Even before the fifth Retrospection, when he returned from setting foot on Immortal Island, Casio began to grasp the key to unifying three Boxing Methods into one during the process of writing the Southern Dipper Secret Transmission. Later, after experiencing the Sixth Retrospection and the practices in the Real World, a plan began to take shape in his mind.
First, the unification of the three fists can be explained as two powerful concepts.
The first concept is the merging of the Southern Dipper Secret Transmission, the Water Bird Fist, the Red Vulture Fist, and the Sound Snake Fist into one. No longer separate, no longer diverging, but returning to the essentials and merging into one! Transforming into a complete and true "Southern Dipper Secret Transmission."
It becomes a mythic legendary technique that completely transcends the first-class Secret Martial Arts.
