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

"I understand, The Truman Show." Cheng Fei stroked his chin.

"What do you mean?" Shen Xi frowned at him.

"Classic movies are probably about this kind of thing. What's the second possibility?"

"Twin dimensions," the girl whispered.

"what is that?"

"Do you remember the process by which matter is born from a vacuum?" the girl asked, scrutinizing him.

The boy looked troubled. "Uh, elementary particles are made up of virtual energy, and virtual energy originates from some kind of... spontaneous symmetry breaking in the vacuum? What does that mean?"

Shen Xi said expressionlessly, "Cheng Feiyu still has some memory this time. You can think of it as matter popping out of the vacuum through some mechanism. Under natural conditions, this spontaneous symmetry breaking is pulse-like in spacetime."

What does it mean to be pulse-like in spacetime?

"It means that matter does not suddenly appear at any time and place, but rather a large amount of matter will appear rapidly at a certain time and place, and then quickly subside."

"That's amazing, why?"

"I don't know, I only know that the Protoss have recorded this phenomenon."

Cheng Fei thought for a moment, "Could this be how the Big Bang came about?"

"Perhaps, I'm not sure either," Shen Xi said casually.

"Okay, let's go back to what we were talking about earlier, what exactly is the twin dimension?"

“This is a scientific conjecture of the Protoss. There is no empirical evidence so far, but the theory is highly credible. It assumes that in two dimensions with highly similar tropism values, the laws of physics are also highly similar. If matter emerges in similar spacetimes, then the evolution of matter may also be highly similar, producing similar intelligent life and civilizations. Even the progress of civilization may be almost identical. This is called twin dimensions,” Shen Xi said softly.

Cheng Fei rubbed his chin, looking as if he had just realized something. "I see. Then, Professor Shen, do you think it's possible that Earth has a twin dimension?"

"Of course it's possible, but it's only a possibility."

"Okay." The boy nodded casually.

"Cheng Fei." Shen Xi looked ahead, her tone unchanged.

"what?"

"So you are a reincarnated person from a twin dimension? Did you live in an orphanage when you were little, or on another Earth?" The girl's calm tone made it sound like she was asking a trivial question.

The boy fell silent.

393. Cheng Fei is a little cold.

"Answer me." Shen Xi turned her head to look at him, her face expressionless.

"Teacher Shen, your memory is amazing. You remember even something I just mentioned when I was little." The boy said calmly.

“I have hyperthymesia, so answer my question, Cheng Fei.” The girl said, enunciating each word clearly.

“Okay, yes.” The boy remained silent.

"really."

"Teacher Shen, actually I knew you in my past life. We even got married and had twins. We were very happy, but you passed away not long after. I was reborn here because I want to be with you again." The young man said earnestly.

Shen Xi's eyes flickered, and she remained silent for a second before suddenly stopping, gritting her teeth, and kicking him hard.

"Why, Teacher Shen? Can't you accept being treated as a substitute?" The boy asked in surprise, then lowered his head earnestly. "But I really like you. I will love you wholeheartedly for the rest of my life. Marry me."

"If what you said is true, then you're still fickle after being reborn and meeting me again. You're a complete piece of trash. Why should I be with you?" The girl glared at him fiercely.

Cheng Fei was stunned, then scratched his head, "That's true, I'm sorry I made a mistake earlier, please delete my memory so I can rewrite it."

The girl walked forward with a cold expression. "As expected, Cheng Feiyu is talking nonsense. First of all, even if you really are a reincarnated person from the twin dimension, you couldn't possibly know someone like me, because Star Spirits are intelligent life forms that have broken through the shackles of dimensions and have long surpassed the scope of the twin dimension."

"Teacher Shen, your logic is too tight. I can't even joke with you." Cheng Fei caught up with her and put his arm around her shoulder again.

"I have no interest in such a boring joke," Shen Xi said with a cold snort, nestled in the boy's arms.

"Then we'll go to the hotel now." Cheng Fei took off his coat and draped it over the girl's shoulders.

"Why?" Shen Xi frowned as she looked at her coat.

"Want to go somewhere else? Sure."

I meant clothes.

"Oh, don't you feel a bit cold outside? I'm just concerned about you." The boy said casually.

"Thank you." Shen Xi lowered her head and tightened her coat.

The boy's oversized coat made the slender girl appear even more delicate.

Cheng Fei looked at her delicate, cold profile with a doting expression.

"Stop giving me that disgusting look, and forget about all that nauseating nonsense. This is what you, as a servant, are supposed to do. I'm only doing this because you showed some basic humanity today, otherwise I wouldn't have done it this way." Shen Xi glared at him with disgust.

"Teacher Shen, if it weren't for all those unexpected accidents when we first met last semester, wouldn't you have been inseparable from me by now?"

"Since you know time can't be turned back, stop talking nonsense about what's already happened." The girl turned her face away.

"Okay." The boy suddenly shivered. "It really is a bit cold."

"Even a brute like you has met your match." Shen Xi laughed with a hint of schadenfreude.

"Sigh, we're all just mortals, how could we not feel cold?" The boy hugged her tightly as if trying to warm himself up, and they walked forward.

