The story is about an old feud between two people - Liu Langyue and the feudal lord of the Yue clan.
Apparently horrible things were done to Langyue as a child which left her horribly scarred and now, she has to use a fake face.
Since then, she has hidden herself in a valley with two disciples, Jin Cheng and Jin Bao, and their buddies, a pack of wolves with Lassie-like tendencies.
As fate would have it, Lord Yue's eldest son decides to go hunting for wolves, and he ends up getting skewered with his own banner by Jin Cheng.
But Jin Cheng is also severely injured, having taken half-a-dozen arrows in the process.
Who else would save him but Tong Fu'er, daughter of the master physician Tong Yuan, the person who semi-healed Langyue in the first place?
She uses the poison from a bee to purge the venom of the arrowheads. This technique of using bee stings as acupuncture is called 'magical needle'.
He shows his gratitude by licking the girl's hand in front of her father, and they fall in love.
