Just do it.

Ye Cheng tied a safety rope to his body and began to climb up.

This cave is full of barbed stalactites, and it is quite difficult to climb up.

Even if Ye Cheng's physical strength is amazing, it is very difficult. Every time he climbs for a period of time, the safety rope will be fixed.

No matter how good the kung fu is, the taste of falling from a height of tens of meters is absolutely unbearable.

After climbing a distance, Ye Cheng found out.

In the middle of those stalactites, there is a groove that spirals upwards.

There is a thick layer of black matter in the groove, which looks sticky and has penetrated into the gaps in the stone.

Ye Cheng smelled it, and the smell was a little weird, but he recognized what it was.

"Little brother, what did you find?" Fatty Wang asked loudly when Ye Cheng stopped.

Others are also waiting curiously.

One after another light shines upwards, shining brightly around Ye Cheng.

Ye Cheng said: "There is kerosene on it, and, looking at the traces, it should be circling upwards, it is very likely that it was used for lighting during the construction!"

In ancient times, there were only two methods of construction in this dark cave.

One is to open a hole to bring in the light from the outside, and the second is to use a lot of kerosene to burn and illuminate the surroundings.

The first method is not common, the second is very common.

In some large imperial mausoleums, a fire pit is even built around the imperial mausoleum. After lighting it, the entire tomb can be illuminated, making it convenient for workers to work day and night.

"Hey, don't look for kerosene, hurry up and look for something related to this mirror!" Fatty Wang shouted!

Others didn't think much of it.

I just thought that the kerosene was used for lighting.

After all, in such a dark cave, it is normal to use kerosene for lighting.

Only Li Duoduo frowned and muttered: "Strange, if it's just for lighting, why build a spiral fire path? Isn't it easier and more convenient to dig a few grooves around?"

But he didn't say anything.

Ye Cheng continued to move up.

When he climbed nearly 30 meters, he couldn't climb up either.

Further up is the limestone, which is sticky and smooth. As long as it goes up, it will fall off in minutes.

Ye Cheng no longer bothered about this, and looked towards the middle position.

Looking at it, I immediately found that there was a model of an ancient building hanging upside down in the middle.

The ancient building was exactly the same as the ancient building reflected in the mirror below, just much smaller.

Around the ancient building, there are many mirrors, reflecting the faint light from below, shining on the small ancient building model.

"I see!"

From what he saw with his own eyes, Ye Cheng completely understood the principle here.

He looked around, and sure enough, he saw some shadowy light spots on the surrounding walls. When the flashlight was lit, these light spots were not very conspicuous.

It was only when he looked in the dark that he could see some clues.

After thinking about everything, Ye Cheng climbed down from above.

Everyone rushed up, "How about it, what's on it?"

"Teacher Ye, what's the discovery?"...

The crowd asked in a row.

Ye Cheng replied: "I understand the principle here."

"What's the reason?" Everyone was even more curious, and they stared at Ye Cheng with eager eyes, just like curious babies.

Ye Cheng didn't speak in a hurry, but said to Fatty, "Fatty, go and light that fire pit!"

Ye Cheng knows that the fire is for lighting, and it also turns on the switch to the lower organ, so it must be lit!

Fatty Wang didn't talk nonsense about this, "Okay, I like arson the most!"

Having said that, the guy ran over to find the fire pit and lit it directly.

call…

The flames sprang up in a swish.

From one point, circle the entire cave upwards.

Circle after circle, the scene is a bit spectacular.

Everyone looked up at the fire, and their heads were a little dizzy.

When the fire was completely lit, the entire cave was illuminated as bright as day, and the ancient building in the mirror under the water was also illuminated as if it were daylight.

"It's spectacular."

"Damn, I also want to play with fire, but my mother said that playing with fire will make you pee on the kang, what should I do?"

"Last time we played with fire in our village, and now we still eat free meals in it."

"Yeah, hurry up and explain the principle, Curious Baby is online."

"That's right, if you don't say it, everyone is dying!"

The fire dragon rose up and stopped near the top, and the flames were burning.

When everyone looked up, they vaguely saw that there was something shining on the top of the cave.

However, it was too far away to see what it was.

"There is really something on it, what is it?" Fatty Wang asked curiously!

Xiao Chen covered his eyes with his hands and looked around, squinting his eyes, but he couldn't see clearly.

"It's too far to see clearly!"

Ye Cheng said: "It's an ancient building model that fell down.

Dear, this chapter is not over, there is another page ^0^ model, the reflection in the mirror below is the image of the ancient building model! "

"What, it's that simple?" Fatty Wang was stunned.

Everyone else was stunned, they didn't expect it to be so simple.

However, Li Duoduo said: "No, if it's just a simple reflection, when we cover some positions, the ancient building below can't be complete!"

"Yes, yes, I just wanted to say this. Before, I was underwater and blocked such a large area. However, the reflection of the ancient building is still there. How can I explain this?" Fatty Wang also said!

Everyone also nodded.

If it is really such a simple thing, the ancient buildings below cannot be so complete.

Everyone understands this basic common sense.

Ye Cheng pointed around, "This is actually just a little trick. There was a little magic in ancient Persia. They used a special gemstone to make a mirror. Under the sun, the gemstone will become dull in color, but under the moonlight , the gem will become shiny, and this gem is called the moon stone!"

"And this kind of magical stone?" Fatty Wang was shocked.

No one else has heard of it~www.readwn.com~ but Li Duoduo exclaimed: "So it turns out, it turns out to be the moon stone!"

"What, girl, have you heard of this kind of moon stone?" Fatty Wang asked!

Li Duoduo nodded vigorously, "When I was in school, I heard about this kind of moon stone. The moon stone is an aluminosilicate of sodium and potassium. The two components interact in layers, and the two components can scatter visible light. And understanding that in the face of light interference or diffraction, the combined result is the moonlight effect!"

Basically no one understands what she said, even Ye Cheng doesn't understand these scientific terms, but I have to say that this girl was definitely a scholar when she was in school!

Fatty Wang was even more stunned, "Stop, stop, talk about people, this is nothing, I don't understand Fat Master, let's not say it's so complicated, let's just say it works?"

Li Duoduo was helpless and sighed, the sadness of the scumbag.
