Reborn stone tools to farm

Salt is essential to living things. The chemical name of salt is sodium chloride. Sodium plays a very important role in the human body, maintaining acid-base balance, forming extracellular fluid, maintaining effective blood circulation, participating in the composition of gastric acid, etc., nerves The system, muscle contraction, and heart beating are all related to sodium ions, and its importance can be imagined.

When the human body lacks salt intake, it will start to feel tired, dizzy, nausea, rapid heartbeat, muscle cramps, and even shock.

Animals also need salt, but their intake is different from humans. Some animals can find salt-rich gravel or water sources to lick, and some replenish themselves from the salt in the blood of other animals, so drinking blood is not a problem. Scary or strange thing, men would also drink blood when they hunted muntjacs before, because they exercise a lot, the replenishment once every half a month is definitely not enough.

After everyone who was supposed to go out had gone out, Tang Zheng ran to the old grandmother and watched her carefully put away the salt: "Old grandmother, how did this come about?"

The old grandmother looked up at Tang Zheng, and said with a smile: "It was exchanged from the He tribe far away. It is a tribe that is much larger than the Stone tribe."

"How long will it take to get there?"

"Hmm... let's make a sunrise with three palms."

Three palms is fifteen, and a month's journey back and forth is really far enough.

"How much does it cost to change a piece of salt?"

"Three skins, there were so many before, and they are always changing."

"Can you wear it?"

"No, just take it off."

Tang Zheng couldn't imagine that a fist-sized piece of poor-quality coarse salt was worth the price of one and a half pieces of "clothes".

"Do you want salt?" the old grandmother asked with a smile when she saw her lost in thought.

"I want it, but it's far away." There will always be animal skins and the like. Tang Zheng is not worried about this at all, but the one-month journey of the moving axis is really daunting in this era without any means of transportation. , not to mention how many accidents there have been on the road, for this small tribe of more than 20 people, the people left behind are also under tremendous pressure. Maybe it is not impossible to find that your old nest has been taken away when you come back after all the hard work .

"Is your memory bad after you hurt your head?" The old grandmother lightly tapped the wound on Tang Zheng's forehead with her finger and said, "Usually I go to the Stone Tribe to change it. For an extra piece of leather, I only need to walk three times." Point to a sunrise."

Tang Zheng was stunned for a moment, then said with a sneer, "I can't remember some things."

Received the slightly distressed look from the old grandmother, Tang Zheng was relieved from the bottom of his heart, and thought to himself that he should be more careful when speaking in the future.

The Stone Tribe and the River Tribe are not in the same direction. According to Tang Zheng's judgment, one is in the south and the other is in the southeast, but the Stone Tribe is nearly half the distance away.

Afterwards, Tang Zheng asked the old grandmother a lot of questions. The Stone Tribe was probably a middleman. Apart from their own skills in tanning animal skins, they also relied on the private salt and pottery from the River Tribe trade to provide them with Such small tribes are reselling at high prices.

Animal skins are hard currency, and food is not easy to store and transport, so light and heat-resistant leather is the most suitable for trading.

The old grandmother said that the population of the Stone Tribe is more than a dozen, that is, more than 100 people, and they are fully capable of supporting continuous trading capabilities. The manpower on the road is not counted at all. I have repeatedly resold my own tanning skills, tsk, it is really profitable, really not!A little bit!envious!

If you have a chance, you must go and see it.

Tang Zheng was in a daze habitually, so the grandmother cleaned up and went to dry the mushrooms, leaving her alone when she recovered.

Standing up, my legs are a little numb after squatting for a long time. The rain yesterday made the soil a little wet, probably because it has been trampled. Walking barefoot on it leaves only shallow footprints, but the soil touches the soles of the feet. Tang Zheng is not used to the slippery feeling when it is separated, and the sticky feeling when it is separated.

Not two steps away, there were a few "cuckoo" sounds from behind, and Tang Zheng remembered that her chicken was drenched in the rain all night!

He hurriedly ran to the fence, two hens nestled listlessly in their grass nest, and two roosters squatted lifelessly, their feathers were still wet, they really were a group of drowned chickens.

Asking the old grandmother for a fruit, Tang Zheng took off two sticks from the ground and went in to see the condition of the two hens. It was raining and he didn't know if the five eggs would survive or not. The hens must be fine.

He used his fingernails to pick a few pieces of pear flesh and put them on the ground. Although the two chickens were not in good spirits and forgot to feed them yesterday, they still started eating after a while. Tang Zheng was relieved to see them.

Compared with the previous two days, these chickens are not so afraid of life. They are very easy to domesticate. After a while, they can be released. Tang Zheng really doesn't know what it is like to be a pure pheasant. Looking at the two chickens next to him The eyes of the rooster shone slightly.

After feeding the fruit, Tang Zheng began to think about building a new nest for them. Not only was it raining, but if the snow season came, he had to think about keeping warm.

There were still six or seven grass bunks that were used to build the shed yesterday, and there were still several wooden poles. Thinking about it, Tang Zheng pulled it up the mountain and continued to build the shed.

