This was the plan that Rui had devised after realizing that the Divine Doctor had gone to the Garden of Salvation. The moment he realized that they needed to enter the Garden of Salvation, he knew that they could not find it through physical search.
After all, that was why the Divine Doctor had chosen such an intricate and elaborate plan to extract all the fear from the Forest of Fear.
It was all for the sake of entering the Garden of Salvation.
Rui didn't feel the need to reinvent the wheel.
The Divine Doctor's solution was ingenious, and Rui would most likely have arrived at the same solution himself.
