Xiao Lei took out the rope from his bag, and then tied it to the pine tree, just wanted to be the first to climb up, but the "monkey eagle" screamed a few times, and the old man Ouyang hurriedly said: "The 'monkey eagle' wants to be the first to go in, it is afraid that there is danger inside." ”

Before we could say anything, the "monkey eagle" flapped its wings and flew in, which made us all moved, what a bird with affection and righteousness.

We also followed closely and climbed into the cave along the rope, the beginning of the cave entrance was so narrow that it could only accommodate one person, but after climbing more than ten meters inside, the space in the cave suddenly became larger, and after people stood up, their heads could not touch the top of the cave. We felt very relieved to have a "monkey eagle" in front of us to clear the way.

Maniac Six said to everyone, we can find the exit so quickly, the Japanese and the high blind may not be able to predict it, and we now have the "monkey eagle" yang protection, its effect will not be worse than the human face worm, the high blind man's mind reading skills, it is difficult to play a role, and the high blind man's meridians are in the weakest period, and his various super abilities will be greatly weakened. So, the sooner it is for us, the better.

What makes us even happier is that there is only one tunnel in this cave, and there is not even a fork in the road, so we can just go ahead.

And this kind of cave, we are very familiar with walking, because it is similar to the cave in the cliff, it is spiral-shaped, although the cave is very dark, but the ventilation is not bad, walking in it, there is a cool breeze feeling, and there is no fishy smell of amphibians.

Although we don't know how long it will take to get out, our hearts are still full of hope, and we feel that as long as we keep going up, we will definitely be able to get out.

But after walking for about forty minutes, the cave suddenly changed, no longer spiraling, but becoming horizontal, I really didn't expect that there is such a level of cave in this mountain! And even the ground became smooth, and not only that, but the tunnel was straight, and there was not a single bend.

Seeing such a tunnel, all of us were shocked - this is certainly not a natural formation, but an artificial construction, but who can have the ability to build such a large-scale tunnel in the mountain, the work is incredible.

Walking in this flat and straight cave, we have the illusion that we are passing through a long artificial tunnel, and at the end of the tunnel, there may be bright sunlight.

But what we didn't expect was that this straight tunnel was so long, and we walked for about half an hour, and when we used a flashlight to shine it, we still couldn't see the end.

Where does this lead? God, it's unimaginable.

As I continued to walk forward, a bend suddenly appeared in the straight tunnel, and this bend was almost a standard 90 degrees. Could this be an abandoned military project? Or is it the tomb of an ancient emperor?

However, before we got out of the cave, we didn't have the heart to discuss these things, and everyone knew that in this dark and mysterious cave, all kinds of dangers could arise at any time.

After turning the corner, the oncoming wind suddenly became much stronger, and from that wind, we seemed to be able to smell the breath outside, which made us feel a burst of excitement in our hearts, and everyone knew that we were almost at the exit.

Sure enough, after turning two more ninety degree bends, a hole appeared in front of us, everyone collected all the flashlights in their hands, and shone on the hole, I just wanted to shout and rush out, but Xiao Lei grabbed me and said, "Slow, you take a closer look at the hole." ”

After Xiao Lei stopped me, I took a closer look and realized that there seemed to be something wrong with the hole - although I couldn't tell what was wrong for a while.

When we walked slowly, we realized that the entrance to the cave was actually on the cliff face! Is there still an abyss beneath this hole?

Because it was a cloudy day, not a single star could be seen in the sky, and the night outside was pitch black, making people feel a little depressed, and they couldn't see the surrounding environment at all.

We used the flashlight to shine outward, trying to see what was around us through the bright light of the flashlight, but the bright light of the flashlight, in the vast mountains, faintly like an oil lamp, except for the vague cliffs in the distance, nothing else could be seen clearly.

"It seems that we can only spend the night at the entrance of the cave, and wait until dawn", Madman Six sighed and said, we looked at our watch, it was just past nine o'clock at night, but Madman Six was right, it was too dark now, and there was hardly anything to see outside, so we could only wait for dawn to talk.

As soon as everyone stopped, all flashlights were immediately extinguished, but the tunnel was very safe - four or five meters in front of it, it was a 90-degree corner, from the corner to the entrance of the cave, like a small cave, and the "Monkey Eagle" stood at that corner. And the ground of the cave is really too flat, I walked in the cave when I looked at the ground, and found that it was all polished and very smooth stone slabs.

Xiao Lei took out the sleeping bag, spread it on the ground, everyone sat on it, although it has not been able to completely get out, but because it is very close to the entrance of the cave, it can already smell the fresh air outside, and there are gusts of cool breeze from time to time, blowing in from outside the cave, which makes us feel a lot more settled.

At this time, there was a dull thunder from time to time, and it seemed that it was going to rain outside.

