Boohoo—"
Suddenly, an extremely sharp and ear-piercing sound wave sounded in the void.
Circles of materialized black sound waves suddenly enveloped Chu Zhou.
At this moment, within a radius of a million kilometers, be it the living beings of the foreign universe or the native creatures of the Demon World, they were all overwhelmed by the demonic sound.
Countless living beings collapsed to the ground with a splitting headache.
On the battlefield, many creatures affected by the black sound waves were either severely injured or directly exploded.
Many mountains and forests on the ground were instantly reduced to dust.
On the battlefield, some living beings who were not affected by the aftershock of the demonic sound looked at a living being with a mouth like a loudspeaker and their expressions changed.
That terrifying demonic sound was emitted by this creature with a mouth that looked like a trumpet.
