Back to the Peak.

"Let's see."

Ozul muttered as he released Ball of Purity out of his body in the gaseous form.

Irvin and Haley were both creeped out of the black gas exuding out of Ozul's body. They were sure that it was not a Mage's Spell since Ozul didn't even blink all this while.

Everyone was aware of casting the Spells without chanting, but even that required a Mage's complete focus on the Mana to guide it as such.

Moreover, the old couple felt no Mana fluctuations at all! Though they had lost their cultivation, they still retained their senses.

Sensing the fluctuations of Mana wasn't any difficulty for them. However, no matter how Irvin thought, he still did not back away. He felt that even if Ozul wanted to harm them, he wouldn't be able to do anything.

Though Ozul could sense most of the things, he did not have a particular skill for this. That's why he wasn't even able to detect if they had any Core at all.
