Treacherous Cases in Shendu

Li Ya'er stood in for the father and went to receive a bride. That same night the bride set fire to herself and died, and no explanation was found. Hired killers then attacked Li Ya'er, who lost all memory and was kept as a slave. A love formed between the slave and the slave's master, one their positions forbade. A conspiracy that had already cost lives came into contact with the secret of who Li Ya'er really was, and the master and the slave were put on opposite sides with a blade between them. A princess who kept two faces and a killer with a cold stare worked together against the conspiracy, with the Tang Dynasty at stake, and they worked in the dark.
