At the end of the Qing Dynasty and the beginning of the Republic of China, Chen Jiuchen, the successor of Beiping Mojin School Captain, was forced to return to the tomb robbing business in order to find his father who had been missing for ten years. After the northwest warlords exploded the Kunlun Dragon Skeleton Valley and unearthed the chain-wrapped dragon bones and white jade boxes, a strange sandstorm devoured the soldiers, and the undercurrent of the four major tomb-robbing sects surged. He formed an alliance with Sea Buckthorn, the last tomb guard girl in Shalu Village, and discovered that what was sealed in the jade box was the "Dragon Suppression Contract" established by King Zhou Mu and the Queen Mother of the West - which can awaken the dragon veins and destroy the Central Plains. The two went deep into the maze of sand seas and the black turtle burial pit, and uncovered the truth about the ancient transaction in the Mirror Ruins. A hard-core tomb robbing journey about blood, contracts and the balance between heaven and earth. It is thrilling at every step amid mysterious folk customs and historical suspense.
