Huge buildings must require a certain amount of technological strength to build, especially this kind of structure, which is several times larger than the Egyptian pyramids, even if it is impossible to fill it with human life. That's a good idea, but it's a premise that applies to humans, and if you switch to extraterrestrial creatures, who knows how big they will be?

Looking at the patterns on the stone wall, and then thinking of the passage more than ten meters wide and five or six meters high, Luo Xu thought for a moment, assuming that the size of these extraterrestrial creatures was not like humans, but much larger, then building this building would definitely not be as difficult as humans, and the technical means to be used would be invisibly reduced a lot. Ten tons of stones, human beings need dozens of people or hundreds of people to carry it, and even need to use machinery and other equipment to complete, if the size of extraterrestrial organisms is huge, then for them only one person can move, compared to the technical means and difficulty required is not a degree.

After recording all the patterns carved on the stone wall, Luo Xu walked to the stone wall on the right, and the searchlight light automatically weakened to avoid dazzling reflections, and there were indeed four patterns on the stone wall like the one on the left. Just the content of this pattern is worth debatable, the first pattern is on it, there is a centipede drawn, well, the strange thing is that this centipede's back also has dense feet on the lower arthropods, it is symmetrical up and down, and the back of the bottom is full of feet.

"Heh, you're really talented, centipede, you look like this, can't you turn over and continue to climb!"

Luo Xu became interested, such an interesting creature, he really wanted to catch one and raise it himself, if he put it together with the earth centipede, I don't know what would happen, just thinking about it must be very interesting.

The point of the "ahem......" question is not this, but what is the meaning of the painting? Just to draw a quirky creature on a single page? Maybe it's the domestic animals of these intelligent creatures?

After reading the first picture, Luo Xu's eyes turned to the second mural, the second picture is even more weird, to say that the first pattern Luo Xu can barely understand, the things on the second pattern, it is completely confusing. Seriously, it is a thing similar to a fish's head, with huge eyes on both sides of the flat head, and upper and lower jaws, but unlike fish, the mouth of this thing is too long, more than half of the fish's head, and it looks very strange at a glance, and what is even more peculiar is that behind the fish's head, instead of dorsal and caudal fins, it has a soft-limbed body like a snake, and there are feet underneath.

The first pattern can only be said to be weird, and after Luo Xu saw the second pattern, he not only lost interest, but also felt an "evil" aura from the mural, and couldn't help but subconsciously avoid his eyes.

"What am I afraid of, it's just a painting......"

Luo Xu shook his head amusedly, annoyed by his subconscious "fear", and stopped looking at the second painting carefully, and walked a few steps to the third mural.

"This thing...... Interesting. ”

The third picture depicts thousands of intertwined soft limbs, and the central part of the soft limbs reveals a "sparkling eye". The creatures depicted in this mural are obviously very skillful, and the patterns carved on the stone walls are not lifelike, but the "taste" is particularly highlighted, and people are attracted by the mural rather than roughness at a glance.

Luo Xu was a little speechless, this kind of depicted creature was no longer something he could understand, just like aliens couldn't understand the animals of the earth, he was also in the same situation. In this case, he did not think deeply about the meaning of these patterns and what creatures they represented, but directly recorded them and saved them as future research materials.

In the last picture, there are no strange creatures depicted, but the glowing round object that Luo Xu saw before, and a triangle contains the round object.

Luo Xu's mind moved, remembering the strange symbol of the triangle inscribed into a circle discovered by the gyrocopter before, he was still a little puzzled at the time, but now he understands that the meaning of that symbol is that this round object is preserved in this building. The root of everything comes from that mysterious round object, and all you need to find is to know all the truth.

He couldn't help but feel that he had found a clue to the matter, and he was now very interested, full of curiosity about that mysterious round object, what was it? What does it do? Where did it come from? Why was this pyramid built? There were too many questions for him to understand and explore.

After looking at the patterns on the stone walls on the left and right, Luo Xu finally came to the platform that was several meters high from the surroundings, on top of this platform, a stone slab similar to a coffin was placed upright, the stone slab was smooth and flat, without the slightest gap, and I don't know what it was used for.

Luo Xu immediately raised his head to check the situation of the stone wall, but this stone wall has no murals and no special symbols, it seems to be just a simple ordinary stone wall, Luo Xu checked it for a while and gave up, this stone wall is indeed no different. Then, only this stone slab placed on the platform was very eye-catching, and Luo Xu put his eyes back on the stone slab.

