I was a village chief in a primitive society

Chapter 469: Just dry it in the sun. (4 more please customize)

"But Wu, it was too dark at night, and we couldn't see clearly that there were no people in the tribe."Coco expressed her worries.

"It’s not a big problem. If people from your tribe survived, they must have been arranged to be slaves."

Su Bai paused and continued:"It's definitely impossible to live in a wooden house. The most you can do is sleep in a tent outside, and you will probably work at night. It shouldn't be difficult to find it."

"I know, then I will definitely try my best to do this well."Coco said seriously.

The girl who originally looked very calm and quiet suddenly became extremely serious and determined.

Coupled with the girl's clean short hair, this expression became even more perfect.

"Don't think too much about it. Let's go out to dry the salt first. Once we have planned the salt drying, we will discuss your tribe's affairs."Su Bai said softly.

The main purpose of coming out this time is to dry the salt. Things that can be done immediately must be arranged first.

As for snatching back the sea fish tribe or observing the seaside tribe, everything has to wait until the salt is dry. Let’s talk about the salt thing after we get it sorted out

"yes."Coco nodded.

"There are no tribes on the beach or it is far away from the tribes."Su Bai asked.

Since we are going to bask in the salt, we must not let other people know about it. Everything must be kept secret.

"Fly forward, all the way to the end. There are almost no peeling tribes there, because it is too far away and ordinary people cannot reach it."Coco pointed to the front left and said

"OK, just go there."Su Bai nodded and said

"Huhuhu......"

The hot air balloon started to fly towards the left front under control, and it took several hours to get there.

After Su Bai saw that place, he finally understood why no one could get there.

Because although there is a large open space there, there is also a high cliff in the middle.

If you want to climb over that cliff, it will definitely take a lot of time, and it will also be very dangerous.

However, this cliff obviously provides good help for drying salt. As long as the tribesmen dry salt here, they will not be discovered.

The hot air balloon began to descend slowly under skillful operation, and finally stopped on the beach.

"Wu, how to dry the salt? Sha Lan asked curiously.

When the cat-eared girl stepped on the beach, she felt an unprecedented softness.

This was a feeling that the land in the forest could not give her. The sand would sink as soon as she stepped on it. It feels so strange.

Moreover, the sand looks thin and white, and it is also very beautiful. It is completely different from the land I usually walk on.

Others also observed their feet one after another, and some even started to lower their heads. Playing with the sand

"It takes steps from seawater to evaporation pond, crystallization pond, coarse salt and mother liquor to produce salt."Su Bai said professionally.

On the other side of the earth, the main method of extracting salt from seawater is the"salt field method", which is an ancient and widely used method.

"So what to do? Will it be complicated?" Sha Lan asked later.

"Choose an area with a mild climate and plenty of sunshine, and choose a large flat beach to start building salt fields."Su Bai said

"Salt fields? Wu, what is a salt field? Sha Lan continued to ask

"A salt pan is a place where salt is dried and is generally divided into two parts: an evaporation pond and a crystallization pond."Su Bai explained simply.

Anyway, there are too many girls who don't understand it, so I'll just give it a rough explanation.

In fact, the salt field mainly introduces seawater into the evaporation pool. When the evaporated water reaches a certain level in the sun, , pour into the crystallization tank.

Then the seawater will turn into a saturated solution of salt, and then the salt will gradually precipitate out under the sunlight. The resulting crystals are our common coarse salt, and the remaining liquid is called mother liquor, from which various chemical raw materials can be extracted

As early as the ancient Chinese nation on earth, coastal residents used seawater to make salt, introduced seawater into salt fields, and concentrated the seawater through the evaporation of sunlight and wind, making it saturated and further crystallizing the salt. In fact, these steps are not too complicated. Difficult, the most important step is to make the salt field

"Wu, where should we choose the salt field? Sha Lan looked around and found sand everywhere.

Su Bai also carefully observed the surrounding environment, and finally found a suitable place for salt fields in a place with less sand.

He found that here The soil content is relatively high, and he said:"Let's set up the salt field here and start digging holes.""

"yes."The preparatory soldiers immediately nodded and started digging the pit.

Since they just wanted to test it first, and then dry some salt for use in heavy ice and snow.

Therefore, the salt field was not dug very large, and it did not take a long time, about twenty minutes. Just finished digging

"Continue to dig a channel all the way to the sea."Su Bai continued to order.

What we have to do now is to introduce seawater into the evaporation pool so that we can start drying the salt.

"yes."What started to pick up the hoe and start digging the channel again, this time I brought the tool with me when I came out.

In ten minutes, a long channel was dug, and the seawater began to be slowly introduced into the sun along the channel. Inside the salt pond

"Just watch here. When the seawater is slowly dried, crystals will form. Then......."Su Bai began to explain to the preparatory soldiers.

After all, he only needs to hand over the knowledge to them, and then they will watch.

I have to rush back to the tribe, so I can't spend too much time here.

And drying salt cannot be completed in a short time, so you need to explain it in advance.

"yes."The preparatory soldiers nodded seriously.

Ten minutes later, after Su Bai finished explaining, he ordered to start preparing to find a place to live.

We still have to sleep at the beach tonight and wait until early tomorrow morning before setting off..

And tonight, the blond girl is asked to go to the Sea Insect Tribe to see if there are any survivors from the Sea Fish Tribe.

"Huhuhu......"

The hot air balloon took off again and began to fly towards the forest. After all, it would be too cold at night at the beach, and the smell of the sea was so strong that it was impossible to sleep.

More than an hour later, the hot air balloon stopped at a secret place in the forest.

Some of the preparatory warriors began to set up tents, while others began to hunt and prepare food for the night.

"Wu, can you produce salt just like this? Sha Lan asked curiously.

When they were digging the salt pond and explaining the salt drying method, the cat-eared girl listened very carefully.

"Of course, you can just watch it when the time comes."Su Bai smiled and said.........................................
