As Xuandu let out that bold, resounding howl that echoed through the Three Realms, the deathly silent Hunyuan Tribulation Cloud above the Nine Heavens seemed like an ancient ferocious beast that had been thoroughly enraged, instantly going berserk!
Boom-crack—!
A thick Chaos Divine Thunder, powerful enough to pierce through the Great Thousand World, tore through the pitch-black clouds.

Hum!
A colossal black-and-white Taiji Diagram, nearly covering half the East Sea, suddenly surged into the sky
