So Fan Jingjing went home and prepared to welcome her new partner.

However, back in the Fan family manor, a somewhat strange man suddenly came to the door.

Although it was a little unfamiliar, Fan Jingjing knew that this person had been living in the Fan family's manor for about a month.

Now that spring has passed, summer is hot, and everyone is tested by the heat.

In the past, they never considered the problem of wearing too many clothes, because usually the clothes covered the body were very little, and the tattered clothes could only be sewn and repaired, and the fabric could be less than that.

The whole family only has one piece of clothing to wear, and this dress must also be worn out during the day to show others, not a joke, and even the fabric they get is still a whim of the imperial court, come as a reward, and I have not been hacked by corrupt officials.

Sometimes, in order not to lose face, I have to go out in the middle of the night to work in the store, and I can imagine how difficult it is to work outside in the dark night.

You have to know that street lights don't exist.

Now the people of the Fan family manor have another kind of trouble.

In the Tang Dynasty, people are not able to wear cool clothes, and they are particularly bitter for the people in the Fan family's manor, because there are too many women in the manor, and Fan Jingjing's rules are too many, requiring them to be civilized people, and they are not allowed to play shirtless.

At this time, they can't wait for some snow to come under the ice and snow next to them, but when it's really icy and snowy, they can't wait to see the sun, because they can't get it, so they want it very much.

In fact, it is not just the people in the Fan family manor, all the people in the Tang have the same idea, that is, Fan Jingjing came to the Tang, although it is only the climate in early summer, because of the relationship between the Xiaoice River period and gradually comes, it is not really particularly hot, but compared with hiding in the air-conditioning room every day to blow the air conditioner, it is really much hotter, not to mention that she is pregnant with a child in her stomach, but she can't heat the child in her belly, she is especially looking forward to the appearance of the air conditioner.

Problem: Fan Jingjing crossed over too late, it was almost spring, the ice and snow had melted, and he was too poor at that time to dig a cellar to store ice.

Sun Erlang also followed, he knew that Fan Jingjing had a problem, that is, he couldn't remember the name, and being able to remember the names of several people around him was already very remarkable.

Sun Erlang felt very proud, he was one of the few names Fan Jingjing remembered.

"Wu Xinhui and a few people who like to use their brains to study, so Mrs. Fan took a little time to explain the principles of some good things to these people who love to use their brains."

Sun Erlang first introduced the person who made what Fan Jingjing wanted, Fan Jingjing was just trying at that time, and he would spend a little time recommending it to Sun Erlang every half a month.

Although she knows the scientific principles, Fan Jingjing really has no hands-on ability, don't look at her to do carpentry, but she knows some chemical principles, but it is still far from being able to do it by hand.

When they first began to explain these life sciences, these people didn't even know how to read and write, but they just liked to tinker with some things that could help their lives, and some of them still had some help in their lives, but because they didn't have the ability to read and write, the invented things were often used in a limited range, not to mention applying for patents. They are happy, not necessarily because of money, but because of the affirmation of his ability.

And this group of people also made Sun Erlang independent, allowing them to spend more time tinkering with various things.

However, they found that people still can't get out of life, out of life, and the things they drum up are often out of life, which is not very helpful to them at this time.

The best inventions are used to solve life's problems, which will continue to inspire them and can cause practical help.

Of course, Fan Jingjing also gave them some new tasks, such as the production of printing ink, but this kind of thing that is out of life is still more difficult for them, because there is no such thing in their daily life, so the progress of research and development is relatively slow.

The weather was hot, and they began to be interested in what Fan Jingjing said could make ice and reuse.

According to the principle that Fan Jingjing said, Fan Jingjing's principle was too general, so they failed several times in the experiment, but they were always able to learn new lessons from the failure.

Wu Xinhui is the leader of this group.

He led the first research on ice-making.

Fan Jingjing didn't ask anything, nodded to Wu Xinghui with a smile, and then asked, "How did you do it?" ”

"In fact, the process is very simple, just do a little more experiments, and then make it. Put the water in the jar, take a larger container, put water in the container, then put the jar in the container, and keep adding saltpeter to the container, and the water in the jar will freeze. ”

The Fan family manor has the presence of saltpeter, which is a necessary item for making matches.

But saltpeter didn't flow out of the workshop, so how did they get it?

According to Fan Jingjing's memory, saltpeter had not yet been invented in the Tang Dynasty, and it seems that it was only discovered in the late Tang Dynasty when mining was made.

"How did you find saltpeter?"

"In fact, this principle was discovered by the people in the workshop, and our main research is actually how to make saltpeter."

Wu Xinhui was a little hesitant when he said it, and he didn't know if it violated Fan Jingjing's confidentiality clause, but this person didn't tell him how to make matches in the workshop.

If he is punished, he will not feel very good.

Fan Jingjing sighed softly, there is still no way to prevent it, other things that have not been explained have been revealed, fortunately, the people who this person comes into contact with in his daily life are still the people of the Fan family manor, and the people of Datang are used to living in a small place, and the transportation is generally inconvenient, which also makes them bound to the land.

Spending two hours a day and running to Chang'an is too much time for them.

Their lives are very busy every day, and there are so many things that need to be dealt with, and if they can't handle them, it will have a very big impact.

Although she felt that this incident had done her more good than bad, she still had to remind the staff in the workshop.

After all, matches are one of the big projects to make money now, and it is not the time to spread out, not to mention that the development of saltpeter to the future of gunpowder will be fatal to the Tang Dynasty if it is preferentially mastered by the Turks or foreigners.

