Rex recoiled backward when crushing her heart didn't kill her.
Her astral voice spooked him.
Forged through countless battles to the death, Rex immediately summoned all three of his Soul Artifacts and activated all of their Spirit Genesis. A golden disk manifested and got in between them. Hard gold exoskeleton draped across his body like a second armor. And then he used the Inevitable Death to grasp Morgana's brain.
In addition, the Law of Inevitability, Misdirection, and Foresight was also activated.
The Law of Inevitability made sure that any attacks that she threw at him would miss. His second Law, the Law of Misdirection, made sure that any energy she used would fail to gather. And lastly, the Law of Foresight made sure he could see any possible attacks she could launch.
Nothing would surprise him.
Rex placed as much distance between them to get away.
He trusted the System enough to consider this a massive threat.
