I stood still, not fiddling, but the uneasiness in my heart had already come to my head. What's going on right now? I've seen it, the vents of diving equipment, the bubbles after the carbon dioxide is expelled, and those bubbles come to the surface, that's what it looks like.

"Panic what, a few bubbles can't kill you, stand still." I don't know what's going on, although I have tried my best to restrain myself, but the obvious uneasiness was still noticed by Jiang Huai, but he didn't give me a little face, which made me take two or three steps back.

"Don't, they probably have guns, I don't know if there are heavy weapons underwater, but there are so many equipment tents, and some of them haven't been affected by the explosion, don't do it, although I know you're all awesome, but you can't use cotton to block stones." I persuaded after the good words, but what I got back was a sneer on Jiang Huai's face.

He turned his head again, and the person leaned against me and listened to him: "The question of life is still to be considered, don't keep running for the goal, you don't know how to die, those things are not someone coming, but someone is leaving." ”

Jiang Huai was a little impatient with this, and he walked around in place a few times or spoke, at first, I really didn't understand what he meant, but I walked a few steps forward and saw the black and clear water, and then I figured out the problem.

Limitations and focusing only on the immediate problem are fatal problems for my current situation, and I simply think about what I can think of, and relate to Huang Can, who threatens us, but forget some of the more important keys.

That is the structure of the place, this place must have had no water before it was dug up and collapsed by the cult leader Li Niu'er, and the water was poured into the mountain full of dense holes after the collapse, so a relatively ordinary physical phenomenon was produced, that is, water could not be poured into some closed cavities at the top because the air in the holes could not be poured into some closed cavities at the top, and the water pressure and air pressure were balancing each other.

We were in the same position as we had imagined, because the water hole was airtight, and the gas was compressed by the water, but it could not be completely squeezed out, so there was a hole left that was not completely submerged by the water.

The rest of the places are even close to us, and there may be similar structures, and it is because of these special structures that we have any hope of survival, one is because we have no oxygen equipment, we are in the water, there is no light source, which is a very dangerous behavior, and we have to search for no oxygen, and the time it takes is simply not to estimate. Nowadays, it seems that the food problem has been solved, and the water can be evaporated with salt water, but the only problem is that it cannot be moved, so it is precisely because of these water holes that we do not know the specific number and specific location that the only way for us to move and escape.

I figured it out, but I still glanced at Jiang Huai with some confidence, and waited for a long time before I asked: "According to this, there is someone out of the hole and dives down, and the bubbles are coming up all the way from elsewhere?" Hiss...... In this way, we are at least connected to the other side here, otherwise the bubbles will not be able to come up. ”

"Just understand, get ready, we're going to go into the water." Jiang Huai responded to me, and began to look for things in this less than ten square meters of place, in fact, it was preparation, and we didn't have much to prepare, at this time, I was naked, I couldn't find half of the fabric, and the ground was also a messy human skeleton, and it was estimated that it might be the survivors after the collapse of the mountain at that time, but the rapid influx of water blocked their way of life and trapped them here.

"How far is the nearest water hole to us?" I saw that half of Jiang Huai's body had stepped into the water, and the difference between the bottom of the water was very large, and Jiang Huai had almost submerged half of him when he went down.

"Seven hundred meters." Jiang Huai didn't hesitate and blurted out, after he finished speaking, he had already dived his whole body into the water, only exposing one head outside. After the others went down, the water level rose instantly, and a series of bubbles emerged from the water.

Like him, I found that there was really no other way to dive into the water, and the water was very cold, and the difference between the temperature in the cave was at least ten or twenty degrees.

We don't have a light source, even if we know water, then I don't dare to come down casually, now I can only follow Jiang Huai in front of me, touch each other's ankles and swim forward.

It's really hard to say that water-based is a thing, I used to learn it specifically, and I only stayed at the point of half-bakedness, but in the past few days, although I haven't focused on it a few times, it has improved a lot.

In the dark, just holding our breath, we groped the walls of the cave, but it wasn't really exactly 700 meters before there was oxygen supply. In the middle section, I understood what Jiang Huai meant, he said 700 meters, that is the destination location of a stage, similar to the place where we rested, there are naturally some cavitated water holes, we can only be submerged in the water, but oxygen can still be replenished.

I can't estimate the exact distance or time, but after about a dozen cavitations, we finally climbed to the hard rocky land.

I gasped, Jiang Huai was not much better than me, the situation in the cave was unknown, and it was no longer enough to describe this kind of blackness when I couldn't see my five fingers. I then asked, and after waiting in the dark for a long time, I didn't hear Jiang Huai's voice, and his wheezing seemed to disappear suddenly.

