Qi Zhiwei, a talented girl from Tianjing, lost her eyesight in an accident and fell into endless darkness. In desperation, the "audio and truth identification system" was activated, and her hearing was extremely strengthened, allowing her to hear the wind and hear things, and gain insight into people's hearts. From then on, she used her ears as eyes and transformed into the "non-staff Shunfeng Er" of Dali Temple, assisting Shaoqing Li Yuan in solving a series of strange and unsolved cases. The sounds of everything from the noisy streets to the deep mansions and courtyards are clues. However, as the investigation of the case progressed, she discovered that her blindness was not an accident, but was actually closely related to the ancient and mysterious "Tingyin" sect, and even more implicated in the monstrous conspiracy hidden behind the Zhou Dynasty. How will she use her ears to clear the fog and see the "light" again?
