The traverser must have a golden finger - system, but unfortunately Su Yan does not have it.

In his previous life, Su Yan could only be regarded as an ordinary person in modern society, perhaps a little better than ordinary people, after all, Su Yan was a traditional Chinese medicine practitioner and knew a little martial arts, although he could not meet the standards of elite talents, but he could be regarded as half an elite.

Compared with other ordinary people, Su Yan only has two more skills, medical skills and martial arts, but in other aspects, including common sense of life, Su Yan may not be as good as others.

Now, how to extract hemp fiber from hemp straw stumped Su Yan, Su Yan is not an all-round person, he has never learned this knowledge in his previous life, at most he understands that the stem and skin of hemp can be used to weave linen, spin thread, make ropes, weave fishing nets, make paper, etc., and then almost nothing is known.

I don't know if I don't know, it doesn't mean that Su Yan has to give up this matter, weaving linen is an important process that the Dragon Tribe must go through in the future, and when the population of the Dragon Tribe increases, everyone can't wear animal skins, clothes made of linen are a good choice, even now, in the summer, you can change the clothes made of leaves to clothes made of linen.

You must know that when the linen weaving technology is improved to a certain level, linen can even be comparable to silk.

Su Yan doesn't expect to be able to weave hemp now, but he also needs to extract hemp fibers from hemp straw, use hemp fibers to weave hemp rope, and then use hemp rope to weave fishing nets, which is more difficult to weave with hemp thread, which can be done later.

I don't know how to do it, I can only try step by step, since the stem and skin of hemp can extract hemp fiber, then peel off the hemp skin from the hemp straw first.

Bringing a hemp straw, Su Yan personally tried to peel the hemp skin, but found that it was not easy to peel off the hemp skin intact, this is a technical job, if there is a knife, it will be easier.

After wasting a lot of energy, Su Yan peeled off the hemp skin on a hemp straw.

One thing Su Yan didn't know was that the hemp skin peeled off from the hemp straw was not the same as the stem bark used to extract hemp fibers, more precisely, there was an outer epidermis outside the hemp skin, and it was the stem bark that was left by grinding off this outer epidermis.

There are a total of five large bundles of hemp straw, if Su Yan peels off the hemp skin by himself, he doesn't know how long it will take to finish, and it is better to find the clansmen to do this kind of time-wasting thing.

Su Yan gathered six pregnant clansmen to demonstrate how to peel off the hemp skin of the hemp straw, and the other six people tried to peel off the hemp skin with a hemp straw, and sharp stone chips or pottery shards were indispensable.

It took nearly two days for all the hemp straw to be stripped of the hemp skin, and Su Yan harvested a large bundle of hemp skins.

In autumn, the daytime of the clansmen is undoubtedly very precious, but Su Yan used up the two days of the six clansmen, which can be called a "waste".

However, no one will gossip, the most important of which is Su Yan's identity as the "king", and the second is that some strange labor that Su Yan asked the tribe to do may bring new things to the tribe, such as fish cages, pottery, houses, Teng Dun, peppercorns, etc., each new thing will bring big or small changes to the tribe.

In the eyes of the tribesmen, this is a testament to God's favor for the dragon tribe, and they are more than willing to participate in the king's creation.

The hemp skin has been completely peeled off, so what to do next, how to separate the hemp fibers from each other.

After thinking about it, Su Yan felt that he could try soaking it in water, soaking the hemp skin softly, and seeing if he could separate the hemp fibers in the hemp skin into threads, which was the only way Su Yan could think of.

He brought a complete large pottery, filled it with three-quarters of the water, and then Su Yan immersed some of the hemp skins in the water, and then came over every once in a while to observe the changes in the hemp skins in the water, and even picked up a hemp skin to try to tear the hemp fibers.

After soaking the hemp skin for about two days, the hemp skin has become soft, and at this point it is easy to tear a trace of hemp fiber off the hemp skin by hand.

Su Yan spent a little time tearing off all the hemp fibers on a piece of hemp skin, and finally got two things: a trace of hemp fibers and a strip of hemp with a rough outer skin.

At this time, Su Yan knew that there were no hemp fibers in the outer epidermis of hemp, and the outer epidermis was almost useless.

Having determined that the hemp fibers could be separated by water immersion, Su Yan immediately brought two large and complete pottery vessels filled with water, and then soaked all the remaining hemp skins in water.

In this process, Su Yan also found a rule, the longer the hemp skin is soaked in water, the easier it is for the hemp fibers to separate, and of course, the soaking time should not be too long.

Hemp fiber has been obtained, and then the primary product of hemp fiber - twine, this step is relatively simple, put a few thin hemp fibers together and rub them into a strand of hemp thread and dry it in the sun, the hemp can be thick or thin, depending on the specific needs.

Under the same thickness conditions, the weight that hemp rope can bear is definitely much heavier than that of straw rope, the hemp fiber is strong, not easy to rot in water, and has a waterproof effect, hemp rope is definitely more suitable for weaving fishing nets than straw rope.

At present, the dragon tribe mainly uses fish cages to fish, and fish cage fishing is indeed several times higher than the way of spearing fish with sharp sticks, but the fish cage is woven with grass rope, so that the life of the fish cage is very short, and weaving fish cages is also a more important labor of the dragon tribe every day.

If the straw rope is replaced with hemp rope, the life of the fish cage will be greatly improved, not only the fish cage, but also the hemp rope can be woven into a fishing net, fishing in the big river, fishing with a fish cage is not very applicable, and the efficiency of fishing with a fishing net is higher than that of fishing with a fish cage.

The small river in front of the dragon tribe should be a tributary of a large river, or a tributary of a tributary, and the fish in the small river are all swimming from the big river, so the fish in the small river are endless, no matter how the dragon tribe catches them every day.

But judging from the current population of the dragon tribe, it will not be long before the small river will reach the upper limit of the population that can withstand it, and then the dragon tribe will choose to move, preferably next to the big river, and still use fish as the main food, at that time fishing nets are very important to the dragon tribe.

After drying the hemp rope, Su Yan harvested a long hemp rope that was only a few millimeters thick, Su Yan was not in a hurry to use the hemp rope as a weaving fish cage or fishing net, for the time being, the dragon tribe did not have this demand, not to mention that the hemp rope was too little, I am afraid that it would not be able to weave a big net.

In order to catch more fish in a limited time, the dragon tribe's fishing team moved towards the upper and lower reaches of the river, and Zhi even led people to cut down two big trees laboriously, and set them up on the river as a small bridge, allowing the tribesmen to go to the other side of the river to fish.
