At the same time, I kept visiting the mirror world frequently, almost once per half an hour.
I didn't notice any change at all at the light intensity or something, didn't notice anything weird at all. It seemed like this clone just vanished in thin air, and wasn't here anymore.
I even grew suspicious at one point, checking with Lily on the current progress of the war. Things weren't that great at many fronts, but we were also winning at other places.
Not to mention when she withdrew our forces from the areas of Karoline, things started to heat up there. The enemies of other races focused on dealing with her as expected, throwing away tons of forces right now.
The enemy grew restless and a bit greedy about the continents Karoline controlled. Yet such greed was destined to backfire at the end. I knew Karoline was stronger than they took her for, and I even didn't see it surprising if she expanded her control over new continents.
