Running to Lu Dachuan's side, I told him the speculation that the sinkhole was a cemetery. He twisted his neck and looked around: "Don't say it, it's really kind of interesting!" ”

Such an important discovery, looking at his lukewarm reaction makes people really bored: "Yes, no, no, what does it mean to be so interesting?" ”

Lu Dachuan said unhurriedly: "It looks like it, but don't forget, the funeral custom of the Tibetan people is sky burial." Even if there were burials for individual reasons, they would not have been on such a large scale. ”

"Who said it was the grave of the Tibetans! Have you forgotten where the Duliba Stone Disc was first found? "I recited the legendary discovery of the stone saucer," Qi Futai, a professor of archaeology at Peking University, and his students in 1938 when they explored a series of caves in the Bayankala Mountains near Qinghai Province.

They found a number of clean graves, which contained skeletons about 138 centimeters tall. These skeletons have huge skulls and small, fragile bodies.

There are no inscriptions in the tomb, but there are hundreds of stone discs about 30 centimeters wide, each with a 2-centimeter hole in the middle, and each disc is engraved with two small grooves around the hole that twists from the edge of the disc to the center of the disc, like a Fiestus disc......"

Lu Dachuan patted his head: "I only think about their safety, how can I forget this stubble?" ”

Thinking of Lu Keqin, they don't know what happened? My excitement about discovering that the stone piles inside the sinkhole might be alien burials vanished: "It's better to find them!" ”

Lu Dachuan pointed to the entrance of the sinkhole above his head: "Let's take the sinkhole as the boundary, first search the right, and then the left." ”

We didn't disagree, Lu Dachuan took the lead and walked on the right side of the cave, I was a little scared, I didn't want to walk at the end, and quickly followed him. After walking a few steps, I found that Hu Xiaoming was not following me, but walking alone on the side of the wall, and immediately felt extremely uncomfortable on my back, and always felt that there was something behind me, and I also knew that it was my own psychological effect, but I still couldn't help but look back, and the more I looked at it, the more I felt hairy.

Lu Dachuan noticed my small movements behind him, turned around and shone a flashlight in the middle of the cave and said, "Why don't you go over there, what are you doing behind me?" It's sneaky. ”

"Huh? What did you say? "I pretended to be confused, but I actually understood in my heart that the huge cave was separated by countless stone piles and many roads, like Hu Xiaoming, the three of them went hand in hand, and each person looked at their feet and left and right sides across the stone piles, which not only expanded the search range but also saved time.

"Let you go to the other side like Lao Hu, why are you so stupid!" Lu Dachuan turned to the left beside the stone pile beside him and walked to the aisle on the other side, "Look carefully, this place is full of stone floors, and you can't leave footprints, mainly to see if they have left anything behind, or a mark for us." ”

"Oh." I was extremely reluctant and helpless, both of them were not far from me, and I couldn't say that I was afraid.

There is no Lu Dachuan in front of me, my vision suddenly widened, at this time the hole in front of me has long been gone, it has become pitch black, three flashlights with everyone's movement, the shaking flashlight light reflects the shadows of large and small stone piles constantly changing, as if alive, I can't bear not to think nonsense, hard to walk forward, while checking the ground between the stone piles on both sides.

I don't know how long it took, but we finally searched the right side of the sinkhole, and found no trace of them except for the stone pile or the stone pile, and we didn't find anything unusual in the cave.

"The evil door is gone, didn't they come down?"

"It's not down, it's a big trouble, we have to go to the lake to find it next!"

"Don't talk nonsense, you have to dig three feet into the ground."

Lu Dachuan is in front, Hu Xiaoming is behind, I am in the middle, the three of us walked to the bottom of the sinkhole, ready to check the cave on the left, I looked up intentionally or unintentionally, and felt that there was something missing from the entrance of the cave, but I couldn't remember what it was for a while.

I thought to myself, we had already walked out a long time, and the more I thought about it, the more wrong it became: "You didn't notice what was missing from the exit?" ”

Lu Dachuan said: "There is nothing at the entrance of the cave!" ”

"That's not right! Wrong! It's definitely not the same as when we came down. ”

The two of them stood on their feet and looked back at the small piece of sky light in the cavern of the black hole.

"What's the difference, aren't those rocks still there!"

"I didn't say ...... the stone pile"

Hu Xiaoming asked: "It's been so long, have you seen anything else besides the stone pile?" ”

"Let's take a look in the past, Zheng Shuang, this kid may not be able to do anything else, he observes things carefully like a girl, not something that we big men can compare!"

