The Imperial Jade Seal, coveted by emperors throughout history since the end of the Qin dynasty, turns out to be a forgery carefully made by Qin Shi Huang himself. The real seal has lain hidden beneath Dongting Lake for two thousand years, sealing the lingering soul of an ancient evil and concealing a secret capable of overturning the very legitimacy of imperial rule.

Hunted by a crime lord who rules the black market, he uncovers the blood-soaked destiny guarded for generations by the shamans of Chu: the fate of the land has never been defined by a single seal.
