"Two children with Three Levels of Body Opening, what could be unusual about them?"
"They arrived last month, and seeing the Family Head's token, I let them stay in the courtyard. At first, I didn't think much of it, assuming they were just two kids with decent talents."
Hou Cun paused here, then continued, "But ten days ago, when the demons attacked the city, everywhere was struck except for our courtyard. Not a single mark of demon damage could be found. At first I was clueless, thinking we were just lucky, but later some brothers mentioned that they had seen a demon approach, only to strangely retreat at the courtyard's entrance. That's when I started to doubt those two."
Hou Yuxiao immediately grasped Hou Cun's implication and asked, "At that time, besides them, was there anyone else in the courtyard?"
