However, while she was occupying my body, I could go to her and control her actions! Moreover, the spiritual energy in my own world and the magic power in the witch's world are the same energy! Although this witch doesn't seem to be very strong, the knowledge here is quite valuable, but... After I returned to my original world, why was I treated like a genius for no reason? What did the witch do? … "Huh? You ask me, the great Witch of Origin, to eliminate slimes and goblins for the villagers..." In another world, the silver-haired witch looked at the list of requests and laughed.
