Oftentimes, the simpler something was the fewer flaws it had. One of the simplest measures was to just construct a dimensional cage to imprison someone, one which was so stable and tough that there was no way to break through it.
However, simplicity carried its own stringent requirements. Ji Ning and the Autarchs were so overwhelmingly powerful and had such limitless reserves of energy that no mere dimensional cage could possibly withstand their assaults! The eight revolutions formation went about it in another way. It generated multiple worlds, each of which Ning was able to break through fairly quickly… but the worlds continued to be generated one after another!
"All of these worlds are extremely stable. Maintaining this sort of world can't be easy," Ning mused. "And there can't really be an endless amount of worlds!"
