When Lao Tang said these words, he said lightly, but Wang Sichuan and I still felt a sense of indescribable creepy.

Twenty years ago, a Japanese "deep mountain" bomber took off on a underground river 1,200 meters underground, flew over an underground dam, glided into the huge underground cavity outside the dam, and disappeared into the boundless darkness. None of us knows what this "deep mountain" will encounter in the darkness and what pilots on the plane will see.

Such things alone have exceeded my acceptance. Now we even find that in that darkness, a mysterious telegram has actually been transmitted. This is really incredible.

Then I thought of the large amount of accumulated airborne and bundled goods and supplies here, and I immediately understood where these things were to be transported.

All the arrangements of the entire base here are obviously done to air-drift people into this huge underground cavity. And if Japan had not been defeated, such air-drift activities would be carried out countless times until all the supplies in this warehouse were air-dropped.

Lao Tang said that this discovery was really shocking, so they needed to verify that they came down to the dam to find this antenna. If it were true, this matter was completely of another nature. I asked them if they had found that antenna? Lao Tang shook his head and said that there was not yet, because they could not go down to the bottom of the dam, so they came here to find a way to continue.

If you go on, what is this concept, it goes without saying.

Twenty years ago, Japanese people would definitely think of similar questions. When they first saw this nothingness, they would definitely ask themselves: What is this place, what is inside, and how to go on?

Now the situation we are facing, obviously, says that they should have solved the last question and sent back the message.

At this moment, I had a very clear idea of ​​what was happening here. Twenty years ago, the Japanese discovered and carried out a lot of infrastructure transformation here, and successfully used strategic bombers to airdrop. Although the bomber crashed during the final landing, the whole process can be described as crazy.

I can even infer a lot of details. For example, this crashed "deep mountain" will definitely not be the first aircraft to fly into the abyss. In order to test the feasibility, the wreckage of small fighter jets we discovered underwater before must be the first choice for flight feasibility tests. Japan has quite mature aircraft carrier technology, and flying a fighter here is much simpler than a giant bomber.

When I asked Lao Tang about his next plan, he told him about his plan.

Unlike Lao Tang and others, engineers must be rigorous, so they must verify something so that their reports are 100% correct. This is the work principle issued by Chairman Mao that year. Engineers are always in front of the army, paving roads, and building bridges when they encounter rivers. Any mistakes may lead to the exposure of strategic intentions, so they must be rigorous.

So Lao Tang told us that they must be completely sure that this signal was sent from the abyss, and that this conclusion can only be drawn if the matter is true, otherwise it will cause great misleading to the organization.

The search and rescue work must also continue. We do not know the situation outside the dam, and too specific plans are useless, so we should still respond to changes. The search for the dam will be completed by the engineers. Our exploration team should not be separated. The exploration team's work has been completed.

I thought to myself that the mission of the geological exploration team had already ended. Under this nothingness, it would definitely not be an oil lake of hundreds of thousands of hectares. The activities of the Japanese here obviously have little to do with the exploration of geological resources. From the beginning of entering this underground river, our mission was actually over.

This is understandable. We are indeed unable to interfere in the next thing, we have no way to move forward, nor have we retreat.

So no one objected, and Lao Mao did not express his opinion. He drank tea silently and listened to us. Looking at his expression, he seemed to feel that what we were talking about was ridiculous.

I didn't care at the time, and I didn't expect that I would feel this way soon after.

With a nightmare shock, I fell asleep. Under such stimulation, I inevitably had a long dream. The huge nothingness in the dream was like a huge mouth, and I stood at the top of the dam and saw it spread towards me in the strong wind. The surrounding rock walls were slowly corroded by the seemingly endless darkness. I dreamed that I was sitting on the plane, flying without a destination in nothingness, nothing around, and no matter how I could fly, I couldn't fly.

This kind of panic is even more terrifying than the first one, but I didn't wake up because of this. I slept for ten hours. It was not until I was eaten that I was awakened by Wang Sichuan.

Lao Tang and the others have already taken the people out, and Lao Mao has also left. I have expected that even if we don’t move, Lao Mao will definitely follow the engineers, because he must have other identities, otherwise it would be impossible for Rong Aiguo to send a assault boat to come in to save us.

