Unexpected things happened.
Casio originally thought that the Holy Springs Water was just a unique life energy, which could be used to strengthen the body and nourish the spirit. But unexpectedly, the Holy Mark condensed from drinking a certain amount of Holy Springs Water had an effect on a fighter's Qi!
Although it's still unclear what's going on, one thing is certain. He must get more Holy Springs Water.
Likewise, it isn't just for restoring his strength.
It's also for the higher-level transformation of the Secret Martial Art boxing method.
Casio has a premonition that this Holy Mark, which originated from the Holy Spring, is absolutely a good thing, at least, it is for the Southern Dipper Fist.
In the end, he conducted some research and tests. Then, he called the doctor from the sanatorium and expressed his intentions to leave.
After some checks, Casio left the ward successfully.
Before leaving the sanatorium, he found a mirror.
