This simple operation taught to them by Lin Su has been learned by many people. Even some children were pleasantly surprised to find that they could catch fish with their baskets.

So everyone cherishes the basket even more.

I didn't expect a box to do so much.

And some of the bamboo left over from the frame Lin Su also asked them not to throw it away, and they could be made into drinking cups. Although everyone felt that it was unnecessary, Lin Su still strongly asked everyone to have one, so that they should try not to drink raw water and drink more boiling water.

And also let the two girls boil hot water, as long as everyone wants to drink, they must only drink hot water. The reason why everyone listened to Lin Su was based on the fact that Lin Su had created a lot of value, and everyone also found that what Lin Su said had made them gain a lot of benefits, so they finally agreed.

This is still the first step, the second step, Lin Su is going to wait for the winter to dig a thatched pit with everyone, otherwise all the food and drink will be in the cave in the winter, and the six months will be too difficult!

And it was very easy to get sick in this way, anyway, under Lin Su's persuasion, most of the people in the tribe began to drink hot water. Especially for children, Lin Su strongly asked them not to drink raw water.

For this reason, I also thought about it and made a bamboo tube water cup that can be covered with a lid. This water cup was once again liked by everyone in the tribe, and it didn't take long for everyone to have one. Every day when the young people go out hunting, they each carry a larger bamboo cup, which is tied up with discarded cow tendon and carried on their backs, and even some women like to have a bamboo cup on their backs, and the cup that used to drink water is left in their tents.

Especially children, they will also compare the size of their bamboo cups.

Just as we were approaching the last week of winter, everyone was almost ready to prepare winter food. Meat is basically gone, so every day everyone brings back some fish and snow balls that Lin Su said can be eaten.

Fortunately, no one seems to know that this thing can be eaten in the primitive world, so it is still relatively abundant for the time being.

However, in the last few days, Lin Su found that both the old people and the young people of the tribe began to help compile memorization. After thinking about it carefully, Lin Su remembered that in the last week, the tribe would go somewhere to exchange salt, which was necessary for winter.

Before, they had traded for food, but this time they had made a lot of memorizations, and it was new, so they believed they could get something good.

There are old people and children in the tribe, and it is definitely best to be able to survive in winter. So no one wants to trade food out.

Half of the young people were going to exchange, so Lin Su also volunteered to go with him. After all, she is still a little skeptical about the IQ of primitive people, so she wants to follow along to see if she is trapped.

In the last few days, there were twenty people who set off, and each of them carried more than a dozen memora, all of which seemed to be of the best quality, but the small baskets had also increased a lot in the past two days.

Whoever has a tribe has children, and this thing can barely be used.

However, Lin Su picked a lot of larger leaves on the road, and although everyone didn't understand what Lin Su was going to do, they helped pick a lot.

After walking for nearly two days, I walked to the so-called exchange venue. It's also by the river, but it's a two-day walk, so you can see how far it is. Or because they are all a group of young people and have better physical strength.

"We were all exchanged with the Haiyan tribe. Chan said next to Lin Su.

Lin Su: Sure enough, it's a tribe that knows what it is when you hear the name!

The Haiyan tribe has mastered the method of making salt, so among the tribes, the status of the Haiyan tribe is also relatively high. At the same time, the Haiyan tribe has a large population, so every year before winter, they also refer to this exchange, which can be exchanged for some more food, so that they can spend the winter.

In fact, the Haiyan tribe is the best of all the tribes, at least they have too few people starving to death in winter.

"Alas, Uncle Al, we have come in exchange for food. Seeing that Lin Su didn't seem to have the idea of being the leader, a few people together stepped forward to greet him according to the previous pattern and prepared to exchange for something.

"Hey, it's you! How much food did you bring this time?" comes every year, so everyone is familiar with it.

However, the people of the Haiyan tribe are generally high-minded, and this Uncle Al is also relatively kind, so every time they come, they basically ask Uncle Al in exchange.

"We've made some baskets that can hold things, and I don't know if we can trade them in. Uncle Al looked behind him, and saw that the back basket behind Can's eyes was about to win the prize.

Uncle Al's eyes lit up and he said, "Good thing!"

They get a lot of food every year, and a lot of it is not complete, it's basically the kind of piece by piece, so every time they move back, it gives them a headache. If you have these baskets, you can save a lot of time and effort.

"How many of you?

"Uncle Al, this basket can be used all the time, it is not easy to break, if you want it all, you may have to ......" The young man probably didn't know much about bargaining, and when he said this, he scratched his head, looking a little embarrassed.

"Hahahaha, good fellow, don't worry, Uncle Al will definitely not treat you badly this time. ”

Lin Su saw that his eyes were shining, although the coarse salt he gave this time did not treat them badly. But Lin Su guessed that these people were afraid that they would definitely study some of the production methods of this memorization when they went back, so I am afraid that they would not be able to exchange this next year.

In fact, although the memorization looks complicated, I really master that even children can compile it, but it is not so tight.

In exchange, Lin Su asked them to wrap it in large leaves, and then there was grass on the side of the road to tie it up, spread a few layers of leaves in the back grate, and put the bundled coarse salt into the back grate, which was not easy to sprinkle, and there was no need to wrap it with hand skin, which made everyone feel a lot easier.

Lin Su felt that if he still had time to go back, maybe he could ask them to make a mat or something.

"It's great that these backs can be exchanged for so much salt, and we will have enough until next summer. "Everybody has salt on their backs, which makes everyone feel very satisfied.

"We can still bring an exchange next year, and then we ......," Chan said ideally.

Lin Su shook his head and interrupted: "It's not that difficult to weave a memorization, if the Haiyan tribe goes back and takes it apart, it will be easy to learn." I can't bring this with me next year, so I'm going back and figuring out what they can't do. ”
