Heavenly Realm.

The Rahu Demon Abyss is located in the extreme north of the Heavenly Realm. To reach its outskirts, one must traverse endless mountain ranges, boundless icy oceans, and desolate deserts spanning billions of miles, home to numerous fearsome beast tribes.

Before the catastrophe, the entire northern part of the Heavenly Realm was a lush and fertile land, rich in spiritual energy and treasures. Nearly a hundred Saint Sovereigns established their sects here, passing down their Dao Lineages. They held significant influence and power in the Heavenly Realm.

But now, this place has become the most barren and desolate region of the Heavenly Realm. Although the Rahu Demon Abyss is sealed, traces of demonic energy occasionally seep through space-time fissures, severely polluting the surrounding environment.
