"Burn! Everything!" Lu Sheng spread out his four arms, his body started to burn with purple black flame—this was the Yin Flame perfected to its limit.
The horrifying Yin Flame spread in all directions in the blink of an eye, igniting the blue sea of cloud.
"Boom!!!"
Purple light flashed, instantly igniting the sea of cloud. From the Secret Art Palace to the areas around it, everything was surrounded by a sea of purple flame.
The wildfire only circled around Song Zian, avoiding him, but still engulfed the black rock and the knife that was on top of it.
"Aghhhh!!" the voice inside the black rock screamed in agony. This Yin Flame could even damage Ancient Devils and Devil Masters like leopard-snake. It was definitely something a devil that wasn't even a lower tier Devil King in terms of power power couldn't bear.
The voice continued to screamed. The rock started to glow red, as if it was about to turn into lava.
