Chapter 10 Shadow

Nobita obviously noticed this. He clenched his fists and looked at the wall, and his clothes were soaked.

At this time, Liang Qian turned her head strangely and whispered to us with a pale face, "Prepare guns... these things, in the stone..."

In the stone? I think it's incredible. If it's in the stone, how can our light shine a shadow? This is fundamentally contrary to the principle of optics...

But I couldn't think too much about it. Liang Qian winked at Daxiong and said, "Knock!"

Without saying anything, Nobita picked up the sledgehammer in his hand, shouted, and knocked on the stone wall.

Hearing a roar, the stone wall was suddenly knocked out by Nobita, and then the crack spread, and the whole stone wall collapsed.

Liang Qian and Daxiong ran back almost at the same time, picked up the gun in their hands, and were ready to shoot what ran out of the stone wall.

After the dust and smoke, the first thing I saw was several bright spots in the stone wall, which looked like a torch.

At a glance, I thought there was also a team of people in it, but when I took a closer look, I found that it was actually a huge bronze mirror.

Countless ideas in my mind were connected in an instant, and I immediately smiled bitterly and wanted to slap myself twice.

It turns out that the stone wall is artificial. Although it looks no different from other stone walls, it uses a "grey crystal" as a material that can transmit light.

People stand in front with torches, and the shadow is mapped to the mirror through the stone wall, and then the mirror reflects the shadow back to the stone wall, creating a new shadow.

I guess the bronze mirror must not be flat, it must be a convex mirror, because only in that way can the human shadow be scattered into a slender shape.

After seeing this bronze mirror, everyone's tense nerves eased slightly.

People are most afraid of seeing phenomena that are difficult to explain and will feel inexplicable fear of some unknown things, but once these strange phenomena are explained, even if these explanations are just a scam, people will still find some comfort in their hearts.

So everyone present at that time breathed a bad breath and hurriedly set off a torch to check the situation in the wall.

I felt a little sorry to see that those gray crystals were smashed by Nobita's hammer, and now I can't even pick up a few pieces of them.

Such a large piece of pure natural gray crystal is valuable and can be worth thousands of gold in ancient times.

Grey crystal is like the lens of sunglasses. You can't see anything from the outside, but it looks very clearly from the inside out. As early as

It was used to make some organs and secret rooms during the Qin and Han Dynasties.

But I'm not in the mood to study those crystals anymore, because the soldiers around the bronze mirror have made an exclamation.

"Baby..."

I hurriedly squeezed into the crowd to see the huge bronze mirror.

According to my previous judgment, this tomb was built in the Qin Dynasty, then the value of this bronze mirror was even higher. At that time, the bronze mirror was still very rare, and only princes and nobles could afford it. Not to mention such a large bronze mirror, it would take hundreds of craftsmen more than ten years to complete.

I came to the front of the bronze mirror and observed it carefully and found that this bronze mirror is indeed a treasure in the mirror. It is framed with white jade, inlaid with gold in four corners, engraved with four,624 bronze fish lotus patterns, shining and touching. Even in my humble opinion, this very well-preserved bronze mirror can be regarded as a rare treasure.

I stood up straight in front of the mirror and found that the mirror was not completely flat, but slightly raised in the middle, which was indeed a convex mirror.

The figures of me and the soldiers were pulled long in the mirror, which looked a little funny.

Lao Huang said that when he goes back, he must bring more team members back and bring this bronze mirror back to the state for research, but now it is more important to find someone, so he asked the soldiers not to look at the bronze mirror and find out if there is any way.

Strangely, everyone looked around and found that this stone room was a dead end, as if the ruins had come to an end here.

And everyone knows that this is absolutely impossible, because if this is the end, where did the investigation team go? Has the world evaporated?

Finally, we put all the suspects on the bronze mirror, because the mirror is so big that there may be a secret behind it.

All 13 of us came to the mirror to look at it. The six torches together emitted a very dazzling light, reflecting our shadows on the surrounding walls, shadowy, like ghosts.

I don't know if a series of strange things have experienced have made all the people present like ashes. Coupled with the depressing atmosphere under the ground, the air is full of strange haze.

Now I just want to save people and leave this damn place immediately. I think the current atmosphere makes it difficult for me to breathe...

At this time, the picture on the mirror suddenly changed, which surprised me.

The people next to me were so shocked that they couldn't speak and stared at the mirror.

I can't say clearly about this change in the mirror. I know that it is a kind of wax that uses the temperature of the torch to melt the wax on the mirror, and then with the change of wax, the reflection angle of the mirror slowly changes.

At first, the mirror was still a convex mirror. As the wax melted, the mirror began to sag in and finally completely concave.

Then use the light-gathering effect of the concave mirror to cast the light of the torch somewhere at the top of the cave at a 45-degree angle.

Looking up along the light, I felt my scalp a little numb.

Because the place illuminated by the light is a huge stalactite, the stone is like a damp paper with a light yellow color, and the stone is covered with a milky white insect without eyes.

This insect is obviously very afraid of the light, squeaks, and immediately escapes.

I know this insect. Its name is wetland sting bee, which is the most poisonous kind of bees. Because it has lived in caves for a long time and its eyes have deteriorated, it is afraid of strong light and is irritable. If it is stung by them, half of its body will swell up. If you don't see a doctor in time, it will die of shock.

I saw the swarm of bees crawling away, revealing the upper half of the skull of the stalactite, which was inlaid on the stone with a black candlestick in its mouth.

I know that it must be a mechanism to open a secret hole. I said that this ancient man was really scheming. If ordinary people certainly didn't expect that the mechanism would be in a pile of bugs, because these bugs are very common in wet caves and very difficult to mess with, ordinary people would not touch it. We.

And we also happened to use torches to bake the mirror. If we use a flashlight, we will definitely not find the mechanism.

However, I have another question in my mind, because after the mausoleum is built, it will not be ready to open again after the tomb owner is buried. Generally, the more you close the tomb, the better, unless they welcome tomb robbers to borrow money...

So why did the owner of the tomb here design such a mechanism to allow people to enter the main tomb? I can't find the answer for a moment...

While I was thinking, Lao Huang had picked up a burning torch stick and stabbed the candlestick in the mouth of the human skull.

The candlestick made a click, slowly shrinking into the mouth of the human skull, and then the mouth of the skull closed seamlessly.

Then I heard a rumbling sound on the side of the cave. The two stone walls retreated to one side, and a huge blue-gray stone gate came out of the road.

Everyone looked at each other and swallowed a mouthful of saliva.

I also took a deep breath and began to guess what kind of secret is hidden behind this secret door?

A huge stone door appeared in front of us.

The door is more than ten meters high and is made of cyan rocks. It is covered with moss and other plants, and you can only faintly see what patterns seem to be carved on it.

A dozen of us came to the bottom of the door and looked at its structure.

I can't determine the material of this door. I can only say that it looks like basalt.

Basalt is a kind of rock formed during volcanic eruptions. Due to different degrees of oxidation, basalt also has completely different structures. Some are as soft as wood, while others are as hard as steel.

The basalt used in this door is obviously the latter. It is very thick, and the left and right doors are very complete, and have not decayed for thousands of years. I put my hand on it and immediately felt a kind of weight from ancient times. It was as cold as jade, with a sense of vicissitudes of time.
