"Well, be careful, I'll go over and take a look first..."
Zhuang Rui knew that the length and breadth of this place was beyond the quicksand area, so he pretended to take a few steps, picked up the stone, stamped it on the sand, and said: "This is no longer quicksand, let's go a little further."
step……"
This is the edge of the quicksand area. It is still dangerous to be too close. Zhuang Rui walked forward for more than thirty meters before he stopped, took out a small flag and planted it on the ground, and said to Peng Fei: "Shout
Come here, they, I will explore the road ahead and let the camel team follow..."
Although Zhuang Rui clearly knew the terrain ahead, on the surface, there was no difference between this quicksand and ordinary yellow sand. If no one was exploring the road ahead, no one would dare to ride a camel arrogantly.
"Oh no, Professor Man fell into the quicksand..."
Just as Peng Fei turned around to greet everyone, Erdan's voice suddenly came over, making Zhuang Rui's heart tighten. Following the sound, Erdan, Mengzi and others were running towards Professor Man's place.
"Erdan, don't come close, damn, if I had known, Professor Man would have come here..."
Zhuang Rui shouted and ran over, one foot deep in the sand and the other shallow. When they reached the place where Professor Man fell into the quicksand, the people who were originally waiting on the sand dunes had already gathered around him.
"Teacher Man, is it okay? What do we need to do?"
Seeing that the quicksand only swallowed up the thighs of Professor Man's body and did not continue to sink, Zhuang Rui breathed a sigh of relief. After using his spiritual energy to look at the terrain on all sides, he couldn't help but feel dumbfounded.
It turned out that this piece of quicksand was in the shape of a gourd's mouth, with a slight protrusion. Professor Man happened to step on it, so he was unlucky.
"I'm fine, Xiaozhuang, please step back, and step back a little more..."
Compared to the panic of everyone around him, Professor Man, who fell into the quicksand, was calm and calm. There was no look of panic on his face. He just spoke in a low voice, as if he was afraid of causing shock and causing his body to sink.
"Professor Man, how...how did this come out?"
I heard Professor Man say before that he couldn't pull hard, and Zhuang Rui didn't know how to rescue him.
"It's okay, Xiaozhuang, help me find a one-meter hard board..."
Professor Man tried to keep his voice as soft as possible, and at the same time, he leaned forward slightly so that his abdomen was pressed against the sand. This is somewhat the same as in water. The larger the area in contact with the sand, the greater the buoyancy generated.
"Hard board? Teacher Man, do you think this thing is okay?"
Professor Man's request made Zhuang Rui scratch his head. He ran back to the camel and rummaged for a long time. He could only pull out a foldable aluminum alloy plate from under the tent and handed it to Professor Man.
After Professor Man took the alloy plate, he spread it on the sand surface very gently. The density of the alloy plate seemed to be lower than that of quicksand, and it did not sink when placed on the sand surface.
After laying the alloy plate, Professor Man opened his hands, leaned forward, and lay on the alloy plate. At the same time, his legs moved slightly left and right in the quicksand, allowing water and sand to penetrate as much as possible into the squeezed out vacuum area.
"Professor Man, you...how did you do this?"
Zhuang Rui and others stood around, watching Professor Man pull out his legs bit by bit as if by magic. Their eyes widened and they didn't understand how he did it.
"Let's talk about it after we come out..."
Professor Man shook his head gently. At this time, everyone saw his movements clearly. The yellow sand around Professor Man's body that originally contained moisture and seemed a bit sticky became obviously soft and scattered under Professor Man's movements.
Got up.
After more than half an hour, Professor Man finally got out of the quicksand and stood firm with the help of Zhuang Rui.
Although Professor Man acted very relaxed during this process, after standing on the ground, everyone could see that Professor Man's legs were shaking as if they were shaking, and his face was a little pale. It was obvious that he was hurt in his heart.
The impact is not small either.
"This...is coming out now?"
Erdan had seen the power of quicksand swallowing a camel. Now that Professor Man could get rid of the quicksand so easily, he felt a little psychologically unacceptable. He murmured to himself: "This... I wish I had known this, Da Mao"
He and Ermao don’t have to die..."
"You brat, get out of here, let alone the camel. It's just you who fell in. It'll be good if you can calm down..." Professor Man cheered up a little after taking a sip of water, and scolded Erdan with a smile.
Professor Man was a little scared when he thought about it. When he first fell into the quicksand, his legs seemed to be tied with a thousand kilograms of heavy weight, dragging his body down. If it were an inexperienced person, he would definitely struggle desperately.
Yes, the outcome is naturally self-evident.
"Teacher Man, can you get out of trouble just like you did just now?"