There are a lot of foreigners near Chang'an who come to this place to do business, and the heads of foreigners who come to do business.

It is much more flexible than the people of Chang'an, most of the people near Chang'an are officials or farmers, and the heads of these two kinds of people tend to be more immutable, these foreigners who like to take risks and make difficulties are different, and these foreigners find something that is helpful to their group or business, and they will find a way to get it back.

The accumulation of various cultural stimuli will eventually lead to the great development of culture, and then Datang will become backward.

What I am most afraid of is that Fan Jingjing knows that saltpeter can be developed into gunpowder, and gunpowder is a big killer no matter what era, because gunpowder can also continue to be researched and developed until the emergence of hydrogen bombs.

In Datang, it is a weapon that can change the pattern of the world, and it will soon be able to achieve world harmony, but the management ability of the times has not yet been able to manage the whole world, and even if the world is united, it will soon collapse and continue to develop in war.

And in the war, many people will disappear in the war, and the rapid war may not only not increase the population of the human race, but will also be destroyed quickly, and finally degenerate into a way to support the development of culture.

The food problem has not yet been solved!

Fan Jingjing didn't know if it was a good thing that she developed saltpeter hundreds of years earlier.

However, Fan Jingjing thought that she had begun to master the concept of chemistry by the Pope and the Princess, and with the concept of chemistry, compared to their slow research later, it could be hundreds of years earlier, this technology should be able to be controlled by the Tang Dynasty, and it would not be controlled by other countries, even if they could bring saltpeter back, it would take a long time to study all the things after that, after all, their number is smaller, and their food is not necessarily sufficient, and in the case of insufficient food, it is even more difficult to develop the peasant population.

And these research matters must be focused on the same thing, and there must be a large number of people who have left the countryside.

In the future, the scientific foundation will develop rapidly, that is, many people can leave agriculture and do further research in their own positions.

If you already know the principle, it will be much easier to prove it, or to grasp it, than to discover it.

"Wu Xinhui, I'll give you some new tasks, but you can also find some people who can cook delicious things to try, maybe they have bigger ideas."

"Delicious? Isn't ice just a way to cool down the room and make it more comfortable? ”

"That's one of the features, but there's a more direct way, you can make these ice products into all kinds of drinks and desserts, and if you can knock it down and turn it into fine shredded snow wool ice.

Fruit juice will be delicious!

I want you to develop these ice products, and then the people in our manor can find some people to sell them, but this secret must be preserved and not let anyone know.

So you've got to make people who can keep the ice longer, so that they can drag the ice out and sell it, because the shelf life is equal to how much they can sell, and you know that the saltpeter can be reused after it's dried, right? ”

"We haven't studied them yet, but luckily we haven't thrown them out because I'm afraid they'll be polluting, so I'm going to dry them and start researching them, and we're going to look at the insulated objects further."

Fortunately, the eyes are shining, so the value of these ice cubes will be even higher, and if there are trustworthy people who can make ice elsewhere, such ice products can spread out.

This is because it is not difficult to make ice cubes, and the raw materials used to make ice cubes can be reused. But the interests behind it are really too great.

"I'll help you pick one, but you have to get the insulation equipment out so that we can think about how to develop delicious ice products in the future, and you can't forget it."

As soon as Fan Jingjing's brain rolled, she found a new way of wealth for the Fan family manor, and these new ways of wealth were on the fruits, so she would find a way out for the fruits of the Fan family manor, otherwise so many fruits picked in the mountains were also brought out by condensate, and if they could be made into ingredients for ice mowing, they would be able to obtain greater benefits.

However, if you want to make it affordable for the average person, or if you want to eat it all, you have to spend a little bit of brains to make the ice and juice taste together.

However, in terms of food, the people's imagination is very rich and great, and Fan Jingjing feels that the imagination of Ji and Fan's manor should be able to come up with delicious ice products that are not available in later generations.

Thinking of this, Fan Jingjing's saliva was about to flow down, she hadn't eaten ice for a long time, especially the deliciousness of ice cream, which often made her unforgettable.

Although Fan Jingjing drew a lot of beautiful patterns in her mind, each of which could leave her with a lot of saliva, but at this time, Wu Xinhui's mind was a mess, and they couldn't understand how to break the ice into many pieces and turn it into soft as snow.

Fan Jingjing suddenly, high-fived and said: "I'll draw a picture for you to study to see how you can become sharper, and then tell Jiang Blacksmith that they can make a machine that can thin the ice for you, by the way, temporarily set the secrecy level to Class A." ”

"So you can spread it when you start using it?"

"It can't be helped, it has to give people a sense of superiority, and once the machine is seen by others, it is easy to imitate, because as long as you know the shape it represents, and with a little bit of creativity, you can make it.

Our secrecy has to be put on the ice, and only if we can do what others can't, can we sell for a good price and have a steady stream of customers. ”

Although it is not easy for Datang to confirm the patent right, it is not so easy to imitate.

There are many things that lack a key point, and if you get it through, it's easy to do, but if you don't, it takes a little time to crack it.

What's more, there are no cameras or phones, so you can transmit information without being noticed.

Fan Jingjing has a water balloon, which can review the minds of the workshop members, as long as there are people with strange thoughts in important parts, or there are some changes in their minds.

Fan Jingjing had to find a way to return these people, in fact, through the water polo to supervise Fan Jingjing, she still found that people's hearts are really very easy to change, fortunately, this change is a good change for the Fan family manor.
