Copper is the beginning of human manufacturing and use of tools.

It is also a sign that human civilization has entered a new chapter!

The advent of copper-based metal tools has brought human civilization to a new level.

The wide application of metallurgical technology and metal products is closely linked to the history of human civilization.

In the live broadcast room, when the audience was cheering, Lu Yu kept looking at the axe blade in his hand, and after a long while, he took a heavy breath and said:

"Our ancestors created a glorious copper culture, and at the same time, they also created a brilliant self. ”

"Maybe what I'm doing doesn't mean anything compared to them. ”

"But through my own efforts, I have completed this cross-generational tribute. ”

"As I said in the live broadcast before, I never advertised anything, and I don't want anyone to run to the desert island to survive for thirty days like me, I just want to tell you: how a person can rely on wisdom to re-establish human civilization without the products of modern civilization at all!"

"If one day, our long-lived homeland changes, as the inheritors of civilization, can we shoulder the responsibility on our shoulders and continue civilization......?

The key to the eternal forging of civilization and life has never been determined by the power of productivity and scientific and technological power.

It's spirit and wisdom.

Brave, decisive, fearless, upward!

In a sense, the literacy of extreme sports is also in line with it.

This novel way of exercising is not just a dead eyeball.

Breakthrough, creation and development are the truths contained in it!

"Well said the anchor!"

"Game guide from the high-end players of Earth OL, fire tongs Liu Ming!"

"Feather God!"

"What a beautiful boy like a god!"

"Sao Nian, you managed to get my attention!"

......

After chatting openly with the audience for a while.

Lu Yu regained his strength, turned around and got busy again.

With an axe blade.

The next thing to consider is to find a properly sized axe handle and set it with the blade.

Then, just polish it a little.

A sharp Viking battle axe can be put into daily use.

"Due to the limited tools, there were no openings when casting the axe blades"

"Once you have found the right handle, you have to make holes in it with charcoal fire, and then tie the blade and handle together with ropes. This method, although not as durable and not as solid as a wedge, is what the Viking Tomahawk originally looked like. ”

"I think that at the beginning, it was with such a seemingly rough axe that the Vikings pried open the armor of the Enamel people in one fell swoop, leaving an immortal legend......

The Vikings, also known as Vikings, were the ancestors of the five countries of present-day Northern Europe.

These berserkers, from the 8th to the 11th centuries AD, roamed the coast of Europe and the islands of Britain, covering a vast territory from the continent to the Arctic.

Historically, this period is known as the "Viking Age".

In Old English, "vikinger" means a person in the bay, and "vikingar" also means "sea adventure" in Icelandic vernacular.

The homeland of the Vikings was Norway, Sweden and Denmark.

In the beginning, they only raided monasteries along the coast of the Western European continent.

It was followed by organized invasions of other European countries, from Ireland to Britain and from Enamel to Eastern Europe......

Vikings armed with tomahawks, can be seen everywhere.

In addition to conquest, the Vikings were also skilled navigators, drifting on the seas almost all year round.

Further west, they gradually discovered Iceland and Greenland, and eventually reached North America.

To the east, at one time they reached the Caspian Sea.

Today, there is a significant proportion of white North Americans, descendants of the Vikings.

......

The choice of axe handle does not need to be too exquisite.

As long as the material is clear, the hardness is passed, and it can be competent.

The eucalyptus trees in the camp are a good choice.

After polishing, the eucalyptus tree will be very comfortable to hold and feel first-class.

But because of the material problem, this kind of wood must take a lot of effort in the process of polishing.

Between words.

Lu Yu squatted in front of the pyre and rummaged for a while.

Finally, I found a piece of wood about 40 centimeters long, with a moderate thickness and a regular shape.

After peeling off the bark, the color and texture of the wood also meet the requirements, and there are no insects and other dark wounds.

And the axe handle was chosen.

Then there's the cliché.

First, the axe handle is sharpened.

Then perforate with charcoal and put in the blade of the axe.

Finally, take another piece of rope and tie a few cross knots at the junction of the axe handle and the blade to secure it.

Soon.

An hour passed imperceptibly.

After Lu Yu's meticulous creation, a copper battle axe with a metallic luster was finally completed and appeared in front of the audience for the first time.

