As soon as Xue Mie's voice fell, a dark sword light suddenly appeared, and a terrifying sword intent raged in the black fog.
Xue Mie and the other battle monarchs' pupils contracted. Their spiritual energy surged as they dodged or blocked the attacks. However, the remaining three battle kings were not so lucky.
The power of the sword light was far beyond their imagination. In the black fog, their perception ability was greatly reduced. They had only just sensed that something was wrong when their bodies were slashed by the sword light. The next moment, their consciousness dissipated.
The remaining six battle-emperors looked at the dead battle-king, and their pupils shrank. They immediately huddled together. The battle-armored battle-monarch roared in anger, and gray light surged around his body, forming a huge defensive light shield that surrounded them.
The other battle-monarchs also started to channel their spiritual energy and looked around vigilantly.
