Olidia Island was formed by the long-term movement of the seafloor crust.
And the Twin Mountains on the island.
should be the most frequent area.
has experienced thousands of years of evolution.
As the altitude increases.
The mountains gradually rose from the ground.
This way.
The geological environment here will naturally be different from other places.
among them.
The most intuitive performance.
I am afraid that the surface rock layer has super strong water storage capacity.
Otherwise.
In the middle of the mountain, such a spectacular scene will never appear.
Speaking from geological factors.
Shuangzi Mountain should be a relatively complete mountain in the early stage of island formation.
led to the culprit of this kind of first-line wonder.
is most likely related to this natural spring.
At first, this fountain was very weak.
But after thousands of years of evolution, coupled with the push of the crustal movement.
The spring water shows in the forest.
Killed a blood path from the mountain.
Split such a behemoth into two halves!
Finally, this ancient wonder was created!
The formation of the first line of heaven was regarded as a mysterious and difficult puzzle in the ancient times when productivity was not developed.
but in fact.
But this is not the case.
Most of the "first-line sky" is the result of continuous expansion of fissures or joints in the rock.
The original vertical fissure is a product of the cracking of the internal strength of the rock.
But later, with the sun frost, wind and rain, spring erosion.
This fissure will gradually expand over a long period of time.
Forms a narrow, upright natural passage.
Of course, there are some "first-line sky" formed by faults.
Faults and fissures are different in that the rock layers on both sides of the rock have up, down, left, and right displacements after cracking.
The Twin Mountains in Orlydia belong to the former.
I thought that for the primitive people who lived here for a long time, they naturally did not understand these things.
I just feel very magical.
is very spectacular.
Then, after the ruling class's rendering and advocacy.
People naturally associate it with gods.
Therefore, it is naturally no surprise to build the temple in the mountain.
Water is the source of life.
has been living by the water since ancient times, and primitive people are no exception.
looked at the mountain spring in front of him.
Lu Yu talked to the audience with his thoughts.
'S words reveal the awe of this magical land.
Today, such a spectacle will be amazing.
Not to mention that ignorant era.
"Brothers, really amazing."
"This spring has been spewing for tens of thousands of years."
"The vitality of Oulidiya Island is so tenacious, thanks to it. The only regret is that no one has lived here except me..."
finished, Lu Yu jumped off the rock.
walked closer.
Closely observed the eye that nourished the island for a long time.
Soaring water column.
Its momentum is unstoppable.
within a few tens of meters.
seems to rain.
The visibility is scary.
The noisy sound of water almost covered up everything.
The scenery is exceptionally magnificent.
Who would have thought that in the depths of the wild Pacific Ocean, there is such a world wonder?
a time.
The barrage in the live broadcast room also came like a rush.
All the audience were shocked by the scene before them.
"Good beauty!"
"Take a photo with me!"
"Thanks to the anchor!"
"Is it possible to develop into a scenic spot?"
"With the popularity of the feather god, it is estimated that the value of the entire island may rise to astronomical figures after the live broadcast ends!"
"I want to buy shares!"
"I have a piece!"
...
stayed in Quanyan for a while.
Lu Yu continued to move forward along the river channel.
is here.
The flow of water has changed dramatically.
From the initial countercurrent.
became downstream.
Until the end of the first line of sky, did not completely disappear.
walked forward for a while.
Unconsciously.
The light in the mountain road.
suddenly dimmed.
Many vines climbing plants fall from the top of the mountain to the ground.
The field of vision is extremely poor.
If you are in the jungle, you might get lost if you are in this situation.
Lu Yu can only **** while walking forward stumbled.
After a while.
It was not until the area was crossed that the light was bright again.
In an instant.
More than an hour passed.
The end of the mountain road.
suddenly shot a strong light.
See here.
Lu Yu was very happy, facing the camera and said: "In front, it should be the end."
"Let's take a look."
"Unsurprisingly, the other end of the mountain should be the northern shore of the island."
