Start Being a Vassal King Today - Chapter 222

[Chapter 222 Development Plan]

“What the lovers say is right with my heart!”

Zhao Heng’s brows stretched out, and a smile appeared on his face.

He also forgot for a moment.

Moreover, the tone of Dou Wei and other influential families changed, which gave him even more confidence.

So he said: “I have made up my mind, there is no need to discuss it again.”

Tie Muta’s face darkened, and the word “cannon” hurt his heart.

He went to look at the ministers again, and found that other ministers nodded one after another, seeming to agree with Liang Kai’s statement.

The intimidation failed.

“In this case, this means war, we will wait and see.” After finishing speaking, he turned and exited the hall.

Zhao Heng’s heart skipped a beat, and now he could only rely on King Yan’s artillery.

If the artillery still can’t stop Beidi’s invasion, he can only…

After all, this is also for the safety and security of tens of thousands of Dasong’s people.

With a wave of his hand, he ordered Liang Cheng to announce the dispersal of the court.

At this time Liang Kai said again: “Your Majesty, the enemy of Beidi is present, and I think that King Yan can no longer be given the right to open the sea, otherwise it will be even more difficult for the pirates to harass the northern border.”

“Liang Shangshu’s words are very true.” Dou Wei Loudly.

Han Zheng, Wang Zi’an and others came out to join in.

“It’s just that King Yan asked for the right to sea trade. If he refused, how could he sincerely send the artillery?” Zhao Heng frowned.

Liang laughed, “To tell you the truth, my Liang family was fortunate enough to master the method of cannon casting not long ago.”

“What!” Zhao Heng almost stood up from his chair.

Immediately, his face darkened, Liang Kai said not long ago, it may be a long time now.

These powerful clans actually deceived him so much.

“King Yan knows that our Liang family has artillery, so he will not cherish it with his broom, and tell him that as long as we hand over the casting method, we will persuade merchants from all states and not embarrass him in business. With the wisdom of King Yan, he will definitely not refuse. .” Liang Kai continued.

Zhao Heng narrowed his eyes.

Just now he was moved by sending King Yan in exchange for peace.

This is to praise Antai so that he can sit on the throne.

Now that he refuted the request of the Beidi envoy, King Yan naturally became an important royal force to balance the power.

He said: “I can reject the king of Yan in the matter of maritime trade, but it is not appropriate to ask the king of Yan to hand over the method of casting. Beidi’s fine work is rampant. If it is accidentally leaked and Beidi gets it, wouldn’t it be no advantage for me to praise you?” ”

After pondering for a while, he continued: “However, I will order him not to refuse you to buy his cannons. As for business matters, please don’t make things difficult for him.”

“Yes, Your Majesty.” Liang Kai hurriedly bowed back After a sentence, all faces are full of joy.

His goal was basically achieved.

Regarding the matter of sea trade, King Yan was in vain, and regarding the matter of artillery, King Yan could not refuse them either.

Although it is a pity not to get the method of casting cannons.

But he knew that King Yan would definitely not hand over such a secret.

As for business matters, it was originally up to King Yan.

If King Yan doesn’t sell their artillery, they won’t allow King Yan’s goods to pass through.

After deciding on this matter, Zhao Heng seemed very tired, and waved his hand to signal to leave.

…

Yancheng.

Military Division.

Zhao Xu was talking with Wang Ying about the cannon casting.

He sent the excerpts, since he agreed to send artillery to the capital, this must be done, otherwise it would be a crime of deceiving the emperor.

“Different?” Wang Ying confirmed it.

“That’s right, the artillery given to them is different from the one used by the prince’s family.” Zhao Xu smiled mysteriously.

Wang Ying was at a loss, “How to make it different?”

“Make white iron cannons and gray iron cannons.”

In front of the blast furnace, craftsmen were busy, some were transporting ore, some were pulling blowers, Hot air is blown into the blast furnace.

When Zhao Xu further explained how to produce iron cannons, Wang Ying was quite depressed.

Because he couldn’t understand more and more.

“Look, this is called knowing what’s happening, not knowing why.” Zhao Xu said.

Wang Ying was ashamed. Before he met King Yan, he was still very narcissistic.

I always feel that there are not many crafts in this world that I understand.

Now, he only feels that in front of King Yan, he is just a child who is not sensible at all.

“What Your Highness said is that I must listen carefully to His Highness’ lectures,” Wang Ying said.

“Puff.” Wang Chong couldn’t help laughing when he saw that his father was in King Yan just like when he made a mistake.

Wang Ying listened and glared at him, “Why? Do you know the difference between the white iron cannon and the gray iron cannon?”

