Chapter 778: Return

"Boom!" The explosion shook the entire Snow White Mountain. Not only it created a huge shock wave to the surrounding, but the thunderous sound also reverberated in everyone's ears.

*Rumble Rumble!*

The thunderous sound seemed to be followed by a rumbling sound, which obviously didn't come from that Thunder God Cannon. The elders immediately realized what just happened and looked at the mountain, watching how the snow that covered their mighty mountain suddenly fell down, causing an avalanche.

"!!!"

When the smoke disappeared, the sect master and the two elders were in shock. That attack just now was a few times stronger than their most powerful attacks. If that attack hit them, it would probably have heavily injured them.
