Li Duoduo's technical terms are obviously not understood by many people, even if these people except Fatty Wang have a high degree of education, they are only limited to knowing some common sense chemicals.

They all involve sodium-potassium aluminosilicates, which I have never learned before.

Li Duoduo was helpless and looked at Ye Cheng, "Brother Ye, it's up to you."

Ye Cheng nodded, "It's actually very simple, a gem can only reflect a dim cyan light. If the light is too strong, it will be the same as a stone, and it will be difficult to find. The stronger the light, the lower its reflectivity, the less likely it will be. Conspicuous, and in bright light, our eyes will only notice bright things, so it's more difficult to spot!"

Fatty Wang nodded thoughtfully, as if he understood, but as if he didn't understand, "Wait, this thing can reflect turquoise light, so the ancient buildings in this mirror are turquoise, but, it seems, there are also Where is the problem?"

He felt something was wrong, but he couldn't remember what was wrong.

Li Duoduo said: "It's light, why can a faint light make the ancient building clearly reflected in the mirror?"

"Yes, yes, this doesn't make sense!" Fatty Wang nodded immediately.

Ye Cheng continued: "This is even simpler, the mirror in the water is a light concentrator, when our flashlight hits the mirror, the light hits the top of the cave vertically, and then the small circles around the ancient building model The mirrors reflect off the countless number of these moonstone mirrors on the wall."

"The reflected light of a single mirror is extremely weak and almost imperceptible, but many mirrors reflect countless light, which can reflect the ancient building above on the mirror surface of the ancient mirror in the water. Because it is three hundred and sixty degrees of countless light A superposition of weak reflections, so no matter where we are, we don't have a shadow on the mirror."

"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."

"To put it simply, this is a bit like a shadowless lamp used in surgery, the principle is the same!"

Speaking of which, Fatty Wang patted his thigh.

"Hey, shadowless lamp, I know this fat man. It was written in the textbook when I was a child that Comrade Bethune used the shadowless lamp to perform surgery on people. If I said that earlier, did I understand fat master sooner!" !

"It turns out that the principle is so simple!"

Others also came to their senses.

No one would have thought that the principle of something that made them inconceivable and did not understand was so simple.

This is equivalent to these modern people, who were confused by the ancient people's use of science and technology. It is a bit embarrassing to think about it.

"I rub it, so it turns out, it's awesome, it's awesome in capital letters, and it's for the Zhang family."

"It seems that it's not unreasonable for me to be so smart. My ancestors used to be very good."

"666, in the Ming Dynasty, I figured out how to play with optics. Who cares, how many years ahead of the West."

"Hey, the most advanced technologies of the Dragon Kingdom are all used in the ancient tombs, and the advanced technologies from abroad are used in the society and people's livelihood. This may be the reason why the Dragon Kingdom is backward in modern times!"…

"It turned out to be the result of shadowless lamps and reflections. However, this moon stone is a bit interesting, and I will play it very quickly."

Ye Cheng's explanation immediately made people feel enlightened, but almost everyone with a bit of cultural common sense understood it.

After thinking about it, in fact, they just think too much.

Li Duoduo thought for a while and asked: "But, the Zhang family made such a thing, is it difficult to scare people or confuse people? It doesn't seem to have any special meaning. Even if we come here, we will not be frightened. It's just that it's a little weird!"

Fatty Wang muttered: "Damn, it's not **** scary, he's disgusting, look, haven't we studied here for so long?"

Ye Cheng said: "I guess, this is probably used for lighting. It is not a small project to build such an ancient building underground. It is impossible to use grease for lighting all the time. I guess, there should be one above it. Reflectors, reflect sunlight in during the day!"

"But it's likely that the reflector above has been damaged due to too much time."

Li Duoduo nodded, thinking it made sense, "If that's the case, it's true that the light source from the outside world is the common light source, and these oils should only be considered as backup light sources."

Fatty Wang didn't care about that, "I don't care what he uses as a spare. What should I do now? I've seen it. There are no other passages here. Where is the ancient building hidden?"

thump…

As soon as Fatty Wang finished speaking, there was a loud noise from Shimen's position.

Everyone hurriedly looked over, only to see that the thick stone gate was knocked out of dense cracks!

"No, the ancestor of Milotuo has caught up!" Fatty Wang shouted.

In an instant, everyone was nervous.

Although there are weapons in hand, it is definitely not an easy task to deal with such a big man.

If it was bombed with grenades and explosives, it would definitely destroy this place.

Unless absolutely necessary, it is not allowed to use.

"Mr. Ye, what should I do? Hurry up and think of a way." Xiao Chen was so anxious that he was about to cry again.

Fatty Wang gets angry when he sees him, and when he goes up, he just kicks.

But Xiao Chen had expected it a long time ago, and hurriedly ducked to the side.

Fatty Wang's kick was empty, and he almost missed a big split.

Dear, this chapter is not over, and there is another page ^0^ that made Fatty Wang furious.

"Mr. Ye, help!" Xiao Chen hurriedly hid behind Ye Cheng.

Ye Cheng glared at Fatty Wang, "What time is it, you are still making a fool of yourself, since this is a place for lighting, there must be a passage to the ancient building!"

"But, where is this passage, there are stone walls all around it, it doesn't seem like there is any mechanism to arrange it!" Fatty Wang said!

He is not stupid, on the contrary is very experienced.

When I first came in, I looked at the surroundings.

All are irregular stone walls, although there are traces of artificial excavation, but it is obviously impossible to set up a secret mechanism in such a place.

Otherwise, the stone gate would not have been repaired so obviously.

thump…

Another loud noise~www.readwn.com~ The dust and gravel rustled from the stone door, and it was about to be completely shattered. It was estimated that it would not be able to withstand the savage collision of Milotuo.

And just then, something strange happened again.

The spiral flame suddenly became smaller and smaller, as if it was about to go out.

Fatty Wang scolded: "Fuck, this is a **** big guy who lights candles and blows the lights."

Ye Cheng was speechless, this fat man is really not stingy, it's such a time, and Nima is thinking about this.

"Hey, what's going on? Has the oil burned out?" Team Zhang and the others were also a little flustered, feeling extraordinarily hopeless.

These changes are certainly not without reason, but indicate that something is going to happen.
