"Actually, some people say that the red-haired prototype in One Piece is the red-haired Eric. I don't know that. It's anecdotal, everyone just listens to it."

Bi Fang took a breath.

Walking on the ice field is too tiring. For safety, he can't walk too fast, otherwise the possibility of falling will be greatly increased.

And standing on the unobstructed ice field, you can clearly feel that the body's heat is being taken away, even if the amount of exercise is not large at all, the physical exertion is not small at all.

"In polar regions, it's important to cover your body to protect against cold temperatures and strong winds, especially your head and feet, and don't stop."

"We have energy reserves in our body, that is fat, and by consuming fat, we can also generate calorie value, so I have been eating high-calorie foods these days, drinking milk tea as water, donuts as meals, and cheese as seasoning, just to Gain weight."

Hiss, I said, I vaguely feel that Lao Fang has gained a lot of weight]

Good guy, this guy... eat a meal to gain ten pounds]

Bi Fang breathed a sigh of relief, but there was no warmth on his face at all.

The sun's irradiation has made the temperature rise a lot. It is about minus thirty-five, but it is still very cold. The huge temperature difference is like a giant pump, which empties all the heat and has a lot of horsepower.

"The best way is to keep walking, which can ensure blood circulation in the body, and also avoid excessive exercise that leads to sweating."

"If you start to sweat, you must loosen your clothes and ventilate in time. If you get wet with sweat, it will reduce the warmth retention effect. At the same time, pay attention to keeping the clothes clean. Sand and grease will block the gaps in the clothes and reduce the effect of isolating cold air. ."

After walking for nearly four hours, the surrounding area is still empty.

Bi Fang stopped in place, and he looked around. At this time, the sun had reached the highest point, but it was still very low, as if it couldn't rise, making people feel that 30 degrees would be enough to pass normally.

"I can't go any further. The icefield is bigger than I thought. It may be more than two days, maybe three days. Taking advantage of the high temperature now, we have to stop and prepare for the night."

The width of the ice sheet is wider than Bi Fang imagined. Every summer, when the sea ice melts, it starts to freeze in autumn. It seems that this year's sea ice freezes very fast, and this winter may be colder.

"The weather is actually very good today. You see, the air visibility is very high." Bi Fang pointed to the surroundings.

Indeed, the air here is terribly clean, except as cold as a knife, the sea ice is boundless as far as the eye can see, and the spread is all blue and pure white, as well as warm yellow sunlight.

The world is very elegant.

"If you are forced, such as a plane crash, or other reasons to get to where I am now, then this is the best time to call for help. The skills in this area are similar to rescue in the mountains."

"Bright colors and linear shapes are easier to spot from the air. Even a piece of black clothing can be seen from far away on barren snow."

"Burning animal fat produces smoke. You can also use ashes and burnt debris to mark snow and ice, so don't skimp on your expensive calfskin belt."

"Search and rescue flights can only be done in certain weather conditions, so you need to be prepared. Helicopters are unlikely to come to your rescue in a blizzard unless you also have a Fortune 500 company on your team. daughter of the family."

Bi Fang made a joke, and I still remember the second live broadcast that someone questioned the unreasonable speed of the rescue. It was a director's play.

In fact, it can only be said that these people do not understand wilderness and human power.

"Most of the snow rescues may be aircraft with sleds, which are not very skilled in the world, so you need to find a place as a runway for landing. This place does not have to be very flat, but there must be no Obvious things that could damage the aircraft."

"Large, hard, undulating snow formed by the wind, commonly referred to as 'snow crests', cannot be landed. A flat surface, about 100 meters long and covered with a thin layer of snow, is ideal for landing. , this kind of place would also be a good place for us to stay, because then we can spot the approaching polar bears at a glance.”

Bi Fang squatted down, started slicing ice with a knife, and said.

"Contrary to what many people think, the polar bear's hair is actually not white, and the skin is even black. The reason why it looks white is because it has two layers of hair, the outer layer is about 515 cm long It's made up of protein, with a hollow in the middle instead of a solid."

"This peculiar structure, while receiving sunlight, can hide the sunlight in the hollow hair, and then refract it at a certain angle. At this time, the polar bear's hair will look pure white, and it is very difficult to hide in the snow. It was found that it was almost exactly the same as the surrounding environment."

Therefore, a flat and open environment around it is very necessary, and the existence of the behemoth can be seen at a glance. UU Reading www.uukanshu.com

"The reason for this is that this hollow wool is waterproof and heat-insulating, which is equivalent to the onion dressing method we use, which can not only meet the needs of mimicry, but also keep warm."

Bi Fang also mentioned the onion dressing method before, that is, compared with thick clothes, the same thickness of multiple thin clothes will be more thermally insulated, and a thin air layer is formed between the clothes and the clothes, which plays a role in preventing the loss of heat. Effect.

And it is also easy to put on and take off, so as to achieve the effect of use in different environments.

For example, Bi Fang is going to build a shelter next. The amount of exercise is slightly higher, and he can take off one layer to avoid sweating.

As Bi Fang advanced, the snow on the ground had begun to accumulate, which was good news, indicating that he was approaching land.

"I've always said before that one of the keys to survival is knowing where you are. As long as you know where you are, you can be prepared for many things."

"Greenland's high latitude, high average altitude, and glacier coverage have resulted in a perennial cold high pressure on Greenland. Due to the cold high pressure, the temperature in Greenland is low, and there are many cold currents around Greenland. It also promotes its cooling effect.”

"But do you still remember Svalbard, the temperature is very warm even though the latitude is higher, because the warm and humid Atlantic air flow is very strong, which will bring abundant precipitation to the coast. In winter, the warm and humid Atlantic air flow reaches its peak and is very strong. ."

"When the two collide, it is the most common cold and warm front system in geography textbooks. It's just that it doesn't rain, it snows, so Greenland has more blizzard days."

"But Greenland itself is surrounded by cold currents, and due to the terrain, it cannot drive straight in. It will only snow on the edge of autumn and winter to supplement the ice cover to a certain extent. At this time, the sea surface just begins to freeze and continues to spread to the outside."
