Qing Cang suddenly asked, how could Wang Zongwei know what he was holding, so he took the spherical object in Qing Cang's hand and observed it carefully, but could not figure out why.
This thing is transparent, which is different from the colored glaze they just pointed out, because there is no trace of impurities in it, and it is not as colorful as colored glaze.
Xu Dezhi said with some embarrassment: "They are our accidental products."
He didn't understand why Qingcang wanted to show this thing to Wang Zongwei.
Unexpectedly, Qingcang said: "This is a glass sphere.
It has a lot to do with the telescope in my hand."
Wang Zongwei exclaimed: "Why is this glass ball related to a magical object like a telescope?
I remember that the word glass was mentioned in the architectural and planning books you gave me, but they were described as being quite large and used as buildings.
The material exists.
This thing is so small and has different properties, and we don’t seem to be producing glass at that level in our city.”
These two things cannot be compared with each other, how can they be related?
Although they are produced in modern times, Wang Zongwei can still recall some of the descriptions about them in the book.
They have the same name but different shapes, which makes his head a little big.
Xu Dezhi also asked: "Commander, what is going on?
The glass and the telescope seem to be different things.
How can they be related?"
Their unexpected product turned out to be related to the magical telescope, and now the two of them were completely confused.
Qingcang said straightly: "It's hard to explain so much to you.
Just remember that this sphere can be used to build a telescope.
As for the principle, I will tell you now."
Now the two of them were excited.
They wanted to get some introduction about the relationship between the two from Qing Cang.
He took out the pen and paper he carried with him and started drawing on the paper.
Draw a concave mirror and a convex mirror respectively.
He said: "Actually, the principle of a telescope is very simple.
It is composed of these two sets of lenses and is surrounded by a cylindrical thing.
The telescope in my hand has the same structure, but it has some more functional things.
This kind of thing is not something we can create.”
A cylindrical thing was drawn on it, respectively, explaining that when the two sets of lenses are put together, they need a supporting object to protect them to achieve the best effect.
Then, he pointed at the eyepiece and objective lens of the telescope, compared the images on the drawings, and began to explain patiently.
He also drew a large number of structural schematics on the drawings.
These drawings only introduced simple principles.
This process lasted for about ten minutes, and finally Wang Zongwei understood it.
Finally, he said: "What I want you to do is to study the relationship between the two and build a high-power telescope.
A telescope that can see farther."
Although he understands the principle, it is still difficult for him to build a telescope.
He does not know how far the objective lens is from the eyepiece, and what angle is required to achieve what magnification.
It is better to leave this kind of matter to Wang Zongwei to study and let them try more to find out the relationship.
In fact, I discovered this glass ball accidentally when I was looking at the glass, so I called Wang Zongwei to come with me and asked him to study the telescope.
This thing has the principle, and it is not difficult.
The difficulty lies in how to make the telescope see clearly. farther.
If it can be successfully researched, it will definitely be no less useful for marching and fighting than siege weapons.
Wang Zongwei asked a key point: "How to produce these concave and convex mirrors?"
"Now, Xu Dezhi, you have to cooperate with Minister Wang and try your best to produce the mirrors he needs.
Xu Dezhi, can you do it?"

"The spherical body held in the commander's hand is just an accidental product, but I believe that we can produce these two kinds of mirrors.
Because they can soften when heated, and their shapes can be changed at will."
Xu Dezhi was sure that they had been dealing with metal all year round, so it shouldn't be a problem to deal with glass.
"There is another question.
Regarding materials, I think there are two materials that can be used to make telescopes.
One is a bamboo tube, and the other is an iron tube.
The telescope in the commander's hand seems to be made of a metal material."
"Yes, this is a material called alloy.
It is light in texture, will not rust, and has many benefits.
But at present, we cannot smelt it successfully.
Let me tell you my opinion.
Although bamboo tubes are available everywhere, they are not durable.
It’s too bad and easy to damage, and although the iron cylinder is not easy to damage, it is too heavy.”
"alloy"
Another professional term made two people feel incredible.
"Yes, it is made by forging several metals or metals by adding other materials.
It can be said to be all in one.
This thing should be introduced in the smelting art."
This explanation will make it clear.
Xu Dezhi looked embarrassed again.
"I seem to have glanced at it, but the book is too thick and it is located at the back.
But maybe I can use a newly discovered lightweight metal.
According to the healing technique, its name is aluminum. ” "Very good.
From today on, this telescope will be completed by the two of you.
Especially Xu Dezhi's work is heavier, and you have to hand over the three people."
In addition to Wu You and Wang Zongwei, Xu Dezhi is also in constant contact with the guys who work in agriculture and creates a large amount of highly transparent glass for them.
Allow them to successfully build the greenhouse and plant vegetables and fruits to complete the mission of Qing Cang.
If successful, the fields would not be idle all year round, and more people would be able to be fed.
Xu Dezhi said: "Commander, please rest assured, as long as there are enough people and good coordination, it will not be difficult."
"If it works, then I wish you success."
"Thank you Commander" Wang Zongwei asked at this time: "Commander, can you keep this telescope for us to study?"
It is not easy to build a telescope out of thin air, but if there are samples for comparison, it will be different.
"Yes, but return them as soon as possible after use.
I want to explain here that these are binoculars, and monoculars are less difficult.
You can start with the monocular first."
Qingcang kept the telescope in his hand.
This thing could only be compared.
It was impossible to dismantle it because there were no tools unless it was destroyed.
If the telescope can be successfully built, the telescope will be invented more than 1,300 years in advance.
You must know that the first telescope was built in 1608.
He has also thought about the use of this telescope.
It can reduce at least 90% of the troops on guard patrols, allowing more troops to be put into battle.
During the march and battle, the Chinese legion can discover the enemy's intentions in advance and prepare in advance.
He will equip each division-level person with one.
Of course, this thing must be easy to carry
