Since we are standing in the sand table, of course there is a lot of sand under our feet. Usually, people use the term "Ganges sand number" to describe something that is "as much as infinite", and it is difficult to distinguish a very fine substance like sand with a quantifier like "grain".

Right now, if something hides in the sand and is about the size of a grain of sand, finding it is like looking for a needle in a haystack.

"I'll find it." Paddle Lanzhou slowly squatted down, plucked his hands, and held the sand full.

I smiled silently, crouching down like she did, and picking up the sand.

There are too many treasure stories in the Gobi Desert, and in the past when transportation was blocked, the Central Plains and the Western Regions could only rely on camel caravans to transport goods. Whether they came from east to west, the camel's back was laden with gold, jewels, silk, utensils, scriptures, and books.

The black winds and sands in the desert come and go so often that even the most experienced guide cannot predict climate changes. As a result, every year, dozens of camel caravans suffer in the desert, and some of them come and go, and they can enter the desert but cannot get out of the Gobi.

When the black wind and sand crossed, all the treasures on the hunchbacks were buried under the sand, at a depth of several meters or even more than ten meters or tens of meters, becoming a part of the desert.

Treasure hunters who are greedy by nature want to dig up these ownerless treasures, but after hundreds of years of hard work, treasure hunters have found that this way of making a fortune is simply not feasible, and the investment is infinite and the output is unlimited.

Once the treasure is involved in the desert, it will only sink deeper and deeper until it reaches the heart of the desert, a place that can never be reached by manpower.

It is said that the "Heart of the Desert" is the birthplace of the quicksand wells in the world's major deserts, and all things that are lost in the "Heart of the Desert" will gather in the "Heart of the Desert" and become the nourishment of its eternal power.

I thought of this just to illustrate that it was impossible for the boat to find anything on the sand table, because what she was looking for didn't exist at all.

When I think of the "heart of the desert", I suddenly feel that something is slowly rising and falling, like a sleeping person breathing slowly and long.

"Lan Zhou, have you found anything?" I asked softly.

I know that if people stay in a closed or semi-closed environment for a long time, they will have 100% hallucinations, visual hallucinations, and auditory hallucinations, which are determined by the physiological structure of human beings.

This is very fatal, and in those cases of perverted murders that occur in closed room captivity, hallucinations are the only trigger.

Oaran Lanzhou relaxed his fingers, and the sand particles leaked silently from between his fingers.

She repeated the motion, using her fingers as a sieve, picking up and leaking the sand from her feet again and again.

"It's time for us to go." I whispered.

As I looked at her, I seemed to hear the sound of a heartbeat of "pounding, pounding, pounding" in my ears.

"Thirty beats per minute, that's the heartbeat of a person in deep sleep, a healthy heart – where? Where are the people? Why can we hear his heartbeat? Is he just sleeping on this sand table? "I couldn't control my mind and ask these kinds of unwarranted questions over and over again.

"Did you hear that? The sound of a heartbeat? Pao Lanzhou asked suddenly.

I struggled to control my emotions and nodded quietly, "yes, it seems to be a voice." ”

"This sand table is alive, that is the heartbeat sound made by the sand table, which is the legendary 'desert heart'. So, if you want to ask about the secret buried in the desert, you have to ask it. The secret of Dunhuang Tianji is also buried in the desert, you say, should we ask it? Paddle continued to ask.

I can't deny the existence of the "heart of the desert", but I also hate to admit the truth of that legend.

As early as a hundred years ago, that is, when the stethoscope was just invented, a European doctor predicted - "Everything has a heart, as long as you choose the right medium tool, human beings can hear all the heartbeats in this world, including the sky, the sea, the earth, and the air." Human beings' understanding of the world is only to see, hear, smell, and touch, which is only one billionth of everything, and there are so many things that human beings cannot perceive their existence at all. Therefore, what human beings have to do all their lives is to create media to help them understand the world outside their bodies. The more you know, the more humble humanity becomes. ”

"The sand table is dead, there's no doubt about that." I say it categorically.

"So, where does the heartbeat come from?" Paddle Lanzhou asked.

"It's just an auditory hallucination, like the tsunami you hear when you cover your ears." I explained lightly.

"Impossible, I clearly perceive that there is a secret passage on this sand table, and the sound of the heartbeat comes from the dark passage. The Yellow Flower Society has done a lot of research to confirm that the 'heart of the desert' does exist. Pao Lanzhou said, and immediately added in a low voice, "If this research result is made by Huang Huahui, it will definitely not be convincing by scholars around the world, but I will correct it - this result is obtained by the Y Force of the 51st region of the United States after 6,000 cases, and it is probably impossible for others to refute it, right?" ”

I was slightly stunned and nodded subconsciously.

The Y Department of Area 51 in the United States is very special because it is not an organization related to high-tech fields such as scientific exploration, military combat, extraterrestrial life, and space exploration, but a civilian organization with desert research and geological drilling as its core business.