Intuition tells me that everything here is beyond my understanding and I no longer want to think about any part of it.

While I was having a meal, I listened to Pei Qing and Wang Sichuan about the dam. They were guessing what was going on here in the ice cellar.

We only have a vague understanding of the structure of the entire dam, especially this kind of dam for special purposes. We have no idea what some facilities are used for here, and naturally we cannot speculate on possible structures.

The only thing that is clear now is that there are caissons sinking underwater on both sides of the dam to transport supplies. Under the water level of the dam is a huge ice cellar with a large number of shells and a hoisting warehouse that stocks up a large amount of materials.

Wang Sichuan ate vegetable puree and said to us: "I feel that the place we are should be the bottom of the dam. Because if these large-diameter warheads are used to blow up the dam at the end, then they should be placed at the bottom of the dam so that the part above the dam can be effectively destroyed when exploded."

However, it is hard to understand why all of these warheads are frozen? Only nitroglycerin needs to be frozen, but nitroglycerin cannot be used as shells. High temperatures will definitely cause the warhead to explode faster than shell shells when it is out of the cavity, and the transportation risk is too great.

Speaking of which, there seems to be only one kind of thing to preserve at low temperature, that is, bacterial warheads.

There are quite a lot of historical records about the Japanese devils' biological warfare in China, but most of the people only know 731.

Only a small number, for example, those of us who often drill woods and holes for geological exploration, can know that 731 is just the tip of the iceberg. During decades of geological exploration, we have discovered a large number of cement buildings left over from the Japanese invasion of China in the depths of the jungle in the northeast. These buildings have basically been completely burned, but from the perspective of the building structure, there are traces of dungeons and anatomical rooms. A comrade of my army once told me that the scale of bacterial warfare is definitely more than that in China.

It is unlikely that there are bacterial bombs outside, which has no intersection with the environment here. The Japanese explore this area with a clear purpose and will not inexplicably pile up a bunch of bacterial weapons here. What are these warheads used for?

I had a thought at that time: What if these compressors stop working? Although the temperature here is very low, these ice cubes will gradually melt. So, what changes will happen to the warhead?

Obviously no one can guess it.

Lao Tang took people out, and the ice cellar outside should not be very big. I could hear some big noises, and people came back from time to time. These recruits were so cold that they were snot flowing. At this time, they really looked like they were still children.

Waiting so boring, we chatted for a while, but Wang Sichuan couldn't sit still and shouted that we would go out to have a look.

We wrapped our coats tightly, walked to the ice cellar outside, and walked in the direction of the sound. After walking for more than a dozen steps, I felt something was wrong. It seemed that it was even colder here, and my eyebrows were all frosted, and it was not so cold before.

We rubbed our hands and stomped our feet, like the white-haired wind in the winter of Daxinganling. Soon we saw a figure in front of us. When we walked over, we saw Lao Tang stomping his feet while shouting. The sound became louder and louder, as if he was smashing something.

This is the middle part of the ice cellar. When we approached, we immediately discovered what they were doing. They were smashing a pit on the ice.

Several soldiers were holding simple tools and trying hard to smash the ice, but it seemed that the effect was not great. There were no deep depressions on the ground, only large pieces of crushed ice.

I felt a little dangerous, there was a bomb below, and I didn't know what Lao Tang was doing, so I walked to him, asked him to be careful, and asked him what he was doing?

His mouth was so cold that he was purple. He shivered and asked me to see under the ice surface, which was a large shadow. Because the ice surface had been smashed into a pothole, it was difficult to see clearly what it was, but it was certain that it was not a warhead. This warhead was very large.

After walking around the shadow, I recognized it and couldn't help but take a breath of cold air - the shape of the shadow looked like a huge paper clip. But it was not solid, and there were many U-shaped protrusions around the paper clip.

I recognize this shape, it is a large transmitter antenna.

Although I knew this thing must exist, I was also confused at that time. I wondered why this thing was frozen in the ice?

