In the end, Ye Feng only promised him, there was no way, the people of the tribe needed to eat, fortunately, it was only 20 pairs of shoes, he called a few people, and it didn't take much time to make it up.

The flood came and went as fast as it could, raging in the valley for three days before slowly receding. Seeing that the flood waters had almost receded, the people of the Rock Tribe put on straw sandals and set out to find trade with other tribes.

And the Xingyue tribe had to go out to find food, and due to the raging floods, the animals here basically ran away, so they gained very little.

The men were divided into two groups, and they had to run much farther than usual to get a decent harvest, while the women, whose plants had almost collapsed due to the ravages of the floods, and who had nothing to collect, so their harvest was equally pitiful.

Ye Feng led a group, he carried a quiver made of bamboo, held a longbow, and his eyes scanned around. Suddenly, a hare came into his eyes, Ye Feng was overjoyed, raised his bow to aim, and with a bang, the hare fell to the ground.

Ye Feng stepped forward to pick up the hare, and when he looked up, he saw a shiny thing in the distance, and he looked over there, it turned out that the landslide on the mountain over there might be caused by the flood, and the rocks inside were exposed and shiny.

Normal rocks don't glow, Ye Feng's curiosity was aroused, he called everyone over, and when they saw this scene, they were also amazed.

Someone suggested going over to take a look, anyway, it was just a matter of a mountain, and everyone was also curious about it, so they nodded in agreement.

As the saying goes, Wangshan runs a dead horse, Ye Feng and they are like this, looking at it is a matter of a mountain, and they don't know how far they have walked before they get there.

Ye Feng looked at the shiny thing, it turned out that the thing was not a rock at all, but a large crystalline object, it was in the shape of a cube, with white stripes, mostly yellow, and some had translucent or transparent white.

Ye Feng picked up a piece, looked left and right and didn't know what it was, picked up a stone and knocked it, and found that this thing was quite soft, and it would break when he knocked it.

"Bah, bah, bah" A clansman next to him actually stuffed this thing into his mouth, and then immediately spit it out, with a look of eating Xiang on his face.

Seeing this, Ye Feng couldn't help but be curious, what kind of unpalatable strange taste did this thing have, driven by curiosity, he also put a small piece in his mouth.

"Well, it does have a taste, salty, it's really weird, how can a stone have a smell, wait, the stone has a salty taste, it can't be stone salt, right?"

Ye Feng hurriedly checked, judging from various characteristics, this is stone salt.

Ye Feng was so happy in his heart, haha, I found a big salt mine, I got rich, I got rich, and I don't have to drink those smelly beast blood in the future.

Ye Feng hurriedly took off his animal skin. His pants had long been worn out, and Ye Feng had to take them off and treasure them, after all, it was one of the few thoughts he had about the previous world.

Ye Feng hugged the stone salt mine on the animal skin and said to the others: "This is a good thing, you should quickly pack it up and bring it back to the tribe." ”

People were puzzled, how could a stone be said to be a good thing, but Ye Feng's performance had already convinced them deeply, and they did as he said.

Ye Feng was carrying a large bag of stone salt ore, this amount, with his current physical strength, he was a little unbearable, and finally returned to the tribe, he was embarrassed to find that how to extract the salt inside?

She worked so hard to carry it back from such a distance, but she didn't know how to extract it, and everyone was still looking at him curiously, which made her extremely embarrassed.

Soon after they returned to the tribe, the group of Doye also returned, and Heru looked at the salt ore all over the ground, and hurriedly looked up anxiously at the top of the cave.

Duoye looked at the stones all over the ground, he didn't have to think about it to know that it was Ye Feng's ghost, so he asked Ye Feng: "Ye Feng, what are you doing with so many stones?" ”

Ye Feng didn't answer directly, he picked up a piece of stone salt ore and motioned for Duoye to lick it.

Taba took the piece of ore, looked at it, stuck out his tongue, licked it a little, and then stared at it, and blurted out, "What kind of stone does this smell?" ”

Ye Feng said proudly: "That's right, this taste is called salty, and the thing on this stone is called salt, and if you eat salt, you can grow your strength, so this is a good thing." Ye Feng was afraid that they wouldn't understand, so he said concisely.

Heru, who was on the side, heard it and shouted, "It's so good, then I'll eat it too!" After saying that, he bent down and picked up a piece of ore, and sent it to his mouth.

Ye Feng felt that the roots of his teeth were sour, he saw Heru open his mouth and bite the ore, "click", Heru covered his mouth and exhaled in pain, Ye Feng dared to guarantee that if Heru used a few more strengths, he would have to lose a few teeth.

In order not to have another second goods to take a bite of the ore in the future, Ye Feng explained to everyone: "The salt I said needs to be extracted, and it is not possible to eat stones directly, and I haven't thought about the extraction method yet, so you guys will be busy with each other first, let me think about it." ”

Ye Feng frowned and thought bitterly, it would be good if there was pottery, just crush the ore, soak it in water, dissolve the salt in the water, pour it into the pottery and burn it dry to get coarse salt.

Otherwise, go find the clay and fire a pottery out, anyway, the tribe will definitely have the pottery in the future, so it's better to do it now.

Clay has the properties of fine particles, strong plasticity, good bonding, excessive thixotropy, suitable shrinkage, etc., and it is best to fire pottery with clay.

But where to find the clay, Ye Feng asked all the people in the tribe, as if they had discussed it unanimously, and they all said that they didn't know, which made Ye Feng very disappointed, it seems that the method of firing pottery will not work until the clay is found.

Ye Feng picked up the ore, looked at it carefully, and after a long time, he still didn't have a clue.

At this moment, Ye Feng saw the first clan pick up the bamboo tube and pour a mouthful of water.

That's right, you can use a bamboo tube! This discovery made his mind suddenly open up and he thought of a simple way to make salt.

Ye Feng used stones to mash the salt ore, then took a relatively large bamboo tube, put the mashed ore in it, added water, stirred it vigorously with a branch, and then waited for him to fully dissolve the salt in it, and let it stand for a day and a night.

Ye Feng found a flat and thin rigid slab, used stones to enclose a circle about ten centimeters high on the ground, put the slate on it, lit a fire in the circle, and heated the slate.

Then pour the salt water on it little by little, in fact, the salt water needs to be filtered, but Ye Feng has nothing to filter, the fabric of his pants can be considered, but he is reluctant, so he can only put the salt water and let him slowly precipitate the impurities inside.

The salt water was poured on it, making a squeaky sound, and after a while, the water vapor dispersed, and shiny particles appeared on the slate.
