Chapter 156: The Birth of Artillery

Yanguan. Read М

Mozi stared at Kutu and the other two with an expressionless face.

After receiving the news of Kutu's arrival, he was very calm because he was sure that the court would surrender.

At present, Dasong was in turmoil, and powerful enemies on all sides continued to encroach on Dasong's territory, and the royal guards were unable to resist.

In the northwest and southwest, they could only rely on the powerful tribes' army to resist.

And this made the powerful tribes' army stronger.

So he knew very well that the emperor would not start a war with Beidi for Kutu and the other two.

"You can go back to the grassland." Mozi said.

The city gate had been opened, and the land outside once belonged to Ningjindusi.

And now it belongs to Beidi.

"Hahaha..." Chaerha and Tam laughed wildly.

Kutu did not laugh. Even if he returned to the grassland, he was still a shame to the grassland.

This sudden sense of shame made him hate the King of Yan to the bone.

Yes, he would go back even if he was ridiculed.

Even if he only became a wolf record after returning, it would be fine.

He was going to return to Yan County again and personally end the life of the King of Yan.

Passing through the city gate.

He strode towards the welcoming cavalry.

Mounting his horse, he looked back at Yanguan and rode towards the army.

Not long after Kutu left, the Northern Di army began to move.

They slowly moved northward and disappeared into the skyline, as if they had never appeared.

"Finally gone." Xiao Yuanshan laughed.

Mo Di snorted coldly, "Don't you feel ashamed?"

Upon hearing this, veins on Xiao Yuanshan's neck suddenly popped up. He looked at Mo Di with resentment and said angrily: "Mo Di, you are the commander today. I accept this, but you can't always be the commander of Yanguan."

After saying that, he turned and left.

Behind him was the Xiao family. In the court, the Xiao family and the Dou family joined forces and had been trying to get him to replace Mo Di as the commander of Yanguan.

So, he was not afraid of Mo Di.

Mo Di ignored Xiao Yuanshan. He looked to the north again with a hint of worry in his eyes.

He had an ominous premonition that the time for the Northern Di to move south was getting closer and closer.

If Yanguan was broken, who would be able to turn the tide?

He turned his head to the west.

In Yanzhou, the Yuan family could not be relied on, and only the King of Yan might be able to fight the Northern Di.

He knew that the King of Yan had nowhere to escape and no way to retreat. If he lost his fiefdom, he would be dead, and he had no choice but to fight to the death.

This was also the reason why he asked Mo Yu to serve under the King of Yan.

The King of Yan was like a spark, although weak, but burning persistently.

…

"Is this the method of making artillery?"

In the study room of the palace, Wang Ying held up the drawing like a treasure.

The drawing showed the complete process of making artillery.

The King of Yan always liked to show him the craftsmanship in the form of pictures.

This was not only intuitive but also easier to understand.

"You go back and prepare now, and tell me when you are ready." Zhao Xu said.

The production of artillery was just a matter of time, and now he was as full of expectations as Wang Ying.

He felt the anger of the generals yesterday.

Although he tried to persuade them, he still felt unhappy.

After all, he had been in this world for so long and gradually integrated into this world.

The national enemies and family hatreds were no less than theirs.

Moreover, he was facing a real threat to his survival.

Looking around, there were enemies on all sides.

He had no way out, so he had to keep making himself stronger.

"Yes, Your Highness." Wang Ying went happily.

The next morning.

Wang Ying came to the palace again, and the Armory was ready at this time.

He washed and dressed with the help of Feng'er and Luan'er.

After a simple meal, he got up and went to the Armory.

In the Armory, Zhao Xu saw that the craftsmen had erected all the iron molds.

There were a total of nine complete iron molds.

In the blast furnace area for iron smelting, the craftsmen were extremely busy.

The Armory bought a large amount of iron ore in the past two days.

It was prepared for this day.

The steel required for a cannon is enough to make a hundred plates of armor.

"Your Highness, these are rice husks ground into powder, these are washed fine sand, and these are coal powder."

In front of the iron mold, Wang Ying pointed to the things in the wooden box, which he prepared according to the text on the picture.

They are needed before pouring.

Zhao Xu leaned over and grabbed a handful of rice husk fragments.

These fragments were ground very fine, almost like dust.

He looked at the sand again.

These sands were finely sieved, and the coarseness and fineness were roughly the same, and the carbon powder was the same.

"Let the craftsmen brush it on." Zhao Xu said, he was very satisfied.

These things have to be brushed on the inside of the cannon mold, so they must be even.

Wang Ying heard this and gave orders to the craftsmen.

At this time, the craftsmen mixed the rice husk powder with lard and brushed it for the first time.

The second time, fine sand was used to prevent the cannon body from sticking to the iron mold.

The third time, the craftsmen brushed carbon powder for carburization.

After pouring the molten steel, some of these carbons will be integrated into the molten steel, increasing the carbon content of the outer layer of the molten steel.

As we all know, steel is actually iron with a carbon content within a certain range.

The higher the carbon content, the harder it is.

In this way, the cannon is hard on the outside and soft on the inside.

The purpose of the soft inside is to allow the cannon to better withstand the explosion of gunpowder.

Because it is too hard and easy to explode.

The hard outside is to prevent the cannon from deforming, otherwise the cannon will swell at the tail when it explodes, just like a balloon.

In the contemporary Ming Dynasty, there is a copper core iron body cannon that uses this principle.

However, this kind of cannon is more troublesome to make and is far less suitable for mass production than the iron mold cast cannon.

After the craftsman finished painting, Wang Ying went to check it carefully and asked the craftsman to fix some flaws.

He was particularly strict in production.

After that, Wang Ying asked the craftsman to put the iron mold together and hoop it with an iron hoop to form a cylinder.

He also asked the craftsman to light a fire to heat the iron mold to prevent the outer layer from cooling too quickly when pouring molten steel, which would affect carburization.

After all these preparations were done, Wang Ying asked the craftsman to take the mud core and stuff it into the iron mold.

The thickness of the mud core is the width of the muzzle.

After the casting is completed, just crush the mud core.

"Cast molten steel." Everything was ready, Zhao Xu nodded to Wang Ying.

Wang Ying immediately shouted loudly, and his voice was even a little out of tune.

He was excited. It was not impossible to make such a sharp weapon and leave a name in history in the future.

The craftsmen received the order and carried the crucibles on the left and right sides to the earthen platform. The left side slowly poured the molten steel and then withdrew, and the right side began to pour.

Another craftsman climbed up on the left, and he poured after the right one was finished, so as to maintain continuity.

The rolling molten steel flowed down, and the air seemed to be hot at this moment.

The craftsman who lifted the molten steel was sweating profusely.

When the molten steel was flush with the muzzle, Wang Ying stopped the craftsman who was casting.

The next step was to wait for the cannon to cool down naturally.

Carburizing has a process, and artificial accelerated cooling will make carburizing incomplete, affecting the quality of the cannon.

It was not until the evening that the cannon completely cooled down, and Zhao Xu immediately asked people to remove the mold.

The iron hoop was smashed, the craftsman took away the iron mold, and the mud core was chiseled off, and the barrel was cleaned, and a real cannon was born.

This cannon is not the fire gun used by Beidi and Dasong, and its power will definitely make his enemies very happy.

Next, it is time to test the power of the cannon.
