Valuable?

The audience was in high spirits, originally thinking that this was just a piece of glass, even if it was a little rare to form, it was not very valuable, but now it seems that this may not be the case?

[If you want to say this, I'm not sleepy]

[Talk, how valuable is it]

"Well, I don't really know, this piece, about a thousand pieces, ten thousand pieces?"

Bi Fang's tone was uncertain.

If you look closely at the glass meteorite in your hand at the sunlight, you can still see that the color is good.

The impact of meteorites on the desert is an extremely intense process, which includes a series of complex activities such as high-intensity impact, high-temperature ablation, and environmental air surge.

After a strong meteorite impact, a large amount of sand is caused to impact each other, and under the ablation of high temperature, the prototype of the glass meteorite has been impacted many times and formed under the action of strong air flow, the meteorite impact, the sand and stone and other materials impact again, and the complex texture under the combined action of the air flow.

More than once, the impact of this air flow and blowing sand acts on the ablated crystals, creating this seemingly simple but multi-faceted texture from the inside out.

It is very difficult to forge it, which further increases the value of glass meteorites.

Bi Fang's hand, there are not too many conspicuous bubbles and impurities inside, it is quite clear, maybe it can be sold at a high price of tens of thousands in the market.

Of course, that's all there is to it, the value is not the same as the giant jade Bi Fang found last time.

[Inflation is really getting worse and worse, and now I hear thousands of dollars, ten thousand dollars, it doesn't feel like it's anything (covering my face)]

[I bought breakfast this morning, and I found that the potato cake downstairs had risen by two pieces, which made my heart ache, woo woo]

[Look for it again, maybe there is more, since this thing is pure natural, there shouldn't be only one piece, right? ] 】

】

Bi Fang saw what the audience said and was deeply impressed, and began to search the neighborhood to see if there was similar natural glass nearby.

Although the value of the glass itself is not high for Bi Fang today, there is a unique pleasure in finding them, like finding a treasure in the wilderness.

"In 1932, Patrick Clayton, the explorer of the central country who discovered the glass meteorite, decided to go deep into the Sahara Desert in search of treasure."

Bi Fang stuffed the yellow meteorite glass into his backpack and began to search for gems near the oasis, while also doing some simple historical science.

In the middle of the 19th century, with the completion of the Industrial Revolution, the world's major capitalist countries at that time moved towards the stage of monopoly capitalism and the direction of foreign aggression and expansion, followed by a vast expedition.

Perhaps it is accurate to say that the craze for exploration has not ceased since the sixteenth century, and it has been intensifying until the twenty-first century.

People craved more wealth, and in order to obtain them, the rich and nobles made large investments, which drove the emergence of one navigator after another.

Columbus and Magellan were both prominent figures of this period.

This is a relatively primitive and rugged expedition, for which a lot of human lives are filled, and the value brought is undoubtedly rich, and for the first time mankind knows the whole picture of the world.

By the nineteenth century, human beings at that time had a specific and detailed understanding of the world, but it was only superficial, and could clearly point out any direction on the globe, but there was still no knowledge of some dangerous areas, and the completion of the industrial revolution provided the basic conditions to explore these dangerous areas.

Amundsen and Scott were prominent figures of this time.

The polar regions, deserts, and rainforests became the desired places of this period.

If the polar regions began in the 16th century, exploring the extension of the earth, and people trying to know what the northernmost part of the earth was like, then the Sahara and the rainforest were just to be able to find something different.

Ancient temples, magnificent pyramids, mysterious totems, naturally beautiful mineral crystals......

"Ha, another piece, it's still yellow, but the texture is not as good as just now."

Bi Fang dug out another piece of angular meteorite glass from the sand, wiped it briefly and put it away.

"There are any dangers that can arise in the depths of the vast desert, and few people try to get into. And what attracts Cleighton and others to go straight to the hinterland is the temptation of treasure hunting. ”

"Cleton heard that there was an oasis city in the middle of the desert that was rich in treasure, but the expedition team did not find this legendary oasis city, but found something special."

"I've already said it once, and you all know it now, it's Libyan meteorite glass."

"At first, Cleton just thought the glass was new and beautiful, so he collected it and brought it back to Europe."

