Survival of the Orcs

Lin Mu spent the whole night drawing up a preliminary proposal, mainly about the structure and material selection of the house.His encyclopedia was really powerful at this time. In the book, there are several chapters just on the introduction of civil and architectural structures, covering the development history of architecture at various levels in ancient and modern China and abroad.

Among the nearly [-] words, some did not say a lot, and the content was so detailed that it would make people dizzy.

Suppressing their drowsiness, the two of them summed up a set of feasible plans from the densely packed text.The house is built with bricks and wood tiles as the main raw materials, and the overall frame adopts the mortise and tenon structure of ancient buildings.The structure of the house built in this way seems to be partially loose, but in fact the internal system is stable as a whole. In addition, the blue brick wall is used as the main load-bearing carrier. As long as there is no serious earthquake disaster, it is generally not a problem to live for more than a hundred years.

Early the next morning, Lin Mu called the whole clan to an open space for a meeting to discuss the assignment of tasks.

He doesn’t need to worry about how the house should be built. Everyone present has more or less experience in construction. Basically, they have to build a house once a year, so it’s not difficult for them to build it. The most important thing is to find the required materials in a short time.They have never heard of the bricks, concrete and tiles that Lin Mu mentioned, and they don't know where to look for them.

"Don't worry, everyone. The bricks I'm talking about are the final products, made of clay." Lin Mu explained to everyone in detail. "The purpose of asking everyone to come today is to ask if anyone has seen or knows the source of these soils." He took out a piece of paper from his pocket, and the paper listed the soil properties required for various types of bricks and tiles. "We Look for a slightly sticky soil with sand in it and a darker color. Another gray lumpy stone. Has any of you seen anything like it?"

"There's sticky soil and sand in it..." Heitan frowned, repeating these words over and over again.He seemed to have seen it somewhere, thought hard for a while, and said excitedly, "I know where this kind of soil is."

"Where did you see that?" Everyone asked eagerly.

Heidan tried his best to think back, and said, "Just at the confluence of the upper reaches of this river, there is a river beach where the mud is sticky. There is also at the foot of the mountain, but the mud there is white, there is no sand, and it is sticky. Much stronger."

"Really? Are you sure?" Lin Mu grabbed his shoulder and asked.If you guessed right, the white clay he mentioned later is clay for firing ceramics.That would be great if true!

"Sure!" Of course, he was sure. When he was extremely hungry, he thought about using white clay as food.

"Great!" Lin Mu was so excited that his hands trembled.The surprise came so suddenly that it made him a little hazy. "Heidan, give me a chance to be the team leader and lead people to dig the mud back!"

"Obey! I will live up to the high expectations of the patriarch!" Heidan felt very honored to be sent to the mission, and he was able to contribute to the tribe.Thinking of this, the waist can't help but straighten up quite a bit.

The ensuing discussions yielded nothing, and everyone said they had seen or heard of those materials.I had no choice but to send someone to find it.Lin Mu asked them to dig up all the black, white, and gray ones in the mountains and outside the mountains, and then verify whether they can be used one by one.Although it is time-consuming and labor-intensive to do so, the chances of finding treasure will be much higher.The mountain is so big, who knows whether the piece you dug is a rock or an ore. If they get lucky and accidentally dig iron ore, you can wake up laughing from a dream.

Lin Mu gave the sketch of the brick kiln to the two uncle craftsmen, and asked them to make final revisions and build it.He, Fles and Phil Renjie went to find the limestone.Limestone is an important building material and can be processed into cement and paint.It is written in the book that limestone is mainly formed in a shallow sea environment, and the main component of limestone is calcium carbonate.

It happened that the place where they lived was close to the coast, and they walked eastward for half an hour around the mountain.

The four searched carefully in the caves around the coast, and soon found their target.The material has been found, but how to dig it out!This is a problem. Without tools, it is an impossible task to mine ore. Everyone looks at the uneven white rock wall and finds it difficult.

"You said it would be okay to smash it with a knife?" Phil suggested.

"You are stupid! This is a rock. If the rock doesn't hit, my knife will be useless." Lin Mubai gave him a glance, what kind of stupid proposal is this.

"Then what should we do? Hitting it with a stick will definitely not work. Do you want us to move the cave back?" Phil was discouraged.It's a pity that he had all the sticks ready and couldn't use them.He looked at the protruding rock, then turned his head to stare at Renjie's hand for a while, and suddenly said happily, "Renren, why don't you become a tiger and take the stone down!"

"..." You are the iron sand palm of my hand!Still photographed.Renjie looked up to the sky without words, sometimes being overly expected by his partner may not be a good thing, "This method is good, I can try it someday when my hand is harder than a rock." A good orc cannot let his partner down , even if you know that the other party is wrong, you must point it out gently, and you must not show a trace of blame!

"We can try hitting it with a hammer." Fleiss, who had been silent for a long time, spoke out.He has been observing the surrounding terrain just now, and from the distribution of rock accumulations, it can be seen that the hardness of this stone called limestone should not be too high.If you smash it with a hammer made of black diamond, maybe you can break it open.

Lin Mu thought about it and found it feasible. "Then use a hammer to hit it, but you can't hit it directly, it's too dangerous." If you hit it with a hammer, the force will be scattered, and it will easily cause rock fragments to fly and hurt yourself. "Wait for me. Don't be in a hurry to smash it." After finishing speaking, he ran out.

Ten minutes later, he appeared in front of everyone in a hurry, with a pile of slender stones in his clothes. "Use this as a force transmission medium. It's much safer to hit it with a hammer. Also, wrap your face." As he said, he took out a towel from his backpack and helped him cover his face, leaving only two eyes exposed.

