This is a season when the grass grows and the warbler flies, and the campus is full of red willows and green. Here, there were college students my age everywhere, and I walked among them without the slightest hint that I was already a working salaryman. Yes, I'm only 21 years old, and I should have been in class at this age, but I've already graduated. However, if I hadn't gone to college a few years earlier, I'm afraid I wouldn't have met Yuting, right?

Although I was a little nervous, I walked step by step towards the teaching building of the physics department.

I went up to the third floor and walked to the door of the innermost classroom, and I stopped.

In the classroom, the scumbag Shiwen and the associate professor are taking the class very seriously.

I'm used to his style of teaching, because I've listened to his lectures many times, and even I like his interactive way of asking questions. You know, there are few university teachers who dare to accept questions from students, and they prefer to read from the book.

"Teacher." A bespectacled boy about my age stood up and asked, "You just said that time wormholes exist, but why can't we see them?" ”

"If we all saw it, wouldn't we all be able to go back to the past or the future?" Shi Wen smiled.

Make you laugh and I'll make you cry after a while! I cursed viciously in my heart.

"Personally, I believe that the time wormhole exists objectively. Even, the black hole we have discovered is likely to be a time wormhole! ”

Shiwen's words not only surprised the students, but also surprised me.

I've heard a little bit about "black holes". It is said that black holes are something that can devour cosmic stars, but scientists have not been able to draw conclusions on what exactly they are.

Shi Wen continued: "We used to think that time was just a direct path and could only move forward in one direction. However, time is a piece of paper, and no matter how long this paper is, it has its own end. ”

Time is a piece of paper? This is a new idea.

Suddenly, Shi Wen turned his head and looked at me outside the door.

I was startled and quickly turned my head, looking as if I was looking somewhere else, but my ears were still listening.

"But, Professor, if time is a piece of paper, then why do we never go back in time? Isn't that piece of paper free to come and go? The studious student said.

I was also curious, so I turned my head.

Shi Wen had already focused his attention on the classroom again, he smiled and said, "What I said is not what you understand. What I'm saying is that time is a piece of paper, and we are always on one side of the paper, not on the other side, so we never know what the other side of the paper looks like. Unless, you turn the paper over. ”

"Turn it over?" The student frowned.

"It's like this." Shi Wen picked up a blank piece of paper, flipped it over, and pointed to the edge of the paper, "You must get here, cross over from here to reach the other side of the paper." ”

"Is it true that we can go back in time if we just find that edge?"

"No, you'll have to find more paper." Shi Wen smiled, picked up another piece of paper, and then, one in each hand, "Look, these are two pieces of paper, symbolizing different parallel spaces." ”

"Parallel space?"

"Yes, there are a lot of parallel spaces in the universe. In these parallel spaces, there are countless of us. For example, in another parallel space, there may be a me, and a you, who are also taking the same class. It's just that the class over there may have already ended, and it was a few minutes earlier than the time we had here. ”

"Oh, I know that." A fat student sitting below said, "Parallel spaces are independent time systems." ”

"That's right." Shi Wen nodded, and suddenly took out a book from his desk, "This is a book I wrote about the reversal of time and space, and the title of the book is "Time is a Stack of Papers: The Mystery of Time and Space Travel." I'm going to tell you that different parallel spaces exist, like a stack of paper. However, we are only on the front of one piece of paper, but we don't know what is on the back, let alone what we are on the other paper, unless we can find the edge. Or, poke a hole in this piece of paper. ”

As he spoke, he pierced the paper, and a hole appeared in the paper.

"Huh?" The boy standing froze.

"This is the wormhole of time, from here, we can go to another piece of paper without having to go to that edge." Shi Wen smiled, "Besides, the edge of the universe is so big, we will never be able to go to the edge. ”

It must be admitted that Shi Wen's theory of time and space travel is really clever.

In this way, my magic watch is actually a key to enter the wormhole of time, and I entered this parallel space directly from that hole?

I looked down at the watch. The watch was still moving forward, and there was nothing special about it.

"Students, class is about to end, and I know that there is still a lot of things you don't understand. It doesn't matter, if you are interested, you can come to me after class** this book. My book is at a discounted price, but it's only available this month. If you want to **, just come to me and sign up. ”

Wow, it's been a long time, this Shiwen is selling his own book? Come on, this is a sacred university classroom, is it really appropriate for you to openly sell your books like this?

However, I must admit that this Shiwen is really a good material for sales. It's no wonder that Yuting actually fell for this unattractive guy, if I could have such a sharp mouth, Yuting would probably be mine a long time ago, and I don't have any share in this guy.

At this time, the bell rang for the end of class.

"Okay, class." This is the last sentence of Shi Wen.

His students all stepped onto the podium, apparently subscribing to his magnum opus.

However, I wasn't interested in this guy's book, I was only interested in my next head-to-head confrontation with him.

"Professor Shi, please stay." I stopped Shiwen, who had already walked out of the classroom door.

