Everyone tentatively walked into this glowing stone chamber, feeling a little inexplicable. The fluorescent fluorescence that flickered everywhere in the pen www.biquge.info was like a big name for everyone.

"What......'s going on, what the hell is going on, and why do these stone slabs shine......" Xiao Hachi asked a little confused.

For this question, everyone is also unclear at this time. Because the devil knows why these stone slabs shine.

"Hmm...... Could it be ...... Could it be that this could be some glow-in-the-dark stone ......?" Er Lei said thoughtfully.

"Huh, glow-in-the-dark ......?" everyone wondered.

In fact, this glow-in-the-dark stone is actually not new to everyone. And everyone was surprised at this time - there is such a large amount of luminous stone here, and such a large underground palace was built out of luminous stone!

And speaking of this luminous stone, everyone has seen or heard of it more or less. It is nothing more than a stone that can shine at night. Most of the stones that can shine at night are high-tech self-luminous products such as alkaline earth aluminate and silicate activated by rare earth elements. However, if this kind of luminous stone wants to fluoresce at night, there must be a prerequisite, that is, before it can emit light, it must first absorb a certain amount of bright light, such as sunlight. Otherwise, it will only be difficult for a good woman to cook without rice.

"But...... That's not right......" Ye Qiu said puzzled. What he meant was that this dungeon was located more than a thousand meters underground, so how could there be any light source for this luminous stone to absorb?

"Not necessarily...... As far as I know, there is a kind of stone in this world that can shine on its own......" Xiao Qian said slowly......

......

Indeed, in this natural world, there is indeed a stone that can shine on its own. For example, fluorite. It is the so-called pearl of the night.

Speaking of this pearl of the night, everyone is naturally no stranger. Although it is only from the book or the movie, in fact, there are such things in the world.

Night pearl is a rare gemstone, known as "with the pearl", "hanging pearl", "weeping thorn", "bright moon pearl" and so on. Usually the night pearl refers to the glowstone.

And this fluorite is formed by some luminescent materials in the earth's interior after tens of millions of years, from the initial volcanic magma eruption to the later geological movement, which is formed in the ore. And the stones containing these luminous and rare elements, after processing, become what people call the pearl of the night.

Today, the "Pearl of the Night" refers to the natural and self-luminous jewels that can be seen by the human eye in the dark......

......

"Oh...... I see. This huge stone chamber was originally built with the pearl of the night......" everyone said, as if they understood everything.

However, in less than half a second, everyone almost turned their backs!

"What?!!How is this possible?!" Dalong exclaimed first. It means that I don't go to school, don't lie to me. With such a large stone room, you dare to tell Lao Tzu that it was built with the pearl of the night?! You go to the grave to burn firewood -- even the newspaper is saved!

That's right, Dalong was right. Even if there is indeed such a generous and bold person in this world who is so corrupt and willing to be the head of this wrong, then there must be such a large number of night pearls for him to corrupt, right? You must know that this night pearl is not Narafi, and it can never be bought with money!

Not to mention anything else, what is known to all is that the Queen Mother of the West Lafayette is rich, isn't it? That's quite rich! What Boss Li, Boss Ma, Boss Billgai, in front of Lafayette, are all floating clouds. But even if she is as rich as her old man, she will only have such a night pearl in her life. And after death, I had to hold the night pearl in my mouth before I was willing to bury it.

Of course, if the artificial luminous pearls on the market are also counted, this matter has to be talked about......

......

And right now, this huge underground palace stone room actually looks like it was built with the pearl of that night?

But now this fact is in front of you! The surface of the whole stone chamber is indeed emitting a soft but shining light at this time. It's a little dizzy, but it feels indescribably comfortable.

And the substance that can emit light on its own in the darkness is still the same sentence, only the fluorite, that is, the pearl of the night......

......

Dalong was a little anxious. So he took out a pickaxe from his satchel and prepared to find a gap and chisel a piece of it to see what was going on. But it was only at this time, when the great dragon was looking around for the gap between the glowing stone slabs, that he realized that there were no gaps between the stone slabs. And the gaps between the slates, which were mistaken by everyone before, are actually just the darker textures in the slate!

In other words, this entire huge stone chamber could not be carved from a whole night pearl?!!!

People no longer dare to imagine it, because this matter is beyond the scope of human understanding!

God!!

How is this possible???!!!

However, although the dragon jumped up and down and ran almost all over the stone chamber, he was never able to find a single gap! Not only that, but at this time, under careful observation by everyone, they actually found that this stone chamber seemed to be an irregular oval!

That is to say, the group at this time seems to be in the hollow of a giant night pearl!!

God!!

How is this still possible?!!!

The dragon collapsed completely......

......

But after the collapse, Dalong is still crippled!

"Damn, you think you can't find a gap, I can't help you, right?!...... I rely on !!" Dalong shouted, then shook the pickaxe and smashed it directly on the spot!

The crowd wanted to stop him, but it was too late!

Again, those with long beards are not necessarily bandits. But this bandit has that beard nine times out of ten...... (To be continued.) )
