In the next half month, the whole tribe entered a tense and busy life, in an orderly manner.

In the first few days, Ding Qi trained with the hunting team, standing in a military posture in the morning, and clearing the snow in the afternoon, opening up the road to the lake, the forest, the bamboo forest, and the ash kiln. After everyone is familiar with the content of military training and implements it in accordance with military regulations, Ben will take over the training of physical fitness, skills, and weapons. Sometimes there are physical confrontations and short snow pulls in order to develop in the direction of the Scout.

Of course, in order to improve their personal survivability, Ding Qi will spare an hour every two days to teach them grappling fighting techniques, only one offensive and defensive move at a time, so that everyone can learn it in two days, and then teach new content after learning. Seeing that this magical move could easily defeat the strongest person in the hunting team, everyone's enthusiasm for learning suddenly increased, and they didn't let go of the rest time to practice martial arts.

As for the group of slaves and Shiraishi led by the red deer, except for the beginning of the snow clearing and opening the road with the hunting team, the rest of the time is their own snow clearing around the snow road and collecting forage. Now the two horses have no extra food supplements, so they can only eat more forage to avoid losing fat. The forage stored before was only prepared according to those domesticated animals, and there was no plan for two horses, and now they can still have some forage to eat, but the more they go on, the less forage will become, and it will not be easy to find food under such thick snow when the time comes.

Red deer will expand the area of snow forage every day, and in the process of looking for forage, they can also find additional fresh meat, such as wild mice and hares, etc., these things will be rewarded by red deer to everyone, which is also regarded as a reward for everyone, which makes them more motivated to work, and the forage they find every day can be piled up into a hill.

They piled up the straw according to the way that Ding Qi taught, which was much more neat and orderly than the original way they had piled it haphazardly, and they became very interested in this method, and they even studied hard and then divided into teams to see which team was stacked more and more neatly.

Novelty is unstoppable to primitive people, who are like a sponge, hoping to absorb more knowledge and skills. For example, the people of the hunting team, for a small rope sleeve technology, they will study for a long time, come up with the principle of this rope sleeve, and integrate and develop a new rope sleeve method.

In the tribe, in fact, the most tired is the support group hosted by the flower, who has to prepare three meals a day, whether it is baked or cooked, from morning to night. He is also busy taking care of the animals in the yard, cleaning up the manure and sometimes delivering the animals. One more important thing is that they have to quickly make the remaining animal skins into animal skin clothing.

According to Ding Qi's current feeling, the weather temperature has reached about minus 20 degrees, but as the weather gradually gets colder, it is estimated to reach around minus 35 degrees. At such a low temperature, some people's animal skin clothes can't withstand it, and they need to add more clothes.

In addition, most of the clothes of the hunting team were made halfway back with Ding Qi, and they were not neatly done, and some places were still exposed, so that they would also feel cool, so their clothes had to be sewn and mended by the people of the support group.

The Witch Deer is also busy, and since that night, she has focused her life on teaching the newcomers to the tribe the rules. Everyone has a lot of respect for the witch, so they will strictly follow what the witch says, and there will be no big resistance, and they will even supervise what others do. The deer also took out the reward and punishment measures used by Ding Qi before, and implemented them after a slight modification, and the effect was also very good.

There was a lot of wood outside the hut where Tinch was, and the slaves had cut it back from the forest and placed it under the hut at Tinki's request. At the side of the wooden shed, Ding Qi set up three clay pots there, and two rows of wooden planks were erected on the side to block people's view.

At this time, in the three clay pots, the filtered brine was boiling, and some salt crystals had precipitated out, and the color looked white, which looked much better than the original coarse salt.

This is the work that Ding Qi put down other things and prepared to start two days later: making refined salt. The person who added firewood to the fire next to him was grass, who was specially transferred by Ding Qi from the support group to refine the coarse salt.

Coarse salt goes through four processes: dissolution, precipitation, filtration, and evaporation, and finally refined salt can be prepared

There are two large clay pots in the center, from right to left, where the brine that has been dissolved and the impurities that are being precipitated and separated are placed, and the brine that has been filtered.

The first two processes are not difficult, and the key lies in the third process. If it is filtered well, more impurities will be removed, and the final salt will be more pure, without too many impurities, and the taste will be better.

Ding Qi went to the bamboo forest and cut a bamboo about 15 centimeters thick, cut a relatively long bamboo knot, opened one end, and drilled a hole of five centimeters at the other end. Ding Qi cut off a two-centimeter circle at the bottom of his T-shirt and put it under the bamboo tube, stuffing about two-thirds of the charcoal on it, and stuffing it with a layer of vine fibers on the top, which was pressed very thickly. Such a simple transponder is done.

