After hearing Nagu's words, Ren Baqian was quite sure.

When he heard the toxic salt water just now, he had an idea. Although it was toxic, all the substances in the world were composed of ions and molecules, so chemical reactions would inevitably occur under certain conditions.

That is, the salt can be extracted or the toxicity can be eliminated.

And that black water also smells of smelly eggs, it is probably a kind of black brine. There is this kind of thing on the earth, and it was crystallized by ancient people using wisdom to refine and use it nearly two thousand years ago.

This is the predecessor of the famous "jing salt". After understanding some of the situations in this world, he specially checked various information about well salt. In fact, it is not only the seaside that can produce salt. People in Sichuan, Tibet and other places use various methods to extract salt, a necessary material for daily life, from nature.

There are also various methods. The salt crystallization of natural brine on the surface and salt-alkali land is the simplest. If there are no such conditions, many other methods are used to make salt, and well salt is one of them.

Among them are black sanitary wells, yellow sanitary wells, and Shiyan wells. They mainly extract seawater accumulated underground after the evolution of the earth's crust. Or metamorphic seawater.

Among them, black brine well refers to this toxic black brine. This spoiled seawater is generally below 300 meters underground, but it will also form springs or pools by chance due to earthquakes or other reasons.

It was precisely because of this that Ren Baqian immediately thought of this when he heard them say the poisonous salt water.

"Then do you have that kind of brown water there? It's also salty and poisonous." Ren Baqian asked immediately.

The reason why I ask this is because there are a large amount of sulfate in the black halogen, and barium ions in the yellow halogen. Both types of brine are toxic to the human body. However, if they are fused together in a suitable proportion, the sulfate and barium in it can be turned into barium sulfate to crystallize, eliminate toxicity, and extract well salt.

Of course, the premise is that the black water pool is indeed black brine. And there are no other toxic ingredients in it.

According to a few words just now, Ren Baqian felt that the first point is very likely, but it is hard to say the second point.

"No." The man said coldly. Even if he knew that Ren Baqian was working in the Beast Garden, he would just make him less hostile, which does not mean that he would be kind to Ren Baqian. In fact, Ren Baqian looked thin and weak, and looked similar to those of Yunguo and Daxia people. He would not like such a person. This is already deeply rooted in his bones.

"Yes!" Nagu suddenly remembered something and turned to retort to the big man: "The one in the mountain we met last time, Dagong took a sip and didn't have the strength for the whole afternoon. He shot the tooth beast's face with an arrow, which almost made you penetrate the tooth beast. Isn't that water just what he said?"

"Hmph" the big man snorted coldly and turned his head away.

Nagu turned to look at Ren Baqian and said, "There is a gap in the mountains that you said, but it only has a little brown color and cannot be drunk."

Ren Baqian was delighted after hearing her words.

I just asked by the way, but I didn't expect that there was actually.

"Where is your village?" Ren Baqian asked.

"What are you doing?" Nagu immediately became alert.

"I don't know where your village is. Where can I find the Black Water Pond and the other water you mentioned?" Ren Baqian said.

"What are you looking for this thing? Do you think it can be used as salt? I told you it's poisonous." Nagu looked at Ren Baqian with a suspicion.

"Since it is poisonous, then there is a way to detoxify. Everything in the world is mutually generated and restrained."

"Hmph, don't believe it!" Nagu said directly.

"You have to try it before you know. If you really look for it, hire you as a guide and use salt as avenge, what about?" Ren Baqian lured it for profit.

Nagu's eyes rolled, and he stretched out a finger and said, "I'm a good hunter. I want to hire me as a guide. I need at least half a pound of salt a day."

Ren Baqian looked at her stretched out finger and thought about what she said, very curious. What should she do if she wanted a pound of salt? Extend two fingers?

Thinking of this, Ren Baqian subconsciously stretched out two fingers: "How many are this?"

