"Not good! I'm too weak, this lightning can't hurt him at all!"
Yunxiao put away the hammer, then summoned the dynasty Bell and cast several incantation seals into it, producing a distant and clear sound as he tried his best to resist the sound wave attack.
"Pfft!"
The four-star Martial Emperor couldn't hold on any longer. He spat out a large mouthful of blood, and his eyes began to lose their light gradually. His eyes were filled with ruthlessness, and the aura on his body began to become strange.
"What's going on?" The five-star Martial Emperor was shocked. He noticed that the four-star Martial Emperor was looking at the two of them with a strange expression. He seemed to be unaffected by the sound wave as he walked toward the two of them.
The four-star Martial Emperor suddenly brandished his halberd and slashed it at Yunxiao!
Yunxiao's face turned cold as the hammer appeared in his hand and he suddenly struck the dynasty Bell, sending out a wave of lightning!
