Under the moonlight, the earth is only black and white.
The fine gravel reflects the moonlight, and the desert surface is slightly white, with only a black spot suddenly appearing on the silver carpet.
The huge camel bent its long neck and lowered its head to drink water. The dark water surface had layers of bright and dark ripples.
Bi Fang squatted on one knee, dipped his hand into some water, put it in front of his nose and smelled it, flicked his fingers to shake off the water stains, and wiped it dry on the sand.
"There is no peculiar smell, it should be a normal water source."
Today is not a full moon, and visibility is limited. Bi Fang cannot judge the purity of the water source by looking at it, and can only roughly judge it by smell.
"All oasis water sources in the desert are living water. Dead water cannot exist here for a long time. It has the highest water vapor evaporation rate in the world. A 100 ml glass of water can evaporate in a few minutes in the most ordinary glass.
It has to be clean."
"However, even running water cannot be taken lightly. There are a huge number of wild camels in the desert, and they often defecate in water sources."
"Especially on some fixed routes, where hundreds of camels drink and rest every day, they will even directly dye the water black."
"It's natural for a camel to drink such water, but humans don't have such a constitution, and they can't withstand such water."
"There is no odor, and dangerous creatures nearby have been eliminated. It is most likely a normal water source."
【Okay, we found water!】
[Fang Shenya only looks at Yile, but if he really wants to find water, he still has to look at me, Alpha]
【Are you polite?】
Bi Fang stood up and used a tree stick to explore the bushes to avoid any poisonous insects, snakes and scorpions hidden inside. Then he began to break dead branches and prepare to light a fire and boil water.
This oasis is very long and narrow, looking like a banana from a high altitude. Its total area is about the size of a football field. It is neither too small nor too big. It is surrounded by a narrow green belt less than three meters wide.
Bi Fang went around half a circle to collect enough firewood.
These dead plants have lost their ability to draw water. Compared with the humid climate of the rainforest, as long as they stay in the desert for one day, they will completely lose their body moisture and become firewood that is easily ignited. This is one of the few in the desert.
One of the conveniences.
Bi Fang took out two pieces of flint from his backpack and rubbed them with one hand. A few sparks floated on the dry branches. After repeated several times, a circle of orange light soon ignited in the darkness.
The flames dispelled the cold and darkness, and Bifang picked out a thicker branch and carried it to the waterhole.
The water reflected the firelight clearly, but the color of the water was still invisible.
Bi Fang gave up the idea and continued to boil water.
"If you don't find a direct source of water in the desert, but only find green plants, you can also put plastic bags directly on the green plants and wait for the transpiration during the day, coupled with the distillation of the temperature difference between day and night, to get clean
water source.”
"In ancient times, it was said that grain could not be transported a thousand miles during a war. This meant that the grain transported a thousand miles was no longer enough for the mules, horses and escorts."
"It makes no sense to carry 50 pounds and sweat 40 pounds. You should balance the weight appropriately according to your physiological condition and distance. Generally speaking, 4000 ml is enough in the desert."
"But, I have Alpha. It won't be a problem to triple the amount of water on my back. What limits us is the container."
"Filling water requires relatively high requirements for containers, and they must be properly stored. The best thing is actually the stomach bags of animals, or if you are more skilled, you can use their skins."
Bi Fang rummaged through his backpack and took out a few dead rattlesnakes, which he had encountered on the road these days. Some had been eaten, leaving only the snake skin and stomach. At this time, they had become
Excellent water storage material.
"Although rattlesnakes are not large in size, their stomachs are extremely well expandable. One snake can hold two liters of water without any problem, and it is like a balloon. As long as it is tied with a knot at the end, it will not leak.
"
Bi Fang put the snakes on his arms one by one, took them to the pond, and started cleaning and making them.
With four snakes and a kettle, you can carry nearly 10,000 ml of water. Save some water and still be able to hold on for a week.
"It's better not to sleep too close to water sources at night, as it's easy to run into other animals. We can come back tomorrow."
