After lighting the fire, Liu Danqing began to build a tripod next to the fire.

It's very simple, find three long branches, tie them up at one end, and spread them on the fire.

Xiao Weiwei, on the other hand, walked to the auxiliary tank with an empty mineral water bottle and carefully poured the African elephant's bath water into it.

After settling all the way, it was placed on the ground for a while, and now the water poured out is very clear, no longer cloudy as before.

Finding a stripped-off copper wire, Liu Danqing tied two mineral water bottles to both ends of the copper wire, and then hung them on the triangular brace.

The flames began to lick the plastic bottles of the mineral water bottles.

"The next thing is to wait, wait for our water to boil for three to five minutes, and then we can drink. ”

"Don't look at the elephant bathing place where we fill the water, the water is also muddy, but the quality of the water is actually very good. ”

"Every day, the evaporation of the sun and the drinking of the animals consume a lot of water in the pond, and the groundwater is constantly converging into the pool, creating a living water cycle, like our well. ”

"There are very few viruses and bacteria in the living water, and now we have a fire to boil them, and we get very good quality drinking water. ”

After a while, the water in the two mineral water bottles began to bubble, then more and more bubbles, and finally began to boil.

"Look closely. Liu Danqing pointed to the water bottle and said: "Now the water is boiling, but the water is still basically transparent, which means that there are few impurities in the water." ”

"I don't know if you remember, in the mangrove swamp of rice, the water we beat becomes very cloudy after boiling, and it will emit a foul smell, which is the opposite. ”

Xiao Weiwei looked at the boiling fresh water in the water bottle, suddenly thought of something, and said to Liu Danqing: "Qingqing, we still need two bowls, so that we can pour out the boiling water and drink it first, and at the same time continue to boil the water." ”

Liu Danqing patted his head and said, "Why didn't I think of it, you wait, I'll get it." ”

He got up and went to the tree next to him, cut a branch the thickness of a calf, cut off a section of about thirty centimeters, and then erected it and cut it in two from the middle.

"Come, Weiwei, let's dig up the wood in the middle with a mountain opener, and it's two water bowls. Handing a piece of wood to Xiao Weiwei, he continued: "This tree is called African neem tree, and this neem tree is also African mahogany, which is relatively soft and easy to process. ”

"Although the texture of this wood is relatively soft and not strong, for us, easy processing is king, and without the tools at hand, wenge wood like the one I have is too difficult to process. ”

While processing, Liu Danqing took the topic away again.

"In this forest, I have seen two kinds of precious trees, the one behind me is a big chicken wing, also known as African cliff bean wood, which belongs to a kind of mahogany, just when I was on the road, I also saw a few East African black sandalwood, also called Shen Huai Bao, which is also a kind of mahogany. ”

"So Africa is rich in resources, I have to take it, if these trees are put in China, they are all good things that can be auctioned, and in Africa, they abound. ”

The audience was very excited when Liu Danqing said this.

"Master Qing, send the coordinates, I'm going to cut down the tree. ”

"Cutting trees to make a fortune, just now, comrades, I'm going to Africa to cut down trees. ”

"Let's go together, sister, it's wenge wood and sandalwood, good guy, I just checked it, it's all valuable goods!"

"Friends, you don't have the ability of Qing Ye Weiwei, and you also want to go to Africa and feed wild dogs?"

……

After digging the bowl, the two dug out a groove in the ground and put the long wooden bowl on the groove.

Remove the water that had been boiling for a few minutes, carefully pour it into a wooden bowl with a leaf support, and when a bottle goes down, it is only half a bowl poured, and it is steaming.

Liu Danqing first poured the water, picked up the auxiliary water tank again, filled the mineral water bottle in his hand, and then took Xiao Weiwei's mineral water bottle and filled it too.

While pouring water, Liu Danqing said: "The mud content in this water is so high, you see, it's okay now, the water poured out is relatively clean, but the water in the water tank has become turbid again." ”

"It seems that after these two bottles are burned, we will have to find a way to let the water settle twice. ”

"Secondary precipitation?" Xiao Weiwei wondered: "What is that, a physical term?"

"Uh......" Liu Danqing hung the water bottle on the triangular brace to continue boiling water, and said embarrassedly: "My current vocabulary is to pour water into our wooden bowl, precipitate it, and then pour it into the mineral water bottle to continue to burn." ”

Xiao Weiwei looked at Liu Danqing a little speechlessly, can you not pretend to be 13.

Liu Danqing also looked at Xiao Weiwei speechlessly, sister, it's hard to dismantle!

After looking at each other for a while, Liu Danqing got up again, cut down a piece of wood, cut it in two again, handed it to Xiao Weiwei and said: "Weiwei, idle is idle, make two more wooden bowls to precipitate the sediment in the water." ”

After working for a while, the two of them were idle, drinking water from a wooden bowl while holding their mobile phones to interact with the audience.

