Kong Ming and Pang Tong sat upright, looking at the light curtain with a serious face.

The people in the Chengdu Mansion are basically the same, even if Zhang Fei also took out a pen and planned to do his part.

As a "frustrated person" in the mouth of the light curtain, it can be said that he should know how to farm.

Therefore, I can understand the importance of things such as the water power workshop and the qu plow, and before coming to Yizhou, the re-prosperous public security and Jiangling were also seen by everyone.

Although it is not possible to straighten out the relationship very clearly, but looking at the prosperity of later generations, everyone also understands:

This science is a great thing.

Therefore, everyone present was neither willing nor daring to slack off.

But the first thing everyone felt was surprise and disbelief:

"Is this arithmetic so important?"

King of Science! Mother of Science! The title is simple and straightforward, so it is more straightforward.

If you make an analogy, these arithmetic scriptures are almost equivalent to Confucius and Mencius to Confucianism, right?

Almost instantly, Kong Ming understood the meaning of hatred in the tone of the junior.

Kong Zhongni has been famous through the ages, and his descendants have enjoyed his grace for thousands of years without decay.

What about the sages who wrote the three sutras? is the same as Chen Baoguang's wife, and his name is unknown.

The name of the master craftsman is difficult to see the wild history, and the rice worms of the family are evergreen.

For a while, Kong Ming and Pang Tong glanced at each other, and they were a little embarrassed.

But at the same time, Kong Ming also solved a doubt in his heart:

"No wonder although the light curtain praised the Tang Dynasty before, it rarely mentioned the achievements of the Tang Dynasty in addition to cultural and martial arts."

Pang Tong also understood that this Tang inherited the old system, and the family was already dying, but as a result, the Tang Dynasty became strong and strong, and the gate valve family turned into a scholar gate valve and came back to life.

It's just that if this is the case, the Tang Dynasty relied on martial arts to be strong and prosperous for 300 years, otherwise it would have died a long time ago!

Now that the Tang Emperor learned that arithmetic was expensive, he wouldn't suppress the literature and promote arithmetic, right?

As a result, the poets and poets of the Tang Dynasty became saints, immortals, and kings?

When the magnates visit each other, the "masters" list arithmetic problems one after another, and then those who want to ascend to the sky in one step will bury their heads in rapid calculations, among which the best who are proficient in arithmetic can become "protégés"?

For a while, Pang Tong was amused by his own idea.

However, the later generations seem to have a prosperous literary style, otherwise he Pang Tong wrote a "Legend of the Immortals of the Tang Dynasty" in the name of Erfeng?

When the phoenix grows up, it is the second phoenix, which is very reasonable.

……

Li Shimin doesn't know much about arithmetic, but he still ate a "lemon" accurately, and his mouth was sour:

"After the revival of arithmetic after the Northern and Southern Dynasties, why did the Song Dynasty benefit?"

Li Shimin doesn't need to answer this question, because the light curtain has already made it clear, the family.

"The wealth of the empire is half into its home."

Li Shimin's eyes are red, but he has become the emperor of the Tang Dynasty?

This sentence is too explicit, so that Li Shimin, who has been on the throne for two years, is a little ready to move, and he misses the time when he rode a horse in military uniform.

Wealth is the foundation of the country, so the country is eaten by half of the rice worms of this family, how can this country not fall?

At this moment, the civil and military ministers of the Ganlu Hall reached a simple consensus: this family, which has been severely damaged by the Northern and Southern Dynasties, can no longer sit big!

Du Ruhui thought more clearly:

Instead of being like Na Bo Lingcui, how can he make a name for himself in the prosperous times?

And with the narration of the light curtain, everyone also looked over, and they also wanted to see how powerful the wisdom of the people that broke out in this Song Dynasty was?

[It is said that the Song Dynasty must be inseparable from the four major inventions that influenced the course of civilization all over the world: gunpowder, the compass, papermaking, and printing.

These four basically came before the Song Dynasty:

Gunpowder knows by looking at the name, the medicine that will catch fire, the result of Taoist alchemy, our ancestors even dare to eat this kind of thing, and can only boast that they are not afraid of death.

The Tang Dynasty invented fireworks on the basis of gunpowder, which are still necessary for our festivals.

During the Song-Jin War, gunpowder began to be used in warfare on a large scale, and the world's first artillery was made, and modern warfare began. 】

The first thing that appeared on the picture was a Taoist priest with a fairy wind and bones, only to see him put a few things into the Dan furnace one by one, set up a fire to roast, and then the Dan furnace exploded on the spot without giving face, and the Taoist priest became a fried chicken, and fell down with his head up.

Li Shimin's face darkened a little, and the light curtain said that he seemed to be suspected of taking pills in his later years, but he still remembered, this thing was actually made like this? And it will also blow up?

This group of Fang Shi is really a person who is not sorry to die!

As soon as the picture turned, I saw a group of young people wearing unusually gorgeous Tang costumes, smiling happily at the sky and looking forward to it.

Soon, dozens of tongues of fire were winding up towards the sky.

Just when Zhenguan and the ministers felt that it was nothing more than that, the tongue of fire suddenly exploded, and in an instant the whole sky was as bright as day, and the colorful stars lined up neatly in the sky, forming a magnificent picture.

"This is really a picture of prosperity!" Empress Eldest Sun couldn't help but whisper.

Not only Li Shimin, but all the civil and military forces were shocked for a while: This is what manpower can do? Is this science? Is this the power of the people?

