This technique to transform one's body into a liquid, Noland learned from Selena, is a magic taught by the Deep Sea Branch and is called the "Liquid Transformation Technique," which is applicable to both Water Clan and Deep Sea System magics.
When turning into a liquid, the body part would retain its normal sense of touch and could even split from one water stream into several.
Each water stream would be able to flow into different pipelines while still retaining their sense of touch.
After becoming proficient, one could use the liquid transformed hand with more than ten water streams to simultaneously control more than ten magical devices on the magic yacht, just as Hadley Grant does now.
Hadley used his liquid palms to close the yacht's ventilation and drainage holes, open the inlet for the water tank on the lower deck, and activate the magic circle that poured freshwater into the tank.
