Under the hay canopy, he flattened the mud one by one to make a small basin in the shape of a square, about two meters long and wide.

According to the idea, he planned to make a larger formwork, but unfortunately the area of the hay canopy was not large enough to make a formwork in the rain.

One template was quickly ready, and he used to smooth out the mud surface in the template as much as possible, then walked to the other hay canopies and moved on to the next one.

The friends obediently automatically gave up the hay canopy and let him work.

There are a total of four templates, each of which is a square of four square meters, the yellow clay surface is very fair, and the uneven places are repaired by Wang Yang.

After that, he began to wait, waiting for the rain to finish and for the yellow mud to dry and take shape.

The rainy season in the savannah is always inexplicable, sometimes it comes and goes quickly, sometimes it is a few days at a time, and the river swells.

Wang Yang and the others didn't wait too long, and the next day, the rain stopped, the temperature rose again, the sun was hot and scorching, and a white mist rose in the grassland, which was very rare.

Standing in the white fog, being swept by the cool cold mist, listening to the chirping of animals in the distance, the sunlight is refracted in the mist, colorful, as if you are in heaven.

The wonderful scenery was glimpsed, the sky was suddenly clear, the golden sun illuminated the world in a dusk, and the hay canopy was torn apart, revealing some muddy stencils on the ground.

The sun was shining all day, the formwork had been fixed, the water inside had evaporated, and in some places it was a little sandy.

Wang Yang asked everyone to pile up hay to make a fire, and then took the tin powder, but as soon as he brought it, he was dumbfounded.

He found. You don't have a heat-resistant container, such as a pot.

There are no heat-resistant containers. So how can tin powder be refined into juice? Even if it is refined into juice, it must not be all over the ground. How do you take it and use it?

At this time, he was depressed, in the past, next to the tin mine, those rocks had grooves of different sizes, and after the tin was turned into sap, it would remain in the grooves, which could be poured into the template to shape.

Now there is yellow earth everywhere, and there are no decent stones, how to use it?

You can't burn it directly in the template, and this method is not impossible. Tin powder is poured into it, a bonfire is lit inside, and as it melts, a flat formwork is cast like a liquid, and then dry wood and charcoal are plucked out of it.

The tin juice refined in this way will have a small amount of ash, which is not pure enough.

It's nothing, it's okay at all.

But the problem is that they don't have dry firewood now, and there are no trees nearby. If you burn it with hay, then the ashes are not ordinary, it is estimated that seven parts of ash and three points of tin.

As long as you are not stupid, you know that this method will not work.

Scratched his head. Wang Yang was worried, thinking about what he had seen and heard in his previous life, and racking his brains to think of a way.

Suddenly. He thought of a possibility.

So without saying a word, he poured the tin powder into a template. Lay it out.

Then a flame was lit next to the formwork.

"Bring the stones!" He shouted at Xiaohong.

Do they have stones? Yes, but it is mainly round pebbles. When they first used the slings as a means of attack, they were highly respected by Wang Yang, because the round stones were less resistant to the wind and could be thrown farther, causing more serious internal injuries.

This was confirmed by numerous hunting expeditions that followed, so they brought many pebbles with them as ammunition.

Red brought the stones, and he asked the other adults equipped with slings to bring them, and threw them into the fire to wait for them to be heated.

What is he going to do? Probably, the average person would think that he wanted to heat the stone and then chisel out the grooves.

But in reality, this is not the case, and I have never heard of the fact that a stone is easy to chisel out grooves when heated.

What he was going to do was something he had heard.

It is rumored that when the Xia Dynasty was still there, some small villages were very poor and did not have metal utensils to boil water, but there were always some small insects like wires in their streams, and if they did not boil and drink, they would have a stomachache, and some people even lost their lives.

They began to boil water in bamboo tubes, and found that before the water could boil, the bamboo tubes were burned, and they made a mistake.

At this time, an old man proposed to heat the stone and throw it into a bamboo tube to heat the stream water.

They tried suspiciously, but found that they could really boil the water, so the village no longer had to worry about the effects of the insects.

The story sounded like a fable, and Wang Yang wanted to try the method in the fable, using tin as water and trying to refine it with stone.

As the minutes passed, Wang Yang kept adding hay to the fire to keep it strong.

Half an hour later, he estimated that the temperature should be very high, so he took out a piece and threw it into the tin powder, squinting his eyes and watching the changes in the tin seriously.

After the stone was thrown into the tin powder, a little green smoke came out, and the tin powder quickly got on the stone and smeared a layer.

He waited quietly.

Time passed minute by minute, ten seconds later, the tin powder did not change, after one minute, the tin powder did not change, after ten minutes, the tin powder still did not change, and even the white tin after 160 degrees did not appear.

Wang Yang was dumbfounded, a little unwilling, and even threw a bunch of stones into it, waiting quietly, but the green smoke that rose seemed to condense into a grimace with the corners of his mouth slightly upturned, laughing at his wishful thinking.

