I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Ajiamu stared at Liu Tan with wide eyes and stammered, "Your Highness...Your Highness, are you serious?"

Liu Tan also felt that he seemed a little too excited just now, coughed lightly and said: "It should be possible, but I just have an idea, don't rush to tell Ah Xuan when you go back, if it doesn't work, it will just make him happy for nothing."

Ajiamu immediately said: "What Your Highness wants to do will definitely be done!"

Liu Tan couldn't help laughing: "You have confidence in me, that's fine, you're tired from running all the way, go and rest."

Ajiamu knew that His Highness the King of the North must have had some thoughts, so he didn't continue to disturb Liu Tan.

In fact, the first thing Liu Tan did after he left was to write a memorandum, explaining the importance of stealing the house, and explaining the importance of beating Che Shiguo by the way.

After finishing writing, he couldn't help but sigh with emotion. The country that attacked him when sending off his relatives before was left with Che Shi country, but because of the special status of Che Shi country, he couldn't move lightly.

Originally, he thought that he would not be able to take revenge in a short period of time. As long as the Huns were not destroyed, or the Huns were not completely suppressed, Che Shi Kingdom would have to be kept there.

Unexpectedly, he had the opportunity so quickly.

So what if Lu Xuan finishes fighting the Xiongnu, or when the Xiongnu finds out that Che Shi's country has changed hands?By that time, he has already occupied the country of Cheshi, and if the Huns dare to come, he will dare to fight.

But at that time, if the Xiongnu wanted to come over, they had to cross Zhuoxie Mountain, or pass Lu Xuan's pass first.

After Liu Tan finished writing the memorandum, he sent someone to send it to Chang'an in a hurry, and then began to study wool.

In fact, the use of wool by humans can be traced back to the Stone Age, but over the years, wool has been used more to make blankets and felts. In terms of textiles, wool has different lengths and high impurities, which leads to processing. It is difficult, so the price is also high, so even Central Asia, which is good at making blanket felt, has not been able to make wool into soft and light clothing.

If you want to turn wool into clothing, you must first turn wool into something that can be spun on a large scale, and you must first allow wool to enter the wool top manufacturing process.

Liu Tan ran to the warehouse to take a look at the wool, but was smoked out before entering.

Miao Rui looked at Liu Tan, covered his nose and frowned, and said cautiously: "Your Highness, these wools smell really strong, so ordinary palace people don't want to come here. What are you here to see?"

Liu Tan ran to a place where the smell was not strong and took a deep breath, and instantly lost his appetite.

If you want to lose weight, you can put the house next to this warehouse, the effect is absolutely good.

It's a pity that Liu Tan didn't have this idea. He played with Liu Che for four months before and he managed to gain some weight. Before leaving, Liu Che patted him on the shoulder and said, "Keep working hard and gain some weight, it's still too thin .”

In order not to let Liu Che dislike him for being skinny the next time he came over, he decided not to go near this warehouse any more.

Of course, if you don't get close or not, you still have to do what you should let the people below do.

He turned his head and said to Miao Rui: "Don't worry about anything else, let's find a warehouse and have someone cut and dust the wool before we talk about it."

The wool can't be spun without cleaning it. Before studying the next step, he'd better let these people clean the wool first.

There are too many impurities in the raw wool, there must be grease, there are sand, dung eggs, dust, grass thorns, all kinds of things, oh, there may be some bugs in it, such as fleas .

Fortunately, this warehouse is outside the palace, otherwise Liu Tan would definitely have to have the entire palace cleaned up for him, nothing else, he would never be able to bear fleas!

As for the process of cutting wool and soil, there is actually no need for Liu to talk about it. After all, even if making felt or blankets, the wool must be cleaned first.

The first thing to do is to loosen the wool little by little to form fluffy pieces, and then remove all the impurities inside to ensure that there is nothing but wool and the oil on it.

After the wool is opened, the wool is washed.

These days, even in the Western Region countries, which have a relatively high utilization rate of wool, most of the washing of wool is done with clean water and some plants. The cleaning effect is not good, so the wool after washing is still rough and hard.

Liu Tan speculated that later generations should use chemical detergents for cleaning wool. Unfortunately, Liu Tan was not sure about the ingredients of those detergents, so he could only let people try washing with soap first.

I have to say that even simple washing with soap can make the wool cleaner, especially the cleaning of grease is much stronger than before.

After washing, the wool is dried in the sun, and then combed.

Carding is also divided into carding and combing. Carding is to simply comb the wool once, in order to comb the knots and hair balls inside, and prepare for the next step of combing.

