Two days later, Tong Zhenye hurried to Jiuding Mountain. When he saw Ren Baqian, he picked him up and shook him like he was catching a chicken.

"Sir Ren, what you said is true? Can you really make salt?"

Tong Zhenye's rough face was full of excitement and nervousness, for fear that Ren Baqian would say "no".

"Let me down first..." Ren Baqian shouted, Tong Zhenye's claws were like iron clamps, and he was almost shook his eyes full of stars.

"Oh!" Tong Zhenye let go and let Baqian land directly on the ground, almost falling.

"What kind of hatred or resentment?" Ren Baqian looked resentful and almost got separated just now.

"Sir Ren, what I said before is true?" Tong Zhenye asked anxiously.

"Can you still lie to you?" Ren Baqian said, rubbing his shoulders.

When Ren Baqian said on the radio that he could make salt here, Dayao's official chat group suddenly became silent, followed by a surprise and incredible voice.

After hearing the news, Tong Zhenye rushed to the Shi Mansion, first asked about some information, and then rushed over.

"Is there any salt made?" Tong Zhenye asked.

"I'll do it when you come." Ren Baqiandao. "Don't worry, I'm at least 80% sure."

"A big thing must be 100% sure." Tong Zhenye said in a deep voice.

"It's useless to say more, just try it out. Have you brought what you want?"

"Bring it." Tong Zhenye asked someone to lift two large buckets of buffalo milk inside, but in Dayao weather, it has deteriorated now.

In addition, there are large pots, sieves, and coarse cloth.

Ren Baqian asked someone to move out a few more big buckets, which was the brine that he had been taken back from two places in the past two days.

"Come and help." Ren Baqian greeted the students, and several students immediately ran out.

At this time, a large circle of people were surrounded by the open space in the middle of the village, all of which were students, guards, and officials from the Ministry of Works. Instead, the mountain people in the village were squeezed outside.

Most of them still don’t know what happened, but Nagu said before that they seemed to use the two kinds of toxic water to make salt, but most of them didn’t believe it. The water is indeed salty and may also poison people.

And now it seems that another large official from the court has come.

"Write the process down." Ren Baqian reminded him, and then someone poured the black brine and yellow brine into a basin in a certain proportion, and saw that some small pieces of white crystals soon appeared under the basin.

"The sulfate in the black brine and the barium in the yellow brine will form barium sulfate that is insoluble in water together." Ren Baqian said to the students next to him. Although they have not learned these contents, this is also a rare experimental experience.

When someone filtered out the white crystals, Ren Baqian paired the copper shaking nose said: "These barium sulfate should be kept and can be used elsewhere in the future."

Then, the salt was frying, and let the 8,000 people boil the brine and boil it, and then pour part of the buffalo milk into it. It is more reasonable to use soy milk, but soybeans are only planted in the southern part of the Great Xia, called soybeans, and the yield is not large.

And Da Yao has no.

After asking about the Earth, I knew that dairy products could be used instead. The price was very expensive, but salt was even more expensive in Dayao.

"The protein in milk can produce precipitates that can be filtered out with high-valent ions in brine, and can adsorb residue..." Ren Baqian continued to introduce.

Although the students around me listened, they were completely unaware of it. They couldn't understand proteins, high-priced ions, barium sulfate and so on.

This is true for students, especially for Tong Zhenye and other people from the Ministry of Works.

But I still tried my best to record the process.

The salt has not yet been effective, and the milky smell in the pot is so fragrant that many people feel hungry.

"Have you brought food? There are not so many people in the village who eat." Ren Baqian reminded.

When Tong Zhenye came, he brought dozens of people. Now there are more than a hundred mouths in the village, and they are all those with great strength and great appetite.

You should know that the higher the strength of the ancient tribe, the greater the appetite.

Although the hunting team had brought back some prey and the guards had caught some small beasts, the food in the village was still not enough for so many people to consume.

Tong Zhenye looked at Ren Baqian, and he didn't need to remind him that Tong Zhenye knew better about the situation of these villages in the mountains than he did.

Next, everyone waited while eating. There was always such a large circle of people in the middle of the village, but they went from standing to sitting on the ground.

The mountain people were watching from a distance not far away.

During the process of frying salt, you must occasionally use a filter bag made of coarse cloth to penetrate deep into the water to remove the condensed impurities. This way, after simmering for four hours, you will stop adding water to it. The water gradually evaporates, and a layer of white crystals on it begins to appear on the wall of the pot.

"Is this the salt made?" Tong Zhenye, who had been watching the side for four hours, was shocked. Not only him, but everyone else was like this.

You should know that although there were so many people at this time, they were doing things that affected tens of millions of people in Dayao.

"It's still a little bit." Ren Baqiandao, after a while, waited for all the water to evaporate, and asked someone to shovel out all the white crystals in the pot, put them on a dense bamboo sieve to shake them, and then pour them down with water.

Most of the salt did not dissolve with watering, while the remaining impurities in the salt were almost dissolved in water and flowed down.

"Now is OK?" Tong Zhenye looked at the remaining layer of white crystal on the bamboo sieve, his eyes lit up, as if he wanted to pounce on him and lick him.

Ren Baqian dipped his finger a little and put it in his mouth, then nodded: "Just dry these."

Tong Zhenye didn't say anything, first dipped a finger and put salt into the water, then laughed with ecstasy expression: "I, Dayao, finally, don't have to suffer from salt."

Not only him, but even the students cheered.

Da Yao's suffering of salt deficiency lasted for decades. It was even because salt was poisoned and the entire Hao Kingdom was destroyed. But even so, Da Yao still had no salt. For so many years, both the people at the foot of the mountain and the people on the mountain suffered from salt deficiency.

Over the years, salt has long become one of the most important resources in Da Yaoren's heart.

It is difficult for outsiders to understand Da Yaoren's emphasis and desire for salt.

Although I have never done anything except fishing this time, I have witnessed the use of salt from these brines and can understand the significance of this to Dayao.

Just like a poor person suddenly discovers a mountain of gold.

Moreover, Ren Baqian is the head of the school principal. The more Ren Baqian is, the more it proves that their choice is not wrong, which means that they can learn more.

The mountain people saw a circle of people in the middle of the village cheering like crazy, and they also became turbulent, because they all heard Tong Zhenye's words just now.

But they still wondered, can this salt be eaten?

You must know that the water in the Black Water Pond can poison people.

Ren Baqian looked at them cheering and smiled. No matter what, he did something else.

But before he could laugh for a long time, he couldn't laugh. Shi Gan, Du Laoliu and others grabbed his hands and feet and threw him up.

Ren Baqian's eyes widened, you are happy, I can understand that you are leaving people to celebrate, but who has ever seen someone so high as four or five floors?

Ren Baqian felt like he was riding a dirt plane, and was thrown up more than ten meters high, and let out a series of screams:

"My day, I'm afraid of heights-!"

"Whoever throws me again, I will shoot him--!"

A long sound resounded throughout the village.
