But how to find this room or the basement is once again a problem before us, and as a result of the situation, of course it is not advisable to explode, because although this place is desolate, as soon as this sound is transmitted, we will be surrounded in an hour.

And even if we wanted to, we didn't have explosives or detonators in our equipment, because we couldn't get that kind of thing by conventional or unconventional means.

"It stands to reason that as long as it's a secret room, he should always have a door." As I spoke, I walked around, and immediately I noticed something different about the ground.

The rest of the place is still covered in snow. And this piece of land under our feet is still sand, and there is no snow left.

When the old generation saw that I was behaving abnormally, he asked, "What's wrong, have you found anything?" ”

I didn't answer right away, just fiddling the sand on the ground a few times with my foot. The old generation also noticed this problem, looked at the sand, and only heard him let out an oh sound.

Immediately after that, I saw that the old generation seemed to want to dig a hole in the sand. When he saw that his feet were not good, he took my knife and used it as a shovel.

The sand is not very deep, only a palm's height. After digging a few times, I heard the sound of the scabbard hitting the stone. The fat man, who had been searching halfway up the mountain, saw us digging sand at this time, and he was curious and wanted to come over.

At this time, we should be in the general headquarters of the Black Lama Bunker, there is a very large foundation, and there is a half-meter-high low wall around the foundation, and we are in this foundation pit.

The fat man flew and jumped off the platform that rose high on one side of the foundation. Originally, there was nothing wrong, and I didn't notice him, but I suddenly heard him scream, and I turned my head with the old generation.

Seeing that he didn't have any major problems but stood still, I asked suspiciously: "What kind of nerves do you have?" ”

The fat man raised his head, his face was slightly weird, his brows were still furrowed, he slowly raised his arms, and squatted down with extreme caution.

"My feet don't feel right, it's a bit like quicksand, you two quickly find something to pull me." The fat man whispered, he had slowly squatted down, and seeing the depth of the sand under his feet, I didn't feel that he was stepping on quicksand at all.

But looking at the fat man's appearance, it doesn't look like he is pretending. But if it's quicksand, it can't be just a little bit under the feet of a fat man. The two of us were not far from him, less than two meters at most, but his location was in the corner of the entire foundation pit.

"Do you feel wrong, there are big stone slabs under this sand?" The old man scattered all the sand that had been turned over, and under the sand that was not yet a palm thick, a blue-white gray stone slab was indeed exposed.

Seeing this, the fat man was also a little surprised, so he slowly withdrew his balanced arm and poked into the sand under his feet. It was only for a moment that I saw that the sand, which had been stable, suddenly lost its balance.

The sudden sinking was something the fat man didn't expect, and almost instantly, I saw that the fat man wanted to pounce out, but the sand collapsed too fast, and he fell directly into the sand without waiting for the fat man to make a big move.

When the sand first fell, I could probably see that the area under the fat man's feet was a circle, only the width of two manhole covers. Lao Dai and I didn't think about it anymore, and rushed up directly, one of us grabbed one of the fat man's arms, and then dragged it up desperately.

"Why is there a quicksand pit in this place, the black lama's habit is a bit strange." I pulled the fat man, my eyes kept on my feet, and I was indeed a little afraid that my feet would collapse as well.

It didn't take much effort, and barely felt the suction on the fat man, even though he was now half in the bunker. It was easy for the two of us to pull the fat man up.

"Oops, my waist." Holding my waist and complaining, I said, "You've got to lose weight, it's so heavy." ”

A few of us sat on the edge of the bunker, each panting, but not tired. The fat man patted the dust off his legs, and I just glanced at it unconsciously, and I saw the white sand on his pants.

Almost at the same time, the attention of all three of us was focused on the fat man's legs, and the old man grabbed some and twisted them in his hands. I also learned to get some of them, and I immediately noticed that these didn't seem to be sand, they were very fine, and there was almost no grain of sand.

I put a pinch of white-gray powder in the center of my palm, put it under my nose and sniffed it. There is no special smell, just the earthy smell of sand.

The old generation twisted it, and immediately I saw him stand up again: "Where is the sand pit just now?" The old generation asked suspiciously.

That's when I turned my head to look at the bunker where the fat man had fallen just now, but in an instant, I asked that question too. Where the fat man fell just now, where there should have been at least a trace, it was as if nothing had happened.

The sand here doesn't have much moisture, and even if you dig half a meter, you can see that the surface is still dry. There were only a few waves on the sand, and the outline of the original quicksand pit could not be seen.

