This cave is not big, but it is not small, and in the middle of the cave is the underground river where the water is very fast. The underground river is about three to five meters wide, wide in some places and narrow in others. The shore on both sides is relatively spacious. It's about two or three meters.

The cave is very high, as high as a three-story building, and it looks very empty.

The top is full of neatly arranged long stones, and it is at this time that I realize that this place does not seem to be an ordinary karst cave, but has been built by man.

Because the stones on the head are obviously not naturally formed, although there are many stalactites on the top of this cave, the traces of those closely connected long stones are still very distinct. It's definitely not natural.

Could this hole have been dug out by hand?

Before I could analyze the issue in detail, they had already stripped the clothes of the dozen or so corpses.

Just as we were holding those clothes and preparing to return to the secret room that Zhao Xiaotian said, we suddenly heard a loud noise from the upper reaches of the underground river: "Bang......"

Although the sound is not very loud, it is very loud in this closed underground cave.

I don't have to think about it to know that someone is blowing something up with explosives again.

". These bastards, they're not afraid of this hole collapsing, dogs. God really doesn't have long eyes, why didn't you bury all these bastards alive! Zhao Xiaotian scolded endlessly.

As soon as his scolding fell, something unexpected happened.

I felt a sudden "boom" sound in the distance, and the worst thing was that it was coming from upstream, and it seemed to have a chain reaction from far to near......

We were all stunned by the incessant rumbling. Only Zhang Yihan shouted very calmly: "Run, the cave is going to collapse......"

Zhang Yihan's scream didn't fall, and he pulled me and ran towards the cave that Zhao Xiaotian took us to drill before.

"God, I'm a muddy horse, Lao Tzu told you to bury them alive, didn't you bury us together......" Zhao Xiaotian shouted and scolded behind us.

The incessant rumbling of "Boom ......" continued, as if it was right behind us.

I couldn't help but turn around and shine a flashlight, and in this photo, I saw a picture that looked like the end of the world.

Not far away, on the top of the cave, countless stones and earthworks are falling down in large areas. The stones are long in shape, and most of them are stuck on the underground river after they fall, and they do not fall into the river. But it wasn't just the strips of stone that fell, there were piles of earth the size of a house.

This scene reminded me of dominoes. At this point, it was as if we were being chased by a row of dominoes. The space behind us was gradually being flooded, and I knew it would soon be our turn.

In fact, it was too late to say that it was too late, I just turned around and took a look, and immediately turned around and took Zhang Yihan and rushed forward. Originally, Zhang Yihan was running on the bridge in front of me just now, and I ran again, but at this moment, my feet didn't seem to hurt at all, and it became my bridge Zhang Yihan running.

Fortunately, our speed was quite fast, and when we saw that the landslide was about to spread to our side, Zhang Yihan and I took the lead in jumping into the small hole in the stone wall. Zhang Yihan was the fastest to react. So the two of us were the first to reach the "end".

Originally, it was Zhao Xiaotian who was running behind us, but the animal threw his backpack in front of us, turned around and ran back.

"Brother Zhao, what are you doing?" I exclaimed and shone my flashlight behind me.

It was also under this photo that I found out that Yang Lili seemed to be injured, Li Dakui was carrying a backpack, holding her and rushing towards us, Zhou Rong's leg was also limp, originally his speed should have been the fastest, but at this time he ran at the back. Originally, he was supposed to be carrying a rucksack, but it may have been after a foot injury, so he threw it away in order to reduce the weight.

Seeing that Zhao Xiaotian hadn't run to Zhou Rong yet, Zhou Rong began to wave to Zhao Xiaotian: "Don't worry about me, go back quickly......"

"Damn, Shao Teh and Lao Tzu are talking nonsense......" Zhao Xiaotian had already rushed to Zhou Rong after speaking. As soon as he bent over, he ran away with Zhou Rong on his shoulder.

At the same time, Li Dakui and Yang Lili had already rushed to the cave. There were more than a dozen caves side by side in this area, so each of us occupied a cave entrance. Because we have walked before, the entrances of these caves are basically connected, and you can communicate with each other not far inside.

Seeing that Zhao Xiaotian was carrying Zhou Rong more than ten meters away from us, all of us shouted in unison:

"Brother Zhao, hurry up and ......"

"Xiao Zhao, hurry up and ......"

"Zhao Xiaotian, hurry up and ......"

The reason why we shouted so loudly was because we saw that the landslide behind Zhao Xiaotian was less than ten meters away from him, and maybe the next moment, the stones and countless tons of soil on his head would suddenly collapse and bury him and Zhou Rong here.

At this moment, Zhao Xiaotian's every step touched the nerves of each of us.

I could clearly see the green tendons on his head popping up, in fact, he was very fast now, but the stones above his head were falling faster. When he was less than five meters away from us, several large rocks fell above his head.

At this moment, Zhao Xiaotian let out a loud roar with all his might: "Ah......"

