Iron in this era was controlled, and its value was comparable to gold, and Jiang blacksmiths had to go to the yamen to register and make records, which was equivalent to obtaining a business license, and they also needed to be guaranteed by someone with authority.

It is also necessary to take a certain amount of assets to the yamen as collateral, so that you can start your iron career and go to the yamen to buy pig iron or pieces of iron.

Pieces of iron are relatively soft, and after buying them, they have to go through thousands of tempers before they can be forged into finished tools, but it is the cheapest.

Pig iron is the Yamen Foundry Division with molten iron casting shape, the blacksmith takes it back and then reprocesses it, it can be made into a finished iron, of course, the price of pig iron is very expensive.

However, most of the folk blacksmiths do not have furnaces with good exhaust ventilation, and most of them can only buy expensive pig iron, because they do not have the skills and tools to forge the iron.

But the Jiang family is different, they have had an adventure, they have to build a good furnace, you can use pieces of iron to forge farm tools, etc., greatly reduce the cost, over the years, but make some money.

Otherwise, Jiang Fengshou, a blacksmith child, would not have the money to send him to a private school to study.

However, the Jiang family sent Jiang Fengshou to study not to get ahead in the examination, but the Jiang family's furnace has been used for many years, and it has reached the verge of collapse, and the ironware produced is getting worse and worse.

That's why I want to send my child to study, there is a lot of wisdom in books, maybe I can find a glimmer of life in it?

Don't look at the craftsman is a ninth-rate trade, as long as you have excellent skills, it is a job with fast money, you can support your family, and you can live a prosperous life.

In the end, what Jiang Blacksmith didn't expect was that the furnace didn't use his son at all, so Jiang Changan repaired it casually, and her method also came from the book, indicating that his initial thinking was right.

Reading makes one wise.

Anyway, his son can't be counted on, and now Jiang Chang'an is closer than his son in the eyes of Jiang Blacksmith, just like his reborn parents, who must be provided.

Fortunately, Jiang Changan is a measured person and never greedy, otherwise Jiang Blacksmith would have to lose his fortune.

"It's all the Jiang family, uncle, you're welcome, let's continue to make accessories for threshing machines." Of course, the drawings were prepared by Jiang Changan a long time ago.

It is quite convenient to do, it is as smooth as a production line, Jiang Blacksmith has a lot of iron storage, and Jiang Changan simply made eight accessories.

Now Jiang Blacksmith can also understand the drawings, because Jiang Changan's drawings are too easy to recognize, and if you can't understand the dimensions and remarks in those structural drawings, you can also ask Jiang Fengshou.

"These are all simple, I can do it myself, Chang'an, if you have other things to do, just go, and I will be able to send you the accessories in the evening."

The Jiang family is building a house, and Jiang Changan needs to deal with a lot of things, and the threshing machine also needs to have a combination of wooden accessories, so Jiang Changan has not started construction until now.

"Okay, I'll go back first, hard work Uncle Tie." It is not difficult to build and cast iron fittings, but it is difficult to design and assemble, so the matter is handed over to the old blacksmith for many years, and Jiang Changan is still very relieved.

Even if you make a mistake, the iron can be recycled.

Jiang Changan and Li Shushen came out of Jiang's house, and they met many villagers on the way, all talking about the old Jiang family.

said that who was crippled, who was disfigured, the most serious Jiang patriarch fell directly, his mouth was crooked and drooling, and his words were not clear.

Jiang Changan sighed, she really didn't mean it, it just so happened that this old man's illness and her grandfather's were so coincidental, stroke, who would have thought of it?

"What's the matter, soft-hearted or guilty?" Jiang Changan's methods can be said to be neat and thunderous, but he is still too soft-hearted.

In the era when human life was like a mustard, she couldn't bear to be a killer, she always thought that there were no casualties in her family, but did she know that if it weren't for her ability to turn the tide, the Jiang family would have been shattered and the family would have been ruined.

Whether it is Zhang San or the Jiang family, which one is not forcing the Jiang family to die, and never showing mercy to the Jiang family, listen to what the men of the Jiang family were talking about last night?

Not to mention the secret recipe of robbing others, but also destroying other people's assets, mutilating the male host, and robbing the hostess of other people's houses to go back and humiliate them.

Is this something that one person can do? This kind of evil people, if there are fewer people in the world, there can be a lot of peace.

Jiang Changan, she felt that she was underestimated, "Do you think I look like a kind person or stupid Bai Tian?" "Please call her the ruthless and invincible royal sister, thank you.

Jiang Changan felt that he was just a little right-hearted, and his kindness could not be reached.

"Not really." often calls her a little monster, but in fact, her eyes are particularly pure, how can she be a treacherous person, I was afraid that she would harm the Jiang family.

Now it seems that it is he who has the heart of a villain and spends the belly of a gentleman, "You are simply so." ”

When Jiang Changan was proud, Li Shushen said this again, and almost didn't choke Jiang Changan.

How could Li Shushen feel that he was stupid and sweet? Is the silly white sweet with fangs? Or did he have some misunderstanding about Silly Bai Tian?

"Hmph, I'm actually letting you, otherwise casually playing the characteristics of white flowers or green tea will definitely make you scared crazy."

Sample, kneeling down to you, Jiang Changan's appearance of not forgiving you is also interesting.

Li Shu covered his mouth and coughed lightly, and hid his smile, the little monster became more and more naturally active, I don't know if she found out herself, maybe she really regarded herself as a child.

"I've always bowed down to you, your manufacturing ability is too strong, can you also make iron and carpenter in your girl's house?

It's just ironwork, but carpentry is complicated, right? "Throughout the ages, are there any girls who know how to carpenter? Anyway, it's right not to be famous.

"Carpentry is actually a mortise and tenon craft, I have obtained a professional certificate before, these technical things, there are professional schools to teach, anyone can learn.

Carpentry is very interesting, adhere to its rules and rules to measure, a very ordinary wood, can be carved ingenious; On the land of nature, build a magical workmanship.

Since ancient times, inventions and creations have rubbed countless sparks of wisdom, which is the ingenuity of craftsmen, inherited for thousands of years, and the achievement of human civilization and development.

In fact, it is not much complicated, the building is made of wood, bricks and tiles as the main building materials, and is built by the main components such as columns, beams, and purlins, and the nodes between each component coincide with mortise and tenon joints to form an elastic framework.

The mortise and tenon joint is an extremely ingenious invention, which makes the traditional wooden structure bear a large load, and allows a certain deformation to be generated, and the seismic response of the structure is reduced by deformation through deformation under seismic load."

When it comes to professional knowledge, Jiang Changan can keep talking, and Li Shushen also listens quite seriously.

Until I saw Jiang Changan's face lightly, the serious little monster seemed to be glowing, which was particularly beautiful, and people couldn't help but be in a trance for a while.

"Little monster, you are actually really Lu Ban's disciple, right? The essence of his skills has been well inherited. ”

Where is there a school to study, not everyone has her wisdom, and some people are born to eat this bowl of rice, such Jiang Changan is really good-looking.

"Lu Ban is the ancestor of the carpenter, you can say so.

I've said so much, aren't you interested in carpentry? Whether you want to learn or not, when you learn the advanced level, you can build a mecha, a flying wooden bird, and a running wooden horse, all of which are possible. ”

Of course, in fact, Jiang Changan will do this, she hopes that a smart person like Li Shushen will join in, and she will have a helper for everything in the future, how good.

"No, what do I want, isn't there still you?"

Jiang Changan, can I not give it?!
