After almost four hours of training, Arad didn't get to fight anything, not even once. The only fighting that happened was Diana kicking his back whenever he made a mistake.
Each one of her kicks felt as heavy as getting hit with a hammer. Arad didn't even know why she was so violent. It took him a second to realize why she was acting like that. That was because he kept asking if he could fight the abominations.
She wanted him to understand that fighting the abominations is dangerous, and he was already considering that his back might break if he kept going for them.
By the end, Arad had learned many things, but he still needed to practice. It was quite tricky to avoid detection and even harder to track his targets and get close enough to eliminate them.
