Xu Hao listened to the girl's story with a smile and said, "Dirty stuff and the like are just used to scare people, but since he was injured by the vibration, it means he isn't a fraudster and must have some real skills, just not fully mastered."
"Nevertheless, his willingness to help, taking only the money for traveling expenses, shows that his intentions are good at heart, just lacking in power. It's possible that his senior fellow apprentice could really break the Formation here."
Xu Hao understood why the Taoist didn't mention the Formation but talked about dirty things instead. Compared to the tales of dirty things, concepts like the Formation were too mystical for many people to understand, and it was simpler to fob people off with tales of dirty things.
There are many folk legends about dirty things, but stories about Formations are far fewer. Perhaps the storytellers do this on purpose, not wanting ordinary people to get involved with the ways of Formations.
