[Rat Cat] Like a Song Turning to Cinnabar

This... I don't know what kind of introduction to write for the moment, but it's the series of songs like Wan Ruge anyway. It can be considered an attempt at a long fanfic and a crime-solving theme. Actually... This is an old article that was posted before in Zongheng. The purpose of posting it here is to remind myself that there is still a hole to fill every time I come to this column.
