Modern young man Lu Qinghe unexpectedly travels to Qingwu Mountain, where he meets Su Nianling, a disciple who guards the spiritual vein. The spiritual vein is drying up, the spirit fields are dying, and the mountain sect is on the verge of collapse. Su Nianling firmly believes in ancient sacrificial prayers, but Lu Qinghe proposes 'symbiotic spirit guidance'—using good intentions to channel away foul energy and balance to awaken the spiritual vein. Over a three-day pact, the two go from suspicion to fighting side by side, passing through spirit fields, a herbal hut, an ancient well, an altar, and a bamboo bridge, resolving the foul energy of greed and drawing sweet rain to bring rebirth. Qingwu Mountain turns green again, and they vow to protect the spiritual vein—and the hearts of the people.
