"Absence of magic power in this world?" Nightingale had her doubts. "Will the world still be the same as it is? Why do I feel that the two of you are overthinking it?"
"… Indeed." Anna recovered from her daze. "The effect of a force is easily felt, where the simple addition of an unremarkable component force into a balanced system will definitely induce change to the system, let alone magic power that exists everywhere. If magic power truly appeared out of nowhere, then the world before its existence ought to be completely different. But from your description, our world here sounds really similar to that world, where water flows, snow melts, the sun provides warmth and where mother earth provides life. Aside from magic power, it sounds exactly the same."
