Become a feudal king from today

“Quartz sand, soda ash, limestone.

Wang Chong read the words on the paper and scratched his head, his mind was blurry.

The only thing he knew about the contents was limestone.

It is used in iron making and calcining cement.

Zhao Xu knew that Wang Chong could not understand this thing.

So he said: "This quartz sand is similar to the sand by the river, but this sand is white."

"White sand? Your Highness, I have seen this thing before. When I traveled with my father, I passed through Liao County. The lakeside there was filled with this kind of sand. Was it still strange at that time?" Wang Chong thought about it carefully and suddenly remembered .

"Liao County, indeed, it is an important producing area for this kind of sand." Zhao Xu smiled and nodded.

The knowledge in his head is genuine.

And after living here for such a long time, he basically grasped the contemporary equivalent of the administrative division of Dasong.

This Liao County is equivalent to the vicinity of Lingshan County in contemporary Hebei Province.

In contemporary times, this place is a famous quartz sand producing area.

Therefore, Wang Chong said that he was not surprised at all when he found this kind of sand in Dai County.

"Well, it will be easy to obtain the raw material glass." Zhao Xu said to Wang Chong.

Liaojun belongs to Yanzhou and is not very far from Yanjun.

If the merchants knew that this kind of unwanted sand could be sold for money, they would definitely go to Liao County to transport the quartz sand to him.

"Your Highness, what is this soda ash?" Wang Chong asked again.

Now that two of the three raw materials have been solved, as long as we understand the soda ash, we can make glass.

"It's the kind of white powder used to steam steamed buns." Zhao Xu said.

Soda ash has a long history in ancient times. At first, people obtained soda ash from shells and plant ash. After the discovery of trona ore, it became popular on a large scale.

Soda ash is commonly used in the production of various types of pasta in the north, so soda ash is more widely used.

"So it's this." Wang Chong understood. He looked at the method of melting the three raw materials on the paper and nodded slightly, thinking that he could try it.

"Quartz sand is in Liao County and soda ash is in Yuzhou. Before letting businessmen go to these two places to purchase raw materials, you can build the regenerator in the picture." Zhao Xu added.

Dasong's Yuzhou is equivalent to contemporary Henan.

In Wucheng, Henan, there is one of the largest open-pit trona mines in the country, with reserves of hundreds of millions of tons.

He asked Yang He and found out that all alkali dealers in Yanzhou bought their alkali from this place.

In this way, there is quartz sand in Liao County and soda ash mine in Yuzhou.

In this way, the raw materials for making glass are not a problem.

"Your Highness is really knowledgeable and knows everything." Wang Chong's eyes were filled with admiration.

Just quartz sand, King Yan actually knew where to buy alkali.

This really saved him a lot of time.

Zhao Xu laughed twice without explaining.

Instructing Wang Chong to prepare for making glass, Zhao Xu left the military division and headed for the northern camp.

Last time he was in Shanggu County, he mentioned that he would establish a school in the military. He did not just say it casually, but he must implement it.

One of his purposes for doing this was to improve the general's combat quality.

The other is to strengthen his prestige in the military.

With the emergence of artillery, the destructive power of the royal army also increased.

He must keep such an army firmly in his hands. He doesn't want his army to turn its guns on him one day.

Arrive at the camp.

Soldiers are training under the command of generals at all levels.

Chang Wei rode a horse to inspect the camp.

Seeing Zhao Xu arriving, Chang Wei rode over.

"Your Highness." Chang Wei got off his horse and saluted.

"No courtesy." Zhao Xu nodded.

He looked at the soldiers in the field who were sweating profusely from training. He did not mention the school immediately, but asked: "Have you figured out how to use artillery on the battlefield?"

After the artillery was built, he never told Chang Wei how to use the artillery on the battlefield, but let him think about it himself.

After all, what you come up with is more profound.

But if what Chang Wei thought was unreasonable, he could only show it to him.

When asked this question, Chang Wei became a little less confident than ever.

If it comes to the battle formations he usually trains, he is not afraid of whoever is chosen from the Dasong Army.

But it was the first time for him to get into the sedan chair as a big girl.

"The general thought it should be used similar to a fire gun. Before the battle, he placed the artillery at the front and fired a few shots at the enemy." Chang Wei said.

Zhao Xu frowned when he heard this.

He felt that he had overestimated the ancient generals' knowledge of firearms.

But Chang Wei cannot be blamed for this.

After all, in the contemporary Ming and Qing Dynasties, artillery was also used in this way. Just like bows and arrows, it only fired three shots at a time.

"Wouldn't it be impossible to use the artillery's advantage in this way?" Zhao Xu asked, "Furthermore, if the opponent's cavalry rushes through and nails the holes in the gun, wouldn't you be blinded?"

Chang Wei was startled when he heard this. If the powder hole behind the artillery was nailed, the artillery would be useless.

At this time, he looked at Zhao Xu.

The artillery was made by King Yan, and he believed that King Yan would definitely know how to use it.

For him, face is not important, but being able to learn something is important.

So he asked with a playful face: "Your Highness, please give me some advice."

Zhao Xu nodded and said solemnly, "But before we do it again, there is something very important that you need to do. This matter must be promoted to the entire army. In this way, both you and the general will benefit."
