In the Song Dynasty, there was no law or order.

At the beginning of the first class, Zhao Jun originally planned to get to know his classmates, talk about their family situations, understand their learning levels, and then conduct targeted teaching.

But now he is blind, even if the old village chief tells him the name, he doesn't recognize that person, so he just lets everyone get to know him first and wait until his eyes are better.

So it is definitely not possible to take ordinary Chinese, math and foreign language courses when he is blind. Zhao Jun remembered that he had considered that the wireless network was unstable and it was easy to disconnect in the mountains, so he downloaded a lot of popular science videos on the Internet.

In addition to the little knowledge of Chinese, math and foreign language, there are explanations about the origin of the universe and the vast universe.

Zhao Jun planned to tell the children about the universe first to stimulate their interest in science and astronomy. What if he could teach a scientist?

When the teacher asked the children what they would do when they grew up, scientist was the most popular option. Zhao Jun always remembered this.

It is a pity that children have become different now. They watch videos with their mobile phones every day. Not only are they little but smart, but some even want to be Internet celebrities when they grow up, which is heartbreaking.

Although the conditions of children in mountainous areas are not as good as those in cities, it stands to reason that they can study nine subjects seriously, get into a good university, and find a good job in society, which is the best way for them to change their destiny.

But now the country also strongly supports the training of scientists and has never treated them unfairly.

If your grades are really good enough to do whatever you want, and you have research in physics, chemistry, biology, and even mathematics and astronomy, and become a scientist, you can basically get a green light all the way, and you can get a lot of scholarships and research funds, which has nothing to do with family poverty.

So Zhao Jun still hopes that he can train a few outstanding students, get into Tsinghua University and Peking University, and devote themselves to scientific research experiments seriously.

Who knows, when they receive scientific research awards in the future, they will mention that the reason why they can become scientists in the future and contribute to the country is that Teacher Zhao did a good job in enlightenment education when they were young.

If this is true, Zhao Jun will laugh when he dreams decades later.

"Ahem."

Thinking about that time is a bit far-fetched.

Zhao Jun coughed twice, then found Yan Shu and asked him: "Uncle Lari, help me check where the mouse is on the computer screen?"

"Mouse?"

Yan Shu came over and asked: "What is a mouse?"

Zhao Jun shook the white wireless mouse in his hand and said: "It's the moving white arrow on the computer desktop."

Yan Shu saw it and said: "It's on the right."

"Then I'll move it to the upper left corner. When I move it to my computer, Uncle Lari will tell me."

"Okay. I've moved it, uh, a little too far."

"Is this right?"

"A little more to the left."

"Is it done?"

"Okay."

"Help me check the location of the D drive."

"I'll help you move it."

Yan Shu saw that it was really hard for him to move the mouse by himself, but he learned it after watching it twice.

Zhao Jun gave him the mouse, and Yan Shu asked while moving the mouse: "Which one is the D drive?"

"There are two drives in it, a solid state drive and a D drive, the second drive."

"Okay."

"Have you found it?"

"Found it."

"Click in, there is a teaching folder in it."

"Teaching. I found it, and then what?"

Yan Shu noticed that there were a lot of things in this so-called D drive, including teaching folders, game folders, data folders, software folders, natural folders, etc., and he had no idea what these things were used for.

"Click in, there is a "Science" folder in it."

"Found it."

"Click in again, find the video called "The Mystery of the Universe", and then double-click the left mouse button."

"Okay."

Yan Shu helped click twice, which he learned from watching Zhao Jun's operation just now. He has been a child prodigy since he was young and learns everything quickly.

"What is the mystery of the universe?"

When the video file was clicked, the sound from the laptop speaker scared Yan Shu so much that his hands trembled.

Zhao Zhen and others were all frightened when they heard the sound. Even though the old women were all from the southwest who were selected by the mansions of various dignitaries and had seen the world, they all opened their mouths and tried hard not to make any sound.

An iron box that can speak by itself?

This really overturned all of their cognition.

Fortunately, Zhao Zhen and Lu Yijian had previously guessed that the mobile phone Zhao Jun was talking about should be able to communicate with people thousands of miles away. With a certain mental preparation, they slowly calmed down, glanced at everyone, and pressed their hands down to signal them not to speak.

However, the old women were fine, but the children couldn't help but scream. Because a certain ratio of men to women was required, Yan Shu brought a son and a daughter. The girl screamed: "It will make a sound."

Yan Shu glared at his granddaughter fiercely. His little granddaughter was usually smart, well-behaved and sensible. Why did she get confused at this juncture?

Fortunately, Zhao Jun did not doubt it. He tapped the keyboard to stop the video from playing, then turned the screen to everyone and introduced it to the children with a smile: "This is a laptop computer. Its functions are a bit like the smartphone in your parents' hands."

When the girl from the Yan family heard Zhao Jun mention his parents, the words "dad" and "mam" were not foreign words, but ancient Chinese. In ancient times, the word for father was pronounced "ba". "Guangya·Shiqin" said: "dad means father", so she understood.

Thinking of her father Yan Juhou who passed away two years ago, the girl burst into tears: "I don't have a father. My father is dead and I don't know what a smartphone is."

"Uh"

When Zhao Jun heard that he had stepped on a landmine accurately, he was embarrassed and didn't know what to say.

