In the Master Realm, it is required that thirty-two out of the one hundred and eight acupoints within the body must be open. Only then can the Small Heavenly Circle form within the body, under which the Qi-Blood circulates endlessly, and the force cultivated within the body can also be concealed within the acupoints.
The force exerted through the acupoints of the Small Heavenly Circle is called Hidden Power.
The core of Hidden Power is to conceal the combined internal and external force within the thirty-two acupoints, allowing it to flow in a full circle and, when action is taken, the Qi-Blood instantly surges, sending the energy hidden in the acupoints to the viscera, inner membrane, and limbs, thereby unleashing formidable combat strength.
