"The secret to immortality?"
These words from Ripple Master Mongki piqued Casio's interest, but only slightly.
The curiosity in his heart wasn't strong; he didn't experience the ecstatic joy common humans felt upon hearing they could attain eternal life.
Theoretically speaking, Casio's current realm was already not far from immortality. The Saint Fist! By using an endless and ever-growing Qi as a foundation to carry will, one abandons the constraints of flesh and transcends the human limit of life. Lifespan becomes exceedingly long, almoust immeasurable.
Throughout the World of Calamities, it seemed no Saint Fist had ever died of old age. They either died in battle or perished from exhaustion; no Saint Fist had died a natural death to date. And referencing the lineage of the Southern Dipper, each of the three Southern Dou Holy Fists were born in the ancient times and existed for tens of thousands of years.
