According to the records of the miscellaneous records of Xijing, Chang'an has a relatively low population and unparalleled skills. It is used as a "seven-wheel fan", and the seven-wheels are all in a continuous diameter. It is said that one fan is blowing out and the room is shivering.

During the Han Dynasty, he was widely praised by the ministers and all installed this item to relieve heat and heat.

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

Later, Ding Yan invented the bedding incense burner.

This incense burner is the first time that humans have made automatic machinery using the principle of gyro movement. It is said that it can automatically rotate and move, which is similar to the gyro invented in modern times.

only……

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

But he was born now and became famous, creating his famous work, Seven-wheel Fan.

But thinking about it makes me feel relieved.

Miscellaneous Notes of Xijing are a collection of jokes written during the Jin Dynasty.

Various unofficial histories and jokes are flying everywhere.

The seriousness of historical materials is far inferior to the historical records and the Book of Han.

Therefore, it is completely understandable that deviations or other problems occur.

In addition, the Han people have customs and skills, and are taught by father and son, master and apprentice. 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 Period and even the Han Dynasty.

The last doctor, Bian Que Chunyu Yi, died during the reign of the late emperor.

Similar existences are also found in other industries.

Now, aren’t there still people who grow melons called ‘Dongling Hou’ outside Chang’an City?

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

After thinking about this, Zhang Yue felt relieved.

But for Ding Yan, he was eager to seek talent. The current situation was not wrong. He wanted to go to the door and visit the cottage three times and ask to get out of the mountain.

So after asking about Ding Yan's residence, Zhang Yue remembered it in his heart.

"Is it Nanlu, Song Street, Chang'an?"

"I will recruit him under my command!"

Such a technological power can play no less than a nuclear bomb!

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

For example, the pedal-type cotton textile machine used by him when he was a child, the earth machine used by great-grandmother and great-grandmother to spin and weave cloth was very simple in structure and very convenient to use.

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

Now, the weaving machines in the Han Dynasty require countless working hours from spinning to making cloth.

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

The standard cloth in the Han Dynasty was eight feet long and two feet wide, and the weight must not be less than twenty Han liang.

The old-fashioned earth loom in Zhang Yue's memory seemed to be able to weave a piece of such cloth in five or six days in the hands of his great-grandmother. This is because the two elders did not put their energy completely on the weaving cloth.

If we could restore the earthen loom in this world...

Isn’t the primary stage of a well-off society just around the corner?

In addition, in later rural areas, there was a threshing foot-stepping machine and a dust-filled wood device called "fan truck".

Relying on Jin Yumu, Zhang Yue could almost trace out the internal and external structures and structures of these devices.

It's just that I can't make it, I can do nothing.

Originally, he wanted to go to the workshop to find someone to realize these things after the Shaofu workshop moved to Xinfeng.

Now it seems that if you can get Ding Yan, there is no need to be such a trouble.

Thinking of this, Zhang Yue was so happy that he even felt a little excited when he walked.

When my sister-in-law saw it, she was also very curious and asked, "Is there a happy event for uncle?"

"Yes!" Zhang Yue walked forward and bowed: "My family is about to have a happy event!"

Whether it is the paper that is about to appear or the Ding Swan that can be almost done with your fingers.

It was a great joy for him and the Zhang family.

When my sister-in-law heard this, she was very happy. She folded her hands together and faced the Zhang family’s ancestral tomb, and murmured: “Bless our ancestors! Bless our ancestors!”

Then he said to Zhang Yue: "Uncle, in August this year, I should offer three animals to honor my ancestors and bless me!"

Zhang Yue nodded and smiled, "Everything depends on my sister-in-law!"

……………………………………

That night, Zhangjia Manor stayed all night long.

More than a dozen workers, under the command and cooperation of Brother Li, mashed the bamboo pulp from several wooden barrels back and forth, again and again until the bamboo pulp is delicate and feels smooth when touched with hands.

Then, according to Zhang Yue's instructions, everyone poured the two plates of kiwi fruit trunks and stems and leaves into each wooden barrel and stirred evenly.

In this way, I was busy until dawn and finally prepared the bamboo pulp into what Zhang Yue wanted to see, which was very soft and almost no different from the dough. If you pinch it with your hands, you can even shape it like mud.

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

Zhang Yue then asked someone to use stone to create a sink about ten steps long, two steps wide, and three feet high in front of the manor's canal.

Draw water from the canal into the canal, then slowly pour the prepared bamboo slurry into the sink, then mix it with the clean water in the canal, and flow into a small pond below the sink.

Zhang Yue got out in person, picked up a stick, and stirred it gently and evenly in the pool, so that the water and bamboo slurry were fully mixed, making it a paste-like liquid.

At the same time, he picked up a bamboo curtain for raising silkworms from his sister-in-law's silkworm room and put it in the pool, while the stirring movement in his hand was still maintained.

