There was nothing to say all night, and soon it was five o'clock in the morning the next day. Brother Xiao woke us up from sleep room to room.

I don't have any idea about time. Young people, who doesn't like to sleep until they wake up naturally? Therefore, when I was woken up by Brother Xiao, I still couldn't open my eyes. But soon you get full of energy, and as for why this change is happening, I think you will have this reaction when you see a big beautiful woman walking in front of you in a looming pajamas.

Without further ado, after our group brought all the equipment. Taking advantage of the dark sky, he directly touched the Qinglong Pond. Since it is almost May now, on the way we came, the cries of various insects and frogs came and went, and if you are a timid person, walking alone in such a sparsely populated place, listening to the sound of insects, you will probably be scared to pee your pants.

But, alas, each of us is not only bold enough. Usually walking alone and walking at night is not a problem. Touching a dead body is called pediatrics, do you think it will be scary to walk at night?

So, after arriving at the edge of Qinglong Pond. Everyone began to put on wetsuits, oxygen tanks, and diving goggles. Wrap the backpack in a waterproof bag and carry it on your back. Holding a waterproof searchlight in his hand, he looked at each other and nodded. Immediately, the group began to dive to the bottom of the water, swimming towards the collapsed mountain rocks and the exposed hole.

Yesterday I couldn't see what the entrance of the cave looked like, but now with searchlights and goggles, our field of vision has suddenly expanded from more than two meters to ten meters.

The passage is wide and high. This is our first impression after swimming along the passage for a short while. Its width is not much different from the opening, about three or four meters. With such a wide spacing, the three of us traveled side by side in a row, and we didn't feel crowded at all.

As for the height of the passage, I have visually measured it at least ten meters. As we looked up, by the light of the searchlight, we could barely see the top of the passage.

After swimming a little further, I came to a second conclusion about this passage. It's just quite long. We've been swimming for at least a few minutes, and we haven't reached the end of the swim yet. I really don't know where the end of the pool of the green dragon pond is. Swimming in this passage is like diving in various reefs in the sea.

Of course, at least this scenery can't be compared to the bottom of the sea. Although the bottom of the sea is full of dangers, the scenery is also quite tempting, with a variety of underwater flora and fauna, which will make you addicted. On the other hand, in this passage, except for the rocky walls on both sides, there is not even a small fish. I really don't know why Dào's water area is so spacious that it can't adapt to the growth of flora and fauna in the water.

After about ten minutes of swimming along the wide passage, we finally came to the end of the passage.

Originally, we thought that the end of the passage was the source of the water in Qinglong Pond. But we were a little wrong.

Because the end of the passage is like an ordinary mountain and rock cliff. In other words, it's a dead end, and there's no hole at all.

Are we wrong? Is this just a passage with a cave? Is it possible?

No way! With so many things in front of you, is it just to disguise that there is a nearly one-kilometre-long passage here?

If you say that, no one will believe it. So, we saw the end of the passage and were stunned for a moment. It is to start looking for other clues at the end of the passage. Maybe the clue is on the cliff at the end of the passage, or maybe it's in the place where we have passed before.

To be honest, I hate this kind of mechanical design. It's too much of a test of people's eyesight and intelligence. As long as there is a slight difference, then you are basically out. Of course, I think the designers of the mechanism would be happy to see this. After all, the more we intruders, the more we hate it, the more we can't do anything about these mechanism designs, and it can also reflect the power and cleverness of the mechanism designers.

Think about it, if you're a mechanism designer. Someone has broken into your mechanism, and after a long time of seeing your mechanism, they stand there helplessly. How would you feel as a mechanism designer?

After fumbling for a while, I felt a little sad. The truth seems to be a little far from what I thought, because we didn't find anything like this at all. Doesn't that mean that we have been busy for so long and have purchased so much equipment, but in the end it has been a failure?

Just as I stood there in confusion, looking at the empty passageway. Suddenly I felt someone tap me on the shoulder.

I turned to look at the figure who patted me on the shoulder, and judging from her figure, she was undoubtedly Lin Yuxi. After all, her body is the smallest among us, so you can naturally recognize who she is at a glance.

"What should I have done?" Seeing that I was a little stunned, Lin Yuxi stretched out his finger and pointed to the sky above me, and then kept gesturing with both hands!

