It's the middle of November, and the bitter and fierce cold wind is mostly blocked by two high mountains, and after blowing in, it already looks weak and chilling.

Outside, when the sun rises, the body is warm, there is a charcoal fire in the house, and you can go to a hot spring every once in a while, and everyone's life is quite comfortable.

On this day, Yun Niang came back from washing clothes, and while drying clothes, she said to Abu: "When I was washing clothes today, I heard a few aunts chattering there, saying that when washing clothes, you can put some soda ash into it, and the effect of decontamination will be much better, and I will try it next time." ”

After listening to Yun Niang's words, Abu was taken aback, and hurriedly took Yun Niang's hand and looked at it: "Have you used it too?" ”

Yun Niang felt that his reaction was a little big, and said, "No, when they went, I was almost done." ”

Abu thought for a moment and said: "Soda ash is irritating and corrosive, it is harmful to the skin and eyes, and it cannot be used indiscriminately, I have to go and see." ”

After speaking, he hurriedly went out of the door, and as soon as he came out of the door, he poked his head out and came back: "You must not use it like this, I will find a way to try to make a better detergent." ”

After Yun Niang responded, Abu's head disappeared outside the door.

Speaking of which, the place to do laundry is not far from the hot spring baths.

Last time, Aunt Li gave Abu a suggestion, saying that the hot springs are good, but after everyone comes out of the bath, they have to put their hands in the cold water and scrub their clothes.

On this cold day, can you bring out a warm water for everyone to wash their clothes? It's not a good thing to do all the laundry in the bath.

After hearing this, Abu felt that it made sense, people, if you are not afraid of no way, you are afraid of no idea. Since there are conditions to enjoy, we must meet them!

So a large pond was stored nearby, and a hot spring water flowed through it, and after natural cooling, it was just used to wash clothes.

When I arrived at the laundry, I saw several women washing their clothes there. Maybe there was something funny to say, giggling from time to time.

When everyone saw Abu coming, they stopped their hands and greeted him. Abu also learned from them to crouch on the edge of the pool and reach out to test the temperature of the water.

Li Baotian's daughter-in-law next to her, Wei, saw it and quipped: "Why is there still Mr. Lao Abu, who came to wash clothes in person?" Didn't the little lady Yun Niang just finish washing, and she is about to go to the cave room, why don't you help you wash some clothes? ”

"Yes, isn't it after marriage, Mr. Abu has to do the laundry by himself, Yun Niang's little lady, looking delicate, I didn't expect to be so prestigious."

"Next time, we have to talk to Yun Niang, why do you treat our great benefactor like this? No more, there are so many of us here, young and beautiful girls, all eyes are staring, and then marry another one, specializing in laundry. ”

Everyone laughed. Therefore, when the women rise up, the men are beyond the reach of the dust. Especially women who get married, have children, and live for a long time, even more so, meat and vegetarian are not taboo.

Abu hurriedly said that everyone could see that he had taken nothing, what clothes had he washed? It's just for yourself.

Before, everyone had a kind of awe and love for Abu. But after a long period of contact, I found that Abu had a gentle temperament and was delicate, and everyone had a closer relationship with him. It's also a pleasure to joke with him and tease a handsome young man.

Abu consulted them on what to do with the dirt. Aunt Li said that you can soak the ashes of plants and trees in it, stir it well, it is the so-called gray water, put the dirty clothes in it and soak it, and directly beat it with a clothes pounding stick, and you can wash it clean. Because everyone wears coarse cloth clothes, the leather is solid and resistant to hammering, if it is the silk and satin of a large family, then they will take the bath beans used in the bath directly to wash the clothes, anyway, the family has a big business, and they don't care about those.

Abu asked how the bath beans were made, and Aunt Li had rich life experience, so she said that the dirty blood of the pig pancreas must be washed first, the fat removed, and ground into a paste, and then the bean flour was added, mixed evenly, and dried naturally, which can be used to make bath beans.