Ding Qi put the precipitated brine into the filter with a clay spoon, and the brine was filtered along the filter, first by the layer of fiber, then by the charcoal for the second time, and finally by the layer of fine T-shirt for the third time, and then the purified brine flowed into the clay jar for secondary precipitation. When steaming, a clay pot is scooped out and poured into a clay pot to heat, which speeds up the crystallization process of salt, and finally obtains intoxicating salt crystals, which are stored in a large clay pot.

Deer, stags, ben and red deer all came to see how the first refined salt was made, and when each of them took a little white salt and put it in their mouths, they were thrilled by the familiar taste. Especially Ben, he has experienced the process of turning the power stone into coarse salt, but the coarse salt at that time was still a little bitter, and the color was yellow, which is like the salt crystals as white as snow in front of him now? It was noticeably different from the previous coarse salt, and he didn't recognize it as coarse salt.

"Chief, what is this?"

The Bucks were the first to ask the question in their mind, and this was the question of several others. They just saw the process by which this kind of thing was obtained, but Ding Qi didn't tell them what it was.

"It's salt!"

Ding Qi didn't sell it, and directly said this name with historical significance, a name that has been inherited for tens of thousands of years.

"Salt? The leader, like coarse salt, has a salt character, is it made of coarse salt? ”

Ben knew about coarse salt, but he didn't know it, but he still associated it with coarse salt when he heard the name.

"Yes, it's coarse salt."

Tinch gave him an affirmative answer.

"Salt? I feel the taste of the powerful stone inside, but it is better than the power stone, not bitter or astringent, and the color is beautiful like snow. ”

The deer felt more keen, as a person who didn't know what salt was, after tasting it, he was able to tell the root of the salt, which made Ding Qi also impressed her, and looking at her eyes made the deer feel red again, and quickly lowered his head.

Red deer and grass didn't ask, they both knew, the leader would definitely say.

"That's right, Fawn is right. This salt is obtained from the power stone, but the power stone you know is not actually called the power stone, but the salt crystal. Before, I exchanged with the Ben Quli tribe, and all the power stones I obtained, that is, salt crystals, were made into the coarse salt you saw before. ”

Ding Qi smiled slightly and continued:

"The coarse salt is rough to make, and the process is very simple, that is, after the salt crystals are dissolved into brine, impurities are removed, and then dried in a clay pot. Coarse salt is still a little bitter to eat, and there are a lot of impurities in it. But after the coarse salt has gone through the previous steps, it becomes real salt, which is the refined salt that removes the essence and restores the essence. ”

Ding Qi frowned, thought for a while and said:

"But this kind of salt varies greatly from the salt crystals to the final refined salt, not only in taste and color, but also in weight. In the end, only one or more parts of refined salt can be obtained, and the loss can be as much as half, so it can only be said that there are too many impurities in the salt crystals. So, this salt is expensive and can be exchanged for more things. Then, such an expensive thing needs to be kept secret, and the production process cannot be casually told to people from other tribes, even if it is from our tribe, it can only be known to some people. ”

Several people present looked at each other, knowing the importance of Ding Qi's words, and told themselves in their hearts that they couldn't tell this secret.

After the others left, the boiling of refined salt continued. Ding Qi also called Hua over and asked her to learn how to make refined salt with the grass, and Ding Qi pointed out beside him. When Hua tasted the taste of salt and was told by Ding Qi that it could modulate the taste of food, he was so excited that he screamed and bluntly said that he would put more salt in the broth when cooking that night, presumably everyone would like this taste after eating the food cooked by the support team.

Hua did just that, putting a handful of salt in the broth she cooked that night, a handful of salt in each pot. The cute flower idea was good, but in the end, everyone felt salty and salty in the first bite of meat that night, and they all drank water after the meal, resulting in not enough water to drink that night, and many people drank cold water directly to quench their thirst.

This made Ding Qi cry and laugh, and afterwards instructed her how to put salt and how much salt to put it, so as to solve this problem and get a dry person out of the broth phobia. At the same time, Ding Qi also told the people in the support group to put less salt, as long as it is a little salty. In the 21st century, it is better to stay away from the primitive society, and if the people of the primitive era also have three highs, it will be Ding Qi's sin.

After Ding Qi handed over the matter of making refined salt to Cao, he focused on other things. For example, to make a blackboard, the board is easy to find, but there is no suitable material to make the board black, so the blackboard cannot be made, so Ding Qi has to make a whiteboard.

The whiteboard material is easy to find, which is hydrated lime. He coated a board sawed out with a saw, smeared it with a layer of hydrated lime, made ten in a row, and smoked it dry in his own wooden house. After finding a suitable charcoal pen, you can write on the whiteboard.

Since it is not easy to erase the words written on the whiteboard, Ding Qi is ready to make a fixed writing board, each board is written with different content, and it can be taken out and used when used, which is simple and fast.
