The distance of three meters was not a great distance even for a creature as small as a sylph. Nerphyl could have flapped her wings and jumped flying then landed on Moku's shoulder in an instant. But three meters will be a different story when Moku releases his killing intent in full.
Moku is a being who has crossed the limits of his astral body, so it can be said that the possibility of an orc capable of colliding with him is completely non-existent. Transgressing the limits of the astral body also means that Moku has reached the perfect point of body development in this world.
You can imagine how it feels to face the killing intent of such a creature. A sylph who dares to face Moku's killing intent is like a rabbit fighting a dragon's roar. But luckily Nerphyl was a rabbit who wasn't afraid of the dragon's roar.
