Datang: Time travel in two months, wait online, hurry up!

When Duan Lun heard that it was indeed the three-piece suit, he was overjoyed!

Since yesterday afternoon, his wife, Li Ke's aunt, Princess Gaomi, and her daughter have been talking to him about tea and soap!

The princess was very dissatisfied with him for not being the first to get the tea and soap.

He was kicked out of the bedroom yesterday, and the door was tightly closed!

And threatened, when will he get these two things, when will he be able to enter the bedroom!

If it was someone else, maybe I could argue with my wife a few words.

But he didn't dare to argue with the ancestor at home. After all, he was a son-in-law, and he was always famous outside and humble at home.

If the princess was upset and went to the palace to find Li Shimin, his younger brother, to sue him, then he would not be able to stand it.

So I could only sleep in the study all night with a sad face, thinking that after welcoming Li Ke today, I would go to Li Xiaogong's mansion to ask where I could get these two things.

Unexpectedly, Li Ke actually gave him a copy!

How is this not a timely help?

The way he looks at Li Ke now, apart from being close, he also feels more grateful!

"Thank you His Highness King Wu!"

Lu Yigong is also very grateful to Li Ke.

Although his situation is better than Duan Lun's, after all, his wife is not a princess, but it's not much better.

If he didn't get these two things today, he might have to sleep in the study like Duan Lun.

"Just be careful, as long as Uncle and Master Lu like it."

As soon as Li Ke saw the excitement of the two, he couldn't help shaking his head and smiling.

Good guy, it seems that these two people were educated by their wife at home yesterday!

It seems that the family has given a death order, otherwise why would I be so excited.

Later, Duan Lun and Lu Yigong briefly introduced to Li Ke the functions that the Ministry of Industry is responsible for, how many craftsmen it has, and what projects are currently underway.

He told him all the affairs of the Ministry of Industry in detail, which also gave him a general understanding of the Ministry of Industry.

In the morning, Li Ke walked around the office of the Ministry of Industry, familiarized the officials of the Ministry of Industry, and let them know that the Ministry of Industry had his own servant.

After eating at noon, he went directly to the workshop where the craftsman was.

The reason why he took the initiative to come to the Ministry of Industry was not for any position, but for these craftsmen!

You must know that in this time and space, Datang is the most powerful and technologically advanced country in the world!

In Datang, the most technologically advanced place is the Ministry of Industry!

The core of the Ministry of Industry is that the best craftsmen of the entire Tang Dynasty are gathered here!

It is not an exaggeration to say that this is the ceiling of Datang technology!

Perhaps for others, a craftsman is just a craftsman with a higher status than a merchant.

But in his opinion, every craftsman in the Ministry of Industry is a difficult talent!

And the gathering of so many craftsmen is a valuable asset!

"¨. Met His Royal Highness King Wu!"

When the supervisor in charge of the iron-making workshop saw Li Ke coming, he immediately knelt down and saluted respectfully.

Although he has never met Li Ke, he has also received news that Li Ke will serve as the left servant.

Li Ke's clothes, which can only be worn by a prince, already showed his identity.

"Call all the craftsmen over for a meeting!"

Li Ke didn't waste time and asked him to call the craftsmen over.

Soon, all the craftsmen of the iron workshop arrived.

Li Ke took a look and found that his skin was dark because of iron smelting all year round, and his clothes were soaked in sweat because of the high temperature.

"This king is now serving as the left servant of the Ministry of Industry, responsible for supervising the construction of Quyuanli and bobbins. Next, we need everyone's cooperation."

Li Ke first told everyone about the next main task.

"His Royal Highness, please rest assured, I will definitely do my best to complete the task assigned by King Wu!"

Everyone replied respectfully.

"This is the blueprint. Take a look, how much can you build in a day?"

Li Ke handed them the drawings of Quyuanli and the bobbin car, and then asked about the output.

"The villain estimates that Qu Yuanli can make fifty of them a day, but it is more difficult for the bobbins, maybe ten of them a day."

The little supervisor glanced at the drawing, and after careful consideration, he gave Li Ke an answer.

"so little?"

Hearing this number, Li Ke couldn't help being slightly taken aback.

He didn't expect that the dignified Ministry of Industry, where the top craftsmen of the Tang Dynasty gathered, could only make fifty Quyuanli in a day?Ten bobbins?

"Going back to His Highness King Wu, this is already the fastest speed."

The little supervisor smiled bitterly: "Although there are many craftsmen in the Ministry of Industry, there are also many projects to be responsible for. In fact, there are not many people in each workshop."

"Although the Quyuan plow has a simple structure, it still needs to be hammered into shape. This can only be done by hammering it manually."

"The most important thing is that the amount of iron is limited, and other departments also need iron, but the daily amount of iron smelted by the Ministry of Industry is so much, so"

"Although the material required for the bobbin car is wood, but because of its complex structure and large size, the speed will be very slow."

The little supervisor quickly explained to Li Ke why the output was so low.

"I see."

After listening, Li Ke suddenly understood.

He used to think of later generations, but he never thought about it. In this era, everything actually needs to be made by hand.

Moreover, both human resources and iron resources are very limited!