The sound of the speech landed.
He accelerated his pace.
Three steps and two steps.
trot all the way.
Not long.
The road has come to an end.
greets the goal, is a very messy reef heap.
stands on the shore.
The monstrous waves and the roar of the sea breeze.
is endless.
It's been a long time.
Far from the sight.
The vast ocean and the sea are calm and without waves.
Indifferent.
randomly found a highest point to stand up, Lu Yu looked around.
Nothing special was found.
However, because of the terrain, there is a path leading to the top of the mountain.
From here up the mountain, you can reach the summit of the Twin Mountains almost effortlessly.
So.
Lu Yu immediately acted.
along this mountain road, came to the top of the mountain.
this time.
Because there is no weight on the body.
climbed up, very relaxed.
It was not even twenty minutes before he stood at the commanding height of the whole island.
...
...
...
Gemini is the absolute commanding height on the island.
stand right here.
As long as you want, the whole island can be in your sight.
Overlooking Shino.
The drone hovered aimlessly over Lu Yu's head, photographing this scene.
Before coming to Olidia.
Lu Yu climbed many mountains.
The steepness is incomparable to the west face of Huashan Mountain.
In terms of altitude, Everest is also far ahead.
but don't know why.
This hill, which is a few hundred meters high, gave him a lot of different feelings.
"My friends, this is not the highest mountain I have ever climbed."
"But it must be the most meaningful mountain I have ever climbed."
"Along the way, stumbling."
"Until today, I have clearly seen the whole picture of the island with my own efforts. Although my challenge is not over, there is no doubt that this is another kind of conquest and comprehension."
"At this moment, I learned about Oridia, its history, its past and present, and the magical island that was once brilliant and now lonely."
looked at the island where he survived for more than a month.
Lu Yu has mixed feelings in his heart.
Confused thoughts.
I don't know how to express this feeling.
can only say.
not easy.
is really not easy.
...
Standing on the top of the mountain.
looked at the meeting.
Lu Yu recovered.
Want to go down the mountain following the previous road, and then return to the camp to end his trip to the North Shore.
However, two steps have not been taken yet.
left side of the body.
a raised rock suddenly caught his attention.
See something strange.
He immediately poked his head and looked at it.
Results.
Take a look.
The back of the rock.
Actually don't have a hole in the sky.
Do not know why.
There is a small cave there, which leads directly to the mountain!
Because the light is too dark.
lay on the ground and looked inward, unable to see the specifics inside.
can only see a little light.
looks.
should be Shuiguang.
narrowed his eyes, Lu Yu looked attentively for a while, then murmured:
"Bros..."
"There should be a dark river below."
Under the river.
is also known as "Fu Liu".
Due to karstification, in the karst caves and underground passages formed in large-scale limestone areas, it has the main characteristics of river flow.
Gemini Mountain is in line with the geographical origin of the Underground River.
The abundant groundwater circulation allows a natural spring to spout day and night.
all benefit from this.
Therefore, it is not surprising that there are rivers in the mountains.
Secondly, the high temperature and rainy tropical climate is also conducive to the formation of the dark river.
In the live room.
After listening to Lu Yu's words, the audience launched the barrage one after another:
"Underwater?"
"Leap of faith, ready!"
"Lying trough, isn't Yushen jumping from here?"
"If the anchor dares to jump, today I will give him ten super fires!"
"I brush twenty!"
"Jump down, do you want to die?"
glanced at the barrage in the live broadcast room.
Lu Yu smiled.
Faced with the audience's vomiting, they waved hands repeatedly:
"A few hundred meters, even if there is water underneath, jump to death."
"Not to mention a few hundred meters, even if you jump into the water from a few tens of meters, the lethal rate is as high as 90%."
"At this height, there is no difference between the water surface and the ground, ranging from a swollen nose to a blue face, and a heavy death on the spot, it will definitely die."
