The Ultimate Live Superstar

The ore is not large.

Just enough to hold in one hand.

Year-round feng shui sun,

So that the surface is covered with soil stains.

However, in the sun, you can still see the luster hidden inside.

light.

Yingying shines.

The metallic luster unique to this ore.

It is by no means what ordinary cobblestones have.

so.

Very easy to tell.

Common copper ore.

Generally, it is an aggregate composed of copper sulfides or oxides and other minerals.

It reacts with sulfuric acid to produce blue-green copper sulfate.

Based on this generative feature.

Chalcopyrite is distributed all over the world.

The specific causes of copper mines.

Very complicated.

But at the end of the day.

Most are acidic rocks.

for various reasons.

Oxidation occurs.

Oridia Island, where Lu Yu is located, meets this condition.

due to changes in the seafloor crust.

It has caused great changes in marine volcanic rocks.

Formed the island's mountainous landforms.

later.

After a long period of geological changes.

The horn porphyry and spilite in the crust are organically combined.

After a long period of oxidation, ore is finally formed.

As such.

It is not surprising that copper mines can be found here.

Not surprisingly.

There should be a lot around here.

For ore of similar origin, the copper grade is generally greater than 1%.

The quality is not the best, but it is easy to smelt.

primitive man of the late Stone Age.

It is the use of this most primitive and rough rock containing copper sulfate to smelt various bronzes.

As a result, productivity has been greatly improved, and human civilization has moved to a new level.

in the live room.

A group of water friends.

After listening to Lu Yu's words, after realizing it, they discussed sentence by sentence in the barrage:

"Copper mine?"

"It would be perfect if it were a gold mine!"

"Upstairs, what do you think?"

"Looking at Yushen's expression, I'm really afraid that he won't be able to control it, so he takes a bite, and then says: six times as much as beef!"

"Haha, who are you trying to laugh at?"

"Visually predict the high energy ahead!"

"It feels like Yushen is about to live again!"

...

near the rock.

There are many similar ores.

Different sizes.

Form and regular.

The copper content is also considerable.

So ever.

Lu Yu kept doing it.

It was not until all the ores suitable for smelting were collected that he explained to the audience in the live broadcast room:

"Why did the Oridians build breathtaking giant stone statues in an era of limited productivity?"

"The reason is nothing more than that they have mastered the smelting technology and can create handy tools."

"Although pure copper cutting tools are soft in texture, if they are applied to production and life, they can create a splendid civilization."

"For the Oridians, metal knives can increase their productivity."

"But for me, the same is true of the metal cutting tools in hand. In an isolated island, in order to cope with the potential crisis, we must maximize our resources."

"Whether it's improving your quality of life or your own combat effectiveness, this is the foundation of your life when you're alone!"

"So, it's time to show the real technology."

"Perhaps we can also try to use these ores to smelt pure copper in the most primitive way, and make some weapons and cutting tools. If that is the case, the efficiency of hunting will definitely be improved to a higher level."

Smeared the wooden arrow that sees the blood seal the throat.

The lethality is not to be underestimated.

But compared to the arrowhead made of copper, the penetrating power is almost meaningless.

When hunting wild boars by the river before, it was because of the penetrating power of wooden arrows.

That's why Lu Yu chose to go shirtless.

At that time, if you had a copper arrow in your hand, it might not be so troublesome.

Powerful hunting, paired with a metal arrowhead, even an adult wild boar with rough skin and thick flesh is no longer a problem.

...

in this world.

Most people's established impression of metal smelting still remains in the mechanized heavy industry.

Thought to be unarmed.

It is simply not competent for such high-end metal work.

Therefore, after listening to Lu Yu's words, the barrage in the live broadcast room suddenly increased.

Some are amazed.

Some are also questioning.

And can not understand the mystery of the original smelting technology.

"Fuck!?"

"Anchor, are you kidding me?"

"Bronze made by hand? Would you like to do this?"

"Break! Bull!"

"Congratulations to the player, the plot: The Stone Age mission has been completed! The next level is about to start!"

