"Isn't it just making clothes, what else can you do?"

Anna rubbed the dried cowhide with her small hands and said, this bison leather is thicker than ordinary domestic cowhide, rough, after drying, it feels extremely hard to the touch, and a little heavy, so it is made into clothes to wear, in fact, it is not as soft and comfortable as wild boar skin or hare skin, most of the people of the Yan tribe only use bison leather to cover tents and other aspects.

Moreover, once this kind of skin is dried, it will become brittle and hard, only suitable for fixing somewhere, and if it is made into clothes and worn, it will soon be broken, so in the end, the bison leather is used less and less, and finally has to be thrown aside, let it dry naturally, and then piled together for people to take at will.

Lin Yuan was actually also on a whim, and suddenly he had a flash of inspiration, he had been thinking about the other effects of animal skins for a long time, and just as Anna said it, he decided to try again.

Of course, this must not be known to Anna, so Lin Yuan didn't have much to do, he walked to Anna's side with a calm face, touched the cowhide that was close to drying, and then called a Yan guard nearby, who was in charge of managing these slaves.

"Lord Yanwang......"

This guard stood respectfully behind Lin Yuan, waiting for further instructions.

"You're in charge of this...... Slaughterhouse, right? Lin Yuan asked unhurriedly, and the Yan Clan guard hurriedly replied:

"Yes...... I'm the ...... of these slaves."

"Well, that's okay, let me ask you, how many of these animal skins, bison skins, do we still have?"

The guard hesitated for a moment, then spread his hands and plucked them with his fingers, as if trying to calculate something, but being constrained by his intelligence, he finally gave up the arithmetic, and then blushed, drew a great circle in the air with his hand, and then said in a rough voice:

"So...... Many, full of a tent. ”

Lin Yuan couldn't help but smile dumbly as he watched this primitive man try to draw a circle that was large enough, and then quickly regained his seriousness and let the guard leave.

Then he said mysteriously to Anna:

"This cowhide, if used properly, is not as simple as making clothes, adding tents or anything, you know? If I'm not mistaken, in the near future, we Chinese invented the world's first armor - leather armor ......."

"Leather armor?" Anna looked surprised, no wonder, she never seemed to have been exposed to this knowledge, and she still reacted to this word for a long time before she reacted.

"That's right...... It was worn on the body as a kind of armor and was useful until the Bronze Age......"

Anna pursed her lips and said:

"Cut...... Don't tell me what kind of games you've played to make leather armor merchants, can you? ”

Lin Yuan scratched his head in embarrassment and said:

"Haha, that's not true, but when I was a kid, I played a game called Worker Talk, which said that the basic process of making leather goods needs to make leather goods, let me think about it...... It seems that it is to be made into raw cowhide first...... The tanning material is then added to make the cowhide mature...... However, our needs are only strong and durable, so raw cowhide will do. ”

Anna gently patted the cowhide in front of her with her little hand and said:

"You, you...... I really think you're ...... It's like a person who knows everything, can you really learn so much by playing games? ”

Lin Yuan nodded seriously and said:

"Yes, actually, let's ...... In fact, in foreign countries, a lot of science education work is carried out through games...... Alas, forget it...... It's getting late, so let's go back early. Lin Yuan said.

Anna nodded, and left with Lin Yuan.

The next day, Anna put the matter of animal skins discussed with Lin Yuan today temporarily behind, for her, as long as Lin Yuan determined something, Lin Yuan naturally had a way to do it, so she put her mind at ease and devoted more attention to the daily management of the tribe, for Anna, she also had to complete other management work of the tribe every day, such as the Suiren clan to borrow a batch of clay pots, the Huaxu clan to use a batch of corn, the Bai Tu tribe handed over dozens of various prey, The Shennong people demanded that the Tu people return the several herbs they owed...... and other miscellaneous things, to a certain extent, Anna has become the general secretary of the Yan Tribal Alliance, and she is responsible for the daily affairs of all sizes, and she seems to enjoy it, because some work reminds her of the feeling of being a middle manager in the company.

For Anna, the Yan Alliance seems to be a group enterprise, and the six tribes are like the various branches of the group, hunters, slaves, knitted women, butchers, etc. seem to be the positions of various departments within the enterprise, she herself is the general manager and CEO of the group, and Lin Yuan is the chairman of the group.

In addition to wearing animal skins instead of white shirts, she has almost returned to her former work as an urban white-collar worker, and seems to have been completely immersed in the daily management work, and has found her own happiness from it.

But Lin Yuan did not forget the piece of cowhide, since that flash of inspiration in his mind, he would stay in that slaughtering area every day for a while, carefully observe, a few days later, he gathered a group of slaves, collected several materials from all over the tribe, namely plant ash, lumps of lard, butter, vegetable oil pressed from soybeans, and piles of wood.

Lin Yuan planned to conduct a small experiment, because he didn't know how to make animal hides into usable raw cowhides, he only remembered that he needed to use some solvents to transform certain substances in animal skins before he could convert raw animal skins into raw leather.

