According to the Xijing miscellaneous records, Chang'an people Ding slow, the skill is unparalleled, it is made 'seven rounds of fan', even the seven rounds are continuous in diameter, it is said that a fan out, the room is full of shivering.

In the Han Dynasty, it was widely praised by the ministers, and they installed it one after another to cool off the heat.

Judging from the description of the Xijing Miscellaneous Records, there is no doubt that this is a primitive mechanical fan powered by human or water power.

Later, this Ding Shun invented the futon incense burner.

This incense burner is the first automatic machine made by human beings using the principle of rotary motion, and it is said that it can automatically rotate and move, which is similar to the gyroscope invented in modern times.

It's just that......

Zhang Yue always thought that this person should be a figure in the middle and late Western Han Dynasty, at least not until after Emperor Xuan.

Who knows that he has been born now, and he is still famous, and he has created his famous work - the seven-wheel fan.

But it's a relief to think about.

Xijing Miscellaneous Records is a collection of paragraphs written during the two Jin Dynasty periods.

All kinds of wild histories and jokes are flying.

The seriousness of its historical materials is far inferior to that of historical records and Han books.

So, it's completely understandable that there are deviations or other problems.

In addition, the Han people have customs, skills, fathers and sons, masters and apprentices teach each other, in order to maintain their reputation, they will basically follow the name of their father or master.

For example, the famous doctor Bian Que was active from the Spring and Autumn Period to the Warring States and even the Han Dynasty.

The last doctor, Bian Que, died in the reign of the first emperor.

There is a similar presence in other industries as well.

Now, isn't there still a melon grower called 'Donglin Hou' outside Chang'an City?

Therefore, it is also very likely that Ding Huan's descendants or disciples will still do things in his name after his death.

Thinking about it like this, Zhang Yue was relieved.

But for Ding Zhuan, he is thirsty for talent, and the current situation is a little wrong, he can't wait to go to the door immediately to visit the thatched house, please get out of the mountain.

So after asking Ding Huan's residence, Zhang Yue kept it in his heart.

"Chang'an Song Street South Lu?"

"I will bring them under my command!"

Such a technical power, in Zhang Yue's hands, can play a role no less than a nuclear bomb!

In Zhang Yue's mind, he remembered countless later generations of machinery that could be realized under the current technical conditions.

For example, the foot-operated cotton loom, the kind of earthen machine that he saw his great-grandmother and great-grandmother spinning and weaving cloth when he was a child, was very simple to construct and easy to use.

Compared with today's textile machinery, its efficiency is ten or a hundred times!

Today, the weaving machines of the Han Dynasty require countless man-hours from spinning to finished fabric.

For ordinary weavers, it takes sixteen days to weave a piece of cloth (nine chapters of arithmetic records), and it takes ninety days for fine cloth!

The standard of cloth in the Han Dynasty was eight feet long and two feet five inches wide, and the weight should not be less than 20 Han taels.

And the old-fashioned earthen loom in Zhang Yue's memory, in the hands of his great-grandmother and great-grandmother, seemed to be able to weave a piece of such cloth in five or six days, which was because the two elders did not fully devote their energy to weaving.

If we could restore that kind of earthen loom in this life......

Isn't the initial stage of a moderately prosperous society just around the corner?

In addition, in the countryside in later generations, there was also a kind of threshing foot-operated machinery and a kind of dust-raising wood tool called 'fan car'.

Zhang Yue leaned on the Jinyu wood, and could almost trace back the internal and external structures and structures of these instruments.

It's just that it won't be made, and it's useless.

Originally, he was thinking that after Shaofu's workshop moved to Xinfeng, he would go to that workshop to find someone to realize these things.

Now it seems that if you can get Ding Slow, you don't have to be so troublesome.

Thinking about this, Zhang Yue was so happy that he even walked with a slight sense of excitement.