After getting some water, Bi Fang did not choose to stay here for the whole night. Instead, he led Alpha, who was full of water, towards the southwest. He also dug a hole without looking for shelter and spent the night carefully.
.
Early the next morning, Bi Fang came to the water pool again, continued to boil water, looked at the surrounding environment, even watered the water and took a bath, washed his clothes, washed away the heat all over his body, and then walked near the oasis.
I searched for suitable plants and weaved soft baskets.
Alpha was nibbling on buds in the oasis, moving his mouth from side to side to make up for the losses of the past few days, and even rarely peed. After repeated absorption, it was almost as thick as pus, although it had a strong taste.
But it still surprised many viewers.
[Speaking of which, is Fang Shen pretending too much? He feels like he is going to explode.]
[This creamy yellow color reminds me of something bad (dog head)]
[Whatever comes to your mind, say it boldly!]
【Too avant-garde】
[We old-fashioned people can’t see this]
【Are you really not going to explode? 】
Baskets made of woven branches were hung on both sides of the camel. Bifang put the bulging snake stomach bag into it, like big milky white balloons filled with water. You can clearly see the water flowing inside through the surface.
Water makes people worry about whether it is filled with too much water.
"Don't worry, the snake's stomach band is very expandable, and I specially woven a soft basket so it won't break easily."
Bi Fang held the baskets on both sides of the camel, which were woven with long leaves. They were more like hollow bags than frames, holding the water bag tightly.
After doing this, Bi Fang looked back at Alpha and found that it was still grazing in the bushes.
【Absolutely hungry】
[By the way, Alpha hasn’t eaten for a long time (dog head)]
[I ate some. In fact, I didn’t encounter any plants at all. Didn’t I encounter two trees last time? It’s just that I didn’t feel full.]
[The poor child’s hump is quite deflated]
An adult healthy camel can survive without eating or drinking for 15-30 days if it is well fed and drunk.
Under normal circumstances, a camel can eat about 13 kilograms of dry food and drink about 10 liters of water in one meal.
In extreme circumstances, such as coming back from the desert, you can eat at least 30 kilograms of food and drink up to 120 liters of water at one time.
The food and water they eat and drink every day far exceed their body needs. This is actually a reserve, and the sign is that the hump is full and upright.
Eating more and drinking more lays the foundation for the camel's ability to withstand hunger and thirst in the future.
After following Bifang for so long, as the audience said, the hump is indeed not as bulging as it was at the beginning. It looks a little weak and the peaks are a little soft. Of course, it may be because of sitting for a long time.
The fat in the hump also needs to be replenished, so Bi Fang decided to wait for a day, or even two days if necessary, before setting off tomorrow to get Alpha back to its peak condition as much as possible.
"We still have plenty of time, let's see if there is any food to collect next."
There are several doom palm trees in the oasis, and you may also be able to find some fruits.
You can also look for fish in the pool to make further supplements.
"Fish cannot survive without water, and water happens to be the most scarce resource in the desert. Therefore, many people may think that there cannot be fish in the desert."
"But deserts are not completely lifeless. There are usually oases in the desert, and there may be fish in the water of the oasis, especially in deserts with many underground rivers. For example, there are crucian carp and grass carp in the oasis in the Taklimakan Desert in my country."
"In addition to oases, there are also underground rivers, lakes and caves in the desert."
[Oasis, lake, underground river, aren’t these the same thing (trembling)]
[Bold! Presumptuous! Are you questioning Fang Shen!, Dog head saves his life]
【Our god cannot be wrong!】
"There is still a difference." Bi Fang rubbed his head and laughed, "Generally, lakes in the desert are oases, but there are exceptions."
"There is a desert covering an area of 1,500 square kilometers in Niulaniang State in northeastern Pakistan, which is the famous Thousand Lakes Desert."
"Brazil mainly has a tropical rainforest climate. Everyone should know this, so deserts are indeed relatively rare, and the formation of this desert actually has a lot to do with the tropical rainforest climate."
