Ah Yue, the daughter of a pharmacist, was born in a barren mountain village. She climbed cliffs to collect herbs and lived with grass in the mud since she was a child. She has a crush on Shi Sheng, the son of Orion, but she feels inferior because of the birthmark on her face.
When an epidemic broke out, the villagers pointed out that Ah Yue was the star of disaster. When Shi Sheng fell ill and was dying, Ah Yue ventured up the cliff and used the legendary "Moon in the Sky" - the silver moon flower that blooms once a century - as medicine. When she returned to the village, a flash flood hit her. She fell into a quagmire to save her child. The birthmark was burned off by the juice of the grass in the mud, revealing the same pattern as the silver moon flower.
Shi recovered from his illness, but could not recognize Ah Yue whose appearance had changed. On a rainy night, Ah Yue brewed an antidote with the roots of the silver moon flower, and she gradually became transparent due to the erosion of poisonous weeds. At dawn, the epidemic subsided, and the villagers saw a new grass with silver stripes growing beside the quagmire. Shi Sheng inexplicably picked one and pinned it to his lapel. Between the sky and clouds, someone could hear the caressing of grass blades like a girl's chuckle.
Concept: Every life will eventually be integrated into the reincarnation of all things, and the purest emotions will eventually find their home in nature, turning into wind, rain, vegetation or moonlight, and continue to protect the world.
