Miracle
"What?!" Both Adam and Berger's eyes had widened in absolute shock.
Viktor continued, "Edward was born with a frail body. The slightest touch to his skin would cause him to cry out in pain. It was very difficult for him growing up as a child. We all thought he wouldn't live long, but as the years passed, his health continued to get better."
He paused for a brief moment, thinking of the right words to say. Then, he continued, "After his health had improved, we tested him for his talent in spellcasting, but we learned that he didn't have any."
"How is that possible?! Could the test you conducted be flawed?" Berger was stupefied. He knew for a fact that Edward had a B-grade talent. Moreover, talent was something that one was born with. There was no way one would suddenly develop talent in their later years.