"The anchor is going from the Stone Age to the Bronze Age!"

"Earth people can no longer stop Yushen's footsteps!"

"I can't imagine, it feels like the anchor is bragging, but I can't find any evidence..."

...

Facing the audience's doubts, Lu Yu smiled lightly.

did not take it to heart.

Maybe for them, this kind of work does sound a bit outrageous.

With just your hands, you can forge metal.

How can those professional smelters suffer from such a riotous operation?

Of course, it's not the audience's fault either.

In this era when primitive technology has long since died out and received no attention, it is normal for everyone to have this reaction.

But as long as you think about it carefully, the reason will not be puzzling.

Back then, didn't the primitive man start all this while he was unarmed?

We, who are also highly intelligent, why can't we do it?

In fact, as early as the late Neolithic Age, humans began to try to use metal utensils.

Copper first.

Then there is the alloyed bronze.

After that, because there is a suitable forging tool.

Ironware also took root and spread all over the world.

So far.

Human society has entered a stage of rapid development.

until today.

but.

Speaking of which, metal smelting is really a big project.

Without professional knowledge and corresponding equipment, it is extremely difficult to achieve.

then.

Put the collected ore into the bamboo basket.

Lu Yu found a tree shade and sat down at random, and finally opened his mouth slowly:

"Everyone is right, smelting metal is not an easy task."

"But that doesn't mean anything."

"The ancestors of human beings obtained bronze as early as the fourth or fifth millennium BC."

"So, smelting metal may sound outrageous, but in fact, this operation is not as complicated as we think."

At this moment.

After listening to Lu Yu's words, many viewers discussed in the barrage, how did primitive people learn to smelt copper?

This question seems simple, but it is not.

There are a lot of knowledge points involved.

in other words.

In nature, primitive people seem to have no chance at all to experience the chemical phenomenon of ore melting at high temperature!

Lightning fell and fire was found.

Grilling food with fire will make the food more delicious

If the soil is thrown into the fire, it will be fired into pottery.

Finally, here comes the problem.

How did they discover and master the difficult technology of metal smelting?

The audience was puzzled by this.

Various sayings abound.

Very tech-savvy.

Some say it was taught by aliens.

Others say it is an invasion of a higher civilization.

What's more, he even took out Fengshen Romance.

It has a nose and eyes, and it makes a lot of sense.

Really speechless.

Leaning on the stone wall.

Lu Yu couldn't bear to interrupt when he saw the heated discussion in the barrage.

After a while, I explained the ins and outs of this place to the audience one by one.

"Brothers, interrupt you, why are you talking more and more outrageous."

"This problem is actually very simple, and it is not as complicated as you think."

"In smelting, there must be fire first. This is a must. As for how fire was discovered, I have already explained it to you in the previous live broadcast. After there is fire, people will find that they use fire to burn some things, and there will be unexpected things. surprise."

"Like food and clay."

"It's all a product of this point in time."

"I learned to use fire and mastered the use of fire to burn clay containers. During this process, the ore contained in the clay was thrown into the fire unintentionally, and it was burned and melted. People began to realize that the ore can be restored to a harder metal. , and more powerful than a stone tool in hand!"

"So, people started to build earthen kilns and learned to use charcoal and simple blowers. After going back and forth, copper was naturally smelted."

"Later, because of the emergence of a centralized regime that controls a larger area and population, with a certain amount of manpower, people's metal smelting has also entered the right track, and large-scale production in the true sense has begun."

after mass production.

Elemental copper with a soft texture can no longer produce the needs of life.

so.

People added a small amount of tin to it, which turned into a copper alloy.

got here.

Primitive man completely bid farewell to stone tool production tools and entered the Bronze Age in one fell swoop!

Under Lu Yu's explanation.

An easy-to-understand history of human development suddenly came to life.

The 666 of the water in the barrage:

"6666, the anchor knows so much!"

"A conversation with you is better than ten years of reading!"

"Douyu TV Wilderness University Distinguished Professor!"

"learnt!"

"I like listening to Yushen tell stories the most!"

