The Prestigious Family’s Young lady and the Farmer

Yang Tiezhu held his breath, and Lin Qingwan also held his breath. After a while, the water in the jug was completely frozen.

Yang Tiezhu couldn't believe it, he looked at his daughter-in-law, Lin Qingwan smiled happily at him, and then he touched the ice in the jug with his hand.

Really icy? !

He was so excited that he couldn't speak, "Daughter-in-law, what's going on? How could the water turn into ice?"

Can Lin Qingwan tell him that because the dissolution of saltpeter in the water will cause the water to cool down rapidly, and then cause it to freeze? Can she tell him that she also read the novel? Certainly not, and he didn't understand it.

So she could only make up a pretense, "I don't understand this either. That's how the big family I stayed in made ice."

After Yang Tiezhu heard it, he nodded excitedly, then turned around and wanted to inform others.

Lin Qingwan grabbed him and told him not to worry, and brought the water in the small pot to the stove to cook.

In order to fear that Yang Tiezhu would not be able to operate, she also followed.

Although Yang Tiezhu didn't understand why his daughter-in-law did this, he thought she must have her own reasons, so he honestly lit the fire and started boiling water. There wasn't much water in the small pot, so after a while on high heat, it was gān, and then a layer of powdery crystals appeared at the bottom of the pot.

The appearance of the crystals is the same as the saltpeter that Xia Dacheng gave her, but these must be finely crushed.

Only then did Lin Qingwan feel relieved, and asked him to scrape off the crystals, then filled the small basin with water, replaced it with a water can, filled it with water, and then put the scraped crystals back into the small basin.

Saltpeter can be reused, that is, it is necessary to distill the water in it, and then scrape off the crystals and use it again. Of course, it can't be used endlessly, and it will lose some every time, but it is very small.

It was not until the second ice-making success that Lin Qingwan was completely relieved and asked Yang Tiezhu to notify Xia Dacheng to come over.

As soon as Xia Dacheng returned to the room and lay down, he was called up by Yang Tiezhu. But looking at his cousin's excited look, he knew there must be something wrong.

On the way, Yang Tiezhu whispered to Xia Dacheng about his daughter-in-law making ice, and now Xia Dacheng started running.

When they came to Yang Tiezhu's house, Lin Qingwan was still sitting at the table waiting for them. On the table was the small water basin and the water jug ​​in the water basin.

Xia Dacheng saw the ice inside at a glance, and touched it with his hands excitedly.

Really ice! OMG!

Xia Dacheng stabilized his excitement and sat down at the table.

"Is my brother and sister looking for me to talk about ice?" His tone was a little unstable.

Lin Qingwan nodded, her eyes were still a little dazed, she had been thinking about the problem before they came in, and she still didn't come back to her senses at this time.

She tapped her forehead with her fingertips and asked, "Where did Brother Dacheng buy these saltpeter? Is it easy to buy? Is it expensive?"

When smart people talk together, it saves trouble, and Xia Dacheng immediately understands what Lin Qingwan means.

He thought for a while in his mind, and then slowly answered: "I bought these ground creams in a large pharmacy in the county, not a medical center, but the kind of place that supplies herbs to major medical centers. Thanks to a friend of mine, I was able to buy this stuff there, because no one else sells it. It's not expensive. It cost about 22 taels in total. As for whether it's good to buy, I also asked the shopkeeper in the pharmacy. , It is said that this thing is not used much, so the stock is very small, and the stock I got back is almost all the stock in their pharmacy. So-"

Therefore, it is not advisable to make money by making ice. Even if Xia Dacheng didn't finish his words, Lin Qingwan understood what he meant.

She sighed slightly and said, "It's okay, after this lesson, let's dig an ice cellar to store ice in winter for the next year. This method can only be used for emergencies."

Xia Dacheng nodded, he also had this idea.

but--

"Brother and sister, can this ice support us to store preserved meats?" When he said this, Xia Dacheng's heart was pounding.

How could he forget that it takes a lot of ice to store preserved meat, what can such a small crock do?

Lin Qingwan glanced at the water jug ​​in embarrassment and nodded.

"Should be reluctant to be able to, I'll think about it again."

After Xia Dacheng was relieved, he went back again.

Lin Qingwan said that she was tired and was going to lie down for a while, and then went to Carpenter Cui to make a few wooden boxes on behalf of Yang Tiezhu. It didn't need to look good, as long as it was strong and sealed with a lid, let him make it as soon as possible.

After Yang Tiezhu helped his daughter-in-law to lie down, he went out to find Carpenter Cui.

...

Carpenter Cui was also quick, and after listening to Yang Tiezhu's words, he rushed out two wooden boxes the next day. Not even painted, just a boxy box with a lid and a buckle on it.

Yang Tiezhu took it back and showed it to Lin Qingwan, who was very satisfied.

She took out a few more small quilts she made for the baby, and the small quilts were so small that they just put a layer in them. She simply put two more cups in, and then put the bowls of ice she made in the morning, including the bowls and ice, into the box. After putting it in, I was worried, and two small blankets were covered on it.

