The clods of earth were thrown out and fell to the ground, and the dry soil shook off countless fine grains and drifted into the air, raising a thin layer of yellow mist.

Soon, a large pit was dug out, and everyone saw that under the originally inconspicuous small roots, there was actually an extremely huge rhizome, flat and oval, resembling an oversized curling stone.

After the hard soil on the surface was excavated, the soil in the lower layer became loose, and Bi Fang stuck the dagger into the ground, dug it directly, and finally lifted the entire rhizome to the ground.

Seeing this, Harley behind him got up and stepped forward, looked down and sniffed, but didn't smell what he wanted, screamed a few times, and continued to lie on the ground, tilting his head sideways to see what Bi Fang was going to fix.

"This thing, it's quite heavy, it's a bit of a stretch."

Bi Fang took out the large rhizome, put it on the ground, patted the dust on his hands, and then pulled out the dagger and chiseled at the rhizome, the hard steel and the wood collided, making a dull bangbang sound.

In the dull background sound, Bi Fang raised his eyes and looked at the drone and said.

"I don't know if you've heard of this place in Namibia."

[I've seen the Namibian legend and has a deep impact on the polar bear in it (eating watermelon)]

【Golden compass, right?】

[Is there a possibility, that movie is called The Chronicles of Narnia]

[It's not normal to remember wrongly, and people's memory is not a reliable thing (it's not straightforward and strong)]

"Anyway, in my impression, Namibia's fame should be on par with Kenya, belonging to the T1 echelon, just like Egypt."

"When I went from Nemo Point to South America and then flew to the Sahara Desert, I looked down on Namibia through the porthole, and it was also a beautiful place."

"The desert there is not yellow, but crimson."

The beauty of Namibia can be described as "stunning".

The Namib Desert, one of the oldest and most beautiful deserts in the world

Due to the abundance of iron in the gravel, the surface of the desert turns red after oxidation.

"Oxidized red" changes a lot of color throughout the day with the change of sunlight angle.

The most amazing thing is that in the early morning or dusk, the sun shines obliquely, the morning sun is bright red on the side, and the back sun side is as deep as ink.

The two vivid colors are extremely shocking and impactful, shocking and shocking, and every arc and shadow flashes with a breathtaking arc light.

It happened to be dusk when Bi Fang flew by, sitting on the porthole, overlooking the light and shade cut out of the back of the narrow sand dune crest, half red and half black on both sides, red and black and quiet.

The 80 million years of red desert shine in the sunlight with charming colors and soft lines.

Bi Fang has always regretted that Namibia was not on his route across the Sahara, and of course, this is not the point he wants to talk about now.

"In the Marintal region of Namibia, there lived a primitive tribe called the Bushmen, who lived on that land for almost 20,000 years."

20,000 years!

The audience who heard this number was stunned.

[Is there any mistake, 20,000 years?] 】

[Did Fang Shen make a slip of the tongue, are you sure it's not two thousand years? 】

"How could I have made a mistake in such a matter, because of this, the Bushmen are considered to be the oldest indigenous people."

"The Bushmen are also known as the 'San people'. The colonists of the central kingdom named them bushman, which is our Chinese transliteration, which originally meant people living in the bushes, describing the living conditions of the Bushmen, and now it has also become a consensus name for them. ”

"As a special group, they are the most primitive people in Africa. Most live in Namibia, with a small number in Botswana and Zimbabwe. ”

"Until more than 20 years ago, the Bushmen were still in prehistoric times, and almost no one knew about it."

"The first time I knew about the Bushmen was from an article published in the magazine Ugly Country, probably in the 90s of the last century, a young female scholar came to the tribe where the Bushmen lived in Botswana, and stayed for three months."

In an academic paper, she pointed out that the Bushmen were in danger of extinction due to poor living conditions and called on the Ugly politicians to urge the Botswana government to return the jungle they occupied to the Bushmen.

[I guess the old ugly refused (dog head)]

[There is no oil underground, how can it be that you can live or not]

Seeing the barrage, Bi Fang shook his head: "No, the old clown really intervened, and the old clown directly wrote a message at that time." ”

"Then as soon as Bo Guo heard the old clown's words, he immediately made a plan to return the jungle to the Bushmen."

"But not long after the Bushmen happily moved to their original territory, geologists announced that they had discovered a diamond mine in the jungle they had just moved out of."

