Chapter 819 human limit

valuable?

The audience was stunned. They thought it was just a piece of glass. Even if it was a little rare, it was not very valuable. Maybe it is not the case now?

【I won’t be tired if I say this】

[Slim, how valuable is it]

“Well, I’m actually not quite sure. This piece, about a thousand pieces, looks like a thousand pieces?”

Bi Fang’s tone was not quite sure.

If you look closely at the glass meteorite in your hand at the sun, you can still see that it is in good condition.

The impact of meteorites on the desert is an extremely intense process, which involves a series of complex activities such as high-intensity impact, high-temperature ablation, and surging ambient airflow.

After a violent meteorite impact, it caused a large amount of blowing sand to impact each other. Under the action of high temperature ablation, the prototype of glass meteorite was impacted many times and under the action of strong airflow, meteorite impact, sand and other materials were formed again impact, and Complex textures under the combined effect of airflow.

The impact of this air flow and blowing sand acts on the ablated crystal more than once, thus forming this seemingly simple but multiple intersecting texture from the inside out.

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

The piece in Bi Fang’s hand does not contain too many conspicuous bubbles and impurities, and it is quite clear. Perhaps it can be sold for a high price of tens of thousands in the market.

Of course, it is limited to this. The value is not the same as the giant jade that Bi Fang found last time.

[Inflation is really getting worse and worse, now I hear thousands of dollars, ten thousand dollars, and it doesn’t seem like much (covers face)]

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

[Look around again, maybe there is more, since this thing is pure natural, shouldn’t there be only one piece? 】

Seeing what the audience said, Bi Fang took it for granted, and began to search for similar natural glass nearby.

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

“In 1932, the Central State explorer Patrick Clayton, who discovered the glass meteorite, was determined to go deep into the Sahara Desert for treasure hunting.”

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

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

Perhaps to be precise, since the sixteenth century, the boom in exploration has never ceased, and it has been intensifying until the twenty-first century.

People yearn for more wealth, and in order to get them, the rich and nobles made a lot of investment, which drove batches of navigators to appear.

Columbus and Magellan were the leaders of this period.

This is a relatively primitive and rough adventure, which has filled a lot of human lives, and the value it brings is undoubtedly rich. For the first time, human beings know the whole picture of the world.

By the nineteenth century, human beings at that time already had a specific and detailed understanding of the world, but it was limited to the surface. It was able to clearly point out any position on the globe, but for some dangerous areas, it was still nothing. Knowledge, and the completion of the Industrial Revolution, provided the basic conditions for exploring these dangerous areas.

Amundsen, Scott was a standout at this time.

Polar regions, deserts, rainforests, became the expected places for people in this period.

If the polar regions began to explore the extension of the earth in the 16th century, people tried to know what the northernmost and southernmost scenes of the earth were, then the Sahara and the rainforest were to find something different.

Ancient temples, magnificent pyramids, mysterious totems, natural and beautiful mineral crystals…

“Ha, another piece, still yellow, but not as good as before.”

Bi Fang dug out another piece of meteorite glass full of edges and corners from the sand, simply wiped it and put it away.

“There may be any danger in the depths of the vast desert, and few people try to enter it. What attracts Clayton and others to the hinterland is the lure of treasure hunting.”

“Clayton heard that there is an oasis city in the desert, which hides rich treasures, but the expedition team did not find this oasis city that only existed in the legend, but found something special.”

“I said it once just now, and you all know it now, it’s Libyan meteorite glass.”

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

“But how can you become an explorer without two brushes? This is not a profession that can be achieved by courage and boldness. With his keen geological experience, Clayton feels a little strange, that is, how can it be in a barren desert? Such fine glass appears?”

“But due to the development of the times, he has never been able to find the answer. It’s just that in the next two years, he traveled to the Sahara Desert and Europe many times, collecting many such glass samples.”

“Two years later, Clayton meticulously packaged the collected glass in a whisky bottle. Into the bottle with the glass, there was a small note that recorded the collection of the glass.”

“This bottle of Libyan desert glass stood for 50 years until it was discovered in 1984 by an Italian archaeologist, Giancarlo Canillo.”

“He was equally amazed at 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, Carniro organized an expedition to retrace Clayton’s path. He wasn’t looking for treasure that Clayton didn’t find, but for desert glass.”

“Then in 1996, I just said that the gems on the pharaoh’s head were also glass. From then on, the meteorite glass in Libya became famous and gradually became valuable.”

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

It might add up to about 30,000 yuan?

“It’s been too long since glass was formed. The sand dunes in the Sahara Desert are constantly moving, not to mention the meteorite glass hidden in the desert. I don’t find it strange that they appear anywhere in this desert.”

Bi Fang happily put the three pieces of glass into the backpack, and deliberately separated them to avoid friction and collision with each other, resulting in scratches or bumps.

Thirty thousand yuan, in the past, was already a lot of money for him, and their commemorative significance was far greater than their actual value.

The jadeite was soaked in soup last time, and this time I can finally bring back some valuable minerals, which can be regarded as fulfilling my treasure hunt dream.

After distilling some fresh water, Bi Fang continued on with Alpha.

“After Libya is Chad. This is the trip I am most looking forward to, the heart of death in Africa.”

Chad, a landlocked country in central Africa, has a staggering number of over 200 ethnic groups.

Its territory is mainly divided into three geographical regions: the desert region in the north, the arid Sahelian region in the middle, and the Sudanese steppe region in the south.

