Chapter 507: Spectator 'Qin Yun'

Kuishi, who was flying over rapidly, saw this scene from afar. Her heart could not help but jolt. Frost Shark had only exchanged a few blows with Yang Song before he lost his life. He had died too quickly, so quickly that he didn't even last a few seconds.

"He burned his Essence Soul?" Kuishi was alarmed when she saw Yang Song's terrifying aura. "He has really gone mad. He doesn't even care about his cultivation anymore."

Qin Yun, who was originally tasked with restraining the eighteen fiendish servants, sighed as well. "So the ultimate move up Brother Yang's sleeve was to burn his Essence Soul."

The souls of ordinary mortals were very important.

As for Skyimmortal Essence Souls, they were even more important. They were practically vital to their very being!
