Comments of chapter undefined of Card Apprentice Daily Log

there seems to be a problem here, corey was supposedly only watching corey parks memory as a third party right? so I understand if it were to affect her as a whole but this should not affect her ability right? she couldnt have absorbed corey parks experience in skill by just watching right? and the inheritance did not mention including corey parks memory and experience in skills and only gave her assimilation to the demon core so what is this? care to explain?

Why do I feel like the main character is changing and I’m not liking it

Thanks for the chapter!
