", Xu Ye is so bold, he is not afraid of being bitten again?"

"I shudder at the thought of being covered in ants!"

"Xu Ye's blood is thick and high, don't be afraid!"

In the live broadcast room, many people are worried about the siege of red fire ants, but Chen Xu came up with a solution: "Use fire!"

"Ants are similar to bees, they are also social insects that are good at building, they are very afraid of fire and smoke, and it has been scientifically proven that they rely on carbon dioxide concentrations to perceive complex building structures. ”

"Moreover, many of the signals exchanged between ants rely on their own secretion of pheromones, with a strong irritating smoke, which can mask pheromones, make them lose communication, and cause panic and confusion. ”

In the process of explaining, Chen Xu had already begun to look for fire velvet and filler nearby that could be burned.

After searching for a long time, he finally found a piece of dead wood in the jungle.

"This kind of dead wood is very suitable for fire velvet, but one thing to note is that because of the heavy humidity of the tropical rainforest, even the dead wood is still a little damp on the outside. ”

"The damp velvet is extremely difficult to ignite, if you don't pay attention, if you use drilled wood to make fire, you will only waste a lot of time and energy in the end, and the gains outweigh the losses!"

Before lighting the fire, Chen Xu specially reminded the audience.

Then he sat down, peeled off the outer skin of the stick, and then put his backpack on his lap, and cut off the wood from the dead piece of wood like a pencil, with a tracker.

"I didn't have a lighter, only a pair of flints, so it was not practical to ignite the dead wood directly, so I had to make a ball of velvet first, which is a very simple and effective way to sharpen the wire. ”

Chen Xu said while demonstrating the specific steps to the audience.

In less than three minutes, he had already sharpened a lot, and there was already a small pile of sawdust silk on top of the entire backpack.

Then, he grabbed the sawdust silk and clumped it into a ball, "See, the dry sawdust silk ball, and there are a lot of gaps in the middle, which is convenient for air combustion, and it is very suitable for making velvet!"

Seeing this, the audience had to admire Xu Ye's ingenuity, even the velvet was so good-looking.

In fact, what they think is right, after Chen Xu upgraded his tool manufacturing skills, his manufacturing skills have indeed improved a lot compared to before.

Next, Chen Xu took out the flint, because there is an excellent velvet as the base, and the flint is much more advanced than the primitive method of "drilling wood for fire", after a while, the sawdust silk rose white smoke, and then burst out of the flames.

Seeing that the velvet was lit, he hurriedly picked up the dead leaves and branches that had been prepared next to him and piled them up, and the fire was able to grow.

"Okay, let's just prepare the big leaves!"

The corners of Chen Xu's mouth curled, for the tropical rainforest, the most important thing is plants, this kind of large leaves, can be picked nearby.

"I have also told you before that there are two factors that are easy to smoke when burning, one is that the temperature is not enough, and the other is that the oxygen is not enough, so the easiest way is to burn the moist leaves, and when the mesophyll water evaporates, it will cool down, produce steam, and form smoke"

"Then the combustible material is wrapped as tightly as possible, reducing the contact area between the combustible and the air, thereby reducing the amount of oxygen intake. ”

He was familiar with these things.

After a few paragraphs, he also finished looking for leaves, wrapped the incendiary material, stuffed it with fresh leaves, and finally tied it up with vines, leaving only a small exit in front of him.

Sure enough.

After seven or eight seconds, thick white smoke began to come out of the small exit.

"Almost!"

After speaking, Chen Xu took the prepared "weapon" and returned to the ant nest of the red fire ants.

Because there are too many insects in the tropical rainforest, in addition to mosquitoes, all kinds of other poisonous insects and flying insects, not to mention the number, just the species, a few hands can not count.

Therefore, an ant nest that can repel mosquitoes is very important to him.

Otherwise, after this night, you will definitely be bitten into an idiot by the insects of the rainforest.

When I came to the dead wood, I could see that the red fire ant colony that had been alarmed by Chen Xu before had returned to the nest again, leaving only a few dozen worker ants at the "door" to continue to act as guards.

Seeing this, Chen Xu quickly rushed towards the dead wood, stared at the entrance of the ant nest, and stuffed the "weapon" directly into it.

Then he ran out without looking back.

Thanks to the speed of his retreat, the smoke lingered under the dead wood for a long time, and within a few seconds, a large number of red fire ants were seen rushing out from under the dead wood, like a cart of rice being spilled.

"Bang", as far as the eye can see, the ground is full of red red fire ants.

The audience could see that they were very flustered, and they were not at all as orderly as they were besieging Xu Ye just now.

Among them, there are many red fire ants who have just escaped from the smoke, and before they can walk a few steps, they stopped on the ground and never moved again, perhaps they were smoked to death by the high temperature or smoke!

Chen Xu hid more than ten meters away, watching the red fire ant colony continue to migrate.

And at this time, one of the ants also ran out of the smoke.

Interestingly, although the ants were also flustered, they just didn't disperse, always maintaining a formation, moving quickly towards the outside.

The corners of his mouth curled: "It's the queen ant, the ant is a very social insect, the hierarchy within the group is clear, very strict, the queen ant is the core of the entire ant colony, for the soldier ant and the worker ant, she is the god." ”

In turn, soldier ants and worker ants are just tools for her, and in the event of such a big disaster, all worker ants will be desperate, even if they sacrifice themselves, to rescue the queen ant first, and then take it away. ”

When the audience heard this, they couldn't help but sigh:

"Nima, this queen ant is really not a thing, a green tea alive!"

"Worker ants: It's on fire! It's on fire! Everyone saves the leader first! Let the leader go first!"

"23333, fellows, let's check the water meter!"

Chen Xu looked at the barrage, and couldn't help but laugh, and after observing for a while, he moved and said: "The ant queen has been evacuated, and the remaining ant colony is no longer a climate, let's quickly dismantle the ant nest now!"

After saying this, the others had already rushed towards the dead wood with the mountain opening knife.

Without the ant colony, he let go of his courage, directly lifted the dead wood, found the ant nest, picked up the mountain knife, and cut towards the root of the ant nest.

The ant's nest looked similar to a bird's nest, like a rotten piece of gray wood.

And when Chen Xu was chopping, there were still a lot of remnants of red fire ants coming out of various exits.