"But how can you be an explorer without two brushes? This is not a profession that can be done by courage and boldness, and with his keen experience in geology, Creighton felt a little strange as to how such fine glass could appear in the barren desert. ”

However, due to the development of the times, he has never been able to find an answer. It was only over the next two years that he traveled back and forth between the Sahara Desert and Europe several times, collecting many of these glass samples. ”

Two years later, Cletton carefully encapsulated the collected glass in a whiskey bottle. Along with the glass, there was a small note on which the glass was collected. ”

"The bottle, which was filled with Libyan desert glass, sat out for 50 years until 1984, when an Italian archaeologist, Giancarlo Caniro, discovered the bottle."

He was equally amazed by the beauty of the glass and the mystery of its unknown origin, and the detailed collection of notes gave him a bold idea.

A year later, Caniro organized an expedition to retrace the path of Clayton. He wasn't looking for a treasure that Cletton hadn't found, but he was looking specifically for desert glass. “

"Then it was 1996, and I just said that I found that the gem on the pharaoh's head was also glass, and it was probably from that time that the Libyan meteorite glass began to become famous and gradually became valuable."

After looking around for a long time nearby, Bi Fang only found three pieces in total, of which the first one was the best, and the last two were not very good.

Maybe it adds up to about 30,000 yuan?

"It's been so long since the glass was formed, and the dunes of the Sahara Desert are constantly moving, not to mention the meteorite glass hidden in the desert, and I don't think it's strange that they appear anywhere in the desert."

Bi Fangmei put the three pieces of glass into the backpack, and deliberately separated them to avoid rubbing and colliding with each other, causing scratches or bumps.

30,000 yuan, in the past, is already a lot of money for him, and their commemorative significance is far greater than their actual value.

The last time the jade soaked in the soup, this time I was finally able to bring back some valuable minerals, which can be regarded as the fulfillment of my dream of treasure hunting.

After distilling some water, Bi Fang continued with Alpha.

"Libya is followed by Chad, and this is the trip I look forward to the most, the heart of death in Africa."

Chad, a landlocked country in central Africa, is home to a staggering number of more than 200 ethnic groups.

Its territory is divided into three main geographical regions: the desert region in the north, the arid Sahel region in the center, and the Sudanese steppe region in the south.

Because most of it is a desert area, far from the ocean, and it is hot all year round, it is also known as the "heart of death in Africa".

Many places here, with the exception of everyday camels and herders, are sparsely populated and are among the least visited countries in the world by tourists.

The Ennedi Plateau, located right in the middle of the Sahara Desert in northeastern Chad, is not only one of the most remote and beautiful deserts in the world, but also a hidden jewel on earth that has not yet been overwhelmed by tourists and crowds and is almost intact.

After taking a sip of water, Bi Fang rejudged the direction.

Before going to Chad, he had another place in Libya that he wanted to "check in".

That is Lake Ummai in Libya.

Ummai, which means "mother of water", is one of the largest oasis lakes and is deeply embedded in the sand dunes of the deep Sahara.

But for those brave and adventurous travelers, these are not reasons to stop them, and can even be seen as a precondition for receiving a reward, and the ultimate reward is that the reward is the oldest oasis in the Sahara Desert, a surreal landscape.

"The Sahara has only two permanent rivers and a handful of lakes, but it has a large number of underground reservoirs or aquifers."

"Its permanent rivers are the Nile and the Niger. The Nile River originates in sub-Saharan Africa and flows north through Sudan and Egypt before flowing into the Mediterranean. ”

"The Niger River originates in West Africa, in the southwestern part of the Sahara Desert, flows northeast into Mali, then turns southeast, passes through Nigeria, and flows into the Gulf of Guinea."

"It also has not many permanent lakes, about 20 or so, and only one of them has drinking water, and that is the vast and shallow Lake Chad, which, as the name suggests, is an ever-expanding and shrinking lake on the territory of our next destination. Other lakes are filled with undrinkable salt water. ”

"Ummai is one of the best, and it's on my route, so I'm going to see it anyway."

[No, it's only more than twenty of them, what are the oases that Fang God encountered before? It doesn't seem like a saltwater lake, right?]

