With a sigh, Laikaon quickly swung the axe in his hand, wanting to cut the road around him more widely. But soon, he found out that it was a thankless task. His body was already huge, and with the size of the double-edged axe, in such a small space, there was not even room to swing the axe. So, no matter how sharp the axe is, or how liliang Lecaon is, carving out a path suitable for his actions in this environment is a luxury in itself.

Xiao Yan on the other side did not answer Laikaon's request, and in the depths of the cave, the young trialist had already rekindled the fire fold, and there, he seemed to have discovered something.

Thanks to the widening of the hole when Laikaon squeezed down, more light shone in, and there seemed to be some reflections on the ground, so Xiao Yan accidentally found some images at the beginning of the crack.

"What's that?"

Calristo walked out and asked in a low voice to the image Xiao Yan was looking at.

Xiao Yan shook his head and replied, "It's not very clear, but it looks like a construction drawing, a primitive construction drawing." ”

Subconsciously reaching out and touching these images, Xiao Yan continued: "The images engraved in, and then the color was smeared on the nicks, and there was no special polishing, but there didn't seem to be any polishing tools in that era." ”

Calristo looked at the image and whispered, "It's more like a guide, you see, we're probably here right now, the entrance to this cave, this cave, oh, if the image is about the same scale, that's huge." ”

Xiao Yan shook his head and said, "Don't think that the humans of that era can master how advanced the scale is. It's not so much a guide map. It's better to say. This is a construction progress map. ”

After a pause, Xiao Yan continued: "At first, only a small number of people lived in this cave, and as the population increased, they did not go out to find new caves, but dug into the cave. Dig until the location where the red trail ends. ”

"Then, perhaps after the cave could not satisfy the larger population, the inhabitants of the cave began to dig in again and again, which were the red lines. The cave was further expanded. There is a certain difference in the color of the two line segments, and they should not be pigments from the same period, so it can be inferred in this way. ”

"After that, the cave was enlarged three more times, until it reached the purple line, and finally stopped."

Xiao Yan explained in a low voice, the voice echoing back and forth in the quiet cave, and finally turned into a whisper of a breeze that didn't know what to say, passing through the ears of Laikaon, who had just squeezed in.

Calristo frowned and asked, "It's a strange thing, to be able to keep hollowing out the cave." And to be able to keep the entire cave from collapsing, with such strong civil engineering ability and engineering knowledge. I didn't leave this cave and went to Shijie outside, and the humans who live here seem to be very afraid of Shijie outside. ”

Xiao Yan nodded and said, "Listening to you say this, it's true, being able to keep digging these caves, but not daring to leave the caves, and the population is still growing, this kind of thing sounds very incredible, it makes people feel."

"Absurd," Calisto interrupted, "this is an absurd race, advanced enough to excavate this complex stony environment, and the population has been increasing all the time, and then it all ends abruptly, what are they running away from?" Or is there something in this cave? ”

Laikaon also lit a torch drawn from the ring, shook it from side to side, then looked at the ground and suddenly said, "Maybe I know what they're running away from." ”

Seeing Xiao Yan and them turn their heads, Laikaon continued, "Disasters, floods, or glaciers, only more and more people will come in, and no one will leave here. The greatest possibility is the Great Flood, which is mentioned in almost all human legends, and Huaxia is no exception. If there is a great flood outside that obscures everything, it can be well explained that no one has left this cave in weishenme, and people outside are still coming in. Quite simply, these refugees have nowhere to go. ”

Xiao Yan frowned, he had no opinion on Laikaon's statement, unless the environment outside was very harsh, the humans here would not keep digging into the cave.

And the great flood, which is famous in the history of mankind and is the catastrophe that destroyed the world, can indeed play such a role.

In fact, whether it is Noah's Ark or other legends, the survivors who escaped the Great Flood lived in a place very similar to the huge cave where Xiao Yan is now.

