Dense black dots appeared on the horizon like a screen window, and the whole thing looked like an ever-expanding cloud ball, expanding wildly and moving slowly, terrifying onlookers who didn't know why.

The style of painting is too weird.

Even Bi Fang observed and wondered, and only then popped out of his mouth a word that surprised everyone.

Locust!

Hearing this word, countless viewers have barrage.

[Locust, I heard you right, right? Is this thing a locust? 】

[Damn, are there still locusts?] I always thought this thing was extinct.]

[You live in the future century, why don't you have locusts]

[I don't think I've ever seen this thing before]

[I must have seen it, but I may have mistaken the locust as a grasshopper or a grasshopper]

[What is the difference between crickets, grasshoppers, grasshoppers, grasshoppers, and locusts, I have never understood]

[Hey, hey, is it time to discuss biology, this thing is so big, it's already a disaster??? 】

It can be seen from the refresh rate of the barrage on the screen that the audience is very confused at this time, and the desire to express it is very strong.

Besides, if it were really locusts, the scale in front of them would be too large.

From the audience's point of view, it can be called a locust plague.

You can't eat people, right?

In the eyes of many people, locusts and piranhas are the same type of creatures, once they gather in swarms, they cross the border without a single piece of armor, and there are white bones, and there are gnawed bones everywhere.

"There are no locust plagues, but there are more of them, and they look scary."

In the face of the locust swarm that frightened ordinary people, Bi Fang didn't move, just pulled the animal skin on the side over, preparing to block it when the time came.

[Isn't it, that's not much?] 】

[How terrible is the real locust plague? 】

"The wave in front of us is relatively light, and if it is serious, it will not be what it is now."

"You'll see a puff of black clouds, thousands of times denser than they are now, almost blocking out the sun, and that's the real plague of locusts, and there's not a single grass left after the crossing."

"When they fall to the ground, they don't even have a place of their own, so they can only lie on their companions, forming a second or even third layer of flesh blanket."

Everyone imagined such a scene in their minds, and they couldn't help but shudder.

That's too scary, isn't it all green-brown lakes under your feet?

"But even if you encounter a locust plague, you don't have to worry about endangering yourself, the locust plague is only extremely destructive to plants and crops, they basically don't eat meat, unless they are too hungry to eat a little dying animal or animal carcasses, otherwise don't worry about the locust crossing will gnaw you into a pile of bones, that's impossible."

"If you encounter something, just wrap it up, be careful not to be bitten, or hit it in the eye, and the rest is basically fine."

As he spoke, Bi Fang grabbed the animal skin on the side in his hand and draped it over his body, covering himself and Harley.

The locust swarm looked slow, but that was the illusion that the target was too big.

In fact, locusts move very fast, moving an average of more than 100 kilometers a day, and after deducting the feeding time and rest time, the sheer speed is amazing.

"Kenya has been the hardest hit by locust plagues, or rather, the whole of East Africa."

Bi Fang's voice became louder, and with the approach of the locusts, the sound of friction was already very obvious.

"Kenya is close to the tropics and the climate is not cold, so locust plagues can occur at any time, and I remember that since November last year, 75 swarms of locusts have been monitored in Kenya."

"The largest group even formed a 60-kilometer-long and 40-kilometer-wide locust belt, covering an area of about 2,000 square kilometers, with more than 100 million locusts per square kilometer!"

[, this is too exaggerated]

[Is there nothing wrong with determining the unit?]

[That's hundreds of billions! 】

Due to the large coverage area, it is difficult to exterminate locusts all at once.

They will spread everywhere, African desert locusts can not only wreak havoc in many African countries, but also can cross Europe, Asia, Africa, from East Africa to West Asia, South Asia, Southern Europe and other places, sometimes even fly to South America, running half the world.

With such a large area, it is difficult to catch them all at once.

And if the locusts lay eggs in the soil, then the locusts on the ground will be eliminated, and after a period of time, the eggs in the soil will hatch into locusts, and a new batch of locust plagues will be formed, which will lead to the continuous appearance of locust plagues.

Even in China, it has taken decades of long-term, firm, and highly organized effective governance to barely restrain it from swarming, and even this happens from time to time, let alone a fully backward and low-organized Africa.

In the midst of his thoughts, the locusts finally came to the crowd.

The first to appear was a locust that fell to the ground.

Bi Fang lifted the corner of the hide, and saw it land on a green grass, and the opener gnawed at it with great speed.

Soon, one by one, the locusts rained down and gnawed the grass like their previous companions.

"In the real locust plague, the density of locusts is very large, up to 5,000 per square meter, and the total weight is about 10 kilograms, and the total weight of 3 million locusts per acre of land can reach six tons."

"Under normal circumstances, in arid areas, only two or three acres of grain fields can have a ton of straw, and only 40,000 or 50,000 locusts are needed to eat it in an hour."

"If there is a locust plague, it will be less than a minute."

"The most important thing is that locusts eat more than twice their body weight every day, and they can eat up all the crops in an area in a day."

Bi Fang watched and explained.

He could clearly feel the locusts also falling on his back, the skin, but because there was no food, he jumped away again.

Under a meticulous close-up look, Bi Fang and the audience also saw several locusts inserting their tails into the dirt.

Apparently breeding.

"Normally, locusts are scattered, and they are severely 'social phobia', and they will avoid physical contact with their own kind, but in some cases, such as suitable living conditions, more food, locusts reproduce happily, and the population density increases, so it is a little difficult to keep a distance from other insects."

"In this case, if they are frequently touched on their hind legs, their brains will secrete serotonin and other pheromones, and the locusts will become social and the whole process will only take a few hours."

"Note, only the hind legs can trigger the 'brainwashing' effect, not other parts, as for why, I don't know, it belongs to something that is still being studied."

"The social locust is a completely different thing, and it even changes its structure, becoming more able to eat and fly, and although it is not more able to live, the quality of the eggs has become higher, and the color has also changed, from green to yellow or black."

"And the smell will always attract other locusts to join the team, and the locust swarm will continue to expand, and there will be not enough food to eat, and it will start a big migration, all the way to migration, all the way to multiply, all the way to attract new locusts to join, and of course all the way to eat food."

"Thus began the plague of locusts."

"The number of waves we have encountered is not very large, but it is conceivable that it may not be long before they become what I call 'black clouds'."
