Kei Xun's words still lingered in his mind.
He listened to her attentively, aware that extracting this kind of information from the System would cost him dearly. Though her words reached his ears, his mind was still wrapping around what she said, still struggling to fully process what she revealed.
But he knew that the bottom line was, he needed to get used to using the Invincible Apparition.
It was unclear when he could absorb the Invincible Apparition for good, but he had to be ready.
And allowing the Invincible Apparition to take control is the way to do that.
Being in the backseat while the Invincible Apparition controls his body is a scary sensation.
Rex didn't like it as it reminded him of when he went berserk.
Fortunately, he's in the Spirit Realm, where there are few to no people whom he cared dearly for here.
Nobody to hurt.
Rex closed his eyes and steadied his breath.
"Sigh… Here goes nothing. Go on, I'll trust you. Take control and find Kaelthar."
