The edge of Zhuangzi, the edge of the iron-making test site.

A slightly strange blast furnace appeared in the original clearing.

"It's done today!" A middle-aged man wiped the sweat from his head, breathed a sigh of relief, looked at the stove in front of him with satisfaction, and kept comparing the atlas in his hand.

"Master, the construction is finished, but ...... Can you really make iron? We've never seen a stove like this before! A young man looked at the stove in front of him and expressed doubt.

"Ah He, you only know how to work with a boring brain, do you understand the drawings given by Chu Anjun?" The middle-aged man was dissatisfied and looked at his apprentice, "So lazy, can you be worthy of the wages of these days?" ”

Youth:......

"The blast furnace drawings given by the female monarch are cleverly designed, if they can really be realized, the art of frying steel will be gone forever, and they will be ...... Uh, yes, the method of filling steel has been replaced, do you understand? ”

"Yes, yes, what my Master Puyuan said is right, and what the female monarch said is also right." The youth shrugged.

"Go, tell the lady that the blast furnace has been built, and you can test the furnace today."

"Oh."

……

Inside the study.

"Mother~" Huang Yueying is coquettish with her old mother.

She had forgotten about school uniforms and work uniforms, and someone had to take care of them...... But she really doesn't have anyone in her hands.

Chua: ......

"You, crying in the morning, have aroused your grandmother at this time! Anyway, my mother will help you this time, and then I will go to find your aunts and sisters-in-law......"

Huang Yueying responded with a smile, "Thank you, Mother!" ”

In this era, female red is a woman's basic skills...... Oh, she doesn't count. She felt that she really didn't have the patience to deal with needlework.

Huang Chengyan shook his head and smiled helplessly, he believed that if there was a place where he could be used, his daughter...... It will also be unceremonious.

Coincidentally, shouts came from outside the hospital.

"Xiaomin Liu He, ask to see Chu Anjun."

……

Liu He stood at the door of the third family, and did not rush in, but just carefully looked at the big three-entry courtyard.

Surrounded by bamboo fences, not far from the main entrance is the main hall of the front yard, and he knows that with his identity, there is no chance to sit in the main hall of others.

Then he shouted, "Xiaomin Liu He, ask to see Chu Anjun!" ”

Not long after, Liu He saw Huang Yueying, who was wearing a light cyan military uniform and long hair, looking quite refreshing and neat.

"Liu He?" Huang Yueying saw the man in coarse cloth in front of her, and recalled, she remembered that this was the apprentice of the blacksmith Pu Yuan, "Is there something wrong?" ”

"Chu Anjun, the blast furnace has been built, the master said, you can test the furnace today." Liu He said.

"Done?" Huang Yueying was a little surprised, and glanced at today's time again, it was already afternoon, and in two or three hours, it would be dark.

Practicing a furnace of iron, this little time is not enough.

Operate in the dark, after all, it is too dangerous.

Ironmaking is not papermaking.

And many people in this age have night blindness.

"Yes, it's already done." Liu He pointed to the remote corner.

Huang Yueying looked over, and then nodded, "It's hard work, please tell Master Pu Yuan, tomorrow morning, test the furnace!" ”

"Early tomorrow morning?"

"Well, it's going to be late today, the time is insufficient, the operation is inconvenient, and the danger is great." Huang Yueying explained seriously, "If there is nothing to do today, let Master Pu Yuan take everyone home early to rest and get off work!" ”

Liu He: ???

"Girl-kun...... This ......"

"Go ahead."

"No."

Liu He was a little surprised, and then turned back.

He didn't quite want to understand it, and it was clear...... When the girl gave her master the drawings, she said that she should build Yunyun as soon as possible...... Now that it has been built, this lady is not in a hurry.

Strange and weird.

If you can't figure it out, you won't want to.

At this point in time, I can get home earlier, or ...... What about having dinner first and then going back?

Let's eat dinner first, although there is no pork meat today, there are also chicken and tofu!

……

When Gan Ning returned to the village, he saw that there was no one on the side of the iron-making experimental workshop, and then he also saw the blast furnace that looked very strange, and he didn't think about it, so he rode his horse to Huang Yueying's house.

It just so happened that a family of three had dinner, and Gan Ning's stomach screamed, and she was tired from running around for a day...... He was hungry too.

greeted Huang Chengyan and Cai's family, and then handed over the booklet of today's investigation to Huang Yueying, and hurriedly went to the workshop canteen to eat.

Huang Yueying: ......

"Open it and see?" Huang Chengyan spoke.

In fact, you don't need to look at it, he also knows the people around here very well.

Wealthy, not much.

More must be the poor.

Huang Yueying nodded, and opened the booklet, today Gan Ning and others visited more than 140 households, this efficiency is already very high.

