It has been said that if the Heavenly Court of the Divine Land World were considered a common interest group, then it is that large conglomerate formed by strong practitioners like Pei Xuanjing and various immortal sects.
The former Jade Emperor obtained the inheritance of the Human Race Common Master, then sold and transferred the thirty-six Spirit Realm Cave Heavens and seventy-two Secret Realm Blessed Lands to various forces and strong practitioners, allowing them to cultivate these as vessels for certifying Earth Immortals.
Later, after the War of Sealing Gods ended, when Pei Xuanjing and many Daoist Monarchs joined hands to pioneer the Heavenly world, they shattered the embryonic form of the Ancient Heavenly Court, transforming all the resources accumulated within the Cave Heavens and Blessed Lands into the foundation of the Heavenly Court, thus leading to the appearance of the Nine Heavens.