After a closer look, there is not only these. In addition to the black shadow of the antenna, there is another huge and lighter shadow, which should be something buried deeper in the ice layer. This shadow is three times the size of the antenna. Judging from the shape, it is a huge colander-like disk.

"What the hell is this?" I asked Lao Tang with a trembling trembling, "Is it the antenna you are looking for? How come it is in the ice?"

"This is not an antenna." Old Tang pointed to the U-shaped protrusions on several corners, "This thing has a nickname called 'Wildsburg Giant'."

"What?" I was cold and surprised, and was stunned for a moment, "What giant?"

Lao Tang said it was a bit difficult to explain these to me. He was very familiar with these things, but to explain them clearly to me, we have to talk about technology. Anyway, to put it simply, "Wildsburg Giant" is a nickname, a tracking radar imported by the Japanese from Germany. It is mainly used to automatically control searchlights during night air defense. The Japanese do not need such advanced night tracking technology in China, so there are not many of these radars, and most of them are arranged in Mongolia and Pacific battlefields. China initially tried to imitate this radar, but it was unsuccessful, and later this technology was eliminated.

At that time, this kind of radar should be the most advanced tracking device.

This is the knowledge they popularized when they set up radar stations. Later, the radar soldiers became independent from the Engineering Corps and became a special radar unit.

Old Tang said that they found this huge shadow when searching for this ice cellar. He was surprised, but the shadow should not be as big as we look now. The illusion of this size is caused by the different ice density around the plate and the outer ring.

They believed that this radar should be the backup navigation radar at that time. Indeed, such a difficult flight mission required precise navigation.

After hearing this, Wang Sichuan asked, what do you want to dig it out? Is this related to the telegram?

It wasn't just because of this. Old Tang Dao said that, he took out a piece of paper from his pocket and drew several figures with a pencil. He said that they divided several groups to search here, one group led by Lao Mao and searched around the hoisting warehouse. There was such a huge "deep mountain" there, and there must be a huge lifting device leading up to it. His group searched for this ice cellar, looking for the brake devices of the caissons I mentioned, and at the same time gave a preliminary understanding of the situation of the ice cellar.

Several figures are the floor plan of the ice cellar they drew. The engineers have the ability to draw, and even a few of them show their expertise. The compressors and circuit diagrams around them are marked, but what I care more about is that they draw the distribution of shadows under the ice.

Old Tang pointed to several places with a pencil and said, "The shells you mentioned are distributed around the ice cellar, forming a ring, and there are a lot of them. In the center, the 'Wildsburg Giant' we found. Look at the very light patterns here, these shadows with arms thickness as thin as ladders are sliding rails of the "Wildsburg Giant"; at the same time, we found four black spots as big as the head of the Liberation Truck, which should be two sets of searchlights that match the 'Wildsburg Giant'."

I nodded and he continued, "Don't you think it's very strange? Put a radar navigation system in the middle of a pile of bombs. What does this mean?" I was completely frozen and couldn't think. Wang Sichuan sneezes and said, "Is this a condom?"

After Wang Sichuan said this, I immediately understood what he wanted to say. But if this is the case, this matter would be even more incredible.

The so-called trap can be understood without explanation. It is a trap that puts attracting objects. Wang Sichuan said that this situation is similar to the engineer burying landmines. To make a fake target, mines are buried around and the enemy is brought closer.

All the shells here have been removed from the core cap and are in an excited state, which is indeed a bit like it; but what is the use of the radar in the middle? Is this the "bait"? I can't imagine what radar can attract. This is the navigation radar. Do they want to lead their planes to the dam and destroy this water conservancy project?

This is no longer logical. Why did the Japanese do this?

It was too cold and we couldn't hold on anymore. Lao Tang asked us to go back. I really wanted to help me, so I could help Lao Mao.

We returned to the resting place, took a few sips of hot water and didn't want to go anywhere, and I felt an uneasy atmosphere more and more.

I suddenly began to wonder why the Japanese abandoned this place. Is it really as simple as we thought?

There was no sign of military destruction in the entire underground system. Obviously, they retreated very orderly, with a large amount of materials piled up here, that is, there was no blasting, and there was no sign of burning the documents.

