"Secret techniques not of the Nine Realms!"
Had anyone else heard these words, they might have been utterly confused, but Chu Ning's pupils shrank in response.
He remembered his time at Purple Mansion Academy, where he had learned from Di Yi about the outer world.
The Nine Realms, also known as the Ninefold Heavenly Realm and the Guiyi Realm, constituted a Minor World.
Above the Nine Realms was the Cangtian Realm, a Great Realm.
The secret technique mentioned by the Longevity Demon King, originating either from the Cangtian Realm or from another Minor World similar to the Nine Realms.
Having lived for so many years, the Longevity Demon King might well have had contact with the external world.
In this world, not only oneself is favored by the heavens; there are many others with unique opportunities who simply choose not to reveal them.
