By the time Sun Daoyuan sensed the presence of the Demonic Qi, it was already too late. Those Tribulation Strength Demon Beasts crazily transported themselves from the Dark Abyss, revealing their massive forms and piercing directly through the top of the Cave Mansion nestled in the mountains.
The first few Tribulation Fiends to emerge, after piercing through the mountaintop, emitted a glow and exploded instantly. The Demonic Qi released from their bodies spread rapidly, transforming the surrounding land into a Demon Domain.
By then, Sun Daoyuan had already deployed his protective spells and escaped from the mountains. Witnessing the scene before him, his expression changed. What on earth was happening? He was merely healing and cultivating in this place, but unexpectedly, he had encountered an attack by Demon Beasts, and what was more, he had failed to detect them at all.
