Along the way, I hurried and hurried, and finally it took me five days to return to the tribe.

Back in the tribe, everyone relaxed a lot, and this year's task is basically completed, and then hunting, fishing, wandering around, and waiting for winter to come.

Although it hasn't snowed yet, the temperature is already very low, and many animals are dormant, so most of the work is still a pastime.

"Oracle, gone?"

Looking at the two canoes with not much things, Shi Yu was a little stunned, after all, he loaded a few boats and came back last time, but this time it turned out to be almost the same as the things he took away, wouldn't it be lonely to run back and forth this time.

However, seeing that the package was full of seeds, he reacted, and his feelings were to exchange things for seeds, and until now, most of the people in the tribe have not realized the importance of rice, but because of what Song Xuan made, even if there were some superfluous thoughts in his heart, they never showed it.

"Oracle!"

There are still a lot of tribesmen in late autumn, so it is very lively, and when Song Xuan comes back, they also greet each other.

A few days of rushing made Song Xuan a little tired, so he asked everyone to divide the seeds, and let them carry the stones to their own rooms, and when they had a good rest tomorrow, they would see if there was anything worth using in the rest.

Although everyone still doesn't know the wonderful use of rice seeds, they are not completely unaware of Song Xuan's thoughts, just like the hemp in it, it is very useful in the tribe, and it is used to replace the original animal skin in many places, and the effect is quite good, especially in some relatively sophisticated weapons.

So many seeds add up to only 100 catties, and everyone separates them together, and the speed is still very fast.

The seeds of different tribes are packed in different clay pots, but fortunately, except for rice seeds, the number of other seeds is not very large, and it is generally two or three.

This also saves the need for a small jar for each seed, and although there are many jars and jars in the tribe, it is not so wasteful.

As for whether there is anything useful in it, we can only wait until next year to grow.

The next day, Song Xuan, who finally had a good night's sleep, got up early in the morning, now the weather is colder, even in this primitive society, everyone will not get up too early, there must be no warmth outside the house.

Especially now, most of the houses have a larger clay pot, this is a simple brazier, because the whole wall and roof are pasted with thick grass and mud, so the warmth effect is also good, and after the house is warmed up, it does not use much firewood, the effect is very good.

Once used, everyone quickly fell in love with this gadget, in this way, at least it is much more convenient to clean, after burning, the ashes will naturally fall at the bottom of the basin, pour it every few days, and it can move away, although the previous heating is also a fire, but it is in a fixed place, generally in the middle of the house, although the effect is not bad, but after all, there is no such convenience.

Shi Meng did not go out to hunt, but rowed a small boat to go downstream to fish, this way back, saw too many big fish, which also made them a little itchy, instead of fighting with wild beasts in the mountains, it is better to take a net to get a few big fish.

Winter fishing is naturally not as convenient as summer, the current river water is too cold, unless it is a last resort, it is generally not easy to go into the water, so the fishing net has also changed from the previous direct water arrangement, into the current boat lane, although the efficiency will be slower, and it is easy for the fish to take advantage of the loophole, but it is still a little better than going into the water.

And after several generations of improvement, the current fishing net has been very long, a fishing net is seven or eight meters long, three or four meters wide, as long as the place is well chosen, even if you don't need to combine the array, you can catch some fish.

However, after so many times of fishing around the tribe, there are not many big fish, but since they are interested, Song Xuan is still very supportive, no matter what they do now, as long as there is a harvest, it is very good, looking at the weather, at most it is more than half a month, the heavy snow should be about to fall, it is rare to have a time for everyone to do what they want to do, just let everyone be happy.

He returned to the house, and began to jingle and knock on the stones again, this time the harvest was a little better than on the ship, just like the red stone in his hand at this time, Song Xuan always felt that it seemed to be a little similar to iron ore, but after all, it was still too different from the pictures he had seen before, but it vaguely felt like it, and the feeling after smashing it was not the same as other stones, the ingredients in it must have their own special features, but if it is not metal, I don't know.

Even so, this is a big breakthrough, the hope of this stone is always so great than the others, and even if this is not, when the ore is collected in the future, you can also let everyone follow this standard, don't stuff all the garbage like this time.

