Within the many dimensions in the fifth kiln were three borders. They were like boundary lines that divided the fifth kiln into four regions.
These borders were formed by a ring of floating platforms, and each one of them was known as Spirit Trudging Platform.
At that moment, there were six platforms shining with a faint light. They were connected together, and could be seen from the distance. As for the other platforms, they were shrouded by a layer of fog, making it so people would be unable to see them clearly and tell what precisely was on them.
Six shining Spirit Trudging Platforms meant that there were six people who had stepped into the fifth kiln. If more people arrived, then more Spirit Trudging Platforms would be revealed from their indistinct state.
