When Xiao Weiwei explained, Liu Danqing, who couldn't stay idle, cut down a small tree and made a girl spear.

The spear was more than two meters long, one end was sharpened, and the other end was made out of a tree branch to create a Y-shaped line, which was specially designed to catch snakes.

After Xiao Weiwei's science lecture hall, Liu Danqing's spear was almost made.

A few minutes later, he handed the made spear to Xiao Weiwei and said, "Weiwei, the task of grabbing protein is up to you." ”

After Xiao Weiwei took the spear, the two got up again and continued to explore.

"Audience friends, it's not that I'm lazy, now my main task is to open the way, and the hunting work can only be handed over to Weiwei. Liu Danqing said as he walked: "There is only one principle in the direction we are walking now, that is, to go to a low place, in fact, it is difficult to distinguish between high and low terrain in the rainforest, and we can only rely on feeling and experience." ”

Using a knife to cut off a vine blocking in front of him, Liu Danqing said in surprise: "Weiwei, look, there is a big ray of sunshine in front, there should be a stream, let's go over now." ”

In the Amazon rainforest, sunlight generally shines through the gaps between the leaves, which is why the Amazon jungle is so humid, and if there is a large strip of sunlight, it means that there is a long, treeless area, which in the Amazon basin is usually a creek.

"Found it, Xiaoxi, haha!" Liu Danqing accelerated the frequency of the mountain knife in his hand, quickly walked to the light belt, looked at the creek in front of him and smiled: "Weiwei, come and see, we have found Xiaoxi." ”

Xiao Weiwei was actually a few meters behind him, and before he could finish speaking, she had already walked to the stream.

The water level of the creek is very low, about just over a meter wide and less than two meters, and the water is very turbid, and it is full of fine suspended matter when exposed to sunlight.

However, Liu Danqing was still very happy and said: "Great, it took more than five hours for us to finally find the stream, and then we can look for a bigger stream or even a river along it." ”

Xiao Weiwei frowned and said, "Qingqing, this stream looks lifeless, and it is also very turbid, it doesn't look like living water at all." ”

Liu Danqing was full of confidence at this time, and said: "There is a very simple method to judge whether a stream is living water and the direction of the water flow, this method I once used in the Louisiana swamp in the United States, I don't know if you still remember it." ”

As he spoke, he plucked a leaf and threw it into the stream, and the next thing he saw was the leaf drifting slowly toward their right hand, slowly, but firmly.

"Well, now that we've made sure it's living water, the next thing we have to do is follow the direction it flows until it joins a larger stream. ”

Xiao Weiwei was still suspicious at this time, and said: "Qingqing, how do we know that this stream will not take us around in circles in the jungle? There are countless streams in the Amazon jungle, you see it, it will turn a corner after walking a few steps, should we follow it around in the jungle?"

Liu Danqing stopped and twisted his head at her, motioned her to follow the pace, and said: "Weiwei, you have to believe in it, but also believe in physical knowledge, the water flows low, no matter how we go around in circles, we follow it, we are always reducing our altitude, continue!"

"After a little more walking, we will have to set up camp, I don't want to be in the Amazon at night, to put it in a more pretentious 13 words, that is, this place does not belong to humans during the day, but belongs to the dark species at night. ”

"In the Amazon basin, anacondas, jaguars, and cougars are all creatures that come out at night to feed, and the dark jungle is their home turf, and we can only hide in shelters and wait for the dawn. ”

"Hey, look over there!"

Just when Liu Danqing was talking about a boring topic, Xiao Weiwei interrupted him and happily pointed to the distance.

Xiao San immediately gave her a close-up of the direction of her finger, and saw some small dark green leaves exposed in the gaps in the trees.

"Huh, bamboo leaves? Liu Danqing also looked at it, and then immediately became happy.

"Sure enough, walking along the stream, in addition to being able to point out the direction, there are also a lot of surprises! ”

The excited two did not follow the creek again, but directly opened a passage between the jungles and walked to the bamboo forest.

It is a bit of an overestimation to say that it is a bamboo forest, and it can only be said that this is a large bamboo bush.

In the Amazon jungle, even the overbearing bamboo is not domineering, and can only occupy a small area by the creek to compete with other plants, instead of using the bamboo whip to expand the Dafa and grab the entire territory like other places.

This piece of bamboo is quite thick, a bit like the very popular moso bamboo in China.

