Detective Dee Renjie: the Mystery of Heavenly Punishment

[Death in a secret room + prophecy written in blood + serial demands for life = Di Renjie encounters the most bizarre case in history! The Minister of Rites died tragically in the study room late at night. The doors and windows were locked, and there was a blood letter on the wall saying "Heavenly Punishment is Coming". The murder weapon disappeared out of thin air, leaving only pieces of broken porcelain. At the same time, three hundred miles away, the key witness in the imperial examination case died suddenly in prison, leaving the same bloody mark. Rumors spread, and the theory of divine punishment swept the government and the public. Di Renjie was ordered to do so at the critical moment, but found that all the clues pointed to a concealed imperial examination scandal twenty years ago. The real murderer is like a ghost, killing people invisible and always one step ahead of him. When the only survivor was also targeted, Di Renjie was shocked to realize that this was not only revenge, but also a sophisticated conspiracy against the entire order of the Tang Dynasty... And he may also be the next target on the "Heavenly Punishment" list.
