Fang Hong finally swam to the side of the red coral: "Brother gun, the expert reminds you to be careful, the edges and corners of the red coral can be cut through the diving suit." Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

Fang Hong gestured OK.

Red corals are connected from a distance, and they can only be seen branching up close.

"Coral is a very particular living environment, especially red coral, which is very rare in the world. ”

"The average polyp is only half a millimeter to two centimeters in diameter, with eight pinnate tentacles that, when opened, look like eight-petaled snowflakes that open and contract in the sea to catch plankton. Red coral basically only grows in the deep sea in tropical areas where the sea temperature is higher than 20 degrees, about 100 to 1,000 meters of the seabed, red coral is an organic gemstone, often used as a carving material, also has medicinal value, due to a large number of mining, has been listed as a national first-class protected animal. ”

"Comrade experts say that the number of red corals here may have exceeded the total number in the Taiwan Strait of our country. ”

In China, only the Taiwan Strait and a very small number of areas are scattered here, and there are such a large number of coral reefs and live polyps, which are directly related to being far away from the shipping lanes and deep under the sea eyes.

Under the sea, coral groves are generally the most biologically abundant areas, and a large coral reef is basically a separate biosphere that can support other carnivorous organisms in a large area of the sea.

Tang Yixin was anxious: "Brother Gun, tell you to be careful, the divers in the other direction have damaged a coral, it seems that the corals here are very fragile." ”

The body size of corals is actually calcium, and it should not be fragile.

But in fact, nature is so amazing.

In my country's CQ, there is one of the world's largest sinkholes. There are still tall ferns that disappeared with the dinosaurs as early as the time of the dinosaurs, as well as trees and trees that fell from the holes, which are characterized by growing straight and tall, but very fragile.

The reason is that from an evolutionary point of view, they have always longed for sunlight, and there are no large animals in the closed environment, so they don't need to grow so tough, there is no wind, no rain, no thunder, so the extremely hard plants in the outside world are vulnerable to the sinkhole.

I'm afraid that's the case here.

Plankton also like to live in the deep sea, but green algae need to grow in sunny areas.

As a result, the polyps here have begun to grow upwards in order to contact more plankton, and the dead polyps are not like other seas that accumulate layer by layer, but continue to superimpose upwards, and up to now, live polyps are already very vulnerable, and the coral reefs that have just been born are also particularly fragile.

Fang Hong cautiously moved forward, trying not to touch the coral reef.

Small fish weave through the coral reefs.

Parasitic crabs and shrimp also climb on the exposed reef.

The giant searchlights didn't affect them too much.

As Fang Hong walked up, he was shaken by something, immediately stopped, turned over in the water and swam back, and the destination was actually the base of the giant red coral in Baoshan.

"Brother Gun seems to have found out again, Sister Wine. ”

"yes, Brother Gun turned around. ”

Tang Yixin: "I don't know, I'll know when Brother Gun finds it." ”

Fang Hong was clearly shaken by something, it was in this direction.

At the bottom, Fang Hong's legs were on top, and his upper body was close to the bottom of the sea, looking carefully.

In a piece of fine sand, a transparent thing appeared, Fang Hong cut through the fine sand and observed it carefully.

Next to Tang Yixin, the expert comrade took the microphone: "You cut the sand a little bit to see if it's a creature or a mineral." ”

What can emit light or reflect light is either living beings or high-quality minerals, or gemstones.

Fang Hong threw aside the fine sand and saw a cylinder with a smooth surface but divided into six sides, each side of this thing was very flat, but the edges and corners between the faces were clear.

"Good looking standard crystal!" Comrade expert: "You align the light and look at the color."

Under the sea, it's normal to see things and see the wrong color, but it's different when exposed to strong light.

Transparent things can transmit whatever light they can pass through, and what color they are.

The bright light passed through, leaving a purple halo on the sand behind it.

"Amethyst?" the expert was surprised: "Impossible?"

"Amethyst is mainly silica, hard texture, high refractive index, and amethyst generally has water mist or ice cracking. ”

Fang Hong continued to throw sand and gouged out the whole bead.

Because crystals are basically slowly grown in underground rivers or underground, or condensed little by little, the body shape will be smoother and neater, and the number will be relatively large.

But amethyst is produced through volcanic eruptions, which are generally not so regular and need to be cut, and the world's largest amethyst weighs only one catty, which has to be several kilograms, and it is at the bottom of the sea, and there is no trace of volcanic eruption.

"No, this should be a magma room in a volcanic crater, and it's normal to produce amethyst, but this one is too regular!"

Fang Hong gestured to the camera, and dug up the fine sand next to him, another one, and five of them grew into one!

Subsequently, crystals continued to be pulled out by Fang Hong in this area.

The expert comrade sighed: "Fortunately, amethyst is the most worthless gemstone, and if there is such a large pile of diamonds, the country must send a fleet to guard here." ”

But what he didn't expect happened.

Fang Hong dug out the crystal again, but it was not an amethyst, but a titanium crystal!

Two other divers have also made discoveries, including tourmaline, red rabbit hair crystal, ametrine and so on.

In addition to these expensive varieties, there are also some hairy crystals, transparent colorless crystals, and red crystals are found.

The crystals here are diverse and very numerous.

"Damn, did Brother Gun dig out the South China Sea Crystal Palace!"

Legend has it that the place where the dragon king lived was built with crystal, so it was called the Crystal Palace.

Red coral is everywhere here, which is super rare, and there are so many kinds of crystals, covering almost all kinds of crystals on the earth.

However, the production conditions of various crystals are also different, how can these crystals be concentrated here?

This is a huge crystal vein, and with the addition of red coral gemstones, it is simply immeasurable, much more expensive than a mountain of gold of the same volume!

"Sister Jiu, don't talk nonsense, saying that Baoshan is Baoshan, this is too scary!"

"It turns out that the South China Sea is a cornucopia, not long ago a large amount of combustible ice was discovered, and now crystal mines have been discovered, most of the crystals found before were in underground rivers and underground, I am afraid that it is also out of the unknown of the seabed, and now these are found on the seabed, which is not surprising, after all, the sea area explored by human beings is less than three percent of the earth's sea. ”

Fang Hong couldn't speak under the water, that jumping foot.

If these are found in foreign waters, then the special thing is just one word, dig.

However, this is a domestic sea area, first, the state has strengthened the protection of various gem mines in recent years, and second, the domestic mines belong to the people, that is, state-owned assets.

Fang Hong couldn't sneak any of them away.

"Look at Brother Gun's expression, a standard money fan. ”

Tang Yixin: "Phew, such big glasses, biting the snorkel, can you still see the expression?"

Comrade expert: "This is a big discovery, it is necessary to report it, but I didn't expect that there would be such a big discovery on the first day of the water." ”

On this day, this sea eye was officially named, the Dragon's Den of the South China Sea.
