"Thank you for the professor's advice, the kid will remember it in my heart, the professor has something I want to ask you."

Li Yun said.

After listening to Li Yun's question, Tian Ji Baici looked at Li Yun with kind eyebrows and said, "Yun boy, what's wrong, let's talk about it!" ”

Bi Sheng also looked at Li Yun curiously, not knowing what Li Yun was going to ask.

"Professor, you just had a topic of extending the five-dimensional space in class, and I would like to ask specifically, what is the concept of five-dimensional space and what should it look like?"

Li Yun asked.

Tian Jibai looked at Li Yun, and secretly admired Li Yun, but he didn't expect that when he was lecturing, he occasionally extended a small piece of knowledge, and Li Yun was able to take it to heart and let himself figure it out.

Tian Jibai looked at Li Yun, smiled very happily, and said, "First of all, the old man asks you first, we were born in the space of the world, so what is the so-called space?" ”

Li Yun listened to Tian Jibai's rhetorical question, thought for a while, and said: "Space is a set, the basic elements are points, the set of these points is the linear surface, the linear surface body moves towards the x, y, and z axes is three-dimensional space, and the three-dimensional space produces the time axis with the movement, which is the four-dimensional space, so what about the five-dimensional space?" ”

"Yun boy, you even know how the four-dimensional space is created, why don't you know the five-dimensional space? In fact, it is very simple, the five-dimensional space is generated by the movement of the four-dimensional space, theoretically the four-dimensional space can be folded in half, the movement on the basis of the four-dimensional space will produce time stop, the appearance of zero space-time, the space will be miniaturized into points, the appearance of nothingness, and this nothingness continues to move, there will be negative space-time, space-time return, that is, space-time reversal, in the five-dimensional space there will be teleportation, you can see everything in the past. ”

Tian Jibai said to Li Yun based on theory.

Bi Sheng was stupid, as a blue guest, he had also learned a little about such things, but he didn't expect it to be so unbelievable.

"Professor, in other words, if you find the five-dimensional space, can you go back in time and space?"

Li Yun asked.

"Let's just say that, but after all, it's a theoretical thing, and no one has ever succeeded."

Tian Jibai said.

When Tian Jibai said, his eyes were a little evasive, as if he was avoiding Li Yun's eyes.

Li Yun was thinking about Tian Jibai's words, and did not pay attention to this detail.

"By the way, Yun boy, why did you suddenly ask this question."

Tian Jibai continued.

"It's nothing, I just happened to see a book, and then I stopped talking about it in class, and I asked if I was interested, I don't know if it will help the study of Zhizi theory."

Li Yun said with some concealment.

Tian Jibai listened to Li Yundao's information about Zhizi Theory, and said with an earnest attitude: "Yun boy, how is your Zhizi Theory, it's the end of November!" There is still more than a month to go, and the first semester of your junior year is over, and you have no information about your Zhizi theory, are you confident? ”

Li Yun is also thinking about the Zhizi theory, yes!

I don't know whether this kind of thing exists or not, and the formation of theories can only be carried out by various verifications and overthrows, but now I don't have any formed concepts.

"Professor, I know, this is what I'm still thinking about, so what is there to ask the professor in the future?"

Li Yun said modestly.

"The old man's door is open to Yun Boy at any time, that is, you kid must be divided by a set of theoretical basis! This will give you leeway to draft your paper. ”

Tian Jibai said worriedly.

Li Yun looked at Tian Jibai's expectant eyes, and Li Yun knew Tian Jibai's high hopes for him.

"Thank you, Professor, Bi Sheng and I will send you back!"

Li Yun said politely.

Tian Jibai looked at Li Yun with a smile, and then said: "Yun boy, don't forget the true strength of the professor, okay, you and Mushroom should go and do your own thing, if you don't know something, just come and ask the old man." ”

Listening to Tian Jibai's words, Li Yun was stunned, yes!

Professor Tian's strength is far above his own strength.

Li Yun looked at Tian Jibai embarrassedly, and then said a little embarrassed: "Yes! Well, Professor, Mushroom and I will go first. ”

"Let's go! Let's go!"

Tian Jibai took his computer and teaching materials kicked over by Li Yun, waved his hand and said.

After that, Li Yun and Bi Sheng walked towards the outside of the teaching building.

Li Yun and Bi Sheng were going to go to the cafeteria to eat, after all, it was already noon.

Li Yun and Bi Sheng shuttled through the crowded teaching building after class, passing by all the students.

The students are in groups of men and women, talking happily, and some couples are holding hands, and this kind of sweetness may only exist in the campus.

Li Yun and Bi Sheng walked towards the outside of the teaching building and ran to the cafeteria.

"Yun Shao, where is Jingshu? It's all out of class, don't you ask her to eat together? ”

Bi Sheng said.

"Jingshu didn't have a class today, so she went to the company, there may be an important meeting to be held, it should have something to do with the movies her company is shooting recently, we don't have classes in the afternoon, I went to Pangu to report first, I went to Pangu less than once last time, and was caught by some people, saying that I have no one in my eyes, hey, why don't you say we don't have so many things in school?"

Li Yun said.

"Where humans are more advanced than animals is that there are all kinds of intrigues, otherwise how can we improve? In fact, there are also in the school, these are all social vices, no matter where we are, Yun Shao, you won't not find out! ”

Bi Sheng said in a hurry.

Li Yun looked at Bi Sheng a little incredulously and said, "Do you have a big brain!" It's hard to imagine such philosophical words coming out of your mind and speaking with your mouth! ”

"Who doesn't have brain pathways! In fact, in the Internet, this kind of thing is very long, and I have seen it a lot. ”

Bi Sheng said with a little experience.

Li Yunzui looked at Bi Sheng and said, "You said that you are fat and you are still panting, okay, hurry up and eat it, and block your open-minded mouth." ”

When the two of them chattered, they had already arrived at the door of the cafeteria, and at this time, there were many students who were thinking about the cafeteria, lunch, replenishing your energy and preparing for the afternoon class.

Just as Li Yun and Bi Sheng were about to enter the cafeteria, Li Yun's mobile phone suddenly rang, and the caller's avatar was the beautiful face of Huangfu Jingshu.

Seeing that it was Huangfu Jingshu, Li Yun's face was filled with happy joy, and Bi Sheng looked at Li Yun's death with a look of contempt.

But when Li Yun picked up the phone, his face instantly fell.

"You're Li Yun! Wouldn't you be surprised to see this call! By the way, the owner of this phone is drinking tea and chatting with us? I heard that you are a producer and want to talk to you. ”

On the other end of the phone was not Huangfu Jingshu's voice, but a man's voice.

After hearing this, Li Yun's eyes glared angrily, and his gaze was like a torch.

Bi Sheng watched Li Yun's expression change, from the original contempt, to concern in an instant, and quickly took out the computer, without Li Yun explaining, Bi Sheng already knew what to do.

Bi Sheng quickly entered a string of codes in the 'Sky Eye System' in the computer, and the 'Sky Eye System' began to display various pictures, which were also Bi Sheng's ultra-extreme book cattle forks, which also ran freely in the winter.
