As Shen Mo's cultivation rose and his dealings with many true immortals became increasingly frequent, he learned quite a few secrets concerning the Immortal Realm!
The Immortal Realm's severance from the myriad heavens and worlds was cyclical, like the ebb and flow of tides. It could last as long as a million years or as briefly as several thousand, yet most true immortals had no idea what precisely caused these changes.
Guan Ling had once heard her master, the Nine Heavens Mystic Maiden, mention that this seemed connected to the remnants of the old era. Whenever the power these madmen had infiltrated into the Profound Yellow Universe reached its peak, such a situation would arise.
In other words...
The Immortal Feather Realm's decline, the destruction of the Immortal Feather Upper Sect, and the severance between the Immortal and mortal realms had all occurred during roughly the same period nine million years ago. Clearly, these three great events had not been mere coincidence, but were closely intertwined!
Based on this crucial point in time, Shen Mo determined that the time within the Evil Spirits was the five thousand two hundred and seventy-third year after that event.
More than five thousand years ago, when Daoist Lingyu saw that he could not ascend to the Immortal Realm, he could not help but be greatly alarmed!
By then, he had already guessed that the entire Immortal Feather Upper Sect, including its five true immortal patriarchs, had met with disaster.
The separation of the Immortal and mortal realms was merely a "barrier between Heaven and man" for beings below the True Immortal Realm. Immortals with profound cultivation could still manifest incarnations throughout the myriad worlds, and if they were willing to expend their immortal power, they could even cross the void and travel freely
