Genre: Mystery

A concubine passes away, and a woman goes missing. Jinshi sends Maomao to investigate – not these incidents, but mushrooms growing in the rear palace.

The caravan stirs up excitement in the inner palace. The merchants bring all kinds of goods. However, something gives Maomao a bad feeling.

Lakan must now choose a courtesan to buy out. As a high-ranking military official, he can afford to freely choose, even from one of the Three Princesses. Who will he choose? Who does Maomao really want him to choose?

No longer willing to keep running away from Lakan, Maomao decides to face off against him. She challenges him on his own turf, in a chess match.
