The cage was perfect to counter Divine Demon's ability. The absence of energy inside the void and the white walls that isolated the two experts from the outside world served their purpose to limit one of the most flexible and miraculous laws in the entirety of the Immortal Lands.
Divine Demon found himself immersed inside the darkness illuminated by a familiar white radiance. A small cloud made of the azure energy absorbed before the activation of the trap floated around him, but everything else was either empty or belonged to a realm that he couldn't affect.
The white walls seemed to share the same fabric of the sky, and their power was also insanely high. They stood at the very peak, in the upper tier of the ninth rank. It was clear that Heaven and Earth didn't come up with that trap on the spot but had prepared it a long time ago. The old cultivator had even stated that, but his words couldn't compare with that breathtaking sight.