"In 2016, a train in North America exploded on a dozen-meter-high cross-continental bridge. At that time, a white passenger in the exploded compartment smashed the car window in order to escape and wanted to jump to the river. In the end, although this guy managed to escape, he also lived in the ICU for the first time and barely survived. He may spend the entire second half of his life in a wheelchair."
"So, don't do this for non-emergency incidents. Ordinary people without professional training can already be so dangerous by jumping a dozen meters, let alone a height of a few hundred meters, unless you live impatiently... "
The dark river in the cave.
There is nothing special about .
But in the dark.
In addition to the passing river, through observation, Lu Yu also noticed a very imperceptible detail.
The lower left of the line of sight.
is the deepest part of the inner wall of the cave.
seems to be shining.
However, because the light is limited, I can't see anything at all.
"Brothers, there seems to be something below."
Adjusted the lens of the drone, Lu Yu focused his perspective on the cave, trying to show the audience his new discoveries.
However.
is too far away.
Even if the lens is elongated, the audience is confused.
Seeing this, Lu Yu immediately turned on the night vision function of the drone.
controlled it with his mind, let it slowly fly into the cave, and surveyed it.
The inner wall of the cave is very humid, with many drops of water condensing.
densely packed.
If you don't read it, it's good.
It's enough to have a goose bump.
is close to the cave wall.
Drone all the way down.
After a while, he came to the bottom of the cave.
On the screen.
The depth of the dark river is unknown.
But the flow rate is extremely fast.
also takes up a lot of space.
went all the way down, I do not know where to go.
"The spatial distribution of dark rivers is controlled by lithology, geological structure and drainage datum."
"Underwater is often developed at the axis of strata folds, fissures and fractures, the contact of soluble rocks with non-soluble rocks, and near the drainage base level."
"However, the dark river has its own supply, runoff and established drainage system. After a long period of geological changes, an extremely well-developed underground river system is usually formed. Underground rivers and volts are not only important water sources in karst areas, but in some limestone mountains. There are also many of them."
Underwater development and its morphology are often controlled by geological structures and fissures.
morphological characteristics are very complicated and disorderly.
Some are dendritic.
Some are jagged.
Some are linear.
There is also a mesh.
But anyway, in this huge groundwater system, each underground river will have its own recharge and discharge channels.
Multiple unconnected dark rivers can also be developed in the same aquifer.
Therefore, it is very likely that the river you see in front of you is the most insignificant one in the Oridia groundwater system.
Watch the flow rate.
Preliminary estimates.
The underground drainage area of the underground river is at least 1000km.
In other words, it is not just the Twin Mountains.
The entire north shore, even somewhere on the west coast.
There may be similar underground underground rivers!
Lu Yu explained to the audience.
The drone is flying quietly along the river.
There was almost no sound except the water flow around.
On both sides of the river, the space is very cramped.
At most can accommodate one person walking sideways.
in the dark.
The live broadcast picture followed up slowly.
arrived in a blink of an eye and found a glowing spot.
Extended the camera and looked up.
It turns out.
The glowing spot Lu Yu saw was not something else, but a decaying metal box.
The pattern on the box is extremely retro.
was covered with rust.
But even so.
can still see the general appearance and the pattern carved on it.
Observed for a while, Lu Yu in the black and white night vision lens.
vaguely saw a very clear balance sign.
While fixing his eyes, Lu Yu swallowed and shook his head and sighed:
"Brothers, did you see that sign?"
The voice of was not finished.
The drone's lens began to focus.
Next second.
In a moment, the barrage in the live broadcast room flooded like a tide:
"Lying trough!"
"Isn't this the mark on the gold coin?"
"Nima! What happened?"
"Brothers, what a big deal!"
"I get together..."
Lu Yu nodded gently.
Then, he said:
"Yes."
"This is a sign of the Pirate Utopia..."
"It seems that this treasure chest left at the bottom of the cave should also be related to Avery."
"Brothers, if I'm right, Oridia, this uninhabited island hidden deep in the Pacific Ocean, is probably the thief of the century, Avery's last hiding place..."
