　　Rumble!

A huge sound rang out, sounds of enraged lightning instantly resounded between this heaven and earth. The roar made even the sky tremble in that instant.

Black thunderclouds were stacked in the sky as a colossal black lightning that looked like a black dragon was wiggling in the thunderclouds, emitting ripples of destruction.

Everyone was dumbfounded by the sudden scene. Even those as powerful as Wu Ling, Xue Tianhe, and Liu Qingxun were shocked since they did not sense any peculiar fluctuations earlier.

"What a sly method."

Liu Qingyun spoke with a heavy voice. At this instant, he finally understood what was going on. The divine wheel that Mu Chen had used wasn't his final move. The true ultimate technique was the lightning that was hidden behind the divine wheel.

Mu Chen used the divine wheel to cover it up. When he was drawing in the boiling Spiritual Energy between this heaven and earth, he secretly covered up this ultimate technique of his.
