The true heiress, raised in the barren mountains, has just returned to the estate when she kicks over the fake heiress's spirit-recruiting banner, burns her blessing-stealing talisman, and casually subdues a century-old tree demon to serve as her maid. Prince Regent Ming Xuanye is born with a malignant constitution, and in the entire Great Xia, only she dares to get close to him—yet the Crown Prince has long locked the cinnabar pearl capable of healing his legs into the Lishan Altar. Bringing her black cat down the mountain, she shakes Shangjing overnight. Fighting her way to the foot of Lishan Mountain, she discovers that the chess game of healing legs and seizing the heir apparent has been laid out for her fifteen years ago.
