Blind raised his head and smiled. "This brother, you said you found a sword trace on the wall of the Dao Sect that is different from the sword skills of the Dao Sect. Aren't you pointing it out for others? I don't know what you are investigating, but why would you tell others what you want to investigate like this? If Mu'er were truly the murderer, he would definitely change his sword skill."
Qu He's gaze fell on his body, and he said leisurely, "How do you know I'm not telling him on purpose?"
Blind was slightly stunned.
Qu He's hands were behind his back, and he said with a smile, "If he is related to this case, he will definitely hide his sword skill when executing it. I will know with a look if he's hiding his sword skill or not. Furthermore, even if he hides his sword skill, in the fine markings that construct the sword skill, on the fine runes formed by his vital qi, he will leave traces of it behind."
Qin Mu felt apprehensive.
