Runic Galaxy Realm

"So, what exactly is this Runic Realm?" Qin Feng asked.

"How should I put this... The realms we know so far are usually formed from an immortal's core billions of years after their deaths. However, couldn't there be a more powerful realm that originated from something else?" 

"From the information that we have grasped, the lowest realms are entities like territories or walls, which could be constructed by elects or spatial beasts alone." 

"Then, an intermediate realm refers to those housing a single planet or large continent that supports life within it. These are the ones formed after the deaths of Immortals."

"Above that are superior realms, where humans have yet to find a way to detect its boundaries. It encompasses numerous planets or several continents. Some could even exist in the form of multiple overlapping dimensions."
