Chapter 8 7. Some clues

The vitrification of rocks generally occurs after volcanic lava flows react with rocks, requiring very high temperatures, and violent explosions and incineration can also cause such phenomena to occur.Wang Sichuan's deduction is basically correct, but whether it was an explosion or an incineration remains to be verified.Wang Sichuan’s first thought was an explosion, because the Japanese might want to close the cave before leaving. The general army’s method is to blast the mountain. However, if the yellow explosives at that time were to achieve this effect, the amount must be quite large. After the explosion, half of the mountain may be torn off.Personally, I think it's a long burn, because if there was a big bang here, the hole must not be what it is now.

If it was burned, the hole should have been burned continuously for more than 40 hours. I don't know what they burned at that time. We waded through the cave twice and found that the depth of the underground river was uneven. One foot was deep and the other was shallow. There were pebbles underneath. We could see many small fish in the water with a flashlight.If it is changed to the south, this is definitely a good place to escape the summer heat.It's a pity that it's too cold in the north, and it's a bit bit bitter to wear rubber shoes. The people above hanged down one by one. I also know people from other groups. They passed cigarettes to each other and discussed the situation in the cave. The engineers were doing the specific work. Moved to the raft.

During this period, we also talked about the Japanese soldiers. In those years, there were often rumors that the remnants of Japanese soldiers who were caught in the mountains and had no time to retreat, some of them were already like savages.They didn't know the end of World War II, and thought they were still fighting. They didn't know if there was any in this cave. It would be interesting if such a thing happened. Two hours later, all the crew went down, and the eight rafts were all inflated and floated on the water. Everyone was a little nervous, some people kept talking nervously, and the whole cave was very noisy. At this time, the colonel was also hanged, and he changed into field clothes. Only then did I recognize that this person turned out to be The instructor during my military training, but apparently he no longer recognizes me.

The colonel made a mobilization for us, generally paying attention to safety, and then whether we have the confidence to complete the task and so on. We all said yes reflexively!Then he announced the departure, we each took a deep breath, put on our raincoats, and got on the raft, even if we were officially about to set off. According to the analysis on the geological imaging photos, the place where the plane is located is in a certain section of this underground river, but the vertical distance we explored is not equal to the actual distance. It is much longer than twelve hundred meters. We are the second group. One minute after the two rafts of the first group were pushed down into the cave downstream, we also set off. The engineers in front turned on the boat lights to clear the way for us. The raft hit the cave wall.

Soon, the surrounding sounds were gathered because of the narrowing of the hole, and the light shrank to the surrounding area of ​​the raft.At this time, if you use a flashlight to shine in the water, you can find that the water is already quite deep. This is the characteristic of the structural cave, and the change of the cave potential is very sudden and huge. The hole is not wide, it is only about ten meters here, but it is quite high, and the top of the crack cannot be seen. It makes people feel that they are in a narrow canyon. When the flashlight shines on it, you can also see the root system of the plants.

This kind of scenery is still very spectacular, we were all stunned for a moment, and Chen Luohu even took out his camera and took two pictures with a magnesium flash. After drifting forward for less than 30 meters, a fork hole appeared. After we gathered here, we each drifted into a fork hole separately, and only then did we really enter the tense place.When it comes to spelunking, a team of fifty people feels completely different than a team of five. We drop a few radio buoys so that if there is a problem ahead, the signal will be distorted and we can give an early warning. But the water flow is very slow, watching the buoy with light bulbs slowly float to the front, we followed up with confidence.

The dangers of cave exploration are often exaggerated in novels. In fact, as long as you follow the procedures and be cautious, cave exploration is relatively safe. The main danger is that the rock is unstable, and the cave collapses after people enter, causing casualties.At this time, all the engineers in front were holding their guns tightly, which made us feel very funny. However, without the experience we have accumulated over the years, it is understandable that it is difficult for people not to be nervous when seeing the darkness in front of the cave. In the first four hours, everything went well. We quickly drifted more than 2,000 meters in, and the current began to rush, and short waterfalls like turns and steps appeared.Because there are large piles of rocks under the water here, and some things stuck in the cracks of the rocks are beginning to appear around them. They are all things left by the Japanese in those days, such as wooden boxes and rusty cans full of holes. Some vague numbers, we can't read Japanese, don't know what it means.

Just when our attention was attracted by these things, we encountered the first obstacle. The boat in front stopped suddenly, as if it was caught by something, and then our boat bumped into it at once. The person almost fell into the water.Then our boat turned head to tail with the current and huddled with them. We all find it strange that we can't see anything on the water, but the two boats are here, and they stopped abruptly. Is there something under the water? We stirred in the water with our oars, and we bumped into an obstacle. With a vigorous push, we actually picked up a ball of barbed wire from the water.

"You little Japanese, you even gave me a hidden stake." The deputy squad leader cursed, and sent two engineering soldiers into the water to cut it off. The two soldiers immediately took off their clothes and jumped into the water, biting their flashlights and diving into the bottom of the water, the water was splashed with ice cold, which made us all shiver.I really admire their courage to jump as they say. Unexpectedly, within three seconds of going down, both of them floated up. The squad leader asked them what was wrong, and one person tremblingly said, "Report to the squad leader, there is a dead person hanging underwater."
