Soulful Observations

Had Rui foreseen this particular outcome unfolding ahead of time, he wouldn't have done it in the first place.

Yet he didn't.

His expression grew grave even as wonder and awe sparkled in his eyes as he beheld a live breakthrough to the Sage Realm. The man's presence grew extraordinarily heavy as his mental activity ceased to register in Rui's Martial Mind.

Time slowed down to a crawl in his eyes as his deep curiosity for all matters related to Martial Art overtook his sense of self-preservation.

Rui studied the breakthrough carefully in multiple activities.

He studied the man's body with his senses, but he also studied him through his systems of thought. 

The VOID algorithm didn't read any difference.

Neither did the Tree of Life.

Yet, that alone told him much. 

The antithetical adaptively evolved environment for the species his Martial Body was hadn't changed.
