No, why is it that only the arms of the statue are covered with moss? And the rest of the world is still bright?

Twilight found the spiral staircase from the middle of the pavilion near the mountain wall, similar to the one in the tower, except that the staircase here was not closed, it could be jumped down, and it didn't seem to be very solid, because Twilight had already seen a lot of damage, and he didn't know if it would collapse directly.

Feeling uneasy, Twilight Star descended the stone staircase, and although it had broken down in one or two places due to his arrival, it was still largely intact, at least it didn't seem to collapse easily anytime soon.

After descending the stone staircase, Twilight Star stepped on the moss-covered puddle, which made him feel very uncomfortable, the water was not high, only up to his calves, and the ground should have been carved with various patterns for decoration, but under the moss's cover, he could not see anything.

Summoning his long knife, he touched the water with his long body as he walked, to find out if there was a problem below, after all, the puddle here was covered with moss, and he couldn't see if the ground in front of him was safe, and if there was a pit that he didn't notice and fell, wouldn't it be a disaster?

Groping his way forward, he walked in front of this idol, and when he looked up, he really felt his own insignificance, standing in front of this idol, human beings, like an ant, were as incomprehensible.

Twilight used his long knife into the statue as a fulcrum, climbed up the statue's palm, and stood on the edge to observe it closely.

He noticed that the palm of the statue was not flat, but seemed to have many depressions on it, and to prove his suspicion, he stepped forward and scraped all the moss on it with a long knife, revealing the stone surface below.

It turns out that these places are carved out of stone, so it's no wonder that the rest of the statue is as bright as new in this humid environment, except for the moss on the arms.

In addition to this, Twilight also found riverbed-like dents in the palm of his hand, which appeared to be along the palm of the hand and down to the arms and shoulders.

Twilight didn't have to think much about it to guess that this must be a waterway used to open water, and the construction style of this ancient civilization was almost completely understood, so it was no wonder that water conservancy was used to build all kinds of mechanisms.

However, I don't know what happened to the kind of stone they used to build the altar, this statue seems so important, they only used ordinary stone to build it, otherwise it would never be covered with moss.

If it is because this statue is too large and the amount of stone is limited, you should know from the huge altar they built next to the reservoir that they are not short of this stone at all, they only need to use this to build the waterway, and the outside is made of gold. After all, the statue seemed so important to them.

After making sure that the waterway in his palms ended up leading to the large dry pool under the palms of both hands, Twilight climbed back onto the rooftop above, he was going to look for the relevant mechanisms on both sides, there must be something that could be put in, otherwise there would not be such a thing on the statue's arms.

Sure enough, Twilight spotted a two-person rotating switch on the table on the right near the statue's shoulder, and as he rotated the device, a square opening suddenly opened above the statue's shoulder, and a murmuring stream of water flowed out of it, and in an instant, it flowed from the shoulder to the palm of the water.

But the strange thing is that the water flow only gathers in the palm, and does not flow into the large pool under the palm, and the overflowing water flow also flows into the puddle along the edge of the palm, and the water level remains unchanged, indicating that the puddle below is also connected to the outside world and has a drainage or water injection device, otherwise it would not have been maintained here for so long.

Looking at the statue's other arm, which was still covered in moss, Twilight patted her head and quickly ran to the other side to find the corresponding device, opening the water outlet on this side.

With the opening of the mechanism, another stream of water flowed out, quickly covering the other arm of the statue, when the water gathered in the palm of the hand, and filled the small pool on the palm, as if some condition had been achieved, with a dull sound, the two palms of the statue lying flat on both knees seemed to open some mechanism, and the gurgling water was all poured into the pool below, quickly filling the pool.

There was another dull sound, and at the same time, a large amount of dust was constantly falling from the zenith, and occasionally small pieces of rubble were falling, and Twilight was terrified, feeling that it would collapse at any moment.

However, it turns out that the quality of the buildings built by those people is still acceptable, and although it is old, it is still working normally.

As the sound ended, a lantern-like device appeared above Twilightstar's head, this device contained a large diamond-shaped transparent crystal, and the device reflected the light out of nowhere, and with the refraction of the crystal balls on the rooftop, it made the place like a dream.

Twilight looked at this scene with a look of surprise, to be honest, the current situation was indeed a bit beyond his expectations, originally he thought that those people would only play with water conservancy facilities, but he didn't expect that now there would be an optical mechanism, but this is his appetite, because when it comes to light, this is what he is best at now.

