Magic?

Fantasy movies have long depicted warrior/sages of the Wudang Mountains and wizards wielding uncanny powers.
Masters perform unlikely feats of physical prowess and people fly through the air.
But is there any truth to be found behind the legends, folklore and myth?

The exaggerated feats shown in the movies stem from both awe and ignorance.
Internal martial arts do offer amazing, uncommon skills, but they are not magical.
Consider the Wang treatise:
 

The spectacle of an old person defeating a group of young people, how can it be due to swiftness?

(Wang Tsung-yueh)

Neigong leads to jing (internal power).
Internal power has been sought after in China for millennia.
