Warped
Ryu's [Vector Eagle] was exceptional. Became of its incredibly slim and thin design, it had to deal with practically no air resistance. At the same time, Ryu managed to keep [Piercing Ballista]'s malleable mercury body, thus allowing Ryu to change [Vector Eagle]'s form as he pleased. Minor changes in the technique's wings gave it a maneuverability [Winding Arrow] could only dream of. As for its piercing power, this hardly needed mentioned. With such a slim formfactor, how could it be lacking.
'To think Little Ryu has such talent in the Mental Realm…' Though Ailsa thought this, she wasn't too surprised by this turnout. Those who wielded the Mysteries of Heaven and Earth pupils in the past often migrated toward the Mental Realm as well.
Though the pupils were obviously also greatly beneficial for the Qi and Body Realm, it was far easier for them to turn their comprehension into strength in the Mental Realm.
