After her master died, Wan Zhiyao stepped up to raise the six children adopted by the Guiyi Sect, only for those brats to cruelly kill her.
There was only one reason: her existence was blocking their path.
As she lay dying, Wan Zhiyao glimpsed the secrets of fate and learned that the youngest of the six children was the heroine, while the oldest was the male lead.
She was a cannon-fodder supporting character, a stepping stone for the protagonists.
Fortunately, she didn't die. A little mouse saved her instead.
