The interior of the house was simple, with nothing but a bed, table, and stool made of black stone.

Because the things on the bed and table do not know how many years have passed, in this place where there is oxygen has been infinitely oxidized and weathered, it has already turned into powder.

The most attractive thing for us is the everlasting lamp at the head of the bed, which is still there.

But the light of this ever-bright lamp seems to be very dim and weird.

It is said that the light of the oil lamp will flicker on and off as the air burns, but why is the light of this ever-bright lamp like a light bulb, a constant brightness?

The lights in the room were too dim, so we approached the lantern with a flashlight and carefully observed its longevity principle.

It seems that this lantern should also be made of stone, otherwise it would have been oxidized and weathered into powder after a long time.

But I don't know what material it is, but the lamp is completely black, and it is even darker than the black stone objects in the house!

The lamp did not contain any special oil or fuel, but a shiny stone.

It emits a constant light source that illuminates the room, albeit not very bright.

"Luminite?" Fan Ping exclaimed in surprise, as if he had found a treasure, and reached out to get the stone.

I grabbed Fan Ping's hand, stared at the lantern and said, "Don't touch it!" ”

Xiaohua nodded on the side and said, "Although I don't know why, I feel that this stone is indeed very weird!" Except for the stone stuff in the house, everything else has basically turned into a powder flocculent, it seems that the things here have existed for at least a thousand years, and the stone still keeps shiny, I really don't know what material this stone is made of? ”

Fan Ping shook off my hand, turned his head and sat on the stone bench, and began to rummage through the food in his backpack, while complaining: "What's weird, I think you're weird!" It has existed here for thousands of years, indicating that this stone was discovered thousands of years ago and used it to illuminate the dark abyss. ”

I pulled Xiaohua and sat on the stone bench, and said thoughtfully: "If I guess correctly, this stone should be fluorite, also known as fluorine." It contains rare earth elements, and most of the pearls of the night in ancient times were made of fluorite.

Xiaohua said with a surprised face: "Fluorite? Rare earth elements? Hydrogen fluoride? ”

After turning my head to look at the lantern, I nodded to Xiaohua and said, "Yes, and according to the brightness of this stone, the content should be high!" ”

Fan Ping was eating compressed biscuits with relish, and when he heard us discuss the words "hydrogen fluoride", he was stunned, and the biscuits in his hand also fell to the ground, it seems that he also knows that hydrogen fluoride is highly toxic!

After Xiaohua saw Fan Ping's stupid appearance, she patted him with a smile and said, "Hydrogen fluoride is indeed highly toxic, but as long as you don't touch it, it's fine, haha, coward!" ”

After Fan Ping heard this, the biscuits that were not chewed in his mouth resumed chewing again, and then smiled awkwardly at Xiaohua.

I looked at the innocent Xiaohua and the silly Fan Ping, and barely squeezed out a little cooperative smile on my face.

But I didn't laugh in my heart at all, because I had a truth that I didn't tell both of them personally!

In fact, fluorite luminescence requires a prerequisite, that is, it will only emit light after being irradiated with ultraviolet or cathode rays.

And these fluorites can shine here for thousands of years, indicating that the entire dark abyss has been covered with ultraviolet rays or cathode rays!

I know that as long as we don't stay here for a long time, the damage to our body from ultraviolet rays or cathode rays is not very great.

But if I tell them the truth, Fan Ping will inevitably be afraid and panic, and Xiaohua will blindly seek her father because of guilt.

In that case, we would inevitably be in a mess, so after much deliberation, I finally chose to hide it from both of them.

In this moment of rest and thoughts, I suddenly remembered the continuous gunfire from Uncle Biao's team, and I wonder what kind of danger they encountered?

I don't know who the distress message sent to Xiaohua's pager is?

I don't know if this abyss is the end, maybe this is just the beginning?
