Chapter 140: Look at my wind-powered papermaking technique
In the Imperial Study Room of Ganlu Hall.
"Your Majesty, although the theory of nationality proposed by His Highness is beneficial to us, the Tang Dynasty."
"But in actual implementation, it would consume too much manpower, material and financial resources, and the gains would outweigh the losses."
"Rather than do this, it is better to shelve this plan for the time being."
Tang Jian pursed his lips and said, "Wouldn't it be better to spend all these financial and material resources on useful things?"
"Having said that."
"But the census is imperative."
Li Shimin and Li Chengqian said exactly the same thing.
This also made Tang Jian very helpless.
"Yes, I also know that the census will bring many benefits to the Tang Dynasty."
"But have you ever thought about it, Your Majesty, that once the census is launched, many old rules will inevitably be broken."
Tang Jian looked confused: "When the time comes, I'm afraid it will cause dissatisfaction from many aristocratic families..."
"What's wrong with being dissatisfied?"
"Do I still need to be restrained by them when I do my work?"
Li Shimin sneered and said: "To tell you the truth, although Gan'er proposed conducting a census, it is something I have wanted to do for a long time."
"These clan members only receive free wages and do not pay taxes. What is the use of keeping them?"
"Rather than letting them get bigger and bigger and ride on me to suck blood, it's better to pull them out as soon as possible."
Don't wait for Tang Jian to speak.
Li Shimin changed the subject and asked: "By the way, it was Gan'er who told you that he would solve the paper issue?"
"Exactly."
"Then he can tell you how to solve it?"
"That's not true."
Tang Jian pondered for a moment and said, "But His Highness seems to have said something about improving papermaking technology."
"Improved papermaking?"
Li Shimin raised his eyebrows, feeling a little curious.
Does Li Chengqian still understand these things?
Where did this little guy learn it from?
Thinking about it, Li Shimin simply waved his hand and said: "You go down first, and you will do whatever Gan'er tells you."
"If there is something big that you can't handle, come back to me."
Hearing this, Tang Jian sighed He took a deep breath and said, "I take my leave."
After Tang Jian left, Li Shimin stood up and called: "Eunuch Zhou."
"The old slave is here."
Eunuch Zhou came out from behind the screen.
"I'm leaving the palace with you. I want to see what this guy can do."
"yes."
…
At the same time, in the palace of Prince Qin.
Li Chengqian asked Cheng Huailiang to buy a large pile of bamboo and wood.
"Your Highness, what is the use of bringing these things back..."
Cheng Huailiang rubbed his shoulders and said, "Is this also related to the nationality theory?"
"Of course."
Li Chengqian pulled out a wooden board from the wood and said: "If my invention can be successful, these things will be enough to change this era."
What he wanted to invent was the wind mill that was very popular in Europe in the twelfth century.
If he can really develop it successfully, the wind will generate kinetic energy, and the kinetic energy will drive the millstone, and the millstone will crush wood and other objects.
Then, the energy can be continuously produced to produce pulp for paper making.
If we could form a papermaking assembly line like later generations, would paper still be expensive?
Moreover, the wind mill can not only do these things, it can even make some simple machines.
Although they are small things, they are enough to change this era.
But Cheng Hualiang obviously didn't understand these.
He looked at Li Chengqian with a puzzled face.
Just using these wooden boards can change this era?
Wait, what does the phrase "changing times" mean?
Seeing his appearance, Li Chengqian knew that he had said too much.
But he didn't bother to explain it to someone with Cheng Hualiang's IQ, so he simply said: "Okay, you won't understand even if I explain it to you."
"Go and call Carpenter Zhang over. I have something to give you."
"good."
Cheng Huailiang responded and went to call someone.
Li Chengqian quickly went to draw the drawings.
The structure of the wind mill is not complicated.
The blades of a windmill have a fixed shape, one side is high and the other is low.
In this way, the wind can be blown in one direction on the surface of the blades, thus changing the direction of the passing wind and generating kinetic energy.
It’s just that the size of the windmill and the connection points of the windmill are more complicated.
This completely depends on Zhang Carpenter's craftsmanship.
Fortunately, Li Chengqian once made a wind propeller, and Zhang Carpenter was familiar with these things.
With his men, he built the windmill that afternoon.
At this time, Li Chengqian hurriedly ordered his men to set up the windmill and connect the transmission shaft and other things.
At this point, a simple version of the windmill is formed.
At this time, everyone gathered under the windmill.
Watching the wind blowing on the windmill, the windmill slowly rotates.
Then it drives the gear, which in turn drives the transmission shaft.
Finally, the transmission shaft drives the grinding plate and slowly rotates.
Li Chengqian hurriedly threw a few wood chips that had been cooked into the millstone.
As the millstone rotates slowly, white pulp flows out along the edge gaps.
When the bucket of paper pulp was filled, Li Chengqian carried the bucket full of pulp to the big bucket that had been prepared without the help of others.
Inside the pool, several curtains made of light gauze have been placed.
After the pulp is mixed evenly, use a spoon to pour the pulp on the curtain.
Later, Li Chengqian took action himself, holding the curtain and shaking it in the water.
"His Majesty……"
Just when Li Chengqian shook the curtain.
Li Shimin suddenly walked in.
Seeing this, the surrounding servants stepped forward to salute.
Li Shimin waved his hand, indicating that everyone should not be polite, let alone disturb Li Chengqian.
Li Chengqian raised his head and glanced at Li Shimin. For the first time, he didn't speak. r> He shook the curtain very seriously.
As he shook, the pulp spread bit by bit and spread everywhere.
Less than half an hour later, Li Chengqian lifted the curtain.
A piece of pure white rice paper has suddenly been formed.
This scene made everyone around him dumbfounded.
Although they have all seen paper, they have never seen how paper is made.
Today, their eyes were opened.
Even Li Chengqian couldn't help but cheer: "It's done!"
He held up the curtain to show off to Li Shimin: "Father, I really did it!"
Tell the truth.
He didn't expect that he could succeed at first.
But now it seems that I am still very talented.
Li Shimin also put away his surprised expression and looked at Li Chengqian with pleased eyes.
"well done."
Although there are only four short words, there is an indescribable pride in it.
How can my son be worse than others?
Others can make paper, why can't my son?
…
Inside the main house.
"Father, if we use this method to make paper, the paper required for nationality theory will no longer be a problem."
Li Chengqian looked at Li Shimin with a smile and said: "Now, can the nationality theory be implemented?"
"sure."
"Have I not always been in favor of your decision?"
Li Shimin chuckled and said: "And in my opinion, this is not the only benefit."
"ah?"
Li Chengqian raised his eyebrows and looked at Li Shimin in confusion.
Li Shimin looked at Li Chengqian and asked, "Do you know why aristocratic families can monopolize talents?"
Li Chengqian frowned, and after a while he asked: "Is it because the aristocratic family has books in their hands?"
"clever."
Li Shimin looked up and smiled: "You really helped dad a lot this time..."
