The place where the Huangqiu tribe is located is the sunny side of the mountain wall, and it will be exposed to the sun in the morning and afternoon, so if Shen Nong wants to dry the anise, he doesn't have to go out of his way to find a strong light source, just put it directly on a piece of bluestone outside the cave to receive the sunlight.

Many people were puzzled by Shen Nong's behavior, because they didn't know what Shen Nong was doing with such a lot of effort to fiddle with some plants they had never seen before, and this kind of fruit with eight horns didn't look like it could be eaten.

However, Shen Nong didn't mean to explain to them, seasoning spices can only make people feel their charm when they are added to food, and when this batch of star anise is sun-dried, Shen Nong puts them together with meat and bones to cook soup, and the people will know what is called fragrant.

"It's a pity that there is still no salt, if only our tribe could make their own salt, so that we don't have to worry about not having salt in the future. Shen Nong said with some regret.

Since accepting his identity as a witch in the Huangqiu tribe, he really wants to make the Huangqiu tribe continue to become stronger, this strength is not the provision of some tools, nor the expansion of more edible food, but hopes that the Huangqiu tribe will not be restricted by others in anything.

For example, the Tushan tribe will regularly bring salt to trade food every month, because their tribe has salt, so those tribes who want salt have to be restricted by them, and how many people's food can be exchanged for how many handfuls of salt each time, these must be decided by the other party, and the tribe being traded can only compromise for salt, and have no choice but to exchange a large amount of food for a small amount of salt.

The Tushan tribe's restrictions on other tribes are far more than that, any tribe that offends them, even if they take out more food, they can't exchange it for salt, and over time, other tribes will tear up their relationship with this tribe because they are afraid of being targeted by the Tushan tribe, so that they will fall into an embattled situation.

If Shen Nong could let the Huangqiu tribe have salt, this situation would be much better, at least the tribesmen would not have to spend a lot of food in exchange for a small amount of salt every month.

But this kind of thing is not so easy to do, first of all, because Shen Nong is in a primitive era, the relationship between scientific and technological conditions is limited, and he can't do some modern salt making methods, if you want to make salt in this era, you can only use the soil method.

The methods of salt making soil known to Shen Nong are: seawater boiling salt, salt lake salt mining, rock salt mining, and finding overflowing salt springs and soil salt, separating the brine with high salt content, and then evaporating the water through cooking to finally obtain qualified salt grains.

First of all, the location of the Huangqiu tribe should be inland, very far from the sea, and there is no chance of contact with sea water at all.

The only source of water near the second Huangqiu tribe is Baize, but Baize is a freshwater lake, and its water cannot naturally produce salt grains.

Therefore, if Shen Nong wants to make salt from the soil, he can only hope that one day he will be lucky enough to find an underground salt lake or saline-alkali land, but this kind of thing is no less difficult than discovering an iron mine.

The pecking bone standing behind Shen Nong heard his voice and said with some hesitation: "Wu, there is still salt, but no one likes to use that kind of salt." ”

"What did you say?" Shen Nong was shocked, and quickly turned around and asked, "Where is the salt?"

"On the hillside over there, the salt is stuck to the dirt, and the amount is still very small, and it tastes like sand. Peck said honestly.

"Earth Salt ......" Shen Nong's eyes rolled: "Take me to see." ”

......

The slope of the mountain mentioned by the pecking bone is a low mountain three hundred steps away from the south of the Huangqiu tribe, this low mountain is empty of grass, and it is a bald mountain that looks like it is not slipping away from a distance!

Shen Nong followed the peck all the way to the shady slope of this mountain, and immediately saw the soil mixed with white particles on the ground, which was one by one in the east and one in the west, as if it had snowed.

"Is there really one?" Shen Nong couldn't help but be happy, he really wanted to come to something, it turned out that there was such a saline-alkali land near the Huangqiu tribe.

"Peck bones, aren't these white ones all raw salt? Why don't you collect them and bring them back to the tribe for sifting, so that you don't have to exchange salt with the Tushan tribe in the future." Shen Nong asked, grabbing a handful of dirt mixed with white particles from the ground.

"I can't sift it off, the salt is completely stuck with the soil, and it tastes like an earthy smell, and many people would rather exchange salt from the Tushan tribe than eat this kind of soil salt. Bone pecking said.

The area of this saline-alkali land that Shen Nong stepped on is not very large, it is estimated that it is only seven or eight square meters, and it stands to reason that if this is really saline-alkali land, it is impossible to only have such a sprawling area.

Stepping on some soft soil under his feet, Shen Nong suddenly thought of something, and hurriedly squatted down and began to pick up the soil, only to see that he kept turning the soil with his hands, and soon excavated a basin-sized soil pit, the soil in the pit was softer, and it was a little moist when he started it, as if he had been watered.

"Wu, what are you doing here? These soil salts are useless, and the people in our tribe really won't eat them. Peck said helplessly.

Shen Nong glanced at him speechlessly, mdzz, I seem to be willing to dig for you to eat, if it weren't for the fact that there is an underground salt pond under this land, would Ben Wu do such an imageless thing?

"What nonsense, hurry up and help me dig the soil, you enjoy standing next to me and watching me work, don't you?" Shen Nong stood up and crossed his waist and said.

At the same time, he couldn't help but think in his heart: "I didn't expect that this digging is still a hard work, but it will exhaust me, and I will cross my waist first." ”

"Oooh. Hearing Shen Nong's order, Peck Bone also felt that his behavior at this time was a little inappropriate, and hurriedly squatted to the position where Shen Nong was originally squatting, and dug up the soil instead of him.

The so-called underground salt pond is some saline groundwater hidden in the ground, which is full of salt, which has the same effect as seawater, if it can be used for sun exposure, evaporate the water in it, and the salt can still be harvested after natural precipitation.

Shen Nong's eyes were firmly fixed on the place where the bones were pecked and digging, he was expecting, he was waiting, if there was really an underground salt pond underground, then the Huangqiu tribe would be gone, not only would they not have to take out food in exchange for other people's salt in the future, but they could also use their own dried salt to exchange food with people from other tribes, which can be described as killing two birds with one stone.
