Over the next few days, Rui immersed himself in the newest idea for his Martial Art technique. A technique that could allow him to read his opponent's mind to some degree by hypnotizing them such that their non-verbal communication reflected their mind to a certain degree.
This was possible if one was in a trance, which was a state of semi-consciousness. In this state, the subconscious mind gained greater control over the body. What Rui was particularly interested in was the fact that he could read what the subconscious mind was conveying much more easily.
Thus, in regards to the catoblepas, Rui needed to develop a technique that put them in a trance where they would relive the memories of the Divine Doctor. He could trigger them into doing so by showing them the visual depiction of the Divine Doctor as he had before, except, this time, he would be doing it to them while they were in a trance.
