China's northwest is sparsely populated and has plenty of sunshine.

Xinjiang cotton in the 21st world is quite famous in the whole country, Li Yuanjia also deliberately bought a quilt from Xinjiang online, in addition to the merchants cutting corners in length, the winter can not cover the feet and make people indignant, it is indeed very comfortable to cover, and it is also very warm.

If you really take the Western Regions......

Is it possible to build a cotton planting base over there?

Although he doesn't know much about governance, Li Yuanjia understands a truth, that is, interests are the language of the whole world - if cotton can really become popular in China in advance, it is not impossible!

The more I thought about it, the more I felt that there was such a possibility, and Li Yuanjia's mood instantly became completely excited.

The promotion and use of cotton in the Central Plains is indeed a very difficult process, especially before the Ming Dynasty, when the ruling class had more luxurious materials such as silk and silk cotton, or fur fur to keep warm, and the demand for cotton was naturally not urgent. As for ordinary people, farming is to feed their stomachs, who would want to use precious land to grow cotton?

If it weren't for Zhu Yuanzhang's forcible promotion of cotton later, I don't know when this thing would become popular.

But now, Li Yuanjia has this thought!

So in his excitement, he immediately called the people outside the door in: "Chunyan, you immediately order to go down and prepare all the cotton in the house!" ”

"Huh? All? ”

After listening to his words, Chunyan was stunned.

"Yes, all the cotton!"

Nodding, Li Yuanjia said lightly: "If you can weave cotton cloth, weave it into cotton cloth as soon as possible, if you can't...... Well, let's make a quilt! ”

Thinking of the requirements of the "field hospital", Li Yuanjia was also quite helpless.

At the very least, he hopes that the field hospital under Huang Ren's management will have a relatively clean environment and can provide a comfortable place for the wounded and sick to recover...... The future has proven that hygiene, nutrition and comfort are indispensable for the rehabilitation of trauma patients.

Of course, the future conditions cannot be replicated in the thirteenth year of Zhenguan, but Li Yuanjia still hopes to be as good as possible.

It's just that there are so many things that need to be prepared to achieve such a goal.

Huang Ren: Needless to say, the scalpels and stitches they need to use, including a large amount of clean dressings and alcohol, are also the most basic necessary materials, and Li Yuanjia has already given the housekeeper an order that must be completed as soon as possible.

In particular, there is not much stock of spirits, and after Bahari has transported a large number of them, now Han Lucheng and their task is very heavy. Because according to Li Yuanjia's requirements, at least 300 jars must be brewed within three months, that is, at least one jar per month!

If it weren't for the fact that the brewing workshop outside the city had been completed and could be put into use, Han Lucheng would never dare to agree to this order.

In addition to these things, there are many other things, which were also written in a book little by little in Li Yuanjia's careful planning, and gave him a headache.

There are at least twenty cauldrons for daily use!

Li Yuanjia asked the blacksmiths to step up to build a cauldron that could allow people to go in and take a bath, of course, not only for cooking for the injured and sick, but also for a little too big and a little useless. After all, iron weapons are valuable these days, and many soldiers can't even guarantee the use of iron in their hands, let alone for cooking.

The cauldron in the wounded barracks, of course, is for disinfection.

After all, there are too many things to disinfect, not to mention anything else, the cotton cloth used to bandage the wounds of the wounded soldiers can't be used once and thrown away, right? Not to mention this era, even in the future period of the War of Resistance Against Japan, there is no such extravagant practice!

How many people do you need to disinfect these things every day? How many cauldrons do you use?

There are also knives, needles and threads that doctors use every day, as well as gloves, masks and other things that they wear every day, which also need to be disinfected every day to ensure safety, and twenty cauldrons may not be enough.

Anyway, whether it is boiled or steamed, as long as it can be sterilized at high temperatures, it must use a large iron pot and a special steaming drawer. Otherwise, with the traditional kind of crockpot or the like, the thermal conductivity is poor, and the efficiency is not slow, so that people are dying?

So the more big iron pots this thing, the more the better.

However......

An iron pot will cost at least dozens of catties of iron, and twenty mouthfuls is thousands of catties!

Although this is Chang'an, although Li Yuanjia's identity is King Han, it is not said that thousands of catties of iron can be bought, let alone that he wants more!

With an iron pot, naturally more coke is needed.

If you want to be efficient, logging and burning is the next choice...... Although charcoal fire is also very good, but that thing has been there for a long time, and there are countless trees that plague every year, Li Yuanjia has long looked unpleasant. In contrast, although the manufacturing cost of coke is much higher than that of charcoal because of the poor technology, Li Yuanjia, who knows the future development trend, certainly does not mind spending more money to promote it.

When the army goes on the march, is there a better opportunity for propaganda than at this time?

And it doesn't cost anything!

Although Li Yuanjia didn't expect coke to become popular all of a sudden, after all, the current production technology is still a bit difficult, and the cost is too high, which is not very realistic. But wouldn't it be nice to let more people know about this kind of thing in advance and arouse their interest and curiosity......

At this moment, Li Yuanjia didn't know how many thoughts flashed in his mind.

It's just that Chunyan didn't think about it so much, she just nodded and said, "Yes, king, I will order it immediately...... King, I'll give you another pot of water, this tea is almost gone! ”

"Tea ......"

Suddenly stopped his steps walking around, and when he heard Chunyan's words, Li Yuanjia's eyes suddenly lit up: "By the way, there are also tea!" Chunyan told Han Lucheng to take out all the tea leaves in the warehouse...... Well, leave some of the king's drink, and everyone else will be ready! ”

If it weren't for hearing the words of spring smoke, Li Yuanjia would have almost forgotten about tea.

The Great Army Marching West?

Just right, bring a few thousand catties of tea on the road!

Don't like to drink?

Never mind!

Anyway, as long as Li Yuanjia uses the mouths of Huang Ren and Ma Yuan, he will let the soldiers of the Tang Dynasty know a fact, that is, drinking some tea in the winter, chewing some tea leaves and swallowing them into the stomach, can make your stool smooth and have fewer sores in your mouth, so are you willing to drink, willing to drink, or willing to drink?

So if you think about it, the benefits of participating in a war are really enough!

And after being reminded by Chunyan, Li Yuanjia's mind seemed to come alive all of a sudden: "By the way, there are also Arabic numerals and abacus, you can also take the opportunity to show off!" When the time comes, send someone over with a few abacus, and sometimes it will be difficult to say that it can make people's eyes shine......"
