The Star Realm Ball is a very special place.
Apart from being resource-rich, it also holds a very important strategic position.
That's because the Star Realm Ball is a barrier zone between the Cosmic Sky Region and the Star Zone, not only greatly preventing civilizations of the Sky Region from entering the Star Zone but also avoiding the entropy systems of the Sky Region from affecting the entropy systems of the Star Zone.
After all, the energy matter in the Sky Region is scarce, and its overall heat temperature is lower than that of the Star Zone. If it weren't for the existence and barrier of the Star Realm Ball, the heat energy of the Star Zone would have dissipated into the Sky Region long ago. This would exacerbate the entropy increase of the Star Zone entropy systems, thereby accelerating the extinction of the Star Zone and its internal civilizations.