Because most of the desert areas are far away from the ocean and are hot and hot all year round, it is also known as the “Heart of Death in Africa”.

Many places here, apart from daily camels and herders, are sparsely populated and are one of the least tourist-visited countries in the world.

The Enedi 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 pearl on the planet that has not been overwhelmed by tourists and crowds and is almost intact.

After taking a sip of water, Bi Fang re-judged the direction.

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

That is Lake Ummmai in Libya.

Ummmai means “Mother of Water” and is one of the largest oasis lakes embedded deep in the sand dunes of the deep Sahara.

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

“The Sahara has only two permanent rivers and a few lakes, but it has massive underground reservoirs or aquifers.”

“Its permanent rivers are the Nile and the Niger. The Nile originates in central sub-Saharan Africa, flows northward through Sudan and Egypt, and ends up in the Mediterranean.”

“The Niger River originates in West Africa, in the southwest of the Sahara Desert, flows northeast into Mali, then turns southeast, through Nigeria, and into the Gulf of Guinea.”

“It doesn’t have many permanent lakes, there are only about 20 lakes, and only one of them has drinking water, and that is the vast and shallow Lake Chad. As you can tell from the name, right in the territory of our next destination, it is a Lakes that keep expanding and shrinking. Others are filled with undrinkable salt water.”

“Ummmai is one of the best, and it’s on my way, and it’s a must-see anyway.”

[No, what is the oasis in the oasis that the **** of the party met before? That doesn’t seem to be a saltwater lake, right?]

[That’s not a lake, is it? 】

【It can only be counted as a water pool】

“The definition of a lake is a water area surrounded by land on all sides. Although no one has ever defined how big a lake is, the small oases we have experienced obviously cannot be counted.”

Bi Fang explained with a smile.

It is now the end of July, and the temperature of the sand in the Sahara Desert can exceed 70 degrees, and the surface of the sand has no traces of water at all.

Just thinking about being able to see a big lake is bound to make people excited.

That night, Bi Fang rarely chose to travel overnight.

Under the starry night, billions of tons of sand slid, accompanied by a humming sound that echoed several kilometers away.

Singing sand dunes, one of the characteristics of the Sahara, have experienced constant sand avalanches over the years.

With the somewhat terrifying “background music”, the next morning, Bi Fang saw his destination in sight.

Big is indeed big, and it pales in comparison to what Bi Fang has encountered before.

Different from what I imagined, although there is also green grass around Ummai Lake, there are not many animals here, and it is not a lively scene at all, and there are only endless flies.

【Depend on. . . What’s so cool about this thing. . . 】

[I vomited, a little nauseated]

【There are too many flies】

[This thing is the mother of water? I’m a little suspicious of life

“Hahaha, I never said where Ummai is alive, maybe a long time ago, but not anymore.”

Bi Fang rode a camel and looked at this huge lake. He couldn’t say whether he was emotional or what.

“Ummmai is a very special lake of death. After tens of thousands of years of high temperature evaporation, the lake water contains a lot of salt, plus the rotting carcasses of various animals, the lake water contains a lot of toxins, and it is impossible to drink. ”

“Most of the animals that died near this lake were poisoned by thirst or accidentally drinking the lake water, and their deaths further enhanced the toxicity of the lake water.”

“There are also 16 lakes around it, some of which dry up and disappear from time to time, while others persist in the embrace of the desert. This saltwater lake used to be a well-known trading center for the local population.”

“However, as the lake gradually became dirty, it gradually became abandoned.”

“One of the more interesting things is that the lake here has a very high salt concentration, which is even comparable to that of the Dead Sea, so it is very easy to swim in it.”

[I vomited, who would swim in this?]

【Go down and eat flies? 】

【When did Fang Shen become so disgusting】

The audience could not accept Bi Fang’s heavy taste.

“Just kidding, I don’t want to eat flies either.”

Bi Fang shrugged and then pointed to the lake.

“It’s a pity it’s not October, otherwise we could see a lot of swallows here.”

【swallow? 】

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

“Yes.”

“All the migratory birds in the world migrate at specific times every year, and their migration routes remain unchanged for thousands of years.”

“Just like some fish migrate every year to their birthplace to spawn, even if the journey is long and dangerous, they will continue to migrate.”

“Swallows are one 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 winter.”

“The most difficult thing to solve when crossing the ten thousand miles desert is the supply problem along the way. Although they have strong stamina and light body, the consumption of the 10,000-mile rush road is also huge, and they also need sufficient food and water to supplement their physical strength so that they can go smoothly. Complete the migration.”

“Although there are not many water sources in the desert, as I said, birds will not easily change their migration routes. There is only one source of water on their migration routes, and that is Lake Ummmai.”

“It is obviously impossible to drink it directly. It will be poisoned in minutes, and it will be the same as the corpse of a nearby animal.”

[Damn, I already know]

[Stop talking, save some face for Yanzi]

[Enough has been tasted. 】

“But we can’t ignore one important creature, the ubiquitous fly.”

The humming of flies constantly flying on the water seemed to respond.

“As the decomposers of nature, flies can filter the toxins contained in the lake water. UU reading www.uukanshu.com So flies can replenish water and physical energy for swallows, and even small flies are meat.”

“Hundreds of flies go down, and the swallows are full of energy, and they flutter their wings and continue southward to the destination of their migration.”

The audience in the live broadcast room was nauseated for a while, and Bi Fang laughed.

“If you really can’t hold on in the desert, and you can’t drink salt water, can you also challenge the limits of human beings?”
