To solve the mystery of the remains, Jinshi drags Maomao along on a journey to Binan-shu, the southern province ruled by the Bi clan. They arrive at a bustling city on the water. Maomao is excited to see herbs and medicines she has never seen before, but tensions are high in the area, as pirates are viciously trying to find the treasure their late leader hid away. “I hope nothing happens...” Jinshi’s premonition comes true.
