"You want to use the Mind Switch technique to trigger everything associated with extreme starvation?" A Martial Squire frowned at Rui.

Rui had opted for the guidance of a mind-oriented Martial Squire to guide him in the mastery of the Mind Switch technique. Squire Juvier's face had scrunched in confusion when he learned of Rui's objective of trying to trigger the sensation of extreme starvation using the Mind Switch technique.

Normally, people learned this technique to retain calmness and composure in the middle of combat. There were many Martial Artists that found it difficult to retain calmness and composure in highly dangerous situations. In such situations, fear and panic could cause them to act in sub-optimal ways, increasing their probability that they would make mistakes.

The Mind Switch technique was created to give Martial Artists a way to reduce the probability of such things happening to them. It allowed them to hone their mind and impact it favorably.