【！

！ 】

[It wasn't oil, it was diamonds!] 】

[My mother, this trick is too bad]

"I can't say if there's anything wrong with it, but one of the biggest topics of interest for travelers on the continent is the Bushmen."

Under the cutting of the dagger, a large amount of debris fell from the rhizome, revealing the white rhizome tissue, and everyone also saw the milky white juice bubbling in it, apparently with sufficient moisture.

"They lived in the most barren and barren desert areas, and as the earliest overlords of the land, they lived by hunting and gathering plant roots, stems and wild fruits, as in the Paleolithic period, without a fixed dwelling, often moving from place to place where they could hunt their prey."

"In order to obtain water and food for survival, the Bushmen often live in groups in the summer, and in the winter, when water and food are not enough, they begin to move in different directions as a family unit, looking for food and water. But there are also Bushmen who are forced to concentrate around the only source of water during the driest winter season. ”

"Since they make a living from hunting, in terms of hunting, they naturally have skills that other peoples do not have, and similarly, there are many unique skills in survival."

"Like the Sherpas and the Bajau people, the Bushmen themselves are very thirsty, and they have been thirsty to a certain degree, and they have a lot of knowledge about which plants can be eaten and replenished with water."

"Like the rhizome I'm digging now, it's actually taken from their survival skills, otherwise no one would have known that a small whisker that came out of the ground would have a plant underneath that could replenish moisture."

"The Bushmen would chop the rhizome into crumbs and squeeze the juice out of it to drink."

"All you have to do is scrape off the shavings with a stone or a dagger, then grab a handful and hold it hard, point your thumb at your mouth and wait."

[Humanoid self-propelled encyclopedia, terrifying! ] 】

[I often wonder if a person's brain capacity is limited]

[This sense of erudition is really fascinating]

[I always think that the boy who knows a lot is particularly attractive (shout)]

Bi Fang wiped his hands, held the large amount of crumbs that had just been cut in his hands, and squeezed his head down, and a small stream of water flowed down his thumb and fell right into his mouth.

Cool and delicious, with a refreshing feeling.

"It's a lot better than the groundwater just now, with a special fragrance."

"In fact, this water-rich plant is known not only to humans, but also to some animals, so after digging it out, the Bushmen will find the acacia tree nearby, then pull out its branches, cover it near the rhizome, and then bury the rhizome back, and after a period of time, wait for it to grow and reuse it."

Bi Fang looked around and found an acacia tree as well.

Cut off the branch with a dagger, drag it to the rhizome, and bury it carefully above the rhizome.

"Acacia is very common in Africa, it is actually a leguminous plant, and we also have some relatives in China, such as the common acacia tree in parks, we can often see it in botanical gardens, street trees, etc."

"In addition, the mimosa and the wild locust on the mountain are also members of the same family as the acacia."

"In the south of our country, there will still be a shrub-like acacia, and the locals will eat its young leaves as wild vegetables, remember the stinky vegetables I ate in the Banna rainforest? That's the Acacia. ”

"Of course, they're completely different in Africa."

"In order to survive in the brutal living environment of the local area. As food for herbivores, they have coexisted in the fight against herbivores for millions of years. ”

"As the most common type of tree in the savanna, the acacia has long thorns, and all kinds of acacia have a variety of thorns."

"Look at this, the leaves have not yet grown, but the thorns have grown quite long, and the thorns can protect the young leaves first, preventing some animals from climbing the trees, and their trunks will also have a lot of thorns, so that the animals can't climb up."

"There are also some acacias, although they don't have such long spines, but they have a kind of inverted hooked spines, which are also very powerful."

Bi Fang stuck the branch in the ground, then adjusted the direction, and finally wrapped the entire rhizome.

"That's about it."

After doing all this, Bi Fang clapped his hands: "In fact, it is impossible for us to come back, all this thing will stay here like this, maybe there will be tourists who travel here in the future to see it and use it." ”

[Animal: You are amazing, you are high]

[What about my big rhizome, where did the big rhizome go?] 】

[Lao Fang: My treasure? I can give it all to you if you want. Go find it, everything in this world is there! 】

[Since then, the era of the prairie has begun! 】

Bi Fang and Harley then walked north on the grassland.

As they walked deeper and deeper, the whole grassland seemed to become more and more lively.

The appearance of all kinds of hunters, from insects to poisonous snakes, from animals to birds, is an eye-opener.

Stones slide down.

