Her words made me feel a little different, but I didn't care what she said, and I just paused for a moment and moved on. The edge of the pit was already full of people at this time. It seems that there is not only one person who has just gone down, but there is also one who accompanied him, and only forty people have made it up. The other one was just a fluke. Despite this, he didn't know what he saw, and now his eyes were glazed over, and he didn't answer anything. It seems to have been stupid.

In the army, meritorious service can be promoted. That's why the two of them took the risk. But after all this, no one wants to go down and take any more risks. Looks like I'm going to have to go down on my own.

Gear up and bring your backpack. I got into the iron cage by myself. This time the lines with limited equipment have been re-added, and it should be possible to go further. In fact, only I know that if I gather forty people, if I go down in the future, the danger will be much smaller. But no one wants to go down, so I'll go down on my own and explore the way first. The iron cage descended slowly. Soon it was at the bottom of the cave again. I continued along the same route as I had done to the fork on the right side of the stone corridor. I walked for another half hour or so. I reached the end of this stone corridor, and it is not accurate to say that it is the end, because there is a small hole in the back wall, which should accommodate a person to climb into, and behind this small hole that is more than thirty centimeters old is a wider space. It's like a passage carved out of the wall.

I shone a flashlight inside, but the light from the flashlight was too concentrated, and it was just a band of light. I lay on the ground and looked at it for a long time, but I didn't find anything. A few glow sticks were thrown in, probably because the space was too large, and the scope of this light was very limited. It was as if swallowed up by the endless darkness, and only the outlines of a few glowsticks could be seen. It seems that if you want to find out what is going on inside, you have to go in yourself, but the problem is that this hole can only accommodate one person to climb into, and I can't get in with an oxygen tank on my back. I reported this to the ground. The ground command also seems to be in a difficult position. I'm not going to go back and figure out what they say, the most straightforward thing is to take off the oxygen equipment.

I decisively took off my oxygen gear and took a deep breath. I found that the oxygen content here was enough to breathe, not as bad as I thought. Now I can finally rest assured. I stuffed the bag of gear into the hole and slowly climbed into it myself. As soon as I entered, I felt that the space was very spacious and there was no feeling of humidity. I took out a flare from my backpack and shot it high into the air, and sure enough, under the strong white light, I could see the whole picture of the cave, which turned out to be a man-made cave, and the cave was hexagonal. There are six walls, each with many symbols carved on them. The cave is about 300 meters high, and the higher you go, the smaller the space becomes, like a cone. When I saw the foot, I suddenly found that this pattern was very familiar, isn't this the style of the Bagua map? I took out the guide and looked at the directions, and found that there were no stone walls in the north and south directions, and there were in the other six directions. It's just that why there are only six sides that I don't understand at all? I quickly took out a pencil and paper and briefly sketched the situation on paper. There were four flares in total, and by the time they were all fired, they were almost finished. The ground conductor also seemed to see something unusual about the cavern. I asked about the situation, but I couldn't explain it, I just told them to quickly find someone who knew gossip maps.

I followed the light of my flashlight and headlamp and looked around, but I couldn't find any other passages. No clues were found related to the missing persons. It seems that we can only hope for the passage on the left.

I climbed out of this cave and returned to the stone corridor. Follow the same path back to the fork in the road. Walking towards the passage on the left, the passage on the left is obviously much narrower, and the narrower the place, you can clearly feel the wind, which indicates that this hole is not just an entrance to the sinkhole that suddenly collapsed, there should be other exits. It is not difficult to explain why the air inside can breathe normally, and if it is a pit at this depth, it should deposit a lot of heavier gases, especially carbon dioxide. If this is the case, then there is no hope of survival for the forty people who fell.

Walking along the passage on the left for about twenty minutes, the footsteps became heavier and heavier, because the lines of the wired communication equipment carried were too long, and the stone corridor on the left was winding, so the walk became heavier and heavier. At this moment, suddenly the light above my head went out, and I was instantly plunged into darkness, and my heart began to pound. I thought something terrible was going to happen, but after waiting for a long time, there was no movement, and it seemed that it was down many times, and the battery of the headlamp was dead. I turned on the flashlight and continued to move forward, but the flashlight is not a big one, just a general household use, because the light is too big to carry and very heavy, and carries a lot of lighting equipment, this flashlight is just a spare item. I didn't expect it to come in handy now, but it's a pity that the light can't compare to the headlamp.

After dragging his heavy footsteps for a long time, the road in front of him became wider and wider, and then he entered a grotto, but this grotto was not as beautiful as the one just now. Looking at the stone walls around you, it seems to be naturally formed. This is a little strange, the same fork in the road, why the left and right sides of the cave so big difference. But now there are no flares, and there is no way to see the whole cave. I turned the last few glowsticks out in all directions, and to see how far the glowsticks were thrown, the hole was much larger than the one I had just thrown. And it's irregular, because in some directions, the glow sticks hit the stone wall and fell to the ground, while others didn't even shine the shadow of the stone wall. At this point, there are five or six luminous dots fanning outwards from my point.

I walked over to each of the glowing spots, taking a general look at the cave. One side reported the discovery to the ground. At this time, the people on the ground changed from the original grief to anticipation, and most of the families of the victims had already received the news that the family might survive, knowing that there was air circulation in the hole, and there was no sign of falling to death.

I looked around the hole, and as I made my way towards the area illuminated by the fourth glowstick, I accidentally tripped over something. It feels soft, not stone. After getting up, I quickly took a flashlight and shone it, and it was actually a person, lying sideways where I passed. Luckily, I walked slowly and didn't fall very badly. The flashlight was not broken, and if the flashlight was broken, it would be difficult to go back. I quickly reported my findings to the ground, who instructed me to check for vital signs. Is there anyone else, I took a flashlight and looked around, and found that there were a lot of people lying around, and they were all breathing. The ground commander, who received the news, immediately told the family members who were waiting for rescue. But I can't bring them back to the surface alone. And there's a problem that they can't wake up no matter how much they are called. So the ground commander asked me to return immediately and take a few more people down, because they were afraid that if they did not lead me, they would be in danger if they came down on their own. I followed the instructions and started to go back the way I came.
