Rui gritted his teeth day in and day out as he continuously experienced starvation and torture. He had underestimated the sheer mental fortitude required to master the Mind Switch that he had aimed to master.
The technique was grade-three as far as the difficulty of mastery went, the problem was that it was rated as a technique with low difficulty of mastery because most applications of the technique were to be able to trigger calmness and composure in the Martial Artist aspiring to master the technique. The best part about the technique, when applied this way, was the fact that it was relatively straightforward and didn't need any severe exertion from the Martial Apprentice.
However, Rui had gone far off the normal path and used it to try to trigger the neurological phenomena associated with hunger with pain.
This was something Squire Juvier still found absurd and stupid.
