"Your Highness, this is not used to cut the barrel, right?"

Military War Office.

Wang Ying looked at the things on the drawings and showed a look of confusion.

In addition to being busy in the Military Affairs Office during this period, he tried his best to squeeze out time to listen to the lectures in the Science and Technology Academy and mastered a lot of novel things.

So he no longer had a look of the drawings given by the King of Yan.

Instead, you can judge one or two based on what you have learned.

"Make it right."

Zhao Xu smiled, and shortly after Ma Han left, he came over with the drawings.

Now that the news of Beidi's development of artillery has been confirmed.

He had to be alert and maintain his dominant position in artillery.

Otherwise, it would be based on how his northern four counties fought against a Northern Di Empire.

Therefore, it is urgent to increase the range and power of the cannon.

So he thought of the hydraulic boring machine.

This is a lathe that cuts the cannon chamber.

In the eighteenth century, Watt used a hydraulic boring machine to cut the inner wall of the steam cylinder.

Of course, the boring machine was used to drill the inner wall of the cannon before.

Due to the technology of casting cannons, the inner walls of cast cannons are generally a bit uneven.

In this way, the shell will encounter resistance when it flies out, causing the shell's range to be shorter and its power to be weakened.

If the inner chamber of the cannon becomes smooth, you have to use a boring machine.

Furthermore, if the hydraulic boring machine is built this time, in addition to cutting the inner wall of the artillery, it will also lay the foundation for the four counties to manufacture steam engines.

Maybe it won't take long to try the steam engine.

At that time, the four counties will officially move from handicrafts to industry.

Such a future is beautiful, but technology must always be carried out step by step from scratch.

Now, I will get the boring machine first, if the drilling chamber is successfully cut.

There will be no big problems with the cylinders that make steam engines in the future.

"I can only say that this is too similar to a hydraulic transfer bed, but the knife looks a little different." Wang Ying stroked his chin.

Zhao Xu nodded, the head of the barrel drilling was pointed.

Because the steel in the barrel is solid, hard drilling is required.

However, what the artillery needs is to scrape the inner wall of the cannon chamber, so the shape of the knife is an inverted L shape.

The length of the short edge of L depends on the size of the cannon chamber.

In his opinion, the tool structure is also not very complicated.

"Can it be made?" Zhao Xu asked Wang Ying.

If Wang Ying said he could not, he would participate in it himself.

Wang Ying showed that you looked down upon me too much and said, "Your Highness, the picture is clearly drawn on it. Now that you have created so many things, the lower officials should have made some progress. I will leave this to the lower officials and report it to your highness in three days."

Zhao Xu smiled and nodded, "Okay, since that's the case, I will wait for your good news."

He naturally hoped that Wang Ying and the officials of the Bing Zheng Office could make progress, rather than asking him to end up in person, big and small things like a giant baby.

Thinking of something, he continued, "By the way, are there enough people to build foreign artillery now?"

At present, the Liang family, Han family, Xie family, and Ma family have all given orders, and the Xiao family and Dou family will definitely come here too.

Now the territory of the two families has become a frontier. Without artillery, they are afraid that they will not be at ease when they sleep.

"It's indeed a bit tight. If the number required continues to grow, I'm afraid the delivery date will be delayed." Wang Ying had a headache. "The most important thing is that these tasks will affect the supply of the Military Affairs Office to the royal family."

Zhao Xu nodded, "In this way, the weapons and armor of the royal family are still manufactured in the Military Control Bureau, and the firearms exported are specially manufactured in Nanfang District. If you transfer the capable craftsmen in Nanfang District back, I will add another batch of new craftsmen to you."

One million people will arrive in the four counties soon.

Moreover, Wang Yanzhong has never stopped returning from Jinzhou Yunqing and has accumulated a lot of money.

But now that Ma Yuan is about to take office, he can no longer be so blatantly robbed people from Jinzhou.

After all, I still have to give him some face.

"Yes, Your Highness." Wang Ying breathed a light sigh.

In fact, the Military and Battle Office also occupies the area of ​​a Minfang.

However, the buildings inside were too old, so the King of Yan asked to move to Nanfang District.

There are still many free places.

If you build some more houses, you can be completely comparable to Chengdefang.

The separation of firearms sold to the outside and firearms manufactured to the inside is also convenient for him to manage.

After agreeing on this matter, Zhao Xu left after the Military Affairs Office.

Although the war cannot be fought for the time being, all preparations cannot be relaxed.

He wants to take advantage of this free time to layout all aspects of the four counties and let the four counties get on the right track of development.

...

Xiancheng.

Murong Hao stood at the top of the city and looked into the distance, his eyes full of pride.

At this time, Ma Jin followed him with a flattering expression.

After receiving the news of the advance of the Western Liang army, the King of Yan and the Ma family soldiers led by Ma Han retreated to Qin Pass at the same time.

The difficulties in Xiancheng were immediately resolved, and at that time he praised himself for making the right choice.

Now, he survived and lived well.

As the King of Qin in Xiliang, he had the same rights over Qinzhou and Yongzhou as the King of Yan over Yanzhou.

The only thing that is needed is to pay part of the taxes to Xiliang every year.

"Shanyu, this place will be your territory in the future, and I will obey your orders." Ma Jin pointed to the land outside Xiancheng.

After the Xiliang army crossed Xiaoguan and stationed in Qingshui City, the closest to Qinguan, Murong Hao arrived in Xiancheng yesterday.

When he first met this Xiliang Chanyu, he naturally flattered him.

After all, his wealth, life, glory, wealth and honor are all in the hands of this emperor.

"Hahaha..." Murong Hao burst into laughter.

He looked at Ma Jin and patted his shoulder.

Qinzhou and Yongzhou were picked up by Xiliang for free.

And this is all thanks to Ma Jin, how unhappy he is.

"I am very pleased to be able to win a general like the King of Qin who is good at fighting. In the future, I hope that King of Qin can be united with me. When Xiliang recovers his vitality, he will break the Qin Pass and seize the Dasong Kingdom with the Northern Di. At that time, I will give you a larger fief." Murong Hao said.

Ma Jin was happy, "Thank you for your grace."

However, from Murong Hao's tone, he also heard that Xiliang would not attack Qinguan for the time being.

This disappointed him a little.

After all, he wanted all the Ma family and all the states belonged to him.

It seemed as if Ma Jin was thinking, Murong Hao said: "It is said that the soldiers of King Yan moved the artillery to Qin Pass. Qin Pass is easy to defend but difficult to attack, and now it is even more iron-clad. It's a pity, but..."

After a change of topic, he said, "At present, Xiliang and Beidi are integrated. The people of Beidi say that they have developed artillery. I will find a way to get some from Beidi. Then maybe this Qin Pass will not be a problem."

"Is that true?" Ma Jin was shocked, then ecstatic.

He was even more convinced that he had made the right choice this time.

Now that the Northern Di has in addition to the invincible iron cavalry, how could Dasong be able to defeat the Northern Di?
Chapter completed!
