Because right now, nobody from Old Master Xiao's side dares to make a move, all because of the critical figure that is Situ Xin. From this incident with the Xiao Family and Xiao Yanlei, everyone has become aware of Situ Xin's capability. They are frightened that if they take any action and manage to release Xiao Yanlei from the Disciplinary Committee, it would anger Situ Xin, who might then turn his spearhead towards them.
