When I opened my eyes, my father was a doting girl and a Feng Shui master who understood both black and white, and my grandfather was an orthodox descendant of Maoshan. As a blessing in disguise, she awakened the physique to freely travel to and from the underworld, and became a "Yin-walking Genius" who can communicate with Yin and Yang. Underneath the fairy-like appearance, he is a walking defender of the yin and yang order.
