The words of the Juhe King were like cold water being splashed on everyone's faces.
The expressions of the kings darkened, and a little fear rose in their hearts.
"Other than the initial loud and screeching sound, this attack has no other traces. I'm sure all of you sensed that the energy wave didn't even have any spirit Qi in it." The patriarch off the Dark Plains sect said.
"Indeed… if it was used in a closed space… like the underground, no one will hear its initial activation." The King of the Zhan Kingdom agreed.
"And not being a physical or spirit Qi attack… it might not even be registered by an array." The King of the Peony Plains Kingdom added.
Everyone present felt a collective chill going down their spines as the realization downed on them.
All of them had the same thought, if a beast like this was unleashed on their territories, what was there to stop or even detect it?
