The reason why Zachary could detect such subtle vibrations was that ever since he had entered this plane, he had been constantly using his Divine Sense to scan his surroundings.
As a result of the energy consumed, Zachary had maintained a detailed scan within a hundred meters, which naturally enabled him to detect the ground vibrations immediately.
