Chapter 820 Mural

It seemed that the captain left after a brief exchange just to comfort Bifang.

Then the air fell into silence.

Until eight o'clock in the evening, Bifang did not see him again.

In the office, the brand new ceiling fan worked hard, but it could not reduce the heat.

Sitting on the chair, Bifang glanced at the police in the police station, and his index finger could not help but tap the armrest of the chair.

Those who read newspapers read newspapers, those who drank tea drank tea, and those who chatted chatted, completely forgetting about him, the "spy".

Helplessly, Bifang had to hold a middle-aged police officer who was about to refill his cup. This was also one of the police who brought him here.

"How long will it take to confirm my identity?"

"Uh, what?"

"I said, how long will it take to confirm my identity, and then let me go."

Bifang wondered if his Arabic was not standard enough, but he thought it was unlikely, after all, it was a system product.

The middle-aged police officer paused: "Uh, tomorrow, tomorrow will be fine."

[Damn, I have a bad feeling]

[Will it take so long?]

[After all, they are spies, so they should be more cautious, right? Maybe]

[I don't feel their caution at all? ]

Seeing the barrage, Bifang also had the same worry in his heart. He frowned slightly, but it was hard to say anything.

"Tomorrow?"

One day is still within his acceptable range.

Let's wait and see.

The next day.

"How long will it take?"

"Well, we are contacting China, but we haven't found the phone number yet..."

"If it's just a phone call, I know roughly."

Bifang sighed.

...

No one could have thought of it.

Bifang was found by the police at noon and came to the police station in the afternoon. The result was not obtained until the morning of the third day. It was already the fourth day when he was finally released.

In the meantime, he was questioned by multiple groups of police officers, and his passport was taken away by the police for verification.

But no one knows what the efficiency was in the meantime.

Finally, the netizens in the live broadcast room were reliable and informed the Modu Contact Center. The staff of the Contact Center immediately contacted the Chinese Embassy in Algeria and asked them for help.

Bifang successfully escaped with the help of the Chinese Embassy.

Looking back, the process was exhausting.

Bifang usually rarely talked about the problems of other countries, but this time he was really exhausted, especially the slowness and low efficiency of Algeria, which almost drove him crazy.

The so-called "tomorrow" in his mouth was never the real tomorrow, but "someday in the future".

If it weren't for the embassy's help, Bifang suspected that he might not be able to get out for four or five days in a row. Fortunately, he had some food reserves, otherwise he might really starve to death in the police station.

"Finally out."

After thanking the embassy again, Bifang walked out of the police station and felt that the air was much fresher, full of the smell of freedom.

[Fang Shen never thought that the thing that delayed him the most after he set out was actually being suspected of being a spy. Hahahaha, I almost died of laughter]

[Brother, you talked so much in one breath, aren't you tired?]

[We've been waiting for several days, let's set off quickly! ]

"That's right, we've wasted more than three days, we have to continue on our way."

"And this is also a valuable experience, isn't it? When you go out to travel in the future, especially to some special countries, it's better to be fully prepared."

Being mistaken for a spy is just a small episode in the journey.

After settling the matter, Bifang led Alpha out of the town and continued along the original route.

"The next journey is still a long way to go."

Twenty days later.

After leaving Algeria, Bifang crossed Niger, saw the magnificence and beauty of the Niger River, crossed a half-grassland and half-desert area, and now came to Libya.

With such a large span, the audience finally understood what kind of scene the rock desert that Bifang mentioned at the beginning was.

The surroundings are no longer vast sand dunes, but towering rock walls, and huge rocks that have become bizarre due to wind erosion are everywhere, as strange as if on an alien planet.

The wide canyon is on the right side of Bifang, and on his left side is a bright red train running along the track.

The train leading to the canyon is painted red, and this color turns into a curve that wanders and twists between the yellow Gobi and the white desert, so this train has a beautiful name-the Red Lizard Express.

After eating sand for nearly a month, it was hard to see some modern technology, which made the audience in the live broadcast room feel a long-lost popularity.

Watching the train leave, Bifang moved along the track.

After passing through several tunnels, the surrounding scenery suddenly became weird. It was clearly a copy of the Colorado Grand Canyon with thousands of feet of walls in the African desert.

There is also a stream in the valley. As the river flows, the mountains near and far become lively.

Originally, I thought that green life can be seen where there is water, but this rule obviously does not apply to streams with extremely high salt content.

It is its flow that has aggravated the continuous deterioration of the local sand quality and made the already barren land even more desolate.

Bifang rode a camel to the top of the canyon. At this time, the canyon was like an open door, and the sunlight poured in from the cracks of the door, reflecting the streams in the canyon as if reflecting the light of mercury, making people suddenly think that there were treasures there.

[This canyon is so fucking big]

[Do you want to go in?]

[To be honest, I want to go in and take a look]

Bifang nodded. Even if the audience didn't say anything, he would not miss the opportunity to enter the canyon.

He drove Alpha down the rock step by step.

At first, Alpha was a little scared and reluctant. In the end, Bifang had no choice but to come down and lead it down little by little.

Bifang found a clean pool along the stream, reached in and tasted some, and was surprised to find that the water in the pool was fresh water.

"It shouldn't be a water system. This pool is groundwater, and the stream just now should come from somewhere else."

After finding the water source, Bifang put the kettle deep into it and watched the clear fresh water pouring into it. Before he drank it, he felt a little cool in the heat.

It is now mid-July, and standing under the sun in the Sahara can make people crazy. Even Alpha is rubbing his hooves and seems a little restless.

Bifang had no choice but to take it to a cool place to rest around ten o'clock.

After searching for nearly an hour, Bifang finally found an excellent shelter several kilometers away from the oasis.