The light from a device on the zenith was focused on the diamond-shaped crystal that had just appeared above Twilightstar's head, and then refracted through it onto the crystal balls on the rooftops on both sides, and then split into two rays of light again, one refracted to the top mirror, then from the mirror to the top of the statue's head, and the other to the statue's shoulder, where there was also a crystal ball.

After turning around, Twilight Star figured out what it meant, wasn't it just a total of five rays of light that shone on the five sides of the purple gem on the statue's forehead from five directions? It's so simple.

At this time, one of the five faces of the gem was facing downward, but this side was already illuminated by a ray of light, and the source of that light was one of the three beams divided by the diamond-shaped crystal on the middle roof, which refracted downwards on a crystal ball between the statue's hands, and then refracted upwards again, shining on the downward-facing section of the gem, and from the side, this ray of light looked like a colored V-shape.

After figuring out what needed to be done, Twilight easily aligned all the light, it was too simple for him, he could make his own light instead, and when all five beams focused on the purple gem on the statue's forehead from five directions, the gem emitted a strange and dazzling brilliance, combined with the refracted light around it, reflecting this sacred temple like a dream.

With another sound of mechanism, the stagnant water below gradually disappeared, and all of it was discharged, and the water openings on the shoulders on both sides of the statue were closed, and the ground below was completely exposed, which would be even more perfect if you could ignore the annoying moss.

In the middle of the hall, the floor suddenly opened, revealing a circular platform with a rotating mechanism similar to the one used to release the water.

Twilight had to walk down the stone staircase that looked like it was going to collapse at any moment, and as he slowly walked across the dry ground to the platform that had just appeared, he looked around the edge of the platform, knowing what it was all about.

This is simply an elevator, there is a gap on the edge of the platform, and it is not completely closed with the surroundings, which is also inevitable, because for those builders, this project is really a bit too precise, and the conditions are limited, only the edge can be treated like this, and the gap around can also prevent the platform from accidentally stuck.

Twilight checked it to make sure it wasn't dangerous, and began to spin the trap, and as it moved, the platform began to lower downwards with a click.

After a while, after about fifty meters of lowering, the platform landed on solid ground, stopped, and a brightly lit underground passage appeared in front of it.

However, something beyond Twilight's expectation was that after the platform was stabilized, it was tightly integrated with the surrounding rocky ground, as if it were one, and even the patterns on it were connected very smoothly without any flaws, which also made Twilight overturn the idea that it had just risen, these people's architectural ability was still commendable, and these ingenious buildings were built with such primitive and backward craftsmanship and methods.

Stepping off the platform, Twilight entered the bright hallway, which was as bright as day because of the sparkling gems, and was not darkened by the underground.

There are also murals carved on the walls of the corridors, which are completely different from those in the tower, and they seem to tell the story of the future, such as the construction of this hidden city in the heart of the mountain, and the subsequent parliamentary system, etc., because there is no absolute ruler, but they are no longer willing to be divided into many different tribes and disperse as they once did, so there is a parliamentary system, and a group of elders act as their decision-makers and leaders.

But what really caught Twilight's attention was one of the paintings, a stranded sea creature they had found on the beach, a creature that resembled a sea dragon that looked like it was alive at the time, but dying from being out of the water.

These people found it and brought it directly back to the city, divided and ate it, and felt that it was a gift from the gods, and estimated that the sea creature tasted good, but then they began to keep people dying of diseases, even those who did not eat the fish could not avoid it, and they were all infected.

The mural was also interrupted from here, and the back was all uncarved rough blanks, and Twilight estimated that they might be almost dead after carving the painting, and those who were still alive had no intention of continuing to carve it, but instead found a place to die.

"That's why this civilization is dying?" Twilight Star thought it was too bizarre, a piece of food from the sea had led to the demise of the civilization, and an unknown virus had killed them all, but it reminded him once again that the ocean here was very dangerous.

As for whether the sea creature carried the virus itself, or whether there was such a virus in the seawater, it was completely unknown, anyway, he would definitely not go to the sea now.

After skimming over a blank rock wall, Twilight continued to walk inward, the innermost part was a large hall, resplendent with many murals on the walls around the hall, but Twilight had no heart to look at it, his attention was now on the altar in the center of the hall.

Walking briskly up to the altar, the last pentagonal key was sitting on the stone platform without reservation, and because it was deep underground and because the outside passage was closed, there was only a small amount of dust on the key.
