"One of the best universities in our country, the name is also four words, and it is called the University of Society. From the minute you leave your home to study, you're already in this university. ”

"It's very difficult to graduate from this university, and even if I became a teacher, I still stay in this social university, and I have never been able to get a diploma. Because, to this day, I have not met its demanding graduation standards. Teacher Fan said with a smile, his face was very relaxed, but his eyes were serious.

"What's special is that this social university can't be seen by the naked eye of mortals, but you can feel its magical existence. It's always around you, but you can't see it or touch it. Teacher Fan added.

Yao Yayao didn't understand this unique theory that Mr. Fan said, and only half-understood.

"Can't see or touch?! Why?! Yao Yayao semi-mechanically repeated Teacher Fan's words.

"Ah, that's hard to explain. Mmmm, you've studied physics, about cosmic astronomy, the two basic concepts of dark matter and dark energy, do you know? Teacher Fan unconsciously reached out and wrapped his head around. He wanted to use a more tactful way to tell Yao Yayao what happened last night, but he couldn't say it explicitly, so he could only let Yao Yayao understand it himself.

"I know a little bit about this. The universe we live in, which is said to be visible to the naked eye, accounts for less than 30% of the total mass, and the rest is made up of a large amount of dark matter and dark energy. For example, there seems to be nothing in outer space, but there is actually a large amount of dark matter, but for the time being, no scientific instruments can detect it. Speaking of dark matter, Yao Yayao suddenly became a little interested.

He has always been very fond of astronomy and the study of macroscopic things. However, it is a pity that his current major is completely unrelated to astronomy, which makes him a little regretful.

Teacher Fan sighed and said, "It's good that you understand." ”

"Dark matter and dark energy are currently the biggest mystery in astronomy. However, I dare to assert that in the future, it will be Orientalists from our country who will be able to make explosive breakthroughs in this field. Because, the Tianxia people of our Eastern Continent are born with the ability to obtain a certain mysterious soul connection with dark matter or dark energy. Teacher Fan said again, with a peculiar taste in his tone.

Teacher Fan was saying some strange things again, and Yao Yayao didn't understand again.

According to their own limited understanding, it seems that the great achievements of their own country in cosmic astronomy are not too high. The first moon landing, the theory of relativity, the exploration of Mars, the probe flying out of the solar system, etc., all seem to have nothing directly related to the Tianxia people, the most populous people on Earth. Why did Teacher Fan dare to predict that the Tianxia people would be able to achieve great miracles in the field of dark matter in the future? Yao Yayao was a little ignorant.

Suddenly, Teacher Fan left her seat. Then, from near the TV cabinet in the living room, he took a small frame and held it in his hand.

This frame is actually not small, it is the size of an A4 paper. Inside the frame is a drawing, or rather not a drawing, just a two-panel caricature drawn directly on A4 paper with a black ballpoint pen.

In the middle of the comic, there is an obvious middle line, and the pictures on both sides are also different.

The scene on the left is familiar to Yao Yayao. A near-naked emperor with a crown on his head, accompanied by a group of well-dressed ministers, is on a tour of the streets. On both sides of the road, there were very crowded onlookers. Then there was a little boy in his teenage age age who was clearly inked, with one hand stretched out horizontally, pointing in the direction of the emperor. On his head, a sentence jumped out: "He obviously didn't wear any clothes!" ”

Yao Yayao knows the source of such a picture allusion, which is from the very famous foreign fable "The Emperor's New Clothes".

Naturally, Yao Yayao began to look at the scene on the right side of the painting. The picture on the right seems to be a sequel to the storyline on the left, but the content startles him.

Behind the emperor and his ministers, there were many heavily armed escorts. Many people took out their bows and arrows, bent their bows and arrows, and pointed the arrows in the direction of the little boy who told the truth. All the long arrows did not come out of the string, but it was precisely this that made the whole picture full of a cold murderous aura.

In the position of the little boy, the onlookers next to him had already scattered and fled, leaving him alone, looking very helpless. The little boy reached out with one hand to cover his mouth, looking panicked, as if shocked that his unintentional words would lead to such terrible consequences.

"Teacher, did you draw this?" Yao Yayao said stupidly.

"I painted it. This painting, which has a name, is called "Silence is Golden". Teacher Fan smiled, but it seemed a little reluctant.

After he said this, Yao Yayao realized that in the upper left corner of the painting, there were indeed four headlines of "Silence is Golden".

"There is a semi-monthly internal magazine in the school, called "Xia Gongda Fengyunlu". Next week, there may be some on-campus news releases about that weird cooling device in your dorm room. You may have some personal mood swings after reading it, and the teacher wants you to look at this cartoon. That way, maybe you can calm down. Teacher Fan said with a half-deep groan, and there seemed to be some helplessness in his eyes.

Last night, Teacher Fan was forced to be helpless, and according to the intention of a senior in the school, he went over to induce Yao Yayao and the three of them to sign the supporting materials. Of course, there are some purpose-oriented backroom operations.

However, now he can't make it too clear to Yao Yayao in person. So, I had to give Yao Yayao some psychological hints in advance. Asking Yao Yayao to come over for dinner is just a pretense, the real purpose is to give Yao Yayao this cartoon in person, so that he can prepare himself in advance.

Although Mr. Fan is a genuine teacher in the school, he also can't escape the survival curse of "people are in the rivers and lakes, and they can't help themselves". If you don't do what you mean above, the consequences will be serious, and you will not be able to bear the consequences for a long time.

The real macrocosm is actually a super-large dark box full of dark matter, and the Tianxia people are the best people on the earth at dark box operation! In this way, in the future, who will be the first to comprehend the secret of dark matter or something, except for the Tianxia people, who else can give it to me?! Teacher Fan was laughing at himself in his heart, but he didn't show anything on his expression.

"What's going on?" Yao Yayao said that it was a little inexplicable. Since he came to Mr. Fan's dormitory, Mr. Fan's words seem to be a little inconsistent, as if they mean something, but they are only half of what he said. It's confusing!

Teacher Fan was just about to answer something, but a sudden call from outside interrupted him.

Teacher Fan picked up the mobile phone placed next to him, and looked at the caller ID number, and his expression was a little surprised. He quickly answered the call:

"Xiaobu, it's you! What's the matter? ”

It seemed that the other side of the phone said a few words, and then Mr. Fan casually dropped the phone on the table and walked quickly to the door of the room.

Teacher Fan opened the door of the two floors of the apartment, and walked downstairs without even closing the door. It seemed that things were in a hurry, and he forgot to say hello to Yao Yayao or something. Yao Yayao was a little embarrassed, and he felt inappropriate when he wanted to follow, so he had to stay in the living room inside, and continued to stare at the cartoon stupidly.

The intention of this painting is obvious, that is, to express a suggestive artistic conception of "disaster comes from the mouth".

A few minutes passed, and Teacher Fan came back soon. He didn't come back alone, but walked into the living room with a few people.
