The Julong still sailed to the extreme regions of Antarctica as scheduled, and the scientific expedition team left behind under the banner of finding minerals.Too many people are watching the movement of the giant dragon, so it cannot make any changes.In fact, military planes rushed to this island from the nearest cruiser last night...

"Still thinking about that?" Chang Mingyao saw Li Yu on the deck, walked over, and asked softly.

"No, in fact, there is no major interference. I think it is really amazing. At first I regretted participating in this scientific examination, but then I thought about it a lot. If I did not participate in this scientific examination, many Things, maybe I won't be able to see them in my life." Li Yu sighed.

He just finished talking with the confidentiality team this morning, when it was almost dawn, and the signing of various confidential documents made him want to cry.But the only thing that made him rejoice was that the unknown metal did not cause any substantial harm to them.After returning to the Giant Dragon, the cell examination did not reveal any abnormalities.His No. 7 fishing ground did not cause any special changes in his body.

Although Professor Xian didn't know what Li Yu and the others encountered, or what they discovered.Because Li Yu and the others all showed up at the assembly point according to the stipulated time.It didn't attract the attention of others. Last night, they circled around and secretly returned to the Dragon from the sea.

However, he could somewhat see the difference from the faces of Li Yu, Chang Mingyao, and Yang Jun, because he paid special attention to Li Yu, and he had also been exposed to similar things.So, I still comforted Li Yu a few words, telling him not to worry too much, not to have any burdens, and to do what he has to do.

Professor Xian would not say anything, let alone ask Li Yu what happened to them.Even if he asked about these things, Li Yu and the others dared not reveal the slightest bit.Even my own father couldn't say a word when asked.Li Yu heard that Professor Xian mentioned this kind of thing veiledly, and he has also been in contact with it. If he keeps the secret, it will not bring him any trouble, and he feels more at ease.After all, he never thought about telling the story, or using it for his own benefit.

Although the temperature of the sea water is already extremely low and icebergs are appearing more and more frequently, the diving sampling activities are also becoming more frequent.In this sea area, there are more species unique to Antarctica, and it is worthwhile for them to travel thousands of miles to study the creatures in this area.

Tonight, just the night when the time is right, they will reach the island belt of West Antarctica, and the first destination of the Dragon has also arrived-the Great Wall Station of Antarctica.This is also the first scientific research station established by our country in Antarctica, although it is not built on glaciers, but on islands.

This is the West Antarctic, which is the closest distance to the coast of our country, and it is only relatively speaking.But it was 85, and with our country's technology at that time, it was most appropriate to build a scientific research station here.Moreover, the activities of penguins, birds, and whales nearby are frequent, so it is also a protected area for these creatures.

And as the Julong advanced, Li Yu and the others also approached the Antarctic Circle.The Antarctic Circle is now in the polar day phenomenon, which means that within 180 days of the polar day, there will be no night in the Antarctic Circle!And the Arctic Circle, which is far away from it, is now in a state of polar night, and there is only endless night.

The Great Wall Station is on the edge of the Antarctic Circle, and has also been affected by the extreme daylight. Now there is only daytime and no nighttime.So the night here is just a concept of time.

When getting off the boat, Li Yu checked the time on the boat again and again. Could it be that the north and south poles are magnetically different, causing it to go wrong?It was eleven twenty-three in the evening, but it was as bright as day outside.Although the trainer had mentioned this question repeatedly during the training, Li Yu was still very surprised when he saw it.

Although it is the earliest research station built in Antarctica in my country, the environment here is not bad at all due to repeated renovations and expansions.Li Yu and the others will stay here for five days, and they will also explore and dive around here.Although this is only the peripheral area of ​​the Antarctic Circle, it is not within the scope of the Antarctic Circle in a strict sense.However, the temperature is already extremely low, with an average of more than thirty degrees below zero.Still in extreme daylight conditions.

It is more than 7000 kilometers away from Beijing. It is really called coming here without hesitation.And Li Yu and the others were not disappointed. When they disembarked, they saw many seabirds flying overhead.The birds that can survive in such an environment are definitely not cute and gentle, they are all tough.

Those birds glide on the surface of the sea, and as soon as they find their prey, they immediately catch it from the sea.Their sharp claws firmly hold the fish and shrimp, some small fish and shrimp, they hold them directly with their mouths.Li Yu saw a seabird with black spots on the top of its head and snow-white feathers.

Perhaps the scientific research personnel at the Great Wall Station have always lived in peace with these birds, so they are not afraid of humans.Li Yu saw the seabird dive into the sea from less than two meters away from him.The spread wings were almost one meter long, and the speed was extremely fast. When it touched the sea surface, the sharp claws grabbed an Antarctic cod from the sea.The cod was at least [-] centimeters long, but it was caught by the seabird's sharp claws, and it couldn't break free.

"Amazing!" Li Yu said involuntarily.

"That's an Antarctic tern. You can see that its tail looks like a swallow, and its body looks like a seagull. It is already considered a relatively docile seabird living on the island. But if you go out alone, don't get close to them. These terns like to attack humans, and if they see one traveling alone, they like to attack." Professor Xian said to Li Yu.

"Is this still docile?" Li Yu looked at the seabirds flying by in the sky from time to time, feeling a little scared.If this is called gentleness, how cruel is the seabird he saw just now with its wings spread like a cloud?

"Let's go, if you don't act alone, you won't be attacked by these seabirds." Professor Xian smiled, Li Yu was quite stupid in general.That's right, even Professor Xian had to admit that Li Yu had a "stupid" expression on his face.

