All the savage is jealous, I will farm

He has never figured out why the boiled brine should be poured into the soil in the book, until now he suddenly realized that the high concentration of salt would form salt lumps after precipitation.

Then why not use these salt blocks to make a brine bed for drying brine?

"Let's go, let's go back quickly." Su Yao dragged Zhong Li and ran back at a fast speed. Zhong Li didn't know what Su Yao was going to do, so he quickly jumped across the mountains with his spiritual energy.

The two returned to the place where the salt was smelted, sorted out several flat fields in the middle of the valley where the sun shines the most, and then added a lot of firewood to the stove to speed up the evaporation of the brine.

A thick layer of saline soil with extremely high salt content was poured on the flattened brine bed. After the brine in the pot was boiled until a large amount of salt was analyzed, Su Yao and Zhongli carried the brine in the pot with their own hands and poured it into the pot while it was hot. on a brine bed.

Then take the wooden stick prepared in advance to stir and hammer the upper layer of salt soil and hot brine. As the temperature gradually drops, the salt fused by the hot brine precipitates and crystallizes, and more of them become compact salt blocks.

The salt solidifies to form a leak-proof layer so that moisture cannot seep through.

With the initial construction of the first brine bed, Su Yao asked people to bring the saline soil with extremely high salt content again and pour it on the newly built brine bed. Beds are thicker.

Until the moisture in the brine bed is dried, use a wooden rake to loosen the sand on the top, and then pour new brine into it. The brine stays firmly in the brine bed without any trace of infiltration.

"It's done." Su Yao patted the soil in his hand, smiled and said to Chu Shan and others who were watching: "I saw that you didn't follow this order, go down and make a brine bed for me."

Chu Shan and others cheered for a while, and then a group of people rushed out excitedly. The sun at noon was already hot, and the saline-alkali land was even hotter due to the special geographical structure, so the water in the brine bed was evaporated quickly. Salt molecules were faintly precipitated at the bottom of the bed.

The people were lying on the side of the brine bed under the sun to observe the precipitation of salt and whether there was any water seepage in the brine bed. After a while, they were so dizzy from the smoke that they had to hide on the side.

After making [-] small brine beds in a row, a whole day passed.

This is Su Yao's first time looking for salt, and he is not mature enough in all aspects, so he can only make do with it for the time being, and when the urgent needs of the tribe are resolved, he will find a way to completely incorporate this treasure land into the territory of the Huangping tribe.

At that time, a refined salt refining field will be built here, and high-quality table salt will be produced by adopting the most reasonable salt refining process. The Huangping tribe will no longer be constrained by others, which in turn will attract other tribes to join.

The brine bed and more than a dozen large pots are used to extract salt, and the salt in the pot can be poured out after the water has evaporated and stored dry in animal skin bags.

After half of the water in the pool is evaporated, new brine is added to it, and the salt content of the brine in the pool will become higher and higher after repeating this several times.

Su Yao took a savage bird's egg and gently placed it in the pool. There was only a shallow layer of brine in the pool, but the egg was floating on the water. It can be seen that the salt content in the water is already extremely high and can be drawn out. up.

Dig a big hole next to the brine pool and put it into a wooden barrel, and then pass the bamboo tube through the pool to guide the brine inside into the wooden barrel, and then get brine with a very high salt concentration.

After the brine is drawn, you only need to plug the bamboo tube with cotton cloth, and the brine in the center can be sun-dried in the pool, which can save a lot of energy and firewood.

When the high-concentration brine is fired in the pot, the salt precipitation speed is faster, and the precipitated salt crystals are also whiter, but the salt extracted in this way is only the most preliminary coarse salt and needs further processing.

Now that time is running out, they can only refine a large amount of coarse salt and store it in animal skin bags. The work of processing fine salt can only be completely completed when they return to the tribe.

A brine bed can precipitate three barrels of high-concentration brine in one day and one night, which is exactly the amount of a large pot.And a pot of brine can produce more than 20 catties of coarse salt, so they can get nearly [-] catties of coarse salt in one day and one night.

This kind of efficiency cannot be considered low, but it is not as high as Su Yao expected. After more than ten days in a row, the refined coarse salt has reached more than 600 catties, and they have picked up all the dry firewood on the surrounding mountains. When I go back.

At this time, it has been 20 days since they came out. If they don't go back quickly, their relatives and friends in the tribe will definitely be worried, and the soldiers also showed a slightly anxious look.

"After this round of burning is over, let's go back first." Su Yao made a decision. He estimated that this batch of salt would be enough for the tribe for a while.

"Okay, I'll inform them." Zhong Li turned around and walked out of the temporary tent.

After receiving the notice, everyone packed their backpacks. It was different from when they came. When they went back, they had to carry more than 100 kilograms of coarse salt and bags weighing dozens of kilograms. self defense.

The salt basket is specially made, and there is a piece near the neck to prevent the salt bag from touching the skin. The straps on the basket are also specially sewn with cowhide, with a width of two inches. Easy to pinch your shoulders.