Shi Wen turned his head and looked at me, "Is there anything wrong with you?" ”

I nodded.

"But I don't know you?" Shi Wen frowned, "You are also a student here?" Have you listened to my classes? Well, it seems to be a little familiar. ”

I smiled and said in my heart: Of course you will be familiar, I have listened to your lectures many times, but it is from a distance.

"Professor, can I talk to you about something?"

"What are you talking about?" Shi Wen was stunned for a moment, "I still have something to do, let's talk about it later." ”

"It's about your own personal matter." I deliberately put the word "private" very seriously.

"A private matter?" Shi Wen was stunned again.

"We can talk over there." I pointed to the other end of the hallway, "Or go downstairs and find a place to talk." ”

"Let's get there." Shi Wen seemed a little nervous.

He should be nervous, and even more so if he knew what I was going to say to him next.

I nodded, and we walked to the end of the hallway.

At this point, some students were already going up and down the stairs.

"What are you going to say to me?" When I got there, Shi Wen looked at me suspiciously.

"It's very simple, please break up with Yuting!" I brought it up bluntly.

"What?"

"Please break up with Su Yuting!"

Shi Wen's eyes widened, the eyeballs seemed to be about to pop out, and the green tendons on his head were also exposed.

"Please break up with Su Yuting, break up now!" I repeat again, important things to say three times.

"Who are you? How dare you make such an excessive request to me? Shi Wen was furious, "Do you believe that I will ask the security guards to arrest you now?" ”

"Hmph, you're the one who should be arrested, right?" I didn't panic at all, "Okay, if you don't want to break up, that's fine, then I'll tell Yuting about the ugly thing you did last night, and let her make her own decisions." ”

"Last night?" Shi Wen was stunned for a moment, and suddenly, his face turned red, and then, he turned blue again.

I looked at him as if I was looking at a white rat in a cage, and it was a wonderful feeling.

"What? Dare to do it, don't you dare to admit it? I was not polite, and continued, "Last night, at half past eight last night to be exact, you, the dignified teacher and professor, actually opened a room with a woman in the Lily Hotel, and the room number was 306. ”

"You, what's wrong with you?" Shi Wen's mouth was wide open, and he couldn't say a word for a long time.

I didn't go on, just looked at him.

"Really, really nonsense." Shi Wen suddenly laughed again, "I haven't been there at all, let alone had sex with any woman, do you have any evidence?" ”

Shiwen, what I'm waiting for is your words.

I took out my phone, flipped through the photos, and showed them to Shiwen.

In the photo, he and the woman are hooking shoulders and hugging each other in the hotel lobby. Seeing this photo, Shi Wen was like a frosted eggplant, wilting all of a sudden.

"If you can't see clearly, I still have a video." I laughed, "Of course, I can also send these photos and videos to your school leaders and ask them to help me identify whether this person is you." Oh, of course, if they pretend they don't know you, I'll post it on the Internet and ask netizens to doxing it together. Professor Shi, you will become an Internet celebrity by then. ”

"Don't talk about it." Shi Wen interrupted me, his eyes were full of fear, and he whispered, "You, how much money do you want?" ”

"Money?" I laughed, "I'm sorry, I'm not interested in money." ”

"And what do you want?"

"I just said, please break up with Yuting immediately!"

"You, do you like her?" Shi Wen finally understood, "You want to break us up?" ”

It's you who broke up you, you scum, I couldn't help but scold it, but I still held back.

"Think for yourself, is your girlfriend important, or is your own future important?" Although I admit that I am a bit "mean", there is only one trick I can do against this well-dressed beast.

Shi Wen was like a trapped beast in a cage, he took out a handkerchief from his pocket and wiped his forehead.

I didn't speak, but crossed my hands over my chest, tilted my head, and looked at him with only my lower eyelids.

"Let me think about it." Shi Wen stuffed the handkerchief back and bit his lip.

"That's fine. However, surnamed Shi, you remember to me that unless you kill me, otherwise, as long as you don't leave Yuting, I will make these things public. I said a cruel sentence, "In addition, I have an accomplice, and if something happens to me, he will send these things out for me!" ”

I don't have any accomplices, but if I don't, this guy might really take a risk and kill me!

"Okay, I'll think about it and I'll get back to you in a few days."

"In a few days? No, within today. Besides, you don't know me, how can you answer me? I laughed again, "What, you're going to find out about me and find someone to deal with me?" ”

At this time, Shi Wen was dumbfounded.

"Alright, I'm leaving. Remember, within today, you have to break up with her! ”

"But, but, there's no reason?"

"Find a reason for yourself! Since you can be with another woman, it proves that you don't love her. Since you don't love her, why don't you get out of me sooner! My eyes widened.

Shi Wen didn't dare to look at me and lowered his head.

"Listen, you're going to have to break up with her within today! Otherwise, I'll let you see the newspaper tomorrow! ”

I glared at him viciously, then turned my head and walked down the stairs······
