"Good question!" Wang Yang gave Li Si a thumbs up, it's good to be able to think, the more you think, the better, and you have to think every day, you have to use it, and you can eat it if you don't think about it.

You must know that the most glorious period of Lu Dao's life was six months before the college entrance examination.

At this time, you know the principle of the operation of celestial bodies, and you know the organic and inorganic reactions, with an elliptical hyperbola in front and a hybrid biosphere in the back.

You can speak English on the outside, you can study ancient Chinese on the inside, you can find the number of columns, and you can speak Ma Zhe.

Tracing back to China for 5,000 years, extending the Chizhou land and sea for millions of years, knowing both music and art computers, and concurrently cultivating martial arts and folk vices.

As soon as the college entrance examination is over, I only know how to play games all night.

Wang Yang has a deep understanding of this, just like now that more than ten years have passed, he only knows how to kill pigs, slaughter cattle and fight tigers, which can be regarded as responding to Chairman Mao, and the intellectual youth went up the mountain.

It would be a hassle for him to explain the changes in the clay now.

He didn't intend to explain, he just picked up a handful of clay and pinched it wildly.

Not to mention, when the clay was wet, it was like plasticine when he was a child, and it was a little childlike, so he made a bowl, put it aside to dry, and then let everyone stop and rest.

After two days, when the surface of the clay was mostly dry and had a little appearance, he began to spread layers of hay, put the bowl in the middle of the hay, and burned it.

Green smoke rose everywhere, the fire roared, only the bowl flickered in the flames, and the gray smoke and faint water vapor rose into the sky together.

The hay burned quickly, and Wang Yang added material from time to time, and it burned all day.

The surface of the bowl is a little more black and dusty, and there is no change in sight.

In the evening, the hay was almost burned. Wang Yang stopped burning.

Everyone watched with him for a few days, but they didn't understand anything. I thought to myself, what is this going to do?

Another day passed, and Wang Yang picked up the bowl. The surface is still a little warm, but it has become very hard.

This is because at high temperatures, the clay changes permanently, and at this point it is no longer soil.

The bowl in Wang Yang's hand is not pottery, not porcelain, not brick, but a semi-finished product that needs to be changed, and the reason is obvious. The temperature is not high enough.

The temperature of firing pottery and porcelain needs to be several hundred degrees larger, several times higher than that of tin, and at that time, it will be a complete change.

And the bowl in his hand is not like four things if it doesn't sound good.

Wang Yang took the "four dissimilarities", put it in the water to wash, wiped off the black ash on the appearance, and then took it out of the water.

It's a bit rough on the surface, and there's no way around it. But it has not been melted away by the washing of water, and it is still hard.

After everyone took it, they realized that the clay had changed dramatically after calcination.

And in order for them to understand the value. Wang Yang filled a small bowl with water, lit the fire, and prepared to cook a casserole to eat.

The water slowly boiled. The minced meat was thrown into the bowl and it didn't take long. The smell of meat came out, and everyone wiped their noses. His eyes lit up, and he realized that it could also cook things, so wouldn't it be better than a tin pot?

Of course, it is better than the tin pot, the melting point of tin is too low, and the temperature of cooking on the fire has to be estimated, in case it is high, the whole pot will be gone.

Clay ceramics can naturally be cooked and eaten, but the heat transfer is so slow that no one likes to do it except in a specific clay pot.

At this moment, everyone exclaimed, alarming Wang Yang.

I saw that in the bowl of boiling water, which was originally clear, there was suddenly a touch of orange, and the orange quickly expanded, confusing the water.

What's going on? Everyone looked at Wang Yang.

Wang Yang was not surprised by this, originally, this is a "four unlikeness", not enough heat, the water seeped into the inside of the bowl along the tiny and fine places, and the places that were not fired turned into clay again.

If the temperature is high enough, some impurities in the clay will melt, all the cracks in the clay will be blocked, and the changes will be completed, and this will never happen.

This was expected by Wang Yang, he was not surprised, making this bowl was just to let everyone understand the role of clay, and it would be used in many places in the future.

Next, Wang Yang rode on an alpaca and left with everyone.

Although it looks good here, Wang Yang will definitely not stay here, he needs clay yes, but he needs dry firewood, otherwise there is clay alone, what is the use of nothing to burn? The hay can't be burned again.

In this way, they continued on their way and entered the Osu Meadow.

……

Under the sun, on horseback, in the dry air, Wang Yang held a piece of hay in his mouth, gently clamped his hunchback, and comfortably browsed the surrounding scenery.

Under the lazy dusk sun, the sun is very comfortable, so comfortable that it is a little intoxicated, and it is a little numb to be drunk.

Smelling the unique smell of grass in the grassland, Wang Yang got off the alpaca and decided to stop here in search of food.

It's been a month since the day I stepped into the grassland.

For a month, they traveled half a day and hunted half a day, and the speed of their march was not very fast.

Because they don't have an abundant source of food, the grasslands look rich, there are still not many animals, and the main food depends on the river.

There are always a lot of fish in the river, but after eating them all the way, the number has also decreased rapidly, and Wang Yang has no choice but to stop.

Needless to say, the osteologist and others went to fish automatically, while Wang Yang and the others went in a team of four or five people, scattering in all directions, looking for food.

The last 20 or so friends, under the protection of more than a dozen adults, harvested the nearby miscanthus grass and prepared the materials for the fire at night.

Wang Yang and the others walked in the grassland, the grass was too lush, and it was everywhere that grew one meter tall, only the head and neck were exposed, and at this height, it was impossible to see the dwarf animals in the distance.

Don't think about small animals, even if there is a leopard, it is basically impossible to find it.

If it weren't for that, it would have been impossible for the crowd to catch their prey.

If you replace this piece of miscanthus with a small miscanthus, the situation will change dramatically.

At this time, Wang Yang was no longer obsessed with finding animals, but focused on whether there were any plants to eat.

He kept his head down, kept his vigilance and attention high, and listened to all directions, ordinary animals could not get close to him, and the little one would give a warning.

Wang Yang saw that it had a good nose and wanted him to help find prey, but the effect was even more unsatisfactory, because the little guy didn't understand his thoughts.

While he was looking, he went to dig up the roots of plants he didn't know to see if there would be any surprises, but unfortunately there were none.

But suddenly, out of the corner of his eye, he saw a familiar plant, the dog's tail grass that he loved to play with when he was a child.

He walked over and suddenly realized that it was not a dog's tail grass, but a ......

"His uncle's wheat?" (To be continued......)