He was speechless and muttered to himself: "Sure enough, the heat conduction of the stone is too poor, even if there is a temperature, it can't reach that high." But is the parable amusing me? ”

He took a wooden bowl, went to the stream, scooped a ladle of water, and threw a hot stone into it.

"Zizi ......" The stone made an inexplicable sound, and then only a muffled sound, a coo, and a bubble bubble came up.

When bubbles come out, it's not the water that boils, but the stones crack! Cracked in all strips, if not in the water, it must have been a small explosion.

wiped his face and spit out four words with difficulty: "Hot expansion and cold contraction......"

Reaching into the water, he found that it was indeed warmer, but Wang Yang knew that if he wanted to boil the water in this way, he didn't know how many stones and hay needed to be consumed.

Not to mention the tin with a higher refining temperature.

Decisively, he vetoed this method.

He walked around worriedly, not knowing what to do at this time. It's easy to think of something constructive, but it's not usually difficult to do.

The next day. It was raining again, this time heavily. The leakage in the hay canopy was even more fierce, and Wang Yang had no good way to solve it for a while, so he had to see where the rain was leaking, and then put the animal skin on the top of the hay canopy and use it as a tile.

Temporarily alleviating the crisis of rain leakage, Wang Yang still did not relax, he set his sights on the north.

There's a clay mine there.

He wondered if he should bring some clay ore over while everyone had nothing else to do.

Bow your head and groan slightly. Wang Yang decided to do just that.

He could have made a burn-resistant pot stove out of clay and smelted tin.

With this thought, Wang Yang no longer hesitated, called everyone, and told them to go and transport some clay by themselves, take care of the wheat and their friends, and try not to fight with a large number of large animals.

Everyone nodded heavily, Wang Yang stopped talking nonsense, and picked more than a dozen adults, including Xiaohong. Mounted the beast and began to run.

With a goal, they moved much faster than they came, galloping their horses in the storm. After one hot day and rainy day after another, on the twentieth day, I came to the clay mine.

The beasts accompanied them everywhere. I don't feel tired, but rejoice. I enjoyed the breath of freedom.

The clay mine was beaten into soft mud by the rain early on, and it took them half a day to fill it quickly. There were more than thirty animal skin bags full, each weighing hundreds of catties.

"Oh~" The beasts were eating grass on the side, replenishing their energy, and flirting with each other from time to time.

Wang Yang resisted two bags of clay and came to the divine beast with white hair on his lower abdomen, and scolded with a smile: "Idiot, you live so heartlessly, this time you will suffer." ”

The fool blinked wide, looked at himself kindly, spit out thick lips, showed a mouthful of yellow teeth, and leaned into his face, as if he thought that this outing was very good.

"Outing?" The king raised his eyebrows and threw two bags of clay on its back.

"Oooh~" It finally realized that it was not here to play, but to suffer.

Wang Yang rode on it and clamped his legs: "Hurry up!" ”

The other beasts roared away, but the idiot didn't move, and oh oh expressed his dissatisfaction.

Wang Yang pinched again: "Hurry up!" ”

"Oooh~"

"Hey, you little rabbit, you still have a girl's temper." Wang Yang glared at it, thinking that he hadn't used its hair to make clothes yet, so he shook off his temper and pinched it again.

This fool stood still, and turned his head to stare at him, the corners of his mouth cracked, as if to say, what can you do with me?

Wang Yang was really anxious, the people in front of him were almost gone, this idiot was still playing tricks, and he slapped his buttocks.

"Smack!" The slap was crisp and loud, and the idiot took two steps forward and stopped walking.

Wang Yang was in a hurry, and he couldn't care about it so much, so he slapped it on the buttocks, and this idiot finally knew that he was powerful, and ran forward reluctantly.

This time the weight was heavy, and the speed of the divine beasts slowed down a lot, and it took a month to return to the tribe.

After going back and forth, two months have passed, Wang Yang asked everyone about the recent situation, and everyone said that nothing happened.

Wang Yang breathed a sigh of relief, handed over the unloading to the others, and ran into the wheat field himself.

After more than two months of abundant rain irrigation, the wheat grew very fast, and some of the wheat that was planted later was almost catching up with the height planted earlier.

It's just that it seems, how can there be a yellow plant in the middle?

He walked over, plucked one and looked at it carefully, and was speechless for a moment, this is a weed.

Turning his head and looking around, he saw that the green wheat field was full of yellow weeds, many of which were miscanthus grass.

He was speechless, didn't he say that nothing had happened? The weeds are almost waist-high, and nothing has happened yet...... (To be continued......)

PS: I went shopping on the street last night, and when I came back, wow, a book friend voted for thirty-five reminders, and they were all 12,000 updates......

Ahem...... Don't do this kind of crazy move, I really don't have 12,000. If you want to vote, just wait for the weekend to vote for 6,000 words, and I'll add more.
