"Uncle, we're also done," Kulla said, showing the gigantic mountain-sized palace that was floating in the air.
There were countless tubes stretching out from it that connected to the river flowing above their region, causing the water to flow through it before leading to a large lake on the ground.
Countless river streams flowed on the ground as well, but they were all artificial.
Plus, both the start and end of these streams came from the river in the sky. Also, the travel routes were the pipes that had openings in dedicated locations.
The river in the air had a mysterious current to it that all water streams branched out from it through artificial means would eventually return to the stream.
It was a mysterious trait as water would fully separate itself from the stream only when it rained or created some clouds while passing.
