"Of course the Western Regions produce cotton~"

"And from the Western Regions to the west, this large area is all cotton-producing, and the cotton produced is not only high-yielding, but also very slender cotton lint, and the best quality cotton."

Liu Jin nodded solemnly and said.

"But the Western Regions are under the control of the Warats, and now that the Warats have advanced eastward and are annexing the former Tatar tribes, how can we get the Western Regions."

At this time, Xu Guangzuo said helplessly.

This matter is also a headache for Emperor Hongzhi now, the northern steppe began to be unstable again, once Warat unified the northern steppe, maybe another Mongol Empire will rise, there will be a huge threat to the Ming Dynasty.

"Nothing is impossible~"

"Last year we were able to wipe out the army of the little Tatar prince, and we can also pack up the army of Warat, and drive the Warats further west."

Liu Jin smiled and said very confidently.

"And the second method I mentioned to find alternatives is actually related to the northern grasslands."

"Cotton can be used for spinning and weaving, and this wool can also be used for spinning and weaving, and compared to cotton, wool is warmer, and wool can be produced all year round, and the output is greater."

"Wool?"

When Zhang Mao, Zhu Fu, and Xu Guangzuo heard this, they were dumbfounded again.

"It's cashmere, right?"

Zhang Mao thought for a while and said.

"No, it's wool, wool is completely different from cashmere."

Liu Jin smiled and shook his head and said.

"Cashmere is the finest and softest wool on a sheep's body, and the yield is very small, and generally only a small amount of cashmere can be obtained from lambs."

"Wool is different, wool is produced in large quantities, and it is wool sheared from adult sheep, and after this wool is sheared, the sheep will grow hair again, and there will be a steady stream."

"But this wool is very dirty, and it smells of sheep, who would want this wool."

Zhu Fu thought about it and said, and when he said this, he looked disgusted.

The wool on the sheep, everyone knows, because it is mixed with oil, soil and many other things, it is very dirty, and there are small animals and the like in it, and more importantly, the smell of wool is too strong, even the grassland will not use wool to weave anything.

"Let's go, I'll take you to a place, and see if you can use this wool to weave~"

Liu Jin smiled and said very mysteriously.

Its practical wool to weave cloth, Liu Jin has been studying this technique for a long time.

The wool is very dirty, and the smell of sheep is also very strong, but it can be disposed of in a way.

Later generations made of wool clothes, towels, and so on were all good things.

"Mysterious and mysterious~"

Zhang Mao, Xu Guangzuo, and Zhu Fu were also curious, and followed Liu Jin out of Liu's Mansion to the southern suburbs outside the capital.

Here in the southern suburbs of the capital, Liu Jin specially made out a large piece of land and built a Tiangong Institute here for the study of various technologies.

Here in the Tiangong Academy, Liu Jin raised tens of thousands of blacksmiths, carpenters, clay craftsmen, and other people who relied on craftsmanship and technology to eat in this era.

Learn Arabic numerals, learn mathematics and some simple physics and chemistry, and then study a variety of techniques according to Liu Jin's requirements.

When recruiting, Liu Jin only recruited a small number of older people, and most of them were teenage dolls and apprentices.

These people are still young, they are capable of learning, and at the same time they are more imaginative, more malleable, and more creative when they study all kinds of things.

Artillery technology, flintlock muskets, explosives packs, new spinning machines, looms, and so on were all researched here, and of course, the most important technical guidance was provided by Liu Jin.

The whole Tiangong Academy is divided into three research directions, one is the physics research direction, and now the main research is the study of machinery and steel, the study of how to make more precise, faster and more efficient machines, the study of how to smelt better steel, how to forge steel quickly and so on.

One is the study of chemistry, mainly the study of explosives, the study of more powerful explosives, and the study of dyeing of cloth and so on.

The last one is the study of biology, mainly the study of medicine, because Liu Jin classifies medicine into the category of biology, where medicine is studied, how to cure diseases and save people, and Western medicine in later generations.

Tiangong Academy is one of the places that Liu Jin attaches the most importance to, and has invested a lot of silver here before and after, just to feed these tens of thousands of people, it will take millions of taels of silver every year, not to mention that all kinds of research and the like also require a lot of expenses.

