All of the Primordial Divine Realm warriors have retreated entirely into hiding, as an enemy without precise depth is undoubtedly the most terrifying.
It wasn't easy for them to cultivate to their current realm, and if they do not quickly restrain their aura, their lives would be in jeopardy if they are found.
Some Primordial Divine Realm warriors fled to the Borderlands of the Han Hai Realm to hide, while others dispersed all their clansmen and subordinates, activating all defensive preparations.
This includes the Heavenly Bird Holy Emperor.
The Heavenly Bird Holy Emperor knew something about the Primordial Secret Realm because Shen Lang not only sent a Sound Transmission Jade Slip to Sun Wukong but also sent one to him.
However, when he arrived at the entrance of the Primordial Secret Realm, he was stopped by an invisible barrier and could not enter it despite his Middle Stage Primordial Divine Realm cultivation.
With no choice, he had to return home.
