Chapter 154 Hand Crank Loom

……

After each taught the brother and sister a trick.

Wu Wen exchanged a few more words with Cheng Yaojin.

Then he said goodbye and left.

Return to Dingxiang City.

Wu Wen directly called Ashina Simo over.

"I asked you to buy wool. How much have you collected so far?" Wu Wen asked.

Ashina Simo did not give a specific number, but just answered "a lot".

"Take me to see it." Wu Wen said.

So, under the leadership of Ashina Simo, Wu Wen came to a pasture outside Dingxiang City.

There are several tents set up in this pasture, and a large herd of cattle and sheep are grazing around them.

Ashina Simo brought Wu Wen to the back of the tent.

There were two piles of wool piled up here like small hills.

Wu Wen walked forward and looked at the unprocessed wool.

Not only were the wools extremely dirty, they also emitted a foul odor and were crawling with flies and other small insects.

Cheng Chumo, who came with him, asked in confusion, "My Lord, what do you want these wools for?"

"Useless?" Wu Wen said with a smile, "It just looks useless now. Once I process it, the wool will be useful."

The main reason why these wools are dirty is the grease on them.

To clean them, you need to remove the grease.

The best way to remove grease is to soak and wash it in lime water.

After the cleaned wool is dried.

We need to use the tools designed by Wu Wen to deal with them.

This is a round drum with two layers, inner and outer.

There are many sharp protrusions on the inner wall of the outer layer, and also on the rollers of the inner layer.

Put dry wool in and turn the drum, the messy wool will be combed and stick to the inner wall and the drum like a layer of cloth.

Then you can take them out and tear them into long strips, which can be twisted into wool yarn.

Turning wool into yarn is only the first step.

After that, the wool yarn needs to be woven into woolen cloth.

Wu Wen also designed a hand-cranked weaving loom.

Its structure is very simple: the frame is the main body, supporting and fixing various components.

The weaving area contains the needle bed and knitting needles, which are responsible for weaving the wire into a pattern.

The handle wheel provides power to drive the knitting machine to work.

The transmission mechanism transmits power to the knitting needles, ensuring that they move according to the trajectory.

The wire guide system guides the wire into the braiding area, adjusting the tension and position.

This machine.

Only one person is needed to weave quickly and conveniently by hand-cranking.

Even if someone has never done it before, once they get the hang of it, they can weave two rolls of woolen cloth in a day.

For the imitation manufacturers of this era, Wu Wen's hand-cranked knitting machine is like a dimensionality reduction attack.

Let Ashina Simo send someone to deal with the wool problem.

Afterwards, Wu Wen, under the leadership of Ashina Simo, came to the Sun and Moon Mountain, 40 miles north of Dingxiang City.

The reason for this name is that the mountain is divided into two sections for some unknown reason, one of which is round like the sun and the other like a crescent moon, hence the name Sun and Moon Mountain.

Wu Wen came here because there was a salt mine in Riyue Mountain.

Mineral salt is poisonous. The Turkic people who graze on the grasslands collect mineral salt and feed it to cattle, sheep, horses and other livestock to replenish the salt in their bodies. Apart from this, no one mines this salt mine.

When Wu Wen learned the news, he thought about mining the salt mine and refining the toxic mineral salt into refined salt that can be eaten by humans.

In the north, salt is a very precious thing.

The reason why Wu Wen dared to say that he would open up trade and was able to attract merchants was because he had control over precious things like salt.

Just entered Sun and Moon Mountain.

Walking in the gap between two mountains.

Wu Wen could see the mineral salt exposed everywhere.

There is no need to mine it, just send people to pull it out.

Then, Wu Wen stopped going deeper and told Ashina Simo: "Collect more of these mineral salts and bring them back to Yanmen Pass."

Ashina Simo was a little puzzled as to why Wu Wen wanted to transport so much poisonous mineral salt, but he did not ask and just had people start moving it.

A team of people, carrying thousands of kilograms of mineral salt, went to Yanmen Pass.

Before this, Wu Wen had also thought about making salt in Dingxiang City.

But then I also considered that I couldn't always do this kind of work myself. If I let others do it, the technology would definitely be leaked.

So, he thought of handing over the technology to Cheng Yaojin.

Cheng Yaojin himself was a salt merchant and was very familiar with this business.

As for whether he would embezzle Wu Wen’s technology.

To be honest, except for some remote mountainous areas and other places with special geographical locations, the Tang Dynasty actually had no shortage of salt.

The reason why salt is so precious and scarce is entirely because of monopoly.

Some things may seem precious to ordinary people, but to some people, they are just ordinary things.

Yanmen Pass.

Wu Wen found Cheng Yaojin with thousands of kilograms of mineral salt.

In front of the mansion gate, Cheng Yaojin looked at the things he brought and asked in confusion: "Why did you bring these poisonous salts?"

"Come into the house and talk."

After entering the house.

Wu Wen took out a piece of paper and pushed it to Cheng Yaojin, saying, "This is a technology that can refine poisonous salt into edible refined salt."

Hearing this, Cheng Yaojin's eyes lit up and he immediately wanted to open it to have a look, but then he withdrew his hand and said with a smile: "Such a precious thing, what do you want to give it to me?"

"Of course I would like you to help me refine these poisonous salts into refined salt." Wu Wen replied.

Cheng Yaojin smiled and said, "You want me to be a laborer! What benefits can you give me?"

Wu Wen pointed at the secret recipe and said, "This is the benefit."

Cheng Yaojin thought for a moment and said, "You should present this skill to the court."

Wu Wen raised his eyebrows and replied, "Does the court need this thing of mine?"

Cheng Yaojin smiled and said, "The court is not short of it, but Your Majesty is short of it.

Nowadays, more than 50% of the salt in the world is controlled by the aristocratic families. If your thing falls into the hands of Your Majesty, Your Majesty will not have to compromise with the aristocratic families on the issue of salt. "

Wu Wen continued to push the secret recipe and said, "Duke Su, you can hand it over to His Majesty, but you have to take over this matter of mine."

Cheng Yaojin smiled and put away the secret recipe, saying, "This is natural.

Now I understand why you have the confidence to open up the trade. It turns out that you have this good thing in your hands."

There are two main sources of salt on the grassland: one is lake salt, and the other is salt circulated from the Tang Dynasty.

Both of these places are far away, so even though there is no shortage of salt, its price remains high.

If salt could be mined and refined in Dingxiang City, many merchants would be attracted by the low price.
