This is actually a very simple trick, and it does come from Persian magic. In fact, it uses a kind of gemstone from the Western Regions. The mirror made of this gemstone is very dim in the sunlight, but shines very brightly in the moonlight. It is called moon stone.

The reason for this phenomenon is that this kind of gem can only reflect cyan dim light. If the light is too strong, it will be like a stone. The stronger the light, the lower the reflectivity.

This mirror in the water is a light collector. When our flashlight shines on the mirror, the light is vertically hit to the top of the cave, and then reflected by the small lenses around the ancient building model to countless moons like this on the wall. Stone lens goes up.

The reflected light from a single lens is extremely weak and almost undetectable, but when countless light rays are gathered, it can reflect the appearance of the ancient building above on the surface of the ancient mirror in the water. Because it is the superposition of countless weak reflections at 360 degrees, no shadow will be formed on the mirror surface no matter where we are.

Because moonstone can only reflect cyan light, no matter what color of light we use, the image in the ancient mirror will be a cyan light source.

"The principle of the shadowless lamp." The fat man said, "I have watched the Science Discovery Channel. Then why do I see my little brother and the others in the mirror?" the fat man said.

"There must be something fishy in this ancient building model." I said, "The style thunder is really powerful. It is a Western technology. The development of science and technology in the Qing Dynasty has allowed the agency to do this."

"Why is this so crazy? Are you just doing this to scare people?"

"I can only guess now what the purpose of this mirror is here. From several aspects, this is probably the daylighting device of Zhangjialou." I said. "This is a lighting system. If you think about it, the Zhangjia Ancient Building is deep into 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 torches, because Bringing oil into such a remote area will consume a huge amount of oil, which will be a huge human obstacle. These people were able to know how to plant the wood nearby for the project a thousand years ago, so it is impossible not to consider lighting. The problem."

I calculated in my head that if there are two hundred people working on this place, it will take two to three years to complete. Including logging. It is impossible for lighting in the past two to three years to rely entirely on grease.

I looked up and said, "The sunlight must have shone from above in the beginning. It's likely that the lighting mirror set up on the top of the mountain was damaged or hidden by them."

As I said that, I walked towards the edge of the cave. The fat man asked me what I was doing. I said, "It rains a lot here, and sunlight is the most common, longest-lasting, and most unreliable light source. They must have emergency light sources. These fires The ditch should be the emergency light source. When they need lighting, they will light the fire ditch here, here. There must be a passage that can conduct the firelight into the cave where the Zhang family ancient building is located.

"

After I finished speaking, I waited for the fat man to praise me and tell me how great I was, thinking that this assumption was absolutely impeccable. The fat man did not react, but looked at the fire dragon wall around him.

I saw his expression change, and saw the flames on the fire dragon wall dim at the same time.

"The kerosene is burned out?"

"No, it's because a lot of oxygen was suddenly consumed." The fat man stretched out his hand to feel the surroundings.

Air. "***, what kind of lighting? This place is definitely not used for lighting."

I imitate him. Feel a surge of air.

“The oxygen has been sucked out of here, and the oxygen in the cave outside is being pumped in.

Just like cupping, a large pressure difference will be created. All the holes here that are connected to 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 sounds of chains being pulled from the surrounding walls, as if some mechanism had been activated.

"It's over." Fatty said, "Run!"

"What's wrong?" I yelled. He pulled me and ran towards the exit, shouting: "The air pressure is on"

The mechanism was activated! The mechanisms here are all made of stone and are so heavy that they must be driven by air pressure!

This place is an air pump. "

I understood it instantly, but at this moment, suddenly, the pool under my feet started to move. I ran a few steps and found that I couldn't stand at all. The foot turned into a slope, and all the water began to swirl. At the last moment when I could use some strength, I leaned against the stone beam. As a result, my nails scratched hard on it, and I fell into the water. In an instant, I was sucked into the current.

I felt awe in my heart: Damn it, there is such a mechanism under this pool? Just when I was worried about how high it was and what was underneath, I had already fallen to the ground, and the flashlight fell not far from me. Then the water rushing down from above kept rushing on me, pressing my whole body into the ground.

I was washed up in a panic. Although the pool above was not deep, it contained at least several tons of water. I kept fluttering, and I could barely find a gap in the water to take a breath.

The semi-suffocating state did not stop until all the water drained out. I was exhausted by now. I kept vomiting and coughing, and sprayed out all the water in my trachea before I finally recovered.

What the hell is this place? I wiped my face and looked around. It was pitch black, and the flashlight was swept very far away. I touched the ground and found that it was not a stone, but sand. The sand was washed out of a big pit, and I was in the center of this big pit.

It appears to be a sand pit.