When I reached out and grabbed nothing, my heart was just groaning, why was the person gone? I shouted again in the black hole, and the echo was very loud, this cave chamber is not small. Just as I was thinking about whether to move away from my original position, I suddenly saw a bright light in the water in front of me.

The surface of the water can finally be seen clearly, but the light and shadow under the surface of the water are really uncomfortable to see. I didn't continue the previous movements, I still stayed in place, and now the light coming out of the water is getting closer and closer, the halo is not very natural, and when the water explodes, Jiang Huai shows his face, I realize that I have made the right bet.

Jiang Huai was holding a strange fish in his hand, that kind of fish was the same kind that I had eaten before, but the body of this live fish was glowing pale green.

The live fish is almost an arm's length of mine, and it is three or four times larger than the previous one. The pale green light emitted by the fish body did not have much penetrating power, and the whole light and shadow sprinkled on Jiang Huai's face reflected his incomparably hideous.

"It's a bit contradictory that a blind fish in a lightless environment will glow on its own." I leaned on the rock to make room for Jiang Huai, Jiang Huai climbed on the water, the fish was put aside by him, I looked at the glowing fish body, the translucent feeling became more obvious, the light source of this fish is not its skin, the green light penetrates from the almost transparent flesh, although I can't see clearly, but I still feel that the light source is actually in the internal organs of the fish.

"It's crystal sand, there is crystal sand ore at the bottom of the water hole, these fish can't see the sun, and some of the necessary ingredients that need sunlight and hormone synthesis in the body can't be obtained by themselves, so they can only eat these things to supplement. Mingjing sand, in fact, is a kind of night pearl rough stone, the darker it is, the brighter it is, as long as there is a little light source, its color is difficult to see, don't be surprised, this kind of thing is very common, there is a kind of light-sensitive material seems to be extracted from this kind of thing. ”

I didn't reply again, and now I'm depressed, thanks to which I wasn't hungry at the time, otherwise if I had eaten the entrails of the fish, I wouldn't have needed to bring a flashlight when I went out at night.

The live fish was made into a torch by us, in fact, we found a thigh bone and inserted it into the body of the fish, there are not many corpses in this hollow, only a few bones can be found scattered, and because there is water on the ground, I didn't ask how the fire was lit, I held the bone in my hand, and walked into the depths of the cave in a few steps.

The air-closed cave here is several times larger than the previous one, but the water surface is slightly higher, and it is already full of rocks, and the water on the ground is not good to sit and rest, so you can only explore and explore.

According to the traces on the cave wall, the excavation process of high temperature roasting and water collapse is no longer used here, and that method can not be used in this place, more than 100 years ago, the deep mine mining is basically mature, but for the installation of air supply and exhaust devices in the mine, this will definitely not be done, the cost required is much higher than the amount of excavation for several months, ordinary mines are like this, far away in the mountains there is no meaningful excavation of economic value at all, and naturally no one will arrange it.

In fact, it can be inferred that most of the people who die in the cave will probably not die in other ways. Oxygen is the Achilles' heel of the deep cave, this kind of cave is different from the natural mountain fissures, can only rely on the excavation workers themselves to carry the head, so the high-temperature furnace used to roast the rock must not be used here, the cave is smooth, the ground can not be seen, and there are vertical lines on the top of the head, seeing these phenomena, I understand, the rock is hard to chisel with a chisel, and the people who develop here are not stupid, with the help of the structural advantages of laminated rock and basalt, this road is also considered to save labor.

This discovery also gave me an understanding of the basic structure of the entire complex network of caves, because of the basic structure of laminated rock and basalt, it is impossible to excavate diagonally, so most of the huge man-made cave systems we will face are horizontal and vertical straight routes. This is very important, not understanding the structure here is a big flaw for us, although we don't know the specific direction, but knowing what logic the other party is based on, maybe we can still rely on simple reasoning to enumerate.

I was about to continue walking, when Jiang Huai suddenly grabbed the leg bone in my hand. The strange fish erected above is already dying because the leg bones go straight through the body, but fortunately, the light source has little to do with the life or death of the fish.

I turned my head to look at Jiang Huai behind me, and he grabbed my leg bone and pulled me back with me. Seeing Jiang Huai now, he was half facing the cave wall, I didn't pay attention there, but there were some traces that seemed to be left by the chisel, at this time it was pulled closer, and the light was a little brighter, and I saw some patterns on the cave wall that didn't look very random.
