Shen Shu has been settling down on the island for half a month, and at present, she is quite happy with her neighbors, if there is anything she is not satisfied with, it is in terms of eating.

Liuli Island is divided according to the temperature zone of the previous life, it should be considered to be in the tropical range, the temperature remains high all year round, the changes in the four seasons are not obvious, and the cold and heat are also relatively speaking. Fortunately, the forest coverage area on the island is very considerable, if you only count the area within Shen Shu's sight, it has reached more than 95% coverage, even if the sun is scorching, as long as you stay in the woods, you basically don't feel the heat.

At the beginning, I didn't think about it so thoroughly, so that Shen Shu enjoyed the feeling of a sauna in the house at noon on a sunny day, and the taste was sour. After that, she didn't say a word, and invited the previous craftsman back, and built a summer hut on the edge of the woods, for safety reasons, the house was surrounded by thick/large wooden stakes, leaving only a gap for children's arms to pass through, a movable gate, made of stakes as thick/large as the guardrail, but a simple pulley device was added under the door, otherwise it would be difficult for her and Cui Yi to push the door.

Having said that, because the weather is too hot and there is no refrigerator, fresh food is difficult to preserve, and meals are a problem overnight. Although she can hire someone to bring fresh vegetables from the shore every day, and Shen Shu is not short of these money, it is really too troublesome, and she still feels that she needs to have an ice cellar.

Because he didn't know much about the technological development of the Southern Dynasties, Shen Shu deliberately went to the shore to learn about it, and then found that this era was still in the stage of 'hiding ice' by storing ice in winter for summer use, and due to the hot climate in the coastal area, the so-called winter was only a relatively cold summer with a relatively cold climate, and it could not reach the freezing conditions at all, and the people living here basically did not have ice cellars.

Shen Shu felt a little square. In the 21st century, a feudal dynasty that pushed back thousands of years, it was possible to artificially make ice, using saltpeter accidentally mined during the manufacture of fire/medicine to absorb heat and cool the water, so that the water could reach a freezing temperature.

Unexpectedly, this place was still in the most primitive stage, which made Shen Shu can't help but wonder if there is such a thing as saltpeter for sale on the market. She inquired with little hope, and sure enough, she didn't.

I instantly felt so tired.

Accompanying Shen Shu was Yue Donghai, and when she saw her disappointed expression when she came back, he asked, "What's wrong with Miss Shen?"

Shen Shu's idea of wanting to build an ice cellar was just something she knew in her heart and didn't say it, and after going ashore to inquire, she went to inquire by herself, and Yue Donghai was just waiting for her at the ferry, so she didn't know why she was disappointed.

"I was a bit disappointed that I couldn't find what I was looking for. Shen Shu didn't hide it, and said it directly.

Yue Donghai asked again, "What is Miss Shen looking for?"

Since he asked, Shen Shu replied casually, first talking about saltpeter, seeing that Yue Donghai was at a loss, thinking of the factor of cultural differences, he changed to describe the characteristics of saltpeter. She didn't really say it with any hope, but simply wanted to explain it clearly.

However, she didn't expect Yue Donghai to tell her, "I seem to have seen this kind of stone on the island that Miss Shen said, but I'm not sure if it's it." ”

This news is a big surprise for Shen Shu, although it has not yet been confirmed that it is the saltpeter she is looking for, but it is better to have hope than no hope.

So she urged Yue Donghai to return to Liuli Island. However, due to the late arrival time, and then a long delay on the shore, when they returned to Liuli Island, the sun had almost completely disappeared from the sea level.

In this era, when the night comes, it is not suitable to go out for activities, not to mention that on the way back, he told her that he found that the stone suspected of saltpeter was in the depths of the woods, and it was about an hour or so away from Shen Shu's summer cottage.

I can only wait until the next day to find it.

So the next morning, Shen Shu got up early in the morning, got up when the sun was just rising above the sea level and the sky was breaking, and by the way, Cui Yijing also woke up, and after packing up, he took him to find a nearby neighbor, bothering the other party to help take care of him for a while, and when those children woke up, they would come to play with him.

