In the context of modern cities, the "Age of Ending Dharma" with declining aura ushered in a once-in-a-century "spiritual tide". The Yin energy recovered first, evil spirits breed, sleeping Taoist forces, ancient inheritance and hidden alien existences gradually emerged, and ordinary cities became a stage for extraordinary power games. The protagonist Lin Mo, as a descendant of a declining Xuanmen family, awakens in the surge of spiritual tides. With the ability to combine traditional Chinese medicine and mysticism, he gradually uncovers the truth about the spiritual tide, protects the city and the people around him, and finally embarks on the road to reshape Xuanmen and balance the world of humans, ghosts and monsters.
