Old Case Record: the Situation of No One to Return

Three years ago, a major case occurred in the "Wuluo Ancient Village" on the outskirts of the city where all employees were killed in the line of duty. All on-site evidence was artificially destroyed, files were tampered with, and insiders were silenced. It was classified as an "accident." The suspended heroine Shen Yan still doesn't believe in the conclusion. An accidental splicing of clues from old cases leads her to meet Lu Ci, who specializes in taboo unsolved cases. Starting from the scattered cases of strange disappearances among the people and bizarre murders in forbidden areas, the two discovered that all the seemingly unrelated strange cases contained the same secret symbols and crime logic, all pointing to the mysterious organization "Guixu Society".
