The embryonic form of the Heavenly Court, this was where many Human Race Common Masters gathered the strength of the world, worked together to forge it, using an unknown amount of time and resources.
Although the main body of this embryonic form of the Heavenly Court was only a peak Spirit Realm Cave Heaven and had not truly evolved into a Small Thousand World, the foundation of this Spirit Realm Cave Heaven was far deeper than all other Spirit Realm Cave Heavens in this world.
Even the Longevity World that Pei Xuanjing had pioneered, if compared solely in terms of potential at this point, was still inferior to this embryonic form of the Heavenly Court created by the many Human Race Common Masters.
After all, when Pei Xuanjing first pioneered this Longevity World, it was also by chance and not intended, and at that time, he had not truly stepped into the peak levels, and many of his methods and Divine Abilities had not yet reached perfection.
