When Berlal said Arthur and Rishia would be there 'for a while', she meant an entire month.
The Valmone General Calendar's Date moved from the January 31st that it was on when Arthur entered Choth, to March 2nd before the godslayer finally finished his Realm advancement.
The energy level within the lake didn't appear to have dropped, but that was because the planet was releasing energy at the same rate Arthur and Rishia were absorbing it, leaving no visible change.
Rishia had completed her own absorption and breakthroughs a few days before Arthur, and she wasn't pleased about it.
In fact, when Arthur finally finished and opened his eyes, he found Rishia standing there, frowning at him in silence.
"Um…?"
He was understandably confused, but Rishia said nothing and looked away, unwilling to admit that her irritation came from the fact that Arthur had taken longer due to his larger reserves requiring more energy to fill.
