Are there pterosaurs sneaking up from behind us? That's the first thought that pops into our minds. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

The hole in the back is very dark, there is not a single fluorescence here, and if the pterosaurs come around from behind us, they have adapted to this dark environment, it is really the end of us.

Yuan Weichao turned around and lit up the lighter, and we were ready to assassinate the sneak attacker at any time.

The fire lit up and shone at Long Linglong's feet, reassuring that the pterosaur had sneaked up from behind us, but the heart we had just put down rushed up again, Long Linglong's feet were a human skull, and she happened to step into the skeleton's mouth, and the teeth in the skeleton's mouth were still intact, probably the teeth were hanging on her feet.

How could there be a human skull in this underground cavern?

Who is he?

How did you get into this?

Was he eaten by a pterodactyl?

It's all a mystery, and dead people can't speak.

"Hey, how can there be dead people's bones here?" Zhang Shun muttered to himself.

"It's the dead man's soul that became those big birds outside, you didn't hear the brigade commander say, there must be many more inside." Zheng Feng said.

Yuan Weichao inserted a military thorn into the skeleton's eyes and fixed the skeleton, Long Linglong slowly tried to pull out his foot, leaning on the cave wall on the side and being shocked: "Was there a person living in this small hole before?" ”

"If only there were people, and if they had something to eat, we wouldn't be hungry." I said, but I really don't see a bad environment here that is suitable for human habitation, and without sunlight you can't produce food, what does he rely on to make a living? Maybe he, like us, accidentally bumped into this place and died here if he couldn't get out.

"This man is so strange, his mouth is so big." Yuan Weichao said.

As soon as he said that, we paid attention to such a detail, this skeleton's mouth is indeed very large, almost twice the size of a normal human, so Long Linglong's feet will step into it, except for this feature, everything else is the same as an ordinary human.

I haven't heard of or seen someone with such a big mouth, is this a human being? Or the bones of those primates that resemble humans?

"Is this an ape's skull?" The county magistrate also thought of this.

"How did that ape get here? The bare head is what about its body? Zhang Shun asked.

"The body is naturally in the hole, you are stupid!" Zheng Feng said.

"So why is its head here? Could it be that its head fell off its body and ran here on its own. "Zhang Shun is not very stupid.

"It was killed by a youkai and dropped its head here." Zheng Feng said.

"What youkai killed it?" Zhang Shun said.

Zheng Feng was speechless at this time.

"It's not an ape's skull, it's a cranial cavity that is so large, an ape wouldn't have such a large brain capacity." I said, I took a closer look at the back of its head.

"Maybe it's a big-headed ape." Zheng Feng said.

"Let's go in and look for its body, to see if it's a man or an ape, and by the way, to see how he died, and if there's anything to eat in it." I say.

"Could there be demons and monsters in there? Did the demon eat the man and then throw his head outside? Zhang Shun said.

I thought to myself that the demons and monsters are not enough, maybe it is possible that some prehistoric beast is possible, we are running out of ammunition, and it is really difficult to deal with prehistoric beasts.

It's better not to mess around inside.

"There is also a gluttonous ghost living in the dare, it specializes in gnawing dead bones, when it gnaws this skull, when it sees that there is no meat, it gets angry, and throws the skull out in anger, no wonder those thieves and birds dare not enter the hole, there must be something in the depths of this hole, they are afraid." Zheng Feng said.

The skull was indeed left out, and it wouldn't have made it here on its own, but how it got here is still up for further study, so I looked at the skull to see if I could find any clues.

The skull is well preserved, the texture is smooth, but it doesn't feel so hard to the touch, if I use force, I might crush it, I didn't dare to try hard to see if I can crush it, even if it's a skull, it's a respectable person, I drew a line on it with my fingernails, leaving a very obvious mark, yes, it's already soft.

According to archaeological experience, this skull must be at least thousands of years old, because the calcium in it has almost disappeared, and calcium is the most critical element that supports the hardness of bones.

Thousands of years ago in China, when Dayu ruled the water, at what time did this person run here?

"Don't look at it, it won't be your relatives, hurry up and think about how to make a fire and barbecue." Zheng Feng said.

"This is a human being thousands of years ago, there must be some secret in the depths of this cave, maybe the exit is in this hole." I say.

"Thousands of years ago? Do you know the skull of thousands of years ago? You have a wide range of specialties and have studied skulls. Yuan Weichao said.

Long Linglong heard that it was a skull thousands of years ago, and she also squatted down, I heard that she also learned this in foreign countries, but she was quite scared to look at her, maybe she was not mentally ready to deal with these terrifying things.

She fiddled with the skull for a while, and also scratched a long mark on the skull with her fingernails, and said: "That's right, this skull is indeed very old, and the calcium in it is almost evaporated, and it seems that it is not only thousands of years old, but at least more than 10,000 years old." ”

This level of professionalism seems to be higher than mine, but with Long Linglong backing up my statement, they don't choke me anymore.

"10,000 years ago! I don't know what people looked like 10,000 years ago, are they also like us? Zhang Shun said.

"People 10,000 years ago were still primitive societies・・・・・・" When Long Linglong explained primitive humans to them, I got up and used a lighter to carefully study the cave wall.

Sure enough, I found a black arrow-shaped mark, because it was too old, the air in the cave was humid, the arrow had been mottled and very blurred, I wiped it lightly with my clothes, and there was some black powder stuck to the clothes, as if it was carbon.

"Miss Long, what are you looking for?" I asked her to take a look, one is short-minded, and the other is long-witted, not to mention that her professional level seems to be higher than mine.

I lit her with a lighter and showed her the black powder that had been wiped off my clothes.

"That's right, that's what the carbon pen paints, the main ingredient of the carbon pen is graphite, and these black powders are graphite, how is this possible? How could humans 10,000 years ago know how to use graphite? Long Linglong said to herself.

"You see that the arrow is pointing to the depths of the cave, as if the depths of the cave are some kind of place, there should be no demons and monsters." I analyzed.
