."

"My dating expenses will only be paid until next month."

"That's true. Don't you think it's pathetic? Why don't you take advantage of the moment and renew for another year right now?"

"If you keep talking nonsense, I won't want to continue for another two weeks."

"I was too impatient." Cheng Fei made a gesture of zipping up his mouth.

Shen Xi pointed to the equipment, "Okay, next you control the speed of the fan blades, gradually increase it until the rangefinder shows an empty signal. I will record the data. Repeat five times, and then we will go to point number two and repeat five more times."

Cheng Fei looked around the rudimentary experimental site, skeptical. "You can do this? The original experiment used several reflective mirrors at least."

Shen Xi sighed and rubbed her forehead. "The rangefinder has replaced the original function of the lens. If you don't understand, just do as I say."

"You decide." Cheng Fei stepped forward and began to increase the speed as she requested.

"The laser passes between the fan blades, reaches the lighthouse, and then returns. If the fan blades rotate fast enough, the returning laser will be blocked by the rotating fan blades, and the rangefinder will not receive a signal," Cheng Fei pondered.

"The distance the laser travels is known, the time is calculated using the fan blade rotation speed and the number of fan blades, and theoretically, the speed of light can be obtained by dividing the distance by the time, right?"

"There's no need to go over the calculation process at the second-grade elementary school level." Shen Xi held a notebook, staring intently at the fan and rangefinder displays.

"The theory is correct, but will it really work? Games can't simulate real light, so if the rangefinder determines that the fan blades are not obstructed, then even if the fan blades are spinning and smoking, it's the same. It's just an animation anyway."

"The premise is that all of this is a procedure, but I don't agree with that premise." Shen Xi said expressionlessly. "I've estimated that, based on the distance from here to the lighthouse, the fan would be at around 30,000 RPM to completely block the returning laser. How about we make a bet?"

“Okay, let’s bet on who pays for dinner. No, this dinner was originally yours to pay for. If I lose, we’ll split the bill. If you lose, you have to treat me to another meal next time.” Cheng Fei felt confident of winning.

"It's settled." Shen Xi sneered.

19. You can win countless times, but I only need to win once.

The experiment begins.

As the speed increases, the effect of the wireless fan becomes exaggerated, with wind power comparable to that of a real industrial fan, accompanied by a deafening whistling sound.

Shen Xi had to use one hand to hold her long silver hair back to prevent it from being sucked into the fan blades.

5,000 revolutions...

10,000 revolutions...

20,000 RPM...

As the rotation speed approached the range estimated by Shen Xi, ripples suddenly appeared on the lake ahead.

Cheng Fei, who was behind him, also felt a strong suction force and quickly steadied himself in a horse stance.

When the speed reached 30,000 RPM, the rangefinder still showed no signs of interference, and Cheng Fei felt that his next two meals were in good hands.

Then Cheng Fei saw the rangefinder reading jump slightly, and the words "empty signal" flashed by.

Shen Xi, who also noticed this scene, narrowed her eyes.

Cheng Fei doubted his own eyes and continued to increase the speed, aiming for 35,000 revolutions per minute.

The rangefinder display began to flash "empty signal" repeatedly, as if the laser passing through the blades was being obstructed by some periodic obstruction and could no longer return.

Finally, when the RPM display reached 33773, the rangefinder reading stopped changing completely and stopped displaying the words "no signal".

"Stop!" Shen Xi shouted immediately and quickly recorded the data.

Cheng Fei fell silent.

Shen Xi turned off the electric fan, and after the fan blades slowed down, everything returned to calm.

"Looks like someone's going to invite me to dinner," Shen Xi chuckled.

"Impossible." Cheng Fei rolled up his sleeves and carefully checked the equipment. "That must have been a bug. Let's try it again."

Cheng Fei adjusted the laser rangefinder to ensure it was aligned with the reflector on the lighthouse so he could get a reading, before turning the electric fan back on.

Shen Xi watched coldly from the sidelines.

As the fan spins faster and faster, the fan blades exhibit a persistence of vision phenomenon, making them appear to slow down.

After the rotation speed exceeded 30,000 revolutions per minute, the same situation occurred again. The rangefinder readings gradually flickered, the frequency of which increased, and finally it became a blank signal.

Shen Xi recorded the data with a very good mood.

Cheng Fei repeated the process five times in one go and found that as long as the fan speed entered a certain range, the laser rangefinder would fail, which was exactly in line with the theoretical prediction.

"That's enough. Let's go to point two for testing next." Shen Xi calmly closed her laptop. "Due to the increased distance, the empty signal at point two should appear around 20,000 RPM."

The girl's confident words seemed to foresee the future.

"Yes, Teacher Shen." Cheng Fei cooperated with her in moving the equipment, looking pained.

……

Half an hour later, we returned to reality.

