In fact, the structure of this channel is very simple, it is just a U-shaped tube. This side of the pipe is full of this special sand, and the other one on the opposite side is only partially sandy, and this part can achieve its function as long as it is higher than the arc of the U-shaped bend.

"It's not necessarily comfortable to jump directly." I stepped on the sand on the ground, thinking to myself that if all I touched was solid, it wouldn't feel too comfortable.

Neither of them replied, but I saw them look at each other and turned to look directly at me. Seeing that this was not right, I immediately took a few steps back. "Damn, what do you want."

After speaking, I saw the fat man wave his hand and gesture his body: "This time you have to hit the head, we don't know how wide it is below, you are the thinnest here, do you want to sacrifice it?" ”

The fat man does have to take care of this problem, but looking at the old generation, he is not much different from me, but just glanced at him, and saw him make a few gestures to show his muscles, he made such a comparison, the width of his shoulders is really much wider than mine, in fact, the actual reason is because the muscles on his shoulders are too developed.

I glanced back at the sand pit on the ground: "If it's okay for me to go down, then how can I inform you, you can't shout down here." As soon as he finished speaking, the fat man took out a coil of rope the thickness of a wire from his waist bag.

Then we cleaned the ground of the ordinary sand, and immediately found that there was indeed a round hole in the stone slab under the sand, and the hole was the gray-white powder.

When we came to the Gobi Desert, of course, we didn't have diving equipment, so I could only cover my mouth and nose as much as possible, and I couldn't take care of my ears, so I had to stuff them with tissues. The fat man wrapped the very thin rope around me a few times, and I slowly entered the sand as if I were in water.

I sat on the edge and put my legs on the sand, and I immediately saw that my legs were sinking into the sand.

If it weren't for the slight coolness and gravity, I would have thought I was entering a well. The fat man made an OK gesture and he was ready. Seeing that he tightened the rope, I didn't care about anything anymore, and just moved my ass and sank my whole body into the sand. For a moment, this falling speed almost made my heart skip a beat.

I covered my mouth and nose tightly, and after taking one last look at the fat man and the old generation, my eyes were also tightly closed, and then, there was a feeling of weightlessness that did not touch the bottom of my feet.

I can't estimate the speed of the fall, there is no reference, there is no sense of damping, I feel like I am in the water, and the surrounding me is like an endless void.

It's just that I don't have the feeling of water pressure in the shallow water, but the feeling of solid clinging to the body and keeping the body in a state of tension has always been around.

It was an unusually long time, but it wasn't really long, just in an instant, my feet touched the ground, and the passage was very spacious, and the fat man and his wife had little to worry about it.

I'm holding my breath to the halfway point, and I can hold it for less than thirty seconds at most, so I have to find an exit quickly.

I fumbled around in the direction I came down, but when all I touched was the walls, my heart was cold, and in the solid, I should have sweated, but it was immediately absorbed by the fine sand.

In the panic, my foot kicked a few times in the solid, but I didn't expect the unintentional kick to kick into the air, almost without hesitation, I immediately squatted down, and with my single hand, I felt towards the hole.

The tremendous pressure on my head and chest told me that there wasn't much time left. Inhaling water is not the same as inhaling solids, and if the lobes of the lungs are full of sand, the rest of your life will be worse than death.

This passage is a U-shaped design, but the corners are stiff and the passage is completely square. As soon as I looked up through the hole, I immediately knew that I was saved, because I felt a stuffy sensation in my head, and I inhaled the air that was not very fresh.

Taking a step forward, my arm was out of the sand, and I fumbled in the dark a few times before I realized that I didn't have a mother's flashlight.

I was already a little frightened in the darkness, but after taking another step, I immediately touched the stone steps in front of me, which I feared were the stone platform out of the bunker.

But in this step, I also made a new discovery under my feet, and under the fine sand, there seemed to be another thing, because the sand resistance was very small, and I immediately felt with my feet that it seemed to be a shoe.

Leaving my face on the sand, my hands reached into the sand, and with the help of my feet, I took the shoe out of the sand. After a few fiddling sessions, I couldn't see the shoe, but I could feel that it was an outdoor shoe like a travel boot or a combat boot. Although I was confused, I still wanted to climb up first and think of anything else, at least to call them up first.