[That's not a lake, is it?] 】

[Can only be counted as a waterhole]

"The definition of a lake is a body of water surrounded by land on all sides, and although no one has ever defined how big a lake is, the little oases we have experienced are obviously not counted."

Bi Fang explained with a smile.

It's the end of July, and the sand in the Sahara Desert can reach temperatures of more than 70 degrees, and there is no trace of water on the surface of the sand.

Just thinking about seeing a large lake is exciting.

That night, Bi Fang rarely chose to rush overnight.

Under the starry night, 1 billion tonnes of sand grains slide, accompanied by a humming sound that echoes for kilometers away.

Singing sand dunes, one of the characteristics of the Sahara, have been sand and collapsed over the years.

Accompanied by some terrifying "background music", the next morning, Bi Fang saw his destination in sight.

Big is indeed big, and it is completely small from what Bi Fang encountered before.

Contrary to what you might expect, although there are also green meadows around Ummai Lake, there are not many animals here, and it is not a vibrant scene at all, and there are only endless flies.

[Damn.]

。 What's so nice about this thing.

。 】

[I threw up, a little nauseous]

[There are too many flies, isn't it?]

[This thing is the mother of water? I'm a little skeptical about life]

"Hahaha, I've never said where Ummai is alive anymore, maybe a long time ago, but not anymore."

Bi Fang rode a camel and looked at this huge lake, and he couldn't say whether he was feeling or what was going on in his heart.

"Ummai is a very special lake of death, the water here has evaporated after tens of thousands of years of high temperatures, contains a lot of salt, plus the rotting carcasses of various animals, the lake water contains a lot of toxins, and it is simply undrinkable."

"Most of the animals that died near the lake died of thirst or were poisoned by drinking the water by mistake, and their deaths further strengthened the toxicity of the lake."

"There are also 16 lakes around it, some of which dry up and disappear from time to time, while others remain in the bosom of the desert. This saltwater lake was formerly a famous trading center for the local population. ”

"But as the lake got dirty, it fell abandoned."

"One of the interesting things is that the salt concentration of the lake is very high, even comparable to that of the Dead Sea, so it's very easy to swim in it."

[I vomited, who will swim in this]

[Do you go down and eat flies?] 】

[When did Fang Shen become so disgusting]

The audience can't accept Bi Fang's heavy taste.

"Just kidding, I don't want to eat flies either."

Bi Fang shrugged, then pointed to the lake.

"It's a pity it's not October, otherwise we could see a lot of swallows here."

【Swallows? 】

[I remembered, Fang Shen seemed to have birds in that oasis just now]

"Yes."

"All the migratory birds in the world migrate at a specific time every year, and their migration routes have remained the same for thousands of years."

"Just like some fish migrate to their birthplace every year, they will continue to migrate even when the road is long and dangerous."

"Swallows are part of these migratory armies, and European swallows fly thousands of miles south every winter, across the Sahara Desert into Africa, where they spend the cold winters."

"The most difficult thing to solve through the desert is the supply problem along the way, although they have strong endurance and light bodies, but the cost of the 10,000-mile-long journey is also huge, and they also need enough food and water to replenish their physical strength in order to successfully complete the migration."

"Although there is not a lot of water in the desert, like I said, birds don't change their migration routes easily, and there is only one source of water on their migration route, and that is Ummai Lake."

"It is obviously impossible to drink it directly, you will be poisoned in minutes, and it will be the same fate as the carcass of nearby animals."

[Damn, I already know]

[Don't say it again, save some face for the swallow]

[I've tasted enough.] 】

"But we can't ignore one important creature, and that's the ubiquitous fly."

The buzzing of flies on the surface of the water seemed to respond.

"As decomposers of nature, flies filter the toxins contained in the lake water. Therefore, flies can replenish water and physical strength for swallows, and no matter how small the legs of flies are, they are also meat. ”

"Hundreds of flies are in their stomachs, and the swallows are full of energy, and they flutter their wings and continue to move south, to their migratory destination."

The audience in the live broadcast room was sick to their stomachs, and Bi Fang laughed.

"If you really can't hold on to it in the desert and can't drink salt water, can you also challenge the limits of human beings?"
