Li Yun drove in the direction of the Ice Gong University, but turned around halfway and sent Duanmu Rou back to the Pangu Group Building, and Li Yun and Huangfu Jingshu went in the direction of the Ice Gong University.

Li Yun parked the Chevrolet in the underground parking lot of the food city, and Li Yun was very anxious to eat, because he hadn't eaten since he came to class in the morning.

Before I arrived at school in the morning, one thing happened, one thing happened, but fortunately, it has passed now, and there is nothing more down-to-earth than eating.

Li Yun asked for a pot of rice topped with sharp peppers, as well as twenty skewers of roasted meat, seeing Li Yun ordering so much, Huangfu Jingshu was really a little puzzled, and said, "You said that you can't go to a better place?" It's too late to get this kind of messy place, you look at the greasy, it's disgusting. ”

"I think it's good, at least this one can be full, not hungry, or next time when you pay me, I'll invite you!" Li Yun was eating rice bowls while stuffing them into his mouth.

Huangfu Jingshu looked at the miserable situation of Li Yun eating, and couldn't help but smile coquettishly, and then said: "I really don't know if you can swallow those things with your throat and eyes, won't you eat slowly?" Let's starve to death and reincarnate! ”

Li Yun looked at Huangfu Jingshu, although the words were quite unpleasant, but Li Yun could feel Huangfu Jingshu's concern.

Li Yun gradually began to slow down the pace of eating, chewing slowly.

……

Ice Engineering University, Zhang Heng Building, public classroom.

In class, Professor Tian Jibai was giving a lecture to the students with eyes and an infrared pen, although Li Yun experienced some thrilling things in the morning, it did not affect the state and quality of his lectures.

The content of Tian Jibai's lecture was absorbed by Li Yun, and Li Yun instantly felt that this old professor, who once thought that he was a little old-fashioned, had instilled some difficult knowledge into his students so vaguely.

"Communication applications, in our life is closely related, in addition to traditional digital communication, cellular communication, optical fiber communication, computer communication, there should be a kind of communication, he should be faster, the scope is wider, the coverage is more huge, should be far on the basis of traditional communication, you may think as much as possible, in line with the actual way of communication, this will become your future graduation research topic, I don't want a thesis, as long as the result. Who says it first? Tian Jibai said.

After Tian Jibai finished speaking, all the students in the big classroom were talking, Li Yun squinted his eyes, thought about it seriously, and then raised his hand to signal

Tian Jibai saw Li Yun raise his hand, revealing an expected look.

"Li Yun, tell me what you think." Tian Jibai looked at Li Yun expectantly.

Li Yun got up slowly, looked at Tian Jibai, and then looked at the other students, and said: "All our current means of communication rely on satellites, which are equivalent to transit stations, and the time wasted during this period is enough for secondary communication. ”

"According to what you said, we are abandoning satellites for communication, which is absolutely impossible." Another student stood up and disagreed with what Li Yun had said.

Hearing someone questioning, Tian Jibai's face showed a touch of joy, there is competition to make progress.

Li Yun looked at a boy with glasses and a mushroom head, and smiled: "When Bell invented the telephone, it used cables to transmit communication signals, what are we using now?" Wireless signals, that is, electromagnetic waves, do not require a medium, and there is no obstruction in transmission, so that it will be faster and more convenient, which is not necessarily impossible. Before, when I was explaining the supernatural incident of Professor Tian's moat, I said that there is a hypothesis and possibility, which is Zhizi. ”

The mushroom-headed boy pushed his glasses and said, "The Zhizi you mentioned does not exist, it is simply nothing." ”

"When ancient people got smallpox and plague, did they know that it was caused by a virus? I don't think they know, they will think that it is the gods' punishment and condemnation of themselves, and the virus at this time does not exist, and it is the same as the Zhizi talked about now. Li Yun said by analogy.

Listening to Li Yun's reasonable justification of the theories and topics he proposed, Tian Jibai smiled slightly.

"Even if what you say is in line with objective facts, there is a design concept and theoretical basis for the form of Zhizi you are talking about, how to play the function of its application, and what is the source of its power." The mushroom-headed boy said very seriously.

Li Yun looked at the boy, obviously, the standard science man in front of him, Li Yun thought for a while, and then looked at the boy carefully, Li Yun seemed to have the impression that he was no different from himself, and he was also a first-class student, called Bi Sheng.

Li Yun understood the situation, it seems that his Zhizi theory has a little hope that it can be applied to practice, and said: "First of all, Zhizi is not a transmission source of communication equipment, but a tool like electromagnetic waves, which is transported, and the real powerful function of Zhizi is that it is transmitted between communication equipment without passing through satellites, and it is free of time and energy spent on transit, so as to achieve the purpose of saving." But as you said, as for the form in which Zhizi appears, what principle appears, and what kind of power is used, further research is needed, and it is not something that can be decided overnight, but only a conceptual stage. ”

Li Yun briefly said some ideas about Zhizi, but what the further research and development stage looks like, Li Yun still has no idea, after all, this is a question raised by Tian Jibai, as for whether the Zhizi theory can succeed and achieve what he thinks, it still needs to be verified in many aspects.

At this time, Tian Jibai's shrewd eyes did not leave Li Yun's figure for a moment, and at the same time, Bi Sheng's cute figure also appeared in Tian Jibai's field of vision.

Tian Jibai applauded and said: "The two of you have made a wonderful statement, the applied science major has not been so wonderful for a long time, a hundred schools of thought contend, each expressing their own opinions is a manifestation of progress, and the scientific research itself must be bold, so that there can be innovative things to serve the society." ”

Tian Jibai walked leisurely with his hands behind his back, Li Yun and Bi Sheng were looking at Tian Jibai, Tian Jibai said: "The final result of science is to serve the society, that is the meaning of the existence of science, I hope that your final topic can become a product that serves the society." ”

Listening to Tian Jibai's words, Li Yun had an idea that he had never had before, he really wanted to turn that Zhizi theory into reality, it may be that his martial arts have become stronger, and his heart is also strong, and he has never had a desire.

Time flies, and soon the class is over, and Li Yun seems to be still unsatisfied, somewhat immersed in the infinite world of science.

The students left the classroom with a burst of curiosity and confusion, and when Li Yun and Bi Sheng were about to leave, Tian Jibai stopped Li Yun and said, "Yun boy, what you just said is very exciting, I don't know if there is time in the afternoon, the old man wants to ask you to take a look at something." ”

Li Yun looked at Tian Jibai suspiciously, then looked at his mobile phone again, opened a rudimentary app, and a black dot was displayed on the white screen. The location of the black dot is the teaching building of the Art Department of the Ice University of Technology, and Li Yun looked at Tian Jibai with confidence.

"Okay, but I'll make a call first." Li Yun said.

"Okay, it's for Jingshu's girl! Little eyes, you can come along! Tian Jibai said to Li Yun and Bi Sheng with a smile.
