The dimension higher than the Void World was a theoretical world that only existed in the imaginations during the era Xin Huo was still active in.
"A world in an even higher dimension and greater power… But, that world is a dimension that is impossible, it wouldn't exist…" Xin Huo kept quiet for a while and he murmured again, "Impossible, it definitely is not The Impossible World, it surely isn't…"
"The Impossible World?" asked Zhong Yue, "What is so great about this world you speak of? Why is it called The Impossible World?"
Xin Huo left his question hanging there and suddenly, he ranted and whined as he jumped around, "What happened when I slumbered? Oh my heavens! Just how many interesting events have I missed! Why was I asleep for so long…."
The little flame ranted for a moment and suddenly, he hid back to the corner within the psyche ocean of Zhong Yue, sat there quietly and locked everything out.
