Lin Wanxing, the heroine of the Guardian of the Spiritual Eye, has been hearing sounds that others cannot hear since she was a child. She unexpectedly uncovers the mystery of her mother's inheritance and encounters the Shadow Clan who covets the altar of the Spiritual Eye. From An An in the Sunshine Welfare Institution, Li Mei in the abandoned factory, to Shen Manli in the old record store, she connects every obsessed soul with kindness; while police officer Lu Ze is always by his side, and the guardians of the Lingyan family come across time and space. When the shadow clan's coldness shrouded the ancient well, and when the abnormal changes in the water veins affected the safety of the whole city, Lin Wanxing finally understood: the power of the spiritual eye is never fought alone, but with goodwill as a bridge and inheritance as a shield, so that every warmth becomes the light that protects the fog city.