This kind of leisure time lasted until about half past two, Liu Danqing looked at the sun and said, "Weiwei, I will climb this big chicken wing tree, look at the terrain in front of me, and then say, you are alone and be careful below." ”

Xiao Weiwei nodded and said, "No problem, don't be verbose, hurry up." ”

This large winged tree is fifteen or sixteen meters high, and the diameter of the base is about seventy or eighty centimeters, and it can be regarded as standing out from the crowd in this forest.

Liu Danqing's tree-climbing skills were basically full, so he climbed fast, and in just two or three minutes, he was already standing on the branches on the top of the tree, looking at the situation in the west.

"You see, to the west of us, the vegetation is obviously much more lush, with patches of dark green interspersed with gray-brown, and that's the edge of the Okavango River Delta. ”

Coming down from the tree, Liu Danqing said to Xiao Weiwei: "Weiwei, let's clean up our things, you go and dump the sediment in the auxiliary tank, and I will make a fire fold." ”

"The fire fold is a kind of portable fire that was often used in ancient China, and I will not introduce the specific method, but now, I want to make an African version of the fire fold. ”

Taking the blanket containing the elephant's poop, he rummaged through it and took out the driest one.

The poop was the size of Xiao Weiwei's head, and it looked like a mass of rotten and fermented grass drying again.

Liu Danqing broke the poop and said, "Now, I will open the poop, then pick up two pieces of fiery red charcoal and put them in the middle, close it, press it tightly, and wrap it tightly with the copper wire that has just tied the mineral water bottle." ”

"Well, an elephant poop version of the fire fold is ready, although the appearance is completely different from the traditional fire fold, but the principle is the same, in physics it is called "re-ignition", which refers to the phenomenon that things that are already burning are in a state of half-burning and half-extinguishing due to lack of oxygen, and when they get new oxygen, they immediately begin to burn. ”

With a blanket on his back, he tied the fire fold to the spear, and then put the spear on his shoulder, Liu Danqing shouted: "Let's go!"

The two set off again, heading west.

Out of the woods, there was another yellow savanna.

Along the way, the two saw zebras, takin, steppe deer, and even a bunch of African black rhinos, but neither had any intention of hunting.

"If you look closely, the herbivores in Africa are completely different from the reindeer we met in Iceland, and they are very vigilant, like the zebras. ”

"Weiwei, if you take a closer look, can you find anything. ”

"Hmm!" Xiao Weiwei stared at the group of zebras for a while, and suddenly realized: "Qingqing, there is a zebra that has not lowered its head to graze, and is looking at the surrounding situation. ”

When the audience heard this, they all suddenly realized.

Sure enough, one of the zebras in the group had been standing there, turning his head to look at the wind and grass around him, like a sentry.

Liu Danqing nodded and said: "In Africa, all herbivores, except for elephants and rhinoceros and long-standing deer, can only be said to be a lot of herbivores, their vigilance is very high, and a sentry will be arranged every moment, once the situation is found to be wrong, the sentinel will run away quickly." ”

"So, if we want to use the same hunting method on the glacier, it's useless, and before I get close, these animals will run away, and with the little short legs of humans, there's no chance of catching up with them. ”

"Huh!" Xiao Weiwei suddenly interrupted Liu Danqing's words and said, "Qingqing, what is there? In that grass, is it an African python?"

Following the direction of Xiao Weiwei's finger, Liu Danqing's face changed.

"Comrades, it's time for the two of us to pretend again, it should be a black mamba snake, about thirty meters away from us. ”

"A big road can make Weiwei, a foodie, mistake it for a black mamba of an African rock python, you can imagine how big it is, Xiao San, go take a picture, Weiwei, let's take a little detour. ”

It was a large brownish-gray snake that did not look black at all, but its body was massive, roughly estimated to be more than three and a half meters, and probably nearly four meters long.

As Xiao San approached, the Black Mamba lifted a section of his body in front of him, puffed out his neck, and opened his mouth, possibly posing a threatening gesture towards Xiao San, probably taking Xiao San as his natural enemy, the African snake vulture.

At this time, everyone finally understood the origin of the name Black Mamba.

Its large open mouth revealed a jet-black mouth, which looked particularly evil.

And Liu Danqing and Xiao Weiwei, who were detouring in the past, also breathed a sigh of relief.

"Comrades, it's not that we are too incompetent, but that the enemy is too ferocious, a black mamba that is longer than our spear of more than three meters, if you can't provoke it, you won't provoke it, in addition to biting people and injecting venom, they will also spray venom, the larger the black mamba, the greater the amount of venom sprayed, and the faster the speed. ”
