Chapter 243: Primitive Cement Appears!
The Beast-eared Girls and Winged Girls were stunned for a moment after hearing this.
Then they all started laughing happily.
Next, the Beast-eared Girls and Winged Girls all turned and walked towards the cave.
They took various tools and headed back to the clay pit.
Meanwhile, Lin Ye began digging more pottery kilns.
Lin Ye felt that ten pottery kilns were still a bit too few.
He continued digging until evening.
Beside the ten pottery kilns, another ten identical pottery kilns were added.
After dinner,
the Beast-eared Girls and Winged Girls fell asleep as soon as they lay down on their beds.
For the next few days,
everyone was busy digging clay.
Mixing mud to make unfired bricks.
Then it was time to fire the bricks.
During this time, Sakura’s talent ability was strengthened again.
Now Sakura’s talent ability could directly cover all the crops in the vegetable garden.
After a few days like this,
not only the wheat,
but also the grapes and jujube trees grew very well.
The Beast-eared Girls and Winged Girls were becoming more and more skilled at making bricks.
And they basically made no mistakes anymore.
Lin Ye let them make bricks on their own.
He, on the other hand, dug out a pottery kiln close to the ground, much shorter than the others.
Moreover, this pottery kiln was cone-shaped, narrow at the top and wide at the bottom.
There was another essential item needed to build brick kilns and furnaces.
That was an adhesive.
Initially, the primitive adhesive was clay.
But after being baked and then rained on, it would quickly be washed away.
Then the pottery kilns and furnaces would collapse.
Later, people discovered glutinous rice.
By adding glutinous rice juice to the clay and stirring it evenly,
this clay would become an adhesive comparable to cement.
It would not change for decades or even hundreds of years.
However, Lin Ye did not have glutinous rice on hand.
He could not make an adhesive comparable to cement.
Therefore, Lin Ye decided to make primitive cement directly.
After finishing the construction of the uniquely shaped pottery kiln,
the unicorn pulled the carriage, crossed the bridge, and arrived on the other side of the river.
Lin Ye sat in the carriage and had the unicorn continue downstream.
The first time he crossed the river to this side,
Lin Ye discovered that a large area of eucalyptus trees grew here.
Over many years,
the ground had accumulated nearly half a meter of dry eucalyptus bark.
This was the material Lin Ye needed to make cement.
After finding a suitable place,
Lin Ye filled the carriage with eucalyptus bark.
He returned to the tribe.
The Beast-eared Girls and Winged Girls were still busy making unfired bricks.
The twenty pottery kilns were now just enough to fire the unfired bricks made by the Beast-eared Girls and Winged Girls in one day.
The next day, after taking the bricks out of the pottery kiln,
they could directly put in the unfired bricks made the previous day for firing.
This way, they could produce over three hundred bricks per day.
When Lin Ye returned to the tribe with the eucalyptus bark,
the unicorn brought the carriage to the pottery kilns.
Lin Ye unhitched the unicorn.
Then he began to make primitive cement.
He unloaded a large amount of eucalyptus bark from the carriage.
He directly filled the cone-shaped pottery kiln with it.
Until it was completely full,
Lin Ye borrowed some fire from the pottery kiln that was currently firing bricks.
He ignited the eucalyptus bark in the cone-shaped pottery kiln.
This eucalyptus bark was very dry, already brittle.
So it burned very quickly in the cone-shaped pottery kiln.
Flames continuously spewed out from the small holes at the top.
Lin Ye continuously added eucalyptus bark to the cone-shaped pottery kiln.
The entire carriage filled with eucalyptus bark.
Lin Ye burned until evening before he finished.
The pottery kiln had even turned a little red from the heat.
The Beast-eared Girls stopped their work when they saw the sun setting.
Seeing that Lin Ye was busy with something, they came over to take a look.
At this time, Lin Ye had already put the last few pieces of eucalyptus bark into the cone-shaped pottery kiln.
The Beast-eared Girls watched for a while with doubt.
Then they lost interest.
They went to the water pipe to wash their hands.
Lin Ye saw that the fire still needed to burn for a while.
So he also walked towards the water pipe.
The ground in front of the water pipe was dug up for wet mud to build the kiln and fire bricks,
so there was already a large pit here now.
The pit was now filled with water.
