Bi Fang walked among the trees, took off his gloves, and touched one cold tree after another, and behind him was a hundred-meter-high cliff, which was a natural city wall.

Nature is so vast, but the landscape is quite brutal, there is not a trace of green in sight on the ground, and it is all covered by thick snow.

Standing in the forest located in the Arctic, as a human being, Bi Fang inevitably felt a little small.

Looking behind you, on the cliffs, a huge inland ice surface forms an ice tongue, which could fall from a high altitude under a storm at any moment, smashing everything to pieces.

In Greenland, there are endless wild places as far as the eye can see.

"The Arctic region, in all respects, is quite extreme, and only those species that can successfully adapt to the harsh climatic conditions here, with a huge difference between summer and winter, have no leaf litter, almost all the trees are green, and absorb as much sunlight as possible for photosynthesis."

Bi Fang rubbed the tree, leaving some scratching marks very clearly, he squatted down, shoveled the snow off the ground, and found a community of moss that had been gnawed.

The edges of these mosses have left tooth marks, and it is clear that herbivores have visited the area and left traces.

More snow was dug up, and soon, more marks were exposed, not only large footprints, but also some long brown hairs.

Looking at the hoof prints on the ground, the audience felt a little familiar.

[What is this?] Reindeer? 】

[It looks like it, but it feels like it's a lot bigger.] 】

Bi Fang dug out the remaining moss on the ground and shook his head: "It's not a reindeer, the reindeer don't have such a big size, these are the footprints left by the musk ox." ”

What kind of cow is musk ox? 】

[Blind guessing is a big cow]

【Can I eat it?】 】

"The musk ox is the representative animal of the Arctic tundra and the northernmost ungulate of the planet. Of the ungulates, none lives further north than the musk ox, not even the reindeer. ”

"It is said that the undercover shed by musk oxen during the annual shedding period is eight times warmer than that of sheep wool, and its external protective cow hair is also the longest in the animal kingdom, even up to 60 centimeters long, which perfectly resists the low temperature of minus 40 degrees."

Bi Fang gave a brief introduction, and then pointed to the very clear footprints on the ground.

"The reason why you think the footprints of the two look similar is because it and the reindeer are both artiodactyls, and both are ruminants, until the family is different, so the footprints look similar at first glance, but the difference in size between the two is huge."

"The musk ox generally weighs more than 300 kilograms, and the reindeer is less than half of it, and it is precisely because the musk ox is too large in size, and likes to flock in groups, there are almost no opponents, and they are very domineering when they walk, so they will often scratch the trees, on the contrary, the reindeer rarely appear in this situation."

[Hiss, three hundred kilograms? 】

[Damn, it's enough to catch one, right? 】

[Suddenly I feel that the twenty kilogram goal set by the old party is not so outrageous, this one is enough, right?] 】

【Cluster?】 My DNA is moving]

The soil here is all frozen soil, and it is difficult to disappear the marks left by one foot down, which makes it difficult for Bi Fang to judge the time when the prey will leave.

Bi Fang closed his eyes, his nose twitching slightly, trying to catch the residual scent of musk oxen in the air.

"The reason why musk oxen are called musk ox is because both female and male musk oxen emit a musk-like smell, especially in males during estrus."

"But the smell doesn't come from specialized glands, it's from their urine, hence the 'body odor' of musk oxen."

In the air, a faint smell quickly entered the nasal cavity along the air, but it was not obvious, and Bi Fang had to lie on the ground to distinguish it again.

[The taste is heavy]

[Damn, isn't that the smell of urine?] 】

【Musk-scented urine (dog head)】

[What's this, diluted a thousand times or jasmine]

[Ah, I know this, a certain chemistry teacher never gives his girlfriend jasmine perfume, and every time he sees someone else using jasmine perfume, he laughs and doesn't say anything (dog head)]

"This one is wrong."

Bi Fang opened his eyes and shook his head behind the barrage.

"The feces are diluted and still smell of feces, but they don't smell as much. Jasmine is still jasmine-scented when it's strong, but it doesn't smell so good. ”

"This statement comes from 'indole', which is indeed the odor component of feces and jasmine. Keane, a former Perfumer at Hermès, described the high concentration of indole smell as a corpse odor, which I thought was like the smell of cow poop in the countryside. ”

"But when the roar is diluted to 0.1% or less, it's not the full jasmine flavor, or even the main ingredient in the jasmine scent."

"Taking Jasmine Macroflora Pure Oil as an example, the odor components have a sweet fruity aroma, a soft sweetness, a dry tea smell, both grass and floral aroma, a refreshing floral fragrance, a hay flavor, and then indole, with a content of about 0.16%, and about 20 odor components."

【？？？ 】

[Is this something that people can smell?] 】

[Damn, this is real cowhide]

Bi Fang shrugged his shoulders, these are all smelled by professional perfumers, and he can't do it himself.

It takes a lot of training to distinguish smells, and it is not enough to have a good sense of smell, and a person who has never smelled jasmine will not know what it is when he suddenly smells it.

He has a strong sense of smell, and is more to help Bi Fang track and seek the enemy.

"The opposite is also true of feces, which is not entirely composed of indoles."

"If you are really a chemistry teacher, you should know that the smell of natural substances is inherently complex. It is normal for things that are far apart to have the same or similar odor composition, and cheese, beef, pork, shrimp, eggs, strawberries, cherries, peaches, and other foods also contain a small amount of indole. ”

"Can you admit that you actually ate it, forehead ......" Bi Fang scratched his cheek and smiled, "That?" ”

[, I was confused for a long time, and finally saw an authoritative explanation]

[Cowhide, the truth still depends on the old party]

[So it smells?] Is the musk ox still gone? 】

Bi Fang nodded and picked up the stick on the side.

"As I said, the musk ox has a stronger smell during estrus, and its breeding season is from mid-September to October every year, and after the summer of recuperation, the musk ox accumulates a lot of energy. Females are mainly used for reproduction, and males also compete for reproductive rights during the estrus period in autumn. ”

"At this time, the musk glands on the face of the male musk ox secrete a strong smelling secretion, which is touched by the legs to the plants on the ground, so as to carve out their territory, and the female musk ox is enclosed in it, strictly guarded and protected, and no other male musk ox is allowed to encroach on it."

"As a result, the smell on the ground is going to be stronger, and that's why we're lying on the ground just now."

"But ......"

Bi Fang raised his head and looked at the sky.

It's getting dark.
