I searched for more than a dozen similar prismatic crystals before and after, and I am afraid that none of them were as amazing as the ruins in front of me. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Half an hour later, when Lu Yuan stood on the sand dunes and looked down, more than ten kilometers away, on the desert Gobi, a building that was nearly half buried by sand and dust, and the exposed part alone was nearly 100 meters high and more than several thousand meters long, appeared in front of him.

The surface area of this planet is about the same as that of the earth, and Lu Yuan only searched and found the strong reflection of prismatic crystals, but he did not expect that there would be such a distinctive artificial building on this planet.

“…… It seems that there really is an extraterrestrial civilization. ”

Lu Yuan's expression was solemn, what does the existence of extraterrestrial civilization mean? It shows that the unknown organisms on Mars and on Earth are likely to have been on Earth hundreds or tens of millions of years ago, so what was the purpose of their original visit to Earth? What happened to the earth that he was sealed in the earth and in the belly of the mountain?

There are too many questions to know, unless he really takes the time machine and spends countless hours to investigate the truth in the past years, otherwise these truths may be buried under the long river of time.

But perhaps...... Here he can find something.

Lu Yuan took a step forward and instantly appeared more than ten kilometers away.

"Smack."

Landing on the dry sand, Lu Yuan raised his head slightly, and after a closer look, he found that this long-abandoned building was actually made of metal shells, I don't know if it was because of the special alloy, or because there was too little moisture here, these metal shells were not rusty except for being contaminated with a lot of sand and dust.

It was a huge hole in front of him, about ten meters in diameter, and under the dim sunlight, it was pitch black inside, and something was waiting for him.

Lu Yuan's eyes quickly turned to a solid inky black, and in just a moment, he frowned, and his eyes turned normal again.

Without hesitation, he walked forward, the dark environment did not affect him much, but the complex structure, beams, and dilapidated cables inside the building made Lu Yuan realize that the building in front of him was at least made by a civilization no less than that of the earth in the 21st century, and the volume of this building alone required the metal to be used was no less than a dozen aircraft carriers Ford.

How can this be created by backward civilizations?

"It shouldn't have been abandoned for too long......"

Lu Yuan glanced left and right, and estimated in his heart that the abandonment of this building would not exceed fifteen years, and the reason why he said this was not only due to the new and old appearance of the building, but also ......

"Bang Bang Bang ......"

Suddenly, there was a huge movement of metal knocking, which seemed to be harsh in this silent environment, as if Lu Yuan was not given much time to react, and two red lights flashed in the darkness, like a demon peeping in the dark crawled out of hell.

For normal human beings, it is almost impossible to see anything clearly in an environment without lights, but unfortunately Lu Yuan has no effect on this at this time, and the pupils of his eyes are dilated for a while, and he can see the faint light in full view, which is enough to clearly see what he is peeping at in the dark.

"Huh?"

When he stood outside, Lu Yuan noticed that there was an abnormal heat source signal inside the building, but he didn't know what it was, and when these heat source signals came out at this moment, he was surprised to see that three steel spiders with hideous appearances, like a hundred times magnified, quickly crawled over with sharp and slender metal feet, and surrounded him in the middle.

Nearly four meters high, each metal is more than five meters long, especially the front pair of steel chelicera, side by side sharp serrations neatly and neatly, just looking at it can not help but make people shudder, not to mention the four pitch-black barrels exposed in front of the chest plate.

This is not a natural creature, it is simply artificial...... Weapons.

This shape made Lu Yuan can't help but be curious, could it be that there are spider-like arthropods on extraterrestrial planets?

No, maybe it's not an imitation of a spider, but such a multi-legged arthropod structure that can be well stabilized and balanced, and under the optimized program algorithm, it shows better flexibility in complex terrain.

It's the same with the barrel.

In the history of the development of weapons, when entering the stage of thermal weapons, whether it is a gunpowder weapon or a kinetic electromagnetic weapon, a barrel that can give accurate trajectory is an inevitable technology tree.

However, this flexible mechanical spider cannot be reached with the current technology of the earth.

Just as Lu Yuan was thinking about it, the three mechanical steel spiders that surrounded him suddenly made a sharp sound and reached his ears.

"Hey, that's ...... High-frequency sound? ”

Most of the normal sounds used by humans to communicate are between 200 Hz and 8,000 Hz, and as humans get older, it becomes more difficult to distinguish high-frequency sounds above 8,000 Hz.

This kind of high-frequency sound that suddenly came out from the three mechanical steel spiders was almost inaudible to normal human ears, but it was sharp to the point of piercing in Lu Yuan's ears, and he immediately keenly noticed that there was a sentence break and logic similar to human language in this high-frequency sound.

Human language is clearly distinguished from animal language, that is, abstract thinking and pronunciation, and there are very clear characteristics in the syllables, words, phrases, and sentences produced by the sound, which is incomparable to the animal voice.

And the high-frequency sounds sent by these mechanical spiders were not without any regular noise, which made Lu Yuan realize for the first time that the other party might be having a conversation with him, or trying to communicate?

However, when neither side understands the rules of the other's language, this kind of communication will undoubtedly fail.

However, before Lu Yuan could think further, this piercing high-frequency sound suddenly dropped, and it only dropped to about 2,000 hertz after a while, which was already within the range of sounds that humans could normally hear and communicate.

“minkdiedieyk……”

Of course, I still don't understand.

Lu Yuan shook his head and gestured with his hand that he didn't understand. Just made such an action, he laughed dumbly, and the action of shaking his head on the earth may express different meanings among different peoples, let alone on an extraterrestrial planet?

But then again, should he be said to be lucky to find an extraterrestrial life that can move so quickly, or is it his bad luck?

Such an exchange does not seem to make any sense.

I don't know if these three mechanical steel spiders were also aware of this problem, and soon, they stopped making insignificant sounds, but they didn't leave there, and still surrounded Lu Yuan in the center.

This is troublesome, since the other party has made a sound, it means that the other party has not evolved to the level of communicating with brain waves, and still needs sound as an aid to communication, but the problem is that in the absence of language and text comparison, it is almost an impossible task to understand what the other party means.

In particular, extraterrestrial life has different organs of pronunciation than humans, which makes this even more problematic.

Although human beings say that the language of various ethnic groups is not comprehensible, because of the same articulatory organs, there will be similar single consonants in the sound, but if even the articulatory organs are different, then the sound will be directly different, and the north and south will be different.

I can't communicate, and it doesn't seem to make much sense to stay here.

And the other party doesn't seem to be friendly.

Lu Yuan's heart moved, and when he turned his head to look, he saw more than a dozen people...... Should it be human?

It seems that this cannot be described by human beings.

No one has the appearance of skin similar to snake scales, no one has four pairs of eyes on their head, no normal nose and other respiratory organs, no hair, and two pairs of wings on their back, I don't know if they can be used for flight. However, the dense tentacle-like organs that grow on the chest seem to be very flexible, floating around with their walking steps.

By the way, they rely on a few pairs of arthropods to walk, and they can quickly climb when they step on the ground, and from the time Lu Yuan saw them coming, the speed was about the level of a normal person's trot.

Is this extraterrestrial life?