Seeing his granddaughter sad, Yan Shu also felt distressed and went up to comfort her: "Yaya, don't cry, Yaya, don't cry, grandpa is here."

Hearing this, Zhao Jun understood why he had not seen anyone else in the old village chief's family except the old village chief and the village secretary in all these days.

It turned out that the old village chief's family was so unfortunate. His son was gone, and his daughter-in-law and wife were unknown. Even if they were, they had to take care of their granddaughter and it was inconvenient for them to come.

It seems that every family has its own problems.

Zhao Jun had no idea how many wives and children Yan Shu, an old man, had, and he sighed for a while.

It took a long time for Yan Shu to comfort the child, and Zhao Jun had to stop introducing the laptop and began to explain the universe to everyone.

"Children, in this class I want to tell you how small we humans are, and it is in this smallness that we have established a civilization and are actively exploring the mysteries of the universe."

"Before playing the video, I want to ask you, do you know how big the land we live on is?"

How big is the land we live on?

The children looked at each other. Although Lü Yijian and the others chose the smartest children in their families, it is estimated that even Zhao Zhen did not know how big the Song Dynasty was, let alone them.

"I don't know."

Everyone answered in unison.

Zhao Jun said: "Our country has a land area of ​​9.74 million square kilometers. It is vast and rich in resources. It has been the Celestial Empire since ancient times and the leader of the East Asian cultural circle. It has been ahead of Western culture for thousands of years in the confrontation with Western culture until modern times."

Uh...

Zhao Zhen and the others looked at each other, so how big is 9.74 million square kilometers?

For them, there is no concept.

"Old village chief, help me unfold the map of our country."

"Okay."

Yan Shu remembered the map in the book "Chinese Geography". He and Zhao Zhen had seen it countless times. Was the area of ​​that map 9.74 million square kilometers?

After a while, the map unfolded, and the huge area of ​​the People's Republic of China slowly appeared in front of the children, which made everyone amazed.

Zhao Jun said to everyone: "Look, this is the map of China. Our country is vast and ranks third among all countries in the world. The population was surpassed by India last year and ranked second. The economy and military are currently only below the United States. It is one of the most powerful countries in the world."

Is this China in the future?

If you just look at the map, it doesn't seem to be anything great.

And a great country is only second in the ranking of countries in the world?

Zhao Zhen thought in his heart.

Now their Song Dynasty is only second to the Liao Dynasty. In other aspects, only the military strength is second, and everything else is better than the other party.

So it seems that the Song Dynasty is not as bad as Zhao Jun said.

Zhao Zhen thought happily in his heart.

"You may not have any idea just by saying this. Uncle Lari and Uncle Nima both like the Song Dynasty. So as a horizontal comparison, let's take the Song Dynasty as an example."

"The Song Dynasty was a relatively poor dynasty in our ancient times. It was not a unified dynasty. The total area was about 2.8 million square kilometers, which was less than one-third of our current one. The population hovered around 100 million, which was less than one-fourteenth of ours."

"In terms of economic development, the Song Dynasty was the best in the world. Western civilization at the same time was still in the Byzantine era, and the overall situation was still quite different from that of the Song Dynasty."

"But it seems that the Song Dynasty performed well at the same time. However, the world around 1000 AD was a worse world. Whether it was the Byzantine Empire, the Arab Empire, the Song Dynasty, or the Liao Dynasty, they were all in a period of decline and basically perished within one or two hundred years."

"Among them, the Song Dynasty is the most regrettable and the most hated dynasty on the Internet, because although it had good economic strength, it did not do well. Instead of using it to develop and become strong, they chose to cede land and pay compensation, and establish their own regime, without any national integrity. "

"Especially, its military strength is very weak. Our country has millions of modern troops, but to destroy the Song Dynasty, it should only need to send a regiment of two or three thousand people with sufficient weapons and ammunition to easily destroy it. "

"Although our country can only rank in the top three in terms of economic strength and military strength, it is probably around the second or third place. But we have our own integrity. Even when we were just founded and poor, we dared to fight against powerful enemies and beat them back beyond the 38th parallel. "

"Nowadays, as our military strength becomes stronger and stronger, and diplomacy becomes tougher and tougher, the enemy's aircraft carriers are getting farther and farther away from our coastline. This is a manifestation of national integrity. "

"Although there are still many kneeling spines in the country, who belittle their own country on the Internet every day, worship foreign things, and think that the moon in foreign countries is rounder. But many people have stood up and firmly believe that their country will get better and better! "

"Why was the Song Dynasty so poor and weak in comparison? This is because the corrupt ruling class and stupid bureaucracy were rampant, the upper class was obsessed with money and wealth, and only knew how to surrender and beg for mercy; internally, they oppressed the lower class people, making them live a life worse than death, and eventually caused the country to perish."

"So we must learn lessons from history, study hard, work hard for the rise of China, and get into a good university in the future. Whether you enter society or continue to do scientific research, you are making contributions to the country. Don't learn from the Song Dynasty, which only knew how to surrender. Chinese people must have Chinese backbone. Do you understand?"

After saying this, Zhao Zhen almost had a heart attack.

The originally happy mood instantly fell to the bottom.

Fuck you.

I will die if I don't humiliate the Song Dynasty, right?
