Chapter 37 Black technology blacksmith shop?

In the yard, Zhu Xi sat on a chair brought by the guards and waited quietly.

At the same time, he looked around from time to time, looking at everything here, and feeling strange and novel about everything.

Just then, a sound of footsteps came.

"Oh, it's an officer who came to this humble abode, I'm really shocked," a rough man exclaimed, and was startled when he saw Wang Fu dressed as a general.

"Did something happen to the shop?" The man asked cautiously, bending down unconsciously.

Wang Fu didn't answer and looked at Zhu Zhen.

The man immediately understood and hurriedly bent down in Zhu Chu's direction: "Well, sir, what can I do for you?"

Because he didn't know how to call Zhu Zhen or what they were here for, the man seemed cautious.

"I heard that your store here is for sale?" Zhu Chu asked straight to the point.

"Ah, it turns out that what the military master asked before was for you. That's right, that's right. I want to sell this shop. Now I am getting older, and the business is not easy to do, so I want to go back to my hometown. "Yes," the man relaxed a lot.

Zhu Zhen said 'hmm' and then said: "I see you have some coal, charcoal and coke here. Where did it come from?"

"Ah, um, someone transported it from Dagushan, Wanping County."

As early as the Yuan Yitong Chronicle of the Yuan Dynasty, it was recorded that coal was produced in Dagu Mountain in Wanping County.

So what this man said is reasonable.

It's just that Wanping County belongs to Yanjing, and is the land of Zhu Di, the fourth brother of Zhu Ming's fourth brother, King of Yan.

Good guy, now the three northeastern provinces are still outside the customs and are not part of the Ming Dynasty. In other words, Peiping is almost the northernmost part of the country.

And Yunnan, where Zhu Ji is located, belongs to the most southwest direction.

The distance between Zhu Chu and Zhu Di is like the two farthest directions in the country.

Can you afford the coal transported from Yanjing to Yundi?

Zhu Ming thought for a moment about his journey from Yingtian to Yunnan, and couldn't help but take a breath.

How much does this toll cost?
"Then where did this coke come from?" Zhu Zhen asked again.

He knew that coke is obtained by dry distillation of coal under high temperature conditions.

Although he couldn't remember how high the temperature was, he still wondered, did the ancients know how to refine coke?
The man laughed naively and said: "I don't remember who discovered it. During a coal use, I suddenly found some better coal left behind, so it was passed down. Is this called coke? We all call it coke. There's burnt residue. I thought it was burnt residue."

This.

Coke is made from coal.

Moreover, generally low-quality coal contains many impurities and even toxic gases. If used directly, there is a risk of gas poisoning. This is no joke.

It is recorded that in the Ming Dynasty, some officials used coal to heat their homes and died of poisonous gas.

But coke is different, because during the coking process, a large amount of harmful substances in coal have been volatilized, so the coke is basically only carbon dioxide.

It's just that the gases produced during the coking process are also very toxic.

"Actually, it's better to wash coal with water," Zhu Zhen muttered to himself as he looked at the coke pile over there.

Coal washing with water uses water to wash away some harmful substances in coal, which can at least avoid some dangers of poisoning.

Moreover, during the water washing process, after harmful substances and impurities are washed away, the combustion effect of coal can be further improved. Although it is not as good as coke, it is still much better than ordinary coal.At least it's enough for smelting.

Zhu Zhen secretly sighed, he did not expect that the technology of the Ming Dynasty had become so advanced. Not only coal and charcoal had been used, but even coke appeared.

However, the coking method of coke is probably not yet mature, so there are records that most of the coke used for smelting in the Ming Dynasty was mainly charcoal, and a small part of it used coal.

This is enough to show that the technological level of the Ming Dynasty was not bad.

Then Zhu Chu followed the man to the front yard, which was the main working environment of the blacksmith shop.

Zhu Chu saw that in the front yard, there was a modern-style traditional blast furnace.

Zhu Zhen opened his mouth wide, and his whole body felt bad.

In fact, since the Song Dynasty, the shape of the ironmaking shaft furnace has been very close to the modern blast furnace.

What's more, it's now the Ming Dynasty.

There is also a blower on the side, but it is more like a blower box than a blower.

It was a square wooden box. There was an air inlet on each side of the box. As long as you pulled the lever in the middle, you could use complex piston-like repeated movements to continuously suck in air and then send the wind force from the air outlet, which could increase the flow continuously. temperature inside the furnace.

Zhu Zhen was stunned. To be honest, the furnace in this humble and ordinary blacksmith shop may even be more advanced than the steel-making furnaces in Europe that entered the industrialization era.

Is this ancient times?Is this the Ming Dynasty?
Zhu Chu was stunned. If you had told him that this was the Republic of China period, he would not have doubted it.

"Your Highness," Wang Fu's voice suddenly sounded, calling in a low voice: "The store is still waiting for your answer."

"Huh? Oh," Zhu Zhen finally came back to his senses and said that these folk things shocked him a lot.

Because Zhu Chu couldn't understand why the Ming Dynasty's smelting technology was so advanced but still lagged behind the development of the West?

In fact, he was wrong to think so. Who said that North Korea's technology was backward?On the contrary, even if the Ming Dynasty's technology is the best in the world, it will never fall behind.

It's the people behind or the dynasties who pulled the crotch.

There were fire guns in the Yuan Dynasty, and they were modified from the sudden muskets of the Song Dynasty. Even Zhu Yuanzhang's fire gun technology was also good.

Even from the Ming Dynasty to the Yongle period, a special Shenji battalion was set up, which was a unit that specialized in using firearms.

The toothbrush was also invented in the Ming Dynasty.

There were actually a lot of black technologies in the Ming Dynasty, especially after Zheng He's voyages to the West, he brought back a lot of technologies and even talents from abroad, including the glass he wanted to make now. After Zheng He brought back a group of glass-making workers, Mass production began in the Ming Dynasty.

So Zhu Chu needs to tighten his grip, because if he doesn't come up with glass soon, I'm afraid he won't be needed to 'invent' it.

"Then I'll buy your store," Zhu Zhen looked at the man and decided to buy the store without any hesitation.

The man was immediately overjoyed, and hurriedly rubbed his hands and asked, "How much do you plan to bid?"

"Oh? How much do you want?" How could Zhu Chu know what a reasonable price should be, so he asked the man and asked him to bid.

The man thought for a while and said with a sincere face: "I am in a hurry to return to my hometown. How about this, 500 taels, including the unused coal and charcoal in the backyard, as well as the unsold farm tools and stuff." There is also a lot of iron ore in the house.”

Zhu Ming didn't even hesitate and said: "Deal, Wang Fu, go find Mr. Li to get the money."

He didn't have any money with him, not to mention 500 taels, not even [-] taels.
