Along the way, Huangfu Jingshu didn't go to make Li Yun choke on words, everything made Li Yun feel very comfortable.

Sent Huangfu Jingshu back to Songbei Villa, under the repeated persuasion of Huangfu Jingshu, Li Yun drove home in a sports car, Li Yun did not dare to drive into the alley where he lived, but found a community parking space a little closer to the alley and listened to it, and the rest of the way, Li Yun stepped on the snow of 'babbling' and returned to the home that once belonged to Li Yun's warmth.

A lot of things happened on this day, and few people were able to happen three memorable and impressive things in one day.

But Li Yun is like this, Li Yun, who closed his eyes, seriously thought about the black ghost who wanted to become a symbol of light in the darkness, so that all this darkness slowly emitted light, and what was the Chehou Wupin mentioned by Qi Wei, how could he be as illiterate as a talker.

Thinking about it, Li Yun gradually fell asleep, listened to the cold wind whistling outside, and gradually fell asleep.

……

Following.

Huangfu Jingshu didn't look for Li Yun, but Li Yun wanted to see Huangfu Jingshu with some expectations in his heart.

Huangfu Jingshu didn't call, and Li Yun started the plan in his heart.

Li Yun went to Bainaohui, bought some electronic materials, and some integrated circuit printed boards, and began to study and make rovers.

After a busy day, Li Yun finally drew a schematic diagram in his house, and pasted some electronic materials on the integrated circuit printed board.

Li Yun has made a slight improvement, because Li Yun's genius in this aspect, coupled with Erlang's ability to have real eyes, makes Li Yun's brain open and almost omnipotent. When I tried again, except for some weak clock signals, everything else was completely normal.

Li Yun was suddenly a little excited, theory combined with practice, it seems that he only needs a little opportunity to start his own business in the future.

One day, Li Yun soaked in the research of that rover, and the best result was that he succeeded, and he was no longer afraid of being by Huangfu Jingshu's side, but worried about what happened to Huangfu Jingshu.

Nothing was said all night.

……

Monday, the first day of the week, the beginning of the week.

Applied Physics in the classroom.

The old professor spoke with relish on the podium, and a group of science men and women with eyes listened carefully.

Li Yun listened carefully, Erlang really looked at what the old professor said, and the power of 'Sheng Shen' was absorbing, Li Yun looked out of the door with some distraction, and then Li Yun suddenly saw a pretty figure flashing by the door of the classroom.

Suddenly, Li Yun seemed to think of something, and then got up and walked outside, because that figure was Huangfu Jingshu.

Li Yun's move immediately aroused the dissatisfaction of the old professor.

The old professor is unusually old-fashioned, and he is completely an old antique that has not been unearthed for a long time.

"You don't do well in class, and you want to leave early, will it affect the efficiency of other students?" The old professor said suddenly.

Hearing the old professor say this, although he felt that the old professor was not wrong, Li Yun also felt that the old professor was delayed, after all, for now, Huangfu Jingshu is important, because it involves a salary of 10,000 yuan a month.

Besides, Li Yun already knows what those old professors said, and he also drew inferences from one another and derived some other knowledge.

"Professor, I already understand what you said, I just want to go to the toilet now, and I didn't tell you that I was afraid of disturbing you and affecting other students. One thing the students have to say, if you really take the lecture seriously, how can you notice my departure? Li Yun asked rhetorically.

Hearing that some students dared to talk back to themselves, maybe it was the teacher's common problem, they were very unhappy, and the old professor said: "Hehe, it's still my fault." Since you said that you understand everything, well, you can answer my questions, and I don't care what you do in my class in the future. ”

"Alright! Professor, please ask! Li Yun looked at the old professor a little strangely.

"Some people say that there are things in this world that modern science can't explain, and that kind of thing we call supernatural events, and in our ice city, the so-called thousands of supernatural events on the moat, how can you explain them with applied physics." The old professor said unscrupulously.

After listening to this, the students below were all surprised, this matter is just an apple and a potato, it doesn't matter at all, and Li Yun smiled silently when he heard it.

"It's actually very simple, paranormal events are unknown to us, and once we know it, we can explain it. There were no mobile phones, no artificial intelligence, no memory chips, and this was also uncharted territory. If it is to be explained by applied physics, then it is Hawking's four-dimensional quantum mechanics. Li Yun deliberately paused and looked at the expressions of the students around him, especially the old professor.

"Stephen Hawking's four-dimensional quantum mechanics is a link between quantum and four-dimensional. Quantum is something in the macrocosm, and if we can look at the world inside the quantum in four dimensions, then the supernatural events will be well explained.

The thousands of troops on the moat are the microscopic particles in the quantum world, and the most likely is a kind of onlooker particle called Zhizi, why is it called Zhizi? My definition is microscopic artificial intelligence full of high-tech.

Mobile phones are macroscopic, and we can operate them, but if we can operate microscopic Zhizi, then it is very likely that thousands of troops are as high-tech as mobile phones, but they are driven by some microscopic Zhizi and appear on the moat. Maybe there are already people in our ice city who have mastered such high technology, but we don't know it. Li Yun talked eloquently, and all the students couldn't help but be dumbfounded, curious how Li Yun could think of such a thing as Zhizi.

Generally speaking, it is a molecule, atom, neutron, proton, elementary particle, etc., and the microscopic wisdom of the microscopic wisdom full of wisdom is simply a fantasy.

The old professor looked at Li Yun, he never left Li Yun's sight for a long time, he has been teaching and educating people for half his life, and there has never been a student who can propose such a bold and insightful thing, the old professor squinted his eyes.

"What's your name?"

"Li Yun." The students in the teacher were suddenly shocked, why is Li Yun so familiar?

"In my class in the future, as long as you think you understand, you can do anything." The old professor actually condescended to Li Yun like this.

"Thank you, teacher, the student is not malicious and insulting to the professor, please forgive the professor, I will abide by the rules in the future." Li Yun said and walked towards the outside of the classroom.

At this time, the students were talking about it.

"He's the champion."

"In the Chinese department, the people in the audience were shocked, and the Pangu Group politely rejected the masters."

"He doesn't seem to be the same as he used to be."

"What a strange guy."

"Can this son be taught?" In the end, the old professor also sighed softly.