"It seems that the first step is to improve the ironmaking technology and greatly increase the output of ironmaking and steelmaking!"

Li Ke slightly modified the plan, and planned to increase the production of steel first!

PS: Fourth more! .

Chapter 75 Coke Steelmaking!Assembly line work!

He has a lot on his mind about advanced iron and steel making technologies.

There is no opportunity to experiment in modern times, but in Datang, it is natural to experiment as you want.

Moreover, he is now the left servant of the Ministry of Industry, so there is no problem in making steel and iron!

If he does not have the position of Minister of Industry Zuo Shilang, but is just a simple king of Wu, then he cannot make iron!

Because smelting iron can make weapons!

If a prince like him smelts iron privately, it would be hard not to be identified as wanting to make weapons.

A prince builds weapons privately, what do you want?

At that time, there is no need for Changsun Wuji to frame him, and Li Shimin will clean him up by himself.

But now, as the minister of the Ministry of Industry, what happened to me making iron and steel?

That's my job in itself, okay?

I have smelted more steel, not only will I not be punished, but I will also be rewarded by Li Shimin!

This is to legalize things that were originally illegal!

"Then before building Quyuanli, let's upgrade and improve the iron-making process!"

Li Ke thought for a while and said to everyone.

"Upgrade and improve the ironmaking process?"

The craftsmen in the workshop all looked at each other in blank dismay, looking at Li Ke with doubts and puzzlement in their eyes.

Can the ironmaking process be upgraded and improved in a day or two?

King Wu doesn't understand anything!

"His Royal Highness King Wu, the upgrade and improvement of the iron-making process cannot be achieved overnight. It requires a long period of technical accumulation, and then the improvement will come naturally."

An old craftsman stood up and explained to Li Ke: "I'm afraid it's not realistic to upgrade and improve the ironmaking process in a short period of time."

When the junior supervisor at the side heard the old craftsman's words of not saving Li Ke's face so bluntly, he was frightened into a cold sweat.

You know, this is the prince!

And now he is still the official Zuo Shilang of the Ministry of Industry, and he is their immediate boss!

If this annoys Li Ke, they will definitely have a hard time!

"What you said has some truth, but not quite right. 8"

Li Ke didn't mind the old craftsman's straightforward words, but argued with him.

"There is a saying that if I read a book a hundred times, its meaning will be self-evident. It means that as long as I read a book enough times, I can understand the truth in the book."

"It's like what you said, after a long period of technology accumulation, the technology will improve naturally."

Li Ke suddenly changed the subject and continued: "Then have you ever thought that I will understand the truth while reading this book, maybe I don't need to read it a hundred times, but only need to read it ten times to understand the meaning of the book. Does it make sense?"

"In the same way, why do I have to wait for a long time to accumulate technology? Why can't I think about how to improve the efficiency of iron making while making iron?"

"Perhaps it won't take long to find a way to increase iron production."

Li Ke did not put on airs as a prince, but seriously presented the facts and reasoned with him.

"Can this be the same?"

When the old craftsman heard his words, he didn't know how to refute for a while, so he could only say something dryly in a low voice.

"It's like although I have never been in contact with iron smelting, I also know that the important condition for iron smelting is high temperature!"

"As long as the temperature in the iron-smelting furnace is high enough, the iron ore can be melted faster and the iron in it can be smelted into molten iron."

"After the furnace temperature becomes higher, not only the iron-smelting speed is faster, but also the smelted iron has fewer impurities and higher quality."

Li Ke continued to speak with a calm expression.

"But how to increase the temperature of the furnace? The temperature of the blast furnace will drop immediately."

The old craftsman saw that Li Ke didn't look like a pure layman, at least he knew something, so he couldn't help asking.

"It's very simple. First heat the air to a high temperature, and then blow it in. Not only will this not lower the temperature of the furnace, but it will also make the flame burn more vigorously, thereby increasing the temperature of the furnace!"

Li Ke glanced at him and answered the question in a calm tone.

"Heats the air and blows it in"

Hearing Li Ke's words, the old craftsman couldn't help being taken aback for a moment, then his eyes widened, as if he had been struck by lightning, he stood there motionless, as if he had been frozen!

"Yes, why didn't I think of a way to heat the air in advance?"

The old craftsman suddenly realized, and then he started talking to himself loudly with great excitement.

What Li Ke said just now seemed to have reopened a door for him, allowing him to see a high-yield and high-quality iron-making road!

"His Royal Highness, forgive me for being blind just now!"

The old craftsman immediately knelt down respectfully to Li Ke, and apologized to Li Ke convincingly.

Just now he really regarded Li Ke as a layman who didn't know how to do it, but now it seems that he, who has been refining iron for decades, looks like a layman!

After all, he has been smelting iron for decades without thinking of heating the blast. Li Ke put forward this idea as soon as he came. This is the gap!

After hearing Li Ke's words, the little supervisor and other craftsmen also thought about it for a while, and then looked at Li Ke in surprise.

Because they thought about it according to the method Li Ke said, and it seemed that it was really possible!

"Not only that, but the height of the blast furnace can also be increased, so that the furnace temperature can be raised again!"
