FamishedGod
Honestly, it doesn't sound bad to give his body to his children. Not like he will have any anytime soon due to the real world being in such a situation. On the other hand, are you sure you want to add so much development to an illusion that will turn out to be fake? That Ruo and that Fei will be gone when it's over. It's basically the same thing that ruined Eternal Family due to developing chars and erasing them after. I, for one, can't really feel excited or enjoyment from his inner illusion, knowing he will wake up and lose whatever happened there.
