The Bai family has practiced the mystic arts for a thousand years, with ancestral skills for communicating with the worlds of yin and yang and discerning ghosts and spirits. But as their bloodline dwindled, the family fell into decline. Then the girl Bai Lili was born with naturally gifted yin-yang eyes, and mastered any spell at a touch. Her family saw her as their hope for a revival.
She does not know that she is the reincarnation of the Bai family's legendary ancestor, once a judge of the underworld. When the seal on the Ten Thousand Ghosts Cave, dormant for a thousand years, begins to weaken, vengeful spirits emerge and ancient enemies return to lurk in the shadows. Only then is she forced to awaken the judge's memories and powers within her.
Wielding the Judge's Brush and commanding the Book of Life and Death, she opens the gates of the underworld and guides wronged souls onward. Bai Lili must shoulder the mission of her past life and, amid the protection of her loved ones and clashes with her old enemies, set out to reinforce the seal and restore order between yin and yang.
The gates of the underworld are open. The judge must return. In this life, she will lead her family back to its former glory and once again judge the good and evil, yin and yang, of the mortal world!