Countries around the world pay attention to Region 51, mainly to get a glimpse of its high technology, and do not care about institutions such as the Y sector.

A long time ago, when I was planning to leave Perak Hall and move to Dunhuang, I spent some time learning about phenology in the Gobi Desert. It was at that time that I read some examples of the work of department Y and research reports.

It was at that time that I gained a deeper understanding of the "heart of the desert".

Assuming that the theory of "the heart of the desert really exists" has been confirmed by Department Y, then it must be more than 80 percent correct.

"Okay, as you say, what are we going to do now?" I didn't say any nonsense to question and refute, I just looked for the quickest solution.

We've been down for a long time, and it's not the best idea to stay in danger for a long time.

"Find the secret passage, the location of the secret passage on the sand table, that is, the correct location of the secret passage on the Gobi Desert. Uncover the secrets of the 'Heart of the Desert' and all the secret places built on the desert will be solved. Paddle Lanzhou said.

"Okay, let's get started, but there is one thing, we must act hand in hand, not half a step apart, to avoid being victimized by hallucinations." As I spoke, I stepped forward and grabbed the left hand of the oar.

"I'm sure it's not a hallucination, because I've been tested by all of the special nerves of the Y department, and under no circumstances can I hallucinate." She said.

"You forgot, Zuo Fengshou released the 'Incredible Worm' in the underground secret room." I reminded her.

"That kind of physical Gu worm can't produce mental interference, my nerves are iron-beaten." She shook her head and smiled.

Next, we slowly conducted a carpet search on the surface of the sand table. If it is divided according to the actual geographical environment, it is equivalent to taking Dunhuang City as the center and measuring the surrounding mountains and rivers.

As I said, there are no dark passages on the sandbox.

I and I have even picked up every pile of sand with our own hands, only to turn the sand table over, empty all the sand, and empty the whole plate. Unfortunately, we are on the sandbox and cannot do that.

"You see, there's no secret passage here." I came to a conclusion.

"Then it proves that there is no secret passage leading to the 'heart of the desert' in the desert around Dunhuang? However, this is a paradox, because as far as I know, the existence of the anti-thief pit is due to the collapse of the quicksand manhole that formed such a large natural pit. Paddle Lanzhou said.

My understanding of the anti-thief pit only stays on the map and local chronicles, and I have passed it a few times, but it is only a superficial view.

The local chronicles do not mention that the anti-thief pit is related to quicksand wells, and even says that the entire local chronicles of Dunhuang do not mention that there are quicksand wells around the city.

This is understandable, any danger will affect the development of local tourism. Since there is no quicksand in the anti-thief pit now, it is natural that this kind of negative information should not be publicized publicly.

At the mention of the anti-thief pit, my heart hurt again, because there are still many things unresolved over there, and I still don't know what happened to Gu Qingcheng.

"There's no denying that quicksand wells are a gateway to the 'heart of the desert,'" I said only half a sentence and didn't continue.

As we explored on the sand table, we passed by the location of the anti-thief pit twice. It was clear that there was neither sand nor a dark passage, just a small depression in the slab.

The oars turned their heads and looked at the location of the anti-thief pit.

Almost at the same moment, it occurred to me that "the ground can be dug up, and the sand table should naturally be able to be pierced." We can't turn the sand table over, but we can make a few holes in it and see what's under the sand table and under the secret room. It's now, it's the anti-thief pit as a breakthrough-"

"Where it should be, dig in." Paddle Lanzhou said.

I took a deep breath and was relieved to know that we were just as responsive and had the same solution.

Together, we strode together to the hollow that represented the anti-thief pit.

On the surface, the depression is only a small piece of two inches square and one inch deep from the surface of the cement slab. If it weren't for the fact that we paid close attention to the anti-thief pit before, we would probably have missed this detail.

"This is it, once the quickmanhole is pierced...... At the beginning, the sand on all sides will continue to fall, and after it has fallen to a considerable volume, the quicksand will produce various forms and rhythms of undulating and tumbling, just like the simulated waves on the stage. When the quicksand well is in motion, any solid that is put on it will disappear instantly, and it will be carried to the infinite depths with the flow of the sand. Oaran explained the boat.

I nodded, this is the most appropriate explanation of the term "quicksand manhole" in physics and geology.

The formation principle of quicksand wells is very complex, which is related to various external factors and internal structures such as earth gravity, sand saturation, sand friction, aerodynamics, etc.

In the jargon of explorers, quicksand wells are also known as "desert swamps", which means "to fall into them is to perish".

"Don't worry, we're breaking here, and it won't have any impact on the real world outside." I smiled hard twice to comfort the oars.

"What I'm worried about is that once the outside world discovers that the anti-thief pit is the key to uncovering Dunhuang's heavenly secrets, then the anti-thief pit will become a ...... The biggest ...... in the First World War of Dunhuang Victim. Oaran Lanzhou said gloomily.
