Cream-white flames filled one's eyes within this spacious hall. Many fire human figures stood straight-backed in this nearly ten-thousand-foot-large square hall. They did not emit any sounds, but an extremely terrifying aura saturated the hall. That aura merged together and transformed into a large fire dragon that lingered over the heads of these fire human figures. There was a killing intent surging from it.
Xiao Yan's group studied the formation in this hall from a corner. Xiao Yan's brows were involuntarily knit. This was not the first time he had seen such a situation. Ever since they had entered that large door, Xiao Yan's group had charged through three halls similar to this, but the further they progressed, the fire slaves they faced became stronger!
Based on the senses of Xiao Yan's group, every single one of these fire slaves in front of them possessed a Dou Zun strength.
