Modern young man Lu Qinghe accidentally travels to Qingwu Mountain, where he meets Su Nianling, a disciple guarding the spirit vein. The spirit vein is drying up, the spirit fields are dying, and the mountain sect is in imminent danger. Su Nianling firmly believes in the ancient ritual of prayer, but Lu Qinghe proposes "symbiotic spirit channeling"—guiding turbid energy with good intentions and awakening the spirit vein through balance. Over a three-day pact, the two go from doubt to standing side by side, passing through spirit fields, a herbal hut, an ancient well, an altar, and a bamboo bridge, dissolving the turbid energy of greed and drawing down sweet rain to bring rebirth. Qingwu Mountain turns green again, and they vow to protect the spirit vein—and the human heart as well.
