Live Wilderness Challenge

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

"Ants are similar to bees. They are also social insects good at building. They are afraid of fire and smoke. It has been scientifically proven that they rely on carbon dioxide concentration to perceive complex building structures."

"Moreover, many of the ants communicate with each other by secreting pheromones themselves. The strong irritating smoke can cover up the pheromones, causing them to lose communication, causing panic and confusion."

During the process of explaining, Chen Xu had already started looking for flammable tinder and stuffing nearby.

After searching for a long time, he finally found a dead tree in the jungle.

"This kind of dead wood is very suitable as tinder, but one thing everyone needs to pay attention to is that because of the heavy humidity in the tropical rainforest, even if it is dead wood, the outer layer is still a little damp."

"And damp tinder is extremely difficult to ignite. If you don't pay attention, if you use wood to make fire, you will only waste a lot of time and energy in the end, and the gain will outweigh the loss!"

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

Afterwards, he sat down, peeled off the outer skin of the stick, and then put the backpack on his lap, like sharpening a pencil, and used the tracker to peel off the wood from the dead wood one by one.

"I didn't bring a lighter, only a pair of flint and steel, so it's unrealistic to directly light dead wood. I can only make a ball of tinder first. This method of shredding is very simple and effective."

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

In less than 3 minutes, he had already chipped a lot, and a small pile of wood chips had been piled up on the entire backpack.

Then, he grabbed the wood chips and rolled them into a ball, "See, the dry wood chips have a lot of space in the middle, which is convenient for air to support combustion. It's very suitable for making tinder!"

Seeing this, the audience couldn't help admiring Master Xu's ingenuity, even the tinder was so beautifully made.

In fact, they were right. After Chen Xu upgraded his tool-making skills, his manufacturing skills had indeed improved a lot.

Next, Chen Xu took out the flint and steel, because it has excellent tinder as the foundation, and the flint and steel is much more advanced than the primitive method of "drilling wood to make fire". White smoke, and then flames burst out.

Seeing that the tinder was ignited, he hurriedly picked up the dead leaves and branches that had been prepared by the side and piled them on, and the fire grew stronger.

"Okay, then we just need to prepare a large piece of leaves!"

The corner of Chen Xu's mouth curled up. For the tropical rainforest, the most indispensable thing is plants. This kind of large leaves can be picked nearby.

"I have also told you before that there are two factors that cause smoke when burning. One is insufficient temperature, and the other is insufficient oxygen. Therefore, the easiest way is to burn the wet leaves, and the mesophyll will cool down when the water evaporates. , producing steam, forming smoke”

"Then it is to wrap the burning material as tightly as possible to reduce the contact area between the burning material and the air, thereby reducing the intake of oxygen."

For these things, he has long been familiar with the road.

After the few paragraphs were finished, he also found the leaves here, wrapped the burning thing, stuffed it with fresh leaves, and finally tied it up with vines, leaving only a small exit in front.

as predicted.

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

"almost!"

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

Because there are too many bugs in the tropical rainforest, except for mosquitoes, other kinds of poisonous insects and flying insects, not to mention the number, the types alone cannot be counted with a few hands.

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

Otherwise, after this night, he would definitely be bitten into an idiot by the bugs in the rainforest.

When I came to the dead wood, I could see that the Red Fire Ant colony that was alarmed by Chen Xu had returned to the nest again, leaving only a few dozens of worker ants at the "door" to continue to act as guards.

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

Then, he ran out without looking back.

Thanks to his quick retreat, the thick smoke lingered under the dead wood for a long time, and within a few seconds, a large number of fire ants rushed out from under the dead wood, as if a cart of rice had been sprinkled down.

There was a "crash", and as far as the eye could see, there were red fire ants all over the ground.

The audience could tell that they were very flustered, not at all as orderly as when they besieged Master Xu just now.

And among them, many red fire ants just escaped from the thick smoke, stopped on the ground before taking a few steps, and did not move anymore, perhaps they were suffocated to death by the high temperature or the thick smoke !

