Thirty minutes later, we moved the wooden boat to the bank of the Sand River, searched the location of the wooden boat for a while, and immediately found that this was just a temporary foothold, very simple, without any valuable clues, one of the easier things to find is that the boat and the frame here are not the same kind of wood, in fact, to be precise, the boat and the frame are not the same year as the wood was cut.

It is impossible to calculate the year of manufacture of this wood, but the good thing is that the hull does not have any wear and tear, whether it is driving in the sand river or on the water, it is almost the same, but according to the environment here, it is speculated that the wear surface will be faster when driving in the sand. And the boats here are basically not used.

The wooden shelf is different, the color of the surface is already a little dark, this cave is full of sand, and the moisture does not exist for long at all, so the oxidation degree of the surface of the wooden shelf is at least a thousand years.

The surface of the poplar wooden boat is not very smooth, the manufacturing is very rough, the one we are moving here is not big, four people can just fit it, the hull is fixed with metal strips, and the gaps have not been treated with tight Mouton oil, so at a glance you know that this ship cannot be driven on the water.

The speed of the sand river was very fast, and almost before we could get on the boat, the boat had already been taken out for a long time, and several of us hurried and hurried, and finally jumped on the boat in the moment when the river bank narrowed.

"Damn, this broken boat can't even fit my buttocks, so I'll just say take another one." The fat man moved his ass and pressed himself against the stern, and he alone could already stabilize the stern of the whole boat.

When I jumped on the wooden boat, I choked on the sand and coughed a few times before saying, "Don't you see the hole in the big ship?" If you go up to that river, you will sink. ”

The fat man sighed: "The river is sand, not water, as long as it can withstand the pressure, it can't sink." ”

As soon as the fat man finished speaking, a handful of things suddenly rushed out of the board of the boat in the direction where he was sitting, and the fat man wondered how to look at it, and wiped it with a handful, and immediately I saw that it was sand, and the fat man wiped off the sand on the surface, and soon a handful came out.

The fat man was even more surprised, and he looked at the three of us, and went straight to wipe the plank clean, and we found that there was a hole about the size of a cigarette butt.

Seeing this, I spread my hands, and the fat man also said "hey", and saw that he was a little embarrassed to break off a piece of wood on the side board and plug it directly, and then the sand powder no longer leaked.

"Haha! Accident, accident. The fat man snorted, but no one paid any attention to him.

The power of the flashlight was running out, and the light source was obviously depleted, so we simply turned off the flashlight and used the torch that had just been converted from a broken ship.

The road ahead is long, I don't know how deep it is, and the first hour or two is still a little fresh, but after driving for a long time in the smooth underground Shahe Ancient Road, there is really nothing to see anymore.

In order to maintain our balance, the four of us were on one section of the boat, and although the boat was shaky, there was no sign of capsizing, and in this way, we kept flowing down the sand towards our unknown goal.

I heard the sound of laughter, after the torch was extinguished, no one continued to light it, and I don't know how long it was, I seemed to have had a long dream, no antecedents, no consequences, nothing, just the back of a person standing in the thick fog.

After thinking about it for a long time, it dawned on me that I had seen that back, at noon before everything happened, on the day when the fat man and the fake Jiang Huai came to me.

The fog was not thorough, I had no impression in my dreams, and it had been so long that I was still vague about it. Some people say that dreams are mirror reflections of the subconscious, and many things that exist in the subconscious will be kneaded and combined into a new thing by the dream.

The dream ended unconsciously, after opening the eyes, it was still pitch black around, we didn't hit the riverbank, which was very lucky, unattended, in the dark underground river channel, although it was a sand river, but the process was still shocking when there was light.

There was the sound of sand rubbing around, but now there was another one, and that was the snoring of the fat man, this guy also slept comfortably, and I already felt numb on my back when I leaned against the plank for a while.

I was about to get up, but as soon as I moved, the hull of the ship shook a few times, and in an instant someone grabbed my wrist, and according to the strength, it seemed to be the old generation, and at the same time, I heard his voice.

"Don't move, the sand flow here is too fast, and if you move a little more, the boat may capsize." The old generation whispered in the dark.

I thought, and slowly went back to my previous movements. In a flash, Manan, who was at the bow of the ship with his back to the direction, hit the lighter in his hand, and saw that he used a flat iron can to squeeze something on the head of the wooden stick at his feet, and the flame of the lighter burned at the touch of the torch.

