Datang: I was exposed by Princess Changle

And she may also be able to escape the tragic fate of marrying a Turk and getting married!

She doesn't want to marry!

Maybe if she hadn't met Brother Xuan, she might have accepted her fate because of it!

Because from the moment she was born, as the most honorable princess of the Tang Dynasty, she was destined to shoulder the responsibility and honor of the royal family!

Chapter 104 Start a Newspaper Office!

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 tightly and looked into the distance with a firm expression, her eyes full of hope for the future.

Time passed quickly.

Half an hour later, all the parameters of Lin Xuan were adjusted properly.

Then he returned to the study.

Directly into the work of making telescopes.

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 think about it and 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.

The more difficult part is to adjust the appropriate distance for each telescope.

Lin Xuan's requirements were not high, as long as he stood on the highest floor of the attic at the highest point of the Lin Mansion, he could clearly read the words on the plaque of the Lin Mansion.

According to preliminary estimates, five kilometers away.

This is definitely a bargain in later generations.

But he knew how helpful it would be to have a telescope on the battlefield.

You can see the text clearly from five miles away, but on the battlefield, with the widest viewing angle, it is preliminarily estimated that you can 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 army of [-] was divided into six groups, and the terrain the surprise commando passed through was very complicated. If they were equipped with some binoculars, it would be like a tiger with wings added!

Datang's chances of winning this battle against the Turkic army will be one point higher!

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 the 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.

Printing is indispensable for mass publishing and distribution of newspapers.

Movable type printing is actually very easy.

Characters are made of clay, each character is a seal, and it is hardened with fire to make it pottery.

Prepare enough individual movable type in advance, and you can typeset at any time.

Prepare an iron plate when typesetting.

A mixture of incense, wax, paper ash, etc. for relaxing 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 the whole is a version.

Then bake it with fire to melt the mixture and integrate it with the movable type blocks.

Press the movable type with a flat plate while it is hot to make the characters flat.

It can be printed.

Using this method, printing two or three copies is not very efficient.

If there are more prints, 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 the other 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 quite 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.

Lin Xuan even found a few craftsmen who specialize in engraving seals for the royal family.

As soon as a master makes a move, he will know if there is one.
