Dark Qi

Furthermore, Shen Fei could clearly feel that the violent energy was continuously being transmitted into the demonic beast's body, causing the dark Qi within it to grow more intense.

Shen Fei's eyes seemed to tremble. It should not come as a surprise that this demonic beast had some extraordinary secrets. Otherwise, it would not have been able to transform the dark Qi in its body into such a violent one.

At the thought of this, Shen Fei immediately sent out his own Qi.

"Roar..."

In the next moment, a series of miserable screams echoed throughout the cave. This was the sound of the dark Qi being attracted to something.

All of a sudden, a rumbling sound came from the depths of the cave, and the entire mountain peak seemed to quake. Immediately afterwards, Shen Fei saw the demonic beast's figure.
