As they walked along the second cave, there were traces of humanity everywhere as far as the eye could see, and it was clear that the second cave was clearly a human work - at least it had been artificially modified.

The group walked for more than ten minutes, and suddenly it became clear that it was an extremely wide underground cave.

At that time, the middle-aged officer's team was tasked with protecting the safety of those expedition members, and he was not yet twenty years old at the time, and because of his personality, he directly ignored matters that had nothing to do with his own work.

Now recalling the experience more than 30 years ago, he vaguely remembers how excited the expedition members were at that time, and vaguely remembers that someone shouted that this was the mine cave, and the ore contained here is very rare and valuable.

In the next month or so, his life was very monotonous and boring, every day was inside and outside the hole, up and down the hole, doing the work of porters and security guards, there was no technical content at all, and there were more than a dozen strange faces in the cave, the middle-aged officers of the year overheard it, and most of the people who came were geological experts.

They were excited about the stones in the cave, as if they were not stoned, but gold.

Later, something happened in the villages near the cave, and he heard about it, including the villagers who had the courage to go down to the cave and try to steal things.

Speaking of those villagers, he is still confused.

At that time, their group was on duty, so they took guns to drive away a few villagers, and the villagers ran towards the depths of the cave in a panic.

He only knew that there was an underground river in the cave, and there were several underground lakes, and the water was still very deep, because there was an order from above to let them go near the inside of the cave - in that era, "military orders were like mountains", and they could not violate them in any case, so they did not chase after them.

In fact, what can you do if you catch up, it's nothing more than to drive them back and scare them, after all, they are villagers, and they can't ask for people's lives!

For most of the day after that, they deliberately "opened the door" in order to let these Diao people leave.

After all, this is a small matter of sesame seeds, and then it was left behind, thinking that the villagers had already returned to the village, and then the things were the same as I learned, and several groups of villagers returned to the village, all of them looked exactly the same, all of them were delirious, mentally disordered, and unable to communicate with people normally.

Later, these people were taken to a sanatorium in Qinghai Province, where they were given a full body examination, and some plant residues were found in their stomachs that had not been completely digested.

Of course, these things were not clear to the middle-aged officer who was only eighteen years old at the time, and it took the effort of the ninety-sixty-two tigers to ask about them after the accident.

He also asked that among the three groups of people who appeared one after another, three of the same people were the same in addition to their height and appearance, and even the fingerprints on their hands were exactly the same.

In medicine, or in medicine to be precise, this kind of thing is absolutely impossible, because even twin brothers cannot have exactly the same fingerprints.

In criminal investigation cases, fingerprints are used as "identity cards" to determine a person's identity, and according to the existing theory of criminal investigation, these three people should be the same person.

But in fact, there were three of them.

Continue your research.

Another strange thing was discovered, which proved that the three people were not alone.

At that time, one of the villagers had a scar on the left side of his chest, which seemed to have been scratched by climbing a tree when he was a child, and the researchers inadvertently found that only one person's scar was on the left side, and the other two were on the right side.

What's going on? It's puzzling. March Chinese

Later, a detailed study of the contents of the stomachs of several people revealed that there was a special mineral element in the stomach food, which was different from all the elements known on the earth.

But there was no other food in the food residue of the fungus - that is, the strange substance was in the food they ate in the cave, but not the fungus food - but the problem was that there was no other food in the stomachs of several people.

Could it be the water they drink......

The researchers reported the situation to their superiors, who in turn reported back to the people involved in the study of the cave, so they sampled several waterholes deep in the cave.

The mineral was found in the water of one of the pools, about the size of a basketball court.

What happened after that was not clear to him.

During this time he was sent to do something else, but before he could return, he heard that something had happened in the cave, and everyone had died in the cave, including his comrades, including geologists, and miners.

According to the information he obtained, he was the only person who had ever survived the mine.

Of course, the middle-aged officer may not know that there is a Sun Jingshui - in fact, I don't understand what kind of existence this Sun Jingshui is.

Speaking of this, the middle-aged cadre took a deep breath, took out a cigarette from his pocket, put it in his mouth, took it down again, and then smiled dumbly at a few of us: "This is what happened back then!" Actually, I didn't figure it out! My brothers...... All of a sudden, the big brothers died, and they were all killed...... I just can't take it. ”

During the whole process, I saw his hands shaking constantly.

Everyone has a knot, some knots will slowly untie, and some will become stronger and stronger, and finally become a dead knot.

Director Qin patted him on the shoulder: "Chengliang! I don't know how to persuade you - since you took the initiative to ask for help this time, then let's find out what happened back then, I think this can be regarded as an explanation to all big brothers! ”

Later, I learned that this middle-aged officer's name was Zhang Chengliang, and he was the captain of a special unit of the Jinan Military Region.

At this time, looking at Zhang Chengliang again, he was already in tears.

"I was also a little emotional for a while, and I was really embarrassed...... Everyone should have rested enough, let's go! ”

"Good! Let's go. ”

A group of people raised their legs into the hole, I don't know if it is a psychological effect, after entering the hole, I felt a cool breeze rushing in my face, so I couldn't help but shiver.

The cave was very dry, and in a trance I thought I was still in a cave that led to the cracks in the ground under the Yellow River that day - this was not a feeling, let alone an illusion, and the cave I was in at this time was exactly the same as the cave of that day.

The cave appears to be flat, but in fact the entire ground can be felt to be slightly sloping downward.

Sure enough, after walking for more than ten or twenty minutes, my eyes suddenly opened up, and with my extraordinary eyesight, I couldn't see the end.

The cave outside is more than 100 meters straight up and down, and according to the inclination of the second cave, plus all our time, it is estimated that it has gone down more than 200 meters, which adds up to more than 300 meters below the ground.
