Millions of years of relics, according to common sense, may not be preserved to the present day.

Ordinary building materials, whether masonry or reinforced concrete, naturally cannot have a lifespan of millions of years.

Not to mention millions of years, I'm afraid that just the passage of 10,000 years can make those buildings no longer leave any traces.

However, in this world of extraordinary powers, many things cannot be seen with ordinary eyes.

The reason why this relic faced by Ye Zan and others can be preserved for millions of years is precisely because the building materials used contain the so-called "extraordinary power".

Of course, even extraordinary building materials can't keep this place as new for millions of years.

It can only be said that due to the difference in building materials, the buildings in the ruins were not weathered and destroyed so quickly, but they were still in ruins.

Ye Zan and the others came out of the war fortress and landed in the ruins of the ground.

"It seems that the Outer Demons must have excavated this relic a long time ago. After Ye Zan fell to the ground, he turned his head and introduced to the people around him.

Through the detector, Ye Zan can clearly see that on this million-year-old ruin, there are obvious traces of excavation and cleaning that belong to some more recent eras.

It's like visiting a tomb that was excavated decades ago and has been proven to belong to more than 1,000 years ago.

For today's people, the tombs of more than a thousand years ago are history, and the archaeological traces of decades ago are also history, but there is certainly a very clear difference between the two.

After listening to Ye Zan's words, Casaro and the others immediately understood the meaning, and then said: "So, before the Outer Heaven Demon came here, this civilization has been extinct for an unknown amount of time?"

"Well, at least here, that's how it should be. Ye Zan nodded, raised his hand to the side, and took a piece of something similar to masonry into his palm.

This piece of masonry, of course, is not so peculiar, at least in this ruin, it is simply everywhere.

Of course, compared with ordinary masonry, this masonry is indeed quite special.

After all, the main credit for the fact that this ruin has been preserved to the present day is probably due to such masonry.

"This thing seems to contain a trace of the power of the law, which is probably the reason why it can be preserved for so long. Casaro and the others were doing the same thing as Ye Zan and discovering this unusual feature from the building materials they picked up casually.

"Well, this power seems to have something to do with the laws of time, making time slow down many times in it. When Ye Zan said this, a faint light suddenly flashed in his hand, and the piece of masonry instantly turned into gravel.

In Ye Zan's hands, two bone claws of unknown origin were fused, one of which contained the law of time.

It's just that with Ye Zan's mastery of the law of time, as well as the remaining power of the bone claw, he can't really exert the power of the law of time.

At this time, the piece of masonry in Ye Zan's hand, it was precisely because the bone claw absorbed the power of the law in it that it instantly weathered into a pile of gravel as if it had been accelerated.

"Let's take a look inside! Although this place must have been looted by the Outer Demons, there should still be some residual information. Ye Zan threw the gravel in his hand to the ground and strode towards an area of the city's ruins.

It wasn't the center of the city's ruins that Ye Zan was going to go over, but not far from the place where they landed.

If there was really anything important, it was in the center of the ruins of this city, and Ye Zan would have led people directly to land there.

After all, this is not a closed space, and there is no question of where you have to get in.

Of course, strictly speaking, the landing place that Ye Zan and the others chose was already close to the central area, at least not in the outermost place.

The place that Ye Zan said was left by the demons outside the sky, and it was a trace of the investigation of this ruin.

There was a temple-like building there, and of course the building itself had long since collapsed, but the ruins revealed something that might have something to do with the faith.

And for Ye Zan and his party, what really matters is that in the middle of the ruined wall, there is a passage that has been opened and extends underground.

"Naturally, there's not much here, but there are some murals to look at. Ye Zan led the group down the passage and came to a space like a bomb shelter.

This underground space is not the kind of spacious dungeon style, but more like the kind of anti-aircraft and anti-nuclear fortifications in the world of science and technology. In other words, the underground space is not small overall, but it is basically divided into relatively small "rooms", but most of them are not separated by doors.

Probably, this is one of the reasons why this underground space has been well preserved to this day.

If it were replaced by that kind of dungeon-like structure with a very spacious space, I am afraid that this place would have collapsed many thousand years ago.

The murals that Ye Zan said are the "corridors" in this underground space, and it can even be said that all the "walls" are not blank.

In addition, these murals are much more elaborate than those of the more "coarse" traditional murals.

Murals, or the habit of painting murals, have probably been handed down from primitive societies.

In primitive societies, "people" did not have a very good information storage medium, so they would leave some information on the stone walls of the cave. Moreover, at the beginning, there was no clear text, and basically used graphics to express what they wanted to express, which was more like a "painting" in the eyes of later generations.

However, in this underground space, the murals are painted in great detail, and even the figures inside are clearly different.

Of course, this is also a matter of course.

It's a city relic!

Since this civilization has already formed such a city, the development of culture must have reached a certain level.

There are no text annotations on those murals, but Ye Zan and the others did not have difficulty understanding the content expressed in the murals from the beginning of entering the underground space.

"These murals are probably just a simple historical description. In fact, the meaning expressed in many murals is almost the same, it is that this civilization encountered some disaster, and then a savior appeared to solve the disaster. The Savior became the supreme ruler, who was famous in his early years and despised in his old age, and then there was another catastrophe and a new Messiah took his place......"

