Lin Yu was an ordinary college student until an encounter at a secondhand bookstall drew him into the mysterious world of yin and yang. From then on, he mastered yin-yang magic and teamed up with Su Yao, an enthusiast of the supernatural, to investigate the truth behind a wave of strange incidents in the city. It turns out that an evil force is plotting to shatter the balance between yin and yang and unleash ancient fiends. Can Lin Yu use what he has learned to protect the order of yin and yang alongside his companions and avert this world-shaking crisis?
