Zachary Ying is woefully unprepared when he discovers he was born to host the spirit of the First Emperor of China for a vital mission: sealing the leaking portal to the Chinese underworld before the upcoming Ghost Month blows it wide open. The mission takes a wrong turn when the First Emperor botches his attempt to possess Zack's body. Now, Zack must journey across China to heist magical artifacts and defeat figures from history and myth, all while learning to wield the emperor's incredible water dragon powers. And if Zack can't finish the mission in time, the spirits of the underworld will flood into the mortal realm.