"Why is there a scent of milk?" Fles sniffed, and his nostrils were filled with a strong scent of milk, um~ it smells very good on the baby.

"Oh~ this one! It's normal for babies to wipe their drool, and it smells like milk." Lin Mu said indifferently.

Fleiss complained, "——! Why did you give me a towel for wiping drool."

"Ah! Do you mind the saliva? It doesn't matter. I also have a butt wiper and a sweat wiper here. Which one do you want?" Lin Mu raised his eyebrows and looked at him with a smirk.

"I think this one is very good, there is no need to change it!" As he spoke, he took a deep breath and exclaimed, "It smells so good, it smells like a baby!"

Lin Mu pouted.Too fake!

Fles took the stone hammer and smashed it vigorously.The rock swished down, and after a while, there was a pile of rocks on the ground.

Phil looked at the side for a while, feeling itchy hands, looked around, and found a big rock with sharp edges and corners not far away.His eyes lit up immediately, and he ran over excitedly, and brought the stone back. "Fles, get out of the way, let me do it."

Fleiss let out an oh, obediently gave up his position, and walked to them.

Phil adjusted his position, and after aiming at the target, he raised the stone and smashed it hard.

There was a loud noise, and everyone seemed to feel their feet trembling, followed by the sound of gravel falling.

"You are strong!" They didn't know what to say anymore.Only Phil could have imagined such a brutal way of throwing stones.Thanks to him, he dropped a lot of convex stones on the rock wall.

Phil picked up the stone and handed it to Renjie, "Renren, try it too, it's fun."

"Okay!" Renjie took it, warmed up for a while, and exerted strength.The stone flew out with a whoosh, and then a small piece of the cave collapsed. "It doesn't seem to be strong enough." Scratching his head, he felt a little embarrassed.

"You guys are enough. If you hit it any further, the hole will collapse." One and two are strange men, and they are not strong enough!

Phil pouted!Look at him faintly!

I can't get enough of it!

The four of them worked hard all morning and got six baskets of limestone.Everyone expressed their satisfaction and pushed the cart back.

When we returned to Taoyuan Village, it was past one o’clock in the afternoon, and the people were so hungry that their chests stuck to their backs. Lin Mu ordered a bowl of noodles for them at a very fast speed, and simply solved the problem of people’s livelihood, and started a new day. Round of high-intensity work.

Limestone needs to be fired at a high temperature to become quicklime that people are familiar with. Under high temperature conditions, the calcium carbonate in the limestone will decompose calcium oxide and carbon dioxide. The key to the success of this step lies in the temperature. The temperature must be high, otherwise the decomposition will not be complete. The resulting product will be impure.

The cave kilns that the craftsmen spent a whole morning making can just come in handy.Before firing bricks, burn lime to try the effect.

The limestone they brought back had already been crushed enough to save a lot of time.

Lin Mu directly put the rough stone into the cave.

Not long after the cave was freshly baked, the soil was not completely dry, so Lin Mu didn't dare to put too much, so he put in one-third of the cave's capacity.Then put in the firewood, wait for the temperature to rise, then pour in the charcoal and burn it together. The heat emitted by the charcoal burning is very considerable. According to data, the heat emitted by the charcoal burning is [-] times that of the firewood.The role of firewood is to control the temperature, so that the temperature of the cave kiln can be raised slowly within a certain range, so that the temperature does not rise too fast at once, and the rough stone is heated unevenly, cracked and burnt, and the decomposition and oxidation are not complete.At the same time, it also provides a good environment for the burning of charcoal, saving the time of lighting.

Lin Mu is busy processing lime here, and everyone is not idle. One group uses the stove to burn charcoal, and the other group is making bricks.In the morning, Lin Mu had already told them the steps of firing bricks. Before firing the bricks, they had to be molded into shapes, and the length, width, and thickness of each piece had to be the same, otherwise the finished product would be unusable.After the adobes are ventilated and dried in the shade, they are placed in a brick kiln, where they are fired continuously for a day and a night.

The inside of the cave was burning hot, and the hot air hit his face, making his cheeks flushed and sweating profusely.Lin Mu estimated the time, it was time to put the charcoal.

"Fles, bring the charcoal here." Lin Mu wiped off his sweat, paying close attention to the situation in the cave.

"Go to the side and rest, I'll come and see." Fleiss touched his flushed face, feeling depressed and uncomfortable.

"Okay! You just need to pay attention to the fire. When you see the charcoal is burning red, close the hole." Lin Mu told him the precautions, and quietly walked aside to breathe.Hot SI him!

Two hours later, the lime is fired, and when it cools down to about the same level, it can be taken out and smashed for secondary processing.

Lin Mu looked at the pile of quicklime with some trepidation. It was the first time he made it, and he didn't know if it would be successful.I picked a big one and tapped it with a hammer. Just a little bit, the limestone was broken into slag, and the gray powder was spread on the yellowish-brown ground.

Lin Mu twisted a small piece and put it on his fingertips to grind it. It was not as smooth and delicate as powder, but it felt a little rough in his hands. He was still not sure whether it was stone powder or lime powder.

How to prove it is quicklime!Lin Mu frowned and thought for a while.The characteristic of quicklime releasing heat when it meets water came to mind. "Whoever brought water, pour some in here." Lin Mu said, pointing to the powder on the ground.

"Oh!" (Master, I have it!) Case loudly screamed, then shyly stepped forward, lifted his legs, hush ~~ A warm current slowly sprayed out.

Lin Mu was dumbfounded, this, this, what is going on!

The powder on the ground suddenly rose into bursts of white smoke!

Probably... succeeded... right!
