Cassian's challenge

Cassandra finished the last wave faster than even the first, dispatching all nine monsters—including the massive one—within seconds of the fight beginning. Both Cassian and the Guardian were left speechless, watching the aftermath as the defeated monsters struggled to move before going completely still. Breaking the silence, Cassian cheered loudly, "Detective!" 

The Guardian, still frozen in shock, showed no sign of anger. Instead, a wide grin spread across his face as he muttered, almost to himself, "Amazing... amazing. These people are going to make me perfect my challenges."

Turning his gaze to Cassian, the Guardian's smile deepened. "Your turn now, boy. Let's see if you can surprise me as much as she did. And don't forget our bet," he said with a knowing glint in his eye.

Meanwhile, Cassandra leaped out of the arena, bloodied but wearing a triumphant smile, her exhaustion overshadowed by her sense of accomplishment.
