As Fuxie had said, the entire seal of the Immortal Palace was a Taiji Hunyuan Array—a grand formation containing all elements of Yin, Yang, and the Five Phases—making it perfectly suited for An Jing’s cultivation.
This was not a matter of being favored by destiny, but rather a functional necessity. For a formation to be both powerful and enduring, it had to rely on pure Yin-Yang polarity, the Five Phases Hunyuan, or the Taiji Hunyuan. The Taiji Hunyuan was the most durable, capable of maintaining operation for the longest time. Consequently, the vast majority of ancient arrays that had survived to this day were of this type—a clear example of survivorship bias.
An Jing walked back into the Immortal Palace. With the Heavenly Demons’ influence purged, the frost had receded and all things were coming back to life. The array patterns within the palace flickered one after another, as hazy and magnificent as a flowing river of stars.
