Located in the Infinite Celestial Realm, the Infinite Cave Heaven is one of the foremost Ancient Immortal Sects in the Middle Immortal Realm.
Their existence has been so long that even the disciples within the sect find it hard to pinpoint.
The name of the Sect has long become a symbol within the Immortal Realm, sung by countless immortals for generations.
Back then, one of the three entrances to the Enlightenment Immortal Tree was guarded by the Immortal Dao Alliance led by them.
Even if an Immortal Emperor from the Upper Immortal Realm descended here, they would be respectful and adhere to etiquette.
Because in the Upper Immortal Realm, another Infinite Cave Heaven has three Immortal Emperors stationed!
Currently, the Infinite Cave Heaven in the Middle Immortal Realm also has 15 Immortal Kings present.
And these 15 are all ancient Immortal Kings, having lived for billions, even tens of billions of years.
