God of Illusionary Needle

The story is about an old feud between two people - Liu Lang Yue and the feudal lord of the Yue clan. Apparently, horrible things were done to Lang Yue as a child, which left her horribly scarred, and now, she has to use a fake face. Since then, she has hidden 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 Lang Yue in the first place?