When my sister-in-law saw it, she was also very curious, so she asked, "Uncle has a happy event?" ”

"Yes!" When Zhang Yue heard the sound, he stepped forward and bowed: "My family is about to have a happy event!" ”

Whether it's the paper that is about to appear, or the Ding Slow that can almost be reached at your fingertips.

For him and the Zhang family, it is a great joy.

When my sister-in-law heard this, she was very happy, folded her hands, faced the place where the ancestral tomb of the Zhang family was, and murmured: "Ancestor bless!" Ancestors bless! ”

Then he said to Zhang Yue: "Uncle, to worship the ancestors in August this year, you should sacrifice three animals, and thank the ancestors for their blessing and blessing!" ”

Zhang Yue nodded and said with a smile: "Everything depends on my sister-in-law!" ”

……………………………………

That night, Zhang's Manor stayed all night.

Under the command and coordination of the Tian and Li brothers, more than a dozen workers smashed the bamboo pulp in several wooden barrels back and forth, again and again, until the bamboo pulp was delicate and smooth to the touch.

Then, according to Zhang Yue's explanation, everyone poured the two plates of sap that had been prepared a long time ago and squeezed out of the trunk and stems of kiwifruit into each wooden barrel and stirred evenly.

In this way, I was busy until dawn, and finally prepared the bamboo pulp into the shape that Zhang Yue wanted to see - very soft and soft, almost no different from dough, and it can even be shaped like mud when you knead it by hand.

At this point, this bamboo pulp can be used to make paper.

Zhang Yue then asked people to dig out a water tank about ten steps long, two steps wide, and three feet high out of stones in front of the manor's water canal.

Water is drawn from the canal, and the prepared bamboo pulp is slowly poured into the sink, which is then mixed with the water from the canal and flows into a small pool below the sink.

Zhang Yue personally went down, picked up a stick, and gently stirred it evenly in the pool, so that the water and bamboo pulp were fully mixed to make it a paste-like liquid.

At the same time, he picked up a bamboo curtain that he had taken from his sister-in-law's silkworm room and put it into the pool, while the stirring action in his hand was still maintained.

In this way, the bamboo fiber slowly falls onto the bamboo curtain.

Zhang Yue immediately instructed Tian He: "Take out the bamboo curtain immediately!" ”

When the latter heard this, he immediately moved and lifted the bamboo curtain out of the paste.

So, in the morning sun, the first white paper that could be used for writing before the A.D. was shining, revealing an alluring and beautiful luster.

Zhang Yue looked up and was a little fascinated.

Paper!

The most important carrier of human civilization!

With it, knowledge will never be monopolized by a few!

With it, gate politics will disappear invisibly!

With it, the humble scholars have a bright future!

It is the sword of civilization, where it passes, it looks at it!

Historically, when paper and printing became widespread in Europe, the dark Middle Ages came to an end with the Renaissance.

And in the place of its origin.

The civilization of the Tang and Song dynasties shines on the earth and shines through the ages.

If there is no Mengyuan and Manchu Qing, the earth of the future generations, who will rule the world, has not yet known.

Looking at it, Zhang Yue took a deep breath and immediately made a decision - he must be the son of heaven and legislate to prohibit the outflow of papermaking technology and related knowledge!

Just as we do to prevent the outflow of tea and silkworm seeds, we must resolutely put an end to any way that may allow them to spread.

Historically, ancient China was extremely successful in protecting tea and silkworm seeds.

If it weren't for the incompetence of the Manchu Qing Dynasty, the tea and silk industries of the earth in the future generations would probably still be dominated by China!

Of course, this 'paper' has not yet been fully manufactured.

It also requires two processes: pressing and drying.

However, the remaining two processes are so simple that even a fool can do it.

On this day, everyone in Zhangjia Manor was mobilized.

The bamboo curtains are covered with wet paper, which are then stacked on top of each other and pressed against them with stones to squeeze out the water.

By this, they are carefully separated one by one, hung on wooden poles and bamboo poles, and lie flat upwards to be dried by the sun.

