The Extraterritorial Heavenly Demon originated from unknown sources, harboring a strong desire for destruction. The Immortal Realm has been in a standoff with these demons for several eras, yet the latter often remains in a disadvantaged position. Only their stronghold remains impregnable, otherwise, the Immortal Realm would have wiped them out completely long ago.
Nine thousand years ago, the Heavenly Ascension Ladder mysteriously disappeared. The eternal Elder speculated that it should be the work of the extraterritorial Heavenly Demons. Unable to defeat the Immortal realm, they opted to start from the Lower Realm, gradually eroding the Immortal Realm.
The void is like an ocean, and the world is like a fish in the sea, constantly moving. However, the Immortal Realm is such a gigantic fish, it's more like a colossal whale compared to ordinary fish, while Kyushu is like a dolphin.
