Xia Qing was just a stubborn scion who had never seen the real world.
When he saw the photos of the scene provided by Yu Li, he immediately threw up, then confessed, "I just wanted them to destroy the Feng Shui Array at Yang Yu's house, I didn't order them to kill anyone..."
After hearing Xia Qing's confession, Yu Li immediately took out the list of casualties from the scene and matched them, finding two people were missing.
One Big Iron Hammer, one Daoist Xuanxu.
However, Yu Li wasn't very interested in these two because, so far, they hadn't done anything wrong, and it was possible that they had just left when the situation went south.
One a worldly ruffian, the other a worldly swindler, she wasn't going to waste effort to look for them.
Xia Qing confessed everything, including how Xia Shangbin had found those people, clearly and in detail. Yu Li was certain he wasn't hiding anything, so she threw him into the cell.
As for the sentence, that was a matter for the court.
