Reagent Instructions

Four "suicides" and four deaths were all related to an old incident three years ago. Under the pressure of solving the case within a deadline, criminal police captain Wu Jiang discovered that all the evidence pointed to a chemical reagent that should not exist. When he tried to trace the source, the ban from his superiors, the resistance from the school, and the silence from the victims intertwined into a huge web. Wherever the reagent flows, the secret is automatically dissolved. The only flaw Wujiang holds is pointing to the city's bright future core. Should we reveal the truth or obey the rule of "silence"? What he faced was not just a murderer, but an entire system guarding a certain secret.