In this way, the bamboo fibers slowly fall on the bamboo curtain.

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

The latter immediately took action when he heard this and raised the bamboo curtain from the paste.

Therefore, in the morning sunshine, the first piece of white paper that can be used for writing on the B.C., was shining with an attractive and beautiful luster.

Zhang Yue looked up and was fascinated.

Paper!

The most important carrier of human civilization!

With it, knowledge will not be monopolized by a few people from now on!

With it, family politics will disappear invisibly!

With it, poor people will have a day to make a comeback!

It is the sharp sword of civilization, wherever it passes, and where it looks down upon!

Historically, when paper and printing became popular in continental Europe, the dark medieval era came to an end in the Renaissance movement.

And in its origin.

The civilizations of the Tang and Song dynasties shine brightly on the earth and shine forever.

If there were no Mongyuan, the Qing Dynasty, and the earth in later generations, no two knew who ruled the world.

Looking at it, Zhang Yue took a deep breath and immediately made a decision to write to the emperor to legislate to prohibit the outflow of papermaking technology and related knowledge!

Just like preventing the outflow of tea and silkworm seeds, we must resolutely eliminate any possible ways to spread it.

Historically, ancient China protected tea and silkworm seeds extremely successfully.

If it weren't for the incompetence of the Qing Dynasty, China would have been the dominant industry of the earth in the future!

Of course, this "paper" has not been completely made.

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 the Zhangjia Manor was mobilized.

The bamboo curtains were covered with wet paper, and then they were layered up by people, and then pressed onto them with stones to squeeze out moisture.

By the way, they were carefully separated one by one, hung on wooden poles and bamboo poles, lying upwards and receiving the sun's drying.

The weather is very beautiful. Today is sunny and there are not even a few dark clouds.

So, in the afternoon, white papers that looked as white as jade and looked so beautiful appeared in front of Zhang Yue.

Feeling their smooth and delicate bodies, the entire Zhangjia Manor was filled with a rich atmosphere of festiveness and mystery.

Especially those workers involved in papermaking, their eyes completely changed when they looked at Zhang Yue.

"This is a magical art of gods and ghosts!" Some workers looked at the white paper that was folded up one by one. The papers were delicate and elastic, and they felt like touching silk.

But a day ago, they were just bamboo tubes that emitted foul smell.

But now, they have become a series of smooth and shiny treasures in the sun!

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

"Lord Shenwu!" After seeing his masterpiece of labor, all the workers looked at Zhang Yue, their eyes full of awe and admiration, and they bowed and said, "Lord Shenwu!"

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

When Zhang Yue saw this, he waved his hand and said, "This is not the power of gods and ghosts, but human power!"

But his explanation was obviously not accepted by anyone.

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

Back then, Luan Da was happy and boasted, saying, "The river can be blocked, gold can be made, and immortal medicine can be obtained."

With one or two clumsy tricks, they were swaying, and countless people respected them as gods.

Even today, I believe it and think it is the disciples of the immortals. Although they actually do not show any strangeness, what they call alchemy is just to refine fake gold (there is this kind of fake gold manufacturing technology in later high school textbooks, which is a kind of alloy that looks like gold that is mixed with calamine, red copper and charcoal).

However, this pseudo-gold refining technology has long been ruined.

All the alchemists with a little more famous understanding understand.

But now Zhang Yue has shown a truly magical technology.

Turning useless bamboo tubes into potentially priceless treasure paper.

Paper is not uncommon nowadays.

Even these poor people who have been slaves in the past have come into contact with them.

In the Han Dynasty, due to the development of the silk industry, many silk floes were left in various places. After drying, they became the so-called "Herty", commonly known as paper.

However, people use this paper to wrap some dust.

Of course, some people have made it into the original toilet paper for snot.

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

They are basically unexpected products of the textile industry.

And now, the paper made by Zhang Yue.

But it is a distinct difference from the paper in the past!

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

and……

Everyone knows that the value of this paper will be very expensive!

In the Han Dynasty, all those who could make wealth were highly respected.

For example, the status of women in the Han Dynasty was because they acted as a pillar within the family economy. If women did not raise silkworms and weave cloth, raise chickens and pigs, the self-cultivated farmer class in the world would have long gone bankrupt and disappeared.

And they participated in the manufacturing process of such treasures.

In other words, their fate will be very different from today!

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

This ability to turn decay into magic and turn stones into gold is even more terrifying when worshiping.

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

………………………………

Zhang Yue did not explain more.

Instead, he collected all the dried paper and cut it into sheets about one foot long and five inches wide.

In the end, almost thousands of white papers appeared in front of him.

From them, Zhang Yue selected a hundred of the best-looking ones. He wrapped them in silk, then took these papers, said goodbye to his sister-in-law, and took Rou Niang back to Chang'an.

Going to Chang'an...

Zhang Yue calculated gently and knew it.
Chapter completed!