"What the hell is this thing for? It can't be used for sleeping, right? ”

"Uh......"

Luo Xu's metal armor-covered palm was placed on the stone slab, and a faint red light gradually emerged from the pitch-black stone slab, from left to right, dense and flashing red light special symbols like torches lit at night, and they were also very conspicuous under the light of the searchlight.

Luo Xu, who was in shock, instantly tensed his spirit to the extreme, and immediately took two steps back, his expression was heavy, his vigilance was kept at the highest, and he was ready to deal with any danger.

However, under his vigilant preparation, except for the symbol of red fire flashing on the slate, the expected dangerous situation did not appear, which made Luo Xu, who had been vigilant for a while, relax slightly, and then took two steps forward to observe the sudden change of the slate.

The pitch-black slab, which is about two meters long and forty centimeters wide, has been a pitch-black smooth vein, but now it has produced almost countless symbols. These symbols, which have their own special structure, are as if they are deeply imprinted on the stone slabs, and those red rays are emitted from the notches of the symbols, which set off the dark background, making it easy to identify all the symbols.

"Bob, are these symbols textual messages?"

"SIR, according to the image processing results, has a total of 3127 symbols, 127 symbols of the same symbol, 547 symbols of similar structure, 2453 symbols of different symbols, and there is a 90% probability of four text information with the same meaning and different structures."

"Four different textual messages?"

Luo Xu frowned, on a stone slab, why do you need to use four different text information to summarize and describe a meaning? Luo Xu quickly understood this question, "I see, the four text messages are used for people of four different races or different countries. ”

Luo Xu didn't ask Bob if he could decipher the meaning, in such a short period of time, there was no actual comparison reference, and it was undoubtedly a fantasy to decipher the four characters just based on a small amount of information on a stone tablet. But he couldn't decipher the meaning of the information on the slate, so he didn't know what to do next? Is there an impasse? Or do you want to go home?

Just when he was a little annoyed, the slate changed again, and the thousands of symbols that emitted red light slowly faded, and disappeared in less than a few seconds, returning to the original shape of the slate.

"Hey, why did it disappear?"

As soon as the words were spoken, the slate suddenly brightened, exuding a dazzling brilliance, and a three-dimensional virtual image suddenly floated from the slate, from the bottom to the top, when the lightning was shining and the stone fire, it had grown to four or five meters high, suddenly forming a huge three-dimensional image.

This change happened suddenly, Luo Xu couldn't react, and when he immediately took a few steps back, a three-dimensional image had already formed, directly facing him. Ordinary people may not know about this kind of real three-dimensional image, but how could Luo Xu not know that he was extremely familiar with these, and of course he immediately saw through that it was not a real creature in front of him, but a virtual three-dimensional image, and he was relieved.

But then he lifted up in one breath, and the extraterrestrial intelligent creature finally appeared, although it was only a three-dimensional image, but who knows where the extraterrestrial creature was standing and controlled, maybe it was not far from Luo Xu, how could this not make him start to get nervous.

This huge creature four or five meters tall has a rather peculiar appearance, thanks to the clear three-dimensional construction, all the circumstances of this unknown creature can be seen clearly, only to see that its head is very large, its face has a round bead, and it seems to be eyes, except that it does not have the nose and mouth structure that human common sense should have, and its face is flat and only the central eye remains.

And this creature has no hair, and the glowing head of Bai Ze is very similar to exposing the skull, which is bare and reminds Luo Xu of a motorcycle helmet. Underneath the skull, there is also a neck attached to the torso, but its hands are not two, but symmetrical from the shoulders to the sides of the abdomen, there are three pairs of six, and there are not even human fingers, but mucous membrane-like balls of flesh, God knows what they are used for.

The lower body of the unknown creature, according to the concept of human beings, should be legs, but Luo Xu felt a chill in his heart when he saw it, and his legs were not at all, instead they were hard arthropods like four arthropods, which were covered with cold serrations and barbs, and the four arthropods were stuck in the ground like spiders to support the huge body.

Luo Xu felt a lot of affection in his heart, this creature was so huge, if he wanted to support his body, the hardness of the four arthropods could be imagined, not to mention that when he saw the serrations and barbs, it made people feel scared. (There's one more shift today, and I'm desperate...... ）
