No Forbidden Area Ancient Emperor can possibly pledge allegiance to anyone!
This was an iron law in the past, with no exceptions ever occurring. These Forbidden Area Ancient Emperors were too proud and confident, significantly preventing them from forming an orderly hierarchical organization.
But now, things are different.
The Green Vine Ancient Emperor, Vermilion Bird Ancient Emperor, and other Ancient Emperors have been promoted to Forbidden Area Ancient Emperors in the Supreme Great Sun Domain. They feel deep affection and have great confidence in the future, thus choosing to pledge allegiance to the Supreme Great Sun Ancient Emperor, jointly pursuing the Immortal Path. Most importantly, the Supreme Great Sun Ancient Emperor never once deliberately suppressed talented cultivators in all of history to avoid threats to his own legacy.
Such political credibility is extremely precious.
