On the way, Twilight was thinking about the beam and the crashed ships that had crashed before.

The large ship broke in two, the medium one split apart, and several parts fell on the planet, while the small one turned into a pile of debris, which seemed to explain the power of this beam, but there was one thing that Twilight couldn't figure out anyway.

"Since there were survivors on the medium-sized spaceship that crashed first, doesn't that mean that this beam has no radiation lethality, so why didn't there be any survivors on the large spaceship that crashed before? After all, if anyone survived, they would definitely call for help before me, and I used such a rudimentary communicator to contact the rescue spacecraft, so there was no reason why they couldn't reach it. ”

Twilight thought it was strange, the large ship had just been broken in two, there was no reason why there were no survivors, and if the beam could kill humans with its own radiation, then there was no reason why the medium-sized ship could have survivors.

Twilight shook her head, it seemed pointless to think so much, so let's look at it.

At this time, Twilight Star had already approached the tower, and at this distance, Twilight Star's previous sniper ranging experience could determine the height of the tower, about 170 meters, and the tower was straight up, built unconventionally, and there were many opposing and neat windows on the tower, which allowed the building to be fully lit during the day, so that the inside could be brightened during the day.

At the same time, Twilight Star also discovers a very peculiar place, that is, the tower has a total of four entrances, and the four entrances are neatly aligned in four directions, one of which is the direction of Twilight Star, the east, the mysterious reservoir.

Twilight felt even more curious about this discovery, and there was indeed an inexplicable connection between them, and with the mentality of finding out, Twilight Star stepped into the building.

Twilight kept looking around, this floor was a hall, and the top was very high, this tower was at least a tenth of a floor, and in the middle was a cylindrical spiral stone staircase leading to the upper floor, the entrance of the stone staircase was in the northwest direction, where it seemed to be the direction of the mountain peak that shot out the dark green beam before, there were too many coincidences in it, and it was impossible to believe that they were not related to Twilight.

Twilight didn't rush upstairs, but carefully looked around in the bottom hall, this floor was completely divided into four parts, in four directions, divided into four frescoes, the eastern fresco painted the altar, and a large number of the altar carved on the water waves, sure enough, all of this is closely related, Twilight Star thought so surely.

The southern mural seems to be painted with flames, the western one depicts a high mountain, and the northern one is a continuous mountain range.

The more he looked, the more confused he became, Twilight decided to go upstairs to take a look, but there was really nothing to see below.

Walking up the stairs from the northwest entrance, Twilight Star found that the walls next to these stairs also had murals, and what was even more amazing was that the windows on the staircase walls were completely in a straight line with those windows on the tower, and the outside light could shine on them, which also caused the staircase that was obviously inside the tower and still had walls around it to be so bright that there was no need for Twilight to use light magic to illuminate it.

The staircase, which should have been dark, sparkled in the faint sunlight, and the twilight star's subtle observation found that these rocks seemed to be filled with dense diamonds, and the size of the diamonds was only less than 0.2 mm, almost invisible to the naked eye, which also caused the spiral stone staircase that should have been narrow and closed here to shine brightly and dreamlike.

I couldn't help but sigh as Twilight thought that if I had the chance in the future, I would definitely have to make such a compelling building, which looked amazing.

After turning his attention to the mural again, Twilight started from the lowest mural and went all the way, the content of the mural carved here was relatively easy to understand, although Twilight couldn't read the square words engraved on it, but just looking at the content also made a general idea.

The general content is that a civilization on this island is the same as humans, since primitive times, it has been divided into various tribes scattered on this island, and they are constantly fighting and plundering each other, and at that time it seems that dinosaurs already existed, Twilight Star saw them on many murals, or some large dinosaurs appeared in the image of terrifying destroyers, or became the trophies of a brave man, and most of the other small dinosaurs were their food.

Judging from the frescoes, they had always used stone or wooden weapons, which made Twilight feel incredible, but when she thought about the stone platform on the altar that she couldn't damage with her D-class long knife, Twilight felt a little clear.

The murals along the way are basically the history of their conquests, the rise and fall of each tribe, all on these murals, until one day, a nearby tribe has a change, they seem to have found something on the northwest peak, it seems, it seems to be a square building, just like everything Twilight sees now, but there seem to be some regular lines on the building.

This reminded Twilight of the water bottle in the reservoir before, and the surface of the water bottle also had various lines, and it was the same dark green as the beam of light emitted from the peak, so that the water bottle was related to the buildings on that mountain.

Twilight continued to look up, and the natives seemed to have been given a sign in the building, which looked so big that it was the size of the man's torso in both hands, and it seemed to have some special purpose, and the natives worshipped it like a god.

Thus began another war, and the other tribes got the news and coveted the sign, and another chaotic war began, until at last, a king unified all the tribes, and he held up the sign in the midst of everyone's prostrations and support, and entered the mysterious building with the sign.

Seeing this, Twilight Star couldn't help but wonder a little, what was the use of that brand? It's worth fighting for, and what did that guy do in that building with a sign?

Twilight Star is surprised by the image on the mural, which is exactly the same as the one he had seen before, except that the ship on the mural has become larger.

The mural depicts a spaceship coming from the sky, then being pierced through the air by something like a spear of the gods, and then crashing in pieces, and the natives rushed at the wreckage that crashed on the island with their weapons, and actually caught some loot, which seems to be the original owner of the communicator that Twilight Star carried, the survivors who survived.

But judging from the content on the screen, their results are not very good, they are treated as invaders, they are demons, they are all burned to death, and the building that fired the beam of light is also considered to be a god, but they seem to have thought so before, otherwise they would not have played like that for such a brand.

Then it seems that the king died, and then the originally unified tribe was divided again, and everyone wanted to hold the brand from the gods, but no one could do so, and in the end, after a series of battles, it was still fruitless, and the brand had to be sealed.

The specific sealing process is probably to build such a high tower to worship Thor, and then lock the brand in a device at the top of the tower, let Thor, and give the four keys to open the seal to the other four gods to guard, and no one can get it until there is a king who can make everyone surrender in the future.

By the way, some of the things that Twilight drew from the previous murals, these aborigines believed that the building on the hill in the northwest was inhabited by the gods, and the gods had five servants, the god of thunder who lived in the sky, which was the strongest servant, and the four gods located in the east, west, north and south.

Looking at the altar built next to the reservoir, they thought that it was the abode of the god of water, so they built an altar there to worship the god of water, and it was also used to store the keys.

Twilight looked at the murals with some tears and laughter, although he didn't know if the gods believed in by the aborigines were real, but at least the so-called water god had already made Twilight feel very troubled, after all, he had also obtained one of the keys there, and he felt quite bad at the time.

The so-called water god does exist, which Twilight does not deny, after all, Twilight did perceive the mysterious existence in the reservoir at that time, and it feels quite terrifying, but as for whether it is a god or not, it can only be seen by the benevolent and the wise, for the human beings on the earth, Twilight's current physical fitness and magic can also be called a god, as long as Twilight's disguise is good enough, and does not allow others to have the opportunity to use some powerful technological weapons against themselves, then for mortals, he is a god.

After seeing these beautifully carved murals along the way, Twilight finally reached the top of the tower, but it was only then that he realized that the tower was more than 100 meters high and only had two floors in total, which really made him look forward to it in vain.
