The cave is more than two meters high enough for people to move freely.

Bi Fang held the torch in his hand, carefully avoiding the huge cobwebs that spread out, and his eyes were amazed.

The firelight stimulated the giant spider that had been living in the darkness for a long time, and its limbs pulled white silk and hid towards the corners of the wall.

"I didn't expect to meet a Comacchi spider here, it's really strange."

The audience was inevitably surprised to hear this, and they couldn't help but think of the scene of the discovery of strange fish in the desert in the underground river.

Both are caves, and they have a strong sense of déjà vu.

Could it be that Comacchi spiders are also rare?

Bi Fang nodded: "This spider was accidentally discovered by researchers when they were examining specimens in the museum, and then registered. ”

"In order to find the living body, the scientific investigation team went to South Africa to carry out several scientific expeditions, but found nothing, so much so that people worried that the Comaci spider was extinct."

"It wasn't until later that an investigator in South Africa stumbled upon a male and two female Comache spiders in a park, confirming that the Comache spiders were still alive."

It is not uncommon for specimens to be recorded first, and then to be recorded.

Before the systematic development of biological science, adventurers had already left their footprints all over the world.

When they come across a rare and exotic creature, they will capture it and make it into a specimen, which they will consider as the glory and talk of their adventures.

As for what kind of species this creature is and what role it has, everyone does not care.

Those who listen to the story see it only as a medal of courage.

Huge beetles, insect-eating plants, blood-red corals, these are all curiosities.

In the same way, spiders that can weave a large web that is rare in the world cannot be spared.

When adventurers die of old age or die unexpectedly, many specimens may be lost, or they may be treasured by future generations, or they may be donated or sold to museums.

One day a hundred years later, after a careful recorder sorts it out, it is possible that the specimens buried in the corners of the museum will be rediscovered.

It's just that in a few hundred years, some of the original species of specimens may have long been extinct, and no living organisms can be found anymore.

"I don't know exactly how many Comache spiders are left in the wild, but it's certain that there won't be a lot of them."

Bi Fang said in a brisk tone, "So it's a lucky thing to see it here, and we're lucky." ”

In a normally abandoned diamond pit, the probability of picking up a leak is very small.

There are really small, high-purity broken diamonds, even if the mine owner doesn't like it, the miners who withdraw in the end will not let it go.

Unless this is not a normal abandoned mine, or if you are lucky enough to dig a rock wall, revealing a long-undiscovered diamond of considerable clarity.

Therefore, Bi Fang came in without the idea of being able to get something valuable, but more to satisfy the curiosity of himself and the audience.

Now you can see the rare Comache spider, which is completely unexpected, and it is already a worthwhile "drill".

"Let's go, let's move on."

Bi Fang avoided the cobwebs and headed deeper into the mine.

The darkness deepened, and instead of getting smaller, the cavern became more and more empty.

This made the audience's heart even more depressed, and Bi Fang's movements became more and more careful.

"If you usually go on wild adventures or are killed, and you encounter a large number of spiders in the cave, you must be careful, not because the spiders are poisonous, but because there are a large number of spiders living in the cave, which provides the possibility of higher organisms in the food chain."

What is the possibility of higher organisms?

Many viewers were puzzled.

"It's very simple, first, there are a large number of spiders in the cave, which proves that it has been abandoned for a long time, and animals have long occupied the cave."

"The second is that spiders will also become a member of the food chain, it is not the top, many venomous snakes like to eat arthropods, caves are their favorite environment, even more so with food, larger and more poisonous snakes are deadly things."

"As for spiders, they're nothing."

Bi Fang held the torch and moved at a slow pace, cautious and cautious.

At the same time, there was some knowledge exchange with the audience.

"It's not what everyone thinks, spiders are very little of a threat to people."

"On the one hand, the vast majority of spiders are very vigilant and will avoid contact with humans, and will warn before attacking when they are forced to do so."

"For example, the Australasian funnel web spider will first lift the front two or four feet up as a warning, and you should stay away when you see such a movement."

"So far, scientists have not found any examples of spiders actively attacking humans, including the common spider species in our lives, such as jumping spiders, house ghost spiders, large wood forest spiders, and so on."

"On the other hand, most of the spiders are not venomous, and even if they do, they are too small, so small that even if you are bitten by a highly venomous spider, they can basically heal themselves."

"At present, we have only found that the venom of 7 species of spiders can cause harm to humans, among which the venom of the Australian funnel web spider can directly cause human death, but as long as the antivenom is injected within 15 minutes, it can be out of danger."

"The venom of the remaining six species of spiders is currently not thought to directly cause human death."

"For example, the famous poisonous spider Black Widow is one of the six remaining species, which is 15 times more poisonous than rattlesnakes, but because it is too small, there is almost no fatal danger."

"About 2,200 people are bitten by black widows every year in the country, but there has not been a single authoritative death report so far, and its venom can cause muscle pain, abdominal cramps and rapid heartbeat in humans at most, and the injured can be cured without medical attention, unless you happen to have cardiovascular and cerebrovascular diseases."

"Also, spiders rarely inject all the venom at once."

The spider can accurately control the amount of poison released, whether it is attacking or counterattacking, it will not use up all the venom at once.

Venom is a spider's weapon to capture food, and it needs to be used wisely.

Larger crickets are more poisonous, smaller flies are less poisonous, and each meal has a planned amount of venom.

If you run out of venom all at once, it will take a few weeks to replenish the venom.

This means that spiders without venom weapons may starve for weeks.

Even if you pinch the spider's belly, it won't release all its venom to attack you at once.

"You are not food for a spider, and it is reluctant to waste its precious and limited venom on you."

"The amount is small, the injection is small, and there is only one outcome."

"Venom is not a virus, there is no way to reproduce itself, the amount will not increase, injecting venom into the human body is like dripping cyanide into the sea, you can't poison anyone."

"Of course, dripping into the sea is an exaggeration, but the meaning is about the same."

"Even in the last century, there were only 13 reported spider deaths."

[Sent, disliked]

[Bite you hard]

[, is this the case, I'm shocked]

[The fear of spiders is much smaller all of a sudden]

Along the way, Bi Fang didn't make any special discoveries, except that he saw some symbols on the walls, perhaps used by miners to communicate with each other or graffiti casually.

It wasn't until about thirty or forty meters later that the corridor suddenly widened, the height did not change much, but the width suddenly reached nearly ten meters.

At the same time, three openings in different directions appeared in front of him.