After living on the island for a period of time and having a regular playmate, Cui Yijing will not follow Shen Shu at any time, but she can't leave for too long, and she should come back around the evening at most.

After Shen Shu settled Cui Yijing, Yue Donghai had been waiting at the summer cottage for a while, and when he saw Shen Shu coming, he handed her a small porcelain bottle, "There are more mosquitoes in the forest, wipe this on your body." ”

Shen Shu took it and said thank you, opened it and applied some on the bare/exposed skin, and soon there was an indescribable smell filling the nasal cavity, which was a little uncomfortable, but it was still within the scope of bearing.

When they were ready, the two of them went into the woods and walked along a path that was completely unrecognizable.

The woods in the outermost part of Liuli Island are just the most ordinary kind, although the vegetation is flourishing, there is still sunlight shining overhead, not the kind of tropical rainforest that covers the sky and the sun, and people will not be afraid to walk in it.

From the periphery of the woods to the destination, it took more than a month to walk, and although she had been prepared, Shen Shu was still well entertained by the mosquitoes in the forest. But fortunately, this qiē is worth it, and what Yue Donghai found is really the saltpeter she needs.

Saltpeter was found deep in a cave where a chill could be felt in the cave, although the climate on the island was very hot. When she saw the real thing, Shen Shu still felt a little hard to believe that there was such a coincidence, she needed saltpeter, and there was no trace of it anywhere else, but it was found on this island. She took a moment to briefly inspect the surroundings and found that there was quite a lot of saltpeter, at least a miniature deposit.

For Shen Shu, this is the sublimation from an unexpected surprise to a huge surprise.

After resting in place for a while, she and Yue Donghai each took some saltpeter and set off back to the village.

Because he overestimated his body, he had only walked less than a fifth of the way back, and Shen Shu began to gasp. Later, Yue Donghai silently moved all the saltpeter on her body to herself, reducing the burden for her, but even so, the return journey still took nearly half an hour longer than when it came.

This is the first time that Shen Shu clearly realizes how wasted her physical fitness is, she thinks that she is not in the mansion anyway, she doesn't have to worry about the suspicion of the people around her to do something, it's time to start exercising.

However, it is imperative to get the ice cellar out first. Shen Shu hesitated between the main house and the summer cottage, then decided to dig a cellar on the side of the summer cottage, and then invited the previous craftsmen to supervise and guide the work for the third time.

There is great strength in numbers, and it didn't take long for the cellar to be built. During this period, Shen Shu and Yue Donghai went to the saltpeter mine twice, and many kiss marks left by mosquitoes could already be seen on the naked/exposed skin, Yue Donghai said that he didn't agree with her to continue to follow, he called a few big children, each carrying a big basket, back and forth several times a day, and the saltpeter brought back was piled up, and the amount was already considerable.

Shen Shu planned to calculate their wages, but Yue Donghai waved his hand and said no, as long as he provided two meals a day, and if he could, he would give a few children a few small snacks. However, Shen Shu ignored his opinion this time, "You don't want it to be your own business, and whether they want it to be their own or not, you can't mention them to call the shots." ”

Yue Donghai was stunned when he heard this, and then admitted his mistake, "It was my mistake." ”

His neat attitude made Shen Shu a little embarrassed. Fortunately, this matter passed quickly, and when the cellar was ready to be put into use, Yue Donghai finally couldn't help but ask Shen Shu, "What is Miss Shen doing?"

In fact, not only him, but other people on the island were also quite curious, because Shen Shu had only been on the island for about a month, and he had already built three times. Yes, for the Yue family, building a cellar can be called a big construction.

Shen Shu was a little surprised when she heard this, "Alas, didn't I say it before?"

The people present were not only Yue Donghai, but also a few children, and everyone shook their heads in unison.

