"No, no, no, it doesn't mean that, it's that the earth is affected by this force, but the way it moves is not just falling down. I'll talk about that later, as long as you have that concept first.

To put it simply, when the earth moves, it creates a variety of situations, such as raising a mountain range on a flat land, turning an ocean into a plain, leveling a mountain range, and so on. Of course, this time is very long, measured in tens of thousands of years. ”

"One of them is that the ocean becomes plains or mountains, and the sea water is swallowed up into the ground without time for the earth to evaporate, and after countless years of some changes, it is finally discovered by chance. "Ren 8000.

"Teacher, do you mean that this was originally the ocean?" Shi Dang asked, Ren Baqian's words were too surprising.

You must know that this is the inland of Dayao, and it takes thousands of miles to reach the seaside. This was originally an ocean? So doesn't it mean that the place where Da Yao and Yun Guo are located was originally an ocean?

"There is this possibility, it's just a guess, and it depends on what the composition of the black water in this black pool is. Ren Baqian nodded.

The crowd was stunned at first, and then asked, "And then, let's prove this?"

"Then, you should know that salt is obtained from seawater......" As soon as Ren Baqian's words came out, everyone was shocked and asked, "Can salt be made here?"

Dayao is short of salt, even if it is a child who knows it, most of the salt needs to be shipped from other countries. If salt can be produced here, most of these children know what it means.

"It depends on what the water is made of. Ren Baqian didn't say too much, but the light licking of Fang just now has proved that there is indeed salt in this water, but we need to see if we can make edible well salt.

"What do you think the water is made of?" the crowd asked.

"What is chemistry used for? Chemistry is used to analyze matter, transform matter, extract matter. But you're still far from here, and I'm just here to take you on an outing. Ren Baqian said with a smile.

Then he asked Nagu, "Has this place never dried up?"

"I don't know. Nagu was a little confused, she didn't understand most of what these people said, but she felt that it seemed to be very powerful.

"Bring the rope. Ren Baqian shouted behind him, he wanted to test the depth of this black pool.

Soon, a stone the size of a human head was tied to one end of the rope and thrown down, causing a lot of splashes with a "poof".

There was no sign of life in this waterhole except for the stones going down.

"Your Excellency, stop. The guard lowered it five or six meters and the rope stopped.

"Find a branch, push the rope forward, try to land in the center, and test a few more places. After Ren Baqian gave the order, some students ran to find the branches.

Although Ren Baqian's words were not quite sure, the possibility of creating such a thing as salt made them all excited.

If it can be done, it will be a big deal.

Then the group tried again, and the deepest place was about ten meters.

After calculating these, Ren Baqian wrote them down, and then wanted to go to the mountain stream with light brown water.

"In the direction they went, it would take a day to walk, and it would take us at least a day and a half to get there. Nagu said.

Ren Baqian calculated the time, and it seemed that he had to go back to Earth first, and then go there.

Immediately everyone walked back, and when they heard the sound of some small beasts on the way, the guards rushed to look for it, after all, mosquito legs are also meat, and there is not much food in the village, so it would be best to solve some problems by yourself.

When I returned to the stockade, I arranged for eight thousand, and tomorrow half of all the guards built houses, and half went out hunting.

At night, Ren Baqian woke up Lin Qiaole: "I'm going to rub the hearthstone, don't you see?"

Ren Baqian felt that she had to tell Lin Qiaole anyway, otherwise when she woke up and found that she was gone, she would have to go crazy. This girl is stupid, but sometimes she is quite realistic.

"What is Hearthstone?" Lin Qiaole held his eyes with a confused expression.

Ren Baqian: "......"

"I'm going to leave for a while anyway, maybe a day, you don't have to worry. Ren Baqian said hello.

"No, Your Majesty asked me to protect you. Lin Qiaole finally came to his senses.

"The place I'm going to is a state secret, Your Majesty knows it, you just have to wait here. Ren Baqian waved his hand, paced to a corner of the room with a bottle of water from the black pool, thinking about going back, and the whole person disappeared in an instant.

The moment he disappeared, Lin Qiaole felt a trace of fluctuation in the air, and his eyes burst with fine light, like a lioness rushing towards Ren Baqian, but he pounced in the air, and all he grabbed in his hand was air.

"Huh——!" Lin Qiaole was slightly surprised, and reached out again to grab two handfuls in the air, but there was still nothing.

"What about people? Your Majesty also asked me to protect him, if he died somewhere else, he shouldn't blame me, right?Hmm-he didn't give me the candy he owed me yet......" Lin Qiaole muttered a few words, sat down against the wall, and stared at the place where Ren Baqian disappeared, but his eyelids couldn't open within a few minutes.

When Ren Baqian returned to Earth, he first contacted Yang Sen to arrange a laboratory, and he rushed to the magic capital with a bottle.

Anyway, if you are looking for someone else, they will also know, so it is better to let them test it, and you will save yourself trouble.