"This cave is supposed to be a military facility." After Xiao Lei sat down, he sighed and spoke slowly.

"Oh? How do you decide? When Madman Six asked, there was no surprise in his tone, as if he had thought of this.

"Such a large-scale project, if in ancient times, can not be said to be completely impossible, but at least more than 100,000 people, hard work for decades, can be completed, the amount of work should be similar to the construction of a Qin Shi Huang Mausoleum, although I am not very good at history, but as far as I know, in our area, there should be no emperor to build a mausoleum here, and the vassal kings in this area, not to mention this kind of financial and material resources, judging from this point alone, it is impossible to build in ancient times.

In addition, in ancient times, when digging tunnels in the mountains, because there were no explosives, the general use was the 'burning method', that is, first use fire to burn the stone, and then pour cold water on it, so that the stone will peel off and become brittle, and then it is very easy to dig up, but in this way, on the surface of the cave wall, there will be a special trace, I took a serious look at the four walls of the hole, there is no such trace at all, but more like a modern drilling machine, so, this can not be an ancient burial chamber, but is likely to be a modern military facility.

Although it is very difficult and expensive to build military facilities in the mountains, it is of great strategic importance, and in war, such fortifications are extremely powerful and are the strongest military fortresses. But this military facility seems to have been abandoned. ”

This is related to Xiao Lei's profession, so he said it head-to-head.

"Xiao Lei is right, it was abandoned, this should have been built by the Japanese, and it was built in that war decades ago."

The madman sighed and said, although his expression could not be seen in the dark, but that expression must be very painful, every time he talked about that war, he always had that expression, we can all understand, because the most tragic war, he has experienced it himself. However, the conclusion of Crazy Man Six still surprised everyone, because no one could have imagined that there was such a huge military base built by the Japanese in the mountains of this big mountain.

In the darkness, Maniac Six continued: "When fighting the Japanese army in this area, the Chinese troops suffered extremely heavy casualties, and the Japanese devils stationed here at that time really made us feel elusive, for example, you see that he didn't have many troops, and then came to fight him, but he could suddenly "conjure" a lot of troops, and the firepower was even more fierce.

After I took over the intelligence work of this generation, I vaguely felt that the reason why our intelligence was always inaccurate was because there might be a secret base of the Japanese here, so Japan's troops could fluctuate from one to the other, and generally speaking, although the Japanese were very strong in combat, they were not good at fighting guerrilla warfare, especially in this big mountain.

But even our best at guerrilla warfare troops, have suffered the big losses of these Japanese soldiers, the reason why the Japanese devils here are so difficult to fight, is because they have a secret base as a support, the superiors are very supportive of my conjecture, so, I also began to look for the Japanese army's secret base, but I have never found it, and, in the process of searching, I was caught by Inoue, almost killed, fortunately my life is big, it is a blessing in disguise.

Decades ago, I tried my best to find it but couldn't find it, but what I didn't expect was that today I was crooked, but I found it, alas, it's really a creation and a man, if we could find this cave back then, how many fewer people would we have died. ”

The words of Crazy Man Six also made us sigh for a while.

If it's a military installation, there should be a lot of space, and it shouldn't be just this straight tunnel.

Xiao Lei further analyzed that when the Japanese built this fortification, it should be based on natural caves, for example, the cave we walked up from the well-shaped canyon is very similar to natural formation, because there are no traces of man-made at all.

It started to rain outside, but it didn't seem to be big, rustling, like a lullaby, walking for so long, when the spirit relaxed, everyone felt tired, among the men, Xiaolei and I were the youngest, so we discussed it and decided that the two of us would take turns on duty, and the others could sleep immediately.

In the first half of the night, I was on duty, and in order to avoid falling asleep, I deliberately stood up and stood around the corner with the "Monkey Eagle".

Ten o'clock, eleven o'clock, and soon, in the darkness, I could hear the slight snoring of everyone, and at this time, my eyelids were fighting, and my whole body was even more tired.

In order to relieve my sleepiness, I had to walk back and forth, but I was afraid that it would make a noise and affect everyone's sleep, so I walked a few steps outside the corner, and then walked back and forth, just like that, at a distance of four or five meters, walking back and forth, and in the dark, the "monkey eagle" also walked around me, not leaving me for a moment.

I touched the piece of "monkey eagle" on my body, which was specially asked by Crazy Six to bring it to me, and with this kind of, I could not be smoked by that "ninja incense".

Suddenly, somehow, in the dark, the "monkey eagle" suddenly flew up to my shoulder, and whispered twice in my ear, although I couldn't understand its words, but I could vaguely distinguish it, its voice was very small, but it was very urgent, my heart tightened, and the sleepiness disappeared, and the "monkey eagle" suddenly had this reaction, what was the situation?
