The next day, the eldest brother did not lead people out hunting after dinner as usual. Instead, he followed Han Cheng, the seven or eight children, and Bo to the river.

Also traveling with them were the witch and other people in the tribe. They were very curious about what good things the Son of God had come up with.

After one night, the mud pieces had dried up a lot and all the water on the surface had disappeared. If you touch them gently with your hands, you can feel that they are much harder than yesterday.

The witch looked at these things with a thoughtful look in his eyes. If these things were really hard enough, they could indeed hold a lot of things. Just as the Son of God said, they were far more useful than stone bowls and stone basins.

But the key point is that this thing is made of mud, how can it be strong?

The witch was very puzzled. Even though he had the knowledge passed down from generation to generation of witches, he couldn't figure out how the Son of God would make these mud things harden.

The witch was very smart. He knew that the mud was not solid, and the Son of God must know that. Since the Son of God knew that and still said and did so, there must be a way that he didn't know to make the mud solid.

"Use fire, burn it."

Han Cheng stated his solution in Mandarin.

But after this method was proposed, Wu and the eldest brother became even more confused, because in their understanding, fire can burn many things!

Shouldn't mud become looser when it is burned by fire? How can it become solid?

There is no way to communicate this, because it is too difficult to explain this series of things!

Han Cheng had no choice but to use the old method and attribute it all to the gods. He did not explain too much himself and let the final results speak for themselves. This way he could save a lot of time and effort.

The eldest brother, who not only did not understand the situation after the visit but became even more confused, led the equally confused people to go hunting. Han Cheng took the little guys in the cave and continued to make clay embryos.

The witch did not go back, but watched Han Cheng and the minors in the tribe playing in the mud.

Watching them make these mud into strange-looking things, after roughly understanding the process, Wu also joined the ranks of playing with mud...

On the third day, the clay embryos made on the first day were half dry. Han Cheng looked at the more than fifty clay embryos placed on the ground and temporarily stopped making clay embryos. Instead, he led these people to collect dead grass, fallen leaves, twigs and other things.

Because it is spring now and the people here don't have the habit of setting fire to the slopes, there is a thick layer of dry grass on the ground.

After hearing that burning things with fire could make them sturdy, these minors have already developed a strong interest in them.

Everyone worked hard and didn't feel tired.

By the afternoon of that day, a large pile of hay and firewood had been piled up nearby.

On the fourth day, the first batch of clay embryos were almost dry. Due to the weather, except for three that had cracks and were useless, the rest were intact. Han Cheng breathed a sigh of relief. It was a good start, right?

Han Cheng threw away the three broken ones and then circled out an area of ​​about two square meters nearby. He had people dig down to a depth of thirty centimeters and then spread a layer of hay on it.

With the help of the eldest brother and others who came to see the wonder, the clay embryos made on the first day were carefully placed on the hay and arranged neatly, leaving a gap of about five centimeters between each clay embryo.

Then, under Han Cheng's demonstration, everyone filled the gaps with the hay and firewood collected yesterday and pressed them firmly with their hands.

Then he broke the dead grass into smaller pieces, mainly the stem-shaped dead grass that was resistant to burning, and covered the mud embryos with them. After covering them about ten centimeters, he tried to compact them with his hands, and then continued to put grass on them. He did not stop until he had covered the jar made by Heiwa, which was more than one meter high, and added more than ten centimeters to it.

At this point, all the pottery was covered with broken grass, leaving no trace.

Just when many people, including Wu, thought that they could start the fire, Han Cheng gave an order that surprised them.

Han Cheng did not order a fire to be lit, but instead asked people to fetch water from the river, wet the loose soil that had just been dug out, and then make mud.

Different from the relatively hard clay used in making clay models, according to Han Cheng's requirements, the mud this time is relatively soft and can be called thin mud.

Well, Heiwa, Zhuang and the others are just trying to smooth things over...

Under the gaze of everyone, Han Cheng picked up the mud and pasted it on the pile of firewood covering the mud mold, from top to bottom, making sure to seal all the firewood wherever he passed until no firewood could be seen from the outside.

After these few days, Heiwa and his friends have become familiar with playing with mud. After Han Cheng's demonstration and orders, they began to learn from Han Cheng and piled mud on the firewood from different angles.

At the bottom of the firewood pile, Han Cheng did not let Heiwa and the others do it, but did it himself.

Four 20-centimeter square gaps were left around the ground, without being sealed with mud.

"Send the fire."

Han Cheng spoke, and without him having to designate anyone, Junior Brother Sha who was watching here had already run towards the cave quickly.

Although he didn't understand why the Son of God did this, he could still feel that something was wrong from this series of orderly steps.

The fire is coming.

Han Cheng took the burning tree trunk from Junior Brother Sha, and moved to the four empty spaces, lighting them one by one.

Because the materials used for filling were specially crushed dead grass and leaves, and they were pressed very hard by hand, so they would not burn quickly, and even open flames would hardly start.

Especially after making sure that the fire would not go out, Han Cheng sealed the four ignition ports with mud, leaving only a small hole with a diameter of less than half a centimeter for ventilation. The flames inside burned even slower.

Han Cheng, feeling relieved, told Wu, his senior brother and everyone else that it would take three days to know the result.

This made everyone who was eager to know the result a little anxious.

But there was no other way, so everyone stayed here for a while. Knowing that there would be no results in a short period of time, the eldest brother took the hunting team out to hunt.

When the glaciers melt in spring, fish are not as easy to catch as in winter, so hunting wild animals becomes the primary source of food for the tribe.

Wu did not go back, but stayed here with Han Cheng and others.

After playing for a while, at Han Cheng's call, a group of underage primitive people began to make clay molds again.

However, unlike their concentration in the past, they seemed a little absent-minded today. From time to time, they would turn their heads to look at the firewood pile covered with mud, expecting the motionless firewood pile to bring something magical soon.

Not to mention them, even Han Cheng would take a look from time to time, and sometimes he would crawl to the ground and look through the small hole to see if the fire inside was out.

After all, this was his first time making pottery and he had only watched the video once, so he had no idea whether he could do it right in one go.
