The quest is given by Ma Feibai, a guard captain standing at the western entrance of the City of Chang'an. He will tell you of the Great Emperor's clay soldies, who have become alive and are now about to overrun the city. You are sent to the Mausoleum to look for the source of this chaos. Reward: 2 Attribute Points (from the Spirit of the Great Emperor), 30000 Experience, random Amulet (both from Ma Feibai).
