As soon as the two boys wake up, they find the treasure map of the Kuangli department. The map shows the location of a mountain called Serpent Sea Mountain, which is believed to be the source of the amber spirit that enlivens jinglei city during the seasons. The tribe believes that the mountain is connected to the sea dragon, the god of the clan, and they have worshipped him for thousands of years. However, in the last hundred years, the tribe has done many wrongs, and the word "department" has been replaced with "clun," the name of a clan. The two boys leave a trail of clues on the mountain, and everyone is instructed to wear masks to protect themselves from the serpent's qi.
