Sunan heard this and just curled his lips without saying anything.
The others might have only seen the description of the Banshee's wail in ancient texts, not really understanding it, but in his past life, he had witnessed it with his own eyes.
The true Banshee's wail is indeed a power that even an Official Wizard dreads.
If this divine creature had unleashed the true Banshee's wail, Rose, Night Owl, and the others wouldn't have escaped here at all!
The so-called Banshee's wail was at best a similar type of sonic ability, much like the sonic attack used by the Funeral Bell makers.
That being said, for this divine creature to easily take down Red Heart, its power level definitely reached Tier Four Legendary, maybe even stronger.
Thinking of this, Sunan's expression also grew more solemn.
"Chirp chirp!"
