Jiang Wanyin and Aloy
Jiang Cheng had been so focused on the current close battle, so it took him a few extra moments to realize someone had sat down near him. He recognized her from the fight and thought that she had done very well. He wasn't familiar with her fighting style, but it had been interesting to watch.
He was about to talk to her when he saw her touch the side of her head and then focus on a point in front of her. He watched her for a few moments and realized that she looked to be reading something. He saw that expression on many scholars when they were studying.
However, there was nothing in front of her that he could see.
