The stairs have been extending to the bottom, and they don't know how deep it is, but fortunately there are no forks, and they don't have to worry about any changes, just keep walking towards the bottom, but this distance is still farther than they thought, and they still haven't seen the exit after walking for a long time.

But they don't have any other choice, they can only move forward to the bottom, the road ahead is long, they have only one goal, the three of them can also be together without exploring separately, so the chance of survival is still very large, there are many people, and there is a lot of strength, and I don't know what the problem will be when separated.

This passage is not a pure white wall, but pure black, and the color outside is in a very sharp contrast, Liu Xuan and the three of them really don't understand, what is the culture of this civilization, they always like to do something with such a big difference in color, but this is not the point for them.

The point is that there are still some words on these walls, and the same as the words in their hands, they still can't read it, they can only watch these books continue to walk down, between different civilizations, it is simply more difficult to communicate with words, linguists can't understand things, the three of them can only look at it, as for what it means, it's not their ability to solve it.

But soon something came out that attracted them. The most likely way for two cultures and civilizations to communicate with each other is through patterns, and as they descend, patterns gradually appear on the walls that were originally full of text, as if these civilizations are doing something here.

Although the pattern is more common among civilizations, they can't understand what it means when they don't know what the other party's location looks like. Take a very small pattern on the top as an example, the above painting is the scene that Liu Xuan and the three people just saw outside, that is, the low black houses and the three towering buildings outside.

Assuming they hadn't seen this thing, they wouldn't have imagined the real use of these little black rooms when they suddenly saw this pattern. This is also the difference between the two civilizations, and the language barrier is also based on the fact that their world is not the same.

The original text can be skipped directly because they can't understand it, and when they encounter these patterns that can be understood, they still need to look at it, which seems to record a history of this civilization, and the three of them also agree that they may find some valuable information on it. So they also stopped descending for a while and looked at the patterns carefully.

Gradually, they also saw that a piece of the history of this civilization was coming, but the content of this history made them a little puzzled, because it was not very consistent with some of the things they had seen with their own eyes.

There are a lot of patterns, but most of them have never seen them, and even if they have these patterns, the three of them may not be able to understand them, and when they see the end, they see a headache, and they see that they can't waste any more time

Wait, they are the ones who understand the specific meaning of the three patterns.

One is a history of the destruction of the planet:

A long, long time ago, when this civilization had not yet developed, their buildings were built on the surface of this planet, but one day, a lot of flying things appeared in the sky and landed on the surface of this planet, and a piece of history came to an end.

It should be that there is an alien civilization to prevent the stable development of this civilization, and they want to completely destroy this civilization by force, but they still miscalculated after all, after the artillery fire was cut off and the surface of the planet was completely destroyed, there were still some creatures that survived, and the original civilization on this planet was also among them.

The above also explains the history of the later struggle of this planet, but some Liu Xuan has gradually lost his understanding, and has always seen that this civilization finally gave up the development of the surface and began to move into the underground for the development of civilization, which is many years after the destruction of the buildings on the surface.

When they understood this, Liu Xuan and the three of them were all happy, and it seemed that what they thought at the beginning was not wrong. At the bottom of this place is really the core of this civilization, and the outside is just an illusion of this planet, and the real building is actually under this planet. 【#¥Aichi Literature ~... Fastest update]

When confirming the news, Liu Xuan was also a little speechless. Is this underground really that good? I think that the mysterious planet civilization at that time also built its own buildings under the ground in disguise. The same is true of this advanced civilization, is it possible that every advanced civilization is a caveman? It's unlikely.

In short, compared to the complex environment outside, hiding underground is also a good choice, anyway, a planet is still quite strong, using the surface of the planet as a new defense, it is also a very good choice, in the early stage of civilization development, the protection provided by the planet is also quite powerful.

This was the first thing they understood, and through this they finally confirmed their conjecture. In this way, it is almost certain that if you continue to walk downward, you should be able to reach the real place where this civilization is, where there may be something they need.