The sky was gray, and the salt in the pot was also filled. Xiaoman ate enough young grass and drank enough water, and started climbing the mountain with more than 500 catties of salt on his back.

Su Yao led the bulls to walk ahead, and Zhong Li led the soldiers behind him. Just as he climbed up the hill, Su Yao had no intention of looking at the back of the hill, but saw a flash of fire in the valley two hills away.

Su Yao narrowed his eyes slightly, and used his spiritual power to look again, and found that he didn't have a blind eye. The light in the mountain depression was the light of the torch, and it was still moving slowly.

Su Yao's heart tightened. Since there is a torch, it means that there must be tribes around here. In other words, it may not be so easy for him to include this place into the territory of the Huangping tribe.

Zhong Li also noticed the fire in the opposite mountain depression. The other people's eyesight was not as good as the two of them, and there were two big hills separated them, so they couldn't see very clearly.

"You go first." Zhong Li said coldly.

Fortunately, they were used to traveling at night, so they could walk in such a gray sky, so they didn't use torches, just to hide their tracks.

Chu Shan saw that Su Yao and Zhong Li looked very serious, and knew that the situation was urgent, so he led everyone down the mountain quietly, without making any sound during the whole process.

Su Yao was relieved when the soldiers disappeared into the mountain depression. He still didn't know how many people there were on the other side, so it was the best choice not to contact them head-on.

"What should I do?" Zhong Li asked Su Yao.

Su Yao shrugged: "I haven't thought about it yet, but I can't let them know about the traces of salt refining, and I must hold this place in my hand."

In the thousands of years of history in the place where he grew up, no matter how the current situation changes, the refining and marketing of salt will always be in the hands of those in power. Can prove the importance of salt to a faction.

Su Yao would never allow the source of salt he found so hard to fall into the hands of others.

"But we have to find a way to destroy the traces left." Su Yao's words fell, and the majestic spiritual power was struck out from his hands. Within a few breaths, there was a rumbling sound in the valley, and dust floating up Covered the tracks.

The light of the torches in the opposite mountain col became visibly flustered and moved far away at an extremely fast speed. Obviously, those people didn't dare to come over to find out what was going on here without knowing what the situation was.

Looking at the backs of those people who turned around and fled, Su Yao breathed a sigh of relief: "They came here to hunt, they didn't notice the smoke rising from the valley and came here specifically to find us."

Zhongli's performance was even more dull, if those people dared to come over, they would all be killed.

But he wouldn't say this in front of Su Yao: "Let's leave here first, so what if they know our whereabouts? If you want this place, just take it here."

Su Yao was amused by his domineering speech, and reached out to pat him on the shoulder: "Who's leader is so diligent when he carries such a heavy thing on his back and dares to speak wildly?"

Zhong Li stretched out his head and motioned Su Yao to touch it again.

The slightly tense atmosphere relaxed in the interaction between the two, as Zhong Li said, they were not in a hurry.

The journey back was a bit slower, but because I had already walked through it once, I didn’t need to look for directions like I did when I came here, so it didn’t take much time. After walking for three days, I reached the closest mountain to the plain.

The surrounding vegetation gradually turned green, and the mood of these people gradually relaxed. Chu Shan shouted at first: "Persist for a while, and we can use the cart to pull the salt over this mountain."

Everyone was excited for a while. They were actually very tired. Not to mention that they could not bear the weight of more than 100 kilograms on their shoulders. The coarse salt produced a very unpleasant smell under the sun. It is the most unacceptable to them.

Seeing this, Su Yao waved his hands again indiscriminately, and a gust of cool wind drifted past, making everyone squint comfortably.

After finally climbing to the top of the mountain, their knees trembled when they walked down the mountain, but no one slowed down, and they persisted with the breath in their hearts.

The hard work paid off, and finally reached the foot of the mountain. Everyone looked up at Su Yao and Zhong Li, waiting for their orders.

Su Yao lived up to everyone's expectations: "Rest on the spot for two hours, and Chu Shan will take people to find the wooden frame cart we hid."

"Received." "Okay~" The soldiers put down the panniers on their backs, and after sitting on the ground, they quickly took off their jackets and exposed them to the wind. On their shoulders, the worn out flesh left green and red marks .

The salt on Xiaoman's body was also taken off. Although Xiaoman didn't understand human language, the soldiers didn't treat him as an animal, but as their companion, eating and living together, and resting together.

Not long after he was born, he came back with three wooden carts, the largest wooden cart was pulled by Xiaoman, and the remaining two smaller ones were used as spares.

The lunch was long-lost bacon. After eating satisfactorily, everyone took a nap in place. After the hottest noon passed, the group began to load the car.

Brute bulls have great strength, but they are not good at carrying heavy loads, so they only carried more than 500 catties of salt along the way, and their structure is more suitable for pulling carts.

In the tribe, everyone has not eaten salt for two or three days, and the panic of lack of salt makes them uneasy even to work.
