Founded by Sun Moon Cult Leader Ren Woxing, it is an internal mental skill created through a combination of good and evil Chi. If successful, your Chi paths become unobstructed, and the body feels empty and clear, one can freely absorb or dispel energy. It has been said that if successful in learning the skill, one would be one with heaven, with the power to yield the sun and the moon. One can easily absorb or dispel energy from others or effortlessly capture objects in the air. It is indeed an unparalleled, arrogant, and indomitable skill.
