Bias Release (偏倚 解放) is a Magic that creates an explosive shock wave upon contact with the desired target by shooting a compressed block of air. Convergence Type "Bias Release" is highly convoluted and inefficient, thus making it a second rate magic.
The normal way to use this magic is to compress the atmosphere on one side, than force its release at an angle, at high pressures. Its process is similar to pumping air into one side of a can and sealing it, then opening the other end towards the target. This creates an advantage where the concentrated compressed air would strike with greater force and higher control over the direction of the force than normal air.
