Jason changed the word class to world. The sentence now read: "This woman is the best fighter of the world and easily wins against all the others."
With a bright flash reality changed again. Amanda stayed mostly unchanged. She was still a statuesque young woman in her early twenties. She spotted powerful muscles all over her frame and yet looked sexy as hell. The others had changed more drastically. All seemed to be stronger and fitter, all me men were really muscular now, far more muscular than Amanda. The instructor was on top of the ladder on the female site, just a bit behind Amanda. "Training with the best fighter in the world might also improve the others" he thought.
Instead of one after another, 5 to 10 people tried to attack her simultaneously, from all directions with full force. Even if most of the men were taller and stronger they did not stand a chance against her. Amanda easily dodged or blocked all the attempt and then countered their attacks sending one after another flying several feet away. Amanda looked a bit bored. It looked as if she was toying with them. Sometimes she just spun her head from left to right using her ponytail like a whip causing the attackers to go down just from the impact of her plait. They even tried to use some serious weapons like swords, knifes and bludgeons but she easily countered all of them with her bare hands.
Jason was not sure if she was bored or if she had fun. But he thought about giving her a real challenge.
With that, he selected Amanda and generated another sentence.
