Wang Yang put down Wang Yingying and quickly summoned everyone. Without saying a word, he took them to the other side of the hillside, pointing to the dug out ore layer and shouting "whimper"...

Then he drew his own discoveries from them.

Everyone was very excited and said nothing and digged directly.

It took more than ten days to do this. All the shallow soil layers on the hillside were dug up, revealing large ore layers. Everyone spared no effort to mine them wildly, during the day and at night, and still in their dreams.

In short, the faster you can pick it, and you will almost enter a state of madness.

The mining process is not fast. Everyone has limited manpower and tools. It takes a lot of effort to mine a pile of hard ore layers, but this does not hit their passion and work hard.

A month later, the small hill was mined by everyone, and it was really the tip of the iceberg, and it was needless to estimate.

The energy and effort they spent in January were completely different from the gains, and everyone felt a little disappointed.

Wang Yang's original plan was to get as much tin as possible before winter arrived, and then migrate again.

But at present, even if it is mined for another three months, this small hill will not be mined, let alone the large amount of tin ore that may be found underground.

Since it cannot be mined, should you store food and deal with the arrival of winter?

To be honest, he didn't want to stay here because he didn't know whether the ice age would expand here. Staying here is not safe. Maybe he can be stable for one or two years, but in the long run, it is not a good plan.

He still needs a more stable living environment, and migration is a matter of time sooner or later.

Just how to solve the current situation where tin mining is too slow?

He looked at the heated ore in the bonfire and remained silent.

The amount of tin acquisition is very low, and these ores do not have much tin. Now they have only refined dozens of kilograms of tin ore. Half a wooden barrel is not large in size and is quite rare.

The extraction of tin is also a big problem, and he found that there is a difficulty in extracting tin. After the tin is melted, it will often be mixed with charcoal and firewood, mixed with a lot of impurities. It is difficult to achieve all the tin in a piece of ore.

He must think of a better way and use a better way.

The firelight reflected Wang Yang's face, his brows frowned, and Wang Yingying brought him food and fruit.

After taking a few bites, Wang Yang summoned everyone to explain their future plans.

"Stop here first, don't migrate this year, store more food and study tin."

He proposed four very clear and concise ideas, which received support from everyone.

But they don’t understand the fourth point “studying tin” very much, and have never been exposed to this knowledge. How can they study it?

Without thinking too much, this aspect must fall on Wang Yang's head and he will find a solution.

Looking at the bonfire, Wang Yang stared at the ore.

The ore is heated in the fire, and part of it remains its original color, and part of it becomes gray and white. Obviously, the part that turns gray is tin, and what has not changed is other impurities.

I remembered the scene when I was burned when I touched the tin and turned white for the first time, and I smiled slightly.

But suddenly, his smile was stunned, and a light of inspiration flashed in his mind, and the physical changes of tin flashed repeatedly, muttering in a daze.

"The whiter is tin, and the non-whiter is not tin. I need tin, just make it whiter and then take it down..."

"Hurry! Get me a pebble!" Wang Yang suddenly shouted, excited, pulled it to his waist, took down one or two gray animal skins, spread it flat on the ground, and put it in his hands.

Then he took two firewood and grabbed the colored ore from the fire.

At this time, Xiaohong quickly gave him a pebble.

He held the pebbles in his right hand and his left hand covered his animal skin and grabbed the ore.

"Sizi~" The animal skin made a sound that could not stand the high temperature. Wang Yang kept his eyes and gently knocked on the whiter part of the ore with pebbles.

With a light "buzz~", I saw the white tin turning into powder suddenly, falling on the gray animal skin, like snow chips.

It is complete, with only a little impurity.

"Yes, tin that is roasted to more than 100 degrees by high temperature will undergo physical changes, just like water will evaporate at high temperatures, freezing at low temperatures, and tin will become fragile at high temperatures. At this time, a little external force will cause it to fall off completely and turn into powder."

"If I don't let it turn into tin water, but extract it when it turns white, I can extract more tin, which is also purer tin! When I want to use it in the future, heat it to turn into juice!"

As one of the five famous metals, gold, silver, copper, iron and tin, tin is the most susceptible to temperature. It only takes a simple 100 degrees to produce earth-shaking changes. For Wang Yang and others, a temperature of more than 100 is simply easy, and you can have it if you want it.

Even if it is more than 200 degrees, as long as it is burned for a longer time and the firewood is added more vigorously, it can still be achieved.

