He assembles a team—Fatty and Qin Miao, a master of Miao poison arts—and sets out for four perilous ancient tombs in the snow mountains, desert, deep sea, and forest. Along the way, they overcome deadly traps, battle guardian beasts, and match wits with the ambitious Black Feather Pavilion. After surviving countless brushes with death, they uncover a thousand-year-old secret: the Sui Marquis Pearl is actually the key to the First Emperor's true tomb. Drawn into a feud between factions of a secret-keeping family, they finally face the ultimate trial of the imperial mausoleum and protect the legendary treasure of the pre-Qin era.