A few of us squatted and cautiously walked to the approximate location of the bunker, and the old man continued to explore the sand with the scabbard until suddenly the whole blade sank into the sand.

The old generation is ready, so it is not trapped. As if trying to test how deep the bunker really was, he plunged the whole knife into the sand.

After the blade was all submerged, the old man did not stop, and then he directly lay on the ground half-upside down. The handle of the knife sank directly into the sand with the whole arm, and it felt like entering water without any effort.

I looked at the old generation and waited for him to give me the results. After waiting for a long time, he pulled out his arm with the knife.

"It's deep down there, and it's not there yet." As he spoke, the old man concentrated the remaining white-gray sand on the hilt of the knife into his palm.

"Nonsense, quicksand pit, of course it's deep, if it's only up to the knees, then what kind of quicksand is it called."

"It's not quicksand." The old generation held a small handful of fine gray sand, and made a gesture to hand it over to the fat man, but the fat man opened his hand and caught the sand from the old generation.

"This sand is very fine, and it is very dense, and it is not the same as this layer on the surface, it is filled in by hand, and I am afraid that there is a shaft dug manually." The old man put the knife horizontally on the bunker, but it did not fall directly as exaggerated as he imagined.

The fat man observed the fine sand in his hand, and I gently pressed the sand on the surface of the bunker, then turned his head and asked the old man, "Is this a trap?" As soon as I finished speaking, I had a stirring in my head, and immediately said, "I know where that Caucasian has gone." ”

As I spoke, I pointed into the bunker. It seems that the Caucasian is not a supernatural who can teleport, it turns out that he is carried on it by himself.

"He probably found out that there was one less of the three of us at that time, so he ran here to block you, but he didn't expect to step on it." As I spoke, I laughed twice, is this a self-inflicted sin that cannot live?

Lao Dai shook his head, and when I saw him like this, I immediately said suspiciously: "There is no other possibility, if he doesn't fall from here, then we should consider metaphysical things." ”

"It's not." As soon as I finished speaking, the old generation just replied with these two words.

The fat man threw the fine sand in his hand to the ground: "He means, this is not a trap. You see. Before I could ask, the fat man pointed to the ground for me to see.

"What about the fine sand?" When I took a look, I found that the gray-white sand that the fat man had just thrown on the ground had disappeared.

When he saw my stunned look, he put his hand directly into the yellow surface sand and slapped the sand. The top one was scattered by him, and slowly only a small spot remained in the palm of his hand, and among the large grains, I saw a fine gray-white sand.

"This thing is very dense and very delicate, not like sand, as long as it is sprinkled on ordinary sand, it will flow down the gap to the lowest layer." The fat man scattered the fine sand from his hand again, and I saw that the fine sand only remained on the surface for a while, and then fell into the yellow sand, and in a few seconds, there was nothing.

"This ...... This ...... "I was shocked for a long time and didn't say anything, this thing feels very similar to a thing I've seen before, it seems to be called space sand, but the shape of the object is very different."

At this point, I had already thought of the function of this shaft, but I was still a little strange about this purpose. Then he looked at the fat man in embarrassment: "Are we going to go down from here in a while?" ”

The fat man nodded, and I immediately confirmed my suspicion that this shaft was indeed a passage to the lower chamber or the space below the mountain.

When the bunker was still there, the place must have been covered with a floor, and the black lama wanted to go down to see his treasures, so he turned over the floor, got rid of the sand on the surface, and jumped straight down. Later, people searched for this piece, they would only think that it was an ordinary ground, and if they were unlucky, they would only be mistaken for quicksand, and if they were lucky enough to have a companion, the rescue would not be too difficult, after all, this was not really quicksand, and if they were unlucky, they would fall directly and be suffocated in solid.

Oh, that's not right. My mind has reached a dead end, if so, this shaft seems to only serve as a tomb, then how can it be a passage?

Looking at the fat man and the old generation, I asked again: "If you jump directly, you will be suffocated to death, it is all sand, how can you live." ”

"You're the kind of straight-up and straight-down structure you want." The fat man gestured to the ground as he spoke.

Before he could draw anything, I spoke again: "If you open a hole in the middle of the way, you may not be able to catch it every time, and if you open the hole underneath, won't the sand leak out quickly?" ”

After listening to my words, Fat held his forehead and sighed: "Haven't you flushed the toilet?" ”

At first, I didn't understand it, but as soon as I saw the figure he drew on the sand, I instantly understood it, and I thought to myself, it turned out to be such a structure.