"A cross talk actor who was delayed by the extreme live broadcast..."

"Ha ha!"

...

A quarter to one in the afternoon.

The sky gradually became cloudy.

hot sun.

obscured by thick clouds.

It made the temperature in the forest a lot more comfortable.

In the sky above, a few seabirds flew by from time to time.

Leaving a desolate and mysterious cry.

Take a break.

We were almost talking.

In order to return to the camp as soon as possible, Lu Yu put on his rucksack and continued westward along the river.

As he was on his way, he said as he walked:

"If I didn't guess, Olidia's mineral resources should also be very rich, not only brass, but also rare tin copper and red copper."

"Because only brass is used, it is difficult to perform such a complex carving process."

"In fact, half of the traces of metal we found in the quarry were from bronze."

"So, the smart Oridians must have had a relatively advanced smelting technology a long time ago."

"Speaking of which, it may be earlier than any ancient civilization in the world, which is unbelievable..."

talking room.

The light in the woods began to dim.

The terrain is steep.

Completely one-sided situation.

Must be very careful.

Otherwise, it is very easy to miss.

when you come.

Lu Yu walked to the right bank.

Now he is on the left bank.

Look no further than a river.

But the scenery on both sides is very different.

Different from the right bank, the landforms here are much steeper.

All very rough rock belts.

Very bad to go.

It was difficult to walk all the way, and it took a full hour before the soil returned to my feet.

Holding a tree and gasping for breath.

Lu Yu wiped his sweat and was about to speak.

The eyes were attracted by the black thing hidden in the bushes!

Seeing this, he took three steps and made two steps, and rushed over immediately.

result.

Not surprisingly.

Take a look at the grass.

Indeed found.

It turned out that what was hidden under the grass was a huge, dark, sloping cave!

The entrance of the hole is several feet square.

Enough to fit the next car.

Lots of ivy and moss attached to the edges.

It looks a little vicissitudes.

The light in the cave is poor.

Can't see five fingers.

Not even knowing where to go.

The most surprising thing is that there is a long otolith statue standing at the entrance of the cave.

The long-eared stone statue is an auspicious object built by Oridia to protect the sun goddess.

so.

This inconspicuous cave should also have some unknown origins with the Oridian civilization...

"Brothers, there is a hole here."

"Beside the entrance of the cave, there is also a stone statue..."

While speaking, Lu Yu stood in front of the cave and stuck his head out to look inside.

But because the light is too poor, it is impossible to see the specific situation at all.

Just feel the gloomy wind.

It's cold.

Incompatible with the sweltering heat in the jungle.

Secondly, the humidity in the cave is also very large.

There seems to be a sound of water inside.

Other than that, nothing was found.

Standing in front of the cave, he weighed it, and finally, Lu Yu spoke again:

"This surface cave is very unusual..."

"Maybe there's something hidden in there..."

Looking into the dark cave.

Lu Yu put on a thoughtful expression.

Finally decided to go and see:

"How about it, brothers, are you interested in going down with me?"

"11111111"

"The hole must be drilled on the line?"

"Upstairs, I seriously doubt you're driving!"

"23333333"

"Is it alright to drill on the wall?"

"Go to the northeast to dig coal, stand by, go now!"

...

After getting a positive answer from the audience, Lu Yu left the entrance of the cave.

Searched in the woods.

Cave exploration, you can do without any equipment, but the only thing you can't do without torches.

Not even with the perfect lighting tool in hand.

The only way to monitor air quality without a gas mask is to rely on torches.

Only in this way can the oxygen content in the cave be accurately determined.

No accident will happen.

"Before I go in, I have to figure out how to make a sustainable torch..."

"Right now, we don't know anything about this cave, so torches are essential..."

talking room.

Lu Yu glanced around.

Found several chestnut-shaped taupe tree nuts at his feet.

These nuts all fell from a tall evergreen tree beside him.

Seeing this, he hurriedly squatted down, picked up a few and put them in the palm of his hand, and asked the camera:

"In the live broadcast room, does anyone know this thing?"
