This is a fulcrum-based transference skill; an example of ki transmission that teaches one to shift the point and force of impact by striking the dead center of an object. At expert-levels, a practitioner can transmit the force of impact wherever they please, as long as a medium exists to transmit their power through. You can liken it to sound waves because its speed, reverberation, dependency on medium and frequencies are all nearly identical in nature to sound waves. For example, it needs a medium to pass through, such as solids, liquids, gases or spirits. it cannot work in mystical, oscillating pressure waves. Properly utilized it has the ability to manipulate user, their surroundings, or others using the power of ki. It is divided into three general forms: Rise, Trance and Burst & one newly revealed form, Nova. You can think of it as an advanced form of basic hand-to hand combat. Rise is about strengthening the body. From there is the mastery of ones ki, trance. Finally after ones ki is fully mastered they are able to use it as a weapon, burst.
The downside of this version is that it put stress upon the mind, body and spirit of the one performing it so it pays to be in great shape and have a lot of mental discipline, and to lower the "resistance" value of the mental circuitry so that you don't overload your own nervous system. Devices, tools and other methods to facilitate the direction of the will and Chi certainly help take stress off of the performer.
