During the Guangxu period of the late Qing Dynasty, the Ministry of Revenue minted 10 "Kuping seven coins and two cents double dragons playing with pearls silver coins", with a map of the "Beiyang Navy Military Pay Treasure" hidden on the back. Each silver coin corresponds to the key coordinates of a treasure. After the silver coins were lost among the people, they were called the "Ten Treasures of Guangxu". The holders died one after another, and it was said to be a "blood curse" among the people. This serial murder case revolves around the fight for the "Ten Treasures of Guangxu" and cracking the treasure code. The murderer used the "blood curse" as a guise to imitate the death of silver coin holders in history.
