With all their might, the two climbed the hill and stood on the ridgeline of the hill to look at the rolling hills ahead.

From this height, a green spot could be clearly seen in the distance, but there were still seven or eight hills from the hill, which meant that they would not have been able to reach it today anyway.

Well, they can only set a small goal now and get as close to the destination as possible.

"Look, there's a green area over there, probably where the underground river flows, and that's where we're headed. ”

"Look at the sky, it's about five o'clock in the afternoon, and we're going to try to get halfway while it's not very hot, so that tomorrow morning we'll be able to walk to that green area without having to go under the scorching sun. ”

"Weiwei, we go down the mountain, go up and down the mountain on this kind of slope full of gravel, especially pay attention to safety, we must not go straight down, we must take the zigzag diagonal line, go out, safety first. ”

"People look at me, I first have to find a point under the diagonal, preferably without any obstacles between this point and me, and then walk towards this point, a little faster, but when you get to this point, you have to slow down, stop at this point, and then find the next point. ”

"This method is not only suitable here, but also for some steep slopes, as well as some spillways with no vegetation, and of course, it is best not to use the spillway unless absolutely necessary. ”

"This method has a name, which is called setting a small goal first, for example, making him 100 million first, hehe, just kidding. However, the most taboo thing when going down the mountain is to rush down, which can't be braked. Also, the biggest advantage of walking diagonally is that the slope is slower, so that the pressure on the ankles and knees is much less and much safer. ”

After descending the mountain, the two walked along the valley to their destination, and Liu Danqing continued to introduce the experience.

"Now, we have to continue on our journey, and in order to save time and energy, and to be safer, we will try to walk through the valley as much as possible. ”

"The valley naturally has the characteristics of the valley, that is, it is zigzag, so we have to look for the direction, just on the top of the mountain, I have found two coordinate points, both are relatively high ridges. ”

"The first coordinate point is the somewhat sharp summit, which is very, very rare in this part of the hills, and there is no semicolon in our vicinity, and the second coordinate point, on the contrary, is a very flat ridge, and the green space is in the gap in front of the very flat ridge, and that is our goal. ”

"When we get closer to the green space, we climb up a high ground again to determine the greenest part of the green space, and the darker the green, the more likely there is water. ”

After turning a corner, Xiao Weiwei pointed to a depression in front of her left and asked, "Qingqing, there is a depression there, the terrain is very low, will there be a water source?"

Liu Danqing looked at it, shook his head, and said: "There is no trace of greenery there, nor a trace of wetness, and it is unlikely that there will be groundwater." If there is water in the depression, even if there are no plants growing at the bottom, there will be plants such as camel thorns and saxon trees growing on the surrounding slopes. ”

"In the desert, plants are very tenacious, and with a little bit of water, even if it's not moisture, just moisture, they can grow very well. ”

Along the way, Liu Danqing began to collect the plants that passed by.

The fruit knife that Liu Danqing despised once again played a huge role.

The plants in the desert, because the stalks are relatively flexible because of little water, and the root system is very developed, without this small fruit knife, Liu Danqing doesn't know how much effort to spend.

Liu Danqing explained while using his mobile phone or yellow or green weeds:

"Now I'm collecting these plants so that I can sleep at night with some under my body and some under my clothes, so I can forget about thorny plants like camel thorns. ”

"At night in the Gobi, the temperature will be twenty or thirty degrees lower than during the day, and it is estimated that the minimum temperature tonight should be about ten degrees, and we don't have enough time and fuel to build a bonfire to keep warm, so we can only use this most primitive method to survive the night. ”

"In China, from ancient times until a period of hard time after liberation, many people used this method to improve the quality of sleep in winter, and they would spread a thick layer of straw on the bed board to make their bed soft and warm. ”

"In the Northeast, there used to be a saying that 'there are three treasures in the Northeast, ginseng, mink, and ula grass', and people would beat the ula grass with a wooden stick and stuff it into their shoes and clothes to help keep themselves warm. ”

This area is close to the desert plains, so there are very few plants, and even if you find a clump of grass, it is very small, and if you cut it all, it is only a handful.

But the grass is too little to hold the many times, and soon, the hands of the two are inconvenient to hold, Liu Danqing simply untied his short-sleeved shirt tied to his waist, rolled it diagonally into a long strip, and bundled the straw.

It wasn't until the sky got dark that Liu Danqing and Xiao Weiwei found a depression in the rock and prepared to camp.

By this time, they had already collected one bundle of grass, plus two handfuls.

Putting the lunch box on the ground and pressing it with a few small stones, Liu Danqing began to clean up the broken stones and small stones on the ground.

"We can only camp here at night, but at least we don't have to worry about the rain here, I should say that we don't have the luxury of expecting it to rain here, the whole of September, the rain in the Gobi does not exceed 30 milliliters, often not a drop of rain. ”

"Although in the Great Gobi, the probability of rainfall in the hilly area is much higher than that in the plain area because of the topography, it is only compared to the desert plain we have just passed, and here is located on the edge of the hilly area, the probability of rainfall is even lower. ”

Xiao Weiwei saw Liu Danqing start to clean up the ground, and also came over to help, and asked while cleaning up: "Qingqing, let's sleep here at night?"

Liu Danqing nodded and replied: "Yes, you see that this depression has its back to the plain and faces the hilly area, that is, it is sitting south and facing north, and it is summer, and the southeast wind blows, so it can help us block the night wind." ”

"In this hellish place, there are not even a few grasses, and there is no large grass nearby, which means that mosquitoes can't survive, so you don't have to worry about mosquitoes at night, so you can sleep at ease. ”

Then in the last trace of night, Liu Danqing spread the green grass on the ground, took off his outdoor clothes, put on his shirt, put on his outdoor clothes, and then picked up the withered yellow weeds and stuffed them into his clothes, especially his stomach.

"Weiwei, you do the same as I do, stuff this dead grass into your clothes, especially on your stomach. In the wild, the stomach is the most important place to keep warm, and if the stomach catches a cold, it will cause diarrhea, and diarrhea is the most likely to make people dehydrated. ”

After settling down, the two took out their phones and began to interact.

At this moment, Xiao Weiwei finally began to complain about the barrenness here, and the barren land is not to talk about.

Now, she doesn't even have the spirit to sing, and she can't sing well if she wants to, her mouth is very dry, but she is reluctant to drink water.
