The Dragon Vein of Cangshan

A bronze coffin unearthed beneath the Qinling Mountains reveals a secret buried for a thousand years. Shen Ling, a retired soldier and heir to a line of tomb raiders, is forced back into the trade after finding half of a dragon-patterned jade pendant left behind by his uncle before he disappeared. He turns to his childhood friend Jiang Kui, who made his fortune dealing in grave goods at Babaoshan, and meets Gu Qingyan, an archaeologist willing to do anything to find her father.

More terrifying still, someone began digging through the door twenty years ago.
