After basking in pleasure for a while, Feng Xue gradually calmed herself, although the Heavenly Court, as a group of Kaidan, was obviously more prestigious and effective than Hundred Tales by more than just one level, the expansibility of it was not as good as Hundred Tales...even less convenient than Libra.
Because it was almost locked in this world.
The fundamental reason she was able to create the Kaidan of Heavenly Court in this world was due to the accumulation of two predecessors and their being thoroughly dead.
In another world, for Feng Xue to popularize the concept of Heavenly Court in a world without an Immortal Cultivation System, the required time was basically calculated in centuries, although, for the Longevity Species, this span of time wasn't too great, but since Feng Xue had been a Kaidan for less than ten years, transitioning into the mindset of the Longevity Species clearly needed quite some time.
