When Petrux left, Mrs. Larry's mood was extremely mixed and conflicted. Of course she hoped that the red-bearded man would come back to save her, but she didn't want others to be put in danger because of her.

Seeing that Petru ran over the altar and was not attacked by the savages, Lady Larry breathed a sigh of relief. She sat down, her back against the cold rock. The giant moon in the sky didn't put much pressure on her, and nothing could be worse than what happened in the past.

She took Petru's words to heart and kept reinforcing her subconscious thoughts - no matter what happened, never leave. In fact, there is no need for Petru to say, she will also stick to this idea, because if she stays here, the worst result is death.

She looked at the moon and began to wonder how this phenomenon came to be. Is it the Moon that is out of orbit and crashing into the Earth?

If that happens, the whole world is not immune, what will happen to people elsewhere?

Is it like a wild man on the altar who prostrates on the ground and sings the doomsday prayer? Religious would, she thought.

Were you so frightened by this shocking sight that you can't think about it, so you can only stare up at the sky, waiting for disaster to come? That's about the case for ordinary people, she thought.

Is it wise and decisive to get on a plane and flee to the plateau or the other side of the world at the first time to get the slightest chance of survival? Rich people and politicians will, she thought.

Is it to prepare emergency plans, organize manpower, maintain order, make a final effort and die throes? True leaders and human elites would do it, she thought.

Is it to think about how to keep the seeds of human civilization in the safest place in a very short time, before the destruction of the earth, so that she has a chance to continue? Her friends, those scientists would do, she thought.

Is it because of dying, to burst out the ugliest side of human nature, to start burning, killing, looting, and doing all kinds of evil? Should...... No one would do that, she thought with less certainty.

She wondered how she could have such thoughts, so many thoughts, and find it interesting to think like this.

If this time it wasn't a disaster, if she could go back alive, maybe she could write these thoughts into a book, she thought.

……

The moon was still getting bigger, and there was a rumbling sound in the distance. She knew that it was a gravitational tidal tide that turned into a tsunami, and was it really doomed?

However, the next scene made her reject this idea. She saw the large rock in front of her slowly float up. The stone she was leaning against was also moving, and then it brushed her back and floated up.

One by one, the stones floated up and into the air. But her person was still sitting on the ground, and everything was normal except for some dizziness caused by the upsurge of blood.

Although Mrs. Larry is not a physicist, her field of study has been in the field of humanities and archaeology, but she still has basic knowledge of physics. No matter how close the moon is, it will not suck the stones from the ground into the air. Its gravitational pull only makes the tides a little larger, and as the Moon gets closer, the Moon orbits the Earth faster, perhaps once in a few hours, and then the continents will be submerged by the sea.

But now, the moon has been overhead for so long that it doesn't seem to be far away, and it's not like it's spinning around the Earth, or rather, it's not like it's seen on Earth, it's more like it's seen on the Moon's geosynchronous orbit space station.

And those rocks floating up must not be the effect of the moon's gravity. If the gravitational pull was strong enough to make the stone float, then she should float too, but she was still sitting on the ground.

There are more and more floating stones, densely floating in the air, like meteorites in the Kuiper Belt.

The stone floats to a certain height and does not move, as if it has found its own place. The larger the stone floats lower, the smaller the one floats higher, and the higher it goes, the fewer the stone blocks, and slowly forms a point at the top.

Mrs. Larry looked up and saw that it looked like a pyramid floating in space. She remembered the shape of the altar and finally understood that it was a pyramid that had been half built and that the stone blocks that were now floating in the air were the other half of it.

It's as if we are doing a geometry problem, drawing a trapezoid on paper, and then drawing auxiliary lines upwards along the hypotenuse of the trapezoid, and the two dotted lines intersect and become a regular triangle together with the original trapezoid. Of course, this is not a plane geometry problem, but a solid geometry, so what you see in the sky now is not a regular triangle, but a regular quadrangular pyramid, a pyramid made of dotted lines.

However, there are still rocks floating upwards, this time on the contrary, the large ones keep going up, and the small ones float slowly, stopping at a low altitude. There were already a lot of floating stones in the air, but these rising stones did not collide with them, and they floated to their places in peace along their respective trajectories.

There was already a pyramid in the shape, but now it is messed up with more stones. Mrs. Larry didn't understand for a moment, thinking that she was thinking too much, but it was only out of professional sensitivity that she would see the stone as a pyramid.

The moonlight reflected a strange light on the stone, forming a halo between the gaps in the stone. She shifted her gaze from the stone to the glow between the crevices, as if she were looking at the light from a skylight

At this time, it became clear to her that this was not one pyramid, but two pyramids—two pyramids stacked on top of each other.

The stones that float up form an inverted pyramid, which stands opposite the original pyramid and inserts into each other. Its base is at the spire of another tower, and its spire is at the center of the base of the other tower, where Lady Larry now stands.

Her feet stood at the center of the altar. Her body is the spire of the inverted pyramid.

Mrs. Larry didn't know if she was in a dream, but even if it was, it was a majestic dream—there was a huge moon in the sky, filling the sky, and above her head, two opposing pyramids stacked with meteorites.

The moonlight shines through the stone gaps and falls on the ground, creating a pattern of light and dark. The patterns are peculiar, like some strange symbols.

Mrs. Larry remembered that the savage patriarch's scepter, as well as their clay pots, had similar symbols carved into them. She judged it to be an ancient text.

She read it line by line, and memorized it all in her head. As the best archaeologist and linguist in the world, this is not a difficult task. The hard part is how to decipher these words.

After looking at all the specks on the ground, she unconsciously looked away to see the foot that she had covered—the location of the apex of the inverted pyramid—and the center of the base of the other pyramid.

She saw some lines on the ground, as if they were carved with some pattern. She crouched down to look closely, and the first thing she saw was a geometric symbol:

These are two regular triangles, the vertices are connected to the vertices, and a vertical line passes through the vertices and connects to the center point of the two triangles.

It was a familiar symbol she had ever seen. That's why she's aboard the research ship Discovery and join Robbins and them to investigate an ancient and mysterious ruin.

She saw some lines on the ground next to the symbols, not as straight as the symbols, but with some twists extending outward. She lay down and dusted the earth from the ground with her hands, recognizing that it was a mural carved in stone.

She guessed it was an ancient totem.

In the painting, it is a tall tree standing on the top of the sky, with the shape of a mountain range carved on the side of the root, a floating cloud carved in the middle of the trunk, and a circle on the canopy, I don't know if it is too bright or the moon.

On the highest branch, there is also a bird. 8)