Because, in today's convoy...... There are not many people who can read.

Not to mention documenting.

Among the more than 140 households, there are 30 families, and the important workers in the family are sick; There are fifty households, and the food in the house is almost at the bottom; Most of the rest have only enough food for ordinary people for two to four months, of course, if they are mixed with wild vegetables...... If you eat less every day, you can last longer.

There are only a few families, and the grain stock is enough to last until the autumn harvest.

Shocking.

However, this time she was not as confused as she was in the morning, so she looked at Huang Chengyan, "This time I want my father to help." ”

Huang Chengyan: ...... He knew he couldn't escape.

"Say it." Huang Chengyan was helpless and put down his chopsticks.

"It is mainly the 30 families who are sick with labor, scattered in various villages, and I bother my father to go to the county seat, invite five doctors, and see them, and most importantly...... Bringing together medical cases. Huang Yueying thought for a while and said.

Yes, she asked for a medical case.

After all...... There are too many things in my head, and there is a barefoot doctor's booklet for a special period, as well as other booklets related to Chinese medicine. Now there is no Western medicine, but Chinese medicine, she has to have a good pair.

It's not that I don't trust today's doctors, but I just want to establish a complete logistics system.

In addition, Huang Chengyan is erudite in ancient and modern times, and he has read a lot of medical books, but his old father has not really shown people to be sick.

"A medical case?" Huang Chengyan was a little puzzled, but he didn't object, and nodded, "I'll go tomorrow." ”

"Thank you, Father."

"Does Achu really think that you are the only one who cares about all the people in the world?" Huang Chengyan smiled, "Eat." ”

"Hmm!"

……

Early the next morning, Huang Chengyan went out, and the Cai family organized the women of the village to tailor clothes for the children of the clan and the workers in the workshop.

As for copying books, they can only be put first.

And Huang Yueying pulled Gan Ning to the direction of the iron-making test furnace.

Pu Yuan rubbed his rough hands excitedly, looking at the towering stove and the high platform built next to the stove.

Today we will open the furnace for testing, and if it really happens...... According to the female monarch, 100 steels can also be produced on a large scale!

I looked at the pile of "coke" next to the iron ore that had been refined several times, and the female monarch's brochure said that this furnace must use this "coke" to make iron.

"I've seen the female monarch!"

"I've seen General Gan!"

Seeing Huang Yueying and Gan Ning, Pu Yuan took a group of people to salute.

"Master Pu, everyone, don't see each other." Huang Yueying smiled, and then saw the preparations around her, and knew that she could test it.

Still, she had to check it out.

So, inside and out, the blast furnace was shown inside, the functional areas in each position, as well as the position of the blower and taphole, as well as the forged steel channel next to it...... It's all in place.

She didn't expect that Pu Yuan would really restore this stove to the same level.

"Master Pu, let's get started."

"No." When Pu Yuan got the order, he said loudly, "Test the furnace!" ”

"Test the furnace!"

……

Gan Ning looked at all this, "This is the big gift that Achu wants to give to his brother?" ”

"Exactly!" Huang Yueying nodded and smiled, "If it is successful, the escort team will not lack armor and weapons." ”

"Really?"

"When did Achu deceive his brother?"

Gan Ning then smiled, "When we first met. ”

Huang Yueying: ......

"At that time, I was walking outside, and I had to do it as a last resort."

"Yes, yes, what Achu said." Gan Ning shook his head helplessly, and waited patiently.

Until...... A few hours later.

Gan Ning saw the silver-white molten iron flowing out of a hole under the blast furnace!

The molten iron flowed into the groove called the wrought steel trough, and several pieces of iron stood up in it.

"Achu, why do you put iron pieces?"

Huang Yueying thought about how to explain the relationship between pig iron, wrought iron and 100 steels to Gan Ning.

"General Gan, the female monarch said, what we have practiced here is pig iron, which ...... Well, the impurities are higher, and it is also the main use of iron in our Han Dynasty now, and if you want to build weapons, you need to temper pig iron. Pu Yuan smiled, took over the topic, and wiped the sweat from his head, "Only then did we have a hundred steels." ”

"Indeed, the blacksmiths also use iron to make iron." Gan Ning thought back.

"Nujun said that 100 steel is actually because after the pig iron is hammered and refined, the impurities in it are constantly discharged, and a few pieces of iron in the forging steel groove are iron pieces after forging countless times, and the impurities are less than 100 steel, which is called wrought iron."

"Wrought iron is hard, but it is extremely brittle. I've tried it in the next place, and it does. ”

In this way, after the pig iron and wrought iron are mixed, due to the high temperature of the molten pig iron, the wrought iron will be melted quickly...... What comes out is steel! ”