Nagu was stunned at first, then furious: "Do you think I am a fool?" He directly showed his fist that was bigger than the woman on earth, and did not forget to bare his teeth at Ren Baqian, like an angry cat.

Ren Baqian estimated that Da Yaoren's strength would be great, and then looked at Nagu's fist. If he was beaten by such a small fist, he would even vomit his liver.

"Half a pound of salt, agreed." Ren Baqian immediately changed his words.

"Hmm? Well, if you have a hunter as good as me as a tour guide, you will make a lot of money!" Nagu retracted his fist, raised his face, raised his chest and raised his head proudly.

"Are you really from the Beast Garden?" Nagu thought about it and asked again.

Ren Baqian took out a sign in his arms: "Look at it yourself."

"I don't know, I can't understand." Nagu spread his hands.

"I told you a long time ago that this is the manager Ren from the Beast Garden. Can you still pretend to be a fool to lie to you?" Tiedao said.

Nagu looked at Tiedao, then looked at Ren Baqian, and then said, "Believe in you first. Our village is in Jiuding Mountain. You can get there for a day after you leave the city and walk southwest. There is a Luo Wengjiao below the mountain. I heard it when it sounds."

"What corner at the foot of the mountain? Where can I find it?" Ren Baqian said. What corner at the foot of a mountain? How can I find it? What is the difference between looking for a needle in a haystack?

"It's not a ke, it's Luo Wengjiao. You don't even know Luo Wengjiao? There is a stick standing at the foot of the mountain, and Luo Wengjiao is hanging on it." Nagu stared at Ren Baqian with wide eyes.

Ren Baqian saw Nagu with an expression that you were an alien, and even Luo Wengjiao didn't know about it. He turned his head and looked at the iron knife: "What is Luo Wengjiao?"

"Luoweng is a wild beast in the mountains, with a single horn, as fast as lightning. The horn on his head is taken off and blown and can be transmitted for ten miles." said Iron Knife.

"Can it really spread from ten miles?" Ren Baqian looked suspicious. What is the concept of ten miles? Ten miles are only five kilometers, and it takes about an hour to walk.

Even if it is an open place in the wild, it will take about 1230 to reach five kilometers.

Probably the sound of the plane taking off or the sound of thunder.

Ren Baqian was a little unbelievable if a beast horn could blow such a loud sound.

The iron knife ticks: "There are usually big-eared monkeys in the mountain village. If you can hear the sound from Luo Wengjiao in the distance, the people in the village will know that there are guests coming."

Ren Baqian suddenly realized.

Turning around, Nagu wanted to ask where Luo Wengjiao was. She probably couldn't explain it clearly, so she simply stopped asking.

"Since that's the case, let's go back first. If you go to find the Black Water Pond, then go to Jiuding Mountain to find you."

"Remember to bring salt." Nagu reminded.

"I can't forget it. Then, say goodbye." Ren Baqian bowed.

After walking out for a while, Teng Hulu asked, "Ren, can the Black Water Pond really get salt?"

"It's not Tao, it's refining. As for whether it can be extracted harmless, it depends on the situation." Ren Baqian said. He was not very sure, so he could only say half of it.

"It would be great if that would be." Teng Hulu was a little excited.

"Your Majesty agrees to this matter." Ren Baqian said slowly.

"As long as the manager has a way, your Majesty will definitely support him." Teng Hulu said. "There will definitely be rewarded for official positions."

Ren Baqian grinned. This was one of the reasons why he asked about this. Since he came here, he couldn't be a manager in the Beast Garden all the time, right? Or can he satisfy himself by making some earth things to make a few money?

If he was in a world similar to the ancient Chinese country, he might have really done that. It is nothing wrong with being leisurely and at ease.

However, there are too many unknowns in this world. Without status, you will definitely not be able to understand too much.

For example, he has never seen that Qilin again until now. I heard that there is a dedicated person in charge in the palace.
