When Jiang Changan went home, it was early, Old Man Jiang was still tidying up the wood in the backyard, Jiang Lao Er and Mrs. Jiang were helping, and Yao was making clothes in the house.

Jiang Lao Er bought a lot of fabrics and came back, but the first one had to be made for the two old people in the family, which was a necessary filial piety.

Yao knows everyone's size, and it is fast to make, or the kind with a few embroideries on the neckline and cuffs, which looks much more high-end than ordinary clothes.

Old man Jiang was about to go back to the kitchen to drink water, and when he raised his eyes, he saw Jiang Chang'an who was about to enter the door, and he was happy on his face, "Chang'an!" Fig.

He stopped halfway through his words, because, Jiang Changan was followed by a lot of people, this? Isn't it not good to talk about drawings in front of so many people?

Carpentry drawings are equal to the kung fu cheats of martial arts, the secret recipe of the chef, when the old man Jiang made cattle and horses for many years, he learned some fur.

So if Jiang Changan drew a drawing, he was quite reluctant to let outsiders see it.

"The picture is ready, you can take a look." Jiang Changan didn't understand the bitterness in Old Man Jiang's heart, so he took out the drawings with a big face, spread them out directly, and showed them to Old Man Jiang.

Old man Jiang's eyes lit up, he glanced at it, and quickly put away the drawings, "Why did you bring someone back again?" The tone is not resentful, the granddaughter is good at everything, but she is too lacking in heart.

"My classmates are interested in the cart, so I'll take them for a tour."

What's the matter, it's not enough to show the drawings, you still have to teach others to do it? Old man Jiang wanted to cry, "How can our exclusive technology be open to outsiders?"

These little rabbits are also ignorant, how can they come to steal the teacher?

At this moment, even the youngest people feel a little embarrassed, they are not here to steal the teacher, I don't know if the old man believes it or not.

"It's okay, they're just rare, even if they learn it, it's fine, the woodworking market is not saturated, and the construction of Da Song also needs them."

In such a backward dynasty, some of them are to be developed and built, and this is just carpentry technology, not weapon forging, and it does not endanger the security of the country and the people, so there is nothing to cover.

As soon as Jiang Changan's words fell, her classmates immediately respected her.

Starting from pottery, whether it is making salt, ice, cars or drawing paper, Jiang Changan has never wanted to hide from them, it turns out that he regards them as the pillars of the country, and looks forward to building the future of Dasong with them?

This vision and bearing are really exactly the same as Song Fuzi.

The mood of the students suddenly became heroic, as if they suddenly had a different but the same goal, to study hard and build Dasong.

They also finally understood why Master Song not only taught them the knowledge in books, but also taught them martial arts, farming, and all useful skills.

Combining work and rest, you can really learn more things.

Shen Shikang became suddenly open as if he had been opened up to the second vein of Ren Du, so he bent down to Jiang Changan and saluted, waiting for the salute of the teacher.

Jiang Changan's growth is too fast, and her achievements are already prohibitive, and many people finally peeked at the reason in her, so what reason is there not to work hard, all of them have ordinary family backgrounds, and they have no willful capital at all.

"Chang'an Dayi, we will definitely study hard and live up to your intentions."

Jiang Changan smiled, "Okay." "If you can endure that hardship, then learn.

Old man Jiang has nothing to say, the child has children's thoughts, let them go.

"You take the drawings and go to the backyard to see the materials first, and I'll let my mother cook some ice soup."

The classmates are happy, all look forward to it, drink ice soup in summer, that is the treatment of large families, now they will use saltpeter to make ice, and there is more fun in summer, which is very good.

A few classmates pushed Sang and followed the old man Jiang to the backyard of Jiang's house.

"Ling'er, what soup are you going to make?" She heard her right, right? Ice soup? But they don't have an ice cellar, where does the ice come from? Yao heard the movement and walked out of the room.

"Sour plum ice soup, mother, ice can be made of saltpeter, it is this stone, broken into powder and added to water to absorb heat, the water will become cold and ice.

It can be made in a basin with a bucket of water in the middle and a bucket of chilled sour plum soup.

It just so happens that grandma has dried a lot of bayberry this year, so you can borrow some to cook it. "There are two large bayberry trees in the backyard of Jiang's house, and the fruit that can't be eaten and sold every year is unsold, so Mrs. Jiang takes it to dry.

Occasionally, guests can add some sugar to make a sweet and sour soup, which is still very good, of course, it is better if you add ice.

"This white stone turned out to be saltpeter, huh?" I thought it was rare, but yesterday Jiang Changan carried a lot of it back and put it in the yard.

In the past, her stepmother spent a lot of money to buy it back and hide it as a treasure, but in fact, tsk, every mountain in their countryside is saltpeter.

Yao suddenly felt that he was rich.

"That's right, I'll make ice now, mother, you can cook soup, remember to put more sugar." Ice soup is just sweet and sour to be delicious, and there are few girls who don't like it.

"Okay." Yao went to cook the soup.

Jiang Changan took a few pieces of saltpeter and crushed them into powder, then poured them into a large basin, poured a lot of water into them, and let them stand.

Then I went to cut a few bamboos to make a tube, and cut a stick in the middle to prepare, well, the ice soup to drink, but, it can also be made into a popsicle, that is the child's favorite.

There was mint in the backyard, and there were some glutinous rice flour at home, ready-made materials, Jiang Changan moved quickly.

When there was no one by the saltpeter basin, the Jiang family in the third room secretly breathed a sigh of relief, "Do you think you can really make ice?" "Isn't that developed?

Yesterday, the Jiang family was still thinking about what Jiang Changan was doing with an ominous white stone on his back and putting it at home, but could it be used to make ice?

Ice is old and valuable in the summer, and they can also make ice to sell on the street, isn't it very profitable? Paper suddenly couldn't sit still.

"If that's really saltpeter, it must be able to make ice." As the book says, Jiang Laosan knows, but he doesn't know saltpeter.

"Shall we take a look? The operation steps are simple, if you really want to make ice, we can go to the street to sell ice guides, and we don't have to work in the fields in the future, and we can make money easily. "Jiang wants to be his own boss in his dreams.

"W-Isn't it? Isn't this voyeurism, the second one will kill us, right? "It was when the spring breeze in the second room was proud, and Jiang Laosan was instantly cowardly.

"You are stupid, the little fool didn't hide it at all, and when he burned the pottery, the kid from the landlord's house watched the whole process; Now the carpentry craft is for those classmates to watch; Saltpeter was carried back by many classmates yesterday, and she had already told others about the formula.

We're just going to see it now, what kind of voyeurism is it?

If you want me to say, the little fool is still the little fool, and now he has a food inside and out, how generous and friendly he is to outsiders, and he will be stingy with us uncles and aunts. ”

If the little fool is willing to help them as uncles and uncles, do they need to be thieves and peeps? Sure enough, no one can rely on anyone, only on their own, so some technical secrets have to be grasped in their own hands.

It's too difficult to carpenter and burn pottery, but it's easy to make ice and soup.

"Don't say it, let her hear it, what if you don't even want to see the child in the third room? You look at Jiarong, you know that if you run to please the little fool, you will have meat to eat. ”

made Jiang Laosan envious.