But this also brings some questions, the biggest question is the situation on the surface of this planet, at the beginning, this mural is also clear, they have withstood the blow of alien civilization, all the buildings on the surface are destroyed, turned into ruins, but this is very different from the real scene outside.

What they saw outside was a forest. There are many species, green forests, where there are broken walls, even ordinary cement buildings, after being destroyed for many years, you can see a little ruins. But there's really nothing you can't see outside, could it be that this civilization has been specially cleaned up. It doesn't make sense.

Change your residence to the ground, and the things on it will not affect their lives, and there is no need to clean it up.

According to the scale of the ruins shown in the picture, according to their productivity level at that time, there is no way to clean up in hundreds of years, which is simply not a worthwhile choice for the people and money.

Just like the original earth civilization, some waste materials are landfilled, and when the people of this civilization enter the ground, the surface of the earth is the underground of the earth civilization for them, and throwing garbage on it is the best choice. The three of them are puzzled by this. But it doesn't matter, it doesn't affect them very much.

The second thing is about the buildings outside, the above is also described in quite detail, generally speaking, it is similar to what Liu Xuan and the three people guessed, those small low black houses outside are indeed their purpose, to be precise, there are no living people on the surface, they are all people of advanced civilization who have died in battle.

According to the meaning of the mural, Liu Xuan summed up a sentence: Only those who sacrifice for the righteousness of civilization are eligible to be buried outside the planet, maybe this is the traditional custom of this civilization, but it is also a thing that makes them uncomfortable.

That's about this passage, to be precise, it's not the right way to get into the Underground City, and there are better and more formal ways to get into the Underground City. And there are some high-tech existences in it, so you don't have to rely on yourself to go on.

It would not be an exaggeration to say that this passage was to be described as a "burial passage" in the language of the earth, because the place itself was used to transport the coffins of those who had fallen in battle. Presumably the civilization itself thinks, for their heroes. Sending them to the ground step by step is a sign of respect for them.

As for the three tall white buildings in the center, they are indeed solid. The entrance of this passage itself is not on top of the three white buildings, but somewhere else, but this civilization used spatial technology to teleport the three of them to this place, and they can be regarded as shit luck.

The three white buildings also represent the planet itself, and the tombs of heroes surround the planet they have fought for all their lives, and they can also sleep peacefully. In fact, these ideas are similar to the "falling leaves returning to the roots" of the earth's civilization. It's just that their home is the planet itself, and there is no difference anywhere.

Many doubts were solved by this mural, and there was no reason for Liu Xuan and the three of them to stay here. Continue to the bottom of the line, and according to the order of this mural and the time they have been walking, they should be almost there, and they are still not far from the last place.

On the way, Qin Ming also asked a very puzzling thing: why did this civilization burn these things on this wall, instead of putting these data in some storage place, so that maybe they could still know more things. After all, there is very little that the mural can show.

The murals here aren't colorful, ten

The clear murals are not painted on the wall, but are really engraved on the wall, saying that they are murals, and the real situation is just a few quite simple lines, which are similar to the ancient civilizations of the original earth, and they are the most basic elements, very rough lines.

Liu Xuan will have an explanation for this matter, and the reason itself is quite simple, because it is engraved on the stone for the longest period of preservation. He had also seen the stone in this place, it was definitely very hard, and as long as the stone was still there, the message they left behind would not disappear.

According to rough estimates, it is also possible to preserve hundreds of millions of years, and the most primitive things will also have the most primitive wisdom. Some ancient technologies seem to be quite backward, but in fact, there are some places where modern technology will not be able to catch up. For example, the technology for storing this information.

The three of them continued to move towards the bottom, and at that time, Liu Xuan still wanted to get in touch with Wang Meng on the spaceship, but when he turned on his device, he was confused, this place turned out to be a very powerful shielding device, and they had no way to get in touch with Wang Meng. This is quite a troublesome matter.

