Master of myself

Sitting in a cool palace our protagonist is met with a great challenge, a peice of paper asking what abilities he wants in his new reincarnation into a magical reality. Easy, he already though of it, he wants complete control over himself and anything a part of himself. Using this ability he will do cool things probably.

Note, unplanned writing out of boredom don't expect a lot, or good, chapters. Xianxia is there, but it is mostly about magic and not martial arts, just that you get to do the Xianxia things of imortallity and divinity if you are strong enough, and side characters will cultivate normally.
