This is actually a very simple trick, and it is indeed passed down from Persian magic. In fact, it uses a kind of gem from the Western Regions. The mirror made of this kind of gem is very dim in the sun, but it is very bright and shimmering in the moonlight, which is called the moon stone.
The reason for this phenomenon is that this kind of gemstone can only reflect the faint cyan light. If the light is too strong, it will be the same as the stone. The stronger the light, the lower the reflectivity.
This mirror in the water is a concentrator of light. When our flashlight hits the mirror, the light is hit vertically to the top of the cave, and then reflected by the small mirrors around the ancient building model to countless such moons on the wall. Stone lens goes up.
The reflected light of a single lens is extremely weak and almost imperceptible, but the gathering of countless lights can reflect the appearance of the upper ancient building on the mirror surface of the ancient mirror in the water. Because it is the superposition of countless faint reflections of three hundred and sixty degrees, no matter where we are, we will not form a shadow on the mirror surface.
Because the moonstone can only reflect cyan light, no matter what color light we use, the image in the ancient mirror is a cyan light source.
"The principle of the shadowless lamp." The fat man said, "I have watched the Science Discovery Channel. Then why, I will see my brother and them in the mirror?" the fat man said.
"There must be some quirks in this ancient building model." I said, "The style of thunder is really powerful. This is Western technology. The development of science and technology in the Qing Dynasty has allowed institutions to achieve this level."
"Why, this crazy, just do this thing to scare people?"
"I can only guess what the purpose of this mirror is here. In several respects, it is likely to be the daylighting device of Zhangjialou." I said, "This is a lighting system, you think. , The ancient building of Zhangjia is deep in the mountains. Assuming that such a huge project is to be carried out in the mountains, this construction site will definitely need a lot of lighting, and this lighting must not be a torch, because such a remote area brings grease in. The huge consumption will be a huge manpower obstacle. These people can know how to plant the wood needed for the project a thousand years later, and it is impossible not to consider the lighting problem."
I did a mental calculation. If there are 200 people working on this place, it will take two to three years to complete the construction, including logging. The lighting in these two to three years cannot be completely dependent on grease.
I looked up at the top: "At first, the sun must be able to shine from above. It is likely that the daylighting mirror set on the top of the mountain is damaged or hidden by them."
As I said, I walked to the edge of the cave. The fat man asked me why. I said: "It is rainy here. Sunlight is the most common, long-lasting, and most unreliable light source. They must have emergency light sources. These fires The ditch should be an emergency light source. When they need lighting, they will ignite the fire ditch here. Here, there must be a channel that can transmit the fire light into the cave where the Zhangjia Ancient Building is located."
After I finished speaking, I waited for the fat man to praise me, saying that I was great, and my heart said that this speculation was simply impeccable. The fat man did not respond, but looked at the surrounding fire dragon wall.
I saw that his expression changed, and I saw the flames on the wall of the fire dragon, which turned out to be dimmed at the same time.
"The kerosene burned out?"
"No, the oxygen was suddenly consumed a lot." The fat man stretched out his hand to feel the surrounding
Air, "What kind of lighting is it for dog days. It's definitely not for lighting here."
I imitated him and felt a stream of air surging.
"The oxygen here has been exhausted, and the oxygen in the cave outside is being pumped in.
Just like cupping, it will create a great pressure difference. All the holes here that communicate with the outside world will suck in air. "
"But what's the use?" I said.
The fat man said: "I don't know, but I have an ominous premonition."
As soon as I finished speaking, I heard a series of chain pulling sounds from the surrounding walls, as if some mechanism had been activated.
"It's over," said the fat man, "Run!"
"What's the matter?" I yelled. He pulled me and ran to the exit, shouting, "The air pressure is on.
Moved the mechanism! The mechanisms here are all stones, which are too heavy and must be driven by air pressure!
This place is an air pump. "
I realized it in an instant, but at this moment, suddenly, the pool under my feet started to move, and after running a few steps, I found that I couldn't stand at all. My feet turned into a slope, and at the same time all the water began to swirl. At the last moment when I could take advantage of my strength, I leaned on the stone beam. As a result, my nails slashed violently on it, and the whole person was lying in the water, and instantly I was caught in the stream.
My heart was awe-inspiring: Damn, there is such an institution under this pool of water? Just when I was worried about how high it was below and what was underneath, I had already fallen to the ground, and the flashlight fell not far from me. Then the water from above kept rushing on me, pressing my whole person into the ground.
I was washed into a panic. Although the pool above was not deep, there were at least a few tons of water. I kept thumping so I could barely find a gap in the current to take a breath.
The half-suffocation state waited until all the water flowed out before stopping. At this time, I was exhausted, vomiting and coughing ceaselessly, and sprayed out all the water in the trachea, and then I was relieved.
Where is this dog day? I wiped my face and looked around, it was pitch black, and the flashlight was charged very far. I touched the ground and found that it was not stones, but sand. The sand was washed out of a big pit, and I was in the middle of the big pit.
It seems to be a bunker.
