Chapter 664: Unparalleled Power, Powerful Secret Manual

Ye Feng grinned. At this moment, his aura was surging, and waves of bloodline power were surging in his body. Every single move of his was filled with an unparalleled power!

"So this is the third level of the [Dragon Vein Technique[!" Ye Feng mumbled to himself. That move just now was the ultimate meaning of Slime!

With Ye Feng's current cultivation, the [Slime Power] had reached a terrifying level!

He raised his palm, and the skin on his arm became dark and rough. The veins on his arm were bulging like tree branches, making him look extremely ferocious!

At this moment, Ye Feng's body was tall and filled with strength, and his eyes were red like flames as he stared at the rock ball in front of him!

"How could this be?"

The rock ball was extremely shocked, looking into Ye Feng's eyes. It felt as if a desolate beast aura was spreading!

"Who are you?" the stone ball asked in fear!