Before the roar fell, Zhou Rong flew towards Li Dakui.

Just when Li Dakui just caught Zhou Rong, at this critical moment, I kicked the ground with both feet and flew out of the hole desperately.

"Xiaolin......" When I flew out, Yang Lili and Zhang Yihan shouted in unison.

Just as I pounced on Zhao Xiaotian, I felt as if a hand was stretched out behind me, but I didn't have time to see who it was, because when the man grabbed my waist with both hands, Zhao Xiaotian and I had already flown into the underground river.

Before I fell into the water, I felt a strong wind overhead, followed by a deafening loud noise: "Boom......"

The loud bang rang in my ears entirely.

The reason why I rushed out at that time and knocked Zhao Xiaotian down was because I saw that the boulder on Zhao Xiaotian's head had fallen. If I hadn't done it hard, he would have been crushed alive by the boulder before my eyes.

At that time, I had only one thought, that is, I could avoid being crushed by a boulder by jumping into an underground river.

I didn't think it was the same as jumping into the river.

I only remembered this question after I fell into the water, and I guess I was awakened by the cold and biting water.

I even regretted doing this just now, because it was also death, and it didn't matter if I accompanied Zhao Xiaotian to die, but I still took Zhang Yihan's life.

It was only after I fell into the water that I realized that when I flew out just now, Zhang Yihan also pounced with me, and of course I could feel the softness of the two balls on my back.

The situation in which we fell into the water was like this, I was holding Zhao Xiaotian's waist, and Zhang Yihan was holding my waist.

After we fell into the water, I could still feel the rumbling behind me.

Out of human instinct, we don't care if we are hit by a rock after falling into the water, and we immediately throw ourselves out of the water.

But as soon as my head came out of the water, I looked up and saw a large boulder falling down on me from the top of my head, and not far behind us, it had already become a mountain of dirt that could no longer be seen......

"Hold on to me......" I shouted, pulling Zhang Yihan and Zhao Xiaotian violently underwater. Then he hurriedly grabbed Zhao Xiaotian's belt with one hand and paddled with the other. Low-grade sarcasm.

Zhao Xiaotian was paddling with both hands in front, I was paddling with one hand as he reached out and grabbed him, and Zhang Yihan was also holding my belt with one hand behind me and paddling with one hand.

At this moment, the three of us still dislike that the river is not urgent enough.

The rumbling behind us continued, and the speed of the collapse seemed to be proportional to the speed of the river, and it was always behind us, which was also a chance to breathe.

We swam for a while, then showed our heads and took two breaths, then swam a few more times. Finally, after about ten minutes, we seemed to enter a hole in the ground with a strong current. Because we can clearly feel that the current is getting faster, and the channel is narrowing.

Happily, though, the rumble behind him is gone.

When the underground river enters a small cave area, it means that there will be no more landslides.

However, before we had time to rejoice, I suddenly felt my body instantly weightless, as if I had fallen into a bottomless abyss.

"Ah......" I heard the screams of Zhao Xiaotian and Zhang Yihan.

I didn't call it because I was afraid of heights, and when I was in the police academy, once the whole class went out to play, and I went to play a bungee jump in order to be angry, and I fainted as soon as I jumped down.

It was the same this time, as soon as I lost weight, I fainted.

However, it seemed that not long after I fainted, with the sound of falling water, I was awakened by the powerful impact again.

As soon as I woke up, I threw myself up desperately, and after a while, I finally got up.

When I showed my head, I heard Zhao Xiaotian and Zhang Yihan shouting at me in the distance:

"Xiaolin, you are not allowed to die, I heard that there is no ......"

"Xiaolin, don't scare me......"

The voice of Zhao Xiaotian in the front, and the voice of Zhang Yihan in the back, hearing that the two of them were so nervous about me, my heart warmed.

I was about to speak, but I couldn't help but let out a violent cough. I choked on the water and took a few more sips.

But when I came up again, I heard two sparse sounds of water swimming towards me from far and near.

The water here has become calm, and I can feel that it seems to be a large underground lake. I could hear that I was far away from the sound of the waterfall in the distance. They probably heard me splashing too, so they quickly swam to me.

"Grass and mud horses, I know that your life is hard, and you are not so easy to die." Zhao Xiaotian said happily: "You're going to die, Hanhan will cheapen me." ”

"Why don't you die!" Zhang Yihan scolded angrily: "When is it, are you still in the mood to joke." ”

At this moment, there was a sudden sound ......of violent water not far away, as if something was swimming towards us, and it seemed that this guy was not small.

When we heard this, all three of us were stunned. The three of us formed a circle, constantly treading water under our feet, but we were holding each other's hands, and neither of us was willing to let go of anyone, as if we were afraid that we would be left alone.

......The sound was still ringing not far from us, and it seemed to be getting closer and closer to us.

At this moment, Zhao Xiaotian said in a low voice: "Do you think there will be anything under this underground that we haven't seen prehistoric creatures or anything?" ”
