Seeing her aggrieved look, Lin Xiaoxi's heart suddenly softened, and he reached out and touched her head.

I discovered that at some point, the little girl's withered and yellow hair not only began to become black and shiny, but also became soft and shiny. It was combed with two little pulls, which was very cute.

"Then why don't Sanxi and Fourth Uncle go and play with Sister Xiaoyu?"

Sanxi was a little moved, but when she thought of Ershi, who punched a hole in the tree, he shook his head in fear.

Ever since Er Shi came, she hasn't gone to play with Pai Pai for a long time...

When Lin Xiaoxi saw her like that, he knew what she was thinking, "Don't worry, Er Shi is much better now. As long as he doesn't get too close, Er Shi won't hurt you."

As he spoke, he gestured for her to look at the small stove at his hand, "Sister Xiaoyu said she wanted to make salt. Aren't you curious?"

Sanxi's eyes lit up. Even her fourth uncle said it was okay, so it must be okay!

Just as he was about to agree, Dagui had already left Wulang, who was still thinking hard, and ran away.

Flower ropes can be turned at any time, but salt making has never been seen before!

Of course I want to see Sister Xiaoyu making salt!

There were obviously not a few people who thought this way, and soon after, Wulang also chased after him.

Sanxi was so anxious that she stamped her feet.

It was obviously the fourth uncle who came to see her first, they are being shameless!!!

Seeing her friends all running away, Sanxi stood up quickly without being angry.

Skillfully, he put his arms around Lin Xiaoxi's neck and urged: "Uncle Fourth, go quickly, go quickly, I want to get a good position! We can't let them get there first!"

Lin Xiaoxi grabbed the stove aside with one hand and scooped up Sanxi with the other, and responded with a hearty smile: "Don't worry! The best seat must be our Sanxi's!"

Jiang Yu heard the movement behind him and said without looking back: "Put the stove on."

Lin Xiaoxi put down Sanxi and quickly set up the stove.

As soon as Sanxi stood firm, she made a face at Dagui and others who were still behind.

Humph, how can you guys with short legs outrun Fourth Uncle!

She was the first to arrive!

This excitement disappeared instantly when she turned around and saw Ershi and Paipai standing aside.

After secretly glancing at Ershi, Sanxi shrank her neck, then cautiously took a step forward.

Ershi didn't respond until he stood next to Jiang Yu. Sanxi breathed a sigh of relief and looked curiously at the bucket in front of Jiang Yu.

Jiang Yu sighed inwardly while stirring the solution in the bucket.

It's like a mountain separated us. Some things are easy to think about but difficult to do.

Originally, she thought that salt comes from sea water, so as long as the sea water is heated, coarse salt can be precipitated, and then refined salt can be obtained.

However, after she redeemed technical information on salt production in the knowledge mall.

I just felt like I was too naive!

Making salt seems simple, but in fact it is not that easy.

For example, she initially wanted to make salt by steaming it.

In theory it's no problem.

Table salt is actually sodium chloride.

The principle of making salt from seawater, simply put, is to evaporate excess water from seawater to obtain a saturated sodium chloride solution.

Then continue to heat, and sodium chloride crystals will precipitate, which is table salt.

However, the salt content of seawater is actually not as high as we imagined. It is only one-tenth of that of saturated sodium chloride solution, and it also contains a variety of impurities.

In other words, when you boil a pot of sea water, 90% of the water must be evaporated before the salt begins to precipitate.

How much charcoal will it cost and how long will it take to burn it?

Moreover, only coarse salt containing impurities can be obtained. The coarse salt produced in this way tastes bitter and is still far from the refined salt Jiang Yu wants.

As a qualified foodie, how could you possibly wrong yourself if you have the conditions?

Since we are going to do it, we naturally need to make refined salt with high purity!

So after careful consideration, Jiang Yu decided to skip the step of extracting coarse salt and purify it directly!

In Jiang Yao’s words, it’s just laziness!

Lazy Jiang Yu bought some coarse salt directly from the mall and planned to obtain refined salt through purification.

As for why not just buy refined salt?

Well, of course it’s because coarse salt is cheap!

The craftsmanship of making refined salt should not exist in this era, and the price is ten times that of coarse salt!

If you can purify it yourself, of course you can save a lot of money!

The second, and most important reason.

You can't slap Haikou in the face if you brag about it...

Think about what she vowed to Aunt Sun and the others yesterday?

Haha, you dug the hole yourself and filled it yourself.

Not only does it have to be filled in, but it can’t be filled in vain! Later she will have to find Aunt Sun and the others to witness the miracle!

…

Looking at the bucket in front of Jiang Yu, Sanxi was curious and forgot her fear, "Sister Xiaoyu, what is this?"

Jiang Yu said while stirring: "This is the water we will use to make salt later."

"Then where does this water come from?"

"Extracted from sea water."

Of course not!

This is a solution of distilled water and coarse salt.

At this time, the coarse salt underneath has stopped melting, indicating that it is saturated.

The preparations are all done, it’s time to gather the audience!

…

A group of people surrounded Jiang Yu and watched her twisting and turning, and then salt slowly began to precipitate.

"Look, look, look, something is really burning..."

Mrs. Sun looked surprised and her eyes shone, "This is salt! You are so expensive!"

You can actually do it yourself? It doesn’t look difficult...

If you could make your own salt, wouldn't it be possible to sell it for a lot of money?

If Jiang Yao knew what she was thinking, he would probably tell her that selling illegal salt is illegal.

But now, Mrs. Sun knew nothing about it. She looked at the salt grains that had just come out of the pot and said eagerly, "Xiaoyu, is this really salt? Can you get some for me to try?"

Jiang Yu concentrated on the movements of his hands and said without raising his head: "It's not working now. When it's done, I'll give it to everyone to try."

Although everyone looked at the increasing number of particles and did not understand the difference between this and the salt they usually eat, since Xiaoyu said so, they should wait patiently...

Until Jiang Yu poured a pot of saturated sodium chloride solution on the salt particles that had finally separated out...

Everyone couldn't help but want to stop it.

"Wait, Xiaoyu, what are you doing?!"

"Don't worry, we'll just wait and see." With that said, Jiang Yu poured the solution on decisively.

Then, amid exclamations of surprise, everyone discovered that the salt grains did not melt as expected.

"Eh?"

"Xiaoyu, is this... what kind of spell?"

Jiang Yu smiled and said: "No." This is actually the process of soaking in brine, but how should I explain it to them...

It's not that he can't think of ways to fool him, but... Jiang Yu looked at the group of children watching, these are the flowers of the future.

Therefore, in the spirit of cultivating children’s exploration of the truth.