Now the traditional wool felt and wool blanket making techniques can basically be used here.

However, the wool produced by such methods cannot be spun at all, so the next step Liu Tan only knows is to comb it again to straighten the wool.

And then...even Liu Tan got stuck.

Those things he made before, at any rate, he may have seen them or touched them in the process of playing with models.

But he really has never been in touch with the wool making process, and all he has seen before are finished products.

After combing, Liu Tan tried to get people to weave directly with a spinning wheel, because at this step, the wool becomes particularly fluffy and fine, but the yarn spun in this way still needs to be tied.

At this point, the finished product has almost been produced, and the rest is to make these wool threads into clothes through production.

When the first garment made of wool was made, Miao Rui and Bi Gao were a little surprised.

Most of the wool products they saw in the past can still see the original shape of wool, but the woolen clothes are different. They look clean and fine, and they feel very soft.

Miao Rui and Bi Gao thought about the raw wool they had seen before, and then looked at this dress, saying that they could not be connected together.

After the two of them sighed, they looked up and found Liu Tan sitting there frowning.

They couldn't help asking: "Your Highness? Is there something wrong?"

Liu Tan was stunned for a moment: "Huh? No, it's just a little different from what I thought."

The cost is too different from what he thought, and this cost is only a little cheaper than using cloth. In fact, it cannot be treated as armament at all.

In fact, in addition to the high consumption of soap, the rest is labor costs.

Perhaps it is also because there are fewer people in the northern border country, so manpower is more expensive, but even if this is the case, it is impossible to supply large quantities.

Because the spinning speed can't reach it.

The norm here in the northern border country is that women are used as men, and men are used as livestock, so when farming, the whole family is involved in the battle. How can there be women who can sit quietly and weave?

As for the previous steps, Liu Tan thinks about it, but it can be transferred to other places. He immediately wrote a letter to Ji Fei, asking him to find a way to buy wool in Guan City. It needs to be purchased in large quantities, but not all at once. It is best not to Let the Huns notice.

But there are also requirements for wool. Those that must be cleaned, and those with sand and various impurities in them are not allowed. Try to clean the wool that you get. This step can at least save a lot of manpower.

Think about the use of wool on the grasslands, that is, to make wool felt, but no one re-makes wool felt every day, so for them, wool is basically a relatively useless thing, so Liu Tan should be able to buy wool at a very low price in the early stage of information asymmetry.

As for the requirement to clean the wool, it is also normal. After all, the wool is collected according to the weight, and the impurities are also counted by weight. They don't want to have no problems.

Anyway, they are the only ones buying wool now, and there are more sellers than buyers. I believe the Huns will help them clean it up.

After you don’t have to worry about this aspect, the next step to improve is the problem that weaving requires a lot of manpower.

Because of his lack of understanding of this aspect, he temporarily transferred Xiao Cheng and said, "Go and help me find out what common people use for weaving."

Xiao Cheng was silent for a while before he said: "Your Highness, you want to know what utensils the common people use for weaving?"

Liu Tan nodded: "Yes."

Xiao Cheng said with a smile: "You don't need to ask this, I know that the spindle is generally used now."

Liu Tan was stunned for a moment: "Spindle? Isn't there a spinning wheel?"

Xiao Cheng said: "The spinning wheel... requires wood, which ordinary people can't afford."

Oh, yes, the situation in the northern border country is special. Wood is extremely precious, so wooden things are also more expensive.

Liu Tan said helplessly: "Forget it, let someone get me a spinning wheel."

Only by improving production efficiency can we fundamentally solve the problem of manpower shortage.

Xiao Cheng choked for a moment, looked at Liu Tan, and was very puzzled, not knowing what his Highness wanted the spinning wheel for.

If it was Huo Guang who spoke, Xiao Cheng might ask directly. Although Huo Xiang usually looks strict, he actually has a good temper.

Well, it is said that his temper was honed by His Royal Highness the King of the North.

But Xiao Cheng thinks it's because Huo Xiang has a good temper. After all, Huo Xiang is really strict with himself and lenient with others. Of course, the premise is that you are also an honest gentleman. When facing villains or criminals...then they will see it How powerful Huo Xiang is.

Xiao Cheng left with a full stomach full of questions. He was very fast and sent the spinning wheel to the northern palace on the same day.

It's just that Huo Guang and others came in with the spinning wheel.

Thus, in the northern palace, Liu Tan watched the spinning wheel and other people watched Liu Tan.
