Lin Mo, an ordinary young man, was involved in the dispute between the Yin and Yang worlds because of a mysterious bronze mirror. The ghostly hand in the mirror dragged him into the intersection of Yin and Yang, which also triggered strange events in the real world: corpses disappeared from the hospital morgue, and subway passengers died mysteriously. At the same time, an ancient temple that had been dusty for thousands of years emerged from the ground, and the ancient Taoist priest Xuan Xiao, who had lost his memory, awakened from it. Xuan Xiao sensed Lin Mo's unique yin and yang eye aura and forced him to become his partner by force.