Fortunately, she was not busy at the time, and she always felt that there was not enough to do for the child. She made 5 or 6 pieces of blankets, which came in handy now.

Lin Qingwan closed the box and left it alone. Seeing Yang Tiezhu's curious appearance, she also j

Iāo don't move this on his behalf. She will take another look at noon.

Although Yang Tiezhu was curious, he also listened to his wife's words, and there was no such thing as secretly watching.

After lunch, Lin Qingwan opened the box and took a look.

The box is powerful, the quilt is also powerful, and the ice inside is even more powerful, and there is no trace of melting.

She put the bag away and covered the box again. Yang Tiezhu, who was watching from the side, was stunned, but he also knew that this was about the preservation of fresh preserved meat, so he didn't come over curiously to reveal it for a while.

In the afternoon, Lin Qingwan came to take a look again. Only at this time did the ice show signs of melting. A thin layer of water had melted on the bowl, but there was still a lot of ice.

When she came to see it again at night, there was still no sign of the ice in the box melting significantly, so she really put her heart down.

Yang Tiezhu was also beside him.

At noon, he was just guessing, but after thinking for a long time, he could not come to a conclusion. It was only at this time that he understood what his daughter-in-law meant.

"Daughter-in-law, how did you know that putting it in the box and covering it with a quilt can delay the melting of the ice?" Yang Tiezhu was so excited at the moment that he thought all this was amazing. Shouldn't it be the hotter it gets, the faster it melts?

Lin Qingwan rolled her eyes in her heart, can she tell him that when she was a child, people who saw people selling popsicles used wooden boxes with quilts to keep them warm? Later, with the foam box, this old-fashioned one was replaced. But later, the refrigerator and freezer were greatly promoted and became a cheap item, and then even the foam box was eliminated.

Insulation can not only keep high temperature, but also keep low temperature. There is no foam box here, but the principle is still the same, right? Nothing more than sealing and insulation.

She couldn't tell her man the truth, she could only tell him that the big family she stayed in had done this before. Then he pretended to be impatient and urged him to let Carpenter Cui drive the wooden box out, and then let the women in the family who knew how to sew quickly get some cotton fabrics and make some small quilts out.

Her doll's quilt was just taken out for testing, but she had no intention of contributing. After all, these fabrics are all good materials, and it is good to use some poor fabrics for the small quilt used to keep warm.

While scratching his head, Yang Tiezhu thought to himself that the family that Wanwan stayed at was so powerful and could do everything, he kept busy at his feet.

Several women in the family rushed out a bunch of small quilts one afternoon and one night. In the middle, Yang Tiezhu also went to the town to buy a pile of coarse cloth and cotton, so I won't describe them one by one here.

Yang Tiezhu was busy outside, and ran back to make ice cubes. Lin Qingwan explained to him all the steps in the middle, so he got it right.

Now the tools are simple, and the basin for water at home is too small, so he can only make a few bowls of ice cubes at a time.

This time, without being reminded by Lin Qingwan, he was almost enlightened. He decided to wait for Carpenter Cui to make a few larger wooden pots. Just a few more ice bowls. But thinking of this, he felt that it was not good to use a bowl of frozen ice...

After thinking about it, he went to get the "practice board" that Lin Qingwan made for him, and found a piece of charcoal to draw on it.

Lin Qingwan slept in the room for a while, and found out why her man hadn't come back to sleep. Seeing the light in the main room, she got up and walked over. From a distance, I could see Yang Tiezhu's very serious pattern, holding a board and writing and drawing.

She took a closer look curiously, only to find that Yang Tiezhu had a few patterns on the board. One is a big boxy frame framed by a small boxy frame, and the other is a big circle framed by a small one. His strokes were very unfamiliar, and the shapes he drew were crooked, but Lin Qingwan could still see the approximate shapes he drew.

Lin Qingwan stood beside him for a while before Yang Tiezhu reacted.

"Hey, daughter-in-law, why haven't you slept, are you standing here?" Yang Tiezhu put down the board and charcoal in his hand, and seeing that his hands were dark, he quickly picked up the cloth next to him and wiped it.

"I don't think you came back to sleep, just wondering what are you doing? What are you drawing?" Lin Qingwan raised her chin at the board.

Yang Tiezhu scratched his head blushing and smiled, "I think our frozen pot and bowl are inconvenient, so I want to find Carpenter Cui to make a few more. But, if you don't tell others how he looks, how will he know? What do you do?"

Lin Qingwan nodded with a smile in her eyes.

Good boy, know how to invent tools.

"Then go ahead and think about it, I'm going to bed first, don't delay it too late." After speaking, he turned around and went back to the house.

Man, don't hit him too hard, even though she already has a rough image of the object in her mind. However, since he tried so hard to think for himself, let him think about it. She can't be a daughter-in-law and run ahead in everything. Isn't that a blow to a man's self-esteem? ! It's better to move your brain more, and you will be more flexible after you move more.
