Chapter 193 (2/2)

On the day at which the water system was working, the Prince called all of the witches to the bathroom to let them finally experience for themselves this wondrous achievement.

The water tank in the backyard was filled with water, so when he turned on the faucet, the water rushed out of the pipe.

“From now on, there is no longer the need to get the water from the well,” Roland proudly proclaimed. “It is not necessary to use the same bathwater for three days. You only have to stand under the shower and pull the lever.”

“Where does the water come from?” Lightning stuck out her tongue and tasted the water, “It’s sweet.”

From below Lighting, Macy stretched out her head and followed her example, “Very sweet goo!”

Seeing a third one trying to taste the water, Roland stopped Nana, “Those who want to drink water, can only do so after it has been boiled. The water from this can only be used for hand washing and bathing.”

“This is… the siphon principle, right?” Anna looked to Roland, her lake like blue eyes flashed with intelligence.

“What is that?” Hummingbird asked as she raised her hand.

Under Scroll’s teaching, every witch in the class had gotten used to the habit of raising their hand whenever they had a question.

” ‘Elementary Physics’ says when the level in two containers is not equal, and if the two tanks are connected by a pipe, no matter what shape the pipe has, under the force of gravity the liquid will always level out.” Anna explained what she remembered, “Our current position is lower than the water tower, so the water will continue to flow to here.”

“That’s entirely correct,” Roland praised. Being able to link the learned knowledge with the reality, really was worthy of a talented person.

“What about this?” Nightingale asked, curiously pointing to the shower, “Why does it have so many holes in the bottom?”

Roland turned the valve open, letting thin water droplets spray out, “It’s for the purpose of making it easier for people to take a bath. Just by standing under the shower, an individual can easily clean their body.”

“So that was the reason you were rolling around in the castle this whole week, to make it more comfortable to take a bath?” Lily curled her lips and whispered, “It’s really worthy of the luxurious life of a Lord.”

“Lily!” Scroll scolded with a frown.

“Never mind,” Roland waved his hand, indicating that he did not mind her words, “The pursuit of enjoyment is one of the biggest sources of human progress, and I am not an exception to that.”
