Celestial Plane, within Kurohana's plane.
A couple of days have passed since Kurohana's plans of enhancing her power to break through the Immortal Verdict Wielder level had started. At this moment, not much of a difference could be seen on the two people that resided within the confines of the pure white cube, which were Kurohana and Shirohana respectively. But if one peered in closely through the auras that they exuded, one would be surprised that their power had improved by quite a significant amount when compared to a few days ago.
Since Shirohana had most of the power that Kurohana had, she was tasked by Kurohana to master and control more of the Greater Law of Reincarnation. For the past couple of days, she had not moved from the corner of the white cube she positioned herself in, maintaining a calm and composed expression while she sat cross-legged, her body still attuning to the laws of the universe.
