"Wu, we have already piled the bottom of the kiln wall. The soil above is too soft and cannot be piled up."
As soon as Yang Cheng took the Niu Niu over, Lulu pointed to the big pit next to it and said.
In the past, Yang Cheng taught Lulu and the others how to make the walls of the earthen kiln.
Just surround the soil in circles, like a coiled spring.
One good thing about this method is that it is neatly arranged, so you don’t have to worry about making mistakes or protruding or recessing.
There is no problem with this on the lower part of the wall, but when it reaches high places, the soil will fall down due to gravity.
"Lulu, it's okay. Why don't I bring the mud cow over here? As long as it's here, there will be no problem."
Yang Cheng smiled and said something to Lulu, and then patted the Niu Niu on the head.
"Silly cow, hurry up and spit out the mud for me."
"Moo——"
Xi Ni Niu glanced at Yang Cheng resentfully.
I just knew that nothing good would come from following you here.
Niu Niu didn't want to vomit, but his mind was fettered by Yang Cheng, so he had no choice but to vomit a few mouthfuls of mud on the ground.
"You stupid cow, you are fooling me, aren't you? This little is not enough, keep vomiting on me!"
Yang Cheng looked at the mud on the ground, which was the size of a few poops, and patted the mud cow's head to make it continue spitting mud.
"Moo——"
"Pooh!"
"Pooh!"
The mud cow had no choice but to spit out several mouthfuls of mud on the ground.
"That's right."
Seeing that with the efforts of the Niu Niu, there was a lot more mud on the ground, Yang Cheng nodded with satisfaction, then patted the Niu Niu's head, took a few fruits from its back and placed them on the ground.
"Well, don't say I'm treating you badly. Just take these fruits and eat them to replenish some energy. You'll still have something to vomit later."
Xiniu Niu saw the scattered fruits that Yang Cheng put on the ground, and listened to his words. He suddenly felt that his future was hopeless, and his eyes were filled with darkness.
Yang Chengke ignored Xiniu Niu's inner thoughts and turned to Lulu and said:
"Lulu, you can use this mud to apply it on the kiln wall. You have to go faster, otherwise the mud will dry out after a while."
"Yes, Wu."
Lulu responded and hurriedly smeared the mud spitted out by the mud cow on the kiln wall. Yan Lin and other beast-eared ladies also went to help.
Yang Cheng watched them work for a while, and then looked at the large pit that was dug, three meters long, one meter deep, and three meters wide.
I feel that it is not very safe to just smear the mud on the walls of the earthen kiln.
Although the thin mud of Niu Niu almost acts like cement after solidification, it is still thin mud after all, and it will still fall off when it rains.
The best way is to build a load-bearing wall on the newly built clay kiln, which can share the pressure of the kiln wall.
Yang Cheng did whatever he thought of.
While Lulu and the others were building the walls of the earthen kiln, he found several other tribesmen and asked them to find some flat stones from the stones collected by the quarrying team.
Then put these stones in the middle of the kiln pit and arrange them well.
Stones are not bricks. Yang Chengcheng asked these tribesmen to try to keep the stone walls as straight as possible, and then use the mud spitted out by the mud cow to fill some gaps in the stone walls to make the stone walls as strong and solid as possible.
Finally, another layer of soil was placed on both sides of the stone wall and hammered down.
The overall earth and stone wall is half a meter shorter than the kiln wall.
Because Yang Cheng wants to be the final support "pillar" on it.
They are said to be supporting "pillars", but they are actually some slender small wooden sticks, placed every thirty centimeters. The two ends of the small wooden sticks are in contact with the newly built kiln wall, supporting the weight of the kiln wall.
Don't worry about these small wooden sticks being damaged by fire.
These small wooden sticks are the materials Yang Cheng brought back from the exchange ceremony this time. Although they are not invulnerable to water and fire, they are also very resistant to burning.
Moreover, Yang Cheng also painted a layer of reconciled soil on the small wooden stick, turning the small wooden stick into a "little mud stick".
After completing this step.
Yang Cheng asked Lulu to continue mixing with mud and build the kiln wall.
With the endurance of the wooden sticks and the mud vomited out by the mud cow, the kiln wall was built very quickly, and soon more than half of the kiln wall below was successfully built.
But there was a problem with the upper half of the kiln wall.
Because the overall shape of the earthen kiln is similar to a yurt, the bottom can be built vertically, but when it comes to the top, the circles need to be smaller than each other, making it a cylindrical shape with a larger bottom and a smaller top.
It is not difficult to build up the reconciled mud in circles. At most, it only takes a little extra mud to make the mud cow vomit more.
But going up circles like this, it's easy to make one side bigger and the other smaller. There are no rules and it doesn't look good at all.
Lulu realized this problem after trying it a few times.
