Yang Yin was born with yin bones. The village elders called her a girl who brought misfortune to her father and family.
From the day she was born, she was treated as an ill omen and left to live in a ruined temple at the end of the village, where she spent her days among incense, dying candles, and lonely ghosts. She could see the sinister beings hidden from ordinary people and hear whispers from inside coffins. But all of this was only the beginning of her fate.
A hundred-year-old villager passed away peacefully, yet strange events plagued the day of his burial. The coffin sank three feet into the ground, dark red stains seeped through its wood, and even the Taoist priest was driven back by an ominous force. The elders declared that only the girl with yin bones could carry the coffin and calm the evil energy within, allowing the dead man’s soul to pass into the underworld.
Yang Yin was forced in front of the coffin. The moment its icy surface touched her palm, she heard a clear voice calling from within. An invisible force wrapped tightly around her. The coffin crushed down on her, and her soul felt ready to split apart. Just as she was about to suffocate, a figure in dark robes burst through the yin energy, surrounded by surging malice. It was none other than Fu Jinming, the Ghost King who ruled the underworld and commanded all ghosts.
He had come for the vengeful spirit inside the coffin, but was unexpectedly drawn to the aura of yin bones surrounding Yang Yin. Her yin bones were the only key capable of breaking the thousand-year-old shackles binding him. From then on, the Ghost King accompanied the girl with yin bones on her path of carrying souls.
Coffins conceal evil, and yin spirits claim lives. Ancient taboos hidden deep in the village, the truth behind Yang Yin’s supposed curse on her father, and the Ghost King’s thousand-year obsession are gradually brought to light. Every coffin she carries is a struggle between life and death; every soul she guides draws the two of them closer to their entwined fates.