Fang Xuanling was relatively close to the light curtain, and at this time read out the small note next to the scenery of this scene:

"Luoyang Yingtianmen, 2023 Lantern Festival Fireworks Gala"

Li Shimin was in a complicated mood, and after the light curtain was pulled away, he recognized that this was not the gate of heaven that he ordered to burn!

As for why he changed his name, he immediately had the answer in his heart: Wu Zetian! Taboo!

For a while, the emperor's heart was even more mixed, but the light curtain ignored it, and the picture continued to rotate.

This is followed by a quick switch between a rudimentary tin cylinder, a man with only a braid on the back of his head lighting a giant cannon next to him, and a group of blond-haired aliens pulling out a giant cannon that resembles a city wall.

Zhenguan Junchen, who had already seen the fireworks, said that his mood was stable, and then Li Shiyun and Li Jing stood up with heavy breathing.

They saw an iron pillar fly up and barely visible in the sky, then scurry over the plains and mountain lakes, and finally hit a ship at sea, which exploded into pieces and sank into the sea.

The scene turns, and in a house with a curtain of light on the walls, a group of people shout and congratulate each other, and the five-pointed star on the hat shines.

Li Shiyun also read out the annotation next to it:

"Dongfeng Express...... Mission accomplished? ”

At this moment, Li Shiyun had boundless awe for the future generations, a method that had never been heard of even in the legends of gods and ghosts.

What if this Dongfeng Express hits the enemy's general?

The needle drop in the manna hall could be heard, and everyone remembered the Taoist priest in front of them who blew himself up by alchemy, and they felt extremely unreal:

How can this monk's method of seeking death become such a powerful thing?

[Papermaking is the same as printing.]

Cai Lun of the Eastern Han Dynasty improved papermaking, workers in the Tang Dynasty invented rice paper, and the Song Dynasty studied the experience of the previous generations and invented bamboo paper and rice and wheat stalk paper with lower costs and selling prices.

During the Wei and Jin dynasties, Buddhism and Taoism competed, and in order to promote the teachings, it may be that the Taoists at that time invented engraving printing.

Also in the Song Dynasty, after the invention of bamboo paper, printing also developed rapidly, and color overprinting technology was invented, and printing can be basically used in all industries.

Mass-printed Confucian bamboo paper books were unusually cheap, and culture began to spread rapidly, and modern culture set sail. 】

Chengdu Mansion, everyone has been shocked by the gunpowder-derived fireworks and Dongfeng Express.

They had seen the hellish battlefields of the afterlife, but they never thought that the source of everything was gunpowder from the alchemists.

At this time, looking at the scenery in the light curtain, Zhang Fei stretched out his finger and poked Kong Ming:

"Advisor, look, papermaking."

Kong Ming was silent, watching the workers in the workshop go through various processes to make pieces of paper that are white and snowy.

Then the picture turned, and it was a Taoist priest again, pouting his ass and laboriously carving something on a piece of wood.

I saw him cheer, dip one side of the wooden board in ink, and gently press it on the paper, and a paper full of fonts appeared.

On the light curtain, the Taoist priest laboriously carved a piece of wood, and finally pressed and printed them one by one, and the cut paper was bound, only to see that the title page was "Xuandanlu".

Kong Ming pointed to the light curtain and said to Liu Bei with confidence:

"My lord, we are not far from becoming here!"

Printing is something that has been studied for a long time, and the public security has already had special craftsmen for embossing and intaglio engraving, and more inexpensive bamboo paper has also begun to be trialed.

Last month, Kong Ming also sent a letter to his wife, asking her to send a team of papermakers to open a paper mill in Chengdu to study bamboo paper, after all, there are indeed a lot of bamboo in Chengdu.

Therefore, Kong Ming had a little confidence in papermaking and printing, but soon the content in the light curtain shocked him.

As soon as the picture turned in the light curtain, a huge building appeared, and the name of the place was displayed in several large characters next to the door:

National Library of China.

The picture flew up again and drilled in from the entrance, and then everyone in the Chengdu Mansion came out with "oh~".

What do they see? As far as the eye can see, overhead and underground, there are all books.

The light curtain roamed between the shelves, so fast that they couldn't tell the name of each book at all, only a rough classification.

"Ancient Chinese History... Modern Chinese History. ”

"Classical Chinese Literature... Han Fu, Tang poems, Song Ci, Yuan songs. ”

"General Treatise on Philosophy, Religion, and Social Sciences."

In the end, the light curtain ended, so that the people of Chengdu Mansion could understand the collection:

The collection of literature is 37,686,200 volumes!

Too much! The glimpse of the glimpse, but it made everyone in the Chengdu Mansion almost crazy.

The knowledge of the Hereafter is so close to them, yet untouchable!

"Ahhhh Give me a long-distance view and don't let me see even one copy! ”

"If you can make the most of its collection of books, why worry about the Han industry? Why worry about not being able to govern the country and level the world? ”

"I can't become a ghost of China in the future, live in it and read books, and stay in it to read literature."

After all, the Eastern Han Dynasty had a style of learning, and the thirst for knowledge was extremely strong.

And when they saw the library in the light curtain, there was only one thought in their minds:

There is no greater treasure than this.

[And the compass led to the development of navigation in the Song Dynasty, and it is a lie to say too much about this.

Please look, Nanhai No. 1. 】

Today is a disaster...... Poured blood mold
