let you take over the zoo, you drive the animals crazy

More precisely, due to the synchronous occurrence of the submarine vortex here, the condensed icicle becomes a hollow icicle that reaches the bottom of the sea.

The probability of these two miraculous natural phenomena meeting is less than one in a million.

"Could they go down from here?" Looking at Yang Lin, he had a bad guess.

As soon as this guess was made, Goudan Gousheng next to the ice cave started barking wildly.

As soon as they called, Yang Lin knew he had guessed right.

"How dare they do that?" While sighing helplessly, he prepared to go deep into the ice cave.

No way, who let it be my own parents inside.

And he also had a premonition that there might be other secrets hidden under this ice cave.

After so many adventures, this is the first time that Yang Lin is so uncertain.

For this reason, he also brought all the things that might be used below.

Light source, power supply, emergency food, medicine, oxygen, and even a detonator given to it by the staff of the scientific research station.

After taking all the supplies, Yang Lin looked at the animals beside him.

To be exact, it was the arctic fox who had awakened the talent of luck.

"I'll just bring you this time, I hope you can bring me good luck."

After saying this, Yang Lin tied the little guy in front of him with a backpack buckle.

"OK, there shouldn't be anything missing this time."

"ready to go!"

After pumping himself up, Yang Lin walked towards the edge of the ice cave.

While taking a deep breath, he also turned on the action camera above his head.

In the next second, he closed his eyes, and then took a light step forward.

The moment his foot stepped on the air, his back was attached to a layer of ice, and then he felt like he was on a slide.

After a scream, Yang Lin's figure disappeared in this mirror plain.

Chapter 436 Underground Lake, Era of Giant Beasts

In the ice cave, Yang Lin claimed that he was not shy, but after skating in a narrow and closed pipe for several minutes, he still felt serious discomfort on both physical and psychological levels.

If there is such a slide in the world, it is estimated that most people will not want to challenge it.

More importantly, this slide is in danger of breaking at any time.

Once it breaks, he will fall into the Arctic Ocean.

Fortunately, what he feared did not happen.

After another few minutes of gliding, he could already clearly feel the flow of air.

This also means that the most terrifying slide in history is coming to an end soon.

Sure enough, shortly after he had this idea, an exit appeared in front of his eyes.

Immediately Yang Lin tightened his body core to avoid the impact after landing.

But what surprised him was that what was waiting for him was not solid ground, nor mud under the sea, but a plop.

That's right, he fell into another body of water after falling from the Arctic Ocean.

When the cold water soaked his clothes, he felt as if someone had skinned him with a knife.

At the same time as the whole person was excited, he immediately put the little arctic fox on his chest on top of his head.

After putting it away, he took out a waterproof flashlight from his pocket.

When the strong light of the flashlight illuminated the water, Yang Lin was immediately stunned by the sight in front of him.

Looking around, there is water all around, and the top of the head is like a rock layer.

This means that his current location is an underground cavity, an underground cavity under the Arctic Ocean.

Seemingly thinking of something, Yang Lin casually tasted the surrounding water.

In the next second, his expression changed subtly.

"It's fresh water. This is a freshwater lake."

Although he had learned about this a long time ago through the legends of the Inuit, he still felt a little fake when the facts were in front of him.

There is a freshwater lake hidden under the sea, who would believe it?

However, thinking of the inferences in the Nature Magazine, Yang Lin guessed that this might be the most primitive Arctic Ocean, which is the Beiming mentioned in Zhuangzi.

Due to some special geological changes, this lake called Beiming became underground from the ground, and the seawater of the Atlantic Ocean flowed above it and became the later Arctic Ocean.

"The world is really big, full of wonders. If this is a writer, I'm afraid he wants to write a science fiction work that is not inferior to Journey to the Center of the Earth."

While sighing, Yang Lin looked for the direction in this underground lake.

However, because the lake was too vast, after searching for a long time, he couldn't find out why.

In the end, he pinned his hopes on the little arctic fox above his head.

"Little guy, tell me where to go, and I'll go there, okay?"

Hearing Yang Lin's words, the little arctic fox pointed its front paws somewhere in the underground lake just by turning its small eyeballs.

"Okay, let's go in the direction you said!"

As soon as the words fell, Yang Lin started swimming in the direction pointed by the little Arctic fox.

After a period of adaptation, his body gradually adapted to the icy lake water, so he did not swim slowly.

Fifteen minutes later, when his flashlight shone forward, a black land appeared in his field of vision.

When he saw this black land, Yang Lin's mood changed again.

First, there was the same lake as in the legend, and now there are islands in the lake that are exactly the same as in the legend.

This had to make him suspect that the ancestors of the Inuit had really been here, otherwise how could he be so accurate.

"Isn't this really the palace of the goddess of the ocean? It won't be so mysterious."

While admonishing himself to believe in science, Yang Lin's heart was pounding.

But the current focus is obviously still on the island in the lake, and his lost parents are likely to be on it as well.

So at the moment, he couldn't control that much anymore, and swam desperately towards the island with his arms free.