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

And at this moment, a group of ants also ran out of the thick smoke.

What's interesting is that although the group of ants was flustered, they didn't disperse. They kept their formation and moved quickly towards the outside.

The corner of his mouth curled up: "It's the queen. Ants are extremely social insects. The internal hierarchy of the group is very strict. The queen is the core of the entire ant colony. For soldier ants and worker ants, she is a god."

"Conversely, soldier ants and worker ants are just tools to her. In such a catastrophe, all worker ants will be desperate, even if they sacrifice themselves, to rescue the queen first and then take her away."

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

"Nimma, this ant queen is really nothing, she's a green tea whore!"

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

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

Chen Xu looked at the barrage and couldn't help laughing. After observing for a while, he set off and said, "The ant queen has evacuated, and the remaining ant colony is no longer viable. Let's take down the ant nest as soon as possible!"

After saying this, he rushed towards the dead wood with a machete in his hand.

Without the ant colony, he let go of his courage and directly lifted the dead wood. After finding the ant nest, he picked up the machete and chopped towards the root of the ant nest.

The ant nest looks similar to a bird's nest, like a gray rotten wood.

While Chen Xu was chopping, there were still many red fire ants left from various exits.

Chapter 672 The sky is about to change

Some viewers couldn't help but feel a little distressed when they saw this scene. After all, this can be regarded as destroying the home that the red fire ants have finally built.

Regarding this, Chen Xu shook his head and smiled, and explained: "Fire ants in Latin mean invincible. They originated in South America and then quickly spread all over the world. Due to their terrifying aggressiveness, they are also defined by the IUCN as the most One of the most destructive invasive organisms."

"In 98, there were two cases of death from fire ant bites in the United States. In 04, the first case of death from fire ant bites occurred in China. In 15, a large number of farmlands in Guangxi Province were destroyed, and it was also the culprit."

"So, when we destroy its ant nests, we are actually maintaining the rainforest environment in Borneo in disguise."

When the audience heard this, they didn't expect the harm of red fire ants to be so great, and the little sympathy left in their hearts was also thrown aside.

After removing the ant nest, Chen Xu stamped out the thick smoke, and then left quickly.

With the aggressive and retaliatory nature of the red fire ants, if they continue to stay, maybe the queen will lead the soldier ants and kill them back.

"Unfortunately, this is near the equator in the southern hemisphere. I told you before on the Matterhorn in the Alps that ant nests in the northern hemisphere generally face south because of the consideration of lighting."

"But near the equator, since the difference in the sun's inclination angle throughout the year is not too large, the opening of the ant nest cannot be a guidepost to guide the direction."

"Everyone must pay attention to this point. Sometimes, a wrong direction will bring a lot of trouble, especially in the process of survival, if you get the wrong direction, it will even directly end your hope of survival!"

Chen Xu told everyone too much about survival in the wild, survival knowledge, and skills. At first, some people didn't fully believe it.

Until those knowledge and skills have been confirmed one by one, now, as soon as he speaks, the audience will nod like chickens pecking at rice, while memorizing it by rote.

After stealing the ant nest, only 10 minutes have passed.

However, since there is a colony of red fire ants nearby, no matter how good the terrain is, it is not suitable for continuing to build a campsite.

Therefore, Chen Xu could only continue along the creek and continue upstream, looking for a new camping place by the way.

It took about half an hour to walk.

The sound of water flowing ahead began to grow louder.

He raised his eyebrows, "Judging from the turbulence of the voice, we should be approaching the source of the stream!"

And at this moment, all of a sudden.

Boom-!

A huge shock came from the sky above the jungle, and Chen Xu suddenly raised his head. Unknowingly, a group of black cumulus clouds appeared above the sky!

Since he had been in the jungle before, the sky was completely blocked by tall trees, and it is now the rainy season in the tropical rainforest. The torrential rain is fierce and unpredictable. It may be sunny one second, and it will rain down in the next second. heavy rain!

