Growing fast

Two days passed within the cold castle, completely imbued with Yin. During this time, all fifteen women advanced to the Foundation Establishment Realm at intervals of a few hours. However, they soon stagnated, still getting used to collecting Qi on their own and absorbing it. Alm and Bruno watched but weren't worried; in this extremely dense Qi environment, they could learn quickly, and in the future, they wouldn't face this issue anymore.

On the fifth day, Almin and Langrum broke through to the next level for the first time, but the speed quickly accelerated, raising them several times. On the tenth day, both reached the fifth level of the Foundation Establishment Realm.

"They've stabilized, and there won't be much more improvement. Time to start absorbing everything else," Bruno said casually.