"Well, it's my fault, I'm so busy that I forgot about it. Although he said that, Shen Shu still decided to sell a small pass, "You should all be curious, it just so happens that my classroom has been built for almost a month, and it is time to play a role, you go back and tell the other children, gather in the classroom tomorrow morning, I will give you the first lesson, and tell you why when the time comes." Of course, there are no restrictions on children, and adults can also come if they wish. ”

The words had already been released, so she began to get busy, preparing all kinds of materials and props needed for teaching, and finally found that she could only make up teaching props for twenty people. There is no way, when the time comes, I can only do it in groups first, and then ask someone to go to the shore to buy it and come back to make up enough numbers.

Early the next morning, almost all the children on the island got up early in the morning, and after simply cleaning up, they came to Shen Shujian's school building.

Liulidao Primary School - This is the sign hanging at the front entrance of the school building, most people are illiterate, and the few who are literate can't understand what it means.

In about a moment, the people were almost all here, dozens of children plus a dozen adults, fortunately, Shen Shu built the school building wide and the ventilation design was relatively good, otherwise it would be time to enjoy the sour feeling of sauna again.

Shen Shu randomly divided the children into three groups, and then asked the children in the first group to come forward first, two large wooden long tables were put together, twenty children stood around the table, and a group of props were placed in front of each person.

Shen Shu stood on the podium and clapped her hands, "Everyone calm down first, listen to me say a few words," paused, and after quieting down, he continued, "I guess some people will be curious about what I built this school building for, let's put it simply, this is equivalent to a academy on the shore, a place to teach people to read and write, but I am used to calling it a school." Starting from today, Liulidao Primary School officially opens, I will arrange a class schedule to come out, and take a certain amount of time to come here every day, if you are interested, you can come and listen. Now, let's start today's first lesson, Chemistry and Food. ”

Shen Shu felt that she had already said it very simply, but most of the people present were still confused and couldn't figure it out, and they all looked at her with curious eyes. However, Shen Shu does not force this, education is never something that can be achieved overnight, but a gradual process.

After finishing speaking, she began to instruct the children in the first group to place the props on the table first, correct them one by one, and then start to distribute the materials, in addition to saltpeter, a piece of candy for each. When she was sending sugar, she clearly felt that the eyes around her suddenly became hot, and she was inexplicably under some pressure.

Shen Shu continued to instruct the children in the first group to carry out practical operations under pressure, constantly putting saltpeter into the water, saltpeter dissolving and absorbing a lot of heat, and after repeating it several times, Shen Shu asked them to put sugar into the water, and then put the small wooden sticks that went down into it. Several children were a little reluctant, but seeing that others had voted, they could only endure the pain.

After a few more moments, the water in the small jar in the middle had begun to freeze.

"Wow!"

Surprises followed.

Children who live on islands all year round have never seen ice at all, just as people living near the equator have never seen snow, and it is very surprising for them to see the original liquid water solidify into a transparent solid little by little.

It wasn't until the water in the jar was completely frozen that Shen Shu asked them to stop putting saltpeter, and then took one of the people's jars, held the small wooden stick and moved it a few times, and then took out the whole ice cube. Transparent ice cubes appeared in front of everyone's eyes, and a piece of maltose was frozen in the middle, which was the Southern Dynasty version of a simple popsicle.

"Taste it. Shen Shu handed the popsicle to the child.

The latter hesitated a little, but he didn't resist the temptation, so he brought it to his lips and stretched out his tongue to lick it.

"What does it smell like?"

"Is it delicious?"

"How does it feel?"

"Can you really eat it?"

One question after another came out of the mouths of those around him. After a long while, the first child to taste the crab said, "Cool, sweet, delicious!"

After having the first person who dared to try, soon a few children did not need Shen Shu's guidance, imitated her previous behavior and took out the popsicles to taste, and the evaluations were unanimously praised.

For a moment, all eyes were focused on Shen Shu, and the children in the other two groups were asking when it would be their turn.

For a moment, Shen Shu felt that she felt the spirit of the 21st century foodie in these children, and they were undoubtedly curious about the cause of this phenomenon, but they preferred the crystallization of this chemical reaction - popsicles.

In this regard, Shen Shu felt that her mood was a little complicated.

But no matter what, this means that the first class she taught in Liulidao in the Southern Dynasty was undoubtedly very successful.