After getting along for so long, I instantly understood what Lin Yuxi wanted to express from Lin Yuxi's movements. That's what she's telling me that there should be some clues in the sky above me, because she's sending the water from the top down. Therefore, she determined that the source was most likely above.

Top? I looked up confused. Could it be the source of the Blue Dragon Pond? Isn't it, don't you know dào if you swim up!

With that in mind, I swam up towards the end of the passage. Lin Yuxi followed closely behind me, and when Brother Xiao and the others saw this, they didn't say a word, but they also followed. The six of them are like six big fish, swimming against the current with a graceful swimming style.

Yes, we can't quite feel the direction of the water when we're down there. But the further we go upstream, the stronger the resistance we feel. Anyone who swims in the river knows dào, that is, the feeling of swimming against the current.

That is, we now carry special diving equipment. If we hadn't brought professional diving equipment, we would probably have been planted in this passage this time. Therefore, it is not unreasonable for the ancients to say that they should take precautions. Everything must be done accurately, so that you can get twice the result with half the effort.

The feeling of swimming against the current is really difficult. But that doesn't stop us from moving forward. After all, we carry oxygen tanks on our backs, which can allow people to dive underwater for an hour without coming to the surface. Here, let's say that high-tech production still has its own absolute advantages. Otherwise, those scientists would not have engaged in all kinds of scientific research under the pretense that they are gods on this planet.

As I told you earlier, the height of the passage is about 10 meters. But who would have thought that we would swim against the water flow at the end of the passage and swim straight for more than ten meters without being able to see the source of the water source of Qinglong Pond. Strange, you say, isn't it?

Finally, after a distance of five meters further upstream. I suddenly felt the pressure on my body lighten, as if I had carried dozens of pounds of something and someone helped me remove it from my back.

I haven't figured out what's going on yet. After swimming for a short time, suddenly his head was out of the water. Yes, as some dripping bells appeared in my field of vision, I was shocked that I had already swam to the surface of the water.

I am not the only one who has this abnormality, following Lin Yuxi, Brother Xiao and them behind me, everyone is stepping on the water, and they are looking left and right in disbelief in the water.

It is an empty cave with many waterholes of various sizes. To be honest, I don't know how broad it is, because when I look at it, I feel that everywhere can be extended to other places. On the perimeter of the waterhole, there are many cracks, where many columns of water with different currents continue to flow into the waterhole from the outside. It turns out that this is a hole in the sky, a waterhole in a waterhole?

As for such a strange phenomenon, I don't know if it is man-made or a masterpiece of nature. First, the water from the outside flows in, and after filling the waterhole here, the rest of the water directly fills the passage that connects the waterhole we are in. How long will it take for that condition to form?

Taking off my goggles, I swam some distance to the edge of the waterhole, and I came directly to the edge of the rock. There is a road here that is not considered a road, and judging by the direction of its extension, it should be quite long. I just don't know where the end of the dào is.

After going ashore, everyone took off their goggles and turned off the oxygen tank. After all, the air here is very fresh now, and we don't need to waste the oxygen in the oxygen tank, and we will probably have to use it when we go out.

When the thin man came ashore, he looked around for a moment the environment we were in. Full of disbelief, he said, "I'll go, who can sue me, where is this?"

"Depending on the depth of our dive, and the altitude of the swimmer at the end of the channel. I estimate that our current position should be more than ten meters above the shore of Qinglong Pond. ”

Lin Yuxi stroked his long wet hair while answering the thin man's question. It's really tempting to watch the action of brushing his hair.

"That's right! If I'm not mistaken, we should be inside those mountains not far from Qinglong Pond now. As for why it's connected, I think it's artificial!"

"Artificial? Wouldn't it?"

Not to mention that the thin man didn't believe it, even I couldn't accept it at first. But that's the way it is, I can't believe it, and I can't believe it.

After reading the design here, I suddenly realized that my knowledge was being challenged. Why do I say that? It's just because I said earlier that all other places in Qinglong Pond are dead places, and only the bottom of the pool can be regarded as a treasure of feng shui.

But it didn't even occur to me that these things could be changed.

Maybe you don't understand what I mean. This doesn't matter, let me explain it slowly, and everyone will understand.
