After his previous visit to Youyan, he was inspired, and he remembered the picture of an elephant licking the salt stone, and recalled a lot of information about salt.

Carnivores don't need to lick salt, because there are trace amounts of salt in the blood of other animals, and people are born unable to resist the temptation of salt, and they have to eat salt to live, perhaps it is so, so primitive warriors will drink animal blood raw when hunting.

At the beginning, his Matsu said that the warriors would gain strength by drinking blood, which may also be because there is salt in the blood, and people can only maintain their strength by eating salt. Under normal circumstances, each person can ensure physical strength by consuming two grams of salt per day, but in fact, it will exceed several times, or even more than ten times.

In turn, as a hunted herbivore, it is the nature of animals to obtain trace amounts of salt from plants through forage, or through soil, stones, and salty water containing salt.

When Su Yang was observing the environment around Youyan, he found traces of being licked, which should have been left by animals.

Therefore, he specially explained to Chun, and asked the soldiers to come back and report if they found animals licking dirt and stones when they were tracking their prey. In particular, pay attention to the three types of animals: cattle, sheep and deer.

I didn't think that it would only take two days to make a discovery, which made Su Yang very excited, and with his own salt mine, he had the foundation to open a bazaar.

However, finding a place with salt, this is only the first step, how to mine is the most difficult, a well salt in later generations, often requires many households to contribute, spend a year or two, or even more time to complete the preliminary work, so the choice of mining site is also critical.

He planned to identify a few more places with salt, and finally choose a more suitable location for the establishment of the tribe, yes, he planned to relocate the rock tribe from this pimple corner, looking at modern towns, the location is really important, at least there must be resources, relying on the mountains and the water to draft the water.

With this in mind, he followed the warrior out of the tribe, and there were two warriors waiting to meet him outside, and after the convergence, the four of them hurried to their destination, which was unsurprisingly within the range of the Chaos Tribe, and also in the direction of the area close to the savages.

When he was about to arrive, the warrior pointed to his feet and said, "This is the mark that the prey has walked on." ”

Su Yang looked down and didn't see anything. Although he is a veterinarian, it is for livestock in the farm or pen, and his wild hunting ability is still in its infancy, so he is not ashamed to ask, "How do you see it?" ”

"Footprints!" The warrior lay on the ground, pointed to some marks, and twisted the dirt and put it between his nose to sniff.

Su Yang followed and learned, but in the end he still seemed to understand whether he understood or not, could it be that his thinking was solidified, and the older he was in his mental age, the more he could learn new things, but his ability to learn new things decreased? Just like WeChat, which elementary school students can play, you may not be able to learn it if you let a retired old professor.

I didn't bother with this problem anymore, and continued to hurry, and it didn't take long to see spring, and the person who led the team of the chaotic tribe was a merchant girl, and the team configuration that went out last time was strikingly similar.

"It's just ahead." The merchant girl ran over and said hello.

Su Yang nodded, at this time he thought of more, he wanted to annex the Chaos tribe and let the Chaos join the Rock Tribe as the Jiuli clan, anyway, after the Chaos tribe was a sinner, there was no original totem, and there was no way to return to Jiuli at all.

He can support Jiang Li to ascend to the throne and become the sixth elder of the Rock Tribe, and at the same time, Jiang Li will also become one of his opponents in the future.

But the benefits are also obvious, the Rock Tribe will grow rapidly, the territory will more than double, and the resources will become richer, compared to the area of the Rock Tribe, the location of the Chaos Tribe is better, flatter, and bordering several tribes, and he can consider pulling the Sky Wolf Tribe in the next step.

In a flash of thought, when he arrived at the place, there was a small hill in front of him, there were many plants on it, but there were not many trees, and when he arrived here, he could see the traces of animals coming often, and there was a lot of feces on the ground, and the smell was very strong.

The slope is also full of potholes, very similar to the outside of the mountain where the Yan clan is located, and immediately Su Yang stepped forward, grabbed a handful of soil from a pothole, and put it into the bamboo tube he carried with him, there was clear water in it, and after mixing the soil, it instantly became turbid.

He summoned three more honest and obedient warriors and asked them to take a sip each, originally hoping that the three of them would taste whether there was salt or not, but they only tasted earthy. In the end, he took a small sip of his own and vomited directly.

"Take a piece of wood and burn it."

This is the method of using soil, charcoal fire scraping salt, and so on to burn the sticks into charcoal, then pour mud water on it, and finally let him discover black salt, of course, the salt content in the soil is very low, far inferior to brine, and there is no way to extract the salt in the soil, there are too many impurities.

"Su Yang, you're burning salt!" The merchant girl was stunned, she had never thought that there would be salt in the soil.

Well, the time to brush up on prestige has come again, Su Yang called two warriors to lift him up, barely climbed the height, and said loudly: "We people need to eat salt to have strength, and prey also need to eat salt, but the prey has no salt, so they go to lick the soil with salt, and there is brine in this soil, which is the kind of salt water that was exchanged from the salt clan before." Did you all get it? ”

He said so much, but few people understood, and the merchant girl understood what he meant, staring at the small hillside with her eyes shining.

Su Yang smiled, and immediately led everyone to explore the small hillside to determine whether there was value in mining, every salt mine needs to be filled with manpower, so the decision is very important. Luck is also very important, and if you find that there is not much brine in it after mining, it will be a tragedy.

An hour later, he crouched in front of a spring, his eyes full of incredulity. The spring is small, less than a square meter in size, and the water that flows out of the cracks in the stone is small, but the water is salty. Although the salt content is not as good as the brine with salt, this spring water can also be used to boil salt.

"Brother, this is going to be sent!" Su Yang thought of the several salt grabbing turmoil in later generations, and a bag of salt could be sold for thirty-six yuan for one yuan, and he couldn't buy it if he wanted to. And in the current period, the value of salt is a huge profit, not to mention only thirty-six.

Five catties of salt can please a daughter-in-law, two catties of salt can recruit a son-in-law, and the value of a person can be measured by salt. Unexpectedly, the first time he shot, he could find such a spring, more dare not say, it is not a problem to collect dozens of catties of salt water a day, if it is summer, it can be more.

Even if the salt content in the water is only five percent, it is conservatively estimated that it is absolutely no problem to produce two catties of salt a day. And because it has less salt, it can shorten the boiling time.

What's more, it's just a natural spring, so how much salt can there be in this hillside in front of you? How rich is the salt just below the hillside? That picture is so beautiful, I dare not think about it!

With this luck, he wants to change his name to Su Aotian!

Unfortunately, this place is not suitable for the establishment of tribes, because the four sides are ventilated and the slopes are not high, so it is impossible to build the tribes on the slopes, so if you want to defend this place, you must use large works to cut down and clear out large areas of woods. Ponds are also dug to stock up on drinking water, and perimeter walls are needed to prevent wild beasts from attacking.

If you want to plant, you have to open up the wasteland, and just cleaning the roots of the trees will be extremely cumbersome and waste a lot of manpower and material resources. In addition, it is necessary to guard against the attacks of the wildlings. If you want to open a market here, you will have to build roads to ensure the safety of other tribes coming here.

These are not the only things, the most important thing is how to adapt the people to this unsafe environment.

But in the face of such a rich salt land, Su Yang felt that he could do it!