But the role is still a little, to free Liu Jin from technical research, if you want to get some things, just give some information, and let the following people study it, basically they can be studied.

Liu Jin also often comes here to take a look, see if there are any new achievements, and then find ways to use these achievements to promote the development of capitalism. Let's go slightly

At this time, he brought Zhang Mao, Zhu Fu and Xu Guangzuo to the Institute of Chemistry, and the entire Institute of Chemistry was also divided into many areas, with different research contents.

"It stinks~"

"Liu Jin, what kind of place is this?"

Xu Guangzuo covered his nose, the whole person couldn't stand it, it was too smelly and the smell was too strong.

"This is where I specialize in researching how to turn wool into a raw material that can be used for weaving~"

Liu Jin smiled and introduced.

Only then did they observe it carefully, and they saw that the huge clearing was full of small mountains of wool, which at a glance knew that it had been purchased from the grassland.

It was very dirty, a lot of wool was clumped, and the white wool turned black and gray, giving off a bad smell and sheep's smell.

Looking further afield, there is a large pond with soaking wool in it, and some people are constantly washing the wool, washing the soil and the like from the wool.

Because the wool was so dirty, that the water in this pool was black, muddy, and very dirty.

Looking further away, there was a cauldron that seemed to be boiling something, and a thick stench came from here.

"Come, everyone come with me~"

Liu Jin looked at the disgusted looks of the three of them, smiled and said, "These wools are all wool that I asked people to buy from the grassland. ”

"No one wants this wool on the grassland, the price is very cheap, and a pound of salt can be exchanged for a full cart of wool~"

"Now you take a closer look at the wool, it's very dirty, the dirt, the fat on the sheep, and so on, and it has a very strong smell of sheep."

"To turn this wool into wool that can be used to weave cloth, it needs to go through several steps of processing."

"First of all, the first step is to clean~"

Liu Jin said as well as taking them to the cleaning area.

"Let's first clean the soil on the wool with water, so that the wool will be much cleaner~"

"Then remove some of the things on these wool bodies, such as plant seeds and the like, this cleaned wool, you can take a look, is it much better?"

Liu Jin picked up some clear and clean wool and said with a smile.

"It's really much cleaner, and it's whiter~"

Zhang Mao and the three of them looked at it carefully, and couldn't help nodding slightly.

"This cleaning is the process of removing grease, we can boil it in boiling water to remove some of the oil mixed in the wool, and we can also boil lice and other things in the wool to death."

Liu Jin took the three of them to the area where the wool was boiled, and the washed wool was thrown into boiling water to boil, and a large amount of grease and some other dirty things could be clearly seen.

"Let's see, after this boiled wool, its odor is much smaller, and it is not too greasy."

Liu Jin said with a smile while explaining.

Zhang Mao, Zhu Fu and Xu Guangzuo watched carefully, and listened carefully, and couldn't help but nod their heads.

"Next, these boiled wool will be soaked in a potion to remove all the fat and mutton smell on the wool~"

Soon, Liu Jin and the three of them came to the big pools, which were soaked with a lot of wool, and each pool had different chemicals in it.

Among them, there is a pool specially used to remove oil, which is specially used to make soap, and calcium fatty acids are added to it, which can completely remove the oil in the wool.

There are also pools that add bleaching chemicals that can restore the color of the wool to a snow-white, snow-white state; There are also pools that are specially designed to remove the smell of sheep's body, and the wool that has been soaked does not have any peculiar smell.

"Let's see, these wools are the wool that has been processed in the final form, do you think this kind of wool is worse than cotton?"

Coming to the last step of the process, Liu Jin smiled and picked up a ball of wool, which was very white, snow-white, snow-white, as soft as cotton, the key was that there was no peculiar smell, and he could no longer smell the slightest smell of sheep.

"Incredible~Incredible~"

"Is this still wool?"

"It's better than cashmere~"

Zhang Mao took the wool in his hand, his eyes widened, and he couldn't believe it, even if it was cashmere, it was somewhat sheep's smell, but the wool in front of him had no smell at all, and it was very snow-white.

"If that's the case, this wool can really be used for spinning and weaving~"

Xu Guangzuo's eyes widened, and he couldn't help but nod and say.