The copper axe blade is not comparable to the stone axe.

The unique metallic luster looks very tasteful.

uneven surface.

It is also very artistic.

After all, it was built with bare hands.

This aura is by no means comparable to the industrialized products of assembly line operations.

"Wait a minute......"

"We're still going to have to find a grinding stone to polish the blade of the axe. ”

Looking at the "new weapon" in his hand, the corners of Lu Yu's mouth kept rising slightly.

It seems that he is very satisfied with this partner.

"The traditional Viking tomahawk axe blade is very different from the average jungle axe. The biggest difference between the two is mainly focused on the cutting method. ”

"Ordinary jungle axes, such as the Swedish Foss axe, are mostly flat-edged. Flat edge, also known as flat grinding, is the most commonly used method for cutting tools, between concave grinding and convex grinding. Sharp and sturdy. The longitudinal section of the blade is V-shaped, also known as V-shaped grinding. ”

"Generally, small outdoor hunting knives are commonly used for large flat grinding, which has strong firmness and strong sharpness, which can meet the functions of chopping bones and peeling. ”

"But the traditional Nordic hunting knife and axe blade, on the contrary, the Vikings have a very deep understanding of the knife, and through the generations, they have created a very special way of cutting - the Scandinavian cutting edge. ”

Scandinavian blade, simply Scandinavian blade.

Cut the edge from the middle of the tool to the sides.

This cutting method can well retain the weight of the blade itself.

It's also very easy to use.

Scanblades are mostly used on traditional Nordic hunting knives, traditional tomahawks, and modern survival knives.

It is a very practical way to cut the edge.

A perfect balance between strength and sharpness of the blade.

This is one of the fundamental reasons why outdoor survival knives are mostly used with Scanner.

None of them.

It's because the blade is thick enough.

And the strength passes.

A scanner blade is enough for survivors to cope with most of the chopping operations in the harsh natural environment.

In this regard, the flat grinding of Damascus cannot be compared.

It's too thin after all.

......

Chatting and talking.

Lu Yu turned to pacing to the fire.

While introducing to the audience.

While from the ashes of the fire, I found a small piece of charcoal.

Along the edge of the blade, a two-sided line was drawn, almost five millimeters wide.

The purpose of the cutting line is to facilitate polishing.

It can be well avoided when sharpening the axe blade, hurting the axe surface and other problems.

"Scanner blade is a double-sided blade, and when drawing the edge line, it is best to take both sides into account. ”

"If you really want to deviate from the blade, it's going to be troublesome. ”

"Combat effectiveness has dropped by at least one notch......"

An anchor who doesn't pay attention to details will definitely not be able to make a good show.

During the live broadcast, Lu Yu has always paid attention to details.

But whenever it is a key point, I will always say two sentences.

Make the program richer and more three-dimensional.

Let the audience participate in it as well.

In fact, this way of commenting really adds a lot of points to this live broadcast.

The most important thing is that the audience also buys it.

At the same time, you can not only learn a lot of unknown survival knowledge.

I also have a deeper understanding of some principles.

Soon.

After drawing the cutting line.

Lu Yu got up and came to the stone statue.

Tie up your horse.

Two-handed blades.

I found a random angle and grinded it according to the area drawn by the blade line.

Elemental copper is still good for polishing.

It didn't take long for the double blades of the axe to take shape.

The whole cutting surface, about five millimeters wide, looks very quaint.

Next, just keep digging into sharpness.

However, cutting is a technical job.

In addition to avoiding edge deviations, it is also necessary to follow the principle of coarse to fine.

In order to ensure the sharpness of the axe blade well.

In short, there are a lot of precautions.

It's also troublesome.

Because the tools in hand are not up to par.

The whole grinding process lasted more than an hour.

During this period, Lu Yu changed several stones of different thicknesses before it was completely completed.

"Whew——! should be fine. ”

Standing up on the blade of the axe, he let out a long sigh of relief.

"Okay, find something to try, how sharp is ......"

The words fell.

Lu Yu looked around.

Eventually, my eyes were set on an acacia tree not far away.

The next second.

Before the audience could react.

But Lu Yu had already pulled out his lunge, raised his hand, aimed at the trunk of the tree, and flew the tomahawk out!

Whoosh——!

