Natasha looked at the young man crouching in front of her with a puzzled expression and hesitated for a moment before saying, "You... could you be an Alchemist?"
Angel raised his eyes to glance at Natasha, nodding his head, "Sort of."
In fact, Natasha had not paid attention to the outside world for a long time, and given the recent changes at the Black Castle, even though Angel did not conceal his face, she did not recognize him.
Natasha did not resist having her mechanical body repaired by Angel because she knew that even if she could return, it would probably take a long time to wait for repairs. It was possible that she would need a complete overhaul, which would take even longer. Now that someone was able to repair her, even if it was just to restore her mobility, that was enough for her.
Although Natasha was actually somewhat doubtful of Angel's Alchemy skills, she felt reassured since he was associated with Illusion Demon; thus, she thought he could not be too shabby.
