Wang Chuan's comfortable bed didn't sleep on his own for a night, and it has since become a gathering place for children. Pen? Interesting? Pavilion wWw. ｂiquge。 infoThey like Wang Chuan's clean and soft bed, and in fact, they prefer to gather around Wang Chuan after eating and listen to him talk about all kinds of new things. Sometimes, adults will listen quietly for a while.

I have just experienced the treatment of roundworms, of course, I want to tell them about what these worms are all about, and by the way, I want to emphasize the importance of hygiene and the dangers of roundworms.

This is certainly not an easy topic. In the past two days, the tribesmen have been pulling the insects for two days, and they are still suspicious, and they are using their only knowledge to explain this strange phenomenon. Now I know the truth, and I know that it is grown from those things that I eat. The adults were confused, they didn't understand how it grew, and the children were terrified, they didn't want to grow with this thing in their stomachs.

"Roaring fire, you said this is what everyone will grow?" The grandmother next to her asked.

Usually, my mother comes to see and goes back to sleep. Now that she is in high spirits, she will also sit next to watch Wang Chuan answer various questions from children and teach them to count or read. When she is in good spirits, she will also tell a little about what she has seen.

As an insightful person, she sees things from a different perspective than others. After Wang Chuan affirmed the answer, she then asked, "So, people from other tribes will also grow these things?" ”

"It should be."

Grandma said solemnly: "This kind of ...... Medicine, you can tell people from other tribes. But without my consent, it can't be drunk on their people. ”

As she spoke, her mother also focused on the bamboo tubes, and looked at the adults in the crowd. Wang Chuan saw it clearly, and his mother saw it as a coincidence.

Wang Chuan couldn't understand the details. But he could guess what his mother was thinking. That's what a technology monopoly means. In my mother's view, having these bugs in her stomach is undoubtedly like having a child in her belly and will eat more food, but these bugs are not children and will not grow into children. After taking this medicine and knocking them out now, it is obvious that you can save a lot of food in the future. This kind of thing that can save food must let others know, and it depends on the situation of getting along with the tribes or the exchange of interests in the future.

The benefits of medicine Wang Chuan understands better than his mother that in this topic, the focus that Wang Chuan wants to understand is this so-called "other tribes".

After human beings developed to the point where they could use fire, later studies pointed out that there were conservative estimates of 10 million people on the earth, and even more if they were not conservative.

The tribe's previous activities of "inviting the god of fire", interkinship, and exchanging salt all indicate that there were other tribes around. It's just that the primitive man's self-sufficient living habits make the communication between the tribes pitiful, and he has been wearing it for so long, and he has rarely heard of information from other tribes. Not a single outsider has ever seen it. And from the memories of the original body, there are almost no memories of outsiders.

He was interested to know how the people of the other tribes were doing. Knowing the situation of the surrounding tribes, we can see the current level of productivity, so as to infer the productivity of the current mainstream society or group of people in the north, and guess their current social composition. Wang Chuan always felt that in today's unsmooth exchange of social information, the imbalance in social development may be more serious than at any other time. When they were still drinking blood, the north might already be a dynastic society. If there was a dynastic society in the north, would he be able to live a better life as long as he took the tribesmen to the past?

"Mother, are there any other tribes around us?" Wang Chuan asked cautiously, lest he would make his mother unhappy.

Mother didn't know what Wang Chuan thought, she was still happy to answer his question, she thought about it, and said in her own language habits: "The mountain ridge of the big fallen tree goes north to the north, and there are potato chunks in that col, but there are dolphins there, and you have to avoid the big ones, that thing is too fierce...... After another day's walk, you will reach the dolphin department. I haven't seen them since the last time it snowed, and I don't know how they're doing......"

"Mother, this dolphin tribe, what kind of tribe are they?"

"Dolphins?" Maybe Wang Chuan's question was a bit broad, but the mother thought about it before saying in a concluding sentence: "The dolphin is good." They hunt dolphins, eat potatoes, eat vines, and live in burrows. There are intermarriages with us, and there are no things to be exchanged. There are more people than we do. ”

"Our fire and salt were exchanged for them?" Wang Chuan then asked.