Song Xuan didn't understand it very well for the first time, and the surrounding tribes also wanted to pick up stones to exchange for pottery, so they weren't very careful, so naturally they couldn't be so lenient in the future, if they didn't have any requirements, Teng Snake would still lose a little.

Since they want to exchange things from Teng Snake to go back, they naturally have to pay something, and the things that Man Dashan picked up casually can't deal with, but after this transaction, it is not so easy for them to get stones that are easier to find in the future.

"Huh~"

Song Xuan didn't expect that he had just discovered a stone that might be useful, but this time he made a new discovery, the pure white stone in his hand didn't even need to be knocked by himself, and there were some places where he could crush it with a little force.

And after touching it, the hands were also glued with gray-white powder, in Song Xuan's cognition, there didn't seem to be many things that matched this kind of ore, and the most commonly used was lime.

And the way to identify whether it is lime or not is also very simple, just throw it directly into the water, so Song Xuan hurriedly brought a basin of clean water.

From the corner that was the easiest to break, he got a little bit and threw it into the water, and sure enough, as soon as he threw it down, the basin gurgled and bubbled, Song Xuan carefully tried it around, the originally cold water was already a little warm at this time, but because the amount put in it was not much, the feeling was not too strong.

But even then, it should not be a problem to be sure that this ore is lime.

Although it is not a metal ore, but the role of lime is also a lot, Song Xuan alone knows that there are several, among which the most used is naturally used in buildings, if Song Xuan remembers well, the ancient famous Sanhe soil should also be mixed with lime.

It just so happens that there is a lack of binders between bricks in the tribe, and the clay can only be used to make it unsatisfactory, although it can be used but the effect is not much, and it is still like a solid kiln after burning it for a few days, but if you don't do anything, there are still obvious cracks after drying.

As for cement or something, Song Xuanke never thought about it, although he knew that there was such a thing, but from the raw materials to the production process, he didn't know it at all.

If the tribe can make a triple soil, it will definitely be a great help for building a house in the future, and the strength of the wall glued with soil is still much worse.

After all, Sanhe soil is something that has been tested by history, and so many buildings in ancient times can still be used after thousands of years or can still show its solidity.

Among them, lime is a little harder to find, and other clay and sand are more or less around the tribe.

Song Xuan also only hopes that no matter whether it is big or small, this is best a lime mine, and the population in the tribe is not large, as long as it is not too small, this stone is still found from the stone they got from the Kite tribe, and the relationship between Teng Snake and them is not bad, as two relatively powerful tribes in the tribe, there is no contradiction between the two sides, and Teng Snake also exchanged a lot of pottery for Iris Rain.

And the kite tribe is not very far from the Teng snake, about six or seven days away, the kite tribe is also the upstream of another river, the position is higher than the Teng snake, if it is really limestone, it will not be too troublesome to transport it later, most of the distance can go straight downstream.

Just when Song Xuan was thinking about the future construction of the tribe, Shuiyun who went to the sheep tribe had indeed returned, what Song Xuan didn't expect was that this round trip would take three or four days, and these people would only come back one day later than him.

"Oracle, Oracle, we're back!"

As soon as Shui Yun came back, he went straight to Song Xuan, Song Xuan also put down the work in his hand and quickly went out to meet him, after all, it was the task he arranged for them, and Song Xuan also knew what happened to the sheep tribe.

"Shui Yun, what happened to the sheep tribe?"

"No, it's not a big deal, it's just that I haven't eaten!"

There is nothing to eat, it is not a big deal, and Song Xuan is also a little stimulated by Shui Yun's brain circuit.

"Then why don't you come to the exchange conference for some food?"

Shui Yun hurriedly shook his head and explained:

"Look at them like that, there should be nothing to change, the last heavy rain washed away their food and fur, and they were still hunting outside for a few days when we exchanged!"

Although the damage of the sheep tribe is smaller than that of Shuiyun, it only saved the cave, and how much water can wash the cave away.

So after a big flood, it was basically poor and white, only some food was temporarily rescued, barely survived the rainy season, and after a few months of hunting, it was very difficult to save enough food in the next half year, so Yangyang They have been running around on the way to get food.

So much so that they even missed the exchange meeting, and it wasn't until Shui Yun went again that they remembered that there was such a thing, but even if they participated, it was useless, they could barely use the animal skins for their own tribe, let alone exchange things for food.
