Charm and Illusions
Mira opened the last book, [How to Utilize the Strength of Your Body in Long-Range Fights] that the Sect Master had given her, but there wasn't much to it. It basically just said that if her physical body was strong enough, there was a way to attack her opponent from a distance without Qi.
The way to do this is to strike with overwhelming power. However, the strikes have to be straight and precise-no swinging motions, roundhouse kicks, or anything like that. Doing that would diminish the power one can unleash along with the range of the attack.
Basically, the book is telling Mira to punch so hard in a straight line that the force of the punch travels through the air and hits her target. The best way for Mira to describe it is to combine boxing with a wind tunnel.
Mira was already doing this, but it seemed Sect Master Aelina wanted her to devise ways to incorporate this into her fighting style since punching and kicking with a massive scythe isn't feasible.
