Although the Extreme Yin Lake was located beside the Frozen Cloud Ethereal Sect and primarily visited by its disciples, it was classified as a natural training ground rather than exclusive sect property. As such, outsiders were allowed to enter freely.
However, despite this openness, the lake's unforgiving cold served as a natural barrier. The chilling Yin energy was so intense that only those who had cultivated the Frozen Cloud Ethereal Sect's unique techniques could withstand it for extended periods. For anyone else, this training ground was a perilous area.
Because of this, while technically open to all, in practice, the Extreme Yin Lake remained a place almost exclusively occupied by the Frozen Cloud Ethereal Sect's disciples, and even then, only their most talented and experienced disciples would dare to train there.
