The topic of skin color, being a minor interlude, quickly livened up the atmosphere in the live stream.
After a pause, Bi Fang steered the conversation back on track.
"Regarding the content of this live stream, I assu nobody is unclear, right?"
[We know, we know, Sahara Sahara!!]
[The Desert of Death!]
[The huge leper spot on Earth!]
As a super-desert comparable in size to the entirety of Huaxia, the Saharan fa is known to all.
It lies like a vast and unsightly scar prominently across the African land, becoming a renowned zone devoid of life.
So say that only after you have faced the trials of life and death in the Sahara Desert will you truly fall in love with the oasis, with life itself.
Even from this single piece of dialogue, one can glimpse the world's cruelty and wildness.
Challenging oneself, understanding the true essence of life—that's what Bi Fang had always been doing.
The audience had been eagerly anticipating this.
"Indeed, before crossing Nemo Point, I had made everything very clear, "This live stream is about crossing Nemo Point and then traversing the Sahara, with a total ti limit of one hundred and twenty days. Therefore, strictly speaking, our live stream has just passed one third."
Bi Fang pointed to the desert and Gobi in front of him.
"As you all can see, there is a desert before us, and you are not mistaken – Old Mugalen and I are currently located at the northernmost point of Burkina Faso, which is also the southernmost edge of the Sahara Desert."
"I have divided the desert into two levels; the first one is similar to the Gobi, which is harsh but still inhabited, with shrubs and even grass on the ground. The second level, as everyone imagines, is filled with sand dunes, a true uninhabited region."
"According to the information, the Sahara is actually a very broad concept, covering almost the entire north of Africa; all of this is the Sahara Desert. However, around its periter is the first level of desert, and only the center constitutes the true uninhabited area, which is the second level of desert."
"Our entry point this ti is Burkina Faso, and not long after entering from here, we will directly reach the core area of the Sahara."
"After that, our preliminary route plan is Burkina Faso → Mali → Algeria → Niger → Chad → Libya → Egypt, crossing the entire core of Sahara. Of course, in between—"
The Sahara Desert stretches about 4,800 kiloters from east to west, with its width varying between 1,300 and 1,900 kiloters in the north-south direction.
True crossing, naturally, is from east to west, not from south to north. We avoid the frivolous challenges – only to undertake the most difficult ones.
The route chosen by Bi Fang, looking at the map, is roughly from the lower left corner of the Sahara penetrating into the center and then across the entire east and west, with a route length of over five thousand kiloters.
"However, we have only eighty days left, and the ti fra is extrely tight. So, my plan is to capture a cal before we set off."
[666, Master Fang makes a move, astounding as always!]
[I rember Old Fang once said that cals are rare, they are protected animals. Can you just capture them like that?]
[Aweso, just finished watching Nemo Point, now cos a Sahara expedition, is this what happiness is?]
"This involves a conceptual issue, and since Mugalen just asked the sa question, I think it's necessary to do a bit of simple science popularization."
"Wild cals, feral cals, and dostic cals are actually three different things. The first one is a protected species, indeed rare; but the latter two aren't..."
As Bi Fang continued his explanation, the audience in front of the screen gradually got a clear concept.
Wild cals and dostic cals, if not for the absence of reproductive isolation, could even be considered two different species.
The genetic differences between the two are as high as 3%, even greater than the 0.5% to 1.4% difference between humans and gorillas!
Dostic cals that run away do indeed turn wild, but they cannot be called wild cals; the two had already diverged into two different species 800,000 years ago.
However, the so-called genetic differences being larger than those between humans and chimpanzees only indicate that the two species have long diverged, but this does not an that their kinship is more distant than that between humans and chimpanzees, as statistical calibers differ.
There is reproductive isolation between humans and chimpanzees, while there is no barrier between dostic cals and wild cals, no isolation whatsoever.
In areas where wild cals are found, the raising of dostic cals is not permitted, precisely to prevent genetic pollution of the wild cal population.
The wild cal population is small and protected, and Bi Fang had no opinion on this.
But as for feral cals, not only did Bi Fang have ideas, he had lots of them!
Compared with wild cals, feral dostic cals are undoubtedly much easier to ta and are more common in the Sahara Desert, not rare creatures at all, with their numbers possibly even reaching the hundreds of thousands.
Those dostic cals, estranged from their environnt, reproduce generation after generation in the desert, and although their wildness is significant, deep in their genes there are still things starkly different from wild cals.
Cals actually have very few natural enemies, their combat prowess is extrely high, and once they have a suitable environnt, they can breed prolifically.
Just look at Australia to understand, millions of feral cals have beco a plague.
Initially, Bi Fang truly didn't have the intention of capturing wild cals, but instead wanted to directly buy one, or choose the one he encountered in the Qaidam Desert nad Naren, a remarkable cal that survived a Naked Choke and still ca back to see you.
Cals that have already been tad, or even those that have had personal contact, are undoubtedly the best choice, minimizing many accidents and shortening the adaptation period.
But Bi Fang then thought that doing so would be too uninteresting.
Anyone can buy a cal, just pay so money, but how could he then have the nerve to say he crossed the Sahara on his own?
If he was going to do it, he wanted to do it thoroughly, truly accomplishing it all with his own abilities.
Up to now since his "debut," Bi Fang really hadn't used such large external forces, and he didn't want this ti to be an exception.
Compared to the many doubts that once existed within Bi Fang, the audience was rather unsurprised by his choice; on the contrary, they found it very Bi Fang.
A real man should be this way.
After joining in the excitent for a while, Mugalen, the porter, quickly left, and Bi Fang wandered alone with his backpack through this semi-desert area.
"Cals are called the ships of the desert because they are hardy and their humps store a large amount of fat, which can be broken down into water and energy, allowing them to go long periods without drinking or eating. However, this does not an they don't need water or food."
"Feral cals are equally scared of humans, therefore, regions that are sparsely populated but have extensive vegetation are their favorites. We'll search here, and we should quickly co across them."
