Su Yan made a round in the residence, except for the problems he found when he just returned, he didn't find any other big problems, and some small problems found were not too important to the dragon tribe and could be ignored.

When he just returned, when he walked outside his residence, Su Yan suddenly discovered a very important matter, which Su Yan had also ignored before, and the other clansmen had not noticed this matter, but fortunately, Su Yan noticed this matter, otherwise this matter would make the Dragon Tribe pay a huge price in the future.

It's been more than a month since the dragon tribe moved to their new home, and the new home doesn't have a wall!

The fence can be made of adobe bricks, stone and clay, or a fence made of branches or rattan......

The most important function of the wall is to separate the tribe's habitat from the outside world, and when the beasts or other primitive tribes attack, there is a wall barrier, and the dragon tribe will have a very big advantage.

I still remember that when I was in my hometown, the dragon tribe was attacked by other primitive tribes twice, but because of the existence of the wall and the vigilance of the dragon tribe, the dragon tribe defeated the enemy without damage the first time, and the second time it paid a small price to annihilate the enemy.

And in the cold winter, the beasts are hungry and crazy because of the scarcity of prey, and even the primitive tribe dwellings that usually don't come over will come to hang around, and they will also try to attack the primitive tribe, if there is no barrier of the wall, the primitive tribe will be dangerous.

When the snake tribe was still there, because there was no wall, the people of the snake tribe hid in the cave for most of the winter, and they did not dare to go out at night.

This shows the importance of the wall, and the new home of the dragon tribe should also be built as soon as possible, even if the dragon tribe is strong now, it is necessary to be vigilant against the attack of beasts and other primitive tribes.

There are several types of walls, brick walls, stone walls, fences, and so on.

The brick wall is made of adobe bricks, and the brick wall is the strongest of the three types of walls, but it takes the longest to build;

The fence is made of twigs or rattan, and it takes the shortest time to build, but the fence is not very useful, and even the larger beasts cannot stop it;

The stone wall is made of stone and clay of different specifications, because the binder is clay instead of cement, and a heavy rain may collapse the stone wall, but in winter it has a good resistance to wild beasts or other primitive tribes.

Su Yan thought about it carefully, considered the advantages and disadvantages of building three kinds of walls: brick wall, stone wall, and fence, and finally Su Yan chose to use a net woven with hemp rope to surround the residence as a wall.

The brick wall is the best, but the dragon tribe does not have so long to build a wall in the new home, and this new home is only temporary, in the future, the dragon tribe will use fired adobe bricks to build another new home after clearing the wasteland not far away, and now this new home may be abandoned in two or three years, it is not suitable to spend a lot of manpower and time to build a brick wall and stone wall for the new home, the fence construction time is relatively short, but it is too simple, and it can't play much of a barrier to the beast and the enemy.

It's different if it's replaced with a net, a big net woven with No. 3 hemp rope, the mesh can be larger, but you can't allow beasts and people to drill through the mesh, such a big net is also fast, although the net is not hard, but it is enough to block beasts and enemies, maybe the net will become tattered in a few years, but by that time the dragon tribe has moved into a new home built of adobe bricks.

Some of the pregnant women in the tribe and some people who are close to adulthood are unable to go out to work, and they also do some things such as weaving fishing nets, straw sandals, rattan baskets, and hemp rope in the tribe.

Thanks to last year's bumper harvest of hemp, the dragon tribe has enough hemp rope reserves, and minus the hemp rope used to weave fishing nets, the remaining hemp rope can almost weave a net to enclose the dwelling.

After thinking about the whole thing, Su Yan asked a few clansmen to go down and inform, and summoned most of the pregnant women in the tribe and those who were close to adulthood.

In less than ten minutes, more than 100 people gathered in the open space in the middle of the residence, and Su Yan walked over with two wooden sticks, one long and one short.

"There is one thing that everyone needs to do, I need everyone to weave a net with No. 3 hemp rope, the length of the net is not limited, the width is according to this long stick, and the length of the grid is according to this short stick." Su Yan took the wooden stick and said to the clansmen in front of him, the long wooden stick is about two meters long, and the short wooden stick is about ten centimeters long.

"King, we know." Hearing the task issued by Su Yan, the clansmen replied one after another, the task issued by Su Yan was not difficult, and compared with the fishing nets with finer grids, this kind of nets are easier to weave.

"Okay, you guys go ahead and do it." Su Yan waved his hand, and the clansmen wrote down the length of the two wooden sticks and walked towards the house where the hemp rope was placed, preparing to take the hemp rope to weave a large net.

It is expected that the final large net will be more than 300 meters long, and it will be carried out by more than 100 clansmen, and it will be completed by the day after tomorrow at the latest.

Looking at the clansmen who were scattered and leaving, and then at the wisdom of leading the clansmen to renovate the houses not far away, Su Yan sighed unconsciously.

Zhi is also a relatively intelligent person among the adult male clansmen, but Zhi also didn't think of the lack of walls in the new home, if Su Yan hadn't discovered this matter himself, I'm afraid that the Dragon Tribe would have to suffer a little loss this winter before he thought of building a wall.

Su Yan himself thought of this matter is normal, as the king of the Dragon Tribe, Su Yan is the busiest person in the Dragon Tribe, other people's busyness is manual labor, and Su Yan's busyness is mental work, every important thing in the Dragon Tribe is sketched out in Su Yan's mind, and then Su Yan took it out and handed it over to other clansmen for implementation.

Thinking too much, Su Yan will leave something behind unconsciously.

The dragon tribe is still a lot worse, the big and small things of the dragon tribe need Su Yan to worry about, other clansmen can not give Su Yan much help, it is very difficult to make primitive people take the initiative to think about something, most primitive people are used to obeying orders.

The wiser people in the dragon tribe are none other than the witches and witch disciples of the various clans, they are originally the wisest people in the tribes, but they can't escape the vicious circle of primitive people, and they rarely take the initiative to think about something, and it is more difficult to create.

As a result, the only tasks left of witches were sacrifices, recording knowledge, and curing diseases and saving people.

Also, it is a very difficult thing for primitive people to think and create, human beings do not know how long it took from the Stone Age to the Bronze Age, and when people learn to think and create more and more shorter, the progress of human beings will be faster and faster, the Iron Age, the Steam Age, the Electric Age, the Information Age, the interval between each era is getting shorter and shorter.

It's useless to think so much, for the time being, I can only rely on Su Yan's own efforts.

"Alas!"