This time, the shed to be built was single-sided, only half of it. Tang Zheng put the half of the cave where Tang Zheng slept into the mask. She started thinking about getting a roof when she was half asleep yesterday when water seeped in and had to move the shed.

The work of the two of them must not be as fast as yesterday. Although the materials were all ready-made, and Midway Branch also came to help, they still didn't finish until noon.

The shed is twice as wide as the side of the kiln in the horizontal direction, but only a quarter of the length in the vertical direction. It is only required to block the rainwater within two meters.

I found two bamboo poles and split them into two centimeters wide bamboo strips as usual. Tang Zheng wanted to build a nest for these chickens.

However, when the bamboo strips were split and cut to the required length, I suddenly found that the thin rattan was thin, but it was still thick when used on it. The gap of half a centimeter was very leaky, so it didn't keep warm at all.

There were just a few wooden poles left, and an ax was used to cut a hole from top to bottom. Because they were still fresh, a complete layer of bark could be peeled off.

The inner fibrous tissue of the bark is soft and is used for binding or making ropes. Although it will lignify after a period of time, it is most suitable for this situation.

The bark is moist but not sticky. After tearing into long and thin strips, rub them with your hands briefly for later use, and then ask Laishan and Zhi to rub the rope together with her.

Take three strands and pinch the top with your left hand, drive the two strands on the right and rotate counterclockwise, and then rotate the three strands counterclockwise once at the same time. Repeat this action continuously, and you will soon be able to weave a rope.

When the rope in his hand was longer than two feet, Tang Zheng straightened up and kept bending his waist to see the situation of the other two people. At this moment, he could see his talent.

Zhi's hands are more dexterous, and the first section is still thick and thin, and then it gets better and better.And Shan's weaving was really a mess from beginning to end, even he himself scratched his head and scratched the back of his head embarrassingly when he noticed Tang Zheng's gaze.

"Okay, go and get the stone slabs and mud."

"Hey!" Tang Zheng yelled, and Shan himself was relieved, and got up cheerfully to move things.

"Remember to take two earthenware bowls to catch some water."

"Oh!"

When the mountain moved things, Tang Zheng demonstrated to him as usual, paved the ground with grass and wood ash to prevent sticking, took a piece of soil and flattened it into a circle the size of the palm of the hand, and pushed it out from the middle, making it like a shallow plate with a relatively small wall. Thick and curved, about a finger in length.

Tang Zheng's movements were always faster than that of a novice like Shan. After finishing his own work, he began to guide him seriously. Fortunately, Shan's hands were faster at kneading the mud than rubbing the rope.

After that, I dipped my hands in water and rubbed the mud strips, and stacked them up and down, and then smoothed them out with my hands. I wiped the surface of the pottery with water and smoothed it a little bit.

There are two earliest methods of pottery casting, namely the clay sheet stacking method and the clay strip coil construction method. Tang Zheng obviously used the latter method.

It is very simple to build the mud strips, but it is not easy to trim the shape of the trimmer. It takes time and great patience to rub the uneven mud strips into a smooth plane by repeatedly dipping the palm of your hand in water.

Modern porcelain technology relies on the electric turntable, which can provide a long-lasting and stable speed for the master to quickly pull out the shape he wants. In ancient times, there was no such thing or even a ball. The turntable is similar to a flat wheel. The thing is very heavy, and it depends entirely on the puller to stir up the turntable with a wooden stick, and pull the blank at a fleeting speed. The forming of a blank is an extreme test of personal skills.

Let’s not talk about whether Tang Zheng will make this turntable, and whether she can turn it, at least she will definitely not be able to pull the billet by hand. It is estimated that it will be difficult to turn the mud, 360 lines, and it is not easy to get started in any line. A small turntable can be considered for use when the mountain is trimming the surface.

When Tang Zheng finished repairing the pottery bowl in his hand, the ropes on the sticks were almost three meters long. The bowl was probably about the size of the soup basin, and the mouth of the bowl was about as big as his face.

A few people looked at the pottery bowl in front of Tang Zheng and could see the look of love in their eyes. If the things made by obsessive-compulsive disorder are successful, they will always be round and beautiful. Graphics always have an intuitive preference, after all, the moon is still round and beautiful.

Shan took a few glances and then buried himself in finishing his work. Tang Zheng went to the stream to wash his hands and came back to weave rope with Zhi. The old grandmother continued to sort her own fruits and mushrooms. Each of them had their own things to do to enrich life unexpectedly. Although I didn't have any entertainment facilities when I woke up, I didn't feel any discomfort when I went to bed early when I was tired these few nights. Of course, it would be a lie to say that I don't want modern life.

For his first work, Shan was extremely serious, and he didn't stop until the rope in Tang Zheng's hand was woven three meters. Although it was still a bit crooked and not as good-looking as Tang Zheng's, it was still very good.

"Great." Tang Zheng affirmed without hesitation.

"Master is great." Shan blushed after receiving the compliment, and was a little shy when speaking.
