He spread the mud one by one under the hay canopy to make a small square-shaped basin. The length and width should be about two meters.

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

A template was quickly completed. He spread the mud in the template as smooth as possible, then walked to other hay tents and continued to the next one.

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

There are four templates in total, each of which is a square of four square meters. The yellow clay surface is very fair, and the areas with holes have been smoothed by Wang Yang.

After that, he began to wait for the rain to stop 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, and sometimes it lasts for several days, causing the river water to swell.

Wang Yang and others did not wait too long. On the second day, the rain stopped, the temperature rose again, the sun was hot and fierce, and white mist rose from the grassland, which was very rare.

Standing in the white fog, being hit by the cool cold mist, listening to the chirping of animals in the distance, the sunlight refracting in the mist, making it colorful, it feels like you are in heaven.

A glimpse of the wonderful scenery suddenly occurred. The sky was suddenly clear and the golden sun illuminated the world dimly. The hay tent was opened, revealing some muddy templates on the ground.

The sun has been shining all day, the template has been fixed, the water inside has evaporated, and some places have become a little deserted.

Wang Yang asked everyone to pile hay to light the fire, and then fetched the tin powder, but as soon as he fetched it, he was dumbfounded.

He found that he did not have a heat-resistant container, such as a pot.

If there is no heat-resistant container, how can the tin powder be refined into juice? Even if it is refined into juice, it still has to be spread all over the floor, so how can it be used?

At this time, he was depressed. In the past, the rocks next to the tin mine had grooves of different sizes. After the tin turned into juice, it would stay in the grooves and could be poured into the template to form.

Now there is yellow earth everywhere and no decent stones. How to use it?

You can't burn it directly in the template. This method is not impossible. Pour the tin powder into it and raise a bonfire inside. As it melts, it will cast into a flat template like a liquid, and then put dry firewood and charcoal in it.

come out.

The tin juice produced in this way will contain a small amount of ash and is not pure enough.

It's nothing, it doesn't matter.

But the problem is that they have no dry firewood now, and there are no trees nearby. If they use hay to burn it, the ashes will be extraordinary. It is estimated that 70% ashes and 30% tin.

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

After scratching his head, Wang Yang felt worried, thinking about what he had seen and heard in his previous life, racking his brains to think of a solution.

Suddenly, he thought of a possibility.

So without saying a word, he poured the tin powder into a template and spread it flat.

Then a flame was lit next to the template.

"Bring the rocks!" He shouted to Xiao Hong.

Do they have stones? Yes, they are mainly round pebbles. When they used slings as a means of attack, they were highly praised by Wang Yang because round stones suffered less wind resistance and could be thrown farther.

Far away, causing more serious internal injuries.

This was confirmed in countless subsequent hunting activities, so they brought many pebbles as ammunition.

Xiaohong brought the stones, and he asked other adults equipped with slings to bring the stones, and then threw them into the fire one after another, waiting to be heated.

What does he plan to do? Most people may think that he wants to heat the stone and then carve out grooves.

But in fact, this is absolutely not the case. I have never heard of the fact that grooves can be easily carved out of stone when heated.

What he planned to do came from something he heard.

Rumor has it that during the Xia Dynasty, some small villages were very poor and did not have metal utensils to boil water, but there were always small wire-like insects in their ditches. If they were not boiled and drank, they would cause stomach ache, and some people even threw them away.

Little life.

They started to boil water in a bamboo tube, but found that the bamboo tube was burned before the water boiled. They were in trouble.

At this time, an old man suggested heating the stones and throwing them into bamboo tubes to heat the stream water.

They tried it suspiciously and found that it could indeed boil water, so the village no longer had to worry about the influence of insects.

This story sounded like a fable, so Wang Yang wanted to try the method in the fable, treating tin as water and trying to refine it with stones.

As time 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, threw it into the tin powder, and squinted his eyes to carefully watch the changes in the tin.

After the stone was thrown into the tin powder, a little bit of green smoke came out. The tin powder quickly stained the stone and smeared it with a layer.

He waited quietly.

Time passed minute by second, and after ten seconds, 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. Even the white tin after 160 degrees did not appear.

