I am the king of the wild live

Chapter 9 and Six

Wang Yu patted the salt and sand on his hands and said to the camera: "There is no water on it. This is a dry salt lake, which can also be called a solid salt lake. Due to the year-round sunshine and wind and sand erosion, a kind of salt has formed on it. The hard shell of the mixture of species and sediment, the salt cap, is very hard in texture."

While speaking, Wang Yu stomped vigorously with his right foot, leaving no footprints on the hard salt cover, let alone cracked.

"The hardness of this kind of hard salt crust is no worse than that of concrete. Don't underestimate its bearing capacity. After mechanical tests, they can withstand a pressure of more than 14 kilograms per square centimeter. Building factories, airports, Or maybe the railway won’t be a problem!”

The Chaerhan Salt Lake Railway section of the world-famous Qinghai-Tibet Railway is built on the salt rock layer. It is very difficult to construct on the plateau, especially on special geological sections, especially considering the consequences of salt corrosion.

But this kind of problem is still not there. Is it true that in China, the so-called infrastructure madman, the 32-kilometer Salt Lake Railway is built in the "vast snow" heavenly world, and the towering mirages attract a large number of tourists every year.

What Wang Yu is now is also a beautiful dry salt lake. The white salt and sand boards form a seemingly solid land.

When you look at it from a distance, the salt lake is still pure white. When you look at it closely, you can find that it is covered with a lot of sediment and impurities, but the white salt stains and salt frost look bright under the sunlight and look whiter. some.

"Now, I need to take some salt blocks. This is an important resource in desert areas. For me, it is as difficult to find as water resources, so I will not give up any edible salt. Chance!"

After finishing speaking, Wang Yu bent down and tried to break the salt block with his fingers. To everyone's surprise, the salt block looked solid but was not brittle. When Wang Yu pressed his fingers hard, there were signs of loosening. Although Just a thin layer of salt, but a good sign for Wang Yu.

"Although the texture of salt rock is relatively hard, due to being exposed to direct sunlight all the year round, the water in these salt blocks full of sediment impurities has long been evaporated, so the texture is relatively brittle. Concentrating on one point of stress can produce a lot of damage by smashing it. The effect is pretty good. In a simple word, hard work can produce miracles!"

Wang Yu explained, taking out the scimitar dagger from his waist while speaking, holding the handle of the knife, and smashing down hard with his arm.

"Boom!" There was a muffled sound, and the salt shell cracked, forming a circular pit with a handle in the center, surrounded by dense cracks. Wang Yu tapped the remaining three corners several times, and finally used a dagger to touch the edge. The corner connection parts are pried open in turn.

After a while, a large square stone covered with white salt frost and yellow impurities was obtained. Feeling the precipitation in his hand, Wang Yu showed a satisfied smile on his face. Such a large piece of salt rock is far enough for him The next month's "expenses" are gone, at least I don't have to worry about it anymore.

Wang Yu raised the palm-sized rock salt, pointed at it and said, "Look, there are a lot of impurities on it, here, and here, the yellow-brown ones on it are all silt impurities, I don't know what happened to them After many years of accumulation, they have become one with the salt block."

"Although there are a lot of impurities on it, most of the impurities can be removed after manual polishing. It is full of white and green salt grains. It is undoubtedly good news for me. It can replenish what I have in my body. I don’t need to worry about any more salt!”

Wang Yu had a smile on his face. In the desert, dehydration is the biggest enemy. In addition, inorganic salts lost with body fluids are also a big problem.

"If I'm not mistaken, this kind of salt is called green salt, or lake salt, rock salt, generally!"

Wang Yu put the salt block on the camera and said, the so-called green salt or lake salt or rock salt is actually a kind of salt that is directly dried in the salt lake from the brine of the inland salt lake. There is a certain difference, but the difference is not big.

The main component of green salt is sodium chloride, but many people don’t know that it also contains many mineral elements that can maintain the body’s electrolyte balance.

Inorganic salt in the human body is an important substance for life activities. If it is lacking for a long time, it will lead to various diseases, not to mention, even daily activities will be restricted, and the limbs will become weak. The importance is self-evident.

After inserting the dagger into the scabbard, Wang Yu put the heavy salt rock in his hand into the compartment of his backpack and spoke slowly to the camera.

"Don't underestimate table salt. As an important resource, the franchise of table salt began as far back as the Spring and Autumn and Warring States Periods. Table salt has always been a valuable item in feudal society, and was used by successive rulers as a tool to plunder people's wealth."

“The profits from the production and sale of salt for the government were astonishingly high. After the An-Shi Rebellion, they were even as high as half of the fiscal revenue. However, the price of official salt was of high quality and low quality, while private salt was cheap and good. Many people even risked the death penalty in order to make huge profits from selling salt. "

A few years ago, the government abolished the salt monopoly system and opened up the price of salt in the true sense. Before that, it was illegal to sell salt across regions. There was also a restaurant in Shaanxi that was banned by the local salt bureau for buying salt in Xi’an. punishment thing.

Even in modern society, the government's control over table salt has only been completely released for a few years. Naturally, it is not difficult to see that the most common table salt is so important to people.

Wang Yu strode forward with his backpack on his back, and said to the camera: "This salt lake has dried up long ago, and it is very likely that it has existed for thousands of years, or even tens of thousands of years or even longer. As for the cause of formation, I have a bold idea but can't confirm it!"

Wang Yu held his chin and thought: "This area was probably an ocean a long time ago. After crustal movement, submarine volcanoes erupted. After the magma gushes out, it is cooled by the seawater until it forms stiff basalt, forming a dykes.

A large area of ​​seawater is enclosed in the inland area. Under the influence of the sun and wind, over the years, the seawater in this area gradually evaporates, forming a salt area. "

"Of course, these are all my personal speculations, for reference only!"

After speaking, Wang Yu added.

Considering the current situation on the ground, the possibility of this formation is very high. However, as soon as these words came out, many viewers expressed their opinions. There were many people who felt that it made sense, and there were also many people who expressed doubts.