It was a huge cave. Just standing at the entrance of the cave, one could feel a cool feeling that was very different from the outside world.

And near this cave, there are other caves, twos and threes, adding up to about a dozen.

Such a huge cave, combined with the quiet and unfamiliar environment, can't help but make people a little scared.

[Hiss, what a big hole]

[Is this naturally formed? It doesn't look like it]

[Dug by people, it seems to have been abandoned? ]

[I see there seem to be other caves next to it. This should be a human settlement, right? ]

[Will there be any monsters in it? ]

[Lizard people, right?]

[My evaluation is, watch less horror movies]

After entering it, Bifang scanned the circle to see if there were any snake ants hiding, and then pulled Alpha into it. Facing the audience's doubts, he didn't find it strange.

"I don't know if you have watched Star Wars. The planet Tatooine in the movie is desolate, cold, and barren. Skywalker was born and grew up on that planet."

"And the place where Skywalker lives in the Star Wars movie has a prototype. In reality, it is the home of the indigenous Berbers in North Africa. They have lived here for thousands of years and have developed a complete living system based on local conditions."

"There is also an underground village called Matmata near Tatooine. There are about 500 large holes like meteorite craters on the ground."

"There are guardrails around the cave entrance. That is the Berbers. It takes four people two years to dig a large cave. The diameter of the cave entrance is about 10 meters, and then the living quarters such as bedrooms and kitchens are dug deep into the cave wall. Usually, a large cave can accommodate five or six families. Such a building structure allows the desert area to have a cool and comfortable experience. "

"Although it is not clear whether this one in front of us was also built by the Berbers, and why it was abandoned, the principle is the same. I think it is also a proof that humans lived here in ancient times."

Bifang touched the rock wall, even the vertical rock wall was covered with a thin layer of dust.

The dust on the ground is almost several millimeters thick, and a deep footprint can be left with one foot.

Obviously, no one has visited it for a long time before Bifang visited today.

The cave is very deep inside, and Bifang also saw some murals on the wall. The strokes are very simple, just like children's stick drawings.

Due to the long time, it is covered with a layer of dust, and the picture is a little blurry, but the general content can still be seen.

The murals show herds of cattle and sheep, and some hunting scenes. The pigments are basically red and white.

After looking at a few paintings, Bifang was a little surprised.

"This has existed at least four thousand years ago."

[Fuck, so long? ]

[Really?]

[Where is the basis? ]

[Textual research experts are online]

Bifang shook his head: "I don't know much about archaeology. I just made some judgments based on the content of the murals, which may not be accurate."

"Look at the content of the murals above. There are not only cattle and sheep, no elephants, no camels. According to the climate change in the Sahara that I mentioned before, it can correspond."

[Ah, what changes]

[Did I miss class again?]

[I didn't miss class, but I have forgotten everything (dog head)]

Bifang laughed and didn't care. Instead, he explained the climate change process of the Sahara again, and then explained the possible stages of the murals again.

"Based on the rock paintings found in the Sahara Desert and the climate changes in the Sahara, we can actually divide these different rock paintings into several stages."

"The first is the buffalo period, which lasted from about 35,000 years ago to about 8000 BC."

"The rock paintings of this period were painted on the rocks with pigments mixed with the milk of some animals that are now extinct in the area."

"Including buffalo, elephant, hippopotamus and rhinoceros, the characters in the paintings use sticks, axes, bows and arrows and use sticks to hit prey, but usually without javelins, they often wear round helmets."

"These rock paintings are mainly distributed in southeastern Algeria, as well as Chad and Libya, which is where we are now."

"The second is the cattle period, which lasted from about 7500 BC to about 4000 BC.

"During this period, local residents began to lead a nomadic life, herding cattle and sheep. Pottery and Neolithic stone axes, millstones and arrowheads that had been polished and processed were found, as well as some bows and arrows for hunting."

"The animals for grazing were introduced from Asia. Later, some village remains that could gather more people and livestock were also found."

"The third is the horse period, which was about 3000 BC to 700 BC."

"During this period, there are signs that horses, camels and cows were introduced to the local area, and large-scale agriculture was engaged in."

"It was probably around 1220 BC that the Phoenicians learned to use and forge iron tools. The Phoenicians established a large empire alliance spanning the entire Sahara to Egypt."

"If you want to record it with murals, it is impossible that there is no such scene, but this time point is quite close, and it is generally not expressed in murals."

Hearing this, the audience in front of the screen has basically understood.

The content of the murals is neither as prosperous as before the climate change, nor as prosperous after the change, but in an intermediate state.

Then the time point described is most likely in the middle period.

[So have the people who originally lived here left? ]

[They may have been killed by people from other tribes (dog head)]

"Maybe."

Bifang did not give a definite answer.

Since 2500 BC, the Sahara has become a large desert like the current state, becoming an insurmountable obstacle for humans at that time, with only a few residents in the oasis.

The only exception is the Nile Valley. Due to sufficient water sources, it has become an area where plants grow luxuriantly and has become one of the birthplaces of human civilization.

Before all this happened completely, naturally many people made their own choices.

Faced with the deterioration of the environment, humans will never sit idly by.

【By the way, has Fang Shen discovered something incredible again?】

"Not really. There are actually a lot of murals in the Sahara Desert."

"During the last ice age, the Sahara was not a desert yet. The climate was similar to that of East Africa. The number of murals left at that time was extremely large."

"Archaeologists have discovered about 30,000 ancient rock paintings in the desert, about half of which are on the En-Ajer Plateau in southern Algeria, depicting animals in the river, such as crocodiles."

"There are still many that have not been discovered. What we see in front of us may be just one of them."

"It may not even be one of them."
