Kyle went closer to the wall and touched it.
'That's pretty solid, but I can actually sense it with my Ether Sense. That means it's made of different materials.'
Kyle used his Ether Sense to analyze the wall, and he found some familiar Ether in it.
'There's a lot of Ether in there. Most of it is Metal Ether, but there is also Earth Ether. There is no Fire Ether or Wind Ether in there, but there are other kinds of Ether.'
'It's not that easy to sense since I don't have an Affinity for them, but I think that's Darkness Ether and Light Ether.'
Kyle narrowed his eyes and looked at his hand.
A moment later, a small black ball appeared in his hand.
Darkness Ether.
One had to remember that one could technically summon whatever Ether they wanted, even if they didn't have an Affinity for this kind of Ether.
It just took over ten times the Ether to conjure this kind of Elemental Ether. It also took far more focus, was slower, and the Ether was rather unstable.
Just as Kyle could conjure Darkness and Light Ether, eagles could walk on the ground. Yet, using Darkness and Light Ether to battle would be like asking an eagle to hunt without flying. It might work in some cases, but only against enemies that were far weaker than they were.
'Yep, that's Darkness Ether inside that wall,' Kyle thought as he compared his own Darkness Ether to the Darkness Ether inside the wall.
Then, he did the same thing with Light Ether and confirmed that the wall also had Light Ether inside of it.
'That should be it,' he thought. 'Four kinds of Ether are in that wall.'
'Metal Ether and Earth Ether. The stone above the Anti-Wind has these kinds of properties.'
'And as for Light and Darkness Ether…'
Kyle glanced to the west, towards the place where the Duchess of Twilight was.
'She has Darkness and Light Ether. I wonder, did she use the Metal-Earth Stone to create a new material by fusing it with her Darkness and Light Ether?'
'If so, she was the one who built the wall.'
'I mean, it would make sense. She said she's been here for over ten thousand years and that she is also the Overseer. If the world didn't create this wall by itself, it must have been her.'
Kyle touched the wall again and pushed on it.
He had a lot of experience when it came to analyzing materials, and he quickly managed to analyze the material to some degree.
'If I go all out, I think I could break through this thing,' Kyle thought. 'I just need to launch a bunch of attacks with all my strength, and I would be able to slowly dig a hole into it. Although that would be akin to using a spoon, or several spoons, to dig through a prison wall. It will take forever, and I have to go through a lot of spoons.'
'If I can do that, Emperor Winterfire can also do that. He could've made a hole in the wall to assault the Skysand Kingdom from behind. The fact that he didn't do that gives more credibility to my theory. The wall was made by the Duchess of Twilight, and she doesn't want anyone to get to the area behind it.'
'Wonder what's behind there.'
Kyle smirked.
'Well, there's a way to find out!'
The next moment, Kyle shot into the ground and rapidly descended.
He reached the Metal-Earth Stone rather quickly and kept going down.
'Just as expected, the wall also extends underground,' he thought as he looked at the black wall beside him.
Eventually, he reached the Anti-Wind.
'Let's see if the wall also extends into the stream of Anti-Wind,' he thought with a stream.
Kyle stepped-
"WHOA!" he shouted as his leg broke.
He hovered just a bit above the stream of Anti-Wind as he looked with shock at his leg and the stream.
'Bro,' he thought while his leg healed.
Then, he took a chunk off his hammer and dropped it into the stream.
Dink.
It bounced on the stream for a moment and moved a bit to the right.
When it landed again, it bounced once more and moved even further right.
A couple of bounces later, it gained enough speed to dig its own hole towards the right.
'There it goes,' Kyle thought, watching from a distance as the chunk of metal kept bouncing on the stream and speeding up.
Yet, a couple of seconds later, it eventually stopped bouncing and sank into the stream.
Kyle looked back at the stream.
'Bro, how fucking fast is this thing?' he thought as he looked at the stream.
In fact, the stream looked like a wall, but it wasn't a wall.
It just looked like a wall because the stream moved so insanely fast!
'Dude, this thing probably moves at speeds of over two kilometers per second! I can't get through that!'
If Kyle forced himself to enter the stream, the best-case scenario would be that he got thrown towards the west, which was currently to Kyle's right.
The worst-case scenario would be death.
There was no shot that he could fight against such a heavy and fast current.
'The current is much stronger here at the wall. Does that mean the Anti-Wind comes from the inaccessible area between the walls?'
'I thought it just went around the world, but apparently not.'
Kyle looked at the wall.
'Well, at least I know now that the Anti-Wind isn't just some random current going around the world but a directed force aimed towards the center of the world.'
'Speaking of, that's where the big landmass is, and the big landmass has the most Ether Essences.'
'This could be related.'
Kyle scratched the back of his head.
'Yeah, well, doesn't really matter. I don't need Ether Essences.'
'Since I'm going to be the Overseer anyway, I will get access to this part of the world eventually.'
'Anyway, I should actually start comprehending the Fragment of Wind Expansion. I got a bit sidetracked.'
