Zhao Yanhuan took a few pieces of coal, burned them, and determined that they were coal.

There are so many coal mines that don't need to be dug in this coal mine, which shows that the coal storage is very large, enough to support her for a long time.

When Zhao Yanhuan inspected the coal mine, there were many people around who came to pick up coal with baskets on their backs.

The ancients also knew how to use coal for heating, dating back to 3,000 years ago.

In the early days, people called coal as Shini, and later there were more names such as carboniferous, graphite, and stone, in short, the history of human use of coal is very long.

These people are so close to the coal mine that they will definitely not let go of coal, a useful fuel.

It was determined that this was a large coal mine, and Zhao Yanhuan immediately bought this large piece of land.

Then recruit the nearby people to mine coal on the spot, because this work is very hard, so Zhao Yanhuan gave a lot of money, and also included three meals and accommodation, which attracted hundreds of people to work at once.

With coal mines, it also has to go through coking before it can be used to make weapons, coal contains sulfur, and coal is used directly to make iron, and the iron will be very brittle.

After the coal is coarched and then the iron is struck, you can get very strong and useful weapons and armor.

With enough sharp weapons, strong armor, and enough horses and enough food, then everything is ready and waiting for the opportunity.

This arsenal, Zhao Yanhuan chose to build it in a col in the deep mountains, and the person who managed it at the same time, after thinking about it, Zhao Yanhuan chose to let her fourth uncle Zhao Yicang be in charge.

Although Zhao Yicang has a jumpy personality, he is actually very reliable, and he has never made a mistake in what he is asked to do.

Zhao Yicang has been accompanying the Zhuang family to manage everyone's farming in Qipai Village, but now that the Zhuang family has been trained, he should be able to take charge of himself.

Besides, there is Zhao Huaer accompanying the Zhuang family, so Zhao Yanhuan wrote directly and asked Zhao Yicang to come to Yi'an Prefecture.

Originally, I just wanted Zhao Yicang to come, but I didn't expect that when Zhao Yicang came to Yi'an Prefecture, even Zhao Huaer came with him.

Seeing Zhao Yanhuan, Zhao Hua'er said directly: "Sister, my mother said that she should stay in Qipai Village alone, let me come with the fourth uncle to see what can be done." ”

Zhuang didn't think much about anything in the past, just cooking, and didn't think that there was any difference between Zhao Huaer and not following Zhao Yanhuan's side.

But now that she has started to take care of things, she thinks about it a lot, she knows that Zhao Yanhuan is going to do great things, and at this time, the people who follow her can be reused, and they can get more benefits in the future.

Although it is a family, the Zhuang family has no bad intentions towards Zhao Yanhuan, and even she has placed herself in the position of Zhao Yanhuan's subordinates in advance, and never puts the score of the elders in front of her.

However, this does not prevent the Zhuang family from being selfish and wanting to let his daughter get more and better treatment.

When Zhao Yanhuan saw Zhao Hua'er, she understood Zhuang's thoughts, she didn't dislike Zhuang's selfishness, those who were not selfish were saints, everyone was a layman, and it was normal to have selfishness.

So Zhao Yanhuan said directly: "Then you can help me take care of the grassland." "Zhao Yanhuan has always let the herdsmen take care of the cattle and sheep, the horses and horses, and let her mother Li Qing handle all kinds of chores.

But Zhao Yanhuan then planned to open a special class for studying medicine, so that Li Qing could systematically train a group of doctors and nurses.

In this way, Li Qing has no skills, on the grassland side, he has to find someone to take care of it, Zhao Hua'er has been by his side for a long time, Zhao Yanhuan knows that although Zhao Hua'er is silent, his ability is not weak.

Sure enough, Zhao Hua'er didn't have any embarrassment and said, "Okay, then I'll go to the pasture." ”

Zhao Hua'er has always done things quickly, and this time it was the same, Zhao Yanhuan said here that she would take care of the grassland, Zhao Hua'er didn't delay for a moment, and immediately went to the grassland.

Zhao Hua'er left, Zhao Yicang came over and said to Zhao Yanhuan with a smile: "Yanhuan, Hua'er is going to take care of the grassland, then you want the fourth uncle and me to take care of somewhere." ”

Zhao Yanhuan didn't smile, she looked at Zhao Yicang with a serious face: "I want you to help me manage the arsenal with the fourth uncle." ”

Arsenal, as soon as I heard it, I knew that it was a place to build weapons, and Zhao Yicang, who had always been out of character, immediately became serious when he heard this.

Zhao Yicang didn't feel that he couldn't manage the arsenal well, he just assured Zhao Yanhuan: "Don't worry, I will definitely manage this arsenal for you, and nothing will go wrong." ”

Zhao Yanhuan nodded and said, "I will transfer 3,000 people from Qipai Village, and let them be responsible for following the fourth uncle to build an arsenal in the deep mountains, and at the same time serve as the guard of the arsenal." ”

"I've been preparing the people who forge weapons all these years, and this time it's just right to use, and in order to prevent leaks, their families have to live together in the arsenal."

Zhao Yicang nodded: "Just leave these to me." ”

"Yes, I'll trouble the fourth uncle next." Zhao Yicang took over the work, Zhao Yanhuan simply let go and handed everything over to Zhao Yicang.

Employing people without suspicion does not need to be suspected, a capable gentleman mainly has the wisdom of knowing people, which is basic, but it is also very important to use people without doubt.

Of course, Zhao Yanhuan will not completely give up, after the arsenal is built, she still has to take a look, after all, how to build a coke oven and how to build weapons She has to give some guidance.

The arsenal was completed, and then Zhao Yanhuan began to build the school again, the teachers are all ready-made, and the outstanding students who graduated from the Qipai Village School can be teachers.

The school is full of children, Zhao Yanhuan gives land, gives high-yield seeds, only collects 30% tax, and rents good farm tools and cattle to the people, everyone's life is unprecedentedly better.

So as soon as Zhao Yanhuan said that they should let their children go to school, everyone was happy to send their children to school, if it was in the past, they would definitely not send their children to school.

It's not that they don't know the benefits of studying, it's that life is too hard, even if it's a child, it's a laborer, and it can work.

Besides, after going to school, the children not only can't work and eat for nothing, but also have to give money to the school, they can't eat enough, where can the money be given to the school.

Now that life is better, and Zhao Yanhuan's school is not constrained at all, the children only need to bring their own three meals, and even the pen, ink, paper, and inkstone for reading, Zhao Yanhuan has covered it, and the people have no burden.

In addition to the children who are focused on training in the school, Zhao Yanhuan also asked people to go to the fields to teach adults literacy, and reading is a very sacred thing in this era.

In particular, it is Zhao Yanhuan, a benefactor, who makes them literate, so even if they don't like learning very much, they don't resist literacy, and they are working hard to learn literacy in the spare time.

When Zhao Yanhuan asked them to learn literacy, she didn't set any high requirements for them, what she advertised was to learn simple common words.

Go out to see a road sign, look at a store sign, read a deed and you won't be deceived, learn simple arithmetic, and don't be deliberately cheated on money when you buy things.