Cheng Fei changed into some casual clothes and headed to Wanda Plaza near his rented apartment.

On the bustling pedestrian street, a cool and aloof girl with long, ink-black hair stood under a streetlamp, slinging a small bag over her shoulder, ignoring all the stares around her and focusing intently on the draft paper in her hand.

Upon seeing Cheng Fei, Shen Xi held up a draft paper in front of him, her face beaming with the smugness of a victor. "The experiment was not very rigorous, but ten sets of data were collected from two locations, and the final calculated speed of light was only less than 10 percent off from 300,000 kilometers per second. Do you want to verify it yourself, Cheng Fei?"

Cheng Fei took the draft paper, glanced at it haphazardly, and said, "You win this time. Dinner's on me."

"I thought you were going to renege on your promise."

"I'm willing to accept the consequences of my bet, so don't look down on me."

"What about the realism of the game world? Do you have any new thoughts?" Shen Xi glanced at him with a satisfied look.

"My opinion? My opinion is that this game is so trivial and made me lose the cost of a meal. It's really despicable." Cheng Fei was in a somber mood. To be honest, he didn't care whether the game was real or fake, since it had no practical significance for him anyway.

"Do you still think this is the result of program design?" Shen Xi's expression turned cold.

"Otherwise what? The experimental equipment is all game props. The developers probably expected that someone would do such a boring thing, so they wrote the script long ago."

"As expected, you short-sighted, poorly understanding, and ignorant so-called realists are just stubborn and unenlightened. One failure is not enough for you to learn from your mistakes."

"I admit I lost the bet, but this experimental result only shows that the game's physics are detailed; it doesn't mean the game is real." Cheng Fei shrugged. "Besides, aren't you tired of making this title longer and longer?"

“This level of textual memory is not a burden on my mind.” Shen Xi sneered. “It’s fine if you think that way. I will do a hundred more of these experiments in the future, a thousand more. I hope you can keep your stubbornness.”

Cheng Fei retorted without backing down, "So what if there are a thousand? I'm not afraid even if you make ten thousand, because you can win countless times, but I only need to win once, and I will definitely win, because man proposes, God disposes. No matter how sophisticated the program is, it's still just a program, and as long as it's written by a human, there will be loopholes."

"Then I will prove it to you perfectly the first time." Shen Xi's pretty face was icy cold.

Cheng Fei laughed nonchalantly, "Sure, we'll see."

"We'll see," Shen Xi sneered.

The handsome young man and woman walked side by side, refusing to speak as if in a huff, both looking resentful and avoiding each other's gaze.

Wherever they went, passersby avoided them, unanimously assuming the two were a quarreling young couple.

After a while, Cheng Fei finally spoke, "What do you want to eat?"

"I heard there's a Michelin three-star kaiseki restaurant nearby..." Shen Xi looked up casually.

Cheng Fei's eyelids twitched. "Leave room for maneuver in your actions, so you can meet again in the future, Shen Xi."

The girl revealed a smug look, "Forget it, I don't want anything too greasy tonight, I'll just find a dim sum restaurant."

Cheng Fei finally breathed a sigh of relief.

This woman has at least a conscience.

Academy City recruits students from all over the world, so naturally, its street food offers flavors from all corners of the globe.

The two found a decent Cantonese dim sum restaurant and sat down. Shen Xi ordered shrimp dumplings and boat congee, while Cheng Fei ordered stir-fried beef noodles and steamed spare ribs.

The stir-fried noodles, infused with the flavor of beef, were fragrant and smoky. The ribs were tender and juicy, fresh and flavorful. The delicious food made Cheng Fei's painful mood a little better.

After a while, the middle-aged boss, who spoke with a Cantonese accent, came over to Cheng Fei and said, "Handsome boy, your girlfriend is very pretty. This steamed chicken feet is a gift for you."

After saying that, he put down the steamer and walked away.

Cheng Fei looked at Shen Xi.

The girl, who was drinking porridge with her eyes lowered, glanced at him, snorted coldly, and said nothing.

Cheng Fei picked up the soft and tender chicken feet and ate them without any qualms.

"Teacher Shen, I have a question for you. You can refuse if you don't want to talk about it," Cheng Fei said, holding a bone between his fingers.

Shen Xi put down her spoon. "Speak."

"What characteristics of men do you think are most attractive to women, generally speaking?"

Why are you asking this?

"It's nothing, I've just been researching the most effective ways to increase one's charm lately."

Shen Xi shook her head. "Every woman has different preferences and standards. A healthy body and a neat appearance are both important, but if I had to choose one specific one, I would say a smile."

"Smile?"

"That's right. A smile is the most universal expression of positive emotions. A well-timed smile can instantly bridge the gap between people. No one can resist a friendly smile, and women are no exception."
