Hongyu and Wang Ziteng, one after the other, walked towards the fields outside the village.

They have been in Wangjia Village for so many years, they are familiar with every place here, and they know where the saline-alkali land is.

Soon, there was a place.

As far as the eye can see, this is a wasteland, and on the surface of the wasteland, there is a layer of snow-white dandruff-like things.

This wasteland is not without growing things, but it is useless to plant things, it is difficult to grow anything at all, and the layer of snow-white things is the layers of salt and alkali seeping out of the ground.

Such salt and alkali, after scraping away, can be used for consumption after some treatment.

Naturally, this method of dealing with salt alkali has been controlled by salt merchants and officials, ordinary people do not know the method of salt production at all, salt is a controlled product, and the Tiantong Dynasty strictly prohibits private salt production.

This wasteland is very low-lying, with poor drainage, coupled with strong evaporation, salt continues to accumulate on the surface, and over the years, the hydrological and geological conditions have deteriorated seriously, making it no grass.

However, in such a place, there is naturally more salt.

Wang Ziteng walked into the ground, found a place with thick salt, bent down, twisted it with his hand, grabbed a handful, and sprinkled it into the air, dust and salt leaked from the tips of his fingers, and white powder flew and sprinkled.

"Hongyu, let's pile up a layer of white powder on the surface of the earth, and after a certain amount of treatment, the white powder can get refined salt. ”

Hongyu nodded, when she came, she had already prepared her tools, and when she heard this, she picked up the broom, smoothed the ground, and swept it up gently, gathering the salt all over the ground.

Then it was put in a big bag, full of it, the gap in the bag was very small, Wang Ziteng pulled up the bag, and carried it on his back, except for the beginning, when the dust flew and spread all over the prince, and then no dust came out of the bag.

Carrying a bag of salt and alkali on his back, the prince took a stride and walked towards his home.

"With so much salt and alkali, after processing, how can you get a lot of refined salt, and with these refined salts, you can also have a taste for stir-frying during the New Year. ”

When he got home, Wang Ziteng put down the bag and found a cauldron, a spoon, and a few pieces of coarse cloth, and Hongyu stood quietly and watched.

I wanted to avoid it a few times, but I couldn't help but stay, and seeing that Wang Ziteng didn't let me leave, I didn't know what I thought of, and my face couldn't help but blush.

After the cauldron was placed and filled with water, Wang Ziteng poured a bag of white powder into the cauldron, and then used a wooden stick to muddy the water.

"You can make salt now, and there are no tools here, so you can only make it roughly, but even if it is rough and rough, it is much better than the salt you eat now, and if you have tools in the future, we will refine it." ”

After muddying the water, Wang Ziteng moved another large vat, took the coarse cloth taken out of the house, circled it around the mouth of the vat, tied it tightly with a thick rope, and then gently put his hand in the middle of the coarse cloth, and pressed it hard.

"That's it!"

Wang Ziteng bent down to pick up the spoon, scooped out the muddy water, spoon by spoon, and poured it on the coarse cloth, rinsing the impurities in the salt water.

After slowly eliminating some coarse impurities, then pour the salt water in the vat into the cauldron again, set up a shelf, put the cauldron on the shelf, and make a fire.

Constant boiling evaporates the water in the cauldron to separate the salt water, again and again, so that the water inside evaporates cleanly, and there are layers of snow-white edible salt left in the pot.

The salt made in this way is already edible salt that can be used.

These jobs were basically done by Wang Ziteng alone, and Hongyu watched from the side, occasionally picking up some firewood and the like.

Wang Ziteng was alone, adding firewood to make a fire, evaporating water, and the boiling fire burned, reflecting Wang Ziteng's face red, and his red face was full of smiles.

"As long as the water in it is completely evaporated, you can get edible salt. ”

Evaporated over and over again, time passed, and before I knew it, it was noon, and at this time, the water in the pot had finally evaporated, and a layer of snow-white crystals shimmered with a weak luster under the sunlight.

"That's it!"

Wang Ziteng was excited, he didn't care about the heat of the pot, stretched out, gently twisted a little salt with his hand, put it in his mouth, and lightly added it, and a salty taste came from the tongue bud.

"Yes, that's good salt!"

Hongyu looked at the snow-white salt in Wang Ziteng's hand, and couldn't believe it, the salt she got from the big family was a little yellow.

And the salt in the prince's hand was as white as snow, and it looked very exquisite.

"Is this the cure for haode salt, can you eat it?"

Hongyu walked to the pot and looked at the salt in the pot, her eyes moistened.

If these salts can really be eaten, there are really no side effects, it is a magnificent achievement for thousands of generations, and from now on, people no longer have to worry about poisoning and dying because of eating salt containing impurities for a long time.

"Yes, this is a simple salt, you eat it to see if it tastes much better than the salt in your hand. ”

Wang Ziteng smiled, took out a little salt from the pot, and handed it to Hongyu, Hongyu's face turned red, took it, put it in his mouth, the salt melted in his mouth, and the pure salty taste came from his mouth.

"It's really salt!"

Hongyu felt that it was dreamy, and the refined edible salt that countless people had not made was actually made by Wang Ziteng with such a simple drum.

Moreover, she was right next to her, witnessing the moment of miracle, but she was shy in her heart.

"Such a precious method, why didn't he let me avoid it, just let me learn it secretly, he wasn't afraid that after I learned it, he would kill him and monopolize this skill. ”

Salt is like gold, it is very expensive, and ordinary people can't afford to use some better salt.

If you can master the art of salt making, it is equivalent to mastering the art of alchemy, and the salt mines, sea salt, and well salt in the mountains and rivers all over the world will be turned into white flowers and silver, which will be inexhaustible.

Wang Ziteng didn't notice what Hongyu was thinking at all, so he took an urn and put the salt in the pot, and the salt in the small half urn was enough to support the end of the New Year.

"Hongyu, you go home and find something, and I'll give you half of the salt. ”

Hongyu shook her head: "This thing is too precious, I can't ask for it!"

Wang Ziteng smiled: "It's just some salt, it's nothing, if you want it, this thing, as long as we have time, we can get as much as we want." ”

"When I have a certain reputation, I will spread this method of making salt, so that more people in the world can use more haode salt. ”

Hongyu was silent, looking at the somewhat high-spirited Wang Ziteng, and suddenly felt that the figure of the young man in front of him was so tall, with all the people in mind and helping the world.
