The sudden receding tide and the silence made Shen Yanxiao have an ominous premonition.
All of a sudden, an ear-piercing sound echoed in Shen Yanxiao's mind. That sound did not enter from her ears, but directly pierced through her nerves and went straight to her brain!
Her entire mind was in pain from that voice.
Yang Xi, Vermilion Bird and the others also revealed expressions of pain.
"It's the merfolk's soundwave." Xiu's voice echoed in Shen Yanxiao's soul, and his slightly cold voice instantly covered the soundwave in her mind.
"Sound waves?" Shen Yanxiao breathed heavily as the pain faded.
"One of the few offensive skills merfolks possess. This kind of soundwave cannot be detected by ears and it will directly attack your brain." The moment Xiu's voice sounded in Shen Yanxiao's mind, her body was immediately covered by a faint light. That light spread from Shen Yanxiao's body to the trembling sky dragon and covered Yang Xi and the rest.
