How did the legendary sword Jin Niang die?

Jin Niang ate Shuming Dan and died. Jin Niang, also known as Su Jin, is very different from the game. She used to be the handmaid of Yutan. Later, because of the scale of Candle dragon, she learned divination, temporarily lived in a house full of flowers (not the owner of a house full of flowers), colluded with Lei Yan, and became a graceful figure, following Ouyang Shaogong, but was seen by Ouyang Shaogong. Finally, he ate Shumingdan (that is, Jiao Ming) and died.