"You're really lifting me up!" I glanced at Lu Dachuan, turned around and ran back. Before I could run to the front, Lu Dachuan shouted behind me: "Dog, why is our hiking rope missing?" ”

Three strong flashlights illuminated the snow in front of me, and I saw that the rope hanging in the pit after we came down was gone, and there was nothing else in the sinkhole except the stone pile, which was someone who wanted to trap us in it, and the three of us were half cold in our hearts.

Sister Keqin, did they also encounter the same situation? The thought flashed through my mind, and I turned around nervously and shouted, "Sister Keqin—"

Lu Dachuan slapped me on the head: "I can't see a single figure, what are you kid shouting nonsense!" ”

"If they had come down and the rope would have been gone, they would still be trapped in this hole!" I muttered, ignored them, and ran to the left of the cave. Hearing Hu Xiaoming behind him: "Dachuan, it seems that your eldest brother can't run!" ”

"Hurry up, when do you still have the heart to say this!"

The left side of the cave is also wide and deep, and the stone piles on the ground are one after another, which seems to be endless, and it looks like it is better than the right one, and I don't know where the courage came from, I don't care whether Lu Dachuan and Hu Xiaoming catch up at all, just run forward.

It didn't take much effort to get out of breath and I couldn't help but slow down. Lu Dachuan and Hu Xiaoming grabbed my two arms left and right.

"The mountaineering rope was taken away silently, I don't know what is hidden in this hole, you can't find them in such a mess, you have to put yourself on it first!"

Lu Dachuan's words were like a slap in the face, I suddenly sobered up, and my mind quickly reacted, assuming that they found the sinkhole, and climbed the rope down to the sinkhole like us, and when they wanted to go out, the rope was taken away, there would be three situations: first, they were guarding under the exit, waiting for us to rescue; Second, look for other exits in the cave; Three, the guy who took the rope controlled them, or harmed them...... I can't imagine what would happen to me if I found their bodies somewhere in the cave? Not to mention that this expedition started because of me, just talking about the feelings I have with them in the past few days, I can't stand it. Especially Lu Keqin, I'm not sure if our relationship is love, but I know very well in my heart that my attachment to her now is no less than that of my mother when I was a child.

"Let's go!" Lu Dachuan pulled me, "Why did you kid get a demon obstacle, so you don't run around, why don't you stand and don't leave?" ”

Lu Dachuan interrupted my thoughts, I didn't tell him what was in my heart, and said simply: "I guess there are other passages in this cave." ”

Lu Dachuan said: "It's not reasonable for me to think about it, even if they are like us, they have lost their ropes and are trapped in this sinkhole, they have guns and signal flares, they should send us a distress signal......

I was about to express my opinion, but Hu Xiaoming said: "You forgot that you were by the lake, and when I saw the two of you, you couldn't see me." It's very likely that they signaled, and we were still wandering around outside the mountain and didn't see it. ”

"Even so, they should leave a mark to remind us of the danger here or where they are going!"

I interjected, "If the rope can be taken away, the mark can be destroyed!" ”

Lu Dachuan said: "Our habit of making marks is to use a knife to carve arrows indicating the direction on relatively eye-catching rocks or relatively large trees or directly leave messages, and if the marks are destroyed, they will also leave traces of destroying the marks......

"The most eye-catching stone here is the cave wall, we have looked everywhere we walked, and found nothing, these stone piles are eye-catching enough, but unfortunately there are too many!"

"So let you play your strengths, take a closer look!"

At this point, the cavern in front of us narrowed and curled visibly to one side. With the shrinking of the space, the stone piles on the ground have been reduced from the original horizontal row of ten piles to six or seven piles...... Four or five piles of ...... Then it was reduced to two piles side by side, each next to the cave wall on both sides, and the road left in the middle was barely passed by two people shoulder to shoulder.

The mountains around the lake looked like a bull's horn on the outside, and the hole inside also looked like a bull's horn, didn't we come to the end, I thought to myself to raise my head, the flashlight beam shone straight forward, and sure enough, a triangular cave wall blocked the way more than ten meters in front of us.

At this time, we looked at almost all the places in the cave that could be seen, but we still found nothing, and seeing that there was no way to go ahead, I was completely at the bottom of my heart, and looked at Lu Dachuan: "What should I do?" ”

Lu Dachuan ignored me, stopped looking left and right, and walked forward quickly.

I didn't understand what was going on, so I asked Hu Xiaoming, "Is there anything wrong ahead?" ”

"I didn't see it!" Hu Xiaoming's face was also questioning.

Lu Dachuan walked faster and faster, and when he touched the cave wall with a few meters left, he strode up.

Is he going to hit the wall? Hu Xiaoming and I didn't look back in shock, when we saw Lu Dachuan turn around and shout at us: "What the fuck are you still doing there, there's a hole here!" ”
