Wu Feng stretched out his hand and said: "Junior Brother, look, now the spiritual energy index at my eight positions ranges from 10 to 100."
"You can cast spells at will and pass through these eight positions of mine one by one."
Zhao Xing nodded, then a streak of thunder light appeared in his palm, the lightning resembling a wandering dragon, drilling into the area in front of Wu Feng.
The thunder light circled around Wu Feng then returned to Zhao Xing's hand.
"How is it?" Wu Feng asked.
"Spiritual energy index varies from high to low through the eight regions. The speed of the Thunder Skill slows down and its power weakens progressively," Zhao Xing summarized. "The Thunder Origin weakens due to insufficient spiritual energy index, causing my spell to deviate to varying degrees."
"Exactly, this is what we often call the Unstable Void." Wu Feng waved his hand, and the eight regions in front of him changed once again.
"That was an idealized Unstable Void."
"Now try again."
