I've reincarnated, and into the world of 'that' book. And I've reincarnated as, Valier Pendragon, the adopted child of the Pendragon Archduchy. Valier was actually a rather unimportant character, but he was a villain.
'For example, If it is a burning flame then it will return to its neutral state and become simple neutral atoms. As for a flying rock, then it will lose its momentum and return to a simple unmoving rock.' I theorized but I still needed to test my power under various conditions.
During the few years after my reincarnation, I couldn't even move my body as I wanted to and even though it was embarrassing, my mother took care of all of my needs even though I was a 30-year-old man on the inside.
