Thinking of this, Ye Leng'an felt that she really suffered a huge loss this time. She didn't know whether she would still be paid for Zhongyu Yiran's treatment in the future. Now, she had to come all the way to the southern boundaries and use her spiritual energy. No matter what, she would be at a loss.
Above all, it was all her fault for being young and inexperienced back then. She found such a tough guardian for herself without investigating.
Huangfu Ruiling seemed to have sensed Ye Leng'an's low spirits. He gave her an odd look with a frown as if he was wondering why she suddenly became this.
Ye Leng'an shook her head and stopped thinking about it.
