Yibai's movements were not at all secretive within the Three Realms,
The changes among the low-level soldiers at the Northern Celestial Gate, whether by the doing of Emperor Zhenwu or simply due to negligence, unexpectedly allowed Yibai's Celestial Soldiers to grasp the situation completely in an instant.
Yibai began to move troops and issue commands, seemingly heralding that the conflict would soon escalate. Quiet changes took place in many areas of the Lower Realm, some propagating the theory that the Heavenly Emperor lacked virtue, some participating in the suppression of the Taoist Sect, and still others, completely befuddled, indiscriminately targeting the Buddhist Sect, leaving the Bodhisattvas and Arhats of the Buddhist Sect dumbfounded, despite the matter seeming unrelated to them.
The entire Lower Realm and the Celestial Court were trending towards chaos.
Yibai, however, had no interest in paying attention to these events continuously.
