They discovered that there was no longer a desolate desert in front of them, but a large grassland with large yellow bearded grass.

This discovery made everyone feel refreshed and they seemed very happy.

Where there are plants, there are a large number of prey. This is the consensus of everyone and the truth they understand after many migrations.

To be more scientifically speaking, where there are many plants, the biological groups involved in the biological chain are even larger.

Wang Yang was also very happy, at least he could eat some fresh animals during the next period.

Not only that, this place is the intersection of two streams. The gurgling water washed away the yellow mud on the shore, forming a river more than eight meters wide.

The river is one meter deep, and in some places it can reach three meters. The bottom of the river is soft sand and looks a bit turbid.

Wang Yang looked up at the dim sky, got off the "grass mud horse" and took them to the edge of the grassland.

The alpacas were happily eating fresh forage.

Wang Yang smiled slightly. These idiots are really heartless and not afraid of anything.

The big-bearded miraculous grasses grow very vigorously, some reaching a height of about one meter and two, and even the adults are only one head taller. You can imagine the difficulty of the ancient apes back then being forced to stand up straight by this dense grassland.

He came to the river, picked up the cold river water and washed his face, took a few more sips, and then threw away a slightly rotten animal skin bag next to him.

It is a very unwise move to put water in bags of animal skins. Water is very easy to breed bacteria and erode animal skins.

I made such a mistake on the road. At that time, I saw the stream getting smaller and smaller, and I was worried that the stream would break, so I filled more than a dozen bags of water. As a result, after more than ten days, the animal skin bag rotted and I didn’t dare to drink the water.

Fortunately, the stream was not broken, otherwise Wang Yang would not have to refine the tin powder into water-filling tools such as tin pots.

Xiaohong came to Wang Yang, pointed at the group of pregnant women behind him, and asked him if he needed to stop.

Wang Yang turned his head and found that the pregnant women were almost at the point of delivery, and they all had big belly and it was very hard to get off the road.

"Stop it first."

Seeing the grassland, Wang Yang felt confident and no longer rushed. He had to ensure the birth of the newborn to avoid unnecessary death.

The adults began to catch fishing, and many adults were preparing to go deep into the grassland to catch their prey.

The vastness of the grassland gives a series of long-range tools such as spear caster and stone casting cables, which can be very useful.

Wang Yang led a group of friends to harvest the bearded grass for fire.

At night, everyone was far away from the grassland and started a fire.

This is what Wang Yang specifically stated, don’t bring fire into the grassland, he doesn’t want to cause wildfire to spread.

And it is not clear what ancient beasts are in the grassland, it is very adventurous to get too close.

In the next month, newborns were born one after another. This time, there were a lot of births, more than twenty, and the number of fifty or sixty people suddenly exceeded eighty. Everyone was very happy.

And on this day, it suddenly started to rain heavily.

Wang Yang was speechlessly beaten into a chicken by the heavy rain, and he couldn't even find a big tree to hide. Fortunately, the weather was hot and the rain was very refreshing when hitting his body, so he was not afraid of catching a cold.

Afterwards, Wang Yang took off the fur on his body, wringed it dry, and then placed it next to the fire to ensure that the fur does not rot quickly in this environment.

The rain comes and the sky is clear.

All the newborns have been born, and the heavy rain has passed a few days ago. The ground has become dry again. Wang Yang is ready to go back to the road and continue moving forward.

He waved to everyone and shouted loudly, asking them all to come.

In the distance, everyone ran over.

Wang Yang began to count the number of people, "One, two, three..."

He counted and frowned after a while. Why were there a few people missing?

He asked everyone about the others? Where are they?

An adult said that they were playing in a big pit in front of them.

Looking along his pointing, sure enough, a few balls of mud flew out from the horizon dozens of meters away.

Everyone began to call them hard.

Hearing the sound, several friends quickly climbed out of the pit and ran towards here covered in mud.

Their faces and bodies were covered with mud, which showed how happy the mud was having.

When they got closer, Wang Yang walked forward and planned to scold them. He was going to enter the grassland next, dozens of meters enough for them to get lost.

But when his eyes just fell on the people, he was completely attracted by the soil on their bodies.

The soil was light yellow, and it was applied to the body, sticking to their skin and hair tightly. It stretched out its fingers and wiped it a little. It was a thigh of two fingers, very thin, soft, and very sticky.

A strange flashed in Wang Yang's eyes. He pulled some hay, lit it, and slowly approached his fingers that were stained with wet mud.

When your fingers feel very hot, use them to cool them down, and then lean over again.

After circulating this several times, the surface of the soil began to harden and it felt very smooth and hard to touch.

The most interesting thing is that the soil did not fall off the fingertips, as if it was biting its finger tightly and refused to leave.

"Clay! It's indeed clay!" Wang Yang's eyes lit up, and he laughed loudly, and he was very happy.

As we all know, clay is the main material for making ceramics, bricks, tiles, and cement. With it, you can build houses, make dishes and other tools. Of course, these are not the main ones.

Wang Yang's experience told him that he could survive without the need for a house, dishes, jars and other tools. At worst, he could suffer from some rain.

And the reason why he was so excited was that he could use clay to build a kiln to refine metals with high melting points, such as iron and copper.

Without a kiln, a bonfire alone cannot reach such a high temperature.

Generally, bonfires are used to refine metals with low melting points, such as tin. If you want to develop a large number of metalware, you have to be kilns.

Wang Yang touched his chin and looked around for a while. He saw everyone's doubts, but did not explain much, and ran directly to the big pit.

Standing by the pit and looking down, you can find that this is a very typical clay pit.

Clay generally exists in several forms, including rock layers in the mountains, yellow sand and rubble, and other forms, and the pit shape in front of you is one of them.

This is not common, I didn't expect to be encountered by myself.

The pit is as big as a basketball court, and it is a small basin. The low part of the pit is accumulated in rainwater and clay, which looks like espresso that has been drunk to the bottom. Perhaps, it is more vivid with melted chocolate.

Everyone also rushed over and asked Wang Yang in confusion.

Wang Yang first used pictures to describe the function of clay to them, drawing cups, dishes, houses and other things.

It took a lot of effort to read and understand it. They knew that this thing had a very strong plastic surname and could fabricate many shapes, but they still didn't understand it very much.

I fully understand that there is only Li Si at present, but Li Si has a doubt.
