Honestly, that Zhao Yue is really stupid. It's one thing for her to abdicate her position as disciple, but why go out of her way to antagonize her old master? Deliberately setting him up to be killed, what's the point? If he's killed by outsiders, that'll mean his treasures go to them. She'll get nothing in the end. Isn't it much easier to just lay low and wait the 5 or so years it would take for him to die of old age instead?
