Night Demons might be considered the weakest among the demon race before reaching the Demon Core or Demon Soul Realm; however, their innate ability was terrifying. They could perfectly conceal their breath and aura.
Thanks to appearances that mirrored humans completely, combined with this innate ability, they could easily slip into human society without raising suspicion.
When a Night Demon fully activated its concealment, even Nascent Soul Realm cultivators would find it extremely difficult to discern their true identity.
Even Ethan's [Azure Snake Eyes]—a power that could normally pierce through most disguises—failed to distinguish them.
From this alone, one could understand how fearsome a Night Demon's innate gift truly was.
Thus, all the core disciples naturally turned to Felix, the so-called Holy Son, for help in finding the hidden demons.
"Of course."
Felix's lips curved into a cold smile as he stepped forward, walking leisurely toward the first group of captives.