However, collecting liquid is very difficult, especially high-temperature liquids, which have extremely strong corrosion. When poured on the wood-made formwork, it will cause potholes and erosion, resulting in the inability to form directly and need to be polished.

It will also be mixed with eroded substances, causing a decrease in purity.

If it's just a pile of powder, it's much easier. You just need to lay a piece of animal skin on the ground and you can catch it all.

More importantly, the gravel in the ore will not be mixed into tin, the temperature of the tin powder is not that high, the corrosion is naturally not that strong, the cooling is quite fast, and the purity is naturally increased by more than one level.

"Haha! Fortunately, my mind is turning very fast. I haven't returned the knowledge I have learned to the teachers."

Wang Yang was extremely excited and laughed at everyone.

It is naturally impossible to be so happy that it is just because he can extract more tin, but because he thinks of this, how to mine tin mine!

In school, he always believed that mathematics is not very useful because no matter how fast mental arithmetic is, it is not as fast as computers.

However, later, he found that mathematics is indeed a good subject. The focus is not on its ability to arithmetic, but on its ability to stimulate the flexibility of the brain in disguise.

Those math problems, as long as you work for a long time, you can find a rule, all of which are routines. However, a number is changed to the question, which tests everyone's flexibility to learn from one example and apply it to others. The only thing that remains unchanged can be said to be the two tragic children, Xiao Ming and Xiao Hong.

He was inspired by the moment and naturally thought of how to use it.

Heat all the tin ore to more than 100 degrees? No! Of course not! Absolutely no! That's why you're so stupid! How long does it take to burn and how much wood is wasted? Are you not afraid that the buddies from the Forestry Bureau will invite you to have tea?

What he thought was that when tin was about minus 30 degrees Celsius, it would also turn into powder, and during the ice age, the temperature was about minus 30 degrees Celsius...

"Hehe, hehe." His eyes smiled into a crack. As soon as winter came, there was no need for everyone to do it, and the tin would turn into powder and let everyone take it.

After understanding this, Wang Yang felt his chest relaxed. His future life was so beautiful. Looking at the stars in the sky, he was so intoxicated that he was about to float above the moon.

"I'm such a genius..." He added to himself.

The moonlight fell, mixed with the afterglow of the fire, illuminating his ecstasy look at this moment.

Seeing that he was so funny, everyone couldn't help but laugh. Xiaohong patted his butt in a bad way.

Suddenly, his whole body shuddered, and he shrank his neck in fear, hid aside and looked around, alerting whether there were any "barbaric creatures" approaching.

The exorcist and others asked him what was so happy.

Wang Yang had no choice but to explain this very abstract problem. Generally speaking, it was very difficult to explain to a group of people who did not understand the reason.

Fortunately, he studied liberal arts, so he used water to describe the phenomenon of using water. Only then did everyone understand ignorantly and did not continue to ask.

It’s a blessing that they didn’t ask, otherwise how would Wang Yang explain this chemical phenomenon?

With hope, life will be much simpler.

Everyone is trying hard to hunt, store food, and wait for winter to arrive. After all, this forest is much south and there are still many animals, so it is not difficult to obtain a large amount of prey by relying on various tools.

Wang Yang did not participate. He picked many branches and accumulated dry firewood with his friends to face the severe winter cold.

Not only that, Wang Yang also used the spruce leaves to make many brooms for everyone to clean, including many preparations for collecting tin powder after the day.

As the saying goes, a snake swallows an elephant inadequate heart. If you have something, you naturally want something else.

For example, with tin, I want to find other metals as soon as possible, make hard alloys, and develop more tools.

He ignored the high melting point of other metals and needed the requirements of kilns. As for clay, you can find it more, and metal is the key.

With metal, are you still afraid that you can’t make a kiln?

In that sentence, there will be bread and houses. Let’s buy a good house first and then consider bread.

However, Wang Yang did not regard the above old saying, that is, the sentence that people are not satisfied with their hearts and swallow elephants, as a derogatory meaning.

On the contrary, it is precisely because people's life is getting bigger and bigger that they promote rapid development.

He must always be hungry, even if he has food that he can't finish in his whole life.

Speaking of which, on this day, he came to the forest again, which was far from where they lived and an area that everyone had not yet explored.

But the forest is almost the same, there is no difference.

He came here to find other metals and see if there are more things to use nearby.

As soon as he arrived here, he saw a man, a thin man, holding a not-so-straight wooden spear, looking around alone.
Chapter completed!
