Me and My Magician Sister

Correct, can it really only be judged by the results? If the result is optimal, is it really correct? … "The most powerful magician of the past era" This title belongs to my father. Due to his experiment on "conceptual magic", my father's magic power leaked and he became a sinner in the world. He disappeared in 1999, leaving behind my sister and me. Ten years later, my sister and I both became third-rate magicians in the magic school and lived an ordinary life. All that our father left us was what others said about us: "children of sinners."