Of course, this idea of Laikaon would be more perfect if it could solve the source of food for the humans who live here. However, Xiao Yan didn't care about these perfections, he looked at the picture in front of him, and calculated the width of the Yanshan Mountain Range under the Great Wall in his heart. After a while, he frowned and said, "This cave is not excavated horizontally, but constantly obliquely, going deep into the ground, otherwise it will dig through this mountain, but the specific situation will be found out if you go in and continue to see." ”

The three of them turned around together, the torch in their hands kept jumping, and various images on the surrounding cave walls appeared more and more in their eyes, most of those images were pictures of some people constantly digging caves, and occasionally some hunting images. However, the targets of these hunts appear to have come from caves, and there is even an image of an animal poking its head out of a rock wall to attack humans. What's even more peculiar is that in the center of this image is a huge hole, about the thickness of two lycaons. This big hole is more than ten meters above the ground, diagonally facing Xiao Yan and them, and they don't know where this big hole will eventually lead.

There are also some hunting images, and humans are hunting some huge animals, and these huge animals actually appear from the depths of the cave, and there is an indescribable grotesqueness.

In addition, all the animals they hunted were very strange, at least Xiao Yan couldn't recognize even a real animal from these animal images, although these animals were very clearly depicted, but Xiao Yan they just didn't know what they were.

As the cave grew larger and larger, Lecaon walked more and more easily, and finally he looked at the roof of the cave above his head and suddenly asked, "Look, what is that?" ”

Xiao Yan looked up suddenly, and under the illumination of the light, a black shadow above his head made his heart jump suddenly.

It was a snake, to be exact, a black snake trapped in a huge amber, this snake was very huge, and it was unusually coiled in a circle, and finally the snake was headed down, with a huge snake mouth, and looked at Xiao Yan viciously.

According to Xiao Yan's estimate, the snake was at least 10 meters long, and the black scales on its body were constantly turbulent under the light of the jumping fire, and at a sudden glance, it seemed that the snake was still alive. However, what Xiao Yan cares about more is that in the middle of this snake's mouth, there seems to be a human head. Because the snake body was wrapped in heavy pale yellow pine resin, the light could not penetrate it, and it was really impossible to see if there was such a human head, but Xiao Yan could feel that the human head seemed to be silently watching them.

This strange sight made Xiao Yan stand for a while, and said in a low voice, "No, something is wrong. ”

Calristo turned his head to look at him and said, "You can see it too, don't you, this amber is completely man-made, and it is impossible for a normal snake to coil into a whole so regularly, not to mention that it happened to be wrapped in pine resin at this time, and there was no change in its body." ”

Xiao Yan nodded and said, "The humans who lived here at that time should have been very strong, although the environment outside was very bad, but in this cave, they were almost invincible, the question is this, how long have they stayed in this cave?" I always had a hunch that they never left the cave, but perished in it. And with them perished were these strange creatures. ”

The three of them are not archaeologists, and they can only infer from their own feelings about the situation in front of them, and no one knows if they will deviate from the topic, so in this case, it is more likely to trust intuition rather than vision.

After looking at this strange black snake, the three of them quickly walked to the image that Calristo had just seen, and by this time, the three of them finally saw the entire image clearly.

Carristo was right, the humans around this image are very delicately depicted, not the kind of simple lines, the image is very full, although it is not realistic, but it unnaturally exudes a strange atmosphere.

Sadness, despair, pain, and relief.

Around the long, two-horned monster in the center, a total of 6 humans are depicted in the entire pattern. The human on the right of the pattern did not look at the monster, but turned his head to cover his eyes with his hands, presumably crying, and many small holes symbolizing water droplets appeared in front of the human. Above the pattern, two humans are dressed in strange clothes, what appears to be armor, and they hold crossbow-like weapons in their hands, but the two men face each other and seem to be going on and arguing. The human on the left of the image is kneeling on the ground, also reaching out to the sky. The two humans below the pattern are too indistinguishable to be identified, but one appears to be preparing to approach the monster.

Xiao Yan looked at the picture carefully, and then walked a few meters inside, looking left and right. As with his previous infrared vision, after this picture, there was no new pattern on the cave wall behind it. (To be continued......)
