After listening to Na Gu's words, Ren Baqian felt quite sure.
When he heard the poisonous salt water just now, he had an idea. Although it is poisonous, all substances in the world are composed of ions and molecules, so chemical reactions will inevitably occur under certain conditions.
That is to say, the salt in it can be extracted, or the toxicity can be eliminated.
And that kind of black water smells like rotten eggs. It is probably a kind of black brine. There is such a thing on the earth, and it was refined and used by the ancient people nearly two thousand years ago using the crystallization of wisdom. up.
This is the predecessor of the famous "Well Salt". After learning about the situation in this world, he specifically inquired about 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 life, from nature.
There are also various methods. Surface natural brine drying salt and salt crystallization in saline-alkali land are the simplest. If such conditions are not available, many other methods are used to produce salt, and well salt is one of them.
Among them, there are black brine wells, yellow brine wells, Shiyan wells and so on. It is mainly to extract the seawater accumulated underground after the evolution of the earth's crust. Or metamorphic seawater.
Among them, the black brine well refers to this poisonous black brine. This kind of metamorphic seawater is generally below 300 meters underground, but springs or pools can also be formed by accident due to earthquakes or other reasons.
It is precisely because of knowing this that Ren Baqian immediately thought of this when he heard them mention 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 lot of sulfate radicals in black brine, and barium ions in yellow brine. Both brines are poisonous to the human body, but if they are mixed together in an appropriate proportion, the sulfate radicals and The barium turns into barium sulfate crystals, which removes the toxicity and extracts the 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 the few sentences just now, Ren Baqian felt that the first point was very likely, but the second point was hard to say.
"No". The big man said coldly, even if he knew that Ren Baqian was working in the beast farm, it only made him less hostile, it didn't mean he would be kind to Ren Baqian. In fact, Ren Baqian has a thin and thin body, and he looks similar to Yunguo people and Daxia people. He would not like such people. This is already deep into the bone marrow.
"Yes!" Nagu suddenly remembered something, and turned to retort to the big man: "The one in the mountains we met last time, Da Gong drank a sip of thirst, and he didn't have the strength all afternoon, so he shot an arrow directly into the face of the toothed beast It’s on, and you were almost pierced by the tooth beast. Isn’t that water what he said?”
"Humph" the big man snorted coldly and turned his head away.
Nagu turned to look at Ren Baqian and said, "There is a crevice in the mountain where the water is just like what you said, but it's just a little brown, so it's not drinkable."
Ren Baqian was overjoyed when he heard her words.
I just asked by the way, I didn't expect it to be true.
"Where is your stockade?" Ren Baqian asked.
"What are you doing?" Nagu immediately became vigilant.
"I don't know where your stockade is, where can I find the black water pool you mentioned and the other water?" Ren Baqian said.
"What are you looking for? Do you think it can be used as salt? I told you that it is poisonous." Na Gu looked at Ren Baqian suspiciously.
"Since it is poisonous, there is a way to detoxify it. Everything in the world is mutual generation and mutual restraint."
"Hmph, don't believe me!" Na Gu said directly.
"You have to try to find out. If you really look for it, how about hiring you as a guide and using salt as a revenge?" Ren Baqian lured him into profit.
Nagu rolled his eyes, stretched out a finger and said, "I'm a good hunter. If you want to hire me as a guide, you need at least half a catty of salt a day."
Ren Baqian looked at a finger she stretched out, thinking about what she said, very curious, what would she do if she wanted a catty of salt? Stretch two fingers
Thinking of this, Ren Baqian subconsciously stretched out two fingers: "How much is this?"
Na Gu was taken aback for a moment, and then furiously said, "Are you taking me for a fool?" He directly showed his fist that was a circle bigger than a woman on Earth, and did not forget to bark his teeth at Ren Baqian, and followed the irritated cat like.
Ren Baqian estimated Dayaoren's strength, and then looked at Nagu's fist, and estimated that if he was hit in the chest by such a small fist, he would vomit out his liver.
"Half a catty of salt, I agree." Ren Baqian immediately changed his words.
"Huh? Well, if you have a good hunter like me as your tour guide, you'll make a lot of money!" Nagu retracted his fist, raised his face, and proudly raised his chest.
"Are you really from the animal garden?" Nagu thought for a while and asked again.
Ren Baqian took out a sign in his arms: "See for yourself."
"I don't know, I don't understand." Nagu spread his hands.
"I told you earlier, this is the steward of the beast garden, how could he pretend to lie to you?" Tie Dao said on the side.
Nagu looked at Tie Dao, then at Ren Baqian, and then said: "Believe in you first. Our village is on Jiuding Mountain. You can go out of the city and walk southwest for a day. There is Luowengjiao at the bottom of the mountain. , I heard it when it blew."
"What corner under the mountain? Where can I find it?" Ren Baqian spread his hands. How could it be possible to find a corner under a mountain? How is it different from finding a needle in a haystack
"It's not a horn, it's the horn of Luo Weng. You don't even know the horn of Luo Weng? There is a stick at the bottom of the mountain, and the horn of Luo Weng is hanging on it." Nagu stared at Ren Baqian with wide eyes.
Ren Baqian saw Na Gu's expression that you are an alien, you don't even know Luo Wengjiao, and turned to look at Tie Dao: "What is Luowengjiao?"
"Luo Weng is a wild animal in the mountains. It has a single horn and is as fast as lightning. When the horn is taken off, it can be blown for ten miles." Tie Dao said.
"Can it really spread ten miles?" Ren Baqian looked skeptical, what is the concept of spreading ten miles? Ten miles is five kilometers, and it takes almost an hour to walk.
Even if it is an open place in the wild, it takes about one hundred and twenty thirty decibels to travel five kilometers.
Probably the sound of an airplane taking off, or the sound of thunder.
Ren Baqian couldn't believe that a horn could blow such a loud sound.
Tie Dao clicked his mouth: "In the village, there are usually big-eared monkeys and the like. If you can hear the sound from Luowengjiao in the distance, the people in the village will know that there is a visitor."
Only then did Ren Baqian suddenly understand.
Turning to look at Nagu, she wanted to ask where the Luoweng Point was, but she probably couldn't tell clearly, so she simply didn't ask.
"Since this is the case, let's go back first. If we are looking for the black water pool, we will go to Jiuding Mountain to find you."
"Remember to bring salt." Na Gu reminded.
"I can't forget it. Then, farewell." Ren Baqian cupped his hands.
After walking a certain distance, the rattan gourd asked: "Steward Ren, can the black water pond really yield salt?"
"It's not scouring, it's refining. As for whether it can be refined and harmless, it depends on the situation." Ren Baqian said. I don't have much confidence in my heart, I can only say half and half.
"It would be great if that's the case." Rattan Gourd was a little excited.
"This matter requires His Majesty's approval." Ren Baqian said unhurriedly.
"As long as Steward Ren has a way, His Majesty will definitely support it," said Vine Gourd. "There will definitely be official rewards."
Ren Baqian grinned. That's one of the reasons he asked about it. Now that you're here, you can't always be a steward in the beast garden, can you? Or get some earth stuff to make a few bucks and be satisfied
If it was in a world similar to the ancient Hua Kingdom, he might really do that. It's laid back and there's nothing wrong with it.
But there are too many unknowns in this world. And without status, you definitely can't understand too much.
For example, he hasn't seen that unicorn until now, and it is said that there is a special person in charge of it in the palace.
In addition, in this powerful world, the difference between himself and others makes it difficult for him to feel safe. And status obviously brings a certain sense of security.
