Chapter 152

The first gun was successfully cast, and the atmosphere in the equipment department was as hot as coal in the blast furnace.

Every craftsman's face is full of smiles.

This month, they worked day and night, people have lost ten jin, in order to complete the task arranged by the king of Qi.

Now we are just waiting for the test firing of the gun. If it is successful, it means that the equipment department has really mastered the production technology of the gun.

"Your Highness, you'd better try. The craftsmen are waiting eagerly." Chen Qi is afraid that Xiao Ming won't let them watch the test firing of the gun. It's just as painful as having a baby and not knowing that Chou Jun has been brought.

"Yes, your highness, let's see." The craftsmen in the equipment department asked one after another, and their eyes were looking forward to the artillery power.

The craftsmen's bodies were covered with sweat and iron powder, and a smell mixed with metal and sweat floated in the equipment department.

With so many requests, Xiao Ming can't refuse. He was just joking with Chen Qi.

Of course, these craftsmen are required to participate in the artillery test. Only in this way can problems be found and rectified in time.

"Well, it must be too late today. We need a suitable site. Moreover, the artillery is very heavy. Transportation is also a problem. At the same time, it's also artillery shells."

When he mentioned the shells, Xiao Ming's tone became heavier.

Artillery shells naturally need to be suitable for the current artillery. If they are too big to be loaded, the efficiency of small gunpowder will be greatly reduced, and it is likely that the shells will hit the feet.

Before the artillery was produced, the equipment department could not accurately calculate the caliber of the artillery, because it did not dare to produce artillery.

Xiao Ming has some helplessness for this. After all, there is no accurate measurement system in this era, and the products produced can not be accurate. At present, only the caliber of the muzzle can be used to produce shells.

Otherwise, the shells produced may not fit in.

He thought that the precision measurement system should also be established, so that the production of artillery and shells would not interfere with each other.

It only needs to produce in strict accordance with the size, and it is also necessary for the future industrial development of Qingzhou.

After all, after the lathe can participate in the production, we need a measurement standard to mass produce parts.

Although Chen Qi and others are in a hurry, if the artillery wants to test fire, it still needs some preparation, not only the problem of shells, places and transportation.

There is another problem that Chen Qi can't manage, that is the problem of gunpowder.

Thinking of this, Xiao Ming left the equipment department and went directly to Lu Tong's chemical laboratory.

At this time, the chemical laboratory and the equipment department were also under the control of the guards, and everyone involved in the production of gunpowder was closely monitored.

The important things of the country should not be easily shown to others. Naturally, there is nothing wrong with this secrecy measure. These things are related to the safety of the fiefdoms.

These people are used to this kind of environment.

Compared with the production of artillery, the production of gunpowder is much easier, but Xiao Ming wants high-quality gunpowder, because Lu Tong and others' work is not easy.

A lot of powder particles will come back if they are not qualified.

In such a place, in order to avoid danger, any metal objects are not allowed to be brought in, and the tools inside are basically wooden.

To prevent gunpowder explosion.

"Your Highness, why are you here? It's too dangerous. " Lu Tong looks anxious when he sees Xiao Ming coming.

This chemical laboratory is not the one in Bowen college, otherwise Xiao Ming is worried that the whole Bowen college will be blown up by Lutong one day.

Now the chemical laboratory is located outside Qingzhou City, adjacent to the workshop area, but hundreds of meters away, and surrounded by several walls.

"You are not afraid of danger. What are you afraid of?" Xiao Ming said with a smile.

Lu Tong was stunned. He had never contacted any other vassal, but he still believed that the vassal in front of him must be different.

On the contrary, Xiao Ming was always approachable and friendly.

With a sigh, Lu Tong reacted and said to Xiao Ming, "Your Highness, part of the granulated powder you ordered has been produced."

"Yes? How many? " Xiao Ming asked with interest.

Lu Tong takes Xiao Ming through the front yard to the back yard.

When this place was designed, it was both a laboratory and a factory. The first half was a factory, and the laboratory was at the back.

There are 20 buildings of different sizes distributed in the whole area, and the functions of each building are different.

And the warehouse is also in the backyard. Lu Tong moved all the gunpowder produced to the warehouse.

When he arrived at the warehouse, Lu Tong pointed to a sack and said, "Your Highness, this is it. I don't know if it's enough?"

Lu Tong pointed to the sack, which was about half a person tall. One person was holding it. It was estimated that the powder in it was about 100 Jin."It's not enough." Xiao Ming said: "we have to speed up. If we don't have enough manpower, please tell me that I can allocate it to you at any time. We must increase the output."

Generally speaking, this ancient war lasted for a long time, and there were many times of artillery firing. This bag of granular powder was not enough for one gun.

Lu Tong nodded, "yes, your highness, I will make people speed up, but your highness, this material..."

"Not enough powder?" Xiao Ming frowned.

"Yes, the nitrates are generally from several nitrates caves in Shu, and they are not produced in other places. Just before your highness came here, Chen Bing Cao just left. He said that he bought all the nitrates in the market now, but no one sold them to Qingzhou in the future."

Lu Tong's words made Xiao Ming cool. At present, the saltpeter in the state of Dayu mainly comes from several open-air saltpeter caves in Shu.

Because it is easy to mine and the demand is not large, Dayu country does not pay attention to this saltpeter, and there are basically no special saltpeter mines in other places.

Xiao Ming once looked up the resource distribution map in the science and technology database, and there were also nitrates within his fiefdom. He also asked Qian Dafu to look for them all the time, but there is no news yet.

He can't blame Qian Dafu for this. In this era, in addition to open-pit minerals, it's easy to find them. Looking for those buried minerals is no less than looking for a needle in a haystack.

He asked Qian Dafu to look for many minerals, and now Qian Dafu has been looking for them.

Although it's very hard to live in the open, so far the harvest is very little, and there is no news about the saltpeter mine.

Now there is something wrong with the source of saltpeter, which is a heavy blow to Xiao Ming.

Seeing that Xiao Ming's face was uncertain, Lu Tong hesitated and asked, "Your Highness, do you think this is the ghost of the king of Shu?"
