Fang Du grew up in an ancient environment. Although he lacked ancient techniques, his spiritual perception surpassed that of the outside monks. Even when holding his breath, he could detect the slightest differences in the spiritual environment.
If Zhang Er's body hadn't been a White Fox, it wouldn't have resembled a monk's spirit so much. I'm afraid Fang Du would have detected it the moment I entered Yong'an!
What else could make one feel oppressed at the peak of Foundation Establishment, at a stage where the spirit is lethargic, other than the realm of Jiedan?
No wonder Ye Fengsheng was so confident earlier! No wonder he could navigate Yong'an with such ease! It turns out he had a monk working for him within the Qidan territory! With someone to fight for him, no wonder he could act so recklessly!
"I know what you're thinking," he said.