But even so, there is no way for them to go back, they are transferred by this civilization space, and it is even more difficult to get out, they can only wait for them to complete their tasks. The three of them can only move on, and it is better to save a little time now or a little time.

They don't know what the situation is outside now, if Wang Meng is alone on the spaceship, the consequences are simply unimaginable, the three of them unconsciously speed up their pace as soon as they think of this, and walk down, even if there is any new mural on the wall, they try not to look at it. Just glance at it, and continue to move forward, racing against time.

I don't know how long it took to walk for many times, but there was finally an arch-shaped exit not far in front of me, and the light inside was completely different from the outside, and the three of them couldn't help but speed up their pace and move towards that side. It's like seeing a glimmer of light in the darkness after watching for a long time, and the three of them are like hungry wolves pounced on food.

The light instantly filled their eyeballs, and the sudden increase in light also made them a little uncomfortable, and they all narrowed their eyes slightly. After their eyes adjusted, the three of them opened their mouths wide at the same time, which was still different from what they thought.

There are ruins inside, real ruins, they are very ruins as far as the eye can see, but just looking at these ruins, you can also think of how developed this civilization was, originally Liu Xuan thought that under the protection of this planet, there should be no problems with the architecture of this civilization, but this result made him not very easy to accept.

But since they have arrived here, they can only walk forward, there are still some similarities between this place and the mysterious planet, they are all the same ruins, but what Liu Xuan wants to know more is that the place they want to find is the place

What was waiting for them?

They don't have a lot of time, and if they look for it a little bit, they don't know when they will find it. But they can't just go to this place and go back, they need to find what they need, at least something that can get them out of this dark space.

The three of them yelled like crazy people, but it was useless, nothing paid attention to them, and there was no wind here, only that they were messy in this windless environment. They don't have much time, and they don't want to; Wasting too much time in this place, they are also quite worried about Wang Meng now.

Everything is to encourage them to speed up and keep moving forward, maybe there is the most critical place of this civilization not far from this place, but this probability is quite small, and they just have such beautiful fantasies.

They also regretted a little, they didn't take a closer look at what information was on the mural just now, maybe there was the location of this key place in civilization, but it was useless to say anything now. It was impossible for them to go back, the passage just now was just a part of the space, and after they arrived at this place, the passage mouth disappeared completely.

They have no way out, they can only look at the ruins and think about things, they are thinking that in this way they can quickly find what they need, it is better to have a high-level translator, or they are looking for some important documents and they don't know if it is what they need. The three of them don't know the words of this planet.

Finding a technology they need is like looking for a needle in a haystack, they are not familiar with this place itself, not to mention that there are only three of them, even if there are three hundred people, there is no place to find it, and this is still not counting the existence of classified facilities and the like.

"What should I do?" This has become a very critical problem for them, the three of them have no way to carry out it, even if they are giving them 10,000 times the number of people, it is not enough, for a while, they are a little unsure of what is good. This is a very serious problem.

"If we don't take out those words again, maybe some miracle will happen!" Qin Ming also has no good way, he can only remind Liu Xuan to try the lawyer's unhappy method again, this is the only way they can think of and can do it at present. Liu Xuan has no objection to this.

Turn on the projection function of the bracelet, project those words as large as possible onto the ruins of a place, and then wait quietly. Unlike usual, there was no direct reaction this time, and as time passed minute by minute, they were inevitably a little anxious in their hearts.

"So you came to our territory." Just when the three of them thought that nothing would happen, a voice suddenly appeared beside them, which made them retreat in fear.

See for yourself

Behind me, I don't know when. An old man appeared, and the voice just now was said by this old man, and a person suddenly appeared in this place, which could not make them panic!

"Welcome, my guest, but you have not been here for a long time, and according to the treaty of the time, you should have come to this place hundreds of years ago. Although it will not change the final result. Looking at the three people, the old man said faintly. It's just the content between the words, and they don't understand it.

When the identity of the old man was not determined, the three of them also seemed very cautious, looking at the old man with a nervous face, in case there was not much left, they would retreat quickly.
