The three formations completely enveloped the ten-mile radius where the demonic qi erupted, and also covered the East Spring Undying Bone. The trapping formation was invisible, seemingly present everywhere. The killing array appeared in the form of a silver-white sword net, standing alongside the trapping formation.
The thunder array was on the outside, transforming into a lurking serpent constantly weaving between the two formations like a living creature. Whenever any demonic creature approached within fifty miles of the three formations, the thunder serpent would strike with lightning speed.
As the three formations took root, although not of the Tier Three Top-Grade Grand Array level, its lethality was not much different.
