[Elder Sister was originally a True Monarch of the Profound Realm, descended upon the Mountain Sea Realm due to certain events, and used the Nirvana Secret Technique at the brink of death to be reborn and cultivate anew.
A thousand years have passed, since her rebirth, Sister Qi Xia has gradually cultivated to the late Nascent Soul Stage, but because of this realm's suppression, she could never break through to the Void Refining Stage. Furthermore, a force of the interface has been binding her, making it not only difficult to break through but also extremely arduous to ascend. She even foresees that if she doesn't leave soon, she would be completely trapped in the Mountain Sea Realm.
