In late spring, rain and mist coil around the bamboo on Qingwu Mountain. Su Qinghuan clutches a well-thumbed copy of Records of Immortal Tales from Qingwu Mountain and sneaks onto the mountain path. She is the youngest daughter of a cloth merchant in town, but she harbors a dream of meeting an immortal and cultivating the Way. She hopes that by doing so, she can protect her hardworking parents and escape the petty troubles and helplessness of mortal life.
An unexpected encounter by a mountain stream brings her into the sight of Shen Ci, dressed in a moon-white robe. He gathers dew at his fingertips and gently touches the space between her brows, discovering that she possesses the rare dual spiritual roots of wood and water. The Pure Spirit Dew he gives her nurtures her spiritual roots, and the method of drawing in qi that he promises to teach her opens the door to cultivation.
But the path to immortality is nothing like the carefree adventures in storybooks. The tedious work of nurturing her spiritual roots, the struggle to draw qi into her body, the lurking beasts in the mountains, and the dangers of unknown secret realms all lie ahead. Meanwhile, the past hidden deep in Shen Ci's eyes and the sect secrets spoken of by a girl in green gradually weave a web entangling her fate.
Bamboo mist blankets the mountains, and a spirit spring reflects the moon. Clutching the cool jade bottle, the girl sets out from the little courtyard behind the cloth shop in the mortal world, taking one step at a time toward an immortal path lost in the clouds. This is a journey about holding on to one's original purpose and growing, as well as a bond hidden among mountain mists and starlight. Now she need only find her own traces of immortality along the path of cultivation.
