On the deck, a group of people stood, all dressed in thick coats and wrapped like penguins.

If it was a normal day, it was not yet dawn and everyone was still sleeping, but now there are a lot of people here.

Obviously, everyone is here to get up and see the aurora.

Huge cruise ships are complacent with ice floes flowing over the ocean, shattering pieces of thin ice and leaving a clear trail of water.

The Arctic Ocean is an ocean covered by sea ice, with perennial water accounting for about two-thirds of the ocean's area, and the rest of the ocean also has a large number of ice floes and icebergs.

About half of the sea freezes all year round, and the rest melts in the spring and freezes in the winter.

The sea ice in the center has been around for 3 million years, making it permanent.

The climate type is even more singular, and it can be summed up simply in one word, cold.

"Whew, it's cold."

"It's too cold, how many degrees is it now?"

"minus thirty."

"Only thirty? How do I feel colder than yesterday? ”

People who ask about the temperature are wondering, it was thirty a few days ago, and it is even colder today, why is it still thirty?

"That guy is an ugly countryman, he's talking Fahrenheit, it's close to minus 35 degrees Celsius, hell, my nose is going to freeze off, and Steven will laugh at me when I go back."

"Damn, my thermometer won't move!"

"Huh?"

On the deck, a man tapped his thermometer against the railing, making a metallic crashing sound.

The temperature on the thermometer did not move at all, which made the man a little angry.

"The freezing point of kerosene is minus 30 °C, it is frozen, of course it cannot move."

The sound came from the direction of the cabin, and everyone looked up, just in time to see Bi Fang closing the door and walking to the deck.

"Yo, it's Mr. Bi."

"Did Mr. Bi get up to see the aurora too?"

"Do you have any stories to tell us today?"

"I watched the video last night, it's amazing, I regret not knowing each other earlier."

Everyone greeted each other, and within a week of getting along, everyone on the ship knew the young man, from the captain to the cook to the tourists.

Bi Fang smiled and nodded, came to the man who shouted that the thermometer was broken, and leaned on the railing: "Generally speaking, there are three kinds of thermometers, kerosene, mercury, and alcohol. ”

"The freezing point of kerosene is only minus 30, below this temperature, it will solidify, and it will naturally not move, or the cold shrinkage effect is very small, almost invisible to the naked eye, and the freezing point of mercury is minus 38.87 °C, which cannot be used."

"You can only bring an alcohol thermometer to the North Pole, because only its freezing point is minus 117 °C, which adapts to all the low-temperature natural environments on the earth, and fortunately you don't use mercury, otherwise it will be very dangerous in case of an explosion, but the thermometer generally rarely uses mercury."

There are many differences between thermometers, the most common being a thermometer and a thermometer.

A thermometer is usually mercury, while a thermometer is kerosene and alcohol, both of which measure something that can be understood literally.

"Why?"

Someone shouted in the back.

Bi Fang raised his head: "Because the mercury expands slowly when heated, it will not cool down quickly after being taken out of the body, and it needs to be shaken off to return to zero, and it is relatively simple and intuitive to use it to measure the temperature, and it can also avoid the error caused by external temperature transfer." ”

"Kerosene and alcohol thermometers, the expansion of heating is very obvious, the change is very rapid, a cold and a hot will rise and fall quickly, so it is generally not used to measure body temperature, will be made red and hung indoors, used to roughly monitor the weather temperature."

Everyone suddenly realized.

"Are you all up so early today?" Bi Fang looked at the time, and breakfast hadn't arrived yet.

Although the real polar night has not yet arrived, the unusually short day is a reminder to pay attention to the time.

It may be that the vast majority of people will not have the experience and experience of the polar night, but it is conceivable that the polar night is not easy to spend and there are many problems, such as the disorder of people's biological clock.

A large part of the human biological clock is dependent on natural light.

Therefore, a very important way to regulate the rhythm is to eat, and the opening time of the ship is fixed, and only three meals are free.

I want to add food, sorry, I have to add money.

"It's all here to see the aurora."

"It's beautiful."

"yes, it's almost dawn, can you still see it?"

"It's also available during the day, of course."

"Mr. Bi also got up early."

"Hmm." Bi Fang nodded, pointing to the ice floe not far away, "I'll get off the boat when I find a good place when it's dawn." ”

It's time to disembark!

Everyone was a little surprised, but not too surprised, everyone knew that the purpose of Bi Fang's trip this time was to come to the northernmost point of Greenland.

I just didn't expect it to come so quickly.

Half an hour later, the green belt in the sky was still there, and a second natural light slowly appeared from the sky, and the dark black curtain was lifted, and the fish belly was white.

A century ago, on the other side of the globe, on the Antarctic continent, some of the world's bravest men embarked on a life-or-death adventure.

On the left is the flames, on the right is the sea, and in front of you are the dreams and glory that the heart has been striving for.

A century later, a young man arrives at another node on Earth, carrying no supplies and will be here to survive for a hundred days.

The cold wind howled.

The 70-metre-proof ship smashed into a piece of ice floe once more, and the sun hung obliquely from the bow of the ship.

The bow of the ship seemed to have smashed into the most dazzling giant sun, leaving behind a scattered white light that spread in all directions.

The shivering tourists squinted and raised their heads, and in front of them was a white expanse, not a piece of white ice floe, but a continent, a vast and pure white continent.

No trees, no grass, no living things.

There was only an endless cold wind, like a steel knife cutting through the face, there was no blood, and all the blood was frozen into blood-colored ice edges at the moment it was about to splash out.

Many viewers couldn't help but touch their faces, the skin on their faces was almost unconscious, until their warm fingers touched the skin that seemed to have turned into ice cubes, and they didn't know that their faces were not cut by ice blades, and everything just now was just their own delusion.

The familiar sound mixed with the sound of the wind sounded in their ears, and everyone heard the sound, and at some point, the drone that seemed to never be damaged had been hung overhead.

"Looking back at the process of human transmutation and evolution, if our ancestors had not taken risks and imaginations, and had not had the broad-mindedness and magnificent feelings of courage to innovate and sacrifice, human beings would not have used canoes to surf the sea and explore the infinite mysteries on the other side of the ocean."

"Human curiosity produces the urge to take risks, and human adventures have lit the torch of civilization."

"Adventure is not only in the natural seas and mountains, between the desert and the swamps, but also in the densely populated cities."

"I'm Bi Fang, a professional outdoor explorer, and this time, we're in the North Pole."

The Whanganui River, which flows through New Zealand, is considered a living creature and even has certain rights. Maori tribes believe that this is their ancestor, so harming a reservoir is tantamount to violating the rights of the tribal people. Now there are two guardians in the river: one Māori and the other Kiwi.
