Tips:

The lst floor of Qin-Shi Tomb is called Audience Chamber. "The audience chamber boasts the largest area in the Qin-Shi Tomb. The general view from the entrance of the Tomb alone shows the sheer massiveness of the chamber."
The mobs' level ranged from 81 to 85. Be careful about those mobs with curse skill. There's only one unique spawn in this area, the Tomb General Hyun. And please notice that the quest monster wanted by the Merchant Guild also spawn in this area.
