Having spent half the day with only a 'very healthy body' as a conclusion, this was undoubtedly a heavy blow to Master Ruvie. He had to acknowledge Ya Ya's uniqueness, but could not give a correct and reasonable explanation.
Of course, this was under the condition that he did not resort to extreme measures. Ruvie felt that if he dissected, sliced, labelled Ya Ya in the same way as he did with Cordova, then he might be able to draw a conclusion from a microscopic perspective. But he clearly couldn't do this because Ya Ya, unlike Cordova's runic body that could be dismantled for fun, was a legitimately living girl. Although it was easy to dissect and slice, the crucial issue was that she definitely wouldn't be able to be restored afterwards. Master Ruvie might be stubborn, obstinate, irritable, and close-minded, but he couldn't bring himself to indulge in such crazy operations. This was his pride and bottom line as a research scientist.
"So, that's what happened."