Ye Zan and the others looked at the murals on both sides of the wall, while "guessing" what was expressed in those murals. As I have already said, their "speculation" can be determined to be inseparably compared to the real situation.

"The Outer Heaven Demon moved really cleanly, and sure enough, nothing of value was left. ”

While inspecting the murals, Ye Zan and the others did not miss to explore and search for other aspects here.

However, unfortunately, as Ye Zan saw with the probe, there was indeed nothing of value in this underground space.

Although the "rooms" are not completely empty, they are only some broken tables and chairs and other furniture.

All in all, it's like an abandoned basement, like those empty offices where people go to them, and all that's left is discarded and unwanted.

"Still, these murals are very interesting, and it looks like they want to make gods in the end?"

Since there were not many other valuable things, Ye Zan and the others did not waste much time, and quickly browsed through all the murals.

And the message revealed at the end of those murals is what kind of experiment this civilization seems to be doing.

Although, the murals were not clear enough that all the experimental procedures were painted. However, judging from the comprehension ability of Ye Zan and others, it is not difficult to guess the general meaning.

The results of the experiment are also recorded on the mural, and it looks like the experiment was successful.

At the end of the mural, a huge monster appeared on an altar, which looked to be the octopus monster that had run out to attack Yezan in the first place.

However, what is certain is that the octopus monster that Ye Zan and they have seen is not the "god" on the altar in the mural.

"Although it looks similar, there are some differences between the two, maybe that octopus monster is just a descendant of this guy. ”

"It's not just the octopus monster, don't forget that there are many monsters in this inner world today, which are obviously not naturally generated. ”

Seeing the monster in the mural, and thinking of the octopus monster, as well as those strange-shaped monsters in this world, Ye Zan and the others seemed to know the reason for the destruction of this civilization.

In other words, they encountered some disaster, but they could not wait for the appearance of a savior, so they could only find a way to create their own gods. ”

As a result, their civilization was not saved, and perhaps even destroyed at the hands of these monsters. ”

Although, the mural does not depict what kind of disaster suffered by that civilization, let alone the reason for its final demise. However, from all this that they have seen now, Ye Zan and the others can know without guessing that that civilization has obviously been destroyed.

As for whether it was destroyed in a catastrophe, or at the hands of these monsters, or the result of the combination of the two. Without more information on Ye Zan's side, it is impossible to speculate further, and there is no need to dwell on this issue.

"Judging from the description in this fresco, as well as the situation of these ruins, this civilization still has some merit in the first place. Then, the gods they created would not be comparable to the octopus monster before. ”

The civilization in this inner world can keep the ruins for millions of years, which is enough to prove that the level of civilization is not low. After all, even the building materials contain the power of law, and it is by no means something that any low-level civilization can do.

Not to mention anything else, even on the side of the cultivation world, as long as it is not at the level of immortals, it is difficult to use the law to create things on such a large scale. You know, this ruin is a city ruin, which means that this civilization has used this ability for civilian purposes.

"Even that octopus monster can run outside through the space channel, so ...... It won't have anything to do with the giant natives outside!" After learning about the level of civilization in the inner world, Lin Mumu couldn't help but think of the giant natives outside.

Just like Lin Mumu said, although the octopus monster was able to open the spatial channel, the most important thing was because of the evil demons outside the sky, but its own strength also played a great role.

If the octopus monster itself doesn't have much strength, I'm afraid that even with the help of the demons outside the sky, it won't be able to do it to the same extent as before.

"If they can get out, I'm afraid that the disaster will not become a disaster, let alone take the risk of making gods. Ye Zan felt that the civilization of this inner world was probably a little crooked in the technology tree. Therefore, they were able to create a god like the octopus monster, but it did not mean that they had the strength of that god.

Of course, this "crooked" is relatively transcendent and civilized.

At this point, the civilization of the inner world may be a bit biased towards the technological world, at least some of the earth has probed into the technological world.

In fact, on the side of the technological world, there have also been some studies similar to god-making.

It's just that there is no supernatural power in the world of science and technology, and the research on god-making starts from the genetic aspect. Therefore, no matter how good the technological world is, it is impossible to create the existence of an octopus monster. Instead of building some gods, it is better to build starships and build those powerful weapons.

And here, due to the existence of supernatural powers, the civilization of this inner world is obviously successful.

It's a pity that the civilization of the inner world created this or this kind of god should not be under their control.

As for how to create gods, judging from the information on the murals alone, it is obviously impossible to obtain all the experimental materials.

If this underground space was an underground research institute, it should have been preserved with specific experimental materials.

However, Ye Zan and the others were too late, and the Outer Demons had almost emptied this place, leaving no information to study.

However, Ye Zan did not covet this god-making.

You know, not long ago, Ye Zan also "created" a real god with his own hands.

But on the other hand, Ye Zan is not completely uninterested in this, at least the things involving the power of the law here are still worth exploring.

It's a pity that the exploration of the Outer Demons to loot here is not only recently, but it was completed thousands of years ago.

Therefore, the group of extraterrestrial demons that Ye Zan eliminated did not have anything about the civilization of this inner world.

Those extraterrestrial demons were able to think of opening the spatial passage of the inner world only because someone knew such information.

It can be said that the last hole card of the demon outside the sky is essentially a practice of seeking medical treatment in a hurry.
