Deserts, especially areas of the desert where water scarcity is severe, have always been inaccessible to human footprints.

"There's grass in front again, I'll take a look......"

"Hey, this is a grass endemic to the Rub al-Hali Desert, called Nashi."

Jia Long stepped forward and plucked the short-stemmed blade of grass.

After some observation, she picked up the white part of the rhizome and cut it off, then patted the white stem as much soil as possible, and threw it into her mouth.

"It's sweet, and it's a little watery, but it's mixed with the smell of sand, and it's generally unsatisfactory."

"This grass, called Naxi, grows abundantly in the Rub al-Khali Desert and is one of the staple foods of many creatures, including oryx."

Jia Long explained while chewing.

In fact, there is not much water in grasses, and it can only be regarded as better than nothing.

There is more green on the ground, and you can see that there will be more vegetation ahead.

"You might think that the desert must be like the one you just saw, there is nothing. But in reality, deserts are not all extreme terrain of sand dunes. ”

"Even in the desert, the dune area we just walked through is one of the most extreme areas."

"Isn't it surprising that in the desert terrain other than the dunes, there are not only plants, but even some unique vegetables or fruits that can only be found in the desert?"

"Of course, it's impossible to see the foliage of a primeval forest here."

Jia Long said so, but in the desert area she slowly walked into, there were still not too many plants.

In the distance, it looks green, but when it gets closer, it becomes sparse, one here, one there.

Ordinary plants are not of much help to Jia Long now, and at the moment she needs to replenish a relatively large amount of water, and ordinary plants cannot satisfy her.

Her eyes kept looking around.

Soon, Jia Long's expression was happy.

Because she found a plant that could help her solve her current dilemma.

"Look, you all know that plant, right?"

With Jia Long's surprise words, the drone camera turned to the direction she said.

When they see the plant in the footage, everyone can name it.

"Cactus?"

"There's actually a cactus, and it's so big."

That's right, the direction Jia Long was looking at was a huge cactus.

It is more than a meter tall and has several stems.

Jia Long walked towards the cactus, which was more than a meter tall and had many thick stems.

"Cactus, also known as the desert plant room, is a plant of the cactus family. Characterized by the fact that it is dormant during the dry season, this plant has evolved to survive in arid areas. ”

"In order to prevent water escape, their stems become wider, and the leaves become needle-shaped, with occasional downy white hairs on them, which is evolved to minimize water loss and reduce the damage of sunlight to the plants."

"And cacti also have ribs, so that they can shrink the plant stem to a certain extent, when the plant body has enough water, the branches and stems are elongated, try to accommodate more water, when the water is not much, the plant body shrinks inward, reducing water loss."

While Jia Long said so much, he had already observed the cactus in front of him.

"Luckily, this cactus is supposed to store a lot of water."

"As long as you cut off a part of its stems, you can get water, and if you look at its thick stems, you can see that it must be hiding a lot of water."

Jia Long licked his lips, which had been thirsty for a long time.

Then she didn't say much, reached behind her belt, and pulled out the small straight knife that had been exchanged from the system.

Pulling out the scabbard, Jia Long lit up the sharp knife face.

Blame.

With a knife in hand, he simply cut off a cactus plant stem about 256 centimeters long.

After it fell to the sand, it quickly gurgled out in the shape of clear water.

Jia Long hurriedly used the blade to shave the surface of the spikes on this stalk, and then raised his bare hand to pick up the spine stem.

Looking at the incision that was still dripping, Jia Long hurriedly leaned the corner of his mouth to the broken section, and then drank the dripping juice.

Not to mention, such a small section can drip a lot of water.

After drinking about a small sip, the water in it stopped dripping.

"The taste is very strange, and many kinds of cacti will actually contain toxins such as alkaloids, and I generally can't tell the difference, so I don't recommend everyone to drink the water in the cactus casually."

"But the one I drink is non-toxic, it's called cactus, and it contains a lot of trace elements. Even recently discovered, it also has the effect of beauty, beauty, and dealing with diabetes, which can be said to have a lot of effects, if you want to try, you can find edible cactus to try. ”

After Jia Long finished speaking, he picked up this truncated cactus again, such a large piece, and the weight was not very light.

After looking left and right for a full five minutes, I found that there were several huge protruding stones on a back slope a hundred meters away.

"Let's go that way, there are some rocks that don't fit into the shelter where we are temporarily resting."

It was past ten o'clock, and the sun above me was getting extremely hot.

Jia Long even felt that he couldn't secrete his sweat, because it was dried as soon as it came out.

"You don't feel it, the hottest time in the desert is coming."

"Now my body temperature is definitely more than 356 degrees, and it may exceed 40 degrees later, and in this high temperature, I have begun to feel that my body is showing signs of heat damage."

"Although I haven't had heat stroke yet, I have a slight cramp in my hands and feet, which is caused by the loss of water from my body and the removal of a lot of salt."

"These signals are a warning from our body, and if we don't deal with it, it will become a big life-threatening problem, so I have to find a cool place to rest as soon as possible, otherwise what awaits me will only be heat stroke like Nanyang Island. Of course, this time there are no such good conditions as Nanyang Island, if I suffer from heat stroke, I am alone in the desert, I can only call the heavens should not be, the earth is not spiritual, and I am lonely and waiting for death. ”

Jia Long said, quickly rushing to the places that looked like big rocks.

Sure enough, in this place, there was a sunken terrain, which was shaded by the high ground, and the size of it could accommodate two or three people.

Jia Long looked at the sky, and estimated that even if it was noon, it would not be directly exposed to the sun, so he was satisfied with the cactus plant stem and climbed into it.

The drone seems to be not afraid of the high temperature and follows this place slowly.

"It's nice to be able to find a relatively shady place like this in the desert, at least we can avoid the sun as much as possible, and even at noon, it should be able to block out a certain amount of light for us to have a good rest."

"And our lunch at noon has also fallen, everyone look at ......" please Baidu "throw the book network" Thank you for your support!
