My Disciple Plays It Too Safe

Abandoned as a child, she was taken in by an immortal envoy and taught the ways of cultivation. Her master realized she is a prodigy who has already reached the highest realm, but to keep her from getting proud, he lied and said she was just a hopeless dud. Finally with nothing left to teach, he tells her she has made no progress and sends her down the mountain to find her family. Down the mountain, she meets someone being hunted and saves him!