"Because Brazil has too much rainfall, its two main rivers often flood seasonally. The flooded river water carries a large amount of sediment and pours into the Atlantic Ocean, forming a large number of yellow sand dunes at the estuary. These yellow sand dunes are due to
The influence of trade winds blowing from the sea was blown inland, forming deserts."
[Good guy, things must be reversed when they reach their extremes]
[Weird geographical knowledge has been added]
Bi Fang broke off a branch from the tree and made fishing lines and hooks.
"After the desert was formed, because the average annual precipitation here was as high as 1,600 millimeters, once the rainy season came, large and small lakes would form in the desert, hence the name Qianhu Desert, but it is not an oasis.
Because this lake is not stable, but the ecology of the oasis is stable."
"The dry lake desert is the same as the river, so there are a lot of fish, and it has the achievement of having the most fish desert in the world."
Bi Fang processed a small section of elastic branch into a hook structure, stuffed it into a small section of pipe, tied it to the fishing line, and threw it into the lake.
"The second is the underground river. There are various forms of underground rivers in the desert. Some of them rain a lot, but they cannot be stored. They enter the ground, and some dry up completely. However, due to the large temperature difference between day and night in the desert, the water vapor in the air will evaporate at night.
It is saturated and condenses through the desert surface into the ground, and after years of accumulation, flowing groundwater will form underground in some desert areas."
"The desert underground river has no entrance, but it has an outlet and is connected to other water systems, so fish from other water systems will enter it."
"However, since there is no light after entering the underground river, these fish often degenerate their eyes and become blind fish."
"The Tuagre people in the Sahara Desert live completely in the desert. As humans, they naturally need water and food. The main source of water is the underground river, and the food is the fish in the underground river."
"Living in the desert for a long time, the Tuagre people can accurately find underground rivers. The next step is to dig them. When the water comes out, they will put insects on the hooks to fish."
【Another miraculous race】
[There are Sherpas in Everest, who are the diving people, and the Maasai people, we are all human beings, why are they so stupid]
[But Fang Shen is more awesome than all of them!]
[I understand, Fang Shen is the ultimate creature!
】
[I have long suspected that Lao Fang is not a human being (funny)]
"Finally, there are caves. In addition to underground rivers, oases and lakes, there are also naturally formed caves in the desert. Some of these caves have water, and there are also fish in these caves with water."
"Death Valley in the Ugly Country is an arid and uninhabited area. There is a 130-meter-deep cave in the Mojave Desert. Fish were found in it. The body length of these fish is less than 5 centimeters, and the number is about
300, and later scientists named it the Devil Killifish."
"There is nothing much to say about the oasis, because the oasis itself is a complete small ecology, with invertebrates and aquatic plants in the water."
"It's just that most of the fish in the above-mentioned terrain are not large, because in most of the above environments, the food abundance is very poor and cannot support large fish, and these small fish rely on their smaller body size to
It has low energy requirements and survives tenaciously.”
"Because of this, we don't need a very good fishing rod, a branch is enough."
While talking, Bifang pulled up the branch, and a small fish no bigger than a palm hung on it, flapping its tail continuously.
"Tilapia, the most common fish in the Sahara Desert, seems to have underground areas extending in all directions."
[Hiss, there are really fish! 】
[Fishing in the desert, you have a good skill]
【It's you】
【Would fish taste better in the desert?】
[No, it will be more expensive]
Bi Fang picked it off, put it into Lou Kuang, hung the fruit on the fishhook, and continued to throw it into the pool.
Waiting for the afternoon, Alpha stopped eating, and Bi Fang also gained a lot and had a grilled fish dinner at night.
The next day, Alpha continued to eat, chewing monotonously with his big mouth, as if he would never get tired, like a ruthless eating machine.
Bi Fang touched Alpha's hump and found that most of it had recovered, which showed that it had almost stopped.
After filling the kettle with water for the last time, Bifang took away Alpha who was still eating, got on his back, and continued moving forward.
Underfoot is the vast desert, and above the head is the vast blue sky without a trace of color. The sky and the vast desert form a line at the far edge.
Mali has become the background. Maybe tomorrow, or the day after tomorrow, they will reach the next country.