Mother shook her head and said, "No, they are also the same as us, they want to go to the Vulcan Ministry." ”

"Where is the Vulcan Ministry?"

"Dolphin goes north again, over mountains and two rivers, and it takes three days to get there." When Mother talked about the Fire God Department, Wang Chuan could see that her expression was a little cold.

"How are they?"

"They are evil. Lots more people. There are arcs, do not exchange with us. Ask the god of fire to ask for meat on the backs of five people. Change the salt, and ask for meat on the back of one person. Relatives, to change people, tall for short, strong for thin, but also for two people to carry meat. Coincidentally, he came from the Vulcan Ministry. Fire boys, you must be careful in exchanging with them, and you can't lose. "My mother is speaking more and more badly, just like she used to say about wolves or elephants.

When my mother said meat, she meant meat and other foods. Back refers to the number of people who can carry it, which is about seventy or eighty pounds. In this era, there is nothing to measure, and you can only use the primitive algorithm of memorization.

In this era, interrelatives were generally exchanged between two tribes, and direct marriage was rare. Because the population of each tribe is limited, marrying off the adult labor force to your own tribe will have one less labor force. There is no problem with the direct exchange. In this way, the bloodline will not be chaotic, and the population of everyone will not change.

Qiao is the most capable woman in the tribe, she is ingenious and diligent, but she is not very tall. This shows that in terms of height, she was taken advantage of by the Vulcan Department when she came back. Second, it also shows that the mother did not lose when she exchanged her, because her ability can offset her height defect.

When the two tribes are compared, this shows the difference between the two tribes. In other words, this is the difference between a kind poor neighbor and a treacherous rich neighbor.

"Are there any other tribes?" Wang Chuan asked again.

Mother said: "There are still tribes in the east and west, but they only trade with the Vulcan Ministry and will not look for us. When my father was there, he also said that there were people on the other side of the river, but they were never seen again. ”

It seems that the influence of the Vulcan tribe is still quite large among the surrounding tribes. There are at least four or five tribes here that trade around them.

The tribes of the East and West must be far away, and they may not border the territory here, so it is possible that Ah Mu has not been in contact with them.

As for the situation of the tribe across the river, Wang Chuan felt that it might also be far away. The terrain on the opposite side was familiar to him in later generations, and although there would be changes now and in the future, there should be no such naturally formed caves in a large area on the opposite side, which he was sure of. Nowadays, the tribe is basically inhabited by caves, and if there are no caves and there is no trace for decades, it is unlikely that they will be nearby.

However, Wang Chuan noticed that even the poor neighbor dolphin tribe had a relatively fixed source of food, so their population was relatively large. Not to mention the Vulcan tribe that has the initiative to trade with several major tribes and the Vulcan tribe that also masters bows and arrows. They can get a lot of benefits by simply exchanging, and the use of bows and arrows allows them to get an abundance of prey, so they are more numerous.

It can be seen that having a fixed source of food and relatively sophisticated production technology is a more reliable way forward for development.

After talking about the simple situation of the surrounding tribes, Ah Mu briefly talked about the communication with the two neighbors.

In general, there was very little communication. Judging from the situation in previous years, it was only once a year. This exchange is usually carried out in the autumn, and the exchange of fire and salt, and kinship will be completed during this exchange.

But my mother said this, but she never mentioned this year's exchange. Now that there is a roaring fire boy in the tribe who can make a fire, she won't come to the door to suffer.

As for the matter of salt and interkinship. There is such a thing as salt fruit, and the tribe itself does not eat much salt, so there is no need to exchange it for the time being. There are a few young people in the tribe who have reached the age of marriage, but in Wang Chuan's opinion, these are still thirteen or fourteen-year-old children, and it will not be too late in two years. It is estimated that the mother also has the meaning of making them wait.
