Reindeer, old friend.

These big guys all have horns and a lot of them, and they are gathered together at this moment, and they look quite spectacular.

On the snow, Bi Fang and six dogs were buried in the snow, and seven pairs of big eyes were dripping, as if they saw hundreds of huge barbecued meat with bones running on the endless snowfield.

The dog barked softly, and pulled the corner of Bi Fang's clothes with his paws, as if he wanted him to hurry up.

Bi Fang didn't show too much excitement, knocked the dog's brain, touched his chin and thought: "There is no cover, it's a bit troublesome." ”

As soon as the words fell, the drone rose high into the air, showing all the landforms within a radius of hundreds of meters, all of which were snowfields, unusually flat, and there was no suitable cover to cover the figure.

Such a landform, let alone close to twenty meters, even fifty meters will be easily discovered.

It's just that the method is finally figured out by people, Bi Fang quietly unfolded the musk cowhide and splashed dry snow on it, although occasionally a little black hair can be exposed, but on the surface, it can already be integrated with the environment, not so eye-catching.

Bi Fang lifted the corner of the musk ox hide, drilled inside, and slowly approached the reindeer herd with the musk ox hide.

Musk leather is a really useful thing, you can sleep at night, and you can use it as a cover during the day.

"It's not the first time we've encountered reindeer, but I'd like to say that this time we may not have encountered the same two times as before."

Crawling forward on his stomach consumes a lot of physical strength, and it is also very cold to rub against the snow at close range.

Instances of herbivores being preyed upon by predators can be said to happen at any time, and usually, when herbivores encounter predators, they will only choose to flee quickly.

But for some herbivores, escape is not the only option, as was the case with the musk oxen that Bi Fang encountered in the Arctic.

"Reindeer are social animals, they usually have 6 to 13 in a 'family group', and several 'family groups' form a large group, usually in the hundreds, so that they can form a unique formation to defend against the enemy under the right conditions."

Formation?

This word, which has the flavor of ancient art of war, makes sailors look at each other.

Deer do the same?

Bi Fang nodded, affirming the audience's guess.

"The formation of the reindeer is called the whirlwind formation, which is named because it is similar to the whirlwind, but this formation is not complicated, that is, the entire reindeer herd revolves around a common center, after all, it is just an animal, more of a succumb to instinct, but it is quite strong for predators in nature, after the formation is activated, let alone a wolf, even a tiger can do nothing."

"Carnivores hunt prey in groups and generally only attack some of the weaker individuals, but in a reindeer whirlwind, the weaker ones in the group are located in the center of the formation, which makes it impossible for predators to target their ideal prey."

"In order from inside to outside, the speed of the reindeer whirlwind is gradually increasing, and the further out the reindeer are, the faster the reindeer, and the ones located in the outer area of the reindeer whirlwind are almost all the strongest in the group!"

As a large hoofed animal, a strong reindeer can even weigh more than 200 kilograms, and some particularly strong individuals can even exceed 300 kilograms.

In addition, adult reindeer have long, branched horns, which constitute a powerful attack power of reindeer.

"After the reindeer formation is activated, the reindeer on the periphery will start to run at high speed, and if the predators rush into the formation at this time, then they will be constantly hit and trampled by the strong reindeer that come one after another, and they are likely to be pierced by the antlers during the process, so many predators are powerless about it."

After resting, Bi Fang draped the musk oxhide over his head and continued to crawl forward.

It's just that the fundamental reason why humans behave completely differently from other creatures is that they are good at thinking, and soon some people raised the bug in this formation.

[If it's a whirlwind, it shouldn't be easy to move, so when it's tired and has no strength, wouldn't it be a neck to be killed? 】

[Yes, if you are tired of running, you will stop]

Seeing the barrage, Bi Fang stopped again, blinked, and said with a smile: "You are completely right, so when humans come, the reindeer will become extinct." ”

The audience was dumbfounded.

[Co-authoring this thing is useless to humans? 】

[It's me]

"Human beings are actually an animal with a greater degree of isolation from nature, well, this is not easy to explain, simply put, in the process of evolution, we humans have not actually co-evolved with many creatures, so most of the resistance methods evolved by animals are not useful to us."

"Reindeer are good running animals, and the temperature in their living environment is very low, which is good for the heat dissipation of the body, so the reindeer cyclone can last for a long time, and carnivores in nature do not have the logical thinking ability like humans, they will only make judgments based on the situation in front of them, and will not wait too long."

"On the other hand, when a large number of reindeer are running together, a lot of splashes are excited on the ground, and there is a lot of vibration and noise. Obviously, this is also a big deterrent to predators, so they usually choose to leave when faced with a reindeer whirlwind. ”

Unfortunately, these two tricks are nothing to humans.

As long as you see through the essence of the reindeer whirlwind, humans will not be scared at all.

For humans, a strong formation in nature like the reindeer whirlwind is ineffective, especially in ancient times, and humans who have learned how to use tools to attack from a distance are invincible.

"The reindeer formation is powerful, but it is actually very stiff, it is just rushing in one direction, and the threat is not as strong as the musk ox's group counterattack, which is really dangerous."

The formation of musk oxen is to surround the weak group, after which the strong musk ox will confront the predator, counterattacking and onslaught, which is flexible and tricky.

Reindeer that only spin in circles are dangerous, but as long as you take precautions, they are nothing.

"Before catching reindeer, it was either on a frozen river or in a hill, and the terrain was not convenient for them to spread their formation, so they could only scatter and flee when they encountered danger, but now we are on an open ice field, so we need to pay attention."

Speaking of which, Bi Fang was already quite close to the reindeer, and he held the spear and waited for the opportunity to move.

At a certain opportune moment, Bi Fang, whose spirit had been raised to the limit, suddenly jumped out.

The reindeer woke up suddenly.

As Bi Fang said, all the reindeer formed a circle of self-help, layer by layer, and the strongest deer on the periphery ran quickly around the circle, and they rotated tightly along the "eye" in the center of the spiral shape, and the earth shook under the trampling of the deer's hooves.

Just like galaxies orbiting the center of the Milky Way, they are tropical cyclones rotating over the oceans.
