I was watching short videos and was seen by ancient people

Chapter 264 Are the people of later generations so ignorant? (two)

Song.

Zhao Zhen frowned while looking at the comments on the marquee. He didn't understand. Don't the people of later generations know that there is a golden house in the book and a beauty like jade in the book?

The Song Dynasty could be so prosperous, but it could not do without these scholars.

Although the entire Song Dynasty became more civilized than military as a result, the current Song Dynasty has already changed after knowing the outcome of the Song Dynasty.

The fate of the people throughout the Song Dynasty was changed because of the knowledge on the sky screen. The people established their own workshops based on the knowledge on the sky screen, and the various products they produced were sold overseas.

It also made the originally prosperous Song Dynasty even more prosperous, and countless people were proud to live in Tokyo City.

But how come in later generations, there are still so many people who don’t know this knowledge, and even think that mirrors come from birth just like people.

What kind of ignorant person is this to make such a comment?

Zhao Zhen hoped that future generations of people would be able to change the world like the scholars he was in the Song Dynasty, but in the end he sighed.

After all, he didn't know how the canopy in the sky appeared, so how could he persuade the people of future generations.

tomorrow.

When Zhu Yuanzhang saw the video on the sky screen, he was also a little surprised that the people of this future generation were so ignorant.

He didn't read any books when he was a child. Only after he became the king of the world did he realize the importance of reading and literacy.

Although he has mastered some knowledge through hard study, he still has many shortcomings compared to those famous teachers and scholars.

He even found it difficult to govern the country. Because of this, he invited many famous teachers and scholars to Prince Zhu Biao, hoping that he could better govern the entire Ming Dynasty.

And Prince Zhu Biao did not disappoint him. He was very clever in helping him deal with various government affairs.

And the knowledge on the sky gradually changed the original Ming Dynasty, and also broadened my knowledge a lot. I knew that the world not only needed Confucian scholars, but also needed different public transportation.

It also allowed Zhu Yuanzhang to see the vastness of the world and know that this big name only occupies a corner of the world, and there is a new continent waiting to be expanded.

Especially when he knew that the Ming Dynasty had a emptied national finance due to the feudal kings, he began to change his national policy since the founding of the country and let those feudal kings grant vassals overseas.

And so much useful knowledge will not be necessary for all people in future generations. How can he not be surprised?

But thinking about the large population in later generations, Zhu Yuanzhang had some understanding. After all, the forest is big and there are all kinds of birds!

Just like Hu Yong, the Prime Minister of the Ming Dynasty, if he were not so arrogant, he would not end up destroying the nine tribes.

"The Freedom of the Wind: First tell me where the glass comes from. In the dynasties where glass existed, it was not cheap. 》

This……

People in various dynasties felt that people did not need to worry so much. Although their technology was not as good as that of later generations, since the emergence of Tianmu, various technologies on Tianmu have been cracked by them.

After the method of making glass was broadcast on the marquee, they had already made it and made a glass mirror for the children.

If people in future generations really travel through time, what they should be more worried about is that their reserves of knowledge are insufficient, or else they will become beggars!

"Looking forward.: Sure enough, everything is interesting as long as there are no exams [tears]. 》

"Youyu: [Crying] I clearly remember doing experiments on the reaction of silver mirrors in high school. I also made mottled mirrors, some of which were made of mirrors and some of which were made of glass. 》

After people from all dynasties saw these two comments, they became even more confused.

Even if they learned this knowledge in school, why would anyone make such unhelpful comments?

At the same time, people in various dynasties are also sighing. The rich people have such abundant learning resources, but they don’t know how to cherish them!

"A drop in the ocean: Most mirrors today are made by vacuum aluminizing. "Look at my seventy-two changes: This technology is no longer used now, it is expensive and the output is low. Nowadays, it is vacuum aluminum plating, which has high production and high quality. 》

"Forever Air Force: [Crying] There was no aluminum in ancient times. Even if it was available, it would be more expensive than gold. 》

What? Is this technology no longer needed in future generations?

After people in various dynasties saw this comment, they began to understand why people in later generations did not know how to make glass mirrors.

After all, who cares about knowledge that is no longer applied?

Only those who have never seen it before would still think of using the knowledge on the sky screen.

At the same time, they were also curious about what kind of metal aluminum was, and it was even more expensive than gold.

Song.

After Zhao Zhen saw the comments on the sky screen, he wanted to know how the aluminum metal was smelted.

Although the Song Dynasty was prosperous, there was always a shortage of various metal coins, and in some places, paper had to be used instead of coins.

If the Song Dynasty could master this technology, I believe it would be able to alleviate the shortage of money.

After emperors of other dynasties saw the comments on the sky screen, they also wanted to own this metal.

After all, if they have more precious metals, they can make more coins and make the entire country more prosperous.

"Holiday Notice: It is better to make convex lenses and concave lenses directly, so that not only reading glasses can be made, but also telescopes can be made. 》

"Please call me a stone: I feel that it is not as good as making convex lenses and concave lenses. It is troublesome to make glass mirrors. Even in ancient times, some materials were lacking and it may not be possible to make them. The ancient technology of convex lenses and concave lenses can definitely be done, and whether it is making reading glasses or Telescopes are valuable. 》

After people of all dynasties saw the comments on the sky screen, they silently remembered the two items, reading glasses and telescopes.

According to the information on the canopy, they knew the functions of two things.

If they dare not make the telescope because it is a military item, then they can do the reading glasses.

I believe that after they make it, many people with old eyes and presbyopia will buy it.

Thinking of this, some people took action, although they didn't know how to make it.

But based on the information on the sky screen, they still experimented again and again.

After the emperors of various dynasties saw the message on the canopy, they quickly ordered the craftsmen to make it.

If reading glasses are made, I believe it will definitely be a good item for the veterans of the court, and it will also greatly improve the efficiency of their work.

If that telescope is made, when a war breaks out, it may be possible to reverse the situation and make them invincible and invincible!

For telescopes, the generals of various dynasties are even more looking forward to it. After all, they have experienced life and death on the battlefield, but they deeply understand the role of information.

And if they have telescopes, they will definitely be able to change a war.
