Although this place belonged to Green's inner body,
he could shuttle through space at will, and could even reach the deepest stone house by merely going through the process of opening and closing a door.
But to draw the Golden Saint there, one must employ the form of "running."
Otherwise,
once the Saint lost its target, there was a high probability it would not continue deeper along the corridor.
Even if one wished to preserve the integrity of the "Movable Deed" and not destroy the overall structure of the castle, one would still open the numerous stone doors set between the castles and gradually discern the physical characteristics of Green's body.
Once he found the black stone door that could lead to the 'Visceral Area,' Green's main body would inevitably be severely affected... and might even lose its fighting capacity.
Therefore,
one had to maintain a pursuit that was "proper yet incongruous."
A series of conflicts bursting forth during the chase was inevitable.
