Jiang Xuan, red peony root, and stone loach returned to the Vine Tribe with three bags of salt ore, as well as edible tubers such as round potatoes.
When they saw the ancient vines on the stone mountain, the bamboo forest, and the totem pattern on the huge rock in front of the bamboo house again, they felt an indescribable sense of relief in their hearts.
Jiang Xuan believes that this is the feeling of going home.
"Chief, Chi Shao, Shi Loach, you are finally back!"
Uncaria and Nanxing ran over excitedly, and the tourists who were clearing the wasteland also breathed a sigh of relief when they saw the leader coming back.
After staying here for a few days, tourists cherish the days of having a house to live in and enough food to eat.
If something happens to the leader, this good life may come to an end.
Jiang Xuan carried a bag of salt ore and said: "It took a little longer to go, which makes you worried. Let's talk about it after we enter the house."
Jiang Xuan walked into the bamboo house, put down the animal skin bag, and took out a piece of salt ore.
Uncaria and Nanxing both gathered around and looked at the stone curiously. Nanxing asked: "Chief, is this salt?"
Jiang Xuan smiled and said: "This is salt, but it is poisonous, so you can't eat it yet."
"Ah? It's poisonous?" Nan Xing originally wanted to take a piece and taste it, but immediately retracted his half-stretched hand.
Jiang Xuandao: "Don't worry, I have a way to turn it into non-toxic salt. First take the clay pot to the stream and wash it. When it's clean, put a jar of water back."
"Okay, I'll go right away."
Nanxing excitedly carried a clay pot and went to the stream to wash it and get water.
Jiang Xuanze walked out of the bamboo house and found some soft moss nearby.
The moss is very thick and grows densely. After being washed, it can be used as a filter cloth.
The experiment of purifying coarse salt was done by many people in Jiang Xuan's previous life, and the process was very simple, with only four steps:
Dissolve, filter, evaporate, crystallize.
The most important step is filtration. As long as the water-insoluble impurities in the salt ore are filtered out, and then evaporated and crystallized, the purified salt can be eaten by people.
Of course, filtering alone cannot remove all impurities in salt ore. After all, a small number of impurities are soluble in water.
If conditions permit, it is best to further purify it into refined salt.
Jiang Xuan has no conditions now, so he can only use the simplest method. With some impurities, considering the tribe's constitution, eating them will not cause much problem.
Jiang Xuan found a thick bamboo tube, then cut off the top knot of the bamboo tube, and made a hole in the bottom knot.
Then, he spread a layer of washed moss on the bottom of the bamboo tube, then went to the fire pit, grabbed several handfuls of charcoal and put it into the bamboo tube.
Charcoal has an adsorption effect, and adding charcoal for filtration can remove relatively small impurities in salt ore.
He spread another layer of moss on top of the charcoal, added a layer of pebbles, then spread a layer of moss, then spread a layer of charcoal, added pebbles to the top layer, and covered it with moss to top it off.
Finally, he poured a lot of water into the filter and simply cleaned it.
A simple primitive filter is ready!
After five layers of moss, two layers of charcoal, and two layers of stones, most of the impurities in the dissolved salt ore should be removed.
Chi Shao and others watched Jiang Xuan making this original filter intently.
Although they don’t know its specific use, they somehow feel that this thing is very powerful.
After Jiang Xuan made the original filter, Nan Xing had washed the two clay pots, and one of the pots was filled with clean water.
"Chief, what can I do?"
Undo looked at Jiang Xuan expectantly, he also wanted to participate.
Jiang Xuandao: "Put an animal skin on the ground, put a flat stone on it, and then smash the salt ore into pieces."
"Okay, I'll go right away."
Uncaria doesn't understand why this kind of stone is called salt ore, but this does not hinder his enthusiasm for work.
He found an animal skin and two stones. One was flat and placed in the middle of the animal skin, and the other was used to break the salt ore.
Then, Uncaria took out a piece of salt ore from the animal skin bag, placed it on a flat stone, and followed Jiang Xuan's instructions to smash the salt ore into pieces.
Jiang Xuan then put the smashed salt ore into an empty clay pot, filled it to about one-third of the pot's capacity, and then began to add water, stirring continuously with a bamboo stick.
As Jiang Xuan stirred, the salt crystals in the salt ore gradually melted, the water became very turbid, and there was a large amount of water-insoluble sediment at the bottom.
Jiang Xuan let the pot stand for a while, waiting for the suspended particles in the water to fall before starting to filter.
He poured out the water in the other clay pot, put it somewhere, and handed the original filter to Chi Shao.
"Sister, help me hold this bamboo tube steady."
"Okay."
Chi Shao holds the original filter in both hands and places it on top of the empty clay pot.
Jiang Xuan picked up the clay pot filled with salt water and gently poured water into the bamboo tube.
"The patter..."
With the injection of salt water, layers of moss, stones, and charcoal filtered out most of the impurities. The water that finally flowed into the clay pot has become clearer, but the color is still a little reddish.<
/p>
After Jiang Xuan poured the salt water, he went to the stream and washed away the large amount of sediment at the bottom of the clay pot. He returned to the bamboo house and filtered the salt water again.
After he filtered it three times, the brine he got was so clear that there was almost no color visible.
Jiang Xuan put the thrice-filtered salt water into the fire pond and placed it on the rocks to cook.
This is a relatively long process and requires enough patience.
After the salt water was boiled, Jiang Xuan stirred it from time to time and smashed the remaining salt ore with others.
After they smashed a whole bag of salt ore, the water in the pot had obviously evaporated, and there was a small amount of white crystals on the inner wall of the pot.
Jiang Xuan found a piece of bamboo shoot shell and carefully scraped off the crystals.
He pinched a little salt crystal with his fingers and put it on the tip of his tongue.
A relatively pure salty taste stimulated the taste buds on his tongue.
This salty taste is very close to real table salt, with almost no bitterness and astringency of impurity salt.
Chi Shao and the three teenagers looked at Jiang Xuan eagerly, hoping to see something from his face.
“Very salty!”
This is the first sentence Jiang Xuan said.
"This is real salt, salt we can all eat!"
This is the second sentence Jiang Xuan said.
"Great!"
Nanxing was the first to cheer. He was proud that he had personally participated in the salt manufacturing process. His excitement was beyond words.
"Come and try them all."
There wasn't much crystallized salt, so Jiang Xuan gave each of them a little.
Chi Shao carefully placed the salt on the tip of her tongue, then closed her mouth and tasted the salt carefully.
After a while, her eyes became slightly moist.
"It's really salt..."
In the past, the deer tribe also had salt, which was usually obtained from larger tribes in exchange for animal skins, bones and other items.
Not only is it expensive, but it is not pure at all and has a strong bitter and astringent taste.
I originally thought that with just a few of them, we might not have the chance to eat salt again in the future. Unexpectedly, Jiang Xuan made better salt.
The three teenagers felt the same way, and they even licked their fingers clean.
Salt, something that every household in Jiang Xuan's previous life could afford, is extremely precious in this wild world.
Being able to eat salt is a blessing.
It is a very happy thing to be able to eat relatively pure salt.
