"You dare kill my servant! Fine, very well!"
The Nine Netherworld Demon Monarch was clearly extremely agitated, yet upon witnessing this scene, he laughed instead of getting angry.
At that moment, the black aura around him gradually dissipated, revealing his unchanged appearance.
Even the right arm that Yang Yan had destroyed appeared once again!
"Are you really of the Demon Race?"
Yang Yan scrutinized the Nine Netherworld Demon Monarch from head to toe, asking with some curiosity.
This bizarre scene left Yang Yan somewhat astonished.
Such potent regenerative abilities, no wonder it evoked such a strong reaction from Sass.
"Now you know fear, but it's too late!"
The Nine Netherworld Demon Monarch stretched his right hand toward the direction of the creature's deceased body.
A black vortex began to form in the palm of his right hand.
As the creature's body came into contact with the black mist, it began to wither rapidly.
