Special Affairs Investigation Record

The universe is filled with sound. But not all voices can be heard, and not all silence means nothingness. Located in the space station at Junction 86 in the solar system, there is a special affairs investigator named Xing Yi. There is a sign hanging on his office door: "Special affairs investigation - non-criminal, non-civil, non-known area." That's not an exaggeration, it's a job description.
