Chapter 837: Spirit of Fighting Intent

Grooo!

The vast Nine Nether fighting spirit was raging like a storm, sweeping across the land. As the fighting spirit piled up, layer upon layer in the sky, it formed into huge waves behind Mu Chen.

While the fighting spirit was raging, everyone could feel a strange fluctuation emerging from it. The fluctuation was concealed, but it was undeniable. That slightest fluctuation could accelerate a person's heartbeat, bringing killing screams into their memories.

The eyes of the top powers narrowed and flickered. Finally, a few of the top powers, who had some understanding of the fighting spirit, recalled something that caused their expressions to harden with horror, as they looked at the Nine Nether fighting spirit wave with fear.

"This fluctuation... could it be?"

Lu Kui appeared pale, as he looked at the dark wave with incredulous eyes. Deep within that wave, the strange fluctuation caused his voice to crack.

"Spirit of Fighting Intent?"
