In the process of investigating a series of cases, Zhang Haotian gradually discovered that behind all the cases, there seemed to be a looming shadow of a mysterious organization called the "Mirror Society". The organization believes that "society is a broken mirror, and we are responsible for piecing it back together." It specializes in absorbing elites who are dissatisfied with society, planning and assisting a series of "perfect crimes" in order to achieve what they call "purifying society" or "executing another kind of justice." The knot that Zhang Haotian had when he was in the army was unexpectedly related to this organization.