Another 5 minutes passed, and when his legs stepped on the land again, the sense of security that had disappeared for a long time also returned.

And at this moment, two rows of footprints on the land immediately caught his attention.

These two lines of footprints are one big and one small, one deep and one shallow, obviously they come from two people with huge difference in stature.

The big one is about a size 45, and the small one is about a size 38, which is exactly the size of his parents' shoes.

The moment he realized this, Yang Lin became excited.

He had been worrying about his parents' accidents from the whole journey to the last second. Now that he saw the footprints of the two of them, he could finally relax a little.

"No, I have to find them quickly. It should have been many days since they landed on the island, and they are injured again."

After the excitement, Yang Lin quickly returned to reality, and followed the footprints left on the ground to search for it on the island in the middle of the lake.

Unlike the islands outside, the islands here are bare everywhere, without any plants or animals, only gravel and mud, just like the original appearance of Blue Star.

It is also true that the footprints left by his parents are particularly obvious.

After walking for more than ten minutes, two tall and pale stone pillars appeared in front of him.

Looking at these two towering stone pillars with a slight curvature that did not seem to be formed naturally, Yang Lin suddenly murmured in his heart.

"Why are there two pillars here? Could it be that there is still an ancient human civilization here, or that the ancestors of the Inuit lived here?"

This conclusion was immediately overturned by him as soon as it came out.

The geological change in the Arctic occurred more than 2000 million years ago.

The blue star 2000 million years ago was still in the Miocene, when the north and south poles were not covered by ice and snow.

The oxygen content on the blue star is not comparable to what it is now. There are giant beasts everywhere on the entire planet, and the ocean is the most. It is not an exaggeration to call it the era of giant beasts.

At that time, the ancestors of human beings could not tell which tree to pick bananas on, and they were caught by giant birds within a second if they dared to go down the tree.

Just when Yang Lin was about to start researching what material these two huge stone pillars were made of, his corner of the eye glanced at the back of the giant pillars.

Just one glance at the flashlight in his hand and he almost lost his grip.

Following his gaze, he saw that not far behind the stone pillars, two rows of identical stone pillars in symmetrical divisions extended from where he was now to the place where the flashlight light source could not reach.

Seeing these two rows of neatly curved stone pillars more than ten meters high, Yang Lin realized at this moment that these were not artificially carved stone pillars, but two rows of ribs of some kind of super large vertebrate.

Judging from the bone fossils within his sight, he couldn't even imagine the size of this super-large vertebrate during his lifetime.

Chapter 437 Meeting

Yang Lin thought that seeing the creature that looked like a real dragon at the bottom of the dolphin island was old enough.

But compared with the bone fossil in front of me, the fossils at the bottom of the pool are not enough to see.

The length of a single rib has reached an astonishing 50 meters. According to the proportion, its length may even exceed hundreds of meters.

This can no longer be described as a giant beast.

After being shocked, Yang Lin quickly continued to walk forward, counting while walking.

When he reached the end of those fossil pillars, he finally counted the number of these stone pillars.

There are 13 pairs and 26 ribs in total, which is in line with the number of ribs in general mammals.

The same is true of whales, of course.

Therefore, Yang Lin has reason to believe that the owner of this giant skeleton should be a giant whale living in the ancient Beiming.

Only in water can such a giant be born. If it is on land, its huge body will directly crush itself to death.

"It's unbelievable that the Kun actually existed. How did Zhuangzi know about it, and how did the ancestors of the Inuit pass it down from generation to generation?"

For a moment, Yang Lin's heart was full of question marks.

But what made him even more curious was the era of behemoths 2000 million years ago. He even suspected that the behemoths of that era had created their own civilization, but this civilization had disappeared in the long river of history.

Just when Yang Lin was fascinated, the little arctic fox in his arms suddenly let out vigilant calls.

After hearing the cry, Yang Lin's first reaction was that there was danger, so he shone the flashlight forward.

In the next second, a strange building similar to a temple appeared in front of him.

With a pale appearance and a peculiar shape, a dark and deep portal in the middle leads to an unknown location, just like the ice cave before.

"Is it really the temple of the goddess of the sea?"

After careful observation for a while, Yang Lin overturned his own conclusion.

"Look at my head, this should be the skull of the giant whale just now, but this shape really looks like a man-made building."

While talking, he quickly took out his mobile phone and took a photo of this huge skull.

It's just that when the phone's flash light was on, a human face suddenly appeared in front of him.

Before he could react, his whole body was dragged into the skull by a pair of big hands.

When he was grabbed by these big hands, his first reaction was that he was finished, and he met the legendary man in the center of the earth.

But just when he thought he was about to be stripped naked and put into the pot, a light source lit up in the dark space.

As the light came on, two familiar faces appeared in front of him.

"Mom and Dad!"

That's right, these two familiar faces are clearly his parents who haven't heard from each other for several months.

Yang Lin didn't expect that he could find them so quickly.

Of course, what was even more unexpected than him was the middle-aged man and woman standing opposite Yang Lin.
