After a closer look, it seems that the eighteen members of the deer tribe hunting team visited by the snake tribe, their appearance is similar to their leader, the most important thing is that they all have short hair, it should be too troublesome to have long hair, so they cut off their hair.

At this time, there is no "body hair and skin, the parents who receive it, dare not destroy it, filial piety to the beginning", and leave hair at will.

The people of the deer tribe like to keep their hair, basically the shortest hair is a shawl, and there are many waist-length ones, and there are no longer them, and anyone with too long hair will feel troublesome, basically the hair of the tribe is a little longer, and it will be tied with a rope.

Zhi and Yuan walked around the snake tribe's residence, and Yuan's men followed them and looked around.

The snake tribe Zhongyuan cares most about the two things of houses and pottery, and Tomoya carefully introduces these two things to Yuan.

From Chi's introduction, Nakain learned that the people of the snake tribe mainly lived in caves, but as the number of people increased, the caves became crowded, so houses were built to live in people.

Looking at the houses of the snake tribe, Yuan thought of the houses made of branches, leaves, and weeds where his people live now, the gap between the two is too big, the houses of the snake tribe can be protected from rain and can live in them, while the broken houses of the deer tribe can not be completely rainproof, and they are not warm in winter, and several children and even adults were frozen to death last winter.

"It would be nice if the deer tribe had such a sturdy house." Such an idea came to my mind.

There are also pottery, Yuan can roughly guess the role of pottery by looking at the appearance of pottery, they are good things to hold water, and only some stone basins and stone bowls can be used to hold water in the deer tribe, and the water contained in all stone basins and stone bowls is not as good as the water capacity of that large stone tool.

Yuan wanted the deer tribe to have that kind of sturdy house, and also wanted to get this kind of pottery that could hold a lot of water, but Yuan couldn't open his mouth to ask his good friend for the pottery and the construction method of the house, and the snake tribe gave the help to the deer tribe during several hunts, and Yuan had not had a chance to repay it.

Su Yan saw Yuan's thirst for houses and pottery from Yuan's gaze, pottery is okay, the house will be troublesome, if there is no Su Yan to teach it, a tribe wants to build a house, can only slowly grope forward step by step, and may not be able to build the house that appears in the snake tribe for decades.

The pottery is simpler, and the pottery firing technique is not taught, and the pottery firing technique is also very difficult to learn, but the pottery is small in size, so it is good to take it directly.

Thinking of this, Su Yan said to Zhi: "The leader (colloquial), tell him that he can exchange things that are not in the tribe for pottery. ”

"Okay." Zhi agreed.

Then Zhi and Yuan communicated with gestures, telling Yuan that they could exchange things for the pottery of the Snake Tribe.

Knowing that he could exchange it for pottery, Yuan was pleasantly surprised, but then he hesitated, he didn't know what to exchange for pottery.

In this era, the most important thing for primitive people is food, but the food needs of the deer tribe cannot be satisfied, so how can they exchange food for pottery from the snake tribe.

Again, if the Deer Tribe can take out something that the Snake Tribe does not have but is useful to the Snake Tribe, it can also be exchanged for pottery.

Yuan thought about it carefully, but he couldn't think of a thing in his mind that could be exchanged for pottery.

Suddenly, Yuan patted his head with his hand, looking like he had figured it out.

I saw Yuan take a package of animal skin that was no more than the size of an adult's palm from the straw rope around his waist, and Yuan opened the package, revealing what was wrapped in the animal skin, a kind of brown crystals mixed with earth.

Yuan made a few gestures to Zhi, motioning for Zhi to learn from him, and Yuan lightly dipped his right index finger in the crystal, and then put it in his mouth and sipped it.

Zhiya learned the action of the edge and dipped a little crystal into his mouth, and as soon as he put it in his mouth, he spit it out a few mouthfuls, and quickly scooped water with a pottery bowl to drink, and then returned to the edge after the taste in his mouth was expelled.

Zhi looked at Yuan angrily, and kept gesturing with his hands, which roughly meant that this thing was poisonous and could not be eaten.

Yuan quickly shook his head, and then gestured with his hand and said that this thing is a good thing, and eating it can give us strength.

Faced with the explanation of the fate, Zhi was a little puzzled.

Next to Zhihe Yuan, Su Yan witnessed what happened and roughly understood what was going on, and Su Yan had a bold guess in his heart - the crystals contained in Yuan's package were salt!

Salt is very important to people, although humans only eat a lot of salt after entering the agricultural era, but now the value of salt to the snake tribe is also very high, for example, the salty taste of salt can be used as a seasoning, and the food pickled with salt can be left for a longer time, and eating salt can also maintain people's physical strength.

The people of the snake tribe rely on eating animal meat, fish and drinking animal blood to replenish salt, which can maintain people's daily activities, but they can't do strenuous activities all the time, and they will be tired very quickly if they do strenuous activities all the time, and they need to take a break to slow down.

If you consume a certain amount of salt every day, you will not get tired so quickly after doing strenuous activities.

Still unable to determine whether the crystal was salt or not, Su Yan decided to try it himself.

"Chief, I'm going to eat that."

"No, that thing is poisonous, you can't eat it." Zhi disagreed with Su Yan's risk.

"No, I'm going to eat it, there's a good chance it's the salt God made us seek."

Well, Su Yan used God as an excuse, Zhi could no longer stop it, Su Yan asked Zhi to look for salt last year, but Zhi and the rest of the clan couldn't understand such a thing as "salt", and in the end it didn't work.

Su Yan gently dipped a little crystal with his hand and put it in his mouth, and the next moment he spit it out, Zhi handed over a bowl of water at the right time, Su Yan rinsed his mouth with water, and finally drove away the odor in his mouth.

After Su Yan's personal verification, this brown crystal is indeed salt, but there are too many impurities in this salt, salty taste and other unpleasant irritating tastes.

After confirming that the thing in Yuan's hand was salt, Su Yan said to Zhi: "It's salt, the tribe needs salt, and the leader exchanges it with him with pottery." ”

Chi nodded in understanding.

There are loyal and honest people among the primitive people, and there are also people with cunning personalities, and Zhi, as the leader of the snake tribe, has a high level of wisdom, and in the end he exchanged a relatively small pottery bowl for all the salt on his body from Yuan's hands.

It is not kind to outsiders, but in Su Yan's opinion, this is a normal thing, the value of pottery in the snake tribe is not high, the value of salt in the deer tribe is not high, the snake tribe needs salt, the deer tribe needs pottery, and the transaction between the two tribes can satisfy both parties.

Yuan wrapped the pottery bowl in animal skin and put it in his arms and carefully put it away, treating the pottery bowl as a treasure, and then Yuan and Zhi agreed that after a few days, Yuan would bring more salt to the snake tribe in exchange for pottery.

After staying in the snake tribe for a while, Yuan left the snake tribe with the deer tribe hunting team, their hunting task today has not been completed, maybe the people of the deer tribe will be hungry today, and they can only fill their hunger with salt water.