This fall seemed to be only two or three meters high, and I got up while rejoicing that it didn't seem to be a terrible trap.
I just walked two or three steps in the direction of the flashlight, and I felt something was wrong.
My foot sank into the ground at once, and after three steps, I was dragged into the ground under my feet.
I looked down and found that there was fine sand all underneath. The sand is so fine that it can't bear the weight of people at all, and it is sinking continuously.
I reacted immediately—this is a quicksand trap.
The most common trap in ancient tombs is quicksand. It does not have any sophisticated design. It just pours a large amount of quicksand around the tomb. Because quicksand is the same as water, if you excavate this layer of quicksand, unless all the quicksand is dug out Otherwise, no matter how you dig a hole, it is the same as digging a hole in the water. Every time you dig it, quicksand will come back. At the same time, the craftsmen of the ancient tomb will design flaps on the floor of the ancient tomb. As long as the tomb robbers fall into the flap, they will immediately fall into the quicksand layer at the bottom of the ancient tomb and will soon be capped.
Ghost said that the passage is very safe, how could there be such a trap? I was wondering, while lying on the quicksand, increasing my area to stop the speed of sliding, I touched my body.
I touched it for a long time, and didn't touch anything useful, but my eyes gradually adjusted to the light here. I saw the fat man not far away, he was worse than me, he was inserted head down into the quicksand. Now there are only two feet left, and I want to turn my head out, but the more I toss, the more it sinks.
In this environment, I have learned not to despair. The more treacherous environment in the past, the more I can win in the end.
However, when I was thinking about the problem calmly and quickly, I found that this time was different from before.
There is no time for me to think.
After almost twenty seconds, the sand has not reached my neck. However, almost at the same time, I noticed something was stepped on under my feet.
Is it the bottom of a quicksandwell
It was a hard thing that prevented me from sinking further. The fat man turned it over and yelled. I asked him to come over, and he crawled towards me desperately, only half of the crawl, he didn't reach only one head, and stopped.
I panted hard and felt the sensation under my feet, my heart said what was going on? Are people in ancient times very short? The ancients did not expect that modern people would grow so tall, so they dug the trap too shallow
impossible. Although I believe that quicksand traps can kill people as long as they don't cover a few centimeters, but to be on the safe side, such traps are generally dug very, very deep.
"Innocent, are you okay?" The fat man yelled aside and threw at me.
"It's okay," I said. As soon as he finished speaking, the fat man yelled and stopped.
"What's wrong?"
"There's something in the sand," said the fat man, "the damn thing touched my lungs."
As he spoke, he saw the sand in front of him tumble.
"What is it? It won't be alive, is it."
"No, it's hard, it looks like a stone. I got it out." The fat man said, "Damn it, it feels a little weird."
After speaking, the sand flipped, and a horn-shaped object emerged from the sand. The fat man gritted his teeth, obviously struggling under the sand. Wait a minute, a skull of an unknown animal emerged from the sand.
"This is a deer." The fat man said, "It looks like a poor worm like us." After saying that, he threw his skull away and continued to move towards me.
"Why did the deer come to this place? Could it be that Santa Claus was buried in this building?"
"Maybe I walked in by mistake, there are many more." The fat man continued to thump, and soon took a bone out of the sand. I don't know where it is, it's very long, like a bone spur. "I rely on, it's a lot, it makes me really uncomfortable."
I also flop in the sand like him. It is difficult to move your hands in the sand. Fortunately, the quicksand here is very fine, unlike the sand on the beach, the deeper you dig, the stronger it becomes. Soon I also felt a hard object.
I grabbed the thing and pushed it up little by little, and soon a sandbag bulged on the sand pile in front of me. I pushed it hard and pushed the bone out of the sand. I first saw a ball of hair.
I was stunned for a while, and continued to move up, a hideous face emerged from the sand.
It was a corpse of a person. I saw the faded army green clothes on him, and realized that this should be the victim of a tomb robbery.
"Hello Santa Claus." The fat man finally came to me, "It looks like this is a mass grave. Don't look at it, we have to find a way, otherwise we will become Santa Claus too."
Our method is to use the bones in the sand to connect the torn cloth belts from our bodies to make a bone frame, and then cover anything that can be covered to make something similar to a sled.
We have to make two pieces, first climb on top of one, then climb on top of the other. In this way, the contact area between us and the sandy land can be much larger, so that people will not sink and can move forward on the sandy land.
After I did it, I realized that this way was silly. We cannot go straight, we have to go sideways.
The fat man pointed in a direction and said, "Go over there first. We'll look at the crabs with cold eyes and see how long you run rampant."
"Stupid ×, that's not a good thing." I cursed, and lay on the "sleigh" with the fat man. The fat man handed me the chassis on one side, I flipped over to the other side, and then the two of us rolled over and repeated the same.
All the way forward, it is really rolling forward. Rolling and rolling, suddenly we reached a place where the sand sank down.
I was shocked, and said to my heart, this quicksand can't even hold something with such a large surface area? Then his mother is not quicksand at all, it's just rascal sand. I immediately heard a series of rubbing and crashing sounds from under the sand.