Whenever Lin Yuan started experimenting, there was a circle of primitive people around him, including many elite members of the Yan clan, everyone was curious to see what amazing miracles their leader was going to do, and Fu Xi took a group of young believers in red clothes to stay by Lin Yuan's side early, serving as assistants for Lin Yuan's work.

A few days ago, Lin Yuan experimented with adding water to plant ash, soaking animal skins, and then taking them out to dry, making dried animal skins with a white color, but this kind of animal skins are no different from ordinary dried animal skins except for the difference in color, the same dry and hard, and even if a little force is applied, it will break, and it is very brittle.

It is so hard that it must not be used as clothing to wear on the body, and it is also very uncomfortable, the nature of bison skin is different from that of wild boar skin and hare skin, etc., the latter also has a certain toughness after drying, and can be used as animal skin clothing.

There was no way, and then, Lin Yuan adjusted the drying time, and tried the method of drying it into a semi-dry state, and obtained a slightly softer semi-dry bison leather, which still maintained some toughness that had just been peeled off. In this way, bison leather has a relatively soft performance, can be worn on the body, and has a good degree of hardness, which seems to be used as ideal leather armor.

However, soon, Lin Yuan found that there was a fatal problem in this operation: that is, such animal skins that had not been completely dried could not be preserved for a long time, and normally, after a few days, the undried blood, minced meat and other substances in the fur began to rot, and finally became moldy and smelly, and some maggots would be born, which would soon rot and become unusable.

No, this method is not possible, it seems that this road does not work, so what else can be done to keep the hides soft and moist, but also not rotten? Lin Yuan thought about it, so he came up with the idea of grease, because a substance like lard butter that is solid at room temperature is almost difficult to rot naturally, it seems that grease itself has the effect of resisting microorganisms, and grease is a thing that can easily penetrate into the leather, Lin Yuan still remembers the soft and shiny feeling of the leather shoes worn on his feet after wiping shoe polish in the future era.

So, soon, Lin Yuan began to try to apply lard to animal skins again, but the problem still existed, because lard was a coarser solid and difficult to blend into dry leather.

So, is there any way to make lard like shoe polish, which can easily penetrate into the leather? Right! Heating! This was Lin Yuan's first thought, and at the same time, he also thought that in his time, many rural families would make bacon and bacon, and it seemed that smoking could also have an antiseptic effect? Good! Then do both! Smoke heating and grease immersion at the same time!

The basic idea is certain, the rest of the work is simple, and after several attempts, Lin Yuan finally invented a more reliable production process.

First of all, he asked the slaves to carefully clean the cut animal skin, use a bone blade to cut off the remaining flesh and hair on the fur little by little, and then put it in water and wash it repeatedly to ensure that the clean animal skin is obtained, and then hang it to dry, make the animal skin into standard wool, and store it in storage.

When you need to make leather armor, first take out the sun-dried leather from the warehouse, and then put it into water for soaking, so that the animal skin can reabsorb water and restore a certain elasticity, when it is soaked to a semi-dry state, immediately take it out, start to use lard, butter, wipe it repeatedly on both sides of the leather dozens of times, and then hang it, light a bonfire below, to ensure that the fire can not burn the leather, only use thick smoke fumigation, after a long time of fumigation, the lard originally smeared on the leather, will gradually penetrate into the leatherto make the leather shiny.

Then the smoked leather is removed, and after it has cooled, it is further applied with lard, and then it is fumigated on the shelf, and so on at least three times, when the whole leather has been completely soaked in grease and has a sparkling and smoky color, it is basically done.

Finally, the leather surface is brushed with soybean oil and allowed to dry naturally, and a complete raw cowhide is made.

Lin Yuan handed over the first piece of raw cowhide for the experiment to Anna's most trusted old woman of the Huaxu clan, that was a master of animal skin knitting, after a few days of hard work by the old woman, a simple raw cowhide armor was born, Lin Yuan took the cowhide armor to the front of the Fire Temple for the first time, and in front of many clansmen, he was ready to experiment with the effect of leather armor.

When this piece of leather armor appeared in Lin Yuan's hand, everyone in the audience rushed forward, wanting to see what was going on, and the hunters of the Yan clan had no choice but to build a human wall and stop the curious and excited people around Lin Yuan, and everyone was waiting with great anticrity for Lin Yuan to show them another miracle.

Fu Xi took out the ashes from the holy fire in the Fire Temple, sprinkled them on the leather armor, and recited a long casting word, Lin Yuan patiently waited for Fu Xi and his followers to complete a complicated blessing ceremony, then picked up the leather armor and put it on himself.

This piece of leather armor, which is made entirely of raw cowhide, is a complete chest armor, which can only be put on from the head, and then with the help of others, the arm is stretched out from the hole reserved for the armor, subject to the tools of primitive people, the outside of this cuirass is very rough, and the various positions are spliced unevenly, and there are leaking rattan strings in some places. However, this did not hinder Lin Yuan and everyone from loving this armor in the slightest, and after Lin Yuan put it on, the crowd erupted in bursts of cheers.

