Chương 442: Immortal Dawn Sword Mark Left on the Beast Skin

In the Grotto-Heaven Dao Palace.

Cui Heng stared at the pitch-black smoke surging in his palm and frowned.

He realized that he was actually unable to see through the essence of this energy. He could only feel chaos, mania, and a few pure violent auras from it.

This aura was like the darkest and dirtiest power in the universe, symbolizing extreme negative emotions. Even a Soul Formation cultivator's divine sense could not see through it.

"If I'm not wrong, this should be the remnant aura of a ferocious beast." Cui Heng thought to himself, "With my current cultivation realm, I can't even see through its appearance. This is at least equivalent to the Peak Soul Formation realm or even the Return to Void realm."

Although there was an extremely huge difference between every small realm of the Soul Formation realm, they were still in the same major realm after all. There were always some characteristics that were interconnected.
