The passage was too narrow, Liu Yunsheng was in front of me, I couldn't see anything at all, and I didn't dare to say anything if I wanted to ask questions, so I could only keep looking at him and asking him what was going on.

Liu Yunsheng ignored me, retracted his body after making a silent gesture, turned off the headlamp with a "snap", and then supported the stone walls on both sides with his hands and feet to suspend his body in the air, and slowly crawled towards the darkness ahead.

Soon he disappeared into the range illuminated by my headlamp, and Xiao Wu behind him tugged on my trouser leg and asked what was going on, but he didn't know that I was also confused, and gently kicked him to stop talking nonsense, and then I turned off my headlamp and waited quietly in the dark.

The others didn't know what was going on, and when they saw me turn off the lights, they all turned off their headlights, and as the lights went out one after another, the darkness around us came like a tide, and there were many small sounds that followed, and I pricked up my ears to distinguish them, and I could hear the sound of breathing, the sound of heartbeat, and an indescribable rustle, as if there were countless insects crawling around us.

I've not had a good feeling for reptiles since I was a child, and when I heard this, I felt a little numb on my scalp, but small insects are generally phototaxis, and it shouldn't be a big problem for us to turn off the light source now.

After waiting for about ten minutes, I heard another rustling sound, the sound of cloth rubbing against the rocks, and I don't know how many times I heard it along the way, so it was easy to tell.

Raising his hand and pressing the headlamp, he saw that it was indeed Liu Yunsheng who came back, because the passage was narrow and he couldn't turn around, he could only crawl backwards towards us, but this difficult posture didn't seem to have any effect on him, and the speed was still fast.

After a few breaths, he retreated in front of me, and when there were still a few centimeters left, he stopped as if the sole of his shoe was equipped with a reversing monitor, and before I could speak, he curled up and reached out to turn off my headlamp, and whispered in the dark: "Something is wrong ahead, hold on both sides for a while, no matter what happens, don't touch the ground!" ”

After saying that, Liu Yunsheng climbed forward again, I wanted to ask what was on the ground in front of me, but I could only give up when I saw this situation, and after conveying his instructions to a little five, I also followed his example to support the stone walls on both sides and let my body hang in the air, and then moved forward little by little.

I watched Liu Yunsheng climb easily just now, but I didn't know how difficult it was until I got started, and at the same time, I had to fight gravity while exerting force horizontally, which was a great test of arm strength and muscles in the core area.

After crawling for a long time, I only advanced less than five meters, and my arms were sore as if I had soaked in old vinegar for a night, and I desperately wanted to rest, but when I thought of Liu Yunsheng's serious expression when I asked me not to touch the ground, I still bit my mother and continued to crawl forward.

In the later stage, I couldn't feel my arm at all, just mechanically repeating the action of crawling forward, just when I was about to faint, a hand suddenly dragged on my chest, and then I heard Liu Yunsheng say lightly in the dark: "You can come down." ”

"Trick is a puppy?" I asked casually with a twitch in my brain, Liu Yunsheng "um" and pressed the headlamp, and I fell directly to the ground as soon as I saw a flower!

Liu Yunsheng dragged me aside, and went to the exit to pick up the others, I lay on the ground for a full dozen minutes before I came back to my senses, sat up and found that this is a relatively large space, the area is almost twenty square meters, the height is about more than one meter, not too high, but sitting up straight is no problem.

Everyone else was lying around, and Liu Yunsheng was holding a flashlight to check the crack on the other side, which was about the same size as the crack we had passed before, and it was estimated that he would continue to suffer next.

"What's in that crack just now? Why don't you let us land? I leaned over to Liu Yunsheng and whispered.

"Nothing." Liu Yunsheng said without looking back, I was stunned for a moment and didn't understand what it meant, and he didn't explain much, the cat bent back to the mountain crack we just drilled out, and shone it inside with a flashlight.

I leaned over and immediately understood why he didn't let us land or turn on the lights, because there was no ground on that stretch of the road!

The illumination range of the flashlight is much larger than that of the headlamp, I saw that on the ground when we came, there was a crack with a length of nearly 20 meters, the crack was about one person wide, and the bottom was pitch black I don't know how deep, once I fell down, I basically couldn't climb up, and I had a slight fear of heights, if Liu Yunsheng told me this situation before, I would definitely not climb from above!

"Don't tell anyone else." Liu Yunsheng whispered, I nodded in understanding, and then he continued to inspect the crack we were about to enter.

Xiao Wu wanted to come over and see that I stopped him, anyway, we have passed through that crack now, and it doesn't make any sense to let them know how thrilling it was just now, it will only make others feel afraid.

After resting in this space for half an hour, and when everyone's strength was almost recovered, we drilled into the cracks one by one in the same order as before.

This place is a little more spacious than the previous section, and the gravel on the ground is relatively flat, so it is not so tiring to climb up, and an hour later we arrived at another spacious space, Liu Yunsheng raised the flashlight and looked left and right, and his face suddenly became solemn.

I noticed the change in his face and hurriedly asked, "What's wrong?" Any questions? ”

"It doesn't seem right here," Liu Yunsheng frowned and replied, "I haven't been to this place, this is not the route I took last time I left, there are a lot of new cracks here after the earthquake, I'm afraid there will be more forks in the road." ”

Hearing this, I breathed a sigh of relief, chuckled twice and comforted, "Don't worry, we will definitely be able to go underground." ”

Liu Yunsheng looked at me suspiciously, and I took out a cigarette and explained: "The cracks here are because the mountain structure is unstable, then the source of all the cracks must be the most unstable position in the mountain structure, just like the main stream and tributaries of the surface water system, our goal is the source of the entire water system, no matter how complex the tributaries of this water system are, as long as you go upstream, you will always find the source, it is nothing more than taking some detours." ”

"That makes sense," Liu Yunsheng nodded, and then changed his words: "But what should we do when we come out?" So many forks in the road will increase the difficulty of a lot. ”

"Isn't that easy?" I smiled, took out two glow sticks from my bag and lit them up and inserted them in the rock crevices: "We make a mark every time we go to a fork in the road, and when we come out, we will follow the mark, but from now on we have to speed up, this kind of glow stick only shines for twenty-four hours, and the longest will not exceed thirty hours......"

I deliberately didn't finish it, but the meaning was already obvious, the glowstick was our only hope of coming out, and if we didn't get out before the glowstick was completely extinguished, then we might never get out.
