Grand Hall
Ryu had come to realize that the puzzle existed for a reason.
With how unorthodox the formation had been, why shouldn't the rest of this Ruin be just as unorthodox? In addition, whoever had left behind this formation wanted the person who claimed their inheritance to understand this unorthodoxy. If they couldn't, then how could they allow such a person to enter their holy grounds?
That was when Ryu came to realization that using symmetry to try and understand asymmetry was foolish. First he had to shift the foundation of his Matrix to better match this environment, and only then would it have the ability to calculate properly.
Almost immediately, the last calculation that Ryu had commanded the Matrix to finish, the very one that had almost overloaded it, finished in the blink of an eye.
