The hot air in the enclosed space is oppressed horribly.

time lapse.

Leiluo covered every corner of this space with spiritual strength several times in a row. His eyes kept scanning, but he still got nothing.

After all.

He took a deep breath and said calmly, "yes, I'm from the grand Academy of natural sciences, the place of the star screen in the surface world. I'm called [solar power] leilo. Then, who is your excellency?"

The Canary painted skin devil also looked around for a long time and found nothing.

"Me? Cough, you can call me an observer."

Observer?

Leiluo looked sideways at the canary. The Canary shook his head slowly. It was obvious that he had not heard of the name of this dark creature, which was not similar to the existence of Jiuyou.

After a slight cough, the observer continued, "so, dear surface world guest, what's your purpose here?"

"For the continuation of the civilization of anthropologists, I come here to obtain the knowledge here, the knowledge about the power of time and space, and avoid repeating the mistakes of countless civilizations annihilating in history."

Leiluo didn't hide anything and responded directly.

"Sure enough, cough,"

Faint voice, a sigh after a short cough.

"I have been assigned here to guard the rebels in this dark area for more than 1200 years. During this period, I have never stepped out of this vast valley. I have been with these rebels all day and tried my best to stop the spread of these substantia nigra. In the long boring time, I have been passionate and abandoned until a strong man who escaped from the surface world a hundred years ago He told me the news of the night place of the Crusade and the story I had never heard before, which brought me back to life and arranged the level of civilization. "

The so-called substantia nigra layer is the crack medium of the wall shadow devil.

Huh?

The arrangement of civilization level?

Ralo's face grew solemn.

Since the other party can say such words, it means that the other party is a first reformer who has changed the history of civilization. The academic circle has proposed the arrangement of civilization hierarchy for only more than 20 years.

In other words.

The other party is probably the underground world itself, but lacks the resistance environment of the surface world. The ruling organization of the divine faith here is much more severe and powerful than the central Turkish holy see in Aurora.

"Needless to say, the concept of level 0 primitive civilization is the use of wheels, the concept of level 2 civilization is the use of flying floating devices, the concept of level 3 civilization is the use of high-energy anti gravity devices, and the concept of level 4 civilization is the preliminary application of curvature space-time. So... Distinguished guests from the surface world, what do you think of the human academic community in your mouth Hierarchical civilization? "

"Level 3.5."

Leiluo youyou Road: "The human world" is divided into two parts: the Holy See and academia. As early as hundreds of years ago, anthropologists have developed a large-scale anti gravity war platform. With the increasing maturity of anti gravity technology and energy technology, the war platform is becoming larger and larger, and its functions are becoming more and more complex, which is enough to rival the divine existence. In recent years, the exploration of space-time knowledge has been started The door to knowledge. "

"Is that so..."

Murmuring in a low voice? There seems to be some remorse.

Suddenly.

Leiluo said: "Your Excellency, this arrangement method of breaking through the limitation of time and space as the civilization level? I have heard similar conclusions from another human? And it seems that this method of civilization level screening is more objective? Because as far as I know, this is the way a civilization above level 6 judges the civilization level."

"A civilization above level 6?"

Another voice, filled with some incredible.

Because according to the judgment method of breaking through time and space as the level of civilization, the underground world is actually only level 2.5 civilization, and the status of dark creatures in the underground world is far lower than that of landmark world scholars.

Why? On the one hand, because the academic knowledge level promoted by scholars has exceeded that of dark creatures? On the other hand, the divine system of the underground world is much more rigorous than the Holy See? The dark creatures want to fight? We also need to accumulate a higher level of knowledge to complete qualitative change.

Leiluo naturally did not respond to this six level civilization.

He said slowly: "However, in the human academic circles, I have also published my own cognitive system on the judgment of civilization level? That is to judge civilization level by mastering and using the rules. There is no need to say more about the first level primitive civilization. The second level is temple civilization, the third level is divine civilization, the fourth level is cataclysmic civilization, and the fifth level is lighthouse civilization. Civilization level is divided in this way If so, human academia has been preliminarily promoted to level 4 civilization. "

"So, what about the super body man?"

The observer's words made raylo squint slightly.

"Level 6... Primary star civilization!"

Leiluo's words not only silenced the hidden observer, but also shocked the canary.

It was not until a long time later that the observer's voice came again.

"It seems that the progress of knowledge exploration in your human academic circles has far exceeded the dark world of the underground world. I have contacted several senior elders in the three dark valleys of the underground world, but I have almost never heard similar words. Communicating with you is better than my hard work here for a hundred years. So... Is the civilization above level 6 mentioned by you also a super body?"

"No."

"Huh?"

Observing the stagnation of breathing, he couldn't wait to say, "what civilization is that? Where are they?"

Leiluo said, "Dear observation, I came here for academic exchange on curvature space-time knowledge, but you never showed up from beginning to end. Do you despise my long-distance guest too much?"

Uh?

Hehe hehe.

After the bitter laughter, he observed and said slowly, "it's not that I don't want to appear to see you, but that my form at the moment can't return to the real world, so naturally I can't see you. As for you, come to me..."

It didn't say anything later, and it seemed to think it was not realistic.

"So, it seems that you are talking to me in the curvature space at the moment, and this space-time technology has surpassed the exploration of human academia."

"You..."

The observer hears the speech.

"You human academia, have been able to maintain space-time cracks?"

"That's right."

Leiluo Road: "However, at this stage, we can only maintain a space-time crack with a diameter of 0.001 cm, and we haven't mastered the technology to embed it into reality. Naturally, we can't talk about communication, let alone the stable transmission technology with the help of curvature space and the development of sub space technology. Therefore, I'm here to obtain the relevant knowledge and technology that the underground world may master."

Stable transmission technology needless to say.

Sub space development technology, which is similar to the technology of space box, is far from being as simple as the space box, but is similar to the space-time technology of the air attic of the ancient holy object of Aurora.

Leiluo suspected that such an expanded sub space was hidden in the captured super human metal giant coffin base!

The most intuitive realization form of this sub space is that the internal space area is larger than the external space area, which is caused by the sub space changing the real world representation of space.

"It's a pity that you're a little late. The sleeper who mastered the crack solidification technology has died in that war. It is said that he has been able to solidify about 10cm cracks and conduct short-range shallow space-time shuttle. The space-time technology I mastered is to expand sub space technology and expand space area... Only 5cm."
