[Ancient suspense + original reasoning + court intrigue + multiple reversals + brain-burning] In Chang'an City, three carvers died in a perfect secret room. Their death was like a ghost ball peeling off layers. At the core, there was a gold seal and an innocent soul who had been exterminated.
He was once the youngest minister of the Ministry of Punishment, but now he is a fugitive from the public eye. In order to clear his mentor's wrongdoing, he returned under a pseudonym, but got involved in a bigger chess game - the powerful eunuch, the sanctimonious prime minister, and the ghost worker lurking in the dark. Everyone wanted him to find out the "truth", and everyone wanted him to die.
Seven secret rooms, seven impossible crimes. The truth is like a magic ball, peeling off one layer and another. When he finally got to the core, he discovered that the person who wanted to cover up the truth the most was the person he trusted the most; and the real murderer was never in the secret room.
There is no blue sky above the court, only a deeper hell.
But he insisted on lighting a lamp in hell.
