If the water flow branched off, turning into numerous streams, it would pour out.
Then, when your fist hits the wall, the force from the point of your punch would spread to the entire wall, creating dense cracks.
The fourth technique is Dissipating Force.
This is a combat skill, akin to punching a piece of thin fabric that is hanging up; the fabric does not retain the force. It involves relaxing all the joints and muscles in the body, turning them into something as frail as the fabric, swaying like thin bamboo in the wind. At the moment of impact, the body moves and sways with the force like cloth.
However, according to Chen Liao, applying Dissipating Force also depends on the structure of the body.
The human body, being a physical structure comprised of densely packed bones, can move freely. If an opponent's punch is incoming, and you thrust the impacted area forward before the attack lands, the natural instinct is to pull away.
