Ouyang was actually quite familiar with this kind of breathing.
Every time he heard it, he seemed to make his entrance as some great villain bent on destroying the world!

Whether he was facing that eye of the Heavenly Dao in the Tang State's Mortal World or the Demon Ancestor in the Demon Ancestor's Mortal World.
As agents of their Mortal Worlds, they could forcibly mobilize all the power within them.
When they mobilized the power of an entire Mortal World, it naturally stirred a resonance throughout Heaven and Earth.

Even a Great Cultivator would seem insignificant and powerless before an entire Mortal World.
That was power enough to destroy a whole realm of Heaven and Earth.
Each Mortal World was a complete realm of Heaven and Earth, and naturally carried the might to destroy one.
If he had not been able to fight, he probably would not have been standing here in one piece!
And that was only a Mortal World, not the entirety of Heaven and Earth!
The Heaven and Earth Breathing of just one Mortal World was enough to destroy a realm of Heaven and Earth.
But this was the Cultivation World, and the breathing that had just sounded in his ears belonged to the entirety of Heaven and Earth!

At most, they could stir a resonance
