What's the Big Deal About Me Having a Ghostly Senior Sister as a Yin-Yang Master?

My name is Wu Yuechu, and I was born on the fifth day of the fifth lunar month. Ever since I was little, I had an unusual ability: I could see things that other people couldn't. To keep me safe as I grew up, my grandfather sent me to a Taoist temple far from the bustle of the city when I was young, where I could practice my cultivation. As the years passed, I spent a carefree childhood at the temple and learned many ways to exorcise ghosts and drive away evil spirits from my senior brothers and sisters. Only after I had grown up did I reluctantly leave the temple and return to the mortal world.