Seeing that Ren Baqian brought a bottle of water, Yang Sen was also excited, and when the test results came out half a day later, Yang Sen said with a surprised face: "This is brine?"

"What's in it?" Ren Baqian asked, and Yang Sen handed him the result directly.

Ren Baqian's eyes swept upward, and he only saw a bunch of NA, K, CA, MG, LI, BR, I, CL-, SO(2-) 4, CO3-, B2O3, HCO3 and the like, most of which he couldn't remember what they were.

It is estimated that the coffin board of his chemistry teacher will be unable to hold it down again.

"What are these?" Ren Baqian decided to ask shamelessly.

Janssen: ......

"Here's a researcher and explain it to Mr. Ren. Janssen connected directly to the internal phone. Ren Baqian asked him, who did he ask?

Fang Cai was still asked by someone from the research room.

Not long after, a young man with glasses with a cold face came up and gave the two of them a good lesson.

The final conclusion is that this is the ingredient of black brine, there is nothing unusual about it, and it is a waste of their time to take this kind of thing to the laboratory.

"Nothing else in it?" Ren Baqian is a little strange, but it is also a product of another world, so it will be a little different, right? Even if the soil I took before still has many microorganisms that are not found on the earth.

"Although there are some, they are not of much value, and those microorganisms can only give us a little more understanding of the ecology of the target world. The composition of the other parts is not much different from that of the black brine, which is not in line with previous expectations. To put it simply, this is the black brine of another world. The young man pushed his glasses.

Ren Baqian secretly gave a thumbs up after he left, he was the truth, and he deserved to be a person from the research room.

It's really different from a half-person like himself.

Ren Baqian laughed, not minding. After all, not everything from another world is useful.

"How are you practicing?" Ren Baqian asked curiously, he wanted to know how the basic exercises he had taken out were progressing so far.

"It's been too short a time to see much success. Yang Sen said simply, there is nothing to hide about this.

Ren Baqian nodded, it seems that the content in the early stage is basically like this. At the very least, you have to reach the human wheel level and turn your blood qi into essence qi before you can get some of the things you want.

"It's worth noting that in the level of transforming blood qi into essence qi, many people are stuck in front of this threshold. Ren Baqian reminded.

"We've noticed this too, and although each book is vague, we've found it in four books. Why don't you explain to us what we need to pay attention to here, and what is the focus of each stage?" Yang Sen proposed.

Ren Baqian spread his hands: "This can't help you." My exercises are different from these, and I don't know much about them. ”

"Oh?" Yang Sen's eyes lit up, and he heard something from Ren Baqian's words.

"In other words, there are many ways to practice the exercises?"

"Sort of, but there are some people who need a certain group of people to practice, and the one I brought is the most suitable for you. Ren Baqian thought for a moment, nodded and said.

The ancient tribe is different from that of Great Xia.

And there are also some differences between the "Ruyi Guan" that Ren Baqian learned and the exercises of Great Xia, if it weren't for this, he wouldn't be able to practice.

Yang Sen nodded, and did not propose to use the exercises to give them such a reference.

After all, these four exercises are already of infinite value to the earth.

If you are too greedy, it is easy to make the other party disgusted, especially if you haven't found out what the other party needs, and the other party is not a person who can selflessly dedicate in the name of righteousness.

Only when the cooperation between the two sides goes further can we find an opportunity to make a request.

Ren Baqian left the laboratory, and before returning to S City, he asked Shen Feng to prepare the information for boiling salt in black brine.

Now that he already knows the composition of the black brine, he is relieved, there are no expected twists and turns, and it is very plain and bland.

Although I was slightly disappointed, I have to say that this is the best result.

He had already checked some information before, even if he only used black brine, he could boil out the salt, but it would take some more time.

After a long period of tempering, the substances with sulfate in the water can be turned into monomer crystals, and then these substances are dissolved in the water by splashing water. Whereas, salt stays because it dissolves water more slowly.

Ren Baqian can imagine how much of a sensation it will cause when this news is transmitted back to the DPRK.

No matter how much manpower and material resources are used, Dayao will not let go of this opportunity.

Keep the salt in the palm of your hand.

You can also go back and prepare the historical record that reads, "Ren Baqian, a great pioneer, scientist, and educator, led twenty-four idle disciples to study the production method of well salt in Jiuding Mountain, and solved the problem of salt shortage since the founding of the People's Republic of China."

The only regret is that the solution is too simple, there are no twists and turns, and the writing is also plain and unattractive, not attractive enough, and it does not show that I have experienced 9981 difficulties and finally obtained the thrilling and touching method of salt production.

Think about it, the seven gourd babies go to the castle to defeat Snow White and her seven saints to rescue the little match girl, and the experience along the way is enough to write a heart-wrenching long story.

In the other case, the Lich King slapped the match girl and Snow White to death at the castle, and took the seven dwarfs back to live a life without shame. Which is more appealing?

So......

Ren Baqian felt that since there was no difficulty, he would create difficulties by himself. Mobile phone users should browse and read for a better reading experience.
