The shelter was busy in full swing, and Zhao Yunxiang put a large wooden pier in front of him, which was about to make a panel.

Of course, this is not a panel on a computer, but the kind used for noodles!

Because of the lack of tools, Lao Zhao is chopping with an axe, first cutting out a general model, and then leveling the section to be a panel.

More than ten minutes passed......

Zhao Yunxiang finally made a panel, and after Lao Zhao scratched it with a machete and dagger, he finally swept the end face and made a larger panel.

The specific shape is probably fist-shaped, because it is irregular, and the maximum diameter is 1.4 meters, which is used for improvisation anyway.

Han Qianluo and Lin Qingxuan are making lotus root powder, and the two of them are in full swing researching together.

"Teacher Han, you're listening to me!" Lin Qingxuan brought a rough stone, this stone is granite, the surface is neat and flat, Zhao Yunxiang usually uses this as a whetstone.

However, this girl found that this stone is very suitable for grinding lotus roots!

"You mean, use this stone to grind the lotus root into a pulp, and then filter it with my white shirt?" Han Qianluo listened to Lin Qingxuan's simple analysis and made a rough arrangement.

"Yes, so that we can eat lotus root noodles this afternoon!" Lin Qingxuan pointed to the sky and looked at the huge sun.

The rainy season on a desert island is terrible, and the heavy rain comes as soon as it is said without consulting you, and it lasts for a long time.

However, the dry season is even more deadly, as the huge sun releases heat, which will continuously transpire the water from the earth.

"Okay, let's come together!" Han Qianluo washed the lotus root, peeled it, and then began to grind, a large amount of lotus root pulp began to gather, Teacher Han took off the white shirt, changed it into a snakeskin vest, and then used the shirt as a filtering container.

Soon, a large amount of lotus root was ground into a pulp, and a clay pot contained a lot of white liquid, which was the juice of lotus root.

"The color is very strong...... Han Qianluo stretched out his finger and dipped it a lot, and found that the juice of these lotus roots was very viscous and needed to settle for a long time.

The clay pot is placed in the shed and let it settle slowly, and the final layer of sediment left behind is lotus root flour, which is basically the same thing as starch.

Han Qianluo hugged his knees, pouted, and stared at the lotus root powder slurry in the clay pot, his eyes raised slightly, "I have an idea!"

"Let's talk about it!" Lin Qingxuan blinked, indicating that he was willing to listen.

This girl likes Teacher Han very much, not because she likes it simply, but because she ......

"Don't we have a lot of potatoes, and we can make them into starch, or process them at high temperature to make vermicelli and so on. Han Qianluo suddenly became excited when he thought of the slippery taste of the powder.

After Zhao Yunxiang heard the pink skin, he showed a complicated expression.

I remember when I was a child, my grandmother next door often made flour skin at home, which seemed to be made of sweet potato powder, and she would make a lot of it, hang it on the shelf, and the whole patio was powder.

The noodles she made are used to make money to supplement the family, Zhao Yunxiang often goes to her house to eat noodles, and the old lady also likes children, and she will take a lot of them with her after eating at home.

It's just that the old lady's last life was not very good, and the money she earned was given to the children, and the children in the family would only come home on the day of the New Year.

"Pink Skin's words...... It's not difficult to do!" Zhao Yunxiang pondered for a moment, "However, we should dispose of those walnuts first. ”

Walnuts have been drying on the ground for a long time, and when it rains, they are put away and put in shelters, waiting for the sun to come out before taking them out to dry.

After a few days of high temperature exposure, several walnuts that were already moth-eaten actually cracked, and they cracked a big hole.

Lao Zhao, the tool for smashing walnuts, is also done, and in general it is more luxurious!123 Literature Network

Because it was a small hammer, the handle of the hammer was wood, and the hammer head was a large piece of irregular gold, and the purity of gold was very high, and it was heavy in the hand, at least 4 catties.

This weight knocks on the walnut just right!

"I'll go, little brother, you're a bit extravagant!" Lin Qingxuan took the golden hammer, this was the first time she had seen a hammer made of gold, smashed a walnut and tried it, it felt like that, it was not as good as an axe.

"Use this to make do with it first, and after a while, I'm going to smelt gold and make a jade seal. Zhao Yunxiang stretched out his finger very hiply, "The national seal made of gold, it must be cool to smash walnuts!"

"Hehe~!" Han Qianluo smiled, it was the first time he found out that Zhao Yunxiang actually had such a side, which was quite funny.

Lao Zhao's work has not yet been completed, and the finished panel has regained some moisture, after all, the huge wooden stakes have been exposed for a long time in the rainstorm, and they are all wet inside.

It takes a few hours in the sun!

Taking advantage of this time, he began to boil salt!

That's right, it's boiling salt!

Seawater contains a lot of salt, and the alkalinity is also very high, and there is a soil method to remove some of the alkali and retain the salt.

This method is not used to cook, but uses the temperature of the sun to evaporate, and the operation takes several days.

Lao Zhao didn't have so much time to make salt, so he started making salt according to his understanding.

First use a few clean bottles to pour a few bottles of seawater on the beach, the taste of seawater Lao Zhao tasted more than once or twice, salty, fishy, a little bitter~!

It is not difficult to make salt, just evaporate the water in the seawater, and the common methods of salt production include drying, etc.

The sun is very hot today, and a little bit of sea water on the scorching sand will soon dry out.

But Lao Zhao's approach requires a lot of seawater.

I saw this method on the Internet by accident, and many people said that it was very practical!

First, a bottle of seawater is poured into the basin, which has been blackened by fire, and although it is sanded and cleaned with sand every time it is used, the effect is not obvious.

Of course, these traces of fire smoke do not affect the use of pots!

Smoke burned under the mud stove, and about 500 milliliters of water were poured into the stainless steel basin.

Under the blowing of the sea breeze, the smoke of the fire whirred, and soon, bubbles appeared in the seawater in the stainless steel basin, and then the heat rose.

"Goo-goo~~!"

A large amount of water vapor gradually passed, and the water in the basin became less and less, and the original basin's waterline class clearly saw some white cloud-like traces, which were all alkalis in the seawater.

What Zhao Yunxiang did was to drain the alkali as much as possible and leave as much salt as possible.

The seawater was quickly evaporated, and at this moment, Lao Zhao poured the seawater again, and then stirred the basin to let the seawater merge.

The boiling sea water was quiet again, because a large amount of cold water had just joined.

After stirring the seawater to fully merge it, Zhao Yunxiang tilted the basin again and poured out a little seawater.

After several cycles like this, the seawater in the basin is almost evaporated, leaving only a thin layer of crystals.