Now she is looking at Yang Cheng with her big blinking eyes, hoping that Yang Cheng can help her solve the problem.
In Lulu's eyes, witches are the greatest and most omnipotent.
Naturally, Yang Cheng did not disappoint Lulu. Under her expectant gaze, Yang Cheng took out several long wooden sticks.
Although these long wooden sticks are collectively called long wooden sticks, their lengths are not the same.
Each of them is shorter than the other. If you are careful, you can still see that these long wooden sticks are arranged according to a certain arithmetic sequence.
The longest one is 1.5 meters, the one below is 1.3 meters, and the one below is 1.1 meters...
Lulu was considered a smarter beast-eared girl and had a natural advantage in making pottery and dealing with mud. When she saw these wooden sticks, her eyes lit up and she thought of something.
"Here, Lulu, here you go."
Seeing this, Yang Cheng didn't tell Lulu what to do, but directly handed the long wooden stick to Lulu.
Lulu took it and thought about it.
First take the 1.5-meter long wooden stick and the 1.3-meter long wooden stick in your hand, and throw the rest aside.
Then Lulu stacked the two wooden sticks together and nailed their centers with two small sticks, so that an original version of the "second hand and minute hand" appeared.
With these two things, it would be easier to handle. Every time Lulu made a small circle of mud, she would move the wooden stick to see if it was twisted.
If it's crooked, realign it and put mud on it again.
Although this speed is a bit slow, it is very accurate and the resulting kiln wall is very beautiful.
While Lulu was building the roof of the kiln, Yang Cheng released the improved flame technique to bake the bottom of the kiln.
I saw a tongue of fire spraying out from Yang Cheng's palm, like a small flamethrower, and sprayed onto the lower half of the kiln wall that had been built, and the flames were splashed away.
Wherever it went, the originally moist mud was dried out and became hard.
"Yes, Not Bad!"
Yang Cheng's favorable impression of primitive society has increased slightly.
There is witchcraft, this fire magic is the original version of "drying machine".
Yang Cheng dried all the lower parts of the kiln walls to make them strong.
Lulu is almost done with the upper part.
However, Yang Cheng did not let Lulu build up the entire kiln roof. He specifically asked Lu Er Niang to open a small opening.
Yang Cheng planned to make a chimney on this small opening.
Yang Cheng thought of the reason why the success rate of pottery was less than half in the previous earthen kilns. In addition to thermal expansion and contraction, it was also because the flames inside were not fully burned and the gas exchange was insufficient.
Several small holes cannot completely discharge the gas inside, which will cause the pottery to break suddenly when the kiln is opened.
The method of making a chimney is also very simple.
Just like when building the kiln wall, just take the thin mud and slowly circle it upward from the small opening left.
A key point in making a chimney is that the contact point between the chimney and the kiln roof must be close.
Regarding this, Yang Cheng said he was not worried.
If it were in the past, Yang Cheng might have added some straw, some salt or something like this to this place.
And now.
Yang Cheng patted the head of the mud cow next to him and said, "Spit!"
"Moo..."
The Niu Niu screamed feebly, then fell to the ground, gasping for air. It seemed that he was breathing out more and taking in less air.
No matter how much love you have, there is not a drop of it left.
"Hey, you stupid cow, I've eaten so many wild fruits for you, why are you telling me that you don't have any anymore?"
Yang Cheng was an unscrupulous boss, as if he was exploiting employees who had worked overtime for ten and a half days without going home. He pointed at the fruit shells on the ground and said viciously: "Spit me up quickly. If you don't vomit, believe it or not, I will let you go." Someone steps on your belly?!”
"Moo!"
After hearing this, Xini Niu seemed to have thought of something bad, and immediately stood up and spit out several mouthfuls of mud.
"Moo..."
After vomiting the mud, the mud cow looked at Yang Cheng with a flattering look.
"Come on, I don't know you yet, you silly, lazy cow."
Yang Cheng didn't want to do this.
This guy, Xi Ni Niu, is a good boy, but one thing is that he is very lazy and will lie on the ground after walking a few steps and complaining that he is tired.
Vomiting this bit of mud is nothing to it.
I really want to vomit out all the mud in my stomach. This stupid cow's face will turn pale. How can it be like now, with a glowing face, which looks like it's fake at first glance.
With the mud, things will be easier to handle later.
Lulu still followed the method of building a kiln wall, first using thin mud to build up the joints, and then using mud to build up the walls in circles.
The chimney is not too high, less than one meter long.
This earthen kiln is used to burn pottery, not high-grade steel, and does not require a chimney that is too high.
After the chimney was built, Yang Cheng still transformed into a "flame thrower" and used flame magic to speed up the drying and solidification of the chimney.
After all, it's winter, and it's snowing again. Just relying on the sun, I don't know how long it will last.
