The space inside the cave is probably a spherical hollow, and the seawater is infiltrated into this spherical space through the large hole in the rock wall. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

And above this star space, there is a straight up and down passage, so that a certain amount of air can be preserved in this spherical cave, and this air happens to be the same as the sea water in this cave, because of the topography, maintaining a subtle, but balanced air pressure, resulting in the sea water can only be submerged to half of this spherical hole, just above the hole, leaving such a semi-circular space.

At high tide in the evening, the sea water will flood the spherical hole, squeezing out all the air, and when the tide goes down in the morning, the sea water will automatically withdraw from the hole due to the air pressure, leaving half of the hemispherical space.

And the conversion of sea water and air back and forth provides a very rich amount of plankton in the sea water in this hole, and these plankton provide a very good living space for those polyps, so this spherical hole will be full of such beautiful red coral.

Because it is in this cave, the space is closed, and the air and sea water are converted back and forth, so the pressure of the sea water in this hole will be very high every time the tide rises, which forms a very perfect condition for these polyps to form coral trees after death.

In addition, it may not have been visited by people for thousands of years, so this hole full of red coral trees is left.

At this time, Jin Muchen floated on the surface of the water and looked around, his eyes were full of dazzling red coral, which was also the main reason why he was able to see the red halo from the crack before.

The treasure ships he imagined were sunk to the bottom of the sea, and instead these priceless red coral trees appeared, which was a great surprise to him.

These red corals may have been growing here for thousands of years, and some have grown into towering trees, the tall ones can be three or five meters high, and the short ones are more than half a meter high.

Greatly, Japan is such a great place!

Japan is the most abundant coral country in the world, and the four most popular corals in the world's coral market are the most popular aka red coral, then sardine coral, and then white coral and black coral.

Among them, black coral has the lowest collection value, while red coral has the highest price, and the country with the richest red coral in the world is Japan.

Japan's red coral, also known as Acre in the international coral market, is currently the most popular species in the coral market.

Because the color of this coral is pure red and looks very festive, it is very popular with Chinese and Japanese, and even the rich people of all countries affected by the Chinese cultural circle in Northeast Asia are very fond of red coral.

Ancient Chinese emperors were very fond of red coral, and the emperors of all dynasties had hats decorated with red coral, and when the emperor of the Qing Dynasty celebrated his birthday, the officials of Fujian Province also paid tribute to the emperor with a whole red coral tree.

The emperors of Japan also liked this kind of red coral very much, and the emperors and nobles of Japan also had ornaments made of this red coral.

Because of this, the market value of this red coral is now very high.

Of course, this is mainly related to the current boom in China's antique entertainment market, red coral, pearls and amber, which are known as the three major organic gemstones.

In the early years, in China's antique entertainment market, people did not recognize this organic gemstone, at that time most collectors focused on traditional Chinese porcelain, calligraphy and painting, and traditional cultural toys, for red coral, amber and other treasures did not have a high degree of recognition.

However, since ten years ago, China's antique cultural toy market has gradually heated up, and more and more people are playing and collecting, and there are fewer and fewer treasures available for collection in the market.

Especially the boutiques, there are fewer and fewer.

Therefore, people who later entered the collection market had to find another way and began to explore new collection objects, so that some unpopular and unpopular people in the past also entered the eyes of people in the collection circle.

For example, those gemstone jewelry, diamonds, emeralds, sapphires, etc., which were not liked by people before, have begun to heat up in China.

But no matter how fast they warmed up, they didn't warm up as fast as the red coral.

Red coral, in recent years, the performance of the Chinese market can definitely be described as hot.

As early as more than ten years ago, when the red coral collection was just beginning to rise in the domestic market, at that time, the starting price of a gram of red coral, even if it was the top Akha red coral, was only between a few tens of yuan and two hundred yuan.

After ten years, it only rose to the level of two or three thousand yuan per gram of top-level red coral, but since 2010, the domestic collection market has heated up rapidly, coupled with the country's continuous issuance of currency, pouring water into the domestic financial market, which has led to the price of red coral soaring like a rocket.

In 2010, the price of one gram of top-grade Aka red coral was only more than 2,000 yuan in China, and by 2013, it had risen to 7,000 or 8,000 yuan.

By 2015, the price of this top-quality Aka red coral from Japan had risen to more than 20,000 yuan a gram, and the entire coral collection market was booming.

Even though red coral has risen to such a point, the wealthy who are willing to buy it still flock to it, and the reason for this phenomenon is also because as more and more people start to collect red coral, people will become more aware of the preciousness of this red coral.

It turns out that the reason why red coral is more expensive than sardine coral, white coral and black coral is also because their production is particularly scarce, almost a non-renewable resource, and if they are not produced, the less there will be in the world, so the more this thing is in the future, the more expensive it will be.

Red corals are generally found in the deep sea, and they grow in the range of about 20 to 200 meters below the water, and they also grow in places where the water temperature is moderate and there are rocky reefs on the coast below.

The process of its formation is that a large number of polyps first gather next to those submarine reefs, and then gather more and more, and finally when these polyps die, under the strong pressure of the seawater, they will gather together to form coral reefs, and then after years of accumulation, and the forging of seawater, finally can form the kind of red coral that we buy to play with.

And such a process of forming red coral often takes 300 years...

With the overexploitation of the ocean by people who are eager for quick success, not many people can wait for 300 years, so red coral can basically be listed as an endangered resource, and it can only be the kind that is exploited less and less.

Long before the red coral was mined out, under the water surface of the west coast of Africa, there used to be a more rare blue coral, but it is now extinct.

Because as long as there is a genuine product on the market, it basically doesn't have to wait for the auction, it will be swept away by those rich people.

Therefore, the current status of red coral in the collection market can really be described as having no tiger in the mountains and the monkey calling it the king.

But it's also true that red coral is extremely rare and will only get smaller in the future.

Moreover, the reason why the red coral market is expensive is not only because the stock of red coral is getting smaller and smaller, but also because the red coral is very difficult to mine.

Because this kind of red coral only grows in the range of 20 meters to 200 meters under water, and this range makes it extremely difficult for humans to mine this red coral by hand alone.

A diver with deep diving skills, even if the technology is proficient, but the depth that can dive is only ten meters to twenty meters, once the dive is deeper, it will cause internal organ damage due to strong water pressure, so it is almost impossible for people to rely on manual operation to mine red coral.

And the artificial equipment that can move within the range of 20 meters to 200 meters underwater is only a submarine, but submarines are basically special ships for the navies of all countries in the world, and few people in the world will be full of food and support, in order to build a submarine for themselves.

Even those rich people who have too much money and burn in a panic don't build a submarine for themselves to play, because this thing is so expensive that even they can't afford it.

The unique hull structure, coupled with the expensive cost of special maintenance and uncomfortable sailing experience, unless those rich people have a brain, will build their own submarines to show off.

The navy, which finally has submarines, will not be so brainless as to drive submarines out and let submarine members go underwater to collect red coral.

Even if red coral was valuable, it couldn't compare to the cost of a trip to the sea.

This is the main reason why the world's red coral production has become increasingly scarce in recent decades, because it is so difficult to collect.

Almost most of these red coral products on the market today are inventories mined by people more than ten years ago.

In recent years, due to the over-exploitation of coral resources, many countries with coral resources in the world have enacted strict laws to prohibit the over-exploitation and mining of red coral.

So at present, there are fewer and fewer red corals on the market, especially the newly picked ones, and today he Jin Muchen found such a huge mine here, isn't this God going to make him rich! (To be continued.) )