"Oops! Judging from the size of the cloud cover, this rainstorm will not be small!"

Chen Xu frowned. For him now, there is no shelter from the wind and rain, and it will be dark in a few hours.

This torrential rain will wash away all the plants in this area of ​​Borneo. At that time, it is likely that even starting a fire will become a problem!

"Brothers, we must speed up!"

After speaking the last sentence to the camera, Chen Xu no longer saved his energy, and rushed directly to the upper reaches of the creek.

At this time, the most important thing is to quickly find a suitable camping site to build.

He never thought of hiding under a certain tree to temporarily take shelter from the rain. You know, it is the rainy season in Borneo, and who knows how long the rain will last.

If it goes down until night, wouldn't it be trapped under the tree alive?

At that time, let alone lighting a fire, sleeping will be a problem!

Therefore, Chen Xu would rather face the rain than finish the preparatory work first!

Before setting off, his sprint burst skill had been upgraded to full level.

Although the jungle is muddy, relying on his flexible body and the stable foundation left by mixed martial arts, he can at least move smoothly, not to mention being as fast and agile as clouded leopards and gibbons in the jungle.

Three minutes later, a mountain stream appeared in front of his eyes.

In the eye, there is a small waterfall with a height of only seven or eight meters. It can even be said that this scale is not even a waterfall.

The stream flows down from the mountain stream, rushes to the ground, flows down the gully, and becomes a stream, so this is the source of the stream.

Chen Xu shook his head, "The terrain here is flat enough, but it can't be used as a campsite. Once the heavy rain falls, the water level will soar instantly. When the mountain torrent rushes down from the mountain stream, the first one to be submerged will be here!"

"We have to find a way to climb up. There seem to be a few vines on the right side of the waterfall. Let's go there and try!"

The news that the rainstorm was coming made him very anxious, but no matter how anxious he was, he still couldn't make some fatal mistakes.

Afterwards, Chen Xu came under the cane and tugged hard, "There is no sign of looseness, it should be able to bear my weight!"

After finishing speaking, he grabbed the vines with both hands, stepped on the hillside with both feet, and started to climb up with a sudden breath in his chest.

The hillside of seven or eight meters, no matter how muddy and steep the slope, was not a problem for him.

Two minutes later, Chen Xu arrived at the mountain stream smoothly.

The top is still a forest covered by trees, but the ground is quite different from before.

When you look at it, you can see puddles reflecting light everywhere, a lot of moss and dead leaves, just floating on the water.

Here is a swamp!

It seems that the water source of the creek comes from here.

"call……"

After seeing this scene, Chen Xu frowned, took a deep breath, and let it out again.

After a while, the restlessness in his heart was suppressed.

"It's too bad for us to encounter swamps at this time. The swamps will seriously delay our speed. Moreover, the swamps in Borneo are likely to be inhabited by cold-blooded killers such as crocodiles and pythons."

In fact, needless to say, just thinking about the swamps Xu Ye encountered before is enough to make the audience feel terrible.

Imagine that when you step into the swamp, the puddle swallows most of your legs, and you never know how deep you will go next.

Even, you can't even predict what's on the bottom of the water!

In case, when the time comes, a crocodile suddenly jumps out from the swamp with a bloody mouth, let alone dodging, if you can not be scared to death on the spot, it will be considered good!

"In any case, there is a swampy environment with rich water content, so it is even more impossible to camp under the mountain stream. Before the heavy rain falls, we have to get out of here as soon as possible!"

Chapter 673 Shelter

After speaking, Chen Xu took a step forward.

And with this small step, his entire shoes were completely submerged in the water.

"Fortunately, the periphery is not too deep. According to the method I explained to you before, we need to find a long enough dead wood to use as a walking stick!"

So, he walked along the shallow swamp outside, first walked to the edge of a bush, pulled out the machete, and cut off a branch as a crutch.

With it helping to find the way, Chen Xu became much bolder.

At least, he knew that he would not step into a deep pit or muddy swamp for no reason, and be swallowed alive!
