Water

"Why water?" Master Ceeran asked with a curious expression.

Rui smiled. "There was a wise martial artist once upon a time, he once said: 'Empty your mind, be formless. Shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot, it becomes the teapot. Now, water can flow or it can crash. Be water.'"

Rui smiled wider as he uttered his favorite quote.

"I see…He must have been quite the Martial Artist," Master Ceeran remarked.

"He was the best martial artist of his time," Rui replied with admiration.

"That saying has much in common with your Martial Art," Master Ceeran gained more interest.

"…I probably wouldn't even be a Martial Artist if I never heard those words," Rui replied.

"Interesting," Master Ceeran remarked. "I would love to meet him someday, if possible."

Rui chuckled. "I'm afraid he is not in this world."
