Boom!
With Dou Li's roar unleashed, Guo Chen's face immediately changed.
Clearly, he knew exactly what the "Moon Howling Sky Wave" that Dou Li employed was capable of.
The kind of... consequence it would bring!
In fact,
As Dou Li's words fell, the invisible sound waves also burst forth violently from Dou Li's mouth.
The sound waves, intangible yet more substantial than solidity, carried a terror of might as well as a terror of killing aura and intent.
A roar shook the great hall violently as if it was about to completely collapse.
And the weaker ones bled from their seven orifices, convulsed on the ground, and just like that, died on the spot.
The sound waves were invisible, silent even.
But they were more terrifying than any sound.
Silence defeats noise!
This was the "Moon Howling Sky Wave".
The signature Martial Art of the Moon Howling Heavenly Sect.
Ranked as Mid-grade Earth Martial Art, the difficulty of practice was extraordinarily high.
