He let her go and she dropped to the ground but she didn't drop in one piece. He had formed a blade construct on his other hand using light and fire. The red glass object looked fragile but it is very sharp. He was able to cut off one of her arms in a smooth and swift motion.
She didn't see it coming at all. It was swift and unexpected. She felt relief that she didn't know she was experiencing before the pain hit her. The contrast in emotions outlined that she had felt relief that she wouldn't die more than she thought she would. It also made her rein in the reflex to scream in pain.
Instead, she stood back up and picked up her bleeding arm from the ground.
"Thank you for your consideration, exalted demigod. I made a mistake and you corrected me. I am happy to say that the lesson has been learned."
She had to appreciate him. The way he cut her arm off is a warning and a message that he could have killed her earlier without her being able to struggle.
