The roar that pierced through metal and cracked stone was vast and mighty, materializing in the underground space.
It was a sound wave that was visible to the naked eye. It surged up from the ground and spread in all directions, sweeping to every corner of the underground space.
Everywhere it passed, the air clearly poured to the sides, revealing a large expanse of empty space.
It swept all the way to the dome, to the four walls, to one's heart and soul!
This terrifying beast roar actually had mental destructive power.
Su Jingxing didn't know about the others but he felt a sharp pain in his brain. Even though it quickly disappeared under the buffer of his powerful soul power, this sound wave attack still made his heart palpitate.
He looked at Bu Qing, Gu Zhanlin, Fan Qi, Lu Wuchang, and the others and realized that they were indeed pale-faced and sweating.