Groping my way up the steps, I tried to climb up, but at this moment, suddenly a pair of hands grabbed me by the shoulders. I was so numb that I was almost scared out. But it was also in an instant that I knew that it was a man, a Caucasian.

The Caucasian had fallen into this sand pit, and had come down without any consideration for these problems, having thought that the deadliest ones would not cause much of a consequence, and that this mistake of not being planned at all put me in a dangerous situation.

The Caucasian pulled me up, and before I could react, I immediately felt a cold thing against my head, and I knew it was his gun, and almost at the same time, a flashlight lit up behind the muzzle, which was not for professional use, so my eyes just flashed.

In the backlight, I saw that the man was indeed Caucasian, and he looked at me, and immediately saw the boot I was still holding in my hand, and immediately took it.

"Thank you." The man spoke in a very gentlemanly tone, but the gun he had in my head did not make me feel any good for him.

He put on his shoes with one hand and looked at me a few more times: "Hello, we meet again." ”

I didn't answer, just looked at him, he smiled, and said, "Don't be stubborn, I won't kill you." ”

I raised an eyebrow and glanced at the rifle on the top of my head, and he noticed my eyes, so he also looked: "Don't worry, I won't kill you, but I don't know if you'll kill me for a while, so it's still necessary until I remove the obstacles." ”

I twitched at the corners of my mouth at the point of his logic, but he didn't pay much attention to it, and turned his attention to the rope on me.

"A few of you, you'd better tell the truth, otherwise, I'm not happy, and none of us will have a good time." As he spoke, his tone gradually lowered.

I knew that it was useless to tell lies at this time, so I said coldly: "Add me, there are three in total, and two are still on it." ”

The Caucasian looked at the sand, but the muzzle of the gun still did not leave my head, the gun was indeed modified by hand, and some of the saws were uneven. He saw the rope I was dragging into the sand a few times, and looked at me with a puzzled expression.

The rope was pulled outward three times, which was a signal made by a few of us, as soon as they found that the rope stopped, they notified me like this, and once I replied, then they would come down, otherwise they would immediately pull the rope to rescue me.

Seeing this, I had no choice but to answer truthfully. When the Caucasian heard this, he touched his beard, turned around and drew a dagger, cutting the rope. He barely thought about pulling the rope three times, and there was no response, because he was already ready to come down.

At this time, I realized that this time I might be wiped out, and I prayed in my heart that those two people must be smarter. He must not be able to control three people by himself, and even if he succeeds, it will not be too easy, so there will be some of us who will be killed or injured by him.

After he pulled the rope, he turned his head to greet me, and when he touched his waist and took out a bundle of rope, I suddenly felt dizzy, and scolded in my heart, are you all robot cats, with so many things on your body at any time.

But when he opened it, I realized that the bundle was not a rope, but a bundle of cigarette tendons that were extremely elastic like rubber bands.

He took down the next section, and I noticed that the thing could still be disassembled and combined, and there were metal rivets between the rubber bands, which could be removed or installed like carabiners.

This section was only a little more than a meter long, and as soon as he took it out, I knew what I was going to do, so I was ready to straighten up and wait for him to tie up.

When the Caucasian saw me like this, he said something that I did not understand, which seemed to be a mantra in his native language, and then said in Chinese: "It's very cooperative, then don't scream for a while." With that, he raised the gun in his hand again.

Of course I won't scream, the consequences of that are definitely better than resisting in the past, the fat man and the old generation don't know what the situation is, even if they shout, they can't hear it, and their position is almost waiting to be slaughtered by the Caucasus, resisting in the sand, there is no chance of winning.

Although this bastard didn't have a tone on his lips, he just said this lightly, but I obviously felt that it was very easy for him to kill people, but I don't know why he didn't kill us now.

I was tied strongly, this kind of rubber band was wound around me at least seven or eight times, and a few knots, it seems that the production process is very special, two sections and one button, I became a fat pig waiting to be slaughtered years ago.

The Caucasian index finger was put in front of his mouth, and he made a silent movement, and I closed my mouth directly, he didn't mean to gag my mouth, it seems that he was not worried that I would shout, which also proved from the side that as long as I shouted, the fat man and the old generation must have no way to live.

After a while, the lights were also turned off by him, and silence returned to here, except for some slight noises in the sand.
