Chapter 665: [Unlocked: *Essence*]

Nux's eyes then fell on the last thing he had received after the System was updated,

[Unlocked: *Essence*]

Nux tapped on this message and soon, a Black colored book appeared in his hand.

"A book?"

A frown appeared on Nux's face.

"What is this, another Spell?"

Amaya questioned.

"It's a reward for becoming an Emperor Stage Cultivator."

"A Reward? It is not an ability this time?" Amaya frowned.

"I was thinking about the same thing." Nux nodded.

Usually, Nux gets an ability as a reward whenever he levels up, these abilities always prove to be incredibly useful, therefore, Nux and his wives were looking forward to the new ability he would unlock, but this time…

The System seemed to have different intentions…

"What is it exactly?" Amaya questioned, asking about the description of what this book was.

Nux nodded at her and then, he glanced at the book, this was how normally the information of the System Spells, or Skills appears in front of him.