Although Abu had used bath beans before, he really hadn't studied how to make them. Now there are more cattle and sheep in the valley, and there are few households that feed the pigs, so he asked, how about using cattle and sheep pancreas?

Aunt Li laughed and said, that's okay, it won't be a big smell on your body at that time, be careful of Yun Niang's little lady, don't let you go to bed sir.

Abu is embarrassed, and his heart says that even if I don't use it, I haven't been to Yunniang's bed, okay? But this kind of talk cannot be explained to this kind of woman who can fight well, it is really getting darker and darker, and when the time comes, she will fall into the pit and will not be able to get up.

And Hou Wei said that the last time she washed clothes, she tried the soda ash made by Lao Li, and the washing effect was very good, but her hands were a little hot.

Then Abu explained to them that soda ash is irritating and corrosive, and should not be used directly. If you get into the eyes, it's more troublesome.

Abu is a doctor by profession, and when everyone saw that he was serious, they all agreed to keep it in their mouths and in their hearts.

Abu said that there is no need to worry, he will find a way to make a washing product that is convenient for everyone to use without hurting the skin.

Wei said with a smile that Mr. Abu still feels sorry for us, and has always cared for the personal life of the majority of women.

Abu fled in despair, and there was a burst of women's laughter behind him.

Abu went to Liu Yuanlu's residence, and when Liu Yuanlu saw Abu coming, he hurriedly greeted: "Third brother, come and see, see my little invention." ”

Now Liu Yuanlu is the only brother, and Abu doesn't see him, so he goes into the back room.

When Abu saw the object in Liu Yuanlu's hand, he was surprised, and took it with surprise, isn't this just a thermometer?

He didn't expect that without his participation, Liu Yuanlu would develop it by himself! Except that there is no scale, and the brown liquid column inside is thicker, the others are the same.

Abu couldn't help but give a thumbs up: "Second brother, did you do this?" ”

"Yes, the second brother is quite powerful." Liu Yuanlu was triumphant, "I've heard you talk about thermometers before, after Lao Li made glass last time, I wanted to see if I could make one." ”

"But how did you get this glass tube?" Abu felt very strange, such a thin glass tube, it was not easy for him to do it himself.

"This?! Didn't you mention to Lao Li last time that you can blow glass slurry through a metal pipe? I'll go to Bai Boda and ask him to help me get a fine tube. ”

"Lao Bai said that it was too long to be funny, and it was too hard to forge, so he finally helped me get a thin tube that was half a foot long, and I added a long wooden pipe in front, not to mention, the effect was not bad."

"It's amazing, my little brother admires it a lot!" Abu had to admire that the wisdom of the ancients was no worse than that of later generations. Why did I think about it before, why should I get a long metal pipe? Liu Yuanlu made a long wooden pipe, and lengthened it to solve the problem.

"Then Uncle Li Baotian, did Uncle Li also learn to blow glass?"

"Yes, he taught me this craft, and he told me that the process is similar to that of making porcelain bowls and pots before; It's just that one is made of mud and the other is made of molten glass slurry. ”

When Abu heard this, he was silent. It seems that once the door of knowledge is opened and people's horizons are broadened, everyone's invention and creativity will be stimulated, and the future development process is difficult to estimate.

There should be nothing wrong with the argument that there is a big explosion of knowledge and the acceleration of technological development.

In the end, at best, he is just a small butterfly with vibrating wings.

Next, Abu explained to Liu Yuanlu that if this thermometer is inserted into the ice, the height of the liquid column can be regarded as zero degrees; If you put it in boiling water, you can think of it as a temperature of 100 degrees.

With this measurement standard, it is possible to make a rough thermometer. Liu Yuanlu was very excited after hearing this, and immediately wanted to start the experiment.

Abu hurriedly grabbed him and said, "Second brother, don't worry, I'm here today, there are other things to discuss, the thermometer is easy to do, take your time in the future." ”

Liu Yuanlu stopped and asked Abu what else he wanted, and Abu said: "I want to make a washing product for washing clothes, and the second brother can take the lead in doing it." ”