A bulging-bellied viper fled quickly under the grass and snake of the stick, and Harley next to him was startled and almost jumped in the air, but Bi Fang just glanced at it, and didn't care too much, three meters away he found the poisonous snake hiding in the rock pile, and deliberately poked the stone to scare it away.

At this time, Bi Fang's attention was more on the big tree in front of him, and his expression was more surprised.

"Myrrh tree."

[Myrrh tree? What's that? 】

[I guess, it must be poisonous, and then the toxicity is very strong, and there is no medicine to cure it, so it is called myrrh tree!] 】

[Damn, I feel the truth]

"No, it's not, the myrrh tree itself is not poisonous, on the contrary, its resin also has medicinal properties, and it is especially good for relieving toothache."

During the explanation, Bi Fang circled around the tree, looked down at the ground, and crouched down from time to time to dig for dirt, as if looking for something.

"The myrrh tree has a word for 'medicine', and its English name, myrrh, comes from the Hebrew word murr, which means 'bitter', and has a very strong meaning in religious history."

"In the Bible, when the three wise men of the East, under the guidance of a comet, found Jesus at the age of six months, they gave him three gifts: gold, frankincense, and myrrh."

[So Lao Fang has a toothache? Or ready for backup? 】

[So what are you looking for?] 】

"Not really."

Bi Fang shook his head again, he didn't have a strong need for this big medicine.

"The myrrh tree is not poisonous, but there is a beetle that likes to parasitize it, and this beetle is very useful to us...... Found it, here! ”

With the terrifying experience of a wilderness traveler, Bi Fang soon found what he was looking for in the underground near the myrrh tree - the cocoon of the leaf beetle!

[What's that?] 】

[, what a big bug]

"A poisonous insect."

Bi Fang's explanation was concise and to the point.

Bushman hunters in African countries typically use lightweight bows and arrows for hunting, which means that bows and arrows are often not lethal enough to cause fatal damage to their prey when faced with larger prey.

However, in the vast jungle, the Creator created another deadly weapon for the Bushmen, curare poison.

The bow and arrow poison most commonly used by Bushman hunters is derived from a unique insect, the leaf beetle.

And the leaf beetle beetle usually parasitizes the plant of the "myrrh tree"!

That's why Bi Fang was surprised and pleasantly surprised when he saw it.

"These cocoons are usually hidden 0.5 to 1 meter below the surface, and each cocoon usually contains a pre-pupation beetle larva in a restrained state, which can lie dormant in the cocoon for several years."

"After obtaining the larvae or pupae of the leaf beetle, the Bushman hunter can quickly find the location of the lymph in their blood system and then squeeze the blood lymph onto the arrow with their hands."

"Sometimes in order to poison an arrowhead, it is necessary to use up to 10 larvae of hemolymph."

Bi Fang raised the cocoon in his hand, this cocoon was very huge, almost half of the entire palm, and the fat insects inside could be clearly seen through the sunlight.

"It is important to note that the hunters only applied these poisonous liquids to the tip of the shaft and not to the tip of the arrow, in order to avoid the tip of the arrow accidentally scratching the hunter's own body and causing poisoning."

Bi Fang put the cocoon into a small compartment in his backpack to prevent Jerry from stealing bad things, and once again pushed away Harley, who had come up out of curiosity.

Harley, who had never been on the prairie for so long, was curious about everything.

"The toxic substance contained in the hemolymph of the leaf beetle is a toxic protein, as we all know, as long as it is a protein, the toxicity will gradually disappear with time, but the poison of the leaf beetle is different, and it can usually be maintained for a year."

"There are three main types of beetles of the Leaf beetle family that Bushman hunters use to create curare poison."

"The funny thing is that these three species of leaf beetles will be parasitized by the walking beetles, hey, what are you talking about, you look at this."

Bi Fang found another one in the ground, held it up, and pointed to a certain part of the worm in the cocoon, and could see that there was another smaller white worm hanging on it.

"When the former forms a cocoon, the larvae of the latter take the opportunity to attach to the larvae of the former, and then lie dormant in the cocoon, sucking the host's blood and the soft parts of its body, and eventually killing the host."

"But that's not a bad thing for us, the larvae of the walking beetle are just as venomous, even more poisonous than the larvae of the leaf beetle, and many Bushman hunters prefer to use the larvae of the walking beetle to poison their bows and arrows."

"Even if you hit a large animal like a giraffe, you usually can't withstand it, but the animal that is shot is often able to escape 60 to 100 kilometers with injuries before it finally slows down and falls to the ground, which is a test of the hunter's tracking skills."