This drop seemed to be only two or three meters high. I was glad that it didn't seem to be a fatal trap and climbed up.

As soon as I took two or three steps towards the direction of the flashlight light, I felt something was wrong.

My feet immediately sank into the ground. After taking three steps, I was dragged into the ground beneath my feet.

I looked down and saw that it was all fine sand. The sand is so fine that it cannot bear the weight of a person and is sinking continuously.

I immediately realized it was a quicksand trap.

The most common trap in ancient tombs is quicksand. It has no exquisite design. It just pours a large amount of quicksand around the ancient tomb, because quicksand is the same as water. Therefore, if you excavate this quicksand layer, you will have to dig out all the quicksand. Otherwise, no matter how you dig a hole, it will be the same as digging a hole in water. Every time you dig, the quicksand will rush 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 be quickly submerged.

The ghost said that the passage was very safe. How could there be such a trap? I was wondering while lying on the quicksand. Increase your own area to stop the speed of falling, and touch your body while doing so.

I touched it for a long time, but couldn't find anything useful, but my eyes gradually adapted to the light here. I saw the fat man not far away. He was even worse than me. He was plunged headfirst into the quicksand. Now there are only two feet left, still twisting and turning, trying to turn my head over, but the more I toss, the worse it sinks.

In this environment, I have learned not to despair. The more dangerous the environment was in the past, the more I was able to win in the end.

But just when I was calmly thinking about the problem quickly. I found that this time was different from the past.

There was no time for me to think.

Almost twenty seconds later, the sand was up to my neck. However, almost at the same time, I noticed something stepped on my feet.

Is it the bottom of the quicksand well?

It was a hard object that stopped me from sinking any further. The fat man also turned over and shouted. I asked him to come over, but he crawled towards me with all his strength, only half of the way. He also stopped when he had only one head left.

I gasped. Feeling the feeling under your feet, what is going on? Are all people in ancient times short? The ancients did not expect that modern people would grow so tall. So the trap was dug too shallow?

impossible. Although I believe that traps like quicksand can definitely kill people as long as they can cover a few centimeters, but for the sake of safety, such pits are usually dug very, very deep.

"Tianzhen, are you okay?" The fat man yelled from the side and jumped towards me.

"It's okay." I said. As soon as he finished speaking, the fat man ouched and stopped.

"What's wrong?"

"There's something in the sand," the fat man said. "It's hitting my fucking lungs."

As he spoke, he saw the sand in front of him stir.

"What the hell? It can't be alive."

"No, it's hard, like a stone. I'll get it out." The fat man said, "Damn, it feels a little weird."

After saying that, the sand stirred, and a horn-shaped object emerged from the sand. The fat man gritted his teeth and apparently worked hard under the sand. Wait a moment, and the skull of an unknown animal emerges from the sand.

"This is a deer." The fat man said, "It looks like a poor guy like us." After saying that, he threw the skull away and continued to move towards me.

"Why did the deer come to this place? Is Santa Claus buried in this building?"

"Maybe they walked in by mistake, there are many more." The fat man continued to flapping, and soon pulled out another bone from the sand. I don’t know where it is, but it’s very long, like a bone spur. "Damn, there are so many, it makes me feel really uncomfortable."

I also followed his example and flopped in the sand. It is difficult to move your hands in the sand. Fortunately, the quicksand here is very fine, unlike the sand on the beach, which becomes stronger the deeper you dig. Soon I also touched something hard.

I grabbed the thing and pushed it up little by little. Soon a sandbag bulged up on the pile of sand in front of me. I pushed it hard and pushed the bone out of the sand. The first thing I saw was a clump of hair.

I was stunned for a while, then continued to push up, and a ferocious face emerged from the sand.

It was a human mummy. I saw the faded military green clothes on his body and realized that he must have been a victim of a tomb robbery.

"Hello, Santa Claus." The fat man finally came to my side. "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."

Our method is to use the bones in the sand to connect the cloth straps torn from our bodies to make a bone frame, and then cover it with anything that can be covered to make something similar to a sled.

We have to make two pieces, first climb on top of one piece, then climb on top of the other piece. In this way, the contact area between us and the sand can be much larger, so people will not sink and can move forward on the sand.

After doing it, I realized that this method was stupid. We can't go in a straight line, we have to go sideways.

The fat man pointed in a direction and said: "Go over there first, and we'll try to watch the crab with a cold eye and see how long you can run rampant."

"Silly x, that's not a nice thing to say." I cursed, and lay down on the "sled" with the fat man. The fat man handed me one side of the chassis, and I flipped to the other side, and then the two of us rolled over, and we repeated this.

All the way forward, it is really rolling. Rolling and rolling, suddenly we reached a place and the sand sank down. To be continued
