"Hehe... hehe!"
Gu Wantang suddenly laughed, her smile carrying an indescribable strangeness that sent chills crawling down one's spine.
The girl's originally rosy lips had turned scarlet. She slowly opened her eyes... madness gleamed in her gaze, making her as terrifying as a demoness born from hell.
Her aura was naturally peerless in its terror. Though she possessed only the cultivation of a first-life Great Emperor Realm, the pressure she exuded did not lose in the slightest to those Great Emperors who had lived a second life.
Her blood-red pupils were filled with madness. The woman lightly licked her red lips; the yin-yang power within her body had completely collapsed.
All the negative effects of the Lunar Immortal Physique had surfaced!

The total collapse of the yin-yang power within her allowed a supremely yin and evil malign entity to seize control of her body. This was not a heart demon possession in the sense of the Lunar Mystic Maiden—it had utterly twisted the primary personality, effectively wiping out Gu Wantang's original personality completely.
Yin Beast!
A problem many cultivators of the Nine Heavens faced when they possessed bodies of extreme yin or extreme yang.
For example, if a male cultivator with a Sacred Physique of extreme yang suffered a complete collapse of the extreme yang power within his body during tribulation, his mind would be warped by evil thoughts, turning him into a Yang Beast. He might be slain on the spot by other high-level cultivators, though such a possibility was exceedingly low.

But Gu Wantang's Lunar Immortal Physique was different—the number one supreme yin