We saw a driver's body in the "deep mountains". The "deep mountains" were seriously damaged, but what about other crew members? Why was that body left in the cabin?

I don’t know if the cold outside penetrated into the warehouse or if my thoughts made me uncomfortable, but I continued to fight and couldn’t stop it.

I still remember the feeling fresh in my mind. It was not fear, but the shock that countless discoveries brought me before and the trembling that emerged together.

What flashed through my mind was, was this base already abandoned when the "deep mountains" returned to the voyage?

When I thought of this, the expression on my face must be very strange, which made Wang Sichuan and Pei Qing look up at me. Wang Sichuan thought I was uncomfortable and asked me if it was more appropriate to sleep. The body is the capital of revolution, so don’t force myself.

I shook my head and asked them, "You said, how long did that 'deep mountain' fly in that abyss before I came back?"

Wang Sichuan asked me what it means? I asked if there was a possibility that this "deep mountain" would crash by relying on the pilot's ability to make a crash. Therefore, the pilot's body was left in the wreckage of the plane, and the surviving crew members left by themselves and disappeared.

When I said that, I didn’t understand the cruise capability of the “Deep Mountain”. Afterwards, I checked: “Deep Mountain” can fly at full speed and can cruise for ten to fourteen hours.

Such a huge underground fortress, it takes at least hundreds of hours to completely evacuate. When they return to the "deep mountains", they cannot completely evacuate no matter how fast they are. So my idea should be unlikely.

But no one expected these details. Wang Sichuan said it made sense. Pei Qing said to me: "It doesn't look like there is an emergency here. They haven't even removed the transmitter and the password book is there. This is more calm than a forced landing."

It felt like it was not the evacuation, but the entire fortress, who suddenly disappeared.

Old Tang also mentioned this concept. When they came here, they found many documents covered with canvas. Obviously, the Japanese did not think about not coming back from now on, as if they were just making a temporary handover preparation. But obviously, they did not come back after they left.

Something must have happened here that we cannot imagine. The underground fortress was definitely in a state that we could not speculate on in the last ten hours. All this should have begun to happen after the "deep mountains" flew into the abyss.

The more I thought about it, the less I understood it. I stood up and looked at the sand table, trying to find some clues from it. At this time, Wang Sichuan suddenly nodded, raised his head, and looked around. I was also infected by him, but found that he was not watching, but listening. In a very far place above our heads, an air defense alarm sounded again. In the room, the alarm sounded very dull and light. It was easy to mix with the sound of the exhaust fan if you didn't listen carefully.

Pei Qing looked at the watch and the alarm rang for a long time, then stopped abruptly.

He breathed a sigh of relief and said, "Three minutes long, this is the frequency of alarm releasing."

I felt relieved and said to Amitabha Buddha. It seemed that the situation above had improved. Before I could finish thinking about it, there was another huge movement of the machine running deep in the surrounding walls, rising and falling.

We were surprised by what happened. Several soldiers walked out of the depths of the warehouse excitedly and told us good news. The flood discharge of the dam was over, and the heavy water from the upstream rain had all leaked into the abyss. I believe that the thick fog will soon retreat under the warning line. We can find a way to go back.

Wang Sichuan was about to ask them how they knew, but something happened on the other side. Several soldiers from Lao Tang from Bingjiao came in with something in front of Bingjiao and shouted to us for help.

The thing was so sank that the four of them were carrying it, and they could only drag it on the ground. We immediately went up and saw that it was a lump of ice, as big as a coffin. Wang Sichuan shouted, and then he came up and gritted his teeth to lift it up before lifting it off the ground. Pei Qing and I went up, and the soldiers there shouted, "No, no, we have enough, there is still something behind us!"

Immediately, someone carried a piece of ice from the ice cellar and came out. I called others to go up and gritted my teeth to hold it up. It felt quite heavy. Then I saw a ball of stuff frozen in the ice.

I lifted it inside and put it down, and felt that my feet were being pressed a little shorter. I asked them what they had dug out. The soldiers flipped the ice and let me see it. I saw that the ice was so cold that it turned out to be a dead person.
Chapter completed!
