For such a long time, it is not only Shen Nan and Bai Han who have progressed.

From being at a loss at the beginning, to now not forgetting to join the interaction in the process of science popularization every time, Wen Wanwan has also become a qualified anchor.

As the question was thrown, the audience in the live broadcast room also had a heated discussion.

The evolution of animals is based on the environment, and those who cannot adapt to the environment die in the changes again and again, and those who can survive are those who can adapt to the environment.

The polar bear's hollow transparent fur, combined with its black skin, must have something to do with the environment.

Looking at the possibilities put forward by the audience in the live broadcast room, Wen Wanwan also explained to them with a smile.

"At the moment, the first theory is that structures like polar bear fur reflect sunlight onto the black skin underneath the fur, helping to absorb more heat."

"Another way of saying this is that this structure is designed to evaporate water more quickly, so as not to take away the heat from the body."

"In addition, the thick layer of fat under the polar bear's skin further insulates the cold from the body."

"It's okay in winter, but if it's a daytime temperature like this, they'll have to lie on top of the ice to cool down."

Speaking of this, Wen Wanwan paused for a moment, and then took the camera to the audience in the live broadcast room to zoom in and take a look at the special hollow hair of polar bears.

"In 2005, Chicago was experiencing a scorching heat, alternating between humidity and hot and dry, which caused a lot of algae to grow wildly."

"And the polar bears that live in the Brookfield Zoo have hollow hair, so much so that they are also multiplied by algae, and their whole bodies turn green."

The Chinese alligator is beaten every day: [Hiss, green polar bear? 】

I walked the dog and pulled the ball: [Although it seems strange, I always want to see what the situation is!] 】

Be a cat: [Green, hahaha, forgive me for this shi-like joke!] 】

At the same time of popularizing science, Su Xiu and Ouyang Zhi on the other side also took out the leg of mutton and put it in front of the polar bear.

As a big bear who is a mother, the leg of mutton is suddenly reduced by one-fifth.

The strong bite force can even bite the bones directly, and the creaking sound makes Ouyang Zhi, who was feeding, silently take a few steps back.

He didn't think that his bones could be much harder than sheep bones, this guy could easily bite the leg bones, and at most he could stuff his teeth because of years of exercise.

But this is probably the biggest difference between men and women, one thinks rationally, and the other is always emotional.

Su Xiu didn't mean to be scared at all, but looked at the polar bear who was taking a big bite of dry rice and smiled at her aunt.

Many pet owners should have this habit and like to watch their children eat in a big gulp.

Every bite you take can bring you great satisfaction.

A leg of mutton was completely wiped out in just a few minutes, and the female bear, who had not eaten for a long time, patted her belly comfortably.

For humans, it may take three or four people to eat this leg of lamb, but for polar bears, it is at most a bowl of rice, and it is far from being full.

Polar bears, who have always been adults, eat at least 20 kilograms of food a day in order to satisfy their daily activities.

For example, a mother bear with her cubs has to eat two or three meals a day, adding up to 40 kilograms to be considered full.

"I'll go back and find a big block of ice, drill a hole and drag it along."

Wen Wanwan hugged the two little guys, thought about the size of the snowmobile, and quickly arranged the next task.

Unless the four of them are willing to run behind the car, if they want to take one big and two small with them, they can only choose to drag.

Wen Wanwan gave the little guy in her arms to Su Xiu, and then touched the head of the female bear and rushed towards the snowmobile parking spot.

rushed all the way to the vicinity of the big pit, Wen Wanwan found the chain saw from the motorcycle, assembled it, and handed it to Ouyang Zhi.

"With a thickness of about fifteen centimeters, a square of two meters should be about the same."

Ouyang Zhi took the chainsaw and nodded, his eyes quickly patrolling around.

The ice in the Arctic is very different from the ice that we come into contact with in our daily lives.

The ice here is often found in temperatures of minus thirty or forty degrees, and its hardness and density are many times higher than that of ice machines.

As long as it's the right size, you can use the ice here as a trailer to pull a polar bear through the snow.

After more than half an hour, a barely usable ice car was made.

After attaching the rope to the snowmobile, Wen watched as the polar bear groped its chin.

"Can you catch it, no, I'll tie it up for you?"

"Hmm~~ I can!"

The she-bear tentatively hooked the ice cube with her paws, making sure she could lock it securely.

Seeing that it was indeed no problem, Wen Wanwan was also a lot relieved, and sat in the back seat with the cub in her arms.

As Ouyang Zhi started the car, the four people and three bears also rushed back towards the temporary base.

"Stationmaster, did the animals we collected go by sea?"

"Take the land transportation and go through the woolly bear country to Mohe."

Compared to the time it takes to travel by sea, there is no doubt that land transportation is faster.

Taking advantage of the time to hurry, Wen Wanwan also introduced Mohe, the northernmost city in the Shenzhou Continent, to the audience in the live broadcast room.

"If you want to see the snow in winter, there is actually a very suitable place in Mohe."

"The Mohe River is originally a river, also known as the Mo River, which originates at the northern foot of the Daxing'an Mountains and flows into the Heilongjiang River."

"In that city, there was originally a village called Mohe Village, which was originally just an ordinary small village with more than a dozen families living here."

"Later, for the sake of tourism, after many discussions, the village was renamed Arctic Village."

"Every year from June to August, you can go here for a while and you will have a chance to see the Northern Lights."

"From October to February, the temperature drops to minus 30 to 40 degrees Celsius, covered in knee-thick snow."

"The unique culture of the Northeast, coupled with the scenery of the icy and snowy land, attracts countless tourists."

"Here, you can find a word for the most casual thing."

"The northernmost post office, the northernmost restaurant, the northernmost hotel......

"Who wouldn't want to pull once in the northernmost toilet in the country?"

With Wen Wanwan's introduction, the audience in the live broadcast room also began to be full of curiosity about this village.

Arctic Village is a complete tourist attraction, and everything here is for the tourists.

Eating a hot copper hot pot in knee-high snow can be said to be full of enjoyment.
