Comments of chapter undefined of Force to protect the Male Lead [BL]

Wait wait wait. How did we go from demons to zombies? Also there's a real world, then the fake world which has a modern/old side? So the system can or can't go back to the real world since this one's fake? Was it just a trick? And only the old side has demons? Why would anyone stay on the old side if they knew about the modern side? (Aiden mentioned it before)There's so much going on 😖
