I was taken aback, so I was not wrong in my speculation just now? However, this doesn't make sense, how can there be a waterfall underground? Could it be the junction of an underground river?

I glanced forward a few times, and could vaguely see that there was indeed water flowing down at the end of this stream, Uncle Quan seemed to realize something, and ran forward, and then we followed in fear, and sure enough, a waterfall appeared in front of us, because it was too dark around, we could only see part of it, and there was no end in sight above the waterfall, only one by one water flowed down.

Uncle Quan said: "It's okay now, if there is a waterfall, there must be an exit." ”

But I couldn't be happy when I saw all this, even if there was an exit, it was at the source of the waterfall, but we didn't have anything in our hands, so it was unrealistic for us to climb up the waterfall with our bare hands to find the exit.

Uncle Quan walked around the waterfall a few times, and didn't find anything to climb, I couldn't help sighing, I looked at the waterfall, and the vision was a lot wider, but I still couldn't see the end, and I also retreated in my heart, according to this, this waterfall will not be very low.

Uncle Quan and others are looking for something to climb around, I can't sit still and wait for it to happen, I looked around, in addition to the towering wall, there is only the turbulent river left, I walked to the wall, looking up at a darkness, as if higher than the waterfall, I reached out and touched it, it was as cold as ice, I instantly stretched out my hand, the touch just now told me that the wall is very smooth, it should be after the stone is polished, so this is artificially polished? A lot of questions immediately came to my mind, why is there a waterfall in this place? Is this river course a natural formation? How do you explain the stone slabs on both sides of the river? Could it be that it is also naturally formed? If there is any evidence that this wall was formed naturally, it means that before this, the water flow here was very large, and the passage where we stood was also flooded, so the washed stone wall looked like it had been polished. I crouched down and looked at the surface, and there was obviously gravel on the ground, and the ground was not smooth, so I was wrong.

I was shocked, that is, this place was excavated by hand? I shook my head, no way! I looked back at the swarthy abyss, and a chill ran down my spine. This place shouldn't be so simple, since this thing has been excavated, there must be a reason for it.

Suddenly, an idea popped into my head that since it was dug by hand, the waterfall would definitely leave some chisel marks for people to climb. Where are these gouge marks? I walked to the side of the waterfall and leaned close to the wall, and all the walls here were smooth, could it be that the people who dug here were hanging with ropes? The amount of work is so large that I don't think it's possible.

I saw Uncle Quan lying on the wall at the end of the road, very strange, I walked over, Quan Juncai put his ear to the wall, seemed to be listening to something, unusually quiet and serious, I didn't disturb him, so I also imitated his movements, pasted to the wall, there was a "rumbling" sound from the wall, there was nothing strange.

I raised my head and asked, "Quan, Quan......" The moment I looked up, I saw something behind the waterfall, and my head exploded in an instant, and I couldn't speak, it turned out that Jun Juncai was not listening to something, but looking at something.

There is an iron chain as thick as a leg hidden behind the waterfall, the more I look at it, the more I feel the explosion, there is an inexplicable fear from the bottom of my heart, the iron chain leads directly to the ground, this is only a bare part, the other part should be on the top of the waterfall, or, straight to the sky?

"All... Uncle Quan, this...? Jeon Juncai ignored me and still stared blankly, and several other people heard our voices and groped for it.

"Did you find an exit? Sky... Where did this chain come from? ”

"Great, just climb up the chain and we'll be able to get out!"

Xiao Qi snorted coldly: "You can try it first." ”

My mind was still a mess, I looked in the direction of the waterfall, and my eyes gradually adjusted to the darkness here, and I could clearly see that under the waterfall there were four huge iron chains of the same size, extending up to the waterfall, and falling down into the dark abyss, although the water was very turbulent, but the iron chains were still unmoving, as if they were fixed there, and the weight of this pile of things can be seen from this.

Uncle Quan took a deep breath and said to us, "I can only climb that thing now." ”

Xiao Qi was stunned: "Are you crazy?" ”

Uncle Quan shook his head, put his body against the wall, and slowly leaned inside, a few of us followed, Xiao Qi saw that there was no way, so he could only lean over reluctantly.

The suction behind the waterfall is very large, walking on the edge of the wall, there is always a force pulling you into the waterfall, I grabbed the wall tightly with my hands, it is estimated that the nails are scratched, the body leans back, and can only be sucked into the waterfall, into the pot was sucked into the waterfall The consequences are unimaginable.

Although this section of the distance was only less than five meters away, it took us nearly twenty minutes to reach the nearest chain safely, and Xiao Jiu was almost sucked in halfway, Qi Gongming pulled him before he barely walked over. Leaning on the chain, you can feel a cold air, this giant chain is indeed very suitable for climbing, the gap between the chains is enough to stand on a person, I reached out and grabbed a chain, ready to climb up, there was a random stinging cold, I didn't have any defense, let go of my hand suddenly, my back hit the wall, a rebound bowed to the waterfall, was pulled by Quan Juncai, almost sucked into the waterfall, I was still shocked, there was a laugh around me, Qi Gongming sneered, I don't know where he came from, and I couldn't help but feel angry when he looked at me and laughed at me.

I did think that this chain would be very cold, after all, it was in this environment, but I didn't expect it to reach this level. Uncle Quan frowned, pressed his hand on the chain, and the other foot also stepped on the chain, and when he picked up this hand again, I heard a "silk" sound, as if a layer of skin was stuck to it, Quan Juncai gritted his teeth and endured the severe pain, three times five divided by two jumped on our heads, a few of us also took a deep breath, and climbed up hard, during this period, two people above me always let out "Ah! Yes! My hand was severely mutilated.

The waterfall was about eleven or twelve meters high, but we jumped up in less than a minute, stretched out our palms, and they were already red, and my palms even bled a little.

But fortunately we didn't fall down, above the waterfall, there is a thirty centimeter wide stone slab beside us, left and right across the entire waterfall, we immediately jumped up, to the side, smoothly to the end of the water, but fortunately, someone here has carved out a plank road, although it is very narrow, but can allow one person to pass, the edge of the plank road is made of stone slabs of guardrails, there are obvious traces of chiseling, on the other side is a towering wall, still smooth, and on our heads, There is a wide slab that spans the entire length of the water, about five meters wide, and looking ahead, there are about three of these slabs, and one more at the back.

We walked from the plank road in the opposite direction of the current, the current here is obviously weaker, the water surface is very calm, the sound is not very loud, the further we go, the quieter the sound.
