They found that there was no longer a desolate desert ahead, but a vast grassland of yellow bearded miscanthus grass.

This discovery lifted everyone's spirits and made them seem very happy.

Where there are plants, there is a large number of prey, this is the consensus of everyone, and it is also the truth that they have learned through many migrations.

Scientifically speaking, where there are many plants, the biological chain involves a larger group of organisms.

Wang Yang is also very happy, at least he can eat some fresh animals in the next time.

Not only that, but this place is the intersection of two small streams, and the gurgling water washes the yellow mud on the bank, forming a small river more than eight meters wide.

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

Wang Yang looked up at the dusky sky, got off the "grass and mud horses", and led them to the edge of the grassland.

The alpacas are happily eating fresh forage and are very happy.

Wang Yang smiled slightly, these idiots are really heartless, and they are not afraid of anything.

Those bearded miscanthus grass grows vigorously, some reach a height of about one meter and two, and even the adults are only a head taller, you can imagine that the australopithecus of the year was forced to stand up straight by this dense grassland.

He went to the river, picked up the cold water, washed his face, took a few more sips, and then discarded a somewhat rotting bag of animal skins beside him.

It is very unwise to use bags of animal skins to fill water, as water is very prone to bacterial growth and erosion of animal hides.

I made such a mistake on the road, when I saw that the stream was getting smaller and smaller, and I was worried that the stream would break. So I filled more than a dozen bags of water, and it turned out to be more than ten days later. The skin bag rotted, and the water did not dare to drink.

Fortunately, the stream is not broken. Otherwise, Wang Yang said that he would not be able to re-refine the tin powder into a tin kettle or other water-loading tool.

Xiaohong came to Wang Yang's side, pointed to a group of pregnant women behind him, and asked him if he needed to stop.

Wang Yang turned his head, those pregnant women were almost in labor, and they had a big belly and poop, and it was very hard to catch up.

"Let's stop."

Seeing the grassland, Wang Yang's heart has a bottom, no longer in a hurry, and must ensure the birth of a newborn. so as not to have unnecessary deaths.

The adults began to be busy fishing, and many of them were ready to go deep into the grasslands to catch their prey.

The wide grassland gives a series of long-range tools such as spearthrowers and slings a lot of room to play, which can come in handy.

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

And when evening came, the people were far away from the prairie and made a fire.

This is what Wang Yang specially explained, don't bring fire into the grassland. He didn't want to start a wildfire.

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

Over the next month, newborns were born one after another, and this time there were many births. More than twenty, the number of fifty or sixty people broke through to eighty at once, and everyone was very happy.

And on this day. Suddenly, it rained heavily.

Wang Yang was speechless and was beaten into a soup chicken by the heavy rain, and he couldn't even find a big tree to dodge. Fortunately, the weather was hot, and the rain hit me very refreshingly. I'm not afraid of catching a cold.

Afterwards, Wang Yang took off the fur on his body, wrung it out, and then put it next to the fire to dry to ensure that the fur did not decay quickly in this environment.

Storm.

With all the newborns born, a few days after the heavy rain and the ground drying out again, Wang Yang was ready to get back on the road and move on.

He waved his hand at the crowd and shouted for them all to come.

In the distance, everyone came running.

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

He counted, counted, and frowned after a while, why were there fewer people?

He asked the crowd what about the others? Where are they?

Some adults said they were playing in a big pit in front of them.

Following his point, sure enough, a few clouds of mud flew out on the horizon dozens of meters away.

The crowd began to call out to them vigorously.

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

Their faces and bodies were covered with mud, which showed how much fun the mud was playing.

When they got closer, Wang Yang stepped forward, intending to reprimand them, but then they were going to enter the grassland, and a few dozen meters was enough for them to get lost.

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

The soil was pale yellow, smeared on their bodies, sticking to their skin and hair, stretched out their fingers and wiped them a little, two fingers together, very thin, very soft, very sticky.

Wang Yang's eyes flashed with strangeness, and he pulled some hay casually, lit it, and slowly approached his fingers stained with wet mud.

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

After a few cycles like this, the surface of the soil begins to harden and is smooth and hard to the touch.

The most interesting thing is that the soil does not fall off the fingertips, as if biting the fingers and refusing to leave.

"Clay! Sure enough, it's clay! Wang Yang's eyes lit up, and he smiled, very happy.

As we all know, clay is the main material for making ceramics, bricks, cement, with which it is possible to build houses, make utensils such as dishes, of course, these are not the main ones.

Wang Yang's experience taught him that he could survive without tools such as houses, dishes, jars, etc., and it was a big deal to suffer a little sun and rain.

He was so excited because he could build a kiln out of clay to make metals with high melting points, such as iron and copper.

Without a kiln, a campfire alone would not have been able to reach that high temperature.

The general bonfire is also used to smelt tin, a metal with a low melting point, and if you want to develop a large number of metal tools, you have to use a kiln.

Wang Yang touched his chin, looked around, saw everyone's doubts, and didn't explain much, and ran directly to the big pit.

Standing on the edge of the pit and looking down, you can see that this is a very typical clay pit.

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

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

The pit is the size of a basketball court, and it is a small basin, and the lower part of the pit in the rainwater accumulation, with the clay, looks like drinking espresso to the bottom, perhaps, with melted chocolate.

Everyone also rushed over and asked Wang Yang in confusion.

Wang Yang first used pictures to depict the role of clay, drawing cups, dishes, houses and the like.

It took them a lot of effort to understand what they knew, and they knew that this thing was extremely malleable and could fabricate many shapes, but they still didn't understand it very well.

Completely understood, there is only Li Si at present, but Li Si has a doubt.

Since clay turns into mud when it touches water, what's the use of the things that are made? Isn't it all over when it rains? (To be continued......)

PS: It's a holiday today.,There's an update.,It's estimated that it will come out in the evening.