But here, under normal circumstances, they really dare not act alone, and there are often death storms raging here.Antarctica is already considered a plateau region, with an average land elevation of more than 2000 meters.There are often strong winds, and because of this, Antarctica is the only one of the seven continental plates that is not inhabited.

Even the United Nations has a ban on dogs in Antarctica, which does not allow dogs to live in Antarctica.There used to be a canid in Antarctica, the Antarctic snow wolf, but it is also extinct and is the only extinct canid.This shows how harsh the climate here is.

Many people were frozen to death in Antarctica due to sudden changes in the weather in Antarctica and encountering hurricanes.There used to be a tourist plane full of 250 people who encountered bad weather in Antarctica. The plane crashed into a hillside and no one survived on board.

After entering the Great Wall Station, the indoor temperature is very comfortable. It is completely unimaginable that the difference between this wall is simply worlds apart.The Xuelong also brought food to the scientific research personnel stationed at the Great Wall Station this time, mainly green vegetables and fruits, which are in short supply here.

Of course, you don't have time to sit here and have a tea party or something.The experts went to their own groups to summarize the samples collected on the way.Then communicate with the people stationed at the Antarctic Great Wall Research Station. Li Yu and the others also need the scientific personnel here to provide the latest weather data so that they can go to sea for specimen collection.

After simple adjustments and rest, although there is no night, everyone's work and rest still follow the time. Li Yu and his diving team only start working in the morning when the time is right.However, the members of the diving team are still divided into two groups. There is a team that dives, and a pair that goes out in a small boat and collects specimens with ground cages.As a fisherman, Li Yu was naturally assigned to the group that rowed boats and used ground cages.

There are at least 200 kinds of fish living in this cold water, and the products are very rich.There were three people on Li Yu's small boat, and the other two were guards.Seeing Li Yu's familiar way of releasing the cage and harvesting the fish, the two of them immediately had a sense of seeing the fisherman.

"The movements are quite skilled!" Cheng Bing, one of the soldiers, said.

"I am a fisherman." Li Yu felt very proud.

Maybe it really is because the nets are lowered more times, even in the Antarctic waters, Li Yu can tell where fish like to gather.Regardless of the fact that these fish live under the Antarctic waters, you think that they are born to like low temperature and extreme cold.In fact, most fish still like places with higher water temperature, but they are forced to make a living.

Therefore, Li Yu will find some places with ice floating in the ground cages, and often more fish can be caught in these places.And there are floating ice blocks, which can provide a place of refuge for these fish, making it difficult for seabirds who are constantly patrolling in the sky to find them.

In addition to the most common Antarctic cod and krill, Li Yu also salvaged Antarctic icefish, which has a crocodile-like head.The mouth is also long, but it is characterized by the lack of hemoglobin, so their blood is only light pink.The whole body is covered with a transparent film, and some parts are as white as snow, showing a translucent appearance.

Their bodies and tails are small and short, and their heads account for almost half of their bodies.This kind of ice fish generally likes to live in deep sea areas, Li Yu went down to the ground cage and caught them by chance.

Cheng Bing and another soldier, Qian Hao, were amazed at Li Yu's continuous catch of fish.Their group has overfulfilled the task today, and it was done with ease.But when Li Yu caught a crocodile-headed ice fish, Cheng Bing and Qian Hao were really convinced!

All crocodile fish lack hemoglobin, but the crocodile ice fish is the only vertebrate that has no hemoglobin at all.Their blood is all white, and their whole bodies are close to snow white, even translucent.But they also have a little pink heart, which is a little cute.

They did not evolve to adapt to the environment and become what they are now. According to scientists, they are caused by accidental genetic mutations.This kind of mutation has greatly threatened their survival, and it is a bit pitiful to think about it...

Although Li Yu and the others harvested quite a lot and even caught the crocodile-headed ice fish, the three of them still insisted on completing the mission time.On the way back, Li Yu also met Captain Mu and his diving team who came ashore.

"Li Yu, come here, let me show you something rare!" Captain Mu waved.Their diving team also wears diving suits, which are specially made and have excellent thermal insulation effects.

Li Yule walked over, in fact, he also wanted to dive in the sea, but they didn't let him go.After what happened on the small island, he didn't want to take the initiative to ask Ying to do anything again.

Captain Mu turned on the camera and showed him a few photos, which were taken underwater, and there was a large piece of something that looked like ice and cotton wool.There was also an icicle that seemed to be washed down from the surface of the water.And at the section where the icicle is next to the bottom of the sea, a sea bird that keeps diving is freezing in the middle of the icicle.

This is a very famous death icicle in Antarctica. It is said that because the sea water suddenly cools down, after the salt is precipitated, it will suddenly freeze.As we all know, salt can melt snow. When some urban roads and rail transit are frozen and cannot drive vehicles, industrial salt will be sprinkled to help melt the ice.And the seawater is not easy to freeze because of the salt content, otherwise, it is estimated that the entire ocean in Antarctica would be frozen into ice.

However, the death icicle captured by Captain Mu is very special, as the seabird can be clearly seen inside.Perhaps, it was this seabird that encountered a sudden change in the weather the moment it swooped down to catch fish, and then it stayed under the sea forever.However, these death icicles will still melt, but this seabird has lost its life.

It's like when a scientist once went out from the research station during his scientific research in Antarctica. The weather was still sunny when a hurricane suddenly occurred and swept him away.And the cold took his life, and when others found him, his facial expressions showed how suddenly everything happened, so suddenly that he didn't even have time to show panic on his face.
