To cultivate the Starry Mirage, he would have to find a starry source or a region with the power of stars. As long as he was able to do so, he would be able to establish a firm foundation on the technique.
"Interesting, starry power is something only Yin Lords are capable of refining, Tsk! Tsk! This might be troublesome" Xiao Ming snickered lightly after getting to this point in the description.
Also, on reaching the small success stage officially, he could casually shift positions and create the mirage or illusory images of star constellations on the battlefield. The opponent would be unable to tell Xiao Ming's location and chaotic movements as he had induced a field of stars and with a thought, he could assume the position of any 'star'.