The sky is very beautiful, the sun is shining today, and there are not even a few dark clouds.

Therefore, in the afternoon, a piece of white paper as white as jade and looking very beautiful appeared in front of Zhang Yue's eyes.

Stroking their smooth and delicate bodies, the entire Zhangjia Manor was filled with a rich festive and mysterious atmosphere.

Especially the workers involved in the papermaking, the eyes that looked at Zhang Yue completely changed.

"This is the art of gods and ghosts!" Some workers looked at the white paper that was folded one by one, the paper was delicate and elastic, and felt like silk.

Until a day ago, they were just stinking bamboo tubes.

But now, they have become treasures that are as smooth as jade and shine in the sun!

In the eyes of these workers, this is a magic spell that turns decay into magic!

"Lord Shenwu!" After seeing their labor masterpieces, the workers all looked at Zhang Yue, their eyes were full of awe and worship, and they all bowed and said: "Lord Shenwu!" ”

In their understanding, only the legendary immortals and gods can have such the ability to turn stones into gold.

Zhang Yue saw it, but waved his hand and said: "This is not the power of gods and ghosts, but human power!" ”

But his explanation, apparently, was not accepted by anyone.

On the contrary, everyone, including the Tian Li brothers, looked at Zhang Yue like a god.

Back then, Le Chengluan was big, boasting to himself, saying that 'the river can be stopped, gold can be practiced, and immortal medicine can be obtained'.

Relying on one or two clumsy tricks, he swaggered through the market, and countless people respected him like a god.

Even today, they believe that they are disciples of the immortals, although they do not actually show any peculiarity, and their so-called alchemy is nothing more than the refining of fake gold (later high school textbooks have this kind of fake gold manufacturing technology, which is an alloy that looks like gold by mixing calamine, red copper, and charcoal).

However, this kind of pseudo-gold refining technology has long been rotten on the street.

Slightly famous alchemists understand.

But now Zhang Yue has shown a truly miraculous technique.

The useless bamboo tube has been turned into a treasure paper that may be priceless.

Paper is not uncommon these days.

Even these poor people, who used to be slaves, have come into contact with them.

Due to the development of the silk industry in Hanji, there will be a lot of silk wool left in various places, and after drying, it becomes the so-called 'Heti', commonly known as paper.

However, this paper is used as a wrapper to wrap around certain dust.

Of course, some people made the first paper paper to wipe their noses.

Most of these so-called papers are very incomplete, and the performance is very poor and expensive, so no one deliberately makes and collects them.

They are largely an accident of the textile industry.

And now, Zhang Yue makes this kind of paper.

But it is a stark difference from the paper of the past!

In front of this brand new paper, the old paper can be thrown into the trash.

And......

Everyone knows the value of this paper - it will be expensive!

In Hanji, all those who can make wealth are revered.

For example, the status of women in the Han family is because they play the role of pillars in the family economy - if there were no women who raised silkworms and weaving, chickens and pigs, the yeoman peasant class in the world would have gone bankrupt and disappeared.

And they were involved in the manufacturing process of such treasures.

In other words, their fate will be very different from this day forward!

This made them even more grateful and grateful to Zhang Yue.

And this ability to turn decay into magic and turn stones into gold is even more terrifying in addition to worship.

In their eyes, Zhang Yue is no different from ghosts and gods.

………………………………

Zhang Yue didn't explain more.

Instead, he collects all the sun-dried paper and cuts it into sheets about a foot long and five inches wide.

In the end, he was presented with almost a thousand blank sheets of paper.

Selecting a hundred of them in the best condition, Zhang Yue wrapped them in silk, and then took these papers, said goodbye to his sister-in-law, and returned to Chang'an with Rou Niang.

Let's go to Chang'an......

Zhang Yue pinched his fingers lightly and counted, and he already knew.

Now the year is ugly, July is on fire, it is a good time to pretend to be X!
