Inner Ring
Ryu tore through Raging Inferno Sect territory at an unprecedented speed. As a Fragmented Sky God, limited to such a speed, it would have taken him days to travel from one end of the Sect to another. However, as a Perfect Sky God, it only took him a couple of minutes to leave the outer ring and enter the inner ring.
This was a bit of a wakeup call for Ryu, not because he hadn't known the level of strength that acted as a gap between Sky God Realms, but instead because it reminded him that even if this was a large distance to him, that didn't mean it was a large distance to others. If he was not careful enough, getting trapped in the core of this Sect would be enough to end him.
But wasn't that part of the fun?
