Sovereign's edict.
Regardless of how the sects and forces outside the Great Chen Dynasty perceive it, the Heavenly Sect of the North Mysterious Sacrifice Continent ultimately sees it as a kind of 'Heavenly Revelation' when the Emperor of the Great Chen Dynasty issues the most formal decree.
Even though Ye Po True Lord has little regard for Da Chen in her heart, she still, with the most formal etiquette, brought the decree back to the Bright Mirror Sect, placed it inside the grand hall of Bright Mirror Mountain, and waited for the return of the patriarch and others such as An Jing.
All the survivors within the Bright Mirror Sect witnessed the scene of the decree's return to the mountain.
Due to the Nirvana Tribulation, now within the Bright Mirror Sect, only a small portion of the young generation guarding the mountain still have their physical bodies; the great majority exist as souls, relying on the Spirit Land of the Great Formation to remain.
