Two days later, Tong Zhenye hurried to Jiuding Mountain, and as soon as he saw Ren Qianqian, he picked him up and shook him straight.

"Master Ren, what are you talking about? Can you make salt?"

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

"Let me down ..." Ren Yaqian shouted, Tong Zhenye's claws were like iron tongs, and he was almost staring.

"Oh!" Tong Zhenye let go, and Ren Baqian fell directly to the ground and almost fell over.

"What resentment and resentment?" Ren Baqian's face was resentful, and then she was almost scattered.

"Master Ren, what was said before is true?" Tong Zhenye asked anxiously.

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

When the former Baqian said on the radio that salt can be made here, the official chat group of Dayao immediately became silent, and then there was a surprise and incredible voice.

After hearing the news, Tong Zhenye rushed to Shifu, asked some information, and then hurried over.

"Is there any salt?" Tong Zhenye asked.

"Wait until you come." Ren Baqian. "Relax, I have at least 80% confidence."

"Such a big thing must be done with 100% certainty," Tong Zhenye said in a deep voice.

"It's useless to say more, just try it out. Did you bring what you wanted?"

"Bring it." Tong Zhenye made two large buckets filled with water and milk, but in Da Yao's weather, it is now spoiled.

There are also cauldrons, sieves, and coarse cloth.

Ren Baqian also let people move out several vats, which is the brine that people have taken to two places in the past two days.

"A few help." Ren Baqian greeted the students, and several students rushed out.

At this time, a large circle of people surrounded the open space in the middle of the village, all of which were students, guards, and officials of the Ministry of Industry. Instead, the mountain people in the village were crowded out.

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 were unbelievable. Water is indeed salty, but it can also poison people.

Now it seems that another big official in the court has come.

"Write down the process." Ren Baqian reminded him, and then he was asked to pour black brine and yellow brine into a pot at a certain ratio, and I saw some small white crystals appearing under the basin soon.

"Sulfate in black brine and barium in yellow brine meet together to form barium sulfate that is insoluble in water." Ren Baqian said to the students next to him. Although they haven't learned these things, this is also a rare experimental experience.

Let people filter out the white crystals, and let eight thousand pairs of copper earthquakes say: "These barium sulfates must be kept in place and can be used elsewhere in the future."

After that was fried salt, Ren Baqian made a fire to boil the brine, then poured water and milk into it. It is more reasonable to use soybean milk, but soybeans are only cultivated in the southern part of the summer, called hoe, and the yield is not large.

And Da Yao didn't.

After asking on Earth, I knew that dairy products could be used instead. The price is expensive, but salt is even more expensive at Dayao.

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

Although the surrounding students were listening, they were completely unknown. I don't understand anything about protein, high-valent ions, barium sulfate.

This is true of students, especially those of Tong Zhenye and other ministries of industry.

However, I still tried to record the process.

Frying salt hasn't worked. The milk flavor in the pot is tangy first, which makes many people feel hungry.

"Did you bring rations? There are not so many people eating in the village." Ren Baqian reminded.

When Tong Zhenye came, he also brought dozens of people, and now there are more than 100 extra mouths in the village, all of which are of high strength and great appetite.

You must know that the higher the strength of the ancient people, the greater the appetite.

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

Tong Zhenye sacked his duty for eight thousand years, and he didn't need to remind him of this, Tong Zhenye knew more about these villages in the mountains than he did.

Next, everyone ate and waited. The village was always surrounded by such a large circle of people, but it just changed from standing to sitting on the ground.

Those mountain people were watching from a distance.

In the process of frying salt, from time to time, use a coarse cloth filter pocket to go deep into the water to remove the condensed impurities from it, so that it has been boiled for four hours before stopping to add water to it. The water gradually evaporates with the water. A layer of white crystals began to emerge from the walls.

"This is the salt made?" The spirit of Tong Zhenye, who watched for four hours beside him, was shocked, not only him, but also everyone else.

You should know that although there are only a few people at this time, two pots of pots can do things that affect the entire Dayao tens of millions of people.

"It's a little worse." Ren Baqiandao, after a while, when the water evaporated, people shove out all the white crystals in the pot, shake them on a dense bamboo sieve, and pour it down with water.

Most of the salt does not dissolve with watering, and almost all the impurities remaining in the salt are dissolved in the water and flow down.

"Now it's okay?" Tong Zhenye looked at the white layer of crystals on the bamboo sieve, his eyes lit up, as if he wanted to pounce on it.

Ren Baqian dipped his finger into his mouth, then nodded, "It's all right to dry."

Tong Zhenye said nothing. First, he put a finger on the salt and put it into the water. Then he laughed ecstatically: "I finally don't have to suffer from salt."

Not only him, but even those students cheered.

Dayao suffered from salt deficiency for decades. In that year, even because the salt was poisoned, it was knocked out of the mountains and destroyed the entire country. But even so, Dayao is still salt-free. For many years, both the people under the mountain and the people on the mountain have suffered from salt deficiency.

Over the years, salt has long been one of the most important resources in Dayao.

It is difficult for outsiders to understand the importance and desire for salt by Dayao people.

Although I haven't done anything other than fishing this time, I can see for myself that salt is made from these brines, and I can understand what this means to Dayao.

Just like the poor people suddenly discovered Jinshan.

Moreover, Ren Baqian is the governor of the university. The more powerful Ren Baqian is, the more they prove that their choice is correct, indicating that they can learn more.

The mountain people saw the people in the middle of the village as if they were crazy and cheered there, and they followed the commotion ~ lightnovelpub.net ~ because they all heard what Tong Zhenye said.

But they still have doubts in their hearts. Can this salt be eaten?

You know that the water in that black pool can poison people.

Ren Baqian watched them cheering there, and some smiles appeared on his face. Anyway, I did one more thing.

But before he laughed long, he couldn't laugh. Shi Gan and Du Lao Liu grabbed his hands and feet and threw him up.

Ren Baqian's eyes widened, you are happy, you throw people to celebrate, I can understand, but who has seen people throwing people to such a height of four or five floors?

Ren Baqian felt like he was on a dirt plane and was thrown up a dozen meters high, sending out a series of screams:

"Oh my day, I'm afraid I'm high!"

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

A slippery long sound cut through the whole village.