Wang Yang was dumbfounded and a little unwilling. He threw a bunch of stones in and waited quietly, but the rising smoke seemed to condense into a grimace with slightly raised corners, mocking his wishful thinking.

He was speechless and murmured to himself: "Sure enough, the thermal conductivity of stone is too poor. Even if it has a temperature, it cannot reach that high. But, is that fable just to make me laugh?"

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

"Zizzi..." The stone made an inexplicable sound, and then there was only a muffled sound, a pop, and a bubble popped up.

When bubbles come out, it's not that the water has boiled, but that the stone has cracked! It's broken into pieces. If it wasn't in the water, it must have been a small explosion.

He wiped his face and uttered four words with difficulty: "Heat expands and contracts with cold..."

Putting his hand 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 would be consumed.

Not to mention tin which has a higher refining temperature.

Decisively, he rejected this method.

He walked around worriedly, not knowing what to do at this time. It was easy to think of anything with the surname of construction, but it was not that difficult to do it.

The next day, it rained again, this time it was heavy rain, and the leakage in the hay canopy was even worse. Wang Yang had no good solution for the moment, so he had to look at where the rain was leaking, and then put the animal skin on the hay.

The top of the tent is used as a tile.

The crisis of rain leakage was temporarily alleviated, but Wang Yang still did not relax and set his sights on the north.

There is a clay mine there.

He was wondering whether he should take advantage of the time when everyone had nothing to do to transport some clay ore.

After lowering his head and thinking for a moment, Wang Yang decided to just do it.

He could have used clay to make a fire-resistant pot and then smelted tin.

With this idea in mind, Wang Yang no longer hesitated and called everyone over, telling them to transport some clay, watch the wheat and his friends, and try not to fight with the huge number of large animals.

Everyone nodded solemnly, Wang Yang stopped talking nonsense, picked a dozen adults including Xiao Hong, mounted the mythical beast, and started running wildly.

With the goal in mind, they moved forward much faster than when they arrived. They galloped their horses in the storm and experienced one cool and rainy day after another. On the twentieth day, they arrived at the clay mine.

The mythical beasts accompanied them everywhere, and they did not feel tired. Instead, they were happy and enjoying the breath of love.

The clay mine had been beaten into soft mud by the rain early. They spent half a day quickly filling more than 30 full animal skin bags, each weighing several hundred kilograms.

"Oh~" The mythical beasts were eating grass on the side, replenishing their energy, and exchanging a few words from time to time.

Wang Yang carried two bags of clay and came to the mythical beast with white hair on its lower abdomen. He laughed and cursed: "Idiot, you live so heartlessly, you will suffer this time."

The idiot blinked his big eyes, looked at himself kindly, put out his thick lips, exposed his yellow teeth, and put his face together, as if he thought this outing was very good.

"Outing?" Wang Yang raised his eyebrows and threw two bags of clay onto its back.

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

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

The other beasts left with a bang, but this idiot didn't move, expressing his dissatisfaction.

Wang Yang clamped again: "Quickly go!"

"Oh~"

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

This idiot stood still, turned his head and glared at himself, and cracked the corner of his mouth, as if to say, what can you do to me?

Wang Yang was so anxious that the people in front of him were almost gone. This idiot was still playing tricks, just slapping it in the chest.

"Pah!" The slap was loud and clear. The idiot took two steps forward but stopped moving.

Wang Yang was so anxious that he didn't care about it anymore, so he slapped it hard on the chest. The idiot finally realized how powerful it was and ran forward unwillingly.

This time the weight was very heavy, and the speed of the mythical beasts was much slower. It took a month to return to the tribe.

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

Wang Yang breathed a sigh of relief, left the unloading work to others, and ran to the wheat field.

After more than two months of abundant rain irrigation, the wheat grew very fast. Some of the wheat planted later almost caught up with the height of the wheat planted earlier.

But it seems, why are there yellow plants in the middle?

He walked over, pulled out one and looked at it carefully, and was speechless. It was a weed.

I turned around and looked around, and saw that among the green wheat fields, there were yellow weeds everywhere, many of which were miscanthus.
Chapter completed!
