Chapter 979: Mysterious Realm

*Rumble... Rumble...*

As time passed, the rumbling in the sky became louder, and the lightning that continued to strike there also became more intense, as if the heavens were venting their anger, especially since they had repeatedly failed to kill Ling Yun. This time, they also didn't have the chance to do so, especially since he was only trying to break through one minor stage.

*Zap... Zap...*

A huge white lightning dragon swooped down towards Ling Yun and struck his body, but his expression remained unchanged, as it simply tickled him; his lightning soul and core immediately absorbed it.

*Rumble... Rumble...*

Ling Xi, who was looking up at the sky with a mocking smile, suddenly raised her eyebrows, but Zhou Yu immediately told her. "I asked our old friend to come here, especially since his private realm is not far from this realm, and he can help Ling Yun increase his soul power."
