Lu Li, an ordinary young man, awakens the ability to sense the city's "silent echoes" after an elevator accident, and is forced to be involved in a series of urban weird incidents. This volume focuses on how he went from passive perception to active exploration, using his abilities to solve the first few abnormal events, and initially understanding the abnormal world hidden in daily life. At the same time, he fought against the mental erosion caused by his abilities, and attracted the attention of the authorities and other forces.
