"Predator Feather" imitated top predators, allowing martial artists to move at high speeds while still being utterly silent, making it an essential good for assassinating, robbing, and for home travel.
Lu Li learned quickly, and within half an hour, he was able to create a "tiny serrated" structure of True Qi on his body surface.
He practiced his movement technique by running around the yard twice and then flew into the sky, circling for quite some while, all the while making only minimal noise, similar to the sound of tossing out a piece of clothing.
"The structure of this True Qi indeed helps reduce air friction and greatly eliminates noise. But it uses additional energy, suitable for stealth techniques,"
Lu Li found it interesting, and he remembered Ito Taitaka whom he had previously killed, who moved in such a silent and unpredictable manner, likely using a similar principle.
