Chapter 288 I Have Clairvoyance

"There are more than 20,000. Read М"

Hearing this number, Zhao Xu was satisfied.

It seems that the Arms Department can deliver 30,000 flintlock rifles as scheduled.

"What about the artillery?" Zhao Xu asked again.

While manufacturing flintlock rifles, the manufacture of artillery did not stop.

"During this period, the Arms Department mainly delivered field artillery. Now the whole army has 180 field artillery." Chang Wei grinned.

He was very satisfied with this number.

Even for a big war, so many artillery are enough.

Zhao Xu nodded.

According to his plan, the number of field artillery in the whole army should reach 360.

Although he can manufacture artillery in large quantities, the army does not need to manufacture too many.

This thing is a big silver consumer. It can be said that a cannon is worth a lot of gold.

Moreover, artillery focuses on quality, not quantity.

Ten thousand fire guns are also garbage in front of a hundred artillery.

In the Battle of Sarhu during the Ming Dynasty, it was said that there were more than a thousand artillery pieces, but in fact most of them were small artillery pieces like fire guns, and they did not have an advantage in front of the red artillery of the Qing army at that time.

The red artillery of the Qing army was imitated from the Dutch naval guns at that time.

Therefore, unless the enemy has artillery of the same level as his, it is necessary to compete in quantity.

Otherwise, just keep the number of artillery pieces within an appropriate range.

If it is really needed, let the Arms and Arms Department explode the production capacity.

Besides, this is just the field artillery in the army.

If the city defense artillery is included, the artillery scale of the Wangfu’s personal army is already very impressive and absolutely sufficient.

After all, the city defense artillery mounted on the artillery carriage is a heavy artillery.

With a plan in mind, Zhao Xu said at this time: "In addition to these two firearms in this battle, this king has another sharp weapon to give you."

Chang Wei was delighted and rubbed his hands to ask what it was.

Zhao Xu interrupted him directly, "Just like before, keep it secret first, you will know in two days."

"Your Highness, you are going to make me sleep badly at night again." Chang Wei said with a bitter face.

Zhao Xu chuckled twice, thinking that the war was getting closer and closer, he said: "You should arrange the war against Jinzhou first, there is not much time."

Chang Wei's expression suddenly became serious when he heard this.

This is a serious matter, so you can't laugh and joke.

"Yes, Your Highness." He replied yes.

Zhao Xu left Bei Daying directly, and did not go to the palace, but went to Beifang District.

Not long after the Arms and Arms Department moved to Nanfang District, the workshop of the palace moved to Bei Daying.

In addition, the manufacture of cement and glass was separated from the Arms and Arms Department and moved to Beifang District.

This time he was going to the glass workshop.

"Your Highness."

Zhao Xu came over, and the head of the glass workshop immediately came to greet him.

At present, all the workshops in Beifang District are the property of the palace.

Therefore, each workshop has a responsible person.

These persons are under the jurisdiction of the merchant company.

Although the persons are not officials, they are equivalent to clerks, and they receive the silver allocated by the palace.

"No need to be polite." Zhao Xu raised his hand and went straight into the glass workshop.

At this time, the craftsmen in the glass workshop were still working hard.

The red glass liquid was rolling in the furnace.

The craftsmen kept using blowpipes to pick out the glass liquid from it and blow it directly, or put it into the mold to blow it.

When he came to the craftsman, the craftsman had just taken out a piece of glass liquid from the furnace.

The craftsman who was working with him immediately brought a mold with a round hole.

He could see some lines from the round hole.

After the red glass liquid was put into the mold, the craftsman began to blow it.

After the blowing was completed, a standard glass bottle was completed.

If there was something non-standard, the craftsman would take it to the furnace to burn it and then fix it.

At present, the wine bottles and perfume bottles used by the merchant company are all blown with molds.

And these things are all in the book he gave to the glass shop.

Picking up a cooled glass bottle, Zhao Xu nodded with satisfaction.

Then he said to the owner of the glass shop: "The goods of the glass shop cannot stop at these, and need to be diversified. In addition to simple glass cups and glass bottles, more exquisite glassware, such as porcelain-like exhibits, etc."

The owner of the glass shop nodded and said yes.

Thinking of the main business of this trip, he said: "This king has an important matter for you."

After that, he asked for paper and pen and started drawing on it.

The owner of the glass shop looked carefully and found that the thing drawn by King Yan was a round thing.

However, this round thing has two curved surfaces and is as thick as a little finger.

On this round thing, King Yan also marked the size.

"This thing is called a convex lens. I have marked the size for you. You can ask the craftsman to make it with glass." Zhao Xu said.

Now, whether it is the South Square District or the North Square District, they all use the measurement weights and measures he gave.

So the owner naturally understands his marked size.

At the same time, the glass shop also has precise rulers and even vernier calipers.

It is not a problem to manufacture according to the size he gave.

"Convex lens." The person in charge scratched his head.

The King of Yan has many strange ideas, which is something that all the officials in the four counties know.

So although he doesn't understand this thing.

But he knows that it must be a very powerful thing.

So he said: "Yes, Your Highness, I will ask someone to make it."

Zhao Xu nodded, briefly explained some key points of manufacturing, and went back with Xu Lie.

This time, what he wanted to give Chang Wei was not something else, but a telescope.

After having the ability to make glass, it became possible to make telescopes.

He had a ready-made template for making telescope convex lenses in his mind, and he just needed to give it to the craftsmen.

After all, with the size, this was not a complicated problem.

In ancient times, there were jade craftsmen who could polish jade into jade beads.

Even if the craftsmen in the glass workshop made it a little rough, they could ask the jade craftsmen to polish it to a higher standard.

After all, the tools that can grind jade can also grind glass.

In modern times, sandpaper can be used to grind glass.

In ancient times, the tool for grinding jade was called a tuo.

This is a disc-like tool made of natural abrasives, such as sandstone.

Two days later, the person in charge of the glass workshop sent two convex lenses, one large and one small, to the palace.

Zhao Xu looked at it carefully and found that it was indeed a bit non-standard.

So he sent someone to Nanfang District.

Among the craftsmen who polished flintlock parts in Nanfang District, the old jade craftsman was the one who bought two tuo tools from the jade craftsman in Yancheng.

After two days of polishing, the two convex lenses were in Zhao Xu's hands, showing a perfect arc.

This was the convex lens he wanted.

Then, he asked the carpenter to make a cylinder with mahogany, and then cut it in half from the middle.

Carve a groove at the distance he required.

Finally, he put the two convex lenses into the groove, and the wood pieces were put together to become a cylinder again, and then tightened with an iron hoop.

A perfect telescope was born.

With this, they will be able to predict the enemy's moves in the next battle.

Holding the telescope, Zhao Xu returned to the palace.

Feng'er and Luan'er immediately found it and competed to play with it.

Zhao Xu smiled and gave it to them.

Following Zhao Xu's guidance, Feng'er picked up the telescope and looked into the distance, and was immediately stunned.
