Fresh water under the sea is not an anomaly in a special environment. It's just because it's relatively hidden and people don't know much about it that they find it novel.

In fact, there is a freshwater spring at the bottom of the Aegean Sea in Greece, with an astonishing flow of 1 million cubic meters of sweet fresh water in a day and night.

Dalian Bay in China also has a famous underwater spring - longan in the sea.

Freshwater resources are the fundamental elements of human survival, but the freshwater resources on land are very scarce, and drinking water is decreasing day by day, so that large-scale projects need to be built to regulate and drain water to alleviate the water problem.

Due to the limitations of vision, there is a huge misunderstanding in people's understanding, that is, fresh water is on land, and salt water is in the sea. In reality, the situation is very different, and the freshwater resources in the sea are not only far more abundant than those on land, but also in terms of quality.

This is the pure water produced in thousands of meters of rock formations, rich in minerals, and the so-called 100-meter ice springs in the Changbai Mountain, Baisui Mountain, and Himalayas.

In recent years, a large number of countries have begun to pay attention to this situation and use technical means to extract seabed freshwater resources to alleviate the dilemma of water scarcity.

However, the difficulty of seabed mining is very great, and the first seabed freshwater well has been built in the Shengsi sea area of China, with a depth of only 100 meters, which has consumed countless manpower and material resources.

This is the legendary distant water that cannot quench the thirst of the near.

The hundreds of freshwater springs in front of Lu Zheng's eyes, the flow of which flows day and night, are roughly estimated to be tens of millions of cubic meters, which is enough to form a huge undersea freshwater river.

It is absolutely impossible for humans to mine at a depth of 2,600 meters, even if it is very unlikely that it will be held for a few decades.

However, for Lu Zheng, the difficulty is zero.

According to the flow rate of these undersea springs, it can completely supply the domestic water of a large city, providing the most basic guarantee for the survival of human beings.

Building a city under the sea was an important part of the construction of the Dragon Palace.

The original idea was for Lu Zheng to provide a refining water source for daily use, but given the continuous huge amount of daily consumption, it was impossible to supply too many people. After all, he is a dragon king, not a water station.

And the existence of undersea springs fundamentally solves this problem.

The terrain of this basin is also very flat, which is more suitable for residential settlements. The remaining problem is how to build a city under the sea.

The seabed environment is harsh. The capacity of the Dragon Palace is limited, and it must be built artificially, which requires the support of advanced science and technology to achieve the desired effect.

As the saying goes, the Yellow River doesn't need to urinate, and Mount Tai is not piled up. The gourd is not strangled, and the fifteenth is not black.

There is a long way to go.

As a doer, you must be down-to-earth and control the size of your steps so as not to pull the dragon egg.

Inspecting this basin and conceiving a grand plan for the future, Lu Zheng's ears seemed to hear a melodious song: In 2015, it was an autumn, and a real dragon drew a circle in the East China Sea. Fabulously rise up a city, miraculously gather a mountain of gold......

Well, the noble and majestic dragon king sometimes makes up for it indiscriminately.

Lu Zheng is already a dragon monarch, and he can enjoy the glory and wealth to the fullest, eating the delicacies of the mountains and seas, drinking the jade liquid elixir, and the idle eggs hurt, and by the way, he took the dogs out to show off his might, and he liked a people's girl or something.

However, just like the great philosopher Zhou Xingxing said: if you don't have a dream, you can't dream. What's the difference with salted fish?

Building a city under the sea, even if Lu Zheng is a dragon monarch, is a little out of reach. But the more difficult the dream is, the more valuable it is to realize.

Stayed in this basin for two or three hours. It is estimated that the exploration of the shrimp soldiers and crab generals should have some results. Lu Zheng turned around and returned to the starry sky at the starting point, and when he left, he gave this basin a name, which was called Yongquan Basin (Special Economic Zone to be developed).

Under the blue starry sky composed of swimming fish, a group of shrimp soldiers has returned. Seeing Lu Zheng coming back, a small lieutenant of the shrimp soldiers hurriedly came up, hugged the tongs and said, "Back to Your Majesty, little Liu Laogen, at your behest to go to the southeast to explore." In the southeast of Yue a mile, there are major discoveries. ”

Say. Lu Zheng looked at the shrimp soldier with a bright shell, and said with a smile: "Wait a while, your name is Liu Laogen? Who gave you the name." ”

Shrimp soldier Liu Laogen said: "It was Liu Ming and Liu Duwei." ”

Lu Zheng said with a smile: "The name is good, it has a bit of the flavor of my name." Say, what's the key discovery?"

