I don't know, can Shan Rou be killed that easily? She attempted to kill Zhao Mu several times and although did not succeed w/o XSL's help, she still managed to escape with her life. I have a feeling Zhao Ya will kick the bucket soon.
Darn, option A has no support . Btw, is Tian Dan the guy that masterminded the famous attempt to assassinate Qin Shi Huang by hiding a dagger within a rolled up map?
