Two days later, Tong Zhenye hurried to Jiuding Mountain, and as soon as he saw Ren Baqian, he picked him up like a chicken.

"Lord Ren, what you said is true, can you really make salt?"

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

"Let me go first......" Ren Baqian shouted, Tong Zhenye's two claws were like iron tongs, and his eyes were about to be shaken full of stars.

"Oh!" As soon as Tong Zhenye let go, Ren Baqian fell directly to the ground, almost falling on his head.

"What kind of grudge?" Ren Baqian had a grudge on his face, and he was almost shaken apart.

"Lord Ren, is what you said before true?" asked Tong Zhenye anxiously.

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

When Ren Baqian said on the radio that salt could be made here, Dayao's official chat group was silent for a moment, followed by a voice of surprise and disbelief.

After hearing the news, Tong Zhenye rushed to Shifu, asked some questions about the situation first, and then hurried over.

"Is there any salt that has been made?" asked Tong Zhenye.

"I'll do it when you come. "Ren 8000. "Don't worry, I'm at least eighty percent sure. ”

"For such a big thing, you have to be 100% sure. Tong Zhenye said in a deep voice.

"It's useless to talk too much, just try it and you'll know, did you bring what you want?"

"Brought. "Tong Zhenye asked people to carry up two large buckets, which were filled with buffalo milk, but in the weather of Dayao, it was already spoiled.

In addition to this there is a cauldron, a sieve, a coarse cloth.

Ren Baqian asked people to move out a few large barrels, which was the brine that people had to get back from two places in the past two days.

"A few helpers. Ren Baqian greeted the students, and immediately several students ran out.

At this time, a large circle of people surrounded the open space in the middle of the stockade, all of whom were students, guards, and officials of the Ministry of Works, but the mountain people in the stockade were all squeezed outside.

Most of them still don't know what's going on, but Nagu has said that they seem to be going to make salt from those two poisonous waters, but most of them don't believe it. The water is indeed salty, but it can also poison people.

And now it seems that there is another big official in the court.

"Write down the process. Ren Baqian reminded him, and then asked people to pour the black brine and yellow brine into a basin according to a certain proportion, only to see 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 meet together to form barium sulfate, which is insoluble in water. Ren Baqian said to the student next to him. Although they haven't learned this yet, it's a rare experimental experience.

Let the white crystals be filtered out, Ren Baqian said to Tong Zhenye: "These barium sulfate should be kept and packed, and they can be used elsewhere in the future." ”

After that, the salt is fried, and after Ren Yaqian makes a fire to boil the brine, he pours some buffalo milk into it. It is reasonable to use soy milk, but soybeans are only planted in the southern part of Daxia, called soybeans, and the yield is not large.

And Da Yao didn't have it at all.

After asking when on Earth, I learned that I could use dairy instead. The price is very expensive, but the salt is even more expensive in Da Yao.

"The protein in the milk can produce a precipitate that can be filtered out and adsor......b residues with high-valence ions in the brine," Ren continued.

Although the students around them listened, they didn't understand why at all. Proteins, high-valent ions, barium sulfate and anything else are completely incomprehensible.

This is true for all students, and even more so for Tong Zhenye and other people from the Ministry of Engineering.

However, I still tried to record the process.

The frying salt has not yet achieved results, and the first milky smell in the pot makes many people feel hungry.

"Have you brought rations? There is nothing to eat for so many people in the village. Ren Baqian reminded.

Tong Zhenye also brought dozens of people with him when he came, and now there are more than 100 extra mouths in the village, and they are all the ones with great strength and great appetite.

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

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

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

Then everyone ate and waited, and there was always such a large circle of people in the middle of the stockade, but it changed from standing to sitting on the ground.

The mountain people were watching from a distance.

In the process of frying salt, from time to time with a coarse cloth made of strainer bag deep into the water to fish out the condensed impurities, so that it has been boiling for four hours before stopping adding water to it, the water is gradually evaporated, and a layer of white crystals on the wall of the pot begins to be exposed.

"Is this the salt that is made?" Tong Zhenye, who had been watching from the side for four hours in a row, was shocked, not only him, but everyone else as well.

You must know that although there are so many people and two pots at this time, what can be done is to affect tens of millions of people in the entire Dayao.

"It's a little bit worse. After a while, when all the water had evaporated, people scooped out all the white crystals in the pot, shook them on a dense bamboo sieve, and then poured them down with water.

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

"Is it okay now?" Tong Zhenye looked at the remaining layer of white crystals on the bamboo sieve, his eyes lit up, as if he wanted to pounce on it and lick it.

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

Tong Zhenye didn't say a word, first dipped a finger of salt into the water, and then laughed with ecstasy: "My Dayao finally doesn't have to suffer from salt." ”

Not only him, but even the students cheered.

Da Yao suffered from a lack of salt for decades, and it was even because the salt was poisoned that he was beaten down from the mountains and wiped out the entire Hao country. But even so, Dayao still has no salt, and for so many years, both the people under the mountain and the mountain people on the mountain have suffered from a lack of salt.

Over the years, salt has long become one of the most important resources in the hearts of Dayao people.

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

Although I didn't do anything other than fishing this time, I saw the salt made from these brines, and I could understand what it meant to Da Yao.

It's like a poor man suddenly discovering a mountain of gold.

Moreover, Ren Baqian is the head of the school, and the more powerful Ren Baqian is, the more it proves that their choice is not wrong, indicating that they can learn more things.

The mountain people saw that a circle of people in the middle of the village were cheering like crazy, and they also started to stir, because they had heard what Tong Zhenye had said just now.

But they still have doubts in their hearts, can this salt be eaten?

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

Ren Baqian watched them cheer there, and there was a smile on his face. Anyway, I did another thing.

But before he could laugh, he couldn't laugh anymore. Shi Kang, 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 ever seen someone throw people four or five stories so high?

Ren Baqian felt as if he was on a dirt plane, and was directly thrown up more than ten meters high, letting out a series of screams:

"My day, I'm afraid of heights——!"

"Whoever throws me again, I'll shoot him——!"

A long sound permeated the entire stockade.
