Ye Qifeng casually brushed a hand over the Purple Jade Crystal Ring.
He took out the green and white jade bottles he had asked Yue Guan for, then wrapped them in Spiritual Power.
He then formed a hand seal.
As the Yin-Yang Mark on his brow flickered, Ye Qifeng's spiritual body carried the two jade bottles into Yin-Yang Space.
Ye Qifeng sat cross-legged in the middle of the Yin-Yang Taiji, suspending the two jade bottles in the air.
With a movement of Spiritual Power, he flicked open the stopper of the green jade bottle and drew out the Jade Phosphorous Serpent Poison stored inside.
The Jade Phosphorous Serpent Poison was a viscous liquid that gave off a faint green glow.
It looked both disgusting and terrifying.
The green jade bottle Yue Guan used to hold the Jade Phosphorous Serpent Poison was clearly no ordinary item. It could isolate Soul Power and slow its dissipation.
At that moment, Ye Qifeng's thoughts stirred, and he began operating the Yin-Yang Heavenly Technique.
Borrowing the power of Yin-Yang Space, he used the Yin-Yang Analysis skill on the Jade Phosphorous Serpent Poison, beginning to analyze its essence, patterns, and laws.

The Jade Phosphorous Serpent Poison was essentially still Soul Power, except it contained a trace of poison-attribute law.
By the understanding of higher worlds, the essence of Soul Power was actually the primordial energy of heaven and earth.
The manifestation of this trace of poison-attribute law
