After everyone had a good swim at Crescent Reef, the time came to around 3 p.m., and they set off for the last of the three major attractions of the Shaye Islands - the Blue Sea Cave.

Located in the shallow waters southeast of the Shaye Islands, the Blue Hole is actually an ocean blue hole, which is a huge, abruptly sinking "deep hole" on the shallow ocean floor, and its name comes from their dim blue hue relative to the surrounding waters.

The cause of the formation of the Ocean Blue Hole can be traced back millions of years to the Ice Age, when the cold climate caused water to freeze in the ice caps and glaciers near the Sha Coconut Islands, which led to a significant drop in sea levels. At the same time, due to the mutual erosion of fresh water and seawater, many karst cavities have been formed in this calcareous area. The location of the blue hole was also a rock cave, the hollow and loose calcareous dome collapsed into a circular opening due to gravity and earthquake and other reasons, it became a shaft, and so on until the ice and snow melted, after the sea level rose, the seawater poured back into the shaft, thus forming a peculiar landscape of the lake embedded in the sea, because of the special structure of the cave entrance, on the one hand, the sunlight can enter the cave from the hole, on the other hand, it is reflected from the bottom of the water in the cave, so the sea water in the cave is a crystal blue, mysterious, even the rock in the cave has become blue, so it is called " Blue Hole".

The first explorers of Charharrow named the blue hole "Duo Kulas", which means "eye of the sea".

Later, when Charhatro tourism was developed, it was changed to an easy-to-understand one: blue sea and blue cave.

When visiting the Blue Grotto, you must choose the right time: first, the weather must be sunny, and second, there must be no wind and waves.

......

When they reached the sea area around the Blue Sea Cave, it was at low tide, and it was not allowed to take a boat to the Blue Sea Blue Cave at this moment, because the sea level was low at low tide, and the corals in the shallow sea were very close to the sea surface. Ships sailing on it can destroy these precious corals if they are not careful. At low tide, if you want to get close to the blue sea and blue hole, you need to take a flying machine to get there from the air, or you can swim there on your own.

Both of them have professional diving training, and this kind of shallow water diving is not a problem, and they can also enjoy the ocean scenery along the way.

There are also many coral communities around the Blue Cave, with a variety of colorful tropical fish, turtles, dolphins, jellyfish, sea urchins, and even large mammals, such as manatees, cruising nearby.

When they swam to the blue sea and blue hole, there are already a lot of people gathered around the blue hole, there is a circle of glass platforms at the edge of the blue sea and blue hole, which is a place for tourists to rest, of course, they will be taken away by the aircraft when the tide is high, and they will be brought back at the next low tide.

At low tide, because the boats can't enter, and because of the special environment of the Blue Hole, the tourists who come to the Blue Cave at this moment are generally here to dive.

Jumanji is also very simple, just wear simple diving equipment (i.e. a wetsuit and oxygen supply) to see how deep you can dive.

This game is simple to say, but it is more dangerous to play, because the depth of deep diving is not a few tens of meters, but hundreds of meters.

The diving depth of ordinary people carrying simple diving equipment is about 40 meters, and the depth of 200 meters is exceeded by specially skilled divers.

But now the times are different, most of the people who come here to do blue hole diving are genetically strengthened people, their bodies are stronger than ordinary people, and their adaptability to the environment is also stronger, and they can naturally dive to deeper depths.

Of course, you can't use armor for the challenge, you can only rely on your own strength. There are many retired or active soldiers who have come to challenge, and their strength is generally B-level, and there are even some A-level above, and there is even an S-level martial god who has challenged anonymously, but they have not reached the bottom of the blue sea and blue hole without exception.

Maybe the SS-level Martial Gods can do it, but the SS-level Martial Gods are the top combat power of various races, and they won't come to do these things.

So, until now, no one has ever reached the bottom of the blue hole with simple diving equipment alone.

......

The main reason for the difficulty of deep diving is that as the depth of the dive increases, the pressure of the sea water will continue to increase, because ordinary diving suits cannot offset the pressure of sea water on the human body, so you need to use your body to carry it.

Forcibly diving to a depth that you can't cope with is causing the pressure of the sea water to cause great damage to your body. Some people are bleeding immediately after diving to the surface, which is very frightening, because their internal organs have been damaged by the weight of the sea.

There are even a few people who die a year because of deep diving, and there are not a few who leave sequelae.

Therefore, before diving in the Blue Cave, you must sign a waiver agreement, which will inform you of the dangers of participating in this activity, and if you insist on participating in it, resulting in danger, the tour party will not be held responsible.

......

And in addition to the physical pressure, there is also a huge psychological pressure.

Because the improvised diving equipment does not show the depth of the dive, the person concerned will not know how deep they have dived and how much they need to dive to reach the bottom.

In the dark seabed, this kind of unknown can cause a lot of psychological stress.

It takes a lot of courage to win.

Challenge yourself, this is the brave game.

......

However, the rewards of this game of Jumanji are very interesting, and it does not give bonuses directly, but prizes.

The prize needs to be obtained by yourself, and the prize is a number of basketball-sized crystal balls, each of which contains a bottle of wine, which are precious fruit wines that have been aged for hundreds of years. The deeper these wines are, the higher their value.

The value of the lowest bottle of these wines is more than 200,000 star yuan, and it is said that the bottle hidden at the bottom of the blue sea blue hole is worth several million star yuan, and it can be said that the reward is very rich.

If the challenge is successful, in addition to the prizes, there is also a glory, and those who successfully get the fruit wine in the blue sea and blue cave will also be officially placed by Char Haro to prove that you have completed the game.

In addition, the information about the winners of the game will be hung on the official honor roll of Xia Haro, so that people who travel later can see it, which is a high honor.

......

Because of the difficulty, danger and generous rewards of this brave game, it has a huge charm that attracts people from all over the universe to participate in this game regardless of the danger.