The Beast-eared Girls and Winged Girls squatted beside the pit to wash their hands.
Because the ground around here was covered with water and mud,
the Beast-eared Girls’ tails were all held high up.
Lin Ye looked at this scene from behind and couldn’t help but want to play with them.
However, he knew that for some reason, whenever their tails were grabbed, they would lose all their strength and become boneless.
Lin Ye was afraid they would fall into the water pit.
However, looking at this place, Lin Ye had an idea.
Since they now had both bricks and cement,
perhaps he could dig a swimming pool here later!
Lin Ye imagined playing with the Beast-eared Girls and Winged Girls in the swimming pool in the future.
He immediately decided.
He must dig this swimming pool.
Not only could they play, but he could also teach the Beast-eared Girls and Winged Girls how to swim.
Lin Ye also walked to the side and washed his hands.
Then he went back to the open space to start a fire and cook.
Since they had started busying themselves with firing bricks,
the Beast-eared Girls’ eyes had been sparkling every day.
Every step they took, they knew what they were going to do.
Unlike before,
when they didn’t know what to do each day and wandered aimlessly in the tribe.
They would even rush to do any chores available.
Time moved on to the next day.
The Beast-eared Girls and Winged Girls continued to fire bricks and make unfired bricks.
Lin Ye, however, arrived at the cone-shaped pottery kiln early.
After the eucalyptus bark had burned,
it left a lot of white powder in the pottery kiln.
Lin Ye took several wooden buckets and filled each one with half a bucket of water.
He carefully scooped the ash left from burning the eucalyptus bark into the wooden buckets.
The eucalyptus bark ash slowly sank in the wooden buckets.
Finally, all sorts of impurities remained on the surface of the water.
After putting all the eucalyptus bark ash into separate wooden buckets,
and waiting for them to settle for a while,
Lin Ye poured out the excess water from the buckets.
The eucalyptus bark ash had now turned into something like plaster in the water.
Lin Ye dug them all out of the wooden buckets.
He shaped them into small white balls with his hands and placed them aside.
Then he started a fire again in the cone-shaped pottery kiln.
Lin Ye waited for the flames to burn for a while.
Using two branches to clip them, he put these small white balls into the fire one by one.
After putting them all in,
Lin Ye took the wooden buckets to the water pipe and drew a few buckets of water.
After returning,
he immediately took the branches and removed the small white balls that had just been placed in the fire.
After taking them out, Lin Ye directly threw them into the water.
As soon as the small white balls entered the water, they bubbled profusely.
They quickly disintegrated themselves, turning back into a plaster-like substance.
Lin Ye showed a satisfied smile upon seeing this.
Then he sped up.
He placed the small white balls into the wooden buckets one by one.
With a smile on his face, Lin Ye used a long wooden stick to continuously stir the white precipitate in the bucket.
When it was almost done,
Lin Ye reached in and scooped out a little.
He added some dry clay and water.
He mixed them together.
Soon, Lin Ye obtained a small mud ball.
He rolled it into a small ball and placed it aside.
Lin Ye began to pour out the water from the wooden buckets, scoop out all the precipitate, and place it on the stones to dry.
This eucalyptus bark ash.
After Lin Ye’s series of operations,
it had already become an excellent adhesive.
Combined with clay, it was the most primitive version of cement.
After Lin Ye finished everything,
the small ball he had made earlier had also solidified.
Lin Ye smashed it twice on the stone with his hand. “Clang! Clang!”
Listening to the sound of hard objects striking,
Lin Ye looked at the small ball in his hand with a smile.
Then he threw the small ball back into the water.
After entering the water, the small ball
bubbled a few times and then became still.
After a while, Lin Ye took the small ball out. “Clang! Clang!”
He knocked it on the stone again twice.
The sound produced was indistinguishable from before.
This made Lin Ye’s smile even more pronounced.
At this moment, Sakura returned after finishing her talent ability on the crops in the vegetable garden.
Seeing Lin Ye smiling so happily,
she bared her teeth and ran to Lin Ye’s side, blinking her eyes and asking.
“Ye, what did you make again? Why are you so happy?”
“Wow, what are these? Why are they whiter than flour?” Sakura had just finished asking Lin Ye.
Then she saw the white eucalyptus bark ash drying on the stones nearby.