Lin Yuan touched the leather armor on his body, a strong smoky smell mixed with the smell of grease came to his face, the taste was really not good, the first thought that popped up in Lin Yuan's mind was to wait until the future era, he must find an alternative process with a smaller taste.

He casually picked up a sharp bone blade and stabbed it hard in the chest, and the crowd erupted in exclamation!

Lin Yuan's movements were too fast, and everyone hadn't reacted yet, including Anna, she screamed and wanted to rush over with an arrow step, but suddenly found Lin Yuan standing in place and smiling evilly at her.

Lin ...... Flame King! You are crazy! How do you experiment with yourself! ”

Lin Yuan squeezed his eyes slyly, and said, "Haha, shhh......", and then waved his hand to let Anna return to the crowd, in fact, Lin Yuan was not stupid at all, he had already tried the ability of leather armor before, of course he knew that the bone blade could not pierce the leather armor, at least, he knew that his strength was impenetrable, at most there was a small hole in the leather armor.

However, this leather armor must also undergo formal combat experiments.

"Blade! You come up! ”

Lin Yuan waved and ordered, the blade standing under the stage hurriedly ran over, Lin Yuan handed him a sharp stone spear, and said:

"Stabb me!"

"......" The blade was silent, and Lin Yuan said solemnly:

"Blade, I order you, stab me!"

“…… But, the Flame King..."

"What so much nonsense, let you stab you! It's okay! ”

After hesitating for a moment, the blade gritted his teeth and gently stabbed Lin Yuan's chest with the stone spear without the slightest reaction.

"It's too light! Didn't you eat?! Lin Yuan frowned, he grabbed the stone spear tied to his chest with both hands, and pulled it towards himself, the leather armor was slightly deformed by the stone spear, Lin Yuan seemed to be able to feel the pressure on the leather armor, but the leather armor was still not damaged.

"Oooh! Miracle of the Flame King!! Vulcan miracles! ”

Only then did the surrounding people come back to their senses from their astonishment, and one by one, under the leadership of Fu Xi, raised their arms and sang loudly.

Lin Yuan smiled, it seems that this leather armor does have some effect, but ......

He snatched the stone spear from his blade's hand and stuck it on the wooden pillar of the Fire Temple, then let out a loud shout and quickly rushed towards the stone spear.

Everyone screamed, and the blade rushed over with an arrow, trying to stop Lin Yuan, but Lin Yuan's speed was faster, only to see him snort and hit the stone spear stuck on the stake.

Anna covered her eyes.

A few seconds later, a large group of people had already rushed over and surrounded Lin Yuan.

"Flame King......! You ......," the blade shouted, and the people around him chattered in a low voice:

"The Flame King...... You okay? ”

"Nonsense! With such a great force, even the stones have to dig a hole, how can the animal skin resist it......"

“…… Whining...... Flame King, why are you doing this? Wouldn't it be nice to find a slave......"

"Save people......"

Just when everyone was talking, suddenly the blade screamed, and I saw Lin Yuan in his arms, suddenly stretched out a hand, grabbed his shoulders and stood up with difficulty.

Under the incredulous gaze of everyone, he laboriously took off his leather armor and rubbed a patch on his chest, where a small bruise had appeared, but it was not broken and did not bleed.

Lin Yuan stuck out his tongue and said with a smile:

"Oops...... It really hurts......" After speaking, he picked up the leather armor and looked carefully, only to see that there was a small hole in the leather armor, and the tip of the stone spear had entered most of it, but in the end it did not break through.

Lin Yuan happily raised his leather armor, and Fu Xi took the opportunity to shout:

"Blessing of the god of fire! Miracles reappear! The armor of the Yan clan! Never break! ”

Hearing this, everyone bent down one after another, reciting the words in a low voice, and a few elderly primitives even shed tears of excitement, and they all rushed to touch the leather armor that Lin Yuan had just worn.

"Karma! Ordered, starting tomorrow, arrange for slaves to produce leather armor in large quantities at once! It's made this way! ”

Ye hurriedly answered the order, Lin Yuan turned around and walked slowly towards Anna, the corners of his mouth slightly raised.

Anna hurriedly helped Lin Yuan rub the bruises on his chest in distress, and said resentfully:

"How do you ...... Alas...... Even if you know that the leather armor can withstand the stone spear, you can't experiment with yourself! If you're putting on a show, you can find a slave to put on and try it on, you tell me about yourself, in case there is a three-long and two-short, what should we do?? ”

Anna said anxiously, as if something was twinkling in the corner of her eye.

Lin Yuan didn't look at Anna, just gently touched Anna's head and said in a low voice:

“…… Well, actually, I didn't know if the leather armor would be able to withstand ......."
