I do love Ancient detective dramas but in this category The Sleuth of Ming Dynasty would be the gold standard for me. Not that the 2 dramas are completely similar as this is focused on solving super natural murder mysteries.

Positives:
Su Wu Ming -- Humorous with a slight sarcasm. By far the most interesting character.
Ghost mysteries -- Interesting decipher of fake ghosts murders with several different mysteries. Good pacing.
Political struggles between the Queen vs the Prince and some how the mysteries intertwined with them.
Decent fight scenes - Not amazing but entertaining.

Could've been better:
Character development -- practically none. I had to give the series a break when when it felt like nothing but solving mysteries. Bromance never really blossomed and Lu Ling Feng's temper remain the same.

Enjoyable watch overall
