The day her fiancé publicly broke off their engagement, Shen Zhaoyue overturned the ancestral tablets in the Shen family shrine and set the clan genealogy ablaze with yin fire. She didn't know she was the kindling for a thousand-year-old yin meridian, nor did she know that Xie Linyuan, the cold and indifferent judge, had once sealed away her mother's soul with his own hands. As the yin fire blazed, the yin market fell into turmoil, human lanterns awakened, and ghost mirrors whispered. When Bai Wujiao's blood curse intertwined with Liu Qingwu's shattered dreams, and the wronged soul in Gu Jiuyuan's mirror began demanding lives, Shen Zhaoyue finally understood: what she had kindled was not hatred, but the fire of atonement buried by the Heavenly Dao for a thousand years.