"Please be gentle, I'm not feeling well."

"I'm sorry," the boy said, putting her at ease.

"You can hug me a little tighter," the girl said casually.

"Ok?"

"If you're really cold."

"Teacher Shen, I'm not used to you being so gentle all of a sudden."

"This is a necessary situation. I've said before that if I could, I wouldn't want to beat and scold you every day. I'm not cold-hearted. I just want to make it clear that your bad impression of me is all your own fault." The girl's tone was unreadable.

"Surely not, don't you have any pride at all? Does that mean I'm hopelessly rotten?"

"Fine, Cheng Fei, let me go." The girl raised her voice.

"I was wrong, Teacher Shen." The boy quickly hugged her.

"He really is trash." The girl gritted her teeth.

"Even trash is your loyal servant, Your Highness."

"Shut up."

The annoyed girl didn't realize that the boy's back had been soaked with sweat some time ago and was now chilly from the wind.

The two walked along the pedestrian street for a while, and Shen Xi asked expressionlessly, "Where exactly is the hotel?"

"It's not far ahead." Cheng Fei checked the location on his phone.

"You've made a reservation?" The girl's gaze swept over the billboards on the exterior walls of the surrounding high-rise buildings.

"of course."

"Show me what kind of hotel it is." Shen Xi frowned and held out her hand.

"Teacher Shen, what's with this sudden interrogation feeling? Here." Cheng Fei handed her his phone.

The girl checked the reservation information, her eyes flickered, and she handed the phone back to the boy.

Cheng Fei observed her face. "Teacher Shen, what are you thinking about?"

"nothing."

"It's obviously there."

"Did you say it?"

"If you don't want to talk about it, that's fine." The boy shrugged as before.

The girl paused for a second, then said, "I thought you would book a couples' hotel, but you didn't."

The boy shook his head and sighed, "Alas, prejudice in people's hearts is a mountain."

"I'm sorry." Shen Xi turned her face away expressionlessly.

"It's alright." The boy's smile was tinged with smugness, and he muttered in a voice just loud enough for the girl to hear, "Looks like sometimes you have to do something unconventional."

Shen Xi's eyes narrowed, and she kicked him hard. "Sure enough, you're always racking your brains to study these things. It's so incredibly boring."

“Teacher Shen, there’s an old saying that actions speak louder than words. No matter what I did, I was just trying to make you happy. You should at least appreciate it.”

"Whether you're trying to amuse me or yourself, you know perfectly well," the girl sneered.

"Oh no, you actually know me pretty well now. Okay, I admit I just wanted to see your cute reaction." The boy smacked his lips.

"Disgusting." The girl glared at him.

"Even if it's really disgusting, it's proof that I like you. Please be secretly happy, my little cutie."

"I don't know how to be happy with this endless verbal harassment." Shen Xi frowned and turned her face away.

The two entered a hotel, and at Cheng Fei's instigation, Shen Xi went to the front desk alone to register for the hotel using her ID card.

After the girl took her room key and entered the elevator, the boy stood guard by the floor buttons, pretending to be a waiter and asking seriously, "Hello, miss, which floor do you want to go to?"

The aloof girl ignored him and pressed the top-floor button herself without expression.

Suddenly, the boy pulled the delicate girl towards him, one hand around her slender waist, the other hand pressing behind her head, embracing her and her long, silky black hair tightly in his arms, his movements impatient and somewhat rough.

Unable to move, Shen Xi felt the intense heat and touch pressed against her, and shivered as if chilled. Her small face, forced to be buried against the boy's chest, furrowed slightly. She kicked him and said in a muffled voice, "Has Cheng Feiyu, who is mentally unstable, completely gone mad?"

The boy didn't speak, but simply kept embracing her, gently stroking her head with a doting expression.

The girl, her face buried in her hands, narrowed her eyes slightly, her gaze flickering. Her tense body gradually relaxed, and her small hands slowly climbed up the boy's back. Her movements were tentative at first, but then became firm. She buried her face even deeper and gritted her teeth, "Trash, don't do this all of a sudden."

"Sorry, I'll let you know in advance next time." The boy tightened his hug.

The girl took a deep breath and remained motionless.

394. Shen Xi will not tolerate betrayal.

The elevator fell silent.

If this scene were seen by others, they would only think that the two were a couple deeply in love, cherishing every moment of tenderness.

The elevator quickly reached the top floor. With a ding, the boy and girl separated in tacit agreement, the boy with his arm around the girl's shoulder and the girl nestled beside the boy, and walked forward in silence.

The hotel corridor was long and quiet, with not a soul in sight; the only sound was the synchronized footsteps of two people.

"Teacher Shen." The boy said casually, one hand in his pocket.

"What?" The girl stared straight ahead, expressionless.

"Shall we continue later?"

"..."

"Teacher Shen?"

"You squeezed too hard just now, it's uncomfortable." The girl's expression remained unchanged.

"Sorry, I'll relax a bit."

"..."

"Teacher Shen?"

"I won't object, but you must abide by the agreement and refrain from any unnecessary actions." The girl raised her chin.

"Okay, that's really cute."

"nausea."
