Several years ago, Mira obtained a technique from the Mermaid Queen back in the Secret Realm called the Water Body Transformation Technique. Until now, she hasn't had a good opportunity to use it, either because her meridians weren't strong enough or she was just too busy with other things.
There are 8 Stages to the Water Body Transformation Technique, but what's odd about these stages as they don't necessarily get progressively harder the more you cultivate it. Rather, the 1st Stage is the most difficult as many people's meridians can't handle the weight of the water flowing through them and would burst.
The only thing one needs to cultivate the technique properly is a certain amount of strength to withstand the pressure of the water; that's all.
There are 8 stages to the technique:
Stage 1: Meridian Cleansing
Stage 2: Skin Cleansing
Stage 3: Flesh Cleansing
Stage 4: Bone Cleansing
Stage 5: Marrow Cleansing