"Back to Your Majesty. The shrimp soldier said respectfully: "The small one found a seamount in the southeast direction, and in the belly of the seamount, there is a huge cave, the cave is spiral-shaped, and it is very spacious. On top of that, the small ones found a lot of large pearls inside. ”

"How big?"

Shrimp soldier Liu Laogen stretched out the shrimp claw, gestured and said, "It's bigger than the small head." ”

"So big?" Lu Zheng was a little surprised, the head of the shrimp soldier is similar to a basketball, there will be such a big pearl?

"Your Majesty, the little ones also let the sons and daughters bring back two. You see. ”

Shrimp soldier Liu Laogen got out of the way, and two shrimp soldiers swam behind him, and the shrimp claws were really holding two basketball-sized pearls, the color was milky white, the luster and texture were outstanding, and it had a very strong visual impact.

This is probably the largest pearl in the world!

"How many more?"

Lu Zhenglong's claws held the pearl, the touch was smooth and delicate, and it also contained a faint spiritual power, and he felt comfortable when he rubbed it.

For dragons, jade and pearls have considerable allure, and this influence is deep-rooted, so there is the so-called double dragon playing with pearls.

"How many more?"

"Well......" Liu Laogen's arithmetic didn't seem to be very good, and he was holding the shrimp whiskers and the shrimp legs vertically, and he gestured for a long time before he said dejectedly: "A lot, a lot." ”

"Lead the way, I'll see for myself. ”

"Yes, Your Majesty. ”

As the shrimp soldiers swam all the way to the southeast, they soon saw a continuous ridge protruding three or four hundred meters from the bottom of the sea. The middle part of the ridge forms a natural groove, and a swarthy hole is hidden in it, the size of a two-story house.

A large amount of sediment and other sediments were silted up in the cave, and they entered the cave and walked all the way, rotating in a clockwise shape as the shrimp soldiers said.

Soon, Lu Zheng saw a broken rock protrusion, and the shrimp soldiers roughly cleaned it up with shrimp claws, revealing half of the pearl that exposed the sedimentary layer.

The size is slightly inferior to the previous two, but the light is light blue, the shape is unconventional, the whole is dug out, the face Lu Zheng is amazed, the perfect circle, the circle is flawless, flawless.

Cleaning up all the way to the past, there are pearls constantly exposed, the shape is also varied, there are spherical, oval, oblong, the color is white, light yellow, light pink, light blue, a few are rare black and red, the number is about 40 or so.

The cave circled all the way, becoming more and more narrow, and this strange cave structure made Lu Zheng feel that he had entered a huge conch.

In the safe deposit box of the San Francisco Bank of the United States, a rare pearl weighing 6,350 grams and measuring 28 centimeters in diameter, resembles a human head, and is worth $4.05 million.

And the smallest of these pearls in front of you is the size of a golf ball. If it were in the world, I am afraid that its total value would be hundreds of millions of dollars.

Of course, the last thing Lu Zheng lacks is money, and the best use for him of these pearls is to act as decorations when building the Dragon Palace.

For example, put one or something on the toilet......

It's so capricious, it's so extravagant.

The dragon born of the sweat does not need to be explained.

The sedimentary layer in the cave is very thick, and if nothing else, there are many pearls hidden beneath the sedimentary layer. Lu Zheng flipped a few times with the dragon's claws and discovered the source of these pearls.

The sedimentary layer contains many large crustacean rocks covered with folded paths that resemble oyster seashells. The largest piece is the size of a wall.

As an ancient gemstone, pearls are derived from calcium carbonate mineral beads produced by pearl oysters and pearl oysters due to endocrine. The history is very long, dating back 200 million years.

To form such a huge pearl, these oyster shellfish need to be cultivated for at least thousands of years. If nothing else, this is the fossil graveyard of ancient oysters.

Pearl Cemetery.

Lu Zheng looked at this empty and spacious revolving cave, and suddenly his heart moved, the location of this cave is exactly surrounded by the sea ridge, it is very hidden, and the area is large enough, it can be used as a treasure house for the Dragon Palace to store treasures!

A treasure trove of conchs. (To be continued.) )
