Chapter 290_2

"The sonic waves have grown stronger again, such intensity, without reaching Nirvana, Liè Yàn should be almost at its limit."

"The sonic waves are still intensifying..."

"This place... Huh? Have we reached the end? However, with sonic waves of this level, I wonder if Ling Xi and Yan Yourong and the others can break through."

Cao Zhen quickly reached the top of the tower.

At the top of the tower was its spire, not very large in area, where three objects were placed, one of which was a large drum.

The earlier sounds had emanated from this drum.

The drum was entirely black, and its surface was painted with patterns of ferocious beasts.