“I don’t understand.” Wang Chong shook his head.

Zhao Xu smiled.

Now there is Liu Fu in government affairs and Chang Wei in military affairs.

He would have more time to spare his hands and focus on the war department.

After all, knowledge from the present is his real wealth.

These wealth will be realized in Bingzhan Division, and then bring huge wealth and security to Yanzhou.

“The section of iron has two colors, one is silvery white and the other is gray, do you understand?

” The iron that is made is white when it is cold, this kind of iron is hard but brittle.”

“Your Highness, wouldn’t it be easy to blow up a cannon made of this kind of iron?” Wang Chong showed a puzzled look.

“This is sold to the powerful family, so that Yi Yi’s chest will be blown up.” Zhao Xu said.

He hasn’t told the two of them what these two types of artillery are used for.

Wang Ying and Wang Chong heard the words, oh, and showed your majestic smile, Your Highness.

“It’s just that after we use the blast furnace, the iron produced is gray? If we want to make white iron cannons, don’t we have to use the old method to make iron? This is a bit too troublesome.” Wang Ying continued.

Zhao Xu smiled, “It’s not necessary to just blast the hot blast stove when making iron.”

In fact, the main difference between gray iron and white iron is the silicon content in the molten iron.

If the silicon content in the molten iron is greater than 4%, it must be gray iron.

This kind of iron is flexible and suitable for artillery.

Whether the silicon in molten iron can reach 4% depends on the smelting temperature.

As long as the temperature of the blast furnace exceeds 1500 degrees, under the chemical reaction, the silicon in the material will form crystalline silicon and melt into the molten iron. When the iron solidifies, it will change the crystalline form of the carbon in the iron.

Below this temperature, iron can still melt, but silicon can only exist mostly in the form of compounds, so it will become white iron after the iron piece cools.

It is because there are such complicated principles in it that he is so confident that the powerful clan can’t imitate his artillery at all.

Even white iron has high and low quality, and they can’t catch up with Yanzhou’s smelting level.

In modern times, the Qing Dynasty did not understand this before and after the Opium War, so it was still unable to create gray iron cannons comparable to the great powers.

At the same time, there is another key technical point.

White iron cannons cannot be bored.

Because it is too brittle, it will break when you drill it.

In the mid-thick period of the 19th century, high-quality artillery was basically drilled directly from cast iron, and at least one side of the bore had to be cut.

In this way, the inner wall of the artillery will be smooth, and the shells can be fired farther, even to more than ten kilometers.

This is why in the battle of Dagukou in the Qing Dynasty, the British army could directly bombard Dagukou with warships at sea.

The guns that have not been bored have flaws on the inner wall, with slight unevenness.

Although it is generally invisible, the shell will encounter resistance when it exits the barrel, reducing the power of the range.

At present, the steel guns made in Yanzhou have not been bored, so the advantage is that the blasting rate is low, and there is the blessing of granular gunpowder.

But this is basically the case, the effective killing range is only 1,500 meters, and the maximum range is more than 2,000 meters.

It would be perfect if it could be re-bored.

The maximum range of his artillery can definitely match the best artillery of the nineteenth century.

But in this way, you have to master the bore cutting technique.

The most basic bore cutting technology has two difficulties, one is the power and the other is the tool.

This tool does not mean a machete, but a variety of drill bits for processing metal on a lathe.

In terms of power, the initial boring machine used hydraulic power, which is no problem.

All that’s left is to make the knives.

In the mid-nineteenth century, knives were basically made of high-carbon steel, which is also called tool steel.

As we all know, there are soft and hard steel wires.

So this is equivalent to using hard steel to drill soft steel.

Of course, the ideal tool is hard alloy steel, such as tungsten steel.

But at the current level of Yanzhou, it is really difficult to achieve it, and it is a waste of time.

However, high-carbon steel is much easier. There is no need to add additional alloys, and a pot of high-carbon steel can be specially refined.

For him, he only seeks usability, not high-quality products.

It’s a big deal to waste a few more knives.   ”Just turn off the hot stove?” Wang Ying and Wang Chong were even more surprised, “Your Highness

, what is the reason for this?”

.” Zhao Xu said.

The two nodded, feeling like cats scratching in their hearts.

They really couldn’t figure out how the King of Yan knew such strange knowledge.

But from the bottom of their hearts, they are full of yearning for this knowledge.

I really want to master the “technology” in his mouth like King Yan.

After talking about the two cannons, Zhao Xu took a set of blueprints from Xu Lie.

“Master Wang, I will leave the cannon to you,” Zhao Xu said.

Then, he said to Wang Chong: “This king has an important task for you.”
