When she reappeared, I found that she was at the edge of the arena.
Usually when a person disappeared like this, they would appear right in front of the one that they were facing.
However, Bi Xue did the exact opposite of this by going to the completely opposite side of this arena.
After she landed, she immediately raised her hand and there was magic energy that gathered around her.
I immediately understood why she did this.
There were different balls of energy that formed around her while at the same time, there was a barrier that appeared around her. She clearly wasn't someone that fought in close combat, she was clearly someone that fought with ranged attacks.
So what she was doing was creating a stable stronghold that she could attack from.
