In a modern urban setting, a once-in-a-century spiritual tide arrives in the “Age of Declining Spiritual Energy,” a period when spiritual energy is fading. Yin energy revives first, giving rise to evil entities. Dormant mystical sects, ancient inheritances, and hidden beings from other realms gradually emerge, turning an ordinary city into a battleground for supernatural forces. Lin Mo, heir to a fallen family of mystical practitioners, awakens amid the surging spiritual tide. Combining traditional Chinese medicine with mystical arts, he gradually uncovers the truth behind the tide and protects the city and those around him. In the end, he sets out to rebuild the mystical sects and bring balance to the worlds of humans, ghosts, and monsters.
