I was not asking for their opinions, but telling them what I had to do, so I didn't wait for Big Eye and Zhang Ling to respond before I dived into the water again.
Entering the cave, I can clearly feel the pressure of the surrounding water on my body. I feel like a swimming fish, walking in a unique way in the long and narrow corridor under the water. Five meters away is dark, and everything is shrouded in mystery. Veil.
It was extremely quiet in the dark, as if escaping into the void.
The passage is in the shape of a rugby ball with two pointed ends. Whether you look up or down, the lights are swallowed by the merciless darkness.
Suddenly, I felt that I was swimming towards the underworld, and the darkness was stretched out, going up through the sky, down to the abyss, floating in the air, like a dust before the endless darkness. The rock walls around me also shocked my vision from time to time. Occasionally, the light beam swept through, and I saw a big mouth cracked in the rock wall, dark and bottomless inside.
There is also a rock wall that highlights a face that looks like a monster, with a nose and eyes, and I was surprised to see it at close range. The torrent behind him was pushing him all the time, and the rope in his hand couldn't be loosened for a moment.
Three or forty meters in the cave, I used a searchlight to shine forward, and found that there were four or five dark holes on the right and in front. I was stunned for a moment, and then I swam over.
Soon I discovered that I seemed to be inside a huge sponge. There were cracks and openings everywhere, and the holes were connected, layered on top of each other. The whole route of advancement was shuttled up and down in the sponge with ropes. The internal structure was very good. complex.
Turning around, I noticed the gravel in the cave again. To be precise, it should be similar to a giant rock, stacked like a chimney to form a circular channel, but the edges and corners of the rock are all branched to the inside of the channel.
One side of the stone is irregularly pentagonal, hexagonal or octagonal, which looks more like undulating serpentine armor, which makes people start to suspect that these complex structures are not natural, but artificial.
But who made it? Is it also the person who made the Crystal Palace
If it is really made by humans, it is not difficult to imagine that building such an artificial passage at a depth of tens of meters under the water will last for thousands of years. It is a huge project at any time. Moreover, these strip stones are so huge, how did the ancients
Why pile them up
Going forward in the channel for about 70 or 80 meters, the inner diameter of the channel seems to be smaller, and the flow rate and pressure of the water have increased significantly. It is necessary to hold the main rope firmly to contend with the powerful current.
I can still feel the constant friction between the body and the inner diameter of the channel, especially the oxygen cylinder on the back. I try to keep my body's center of gravity down as much as possible. If the oxygen cylinder hose is broken by those rugged stones, and it gets stuck in a place where I can't go up and down, I can only be suffocated.
At this moment, a huge thrust suddenly came from behind me, followed by my body hanging in the air, being punched by the water, and falling heavily like someone squeezed myself down with a huge fly swatter.
All this happened suddenly and caught people off guard!
With a sound, I was like being washed into another canal from the sewer, and fell heavily into the underground river.
From the bottoming feeling of falling and sinking, I knew that I had entered another underground river. The depth of this underground river was not more than five meters, but the water surface was estimated to be wider because the flow rate of the water was significantly slower.
The huge momentum caused me to flip twice in the water. After regaining my center of gravity and sense of direction, I untied the rope around my waist, took off the oxygen mask, and exhaled. I felt refreshed and happy. I couldn't help but sigh the fresh air here. .
After I didn’t swim very far, the soles of my feet were on the ground. I got up wet from the water and started to observe the surrounding situation with the searchlight. As my eyes turned, the beam of the headlight slowly moved, forming a bright light in the dark. The band of light finally gathers on the wall and becomes a spot of light.
With this method similar to peeping a leopard in a tube, he carefully looked at this completely unfamiliar environment.
This is a lava cave with a width of about five meters, a height of ten meters, a flat bottom and top, and an ampulla. The water level line is not visible. The inner wall of the cave is slippery and smooth. The overall impression is more like A fully constructed tunnel.
And I stood at the entrance of this tunnel. The front and the top of my head were unfathomable, with only a cloud of pitch black; behind me was the entrance of the river, or the source of this underground river, it was like a diameter A tap water pipe of about sixty centimeters can't help pouring the rushing river water into this tunnel from mid-air.
Beside the main pipe, there is another small water outlet, which forms a very strange
The special roots waterfall is like an old tree growing on the edge of a cliff. Numerous roots stretch out from the cracks of the cliff and hang in the air.
The headlights shone over, and the white flowers were as thin as silver threads, not like water, but more like quicksand.
For thousands of years, the pouring torrents rushed out of a big pit in front of the water pipe, and then, these waters gathered slowly, jubilantly, and flowed into the dark depths.
Staring at the surface of the river, the light couldn't shine into the river unexpectedly, and the satin-like water surface was slightly undulating, and the horizontal waves were thousands of hills, as if it had solidified into black colored glaze. The black river and the black rock joined together, seeming to be infinite and far-reaching.
Everything is like a strange dream.
This is a world belonging to the underground, a miracle cast in the dark. This is the handwriting of nature. It is like a tireless coal digger, with a time limit of hundreds of millions of years, and then carefully cover it with darkness, with The water of life is meticulously cared for, so that people will not discover it.
When you stand at the source of this underground river and look up, you will think that there is a huge mountain above your head. Looking far away, there is endless darkness. How many secrets are hidden in the darkness, only for people to imagine and guess. .
At this moment, two "plops" sounded behind me. I hurriedly looked back and found that Zhang Ling and Big Eye had been washed down from where I came out.
They actually followed.
Big Eye and Zhang Ling flopped and swam over, and I asked loudly, "Why are you here too?"
Big eyes took off the oxygen mask, stood up from the water and said: "We have been waiting for you for half an hour. Seeing that you haven't come back, I'm afraid that you may encounter an accident, so we will come down and have a look.
I actually stayed in the cave for more than half an hour. I stayed in the cave for half an hour while watching and walking, so I walked slowly. They came directly down to look for me, which naturally took a short time.
When I talked about the situation here, Zhang Ling immediately suggested: "Let's go ahead and take a look."
I nodded, then looked back at the entrance. It was seven or eight meters high from the ground, and they had brought the rope to it. If they wanted to go back, it would be impossible.
The three men began to explore the depths of this underground river. After about five hundred steps, the sound of water at the entrance gradually became quieter. Instead, some cold water dripped down the top wall into the river, making a crisp "tick" sound, but the darkness remained, and the road ahead seemed endless. .
