Killing Jeremy was a feat that was not difficult for Corey to achieve in the slightest despite the fact that Jeremy was still in the shell world and he was outside of it.
Corey had used the skill, Toxic Familiar, to implant two poisonous insects inside Jeremy's heart and head.
He had done this from the moment Jeremy told him about his unique ability, he had placed the poisonous insects in Jeremy's body when he touched him back then.
Although it was quite unfortunate he had to kill Jeremy, but to save his sister?
He would become the incarnation if that was what it took to save her.
As for what Jeremy's reaction would be if he eventually found out that he was the one that killed him?
He didn't care.
If he became angry with him, then so be it. He would deal with it in the future.
Meanwhile, what was currently going through Corey's mind was what his next set of actions should be.
Before killing Jeremy, he had a brief plan in his head.
