The Great Void King, although fast-fleeing, was still swept away by the sound waves. Eight Heavenly Dragons intertwined, forming a golden hammer hundreds of feet long, crashing down from the sky!
Boom!
The invisible sound waves fiercely descended! Besides the Blood Heavenly Dog, even a fish in the river drifted as if unwounded because only demon ghosts could sense these sound waves, neither ordinary people nor Martial Artists could hear them.
If the Sound Wave Kill couldn't be heard, naturally, it inflicted no damage.
"Damn it!"
After the hammer strike, the Blood Heavenly Dog was covered with cracks, and its evil energy dispersed.
The Cold Mountain Elder said emotionlessly:
"It's time to depart."
...
Time passed.
Unbeknownst to them, it was already early morning.
The 29th day of their trial.
In the Catastrophe Forbidden Zone, intense fluctuations were intermittently transmitted.
Faintly, the entire base trembled.
The might of the Heavenly King was terrifying indeed!
