Within the Blood-Devouring Spirit-Nourishing Formation, the two Foundation Establishment Realm Ruin Beasts had gone utterly blood-mad. Cultivators' blood stained their bodies as they slaughtered without mercy.
In just a few breaths, another dozen or so cultivators were killed. Their falling blood essence was absorbed by the Blood-colored Grand Formation, nourishing an unknown Spirit Treasure.
"Kill! Buy Fellow Daoist San Zui an incense stick's worth of time to break the formation!" a cultivator roared, treating Daoist San Zui as their last straw to cling to.
Xu Yan mingled among the cultivators, summoned his ink-black flying sword, and attacked alongside them.
Boom!
A terrifying explosion rang out. Nearly a hundred cultivators attacked at once, engulfing the slightly smaller Ruin Beast in all manner of magic artifacts and spells. The violent magic power spilling out inflicted considerable injuries on it.
Roar!
The other, slightly larger Ruin Beast was struck at the same time and let out a shrill scream.
Seeing their combined strength instantly injure both Foundation Establishment Realm Ruin Beasts, the cultivators' confidence soared. They looked ready to slaughter both beasts here in one fell swoop.
Xu Yan took in their reactions, but different thoughts arose in his mind.
Awooo! Awooo!
Two deep, far-reaching beast howls resounded throughout heaven and earth. Blue-black light surged around the two Foundation Establishment Realm Ruin Beasts, and a cold, sinister aura gathered over their bodies.
Roar! Roar!
Two streaks of blue-black light instantly shot from the Ruin Beasts' mouths, hurtling toward the crowd!
Rumble!
The two streaks of blue-black light rapidly swelled in the cultivators' eyes. Their thunderous roar shook the heavens like thunder crashing from the highest skies, leaving everyone trembling with fear.
Only when they drew closer did the cultivators see that the two streaks were composed of countless densely packed blue-black wind blades.
