Almost at the same time, furious roars suddenly erupted from the depths of the activated Primordial Demon God Blood God Grand Formation.
Those roars were like thunder, like heaven collapsing and earth splitting apart, causing the already-formed Bloodlight Aura to churn like a tsunami.
The same was true at Laiyang Fortress and Ningchuan Fortress.
Countless Devil Race experts cultivating within the Bloodlight Aura were blasted out by the tsunami-like impact of that blood energy's Negative Energy.
Those less severely affected suffered violent shocks to their internal organs and spat blood wildly. Those more severely affected were battered by the vortices of blood energy until their bones broke and sinews snapped.
Quite a few unlucky ones died miserably on the spot.
Yet the greater commotion came from the third layer of the Bloodlight Aura, where only Dao Realm experts and true Devil Race nobles could enter to cultivate.
Those furious roars were like demonic sounds drilling into their brains, shaking their primordial spirits violently and leaving their bones weak and sinews limp.
They exchanged horrified looks and turned toward the deepest part of the grand formation.
To them, that place was also forbidden ground.
Yet those angry howls had clearly come from there.
Before long, this drastic upheaval spread upward and reached the Demon God Palace. At the same time, Demon Emperor Second Crown Prince Zhui Ri, who had just captured the Blood River Forbidden Zone, also received the news.
After receiving the report, the Devil Race higher-ups led by Demon Emperor Second Crown Prince Zhui Ri stared at one another, unable to understand what had happened.
Suddenly, Wa Ling Holy Son Yu Shou rushed over with a ferocious expression. "Where is Ye Zhen?"
"Where is that bastard Ye Zhen? And why have all the troops under his command completely vanished?
