"I see." Zhan Sheng nodded. "And what about the technique for getting into the Devil's realm?" 

"I've heard it's called the Yin Yang Devouring Spiral. The technique utilizes opposing forces and energy to create a spiraling vortex which involves tapping into the darkest depths of one's chi, allowing the user to temporarily cross over into the devil's realm."

Zhan Sheng's thoughts go back to the conversation he had with his father right before he married Lei Bo regarding the devil's realm. Five devils ruled the realm.
