The explanation of the bark made Kong Er even more confused, the cube-shaped pottery, what is this, the pottery can also build a wall, so it won't be kicked down by someone?

The more Kong Er thought about it, the more he was forced to become, and he didn't understand what the use of this was at all.

Looking at Kong Er's blank expression, Wang Lang smiled and said: "Don't think about it, you will understand when the time comes, you can open the kiln tomorrow, there is still a lot of work to do, hurry up and rest!" ”

The two left Wang Lang's place, and Kong Er returned to his house with a confused face.

When Kong Er's wife saw her husband coming back, she got up and greeted her, saying, "Have you finished talking to the chief?" ”

Kong Er nodded and said, "It's over!" ”

"By the way, how are you feeling these days, you are also pregnant, you usually have to pay more attention, now it is different, men can also watch their children grow up, I don't want anything to happen to my child." Kong Er looked at his wife's slightly bulging lower abdomen and said.

"I know this, and the leader didn't let me do any heavy work, so he cooked for the clansmen and cleaned up the tribe's sundries, you can rest assured." The forest leaf insect said slowly.

"That's good! Rest early, I'm tired from the journey. Kong Eryi sat on the straw mat and said with a sigh.

Lin Ye Worm smiled: "You are still tired, let me tell you, the talents in the tribe are tired these days, you have to rest well, and you will have to build a dam in a few days, there will be times when you are tired." ”

Hearing another word in his wife's mouth that he didn't understand, Kong Er was a little confused, how long he had been gone, there were so many changes, if he had been away for a long time, he probably wouldn't know this tribe.

Kong Er didn't ask what the embankment was, now he didn't bother to ask, he could do whatever he wanted when the time came, and it didn't take long after he lay down to hear a burst of snoring.

The next day, it was time to open the kiln to inspect the brick firing, as for what color of bricks can be fired Wang Lang is not clear, in his memory, he has seen only two kinds of bricks: red bricks and green bricks, and he basically knows nothing about the difference.

Everyone in the tribe gathered around the brick kiln, wanting to see what could be burned after so many busy days.

The two soldiers knocked a small hole in the entrance of the brick kiln with a wooden stick, and put their palms on the small hole to feel the temperature.

"Chief, there's still a little heat in here, but it's not hot." A soldier said to Wang Lang.

Wang Lang nodded and said, "Open the kiln!" ”

When the soldier heard this, he waved a wooden stick to knock down the hole where the earth had been sealed, and the mud fell to the ground with a rumbling sound, raising a large cloud of dust, and when the smoke dispersed, the black hole in the brick kiln appeared in front of the people.

After leaving the smell for about half an hour, Wang Lang walked into the brick kiln with a torch.

The firelight illuminates the situation in the cave, a stack of turns is neatly stacked in the brick kiln, and some broken bricks have fallen on the ground, Wang Lang picked up a brick, there is still some residual temperature on it, although there is a firelight, but still can't see the color of the brick.

Walking out of the brick kiln with a brick, the onlookers suddenly came over.

Looking at the black thing in Wang Lang's hand, Kong Er asked, "Chief, is this a brick?" ”

Wang Lang nodded, this brick has a black appearance, it is obviously smoked like this, in his impression, he has never heard of black bricks, and it is impossible for him to make a new variety.

The dagger scraped off a piece of the brick's black exterior, revealing the brick's original appearance, and the reddish-brown surface looked very similar to that of another world.

Wang Lang smiled inadvertently, he knew that he had basically succeeded this time, and there was nothing wrong with his appearance, but after all, bricks are building materials, and whether they are qualified or not depends on their hardness.

"Bring me an axe." Wang Lang said to the people around him.

After a while, the axe was delivered, and Wang Lang put the brick on the ground, raised the axe, and smashed it against the brick with the blunt side of the axe, but he didn't use much force.

"Dang!" The whole body is clear.

Seeing this, Wang Lang raised the axe again, this time using all his strength, slammed down, and the brick broke in response.

The onlookers were amazed, they participated in the whole process of making bricks, knew every step, originally thought that only things were the same as pottery, they were made of mud, but the effect was completely different, and the hardness was more than many times stronger than pottery.

In fact, the brick itself can be regarded as pottery, but the brick is too thick, so it is much stronger than the pottery.

Wang Lang looked at the broken bricks and frowned, this quality is more than twice as bad as the bricks used in the other world, but it is barely enough for him now.

"Lang, why is this brick so hard?" Starry stared at the broken bricks and said in surprise.

"You don't look at how thick it is, but if you make a clay pot so thick, it's not much worse than this." Wang Lang said.

After Wang Lang said this, everyone suddenly realized, and sighed that they didn't think of such a simple truth.

The hardness of the bricks is barely qualified, but it still needs to go through another test, the bricks are to be exposed to the outside for a long time, and the erosion of rain is inevitable, and if you want to put it into use, you must try it with water.

Wang Lang took the fragments of the bricks, threw them into a clay pot filled with water and began to soak them.

After waiting for nearly twenty minutes in boredom, Wang Lang took out the broken bricks, and the surface of the bricks was naturally all wet, Wang Lang smashed the bricks open with an axe, and saw that the bricks were only wet on the surface, and the inside was still dry, which meant that the bricks could be used.

Wang Lang's series of actions made everyone look at them in a fog, and they didn't know what they were doing with this smashing and soaking.

"Chief, what's next?" Bark asked.

"No, this brick is not bad, it can be used, move all the bricks in the brick kiln!" Wang Lang said.

The bark let out an "oh", scratched his head, and went to the brick kiln with the others to move the bricks.

After half a day, after all the bricks from this kiln were removed, only a small part of them were blackened, most of them were reddish-brown bricks, which were neatly stacked together, and there were some broken bricks next to this pile of bricks.

Firing bricks is the same as making pottery, it is inevitable that there will be damage, Wang Lang estimated, the damage rate of this kiln is about 10%, such a result can barely accept.

Broken bricks are not completely useless, mixing them in the soil, using them to build walls can also play a role in reinforcing the wall, now that the tribe lacks everything, Wang Lang does not want to produce too much waste, and makes the best use of it as much as possible.