Liu Danqing knocked a bamboo body with a diameter of 10 centimeters with a mountain opening knife, and introduced it in the sound of "bang bang bang": "This is Guaduo bamboo, a large bamboo unique to South America, which is widely used in the local construction industry, just like we used to use moso bamboo on a large scale." ”

"You see, its leaves are very long and narrow, so it is also called narrow-leaved melon bamboo, and its other distinctive feature is the hard bamboo branches, you see, the branches of this kind of bamboo are like steel wires, extremely hard. ”

Looking up at the sky, the sun had long been gone, and Liu Danqing could only judge the approximate time by the slope of the sun.

"Looking at the slope of the sun, it's not early, Weiwei, let's set up camp around here, relying on this piece of bamboo, we can just make a fire and make tools. ”

Xiao Weiwei nodded and said, "Okay, it's good over there, the terrain is quite high, and it's flat, you can see if it's okay there." ”

The place Xiao Weiwei said was in the middle of two big trees, because the branches of the big trees were luxuriant, blocking the sunlight, so there was only some small grass growing underneath, and no other shrubs and trees existed.

Liu Danqing took a look, nodded and said: "Good place, about five or six meters high from the water surface, even if it rains heavily at night and the water level soars, it shouldn't be able to flood us, that's it, I'll cut down this dead bamboo first, and point to it on fire." ”

"Okay" Xiao Weiwei nodded and said, "I'll take a turn here a little bit to see if there are any fruits or anything." ”

"Well, stay safe, call me if you have something. Liu Danqing responded, and saw that he had cut down the withered bamboo with a click.

This dead bamboo is quite thick, about seven or eight centimeters in diameter, it is considered an adult bamboo, I don't know what caused it to die young.

Liu Danqing quickly cut it off, then cut it two-thirds of the way up the bamboo, looked inside, and then swung the knife again, cutting off a section of bamboo with the thickness of an arm.

"This bamboo should have died not long ago, so there was no leakage at all, it was very dry inside, which is a very good phenomenon, you know, in the Amazon jungle, it is not easy to find dry living materials, to put it simply, we put a dry napkin here, and after two hours, it becomes a wet tissue. ”

"But the outside of the bamboo has a layer of bamboo slivers, which are completely waterproof, they block the invasion of humid air, so that the inside of the bamboo can stay dry. ”

Bringing the dead bamboo divided into three back to the selected campsite, Liu Danqing moved a stone and sat down, and then divided the bamboo section into two.

"First of all, I need to scrape some velvet, dried bamboo is a good raw material, I first cut off the bamboo strips, and then use a mountain knife to scrape constantly, you see, these plush bamboo velvet is the material I will use to make a fire. ”

After scraping a small pile of velvet, Liu Danqing went to cut a small pile of bamboo sticks, followed by bamboo slices, and bamboo branches.

"As always, I'm going to have to prepare fires of all sizes now, and when you start a fire in the wilderness, don't ever think of being lazy, because you'll be stolen by laziness. ”

"Now, I'm going to continue making fire tools, I turn over half of the bamboo section, and then use the mountain opener to dig a small horizontal gap, this gap must not be large, almost as big as the cut bamboo section, if it is big, it will be useless. ”

Next, put a portion of the velvet into the inside of the gap and press it with this piece of bamboo. ”

Finally, the other half of the bamboo is clamped with the foot, let it stand up, and then the gap is buckled in against the upward side of the bamboo piece, rubbing and rubbing, which is the technique of making a fire. ”

Just when Liu Danqing kept rubbing and rubbing, Xiao Weiwei, who had gone out to explore, came back, not bringing back any fruit, but dragging a large stack of palm leaves.

"I'm back, I'm coming back, I'm bringing some palm leaves, there's a few palm trees over there, I'm going to pick a little more, yo! It's a new way of life, fortunately, I came back early, otherwise when you start a fire, won't you be able to learn new skills?"

Liu Danqing did not raise his head and said: "This is the bamboo friction method to make a fire, you see the part of the bamboo friction, has it turned brown? After a while, it should smoke, using bamboo friction is a good way to make a fire on the island in the humid tropical rainforest, but there is a premise, it must be yellow bamboo, do not find a green, tender dripping bamboo to rub and rub, so that even if the friction is old, it may not be able to rise fire." ”

Xiao Weiwei didn't continue to pick palm leaves at this time, squatting next to Liu Danqing, watching him rub and rub expectantly.

"Weiwei, don't look at it, come, let's use the sawing method, now this method, it's too tiring. ”

After more than ten minutes of tug-of-war, green smoke began to rise from the friction site, followed by white smoke.

Liu Danqing hurriedly turned over the bamboo segment, poured the smoking bamboo velvet on the pile of bamboo velvet next to him, held it together with both hands, and blew it gently.

With a large amount of white smoke filling the air, there was a thud, and orange-red flames finally appeared in the rainforest.