I rubbed my eyes and stretched very carefully: "Where are you?" I asked.

The two men in front of them did not reply immediately, and after the fire was lit, they went to observe the wall of the cave where we were, which was smoother than the previous one, but what appeared on the top of the cave attracted our attention even more.

"That's ...... What's that? I exclaimed, and my body rose involuntarily. Because the moment I saw the roof of the cave after the fire was lit, I was so frightened that I almost fled.

The side of the cave wall is in a glazed state, polished by sand powder for thousands of years, here is like a glass surface, but above our heads, the texture of this glass surface has changed to a mirror surface, as for why there is such a metaphor, it is because we look up and see us hanging above the cave wall in reverse.

It took a few seconds for a few of us to realize that it was actually just a specular reflection. At the first moment, we were really frightened, and when we looked up, we were not looking up at the cave wall, but looking at us.

The fat man tilted his head to look at the sky, I shook him awake, he hurriedly got up, and thought something was wrong, I pointed to the top of his head, he looked at it for a few seconds, and then grinned: "What's the fuss, isn't this the high-temperature glass reaction." ”

"How can there be heat here?" I was amazed.

"Oops." The fat man was helpless and looked at Manan: "Didn't he say everything in that, the sand flow sprayed out from the ground, what else can there be besides the eruption over the mountain." As he said this, he suddenly gasped and grabbed a handful of sand in the sand stream: "If it is really a volcanic eruption, then this sand powder can be explained." ”

Several of us looked at him, but the task of asking the question fell on my head, and with a light sigh, I asked, "What explanation, you should tell me?" ”

Fat sighed again: "High temperature, do you know what the raw materials for making those high-tech silicon crystals are?" ”

I just thought about it and nodded, "Sand?" ”

The fat man clapped his hands: "Isn't this right?" The sand must first be treated at high temperature to extract the crude raw materials, and the silicon crystals are so delicate. The fat man glanced at the sand powder in his hand: "It's just that this seems to be a little thick, and it is estimated that the purity is not enough." ”

I gasped, not because of the sand, I didn't think much about it, so I asked directly, "You big old man, how do you know this." ”

The fat man saw my suspicious face, he originally wanted to pretend to be a little bit of a joke, but when he saw that my face was even more strange, he said: "Isn't this the 21st century, if you don't know a little about high-end industries, you should be outdated in this business." ”

I grinned, ignored it, and continued to look at the top of my head, and the scene above was the reflection in the mirror, which was, no, a whole naturally formed silicon crystal mirror, which was really natural.

In the mirror above my head, I saw the fat man twisting his head again and closing his eyes to sleep, and the other two people didn't make much movement, each looking at the board and thinking about something, and the old man clutched in his hand the package wrapped in a gloomy wooden box wrapped in clothes.

This angle looks a little novel, but after a minute or two, there is nothing new, and when I was about to turn my head and rub my neck, I suddenly saw some discordant pictures.

The light source is dim, but because of the mirror reflection on the top, this large area has become a little brighter, but it is shimmering, and it is more difficult to see some details.

Where the sense of disobedience appears, it is not difficult to find that the fat man's backward head in the mirror trembles, and I don't know if he is comfortable like this, but his head and neck are generally thick, and there is really nothing to worry about, at most it is a stiff neck.

And this difference is the position of the fat man's cheek ears, my cheeks are very clear in the mirror, and there is nothing unclear, but the fat man's cheeks really look a little weird.

It was then that for a split second, I saw what it was, sand, a stream of sand. I was startled, and immediately jumped up, and instantly shook the fat man, who was a little annoyed, and seemed to have just had the intention of falling asleep.

When the fat man saw my babbling appearance, he immediately scolded: "I said that you kid has some nerves for some reason." ”

"You...... You...... You ......, "I've been you for a long time, and you haven't spoken."

"Hysteria, you." The fat man scolded impatiently again.

I turned my head to look at Lao Dai and Manan, but their eyes only looked at me a little weird, Manan even looked at me a little bit of a neurosis, I was speechless for a while, pointed directly at the fat man's neck, and held back a sentence for a long time: "You...... Something around your neck. ”

"Neck?" The fat man glanced at me, but when he saw that I was so puzzled, he touched it with his hand, but when I saw the appearance of his neck at this time, it was no longer the same as before, the fat man didn't touch anything, and I also saw that his eyes were weird, and I only heard him scold softly: "Neurotic." Then he lay back in his original position.
