"Kid, who exactly are you?"
Commander Situ and the Fifth Guardian instantly abandoned their previous disdainful expressions.
Instead, there was a hint of wariness.
Yes, wariness, not solemness or surprise.
"The Ten Realms Destruction Formation is one of the ancient murderous formations; this formation has long been lost."
"It's only preserved among some ancient forces."
"Even within these ancient forces, not everyone is eligible to practice it."
The two were not wary of the formation itself, nor Xiao Yi's power.
What they dreaded was whether Xiao Yi had another identity.
Xiao Yi remained silent, his palm moving slightly, as if preparing something.
In fact, he couldn't employ the Ten Realms Destruction Formation and didn't know how to either.
The true Ten Realms Destruction Formation involved setting up the formation, which then generated the Ten Realms Annihilation Fire to kill enemies or produce various effects.