Mengzi was most concerned about this issue. He was begging for food in the desert. He might encounter quicksand at some point. If he could learn Professor Man's skill, it would be a life-saving skill.
Professor Man nodded and said: "Yes, the first thing you need to pay attention to is that when you fall into the quicksand, lean your body as far back as possible. If you fall in headfirst, the gods will not be able to save you...
The second point is to be like what I just did, don’t panic, move gently, and move your feet gently in the quicksand, so as to relieve the pressure on the body and at the same time let the sand slowly become loose..."
Although Professor Man was trapped in quicksand for the first time, he had quite a wealth of theoretical knowledge. Coupled with his previous practice, he could be called an expert on quicksand. Now he passed on some of his experiences to Mengzi and Er.
Egg.
Zhuang Rui waited until Professor Man and Mengzi finished talking, and then said: "Teacher Man, I have found the field there. Why don't you take a rest first, and let's go there in the afternoon..."
"Have you found the real thing? Let's go and have a look..."
Professor Man waved his hand. He had been working in the field all year round and his health was relatively good. After taking a short rest, he had already recovered.
Arriving at the place where Zhuang Rui had planted the flag, Professor Man squatted down and observed carefully for a while, then used a wooden stick to spread the quicksand surface two meters away from his body, and said: "Xiao Zhuang, come and see, this
You can't tell the difference on the sand, but if you pick the sand apart, there is still a slight difference..."
"Well, there is a slight difference. We all used a stupid method just now..."
Zhuang Rui took a closer look and saw that the yellow sand under the surface of the quicksand was different from the dry yellow sand on the ground. It looked a little bit moist. In fact, there was no need to use stones to explore the path, just use a stick.
After hearing Zhuang Rui's words, Professor Man shook his head and said, "It's early morning. If it's noon, it probably won't work..."
It almost never rains in the desert. After a few hours of scorching sunshine, even the yellow sand on the quicksand surface will become very dry. That's why Professor Man said this.
"Well, let's get on our way as soon as possible..."
I have been in the desert for several days, and now I am expected to find the ruins of the ancient temple. Zhuang Rui does not want to delay any longer, and immediately said: "Teacher Man, you sit on the camel and rest while I explore the road ahead..."
"Brother Zhuang, let me do it..."
Peng Fei snatched the wooden stick from Zhuang Rui's hand. This path exploration was a dangerous job. If he accidentally fell headfirst into the quicksand, even the gods would not be able to save him.
"Go, follow me..."
Zhuang Rui snatched the wooden stick away angrily. If Peng Fei was allowed to lead the way, he didn't know when he would be able to bypass this quicksand area.
After arguing for a while, Zhuang Rui finally used the threat of not bringing Peng Fei out in the future to win the job of exploring the path, and took the lead.
Walking in the desert was like stepping on a sponge, with one foot deep and one foot shallow. Fortunately, Zhuang Rui had the spiritual energy to recover his strength. It took him nearly five hours to get around this quicksand area.
"Look, there is an oasis ahead..."
Peng Fei had followed Zhuang Rui for a while, but he couldn't hold on anymore and got on the camel. He could see farther than Zhuang Rui on the camel, and he was the first to see a piece of vegetation in front of him.
The appearance of vegetation indicated that there was soil in the sand in front. Professor Man quickly greeted Zhuang Rui: "Xiao Zhuang, it's okay. Hurry up and get on the camel and take a rest..."
Dr. Ren and others had a little understanding of Zhuang Rui's physical fitness, but along the way, Professor Man and others were shocked to see that he could walk in the desert for five or six hours without stopping.
It almost exceeds the physiological limits of the human body.
"It's okay, Teacher Man, let's rest here tonight..."
Zhuang Rui approached the vegetation and discovered that there were several Populus euphratica trees growing around it, which humans call "live and survive for a thousand years, die and survive for a thousand years, and fall and remain immortal for a thousand years."
Tree.
It may be because of the existence of water sources. These poplar trees, which are not very tall, still have green on their branches and are not dead.
"Okay, I didn't expect that there would be such a desert oasis near the North Gobi. It seems that our work has not been done yet..."
As an important plant for desert control, Professor Man has a good understanding of Populus euphratica. After a cursory look, he judged the underground situation here and said: "There must be a water source within four meters here, and
It can be drunk directly..."
Relying on the protection of its root system, as long as the groundwater level is not lower than 4 meters, the Populus euphratica tree can live very comfortably. When the groundwater level drops to 6 to 9 meters, it can only put on a happy face and languish.
And if the groundwater level drops any further, the Populus euphratica trees will have no choice but to bid farewell to the world and live up to the saying that they will die but never fall down for a thousand years. Therefore, as long as you see rows of fresh or dried Populus euphratica trees in the desert, you will see them.
It can be judged that there was once a water source here.
