When he was already alone, Rise finally realized that perhaps... That guy from Blue Guild happened to get lucky and stumbled upon the weakened flesh, which was so close to dying.
And the reason Blue Guild did not disclose anything was that there was nothing to be disclosed to begin with. After all, a lot would happen in two years, the time when the gate was cleared.
Anyway, Rise not being there personally could only deduce based on what he encountered and could not say he was right in his speculations.
The matter with the massive flesh was basically over, but the implications truly help Rise. Maybe, just maybe, he needed to brace himself to encounter the same anomalies in the future.
Rise gradually adapted to being part of the guild again, or more like the guild were finally accepting the reality that he was indeed part of the guild from now on.
Just like that, another week had passed. It was officially two weeks since he returned.
