Female Feng Shui master Lin Shutong took over the "haunted house cleaning" business due to the mysterious disappearance of her mother twenty years ago. When dealing with the mysterious case of "old-fashioned landline ringtones that ring on time every night", she accidentally discovered that all the murderous ringing incidents pointed to a mysterious organization that uses "sound waves" to control people's hearts. Relying on her ancestral Feng Shui skills and psychological profiling skills, she successively solved the mysterious cases such as blood letters in ancient houses, murders in the mirror, and auditory hallucinations of evil bells. She gradually uncovered the connection between her mother's disappearance and her "sonic sensitive constitution." The full text uses strong reversal unit cases to connect the main lines, focusing on "Feng Shui Breaking + Psychological Counterattack + Uncovering the Truth Layer by Layer".
