For a Nascent Soul True Monarch, Refining a Realm was not merely a simple matter of increasing one's combat strength.
Constructing one's own small world and evolving it into a Grotto Heaven was the watershed moment on the path to Divinity Transformation.
If a cultivator's highest goal was only the Nascent Soul Realm, then it didn't much matter whether their realm was perfect or had potential for growth.
At worst, they would be a bit weaker and at a disadvantage in combat.
But for those with lofty ambitions—prodigious talents hailed from the very beginning as having the potential for Divinity Transformation—the construction of their Nascent Soul Realm was paramount.
If the foundation was unstable, forcing the refinement of a Space Spiritual Object later on would be like mending the pen after the sheep have fled—it might not produce the best results.
A Grotto Heaven was hundreds, even thousands of times more complex and stable than a Nascent Soul Realm.
