Surprisingly, this second passage is more featureless than the first, there is not even a trace of artificiality, it is a natural cave passage, which is also diagonally downward, fortunately, the passage is still relatively wide, even if two people are side by side, it will not seem crowded. Pen ~ fun ~ pavilion www.biquge.info

It took us almost three hours to finish, and at last there was no way - because at the end of the passage was a bottomless abyss!

The exit of that passage is actually on the cliff wall, no matter what direction we use the light to shine, we can't see the edge, we can't see the top and the bottom, and we don't know how high this cliff is, and in front of the cave exit, there is endless darkness!

The lights can't shine through anymore!

In desperation, everyone had to give up and return the way they came.

Back at the fork in the road, we were left with the last passage that we had not yet walked, that is, the passage that the scientific expedition team had entered.

This one took up most of our time back and forth, and if it weren't for the large number of people and the good atmosphere, I would have been unable to bear it.

After a bite to eat, we packed up again and began to enter the passage that was full of anticipation.

But this time, because it was the last tunnel, there was no need to go our separate ways.

The passage was relatively wide at the beginning of a few dozen meters, but after about fifty meters, it became very narrow, and finally only one person could barely pass through.

One by one, several people slowly walked inside.

Except for Hong Kaiyuan, everyone didn't speak: "Damn, this is the rhythm of torturing fat people!"

"If I don't lose weight when I go back, I'm a grandson!

When Hong Kaiyuan finally squeezed out this short slit-like passage, he began to complain again.

Everyone laughed.

As we passed through this narrow tunnel, we didn't find anything suspicious, except for a lot of blackened bloodstains that told us that there had indeed been an accident here.

After walking, I found that this narrow tunnel is more than 200 meters long, and after passing through this section, the passage behind it is much wider, and it is almost as wide as the entrance.

I've always been a big smoker, and as soon as I saw that the space was much larger, I immediately lit one and rested against the cave wall, and the weapons and equipment on my body were too heavy.

Before I could take a few puffs, I heard Gu Xin call me in front: "Brother, come over and take a look, there are a lot of paintings here!"

When I heard this, I immediately rushed over.

I saw that less than ten meters away from the place where I was resting just now, the side wall of the wide passage was actually covered with petroglyphs!

These petroglyphs are not only smooth and clear, but they are also painted, but they are all the single pigment of vermilion. The petroglyphs here are almost as well preserved as those in the first passage, and there is no weathering and erosion.

On a trip to the Northeast a few years ago, I had already seen those petroglyphs, and those petroglyphs mainly told a story, and they were relatively easy to understand.

But the petroglyphs in front of me are a little different, and the contents of the petroglyphs on both sides of the passage describe a certain thing, because I found that there are many of the same things repeating on them.

Looking at the content of the painting, it seems to be very coherent, and the entire cave wall seems to be recording something.

In order to make it easy for everyone to understand and browse, for the time being, the contents of these petroglyphs will be explained according to the scene.

On the cave wall on the right, the first scene has a human-like drawing on it, but the body is not visible, because the head is only drawn in small circles, and the hands, feet, and body are all represented by lines, so the gender cannot be seen.

Looking at the lines, the formation of this painting is similar to that of the cave in the northeast between me, and even the style is somewhat similar.

The picture is divided into two parts, the bottom is painted with a number of people kneeling on the ground, as if they are kneeling down to something, and there are many lines like clouds painted on the top, and there is a long strip of animal-like things, a bit like snakes, and a bit like dragons.

It is said to look like a snake because it is sinuous and twisted, and it is said to be like a dragon because it resembles a dragon head in Chinese mythology at the front end, but it has no horns and no whiskers, but it is somewhat like a crocodile's head.

It has no claws, a pair of wings on both sides, the wings are not large, and there are many square and round patterns on the body, which are far-fetched to say like dragon scales, but their spacing is much larger than the scale spacing of our common dragon patterns, but it is very similar to the porthole of an airplane.

It looks like it's flying out of the clouds in the sky.

Xiong Qianqian screamed when she saw it: "This seems to be a dragon!"

"I don't think so, dragons have horns and claws, and this thing doesn't!" Xiao Lan on the side continued.

Hong Kaiyuan spoke at this time, and he always spoke amazingly: "This is clearly some kind of flying machine descending from the sky, and the pattern below seems to be that the human beings on the earth are kneeling down to welcome its arrival!"

"I feel like a flying machine, not like a dragon. Xiong Ying said.

After they said it, I also felt that it didn't look like a dragon, although I had also seen the so-called divine dragon in the Gonggong Rock, but it was a bit far-fetched to say that it was some kind of flying machine. Because I can see the dragon with my own eyes, how to look at it, the scales are still scales, and the gap between this thing and the window is huge.

I always think that this thing should be caused by the difference in the level of the painter, or the difference in understanding.

The painting on the wall of this cave may be some kind of flying animal in ancient times, but after thinking about it for a long time, I can't tell which animal it is.

For a while, everyone began to talk again, but to no avail.

I frowned, the thing on this painting is very similar to the thing I saw in the Gonggong Rock back then, but I don't think it looks very similar, could it be that the painter who described this thing didn't describe it clearly? I muttered in my heart, but I didn't say anything.

I ignored them and started watching the second scene on my own.

This scene depicts a large number of people surrounding a tall "humanoid", I don't know what they are doing, this tall humanoid has a huge head, but its head is elongated, with two large oval eyes-like patterns, accounting for more than 60% of its face, the nose position is only two points, the mouth is large, it is ajar, as if talking to the people around it.

Further down the road, the third scene shows three or four people tapping something on something, the fourth scene shows seven or eight people building a house on a big tree, the fifth one shows three or four people throwing a bunch of curves with a grid-like thing, the sixth scene shows a bunch of people jumping around a regular triangle of many curves, similar to a dance, the seventh one seems to be hunting, and then a bunch of people are celebrating something, and many more, I was confused.

It wasn't until I saw the ninth and last scene that I felt very familiar, that it was clearly a person plowing the field, because there was a cow in the front of the picture, and a person in the back, holding an object in one hand and raising it, and putting the other hand on an object similar to a plow behind the ox.

Suddenly, I heard Hong Kaiyuan shouting loudly: "Damn, I only understood after reading it, it turned out to be like this, this is clearly a record of human history." ”

Then he introduced to everyone from the end, and his views were quickly agreed by everyone.

But I thought of another thing: the people who painted these petroglyphs, did their purpose coincide?

Hong Kaiyuan didn't notice that I was distracted and continued his performance.

He starts backwards from the last scene, the last one is farming, followed by learning, hunting, making fire, fishing, nesting, toolmaking, teaching, and descending. On the whole, it is a species alien to another species, and it is it that teaches human beings related survival methods, knowledge and technology, and so on.

It's a piece of history carved into the wall!
