Yuan An begs Lan Zhi to give her three days to find the real culprit behind the courtesan’s death, and they join forces. While searching for leads, they come across a slave market and notice a wild man with the ability to communicate with horses. Seeing that he is treated brutally, Yuan An decides to buy him, but he runs off as soon as he is unchained. Later, the duo uncovers two shocking revelations: the courtesan died from hallucinations after inhaling opium, and the brothel where she worked is an opium trafficking hub. (Source: Viu)