The sound of breaking the air was heard in an instant.

The Viking axe spins several times in a row, drawing a graceful arc in mid-air!

In the end, I only heard a "bang".

Look at it again.

The sharp blade of the axe had already stabbed into the body of the tree, and it was more than half pierced.

“666666！”

"Damn! handsome!"

"Olayu, the god of war?"

"Glorious Executioner?"

"God's Axe!"

"It would be awesome if I could pick it up again!"

......

Smiled and glanced at the barrage.

Lu Yu asked, "How is it, brothers?"

"Is it okay?"

After receiving an affirmative reply from the sailors, he continued: "This is the Viking Tomahawk. ”

"You can fly, you can cut, you can fight. ”

"The extra-long scimitar-shaped axe blade is one of the most advantageous means of piercing the enemy's jaw. As long as you succeed, you will either die or be disabled. ”

Between words.

Lu Yu walked over to the acacia tree and pulled up his battle axe.

Later, I found a few more firewoods and tried the chopping strength.

Outcome.

Only three or five times.

The firewood was cut off.

Seeing this, Lu Yu's face was overjoyed.

"It's a copper axe, it's much more powerful than a stone axe. ”

"The efficiency improvement is not a little bit of a star, it is simply a qualitative leap. ”

"If I had it a few days earlier, those eucalyptus trees might not be able to embarrass me, but it doesn't matter, it's all right, because from now on, stone weapons are a thing of the past!"

The advantages of the copper axe are numerous.

But the disadvantages are not without them.

First of all, the most obvious, is that the axe blade is too thin.

It is also thanks to Lu Yu who sharpened the Scanner's blade.

If it is a flat grinding blade, it is almost a sure thing that the lethality will be greatly reduced.

Secondly, the copper is soft because no alloy is added.

Such a problem will directly affect the durability of the copper axe.

In the process of use, it must be ground a lot.

However, with the conditions in front of him, it is already Lu Yu's limit to be able to achieve this effect.

No matter how you say it.

Copper axes are still more powerful than stone axes.

In the live broadcast room.

After the flood of 666 subsided, Lu Yu couldn't wait to carry the bamboo basket on his back.

Along the way, find the small dirt slope where eucalyptus trees used to grow.

Prepare to cut some eucalyptus trees.

By the way, try the power of the copper axe.

Outcome.

Obvious.

It is worthy of a metal blade, even if the material is not up to par, it is much better than a rough stone axe.

Before that, it took at least half an hour to cut down a tree.

But now, in just five minutes, a eucalyptus tree with the thickness of a small arm has been cut off by Lu Yu's roots!

The efficiency is visible!

"Brothers, to tell you the truth, it's really easy to use. ”

"Now you should be able to understand what I said, right?"

"The discovery of copper opened the door to a new world for human civilization and embarked on the road of rapid development in one fell swoop. Just a simple copper axe can solve many of the problems I encounter in survival. But for a nation and a civilization, it can solve much more than that. ”

After speaking.

Lu Yu changed his target again.

Bang bang slashed up.

It was only more than 20 minutes.

There were not many eucalyptus trees left on the dirt slopes, and they were all turned into bundles of firewood.

"Hey...... It's a really amazing feeling......"

"That's what an axe should feel, but to be honest, I'm not used to using a stone axe. ”

After taking off the rope around his waist and tying up the firewood, Lu Yu thrust the copper axe into his waist, turned around and was about to walk back.

Feet can be lifted.

Before I walked down the dirt slope, at the farthest point of sight, an incredible scene suddenly appeared!

The dirt slope is very high.

Standing on it, you can easily see the west coast.

"What's that......"

Unconsciously.

Lu Yu couldn't help but mutter.

His brow furrowed.

The next second.

Following the direction of his finger, the audience also noticed something strange in the depths of the ocean.

I don't know if it's because of the weather or whatever.

A puff of smoke slowly rose out of thin air on the sea level!

It doesn't look like a hurricane or a storm.

Because if that had happened, the weather would have changed a long time ago.

It's never going to be so calm.

It's not a hurricane, what is it?

Boat?

Crash?

Not like.

At this time.

The audience in the live broadcast room also saw this magical scene:

"What's going on?"

"On fire?"

"How is that possible?"

"Thunder and fire!"
