A brutal massacre that wiped out an entire family set two boys on radically different paths.
As an adult, Shen Ci became trapped in an endless cycle, facing judgment again and again over a long-buried case. He led his team in solving rule-based horror mysteries, tore away the disguises of several seemingly perfect murders, and followed a strand of specially made fiber to track down the observer who had been hiding for twenty years.
This endless cycle was nothing more than a mental illusion built by a killer unable to let go of the past.
Desperation bred suspicion, lies concealed crimes, and the abyss in the human heart was far darker than the fog over an isolated island.
At last, the long-held regret over the cellar sealed shut twenty years ago was resolved. All the illusions came crashing down, and those trapped in the darkness were finally set free.
