"There are no three hundred taels of silver here, and the old king next door has never stolen it. ”

Lin Lan rented a yacht and went to sea, and came to a former tourist attraction more than 30 miles away from the Saint Le Nuclear Power Plant, showing a clear smile.

Many people have forgotten that there is also a blue hole on the Saint-Leux peninsula.

A deep blue round of water suddenly appears on the vast sea.

Viewed from above, it looks like the pupils of the sea looking from the depths of the earth, deep, mysterious, and eerie, and this peculiar natural landscape is called the Blue Hole.

In layman's terms, the Blue Hole is a huge deep hole in the bottom of the sea that suddenly sinks, and in layman's terms, there is a huge water bottle or kettle in the sea, which is closed inside and the opening is facing upwards.

Its name comes from the fact that when viewed from above the surface of the sea against the surrounding waters, this deep underwater cavern has a dim and mysterious dark blue hue.

The Blue Hole of Saint-Leux is hundreds of meters deep.

When divers dived inside to survey, they discovered that there was a severe lack of oxygen, probably due to the lack of water circulation to support marine life.

According to official records, this blue hole is basically a vertical cave.

The diameter of the blue hole is 160 meters, the diameter of the bottom of the cave is about 86 meters, and the widest part of the cave is 288 meters.

The connection between the Blue Cave and the open sea has not been observed, and there is no obvious flow of water in the cave.

Fishermen have been here for thousands of years, so there is a long legend about it.

There is a saying that it is a base for wizards to cultivate their self-cultivation and cultivate their magical power.

It is also said that this is the location of the eye of the sea, and the treasure of Zhenhai is hidden inside.

There is also a blue hole in the Song Kingdom, which is smaller in scale.

Legend is that the place where the Dinghai God Needle of Dayu ruled the water was located, and was later snatched away by the six monkeys, leaving a big hole in the sea.

Fifty years ago, the Blue Grotto on the Château de la Saint-Leux was a tourist attraction that attracted divers from all over the world.

But with the start of construction of the Saint-Leaux nuclear power plant, the Blue Hole was sealed off and designated as a no-go zone.

Lin Ran picked up the binoculars and saw the patrol boat and the outpost built on the coral reef, and circled the blue hole in a long distance before returning.

As soon as he dived into the water, he immediately activated Ren Zhen, and then told her about his analysis.

Ren Zhen said, "Are you saying that the two of us will add up to a certain threshold, so we are perceived by psychotropic mutants?"

Lin Chao responded as he went downstream.

"Yes, I'm like invisible after you're asleep, and those people can't see anything in front of me. ”

Ren Zhen thought about it and agreed with him.

"In the past, I still had to stay in human form at all times, and I had to sleep eight hours a day, and I didn't need to level up, so the key to the problem was that I needed more energy and more Gang Qi to upgrade, and after leveling up, I should be able to completely converge my breath. ”

"Hey, hey, hey. ”

Do you want to mention this every time, who doesn't want to upgrade, why don't you want to upgrade all the way here!

Lin Chao was no longer able to complain.

This is also the only place where Ren Zhen can replace Tiangang, and he never forgets to remind him, but she is much more verbose than Tiangang.

Lin Chao couldn't help but have a thought, it couldn't be the legendary menopause.

Sunlight is cast overhead, and the brightness is rapidly attenuated due to the obstruction of the seawater.

Ren Zhen reminded: "There is a boat on it, do you want to dive deeper?"

Lin Lan frowned, very unhappy.

"It's too much, why do you want to use the voice of a lifetime bamboo when talking to me!"

"Huh. ”

Ren Zhen's hehe is also a high imitation of a lifetime of bamboo.

Lin Lan wanted to roll his eyes and eat ice cream when he heard this, he really rolled his eyes, and then silently thought about how beautiful the world was and how fresh the air was......

After calming down, he got down to business.

"This time the target is the Saint-Le-Blue Cave, where I suspect that the spent fuel from the nuclear power plant is hidden. ”

"Yo, I know. ”

Now Lin Chao is strange, how does Ren really know about the lack of fuel, could it be that she has unconsciously developed new abilities, just like language talent.

Thinking of language talent, Lin Chao really has a headache, and Ren Zhen will imitate the voices of various people when he talks to him now.

One will be a lifetime, one will be a child, one will be Gu Siyu, one will be a priest, one will be a priest, all kinds of accents from all over the world, all kinds of tones, all genders and various characteristics, just want to act in Lin Chao's ears, which is annoying.

Ren Zhen said: "I know the cause of the Saint-Le-Blue Cave. ”

"Huh. ”

Lin snorted boringly, but he was still a little excited just now.

"Hmph, you know, it's knowledge. ”

Ren Zhen really likes to talk very much recently, imitating a certain respected host on TV who was blackmailed by "Qing Ren" to give a popular science lecture.

There are two types of internationally recognized causes of marine blue holes, limestone karst cave genesis and coral reef growth structure genesis.

"Actually, for a long time there was only one kind, and that was the former. ”

The so-called limestone karst cave is the calculus during the glacial period, due to the drop of sea level, the limestone was dissolved, and developed into a large cavity in the lower part, similar to a karst cave.

As the dissolution cavity grows larger, it causes the top to collapse and form a large hole with steep edges, called a sinkhole.

When the ice age ended, the sea level rose and the water re-poured into the sinkhole, which became known as the Blue Hole.

This type of blue hole has a large number of stalagmites, stalactites, etc., and fissures are developed.

Often form a number of channels connected with the outer seawater, the water body in the cave and the outer sea water have a certain exchange, and there may be a large number of products of erosion and collapse of the limestone wall or the top of the cave at the bottom of the cave.

"The world's well-known limestone caves have so-and-so, so-and-so, so-and-so, ......"

The coral reef growth structure was proposed in the late 90s, such as the Saint-Le-Blue Cave that they were about to explore.

The process is that since the Holocene, 10,000 years ago, coral reefs in this area have grown rapidly.

Many of the smaller, fast-growing spikes form spinous protrusions that clump together, eventually forming near-circular holes.

The internal water environment of the cave has a significant impact on the growth of corals, while the external water environment is conducive to the growth of corals, and gradually develops into a blue hole with a larger water depth.

"If you look closely, you can see the difference in color between the inside and the outside. ”

There are no stalagmites, stalactites and other products in this type of blue hole, there is no channel for exchange with the outer sea water in the cave, and there is coral sand at the bottom.

Because blue holes are usually hundreds of meters deep and suffer from severe oxygen deprivation, they cannot support most marine life.

There is no disturbance from the activities of modern organisms, which is conducive to scientists studying ancient fossil remains and other sediments here.

Therefore, the Blue Hole is known as the last legacy of the secrets of the universe.

"Ladies and gentlemen, we will talk so much about the types of blue holes today, and now I will ask experts to talk about the precautions for treasure hunting in the sea. ”

Ren Zhen chattered non-stop, like a surging river.

Listening all the way and swimming all the way, Lin Chao already felt a large and hard reef, like a wall.

He paused to rest and said expectantly, "I hope there's something in there." ”

Ren Zhen seemed to understand what he meant, and changed to a sunny and hearty male voice.

"I spent my childhood abroad because of my mother's work. Those monarchies of the Maple Leaf Country, the Boda Country, and the Star Moon Continent...... There is such a proverb in the Star Moon Continent, no matter how you travel, there is treasure that you can't get. ”
