Merlin flicked her fingers and turned on the shower, letting a gentle stream of warm water pour out. Hundreds and thousands of tiny droplets hit her hair and slid down her pale skin, finally ending on the marble floor beneath her feet. For a moment there, the water felt cold, but quickly got warmer and warmer until it steamed.
Standing still for a few seconds and letting her skin and hair soak, Merlin closed her eyes and focused on the flow of mana going through the tubes alongside the water, and followed it all the way back to the magical boilers. Unlike the maids, she didn't need the control panel and could directly hijack the magical circuits of the boiler from anywhere.
