You can search "Datang: I was exposed by Princess Changle" in Baidu to find the latest chapter!
But ever since I met brother Xuan, everything seems to be different!
Now she, she doesn't want to!
She wants to fight for this fate by herself!
Li Lizhi clenched her fists and looked into the distance with a firm expression, her eyes full of hope for the future¡ª¡ª
Time passed quickly.
Half an hour later, all the parameters of Lin Xuan were adjusted properly.
Then he returned to the study.
Directly put into the work of making the telescope.
The principle of the telescope is actually very simple, if you do it, you can definitely do it.
After the crystal stone is polished, the lens and reflector are assembled and debugged. With enough patience, it is enough to repeat countless tests and running-in.
But if you think about it, you know that this thing is very time-consuming.
Not to mention that polishing the crystal into lenses and reflectors requires the effort of water droplets to penetrate stone.
What makes it more difficult is to adjust the appropriate distance for each telescope.
Lin Xuan's requirements are not high, as long as he stands on the highest floor of the attic at the highest point of the Lin Mansion, he can clearly read the words on the plaque of the Lin Mansion.
Preliminary estimate, five kilometers away.
This is definitely a bargain in future generations.
But he knew how helpful it would be to have a telescope on the battlefield.
? You can clearly see the text five miles away, and on the battlefield, the widest angle of view is initially estimated to be able to see the enemy seven miles away.
If the terrain of the battlefield is open, this distance may be a little further.
For the current Tang Dynasty, this is undoubtedly another major technological advancement.
In fact, Lin Xuan has no shortage of binoculars. The binoculars rewarded by the system last time are enough for the white-robed army and five thousand tiger and leopard riders.
But this time, the 100,000 army was divided into six groups, and the terrain that the surprise commando passed through was very complicated. If they were equipped with some binoculars, it would be like a tiger with wings added!
In this battle against the Turkic army, Datang has one more chance of winning!
However, he will not rush to send it to Li Shimin.
It seems that the newspapers of later generations must be invented.
Li Shimin would come to his door by himself through the newspaper.
Second, it can also improve the efficiency of collecting intelligence now.
Once this war breaks out, many intelligence points will lose contact.
But as long as the newspaper is published and distributed throughout the Tang Dynasty, this problem will be solved.
The liaison personnel on the intelligence network can communicate with each other through newspapers every day.
To print and distribute newspapers in large quantities, printing is indispensable.
Movable type printing is actually very easy.
Use clay to make characters, each character is a seal, and harden it with fire to make it pottery.
Prepare enough individual movable type in advance, and you can typeset at any time.
When typesetting, prepare an iron plate first.
A mixture of incense, wax, paper ash, etc. to relax on the iron plate.
There is an iron frame around the iron plate, and the iron frame is filled with the characters to be printed, and it is a page.
Then bake it with fire to melt the mixture and integrate it with the movable type blocks.
? Press a flat plate on the movable type while it is hot to make the characters flat.
can be printed.
With this method, printing two or three copies is not very efficient.
If the number of prints is large, dozens or even thousands of copies, the efficiency will be very high.
In order to improve efficiency, two iron plates are commonly used, one for printing and one for typesetting.
After one piece is printed, the other piece is lined up and made up at any time. This alternate use greatly speeds up the plate-making time and is very efficient.
These clay type made by craftsmen are very strong and strong.
Lin Xuan specially asked Flying Wolf to do the experiment.
Let him take a stone to slap these clay movable type, his hands are swollen, and the movable type is not broken.
Yes, Not Bad!
Lin Xuan was very happy and rewarded this skilled craftsman with a tael of silver.
As for engraving, it is not a problem.
In the current Tang Dynasty, there are a large number of masters who are proficient in carving.
Even, Lin Xuan found a few craftsmen who specialize in engraving seals for the royal family.
Once a master makes a move, he will know if there is one.
With these craftsmen who specialize in engraving seals, the speed soars instantly!
Seeing that the clay movable type was about to be completed, Lin Xuan's printing factory was officially opened in Lantian County.
A lot of workers were also invited, and they were told the specific operation process.
Typesetting movable type, and then mass printing.
It's simple and simple, but the main thing is that it's boring.
Lin Xuan really had a lot of things in his hands. What he wanted was to deal with it before the war between the Tang Dynasty and the Turks.
Therefore, he has to choose the right scholar to help.
But now there are not many other things in Lin's residence, but there are a lot of people of all kinds who come here for fame.
Cui Butler's main job now is to help him pick out suitable talents that the newspaper office urgently needs.
Datang wants the common people to be united as one, and the most important thing is to inform the people of the Tang Dynasty about the many changes in the current Datang.
In this era when communication basically depends on legs, the emergence of newspapers is very important.
As long as he founded one in Datang, there would be newspapers with branches all over the country.
So once a lot of things are reported in the newspapers, most Tang people in the world will know about them.
Although many people are illiterate, there are literate people everywhere, and there are also many storytellers now.
With their word of mouth, it is bound to trigger a trend of reading newspapers. (Remember the site URL: www.hlnovel.com
