The Caveman Made Me Awesome

　　 Making leather boots is not easy.

The first is to tanning raw animal hides into leather.

Obtaining animal skins is the easiest step. There are many types of animal skins in primitive society. Ye Xi gave up conventional shoe leather materials such as cowhide and sheepskin, instead choosing a kind of anteater tapir skin.

The skin of this animal is more wear-resistant and more resilient.

Soak the peeled skin in a bucket for about four days, take out the softened raw skin, and use a stone knife to clean up the fat and meat foam on the skin. The skin of ant-eaters and tapirs does not grow hair, so this step of hair removal can be omitted.

Then you need to use a chemical solution-Glauber's salt solution.

Glauber's salt is a kind of sulfate mineral, which is generally formed naturally in places such as salt lakes. Later, Tu Shan asked Huang Feng’s slaves about the secret of salt production, and knew that their tribe had discovered a salt spring.

It took Ye Xi a day to get some natural Glauber's salt from this salt spring and make a solution of Glauber's salt.

The next step is to nitrate animal skins.

In the grassy valley, Ye Xi cleared a piece of land and asked everyone to help build a stove.

Setting up a stove is a simple task. Originally, Ye Xi asked ordinary men in the tribe to help, but when they knew about it, the soldiers like Cangpan actively took the stone to build the stove.

"Come and come, let's do these, you go and do other things!" Cangpan smiled and squatted on the ground against the stone stove.

Qi Ze half-kneeled on the ground to grind the stones to make the stones fit more closely. Without raising his head, he said to the men, "Yes, go and do other things!"

Zhuo, Mink and Tudou also squeezed in with rocks, pushing these ordinary men aside.

These guys are not reconciled and unwilling to leave.

They finally had the opportunity to help Ye Xi with things, and they heard that they wanted to make a pair of "leather boots" that would make the feet painless and comfortable. How could they be willing to go? The experience of Cangpan and their personal participation in the production of salt at the beginning, I don't know how many times they have shown off consciously or unconsciously.

But Cangpan and the others were all warriors of the tribe, and they didn't dare to defy them, so they could only look at Ye Xi with pleading eyes.

Ye Xiqing coughed: "I need your help later, so please wait first."

They were relieved.

A simple-looking man said to Ye Xi: "If you have anything to do, please tell us, we can do everything!"

"Okay." Ye Xi nodded with a smile.

With so many people doing it together, the stove was quickly set up, and the fire started quickly.

Ye Xi said to the honest-looking man: "I need a stone bucket now. Please help me get a stone bucket from the cave."

"Good!" The man's eyes lit up and he was about to go.

But at this moment, a group of soldiers rushed to the cave like an arrow from the string, and disappeared in a while.

The guys can only watch their vigorous backs in the mess in the wind.

Ye Xi shook his head, a little speechless.

Isn't it just making a pair of boots? Their posture seems to be building a rocket.

The stone bucket was quickly taken, Ye Xi put it on the fire, and then poured the Glauber's salt solution in. After the fire is heated to a temperature slightly higher than body temperature, wring out the animal skin and put it in the pot.

A group of people around were watching from a distance, all looking serious.

Watching this scene, the cone covered his mouth with his hand, and quietly said to the mink beside him with his voice: "Will it not boil the animal skins if you cook it like this?"

Diao squinted, and his voice was inaudible: "When did you think Ye Xi made a mistake?"

Cone couldn't bear the look of Mink, and responded with a soft snort.

Ye Xi found out that the water was a little too hot, and said to the guys who were waiting eagerly: "Please help me control the fire and make it smaller."

As soon as the words fell, the men rushed to the stove as if they were hungry tigers, making a fire.

Cangpan, a step late, waited for the soldiers to stop chatteringly.

"Look at them, Ye Xi said to let them do it, and we won't grab it." Hu Lu muttered, while quietly retracting the sticking left foot.

Ye Xi touched the solution with his hand, feeling its temperature, and constantly asked the men to adjust the heat, while rubbing the skin with their hands, so that the solution could penetrate better.

After a while, Ye Xi felt that it was almost done, so he took out the animal skin, spread it out on a slate, and dried it under the sun.

It takes a while to dry. During this time, Ye Xi went to the farm to see the crops.

In the process of drying, a group of people gathered around the animal skins and curiously discussed: "This animal skin seems to be different after being soaked."

"That's for sure, otherwise it's white bubble?" Someone sneered.

Cone stretched out an index finger: "I want to poke and see if the skin becomes soft or hard."

Cangpan immediately slapped his hand down, and scolded: "You will be responsible if it breaks?"

Cone pursed his lips unhappily, but after all he did not dare to poke.

Ye Xi went to the farmland and returned, it was already half an hour later.

And a group of children still whispered around the animal skins.

Ye Xi squeezed away from the crowd and saw that the skins were almost dry, and declared, "Okay, let's continue."

When the stove was turned on again, Ye Xi soaked the dried animal skins in the Glauber's salt solution and kneaded them repeatedly. When the kneading was almost done, they were dried, and then the animal skins were soaked and kneaded. repeatedly.

This step is called "eating nitrate~www.readwn.com~ After the nitrate is eaten thoroughly, remove the floating nitrate on the animal skins, even if it is finished.

Next comes the extravagant behavior.

Ye Xi put a stone basin on the stove, filled the stone basin with oil, heated it to keep the oil temperature slightly higher than body temperature, then put the animal skin into the oil, and kept pushing the animal skin with his hands so that the oil could be Evenly penetrate into the leather board.

Ye Xi took the animal skin out of the oil basin, walked into the cave, and aired the animal skin on the wooden pole that was set up in advance, and let it dry naturally.

Even if the hide is finished tanning.

Zhuo looked at the completely different animal skin curiously, and asked Ye Xi: "Can it be made into boots after it dries?"

Ye Xi shook his head: "There is still one thing missing for shoe soles."

The sole cannot be made of animal skins. It must be thick, wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, and elastic. In the previous life, most shoe soles were made of synthetic rubber, synthetic plastic, or recycled leather, or even elastic cardboard.

Here, Ye Xi can luxuriantly use natural rubber as soles-the benefits of natural rubber soles are almost endless.

He remembered seeing a rubber tree in the Houlin of the Ye tribe last time, so he planned to go to the Ye tribe and pay some price. Ask the Ye tribe to sell the rubber tree to Tushan, or if it doesn’t work, just cut it. Some rubber.

Believe that this requires Ye Tribe will still sell his face. 8)
